#Javaland 2017 wrap up

Yes – I did it again and attend Javaland conference in Phantasialand Brühl.

It was not easy this year to concentrate on the sessions because of the hottest march of the last 100 years. But the quality of the sessions beats the weather. Maybe again my invest in reading the abstracts and filter the sessions before the conference has payed off.

Day 1 Conference

Jens Schauderdocumentation & slides with AsciiDoc, Git, Gradle and Reveal.js

Jens shows in this early morning session how we can version and so diffing and merging our documentation and presentations via text based markup languages. Now I have to puzzle the pieces together for generating my future documents from code. One question remains – what if we have to share the work on the documentation work with non programmers?

Jean-Jacques van Oosten, Chief Digital Officer Rewe Group: The role of the CDO as Chief Product Owner

This presentation shows REWE as on the right way for digitalization. But somehow I did not get rid of the feeling, that this was more a recruiting campaign to get the right people for the job. Have to speak with some of my friends, which are working there in the field. Interesting is the goal to develop all IT itself and do not buy from competitors perhaps. This needs lot of money and resources.

Steffen SchluffSebastian Damm, OIO – Orientation in Objects GmbHMust Feature Branches and Continuous Integration contradict each other?

I know most of the facts already but here these was ordered and coherent derived from literature and practices. Conclusion – with the right tools you can live with the compromise.

Gorge Albrecht, Code Mentor: Readable tests with AssertJ

Unfortunately I come a little bit late, because there is not planned really a big break for lunch. It seems here I have missed the point before: I had hope that the test output is more readable for the tester, not for the programmer. The only disappointing session for me.

Sven Ruppert: Hacking with Mutation Testing

After I have heard Sven’s session for PIT framework last year on Javaland I found not the time till today to work with this. Unfortunately I bring my company laptop which does not allow to download files from maven over the VPN as the company man in the middle webwasher replaces the original certificates. Sven does his best to support me, but I could not solve this in this time. In the evening on my way to home a nameless attendee give me an hint to disable the ssl check in maven locally. So I could test Sven’s solution branch right before midnight successfully!

Carola Lilienthal, WPS – Workplace Solutions GmbH: From Pair Programming to Mob Architecting

A little bit late, I enter this fully packed room. This was announced before via “chili” in the conference planner, so no excuse for me. But as I could not make notes standing on the door in the last row, I think I have here to reread the presentation to give a concrete summary here.

Stefan Schlott, BeOne Stuttgart GmbH: Security in the development team

The presenter gives some hints for small development teams to make it fit for security. Unfortunately most of this are not happened in big companies too. Additional most developers are not interested in this too. In this session first I heard the term required Caretaker on this conference, which should repeated in several sessions.

Mario Mann, Novatec Consulting GmbH: Application Performance Management with Open-Source-Tooling

As session name promises: He show different tools for different purposes of APM including it’s own. Key message: No one tool for all purposes. Interesting some example test of the Javaland homepage.

Martin Thompson, Real Logic: Keynote: Listening to the Design Pressures

The second keynote starts with statement that “non functional requirements” should be changed to “quality attributes”. Further he states that in most cases all new hypes are covers of earlier research. So he recommend to first search for the original ideas. He mapped an example from 1983 and mapped several statements in the content to actual hypes. We have to bring back simplicity and other core techniques, as hardware will not grow anymore as in the past and will not solve our growing requirements. Doing it working and fast together in one step will give other design decisions as doing it separately.


While most other people try the rides of Phantasialand, I attend this format. Same motto as last year: show me your favorite opensource lib and I show your mine. Not all was interessant for me, but some of this I would never heard, when not here.

  • Lombok: Boilerplate generator, unfortunately not really usable in JDeveloper
  • SPI – Service Provider Interface: interesting, but see no use case at the moment
  • jQAssistant: QA for your code, very interesting open analysis tool, have to read the corresponding missed presentation
  • Form Checker: generic validation and creation of HTML forms for portals, no use case in our framework development
  • Future of Spring: concurrent JEE framework to ADF
  • Jax-RS Hypermedia: maybe later when REST required in our development

After dinner and some drinks I return to cologne.

Day 2 Conference

Elmar Juergens, TU München und CQSE GmbH: How sensible we use our quality analysis?

“From weighing alone the pig will not be fat”. Many analyse it’s code but do little against the results. He shows very entertaining the combination of research and practical steps to wake the interest to change the code. Again you need a Caretaker here. But remember “Management by numbers is not by professionals but by amateurs.

Rustam Mehmandarov, Computas AS: Field Notes of a Command Line Ninja

Lot’s of linux command line tricks, have to attach my notes to every bash call from now. Very entertaining.

Thorsten Maier, Orientation in Objects GmbH: Resilient Software Design Patterns

Good overview, key message: Use it only if you really need it, as it adds new layers to your software stack.

Falk Sippach, Orientation in Objects GmbH: Continous Architecture Documentation

This presentation was a good complement to Jens Schauder from Day 1. Falk shows the “documentation smells” as reasons to use here again markdown based documentation to generate to different target formats and audience. Additional he show some tips and tricks for the used tools.

Stephan Classen, Canoo Engineering AG: Robust, readable Web UI Tests with page object pattern, Geb and Spock

Good presenter, but I’m not really convinced from this wrapper tools (Selenium -> Geb -> Spock) in different technology stacks. Maybe sometime I will try it to be sure?

Frank Pientka, MATERNA GmbH Information & Communications: Load and Performance tests with ‎JMeter or Gatling

The speaker gives a very wide overview of both tools, I have definitely to reread this. Especial interesting is the feature of both tools (and the wrapper Taurus) to reuse selenium tests for load tests. Have to check this out!

Martin Reinhardt, Holisticon AG: Responsive Testing with the Galen Framework 

Presenter shows this interesting framework, but it same a little bit complicated to me. At the moment not usable for me, as it have no IDE Support for JDeveloper.

Thomas Darimont, eurodata AG

I had see some of this in last year “Meet the libs” format. As I had some plans for private application development, this seems the ultimately completest and free AIM solution for me. The speaker had deep understanding of the product and he packed this last presentation full with his knowledge. If you need somebody to set up your system, you should hire him!

Day 3 – Workshops

Gerd AschemannContinuous Delivery of Continuous Delivery

The trainer here has too a deep knowledge of the area and put all of this into this workshop.

We started with the creation of a VirtualBox via Vagrant. The we added script provisioner to install puppet into the box. With another script provisioner we start the installation and configuration of Jenkins via puppet scripts and modules. After that we installed Docker in the VirtualBox via another puppet script. On top of this we automatically create jenkins jobs to start a Docker container containing Maven and building there a simple Java Application. As last step we add an Nexus container to deploy the resulting artefacts.

The trainer provides us with some theory, but most time was practical work. Additional to the described steps we add some configurations for testing the created infrastructure and minimize the creation time of the infrastructure via caching.

The whole time we push our local git repositories to an central instance of the trainer where our environment are build (or not) via a central Jenkins instance.

The extensive workshop scenario, the different operating systems and bugs in the newest version of vagrant make it more difficult to reproduce all steps just in time. But we get all sources and slides to reproduce the scenario later at home.

Despite I have already started an similar scenario at home before, I get a lot of fresh input for my future work here. This workshop was every minute worth.


Same as last year: This was inspiring conference, which gives me a lot of fresh ideas and reminders for some spilled goals for my private and company projects. I think we’ll see us next year!

Improvements for next year

There are some for next year in Phantasialand:

  1. Please deliver stable and fast internet at least for the speakers and the workshops.
  2. Put the labs and commuity workshops out from the exhibition hall to filter the noise from soundchecks and nighthacking.
  3. If you see via the favorites of dukecon, that rooms are full, maybe you can change locations.
  4. For workshops provide big enough tables for comfortable working.

That’s it.

#DEVCAMP17 wrap up


Yesterday I attend the annual barcamp DEVCAMP of the DOAG development community. There are mostly developers with SQL, PL/SQL, Forms & Reports, ADF, JET background and some Java, Javascript and APEX developers too. And not to forget: 1 dba and some managers. Here are my summary.

I arrived on evening before just in time for the life cooking event and later at the bar to meet lot of the people I already know and some new too.

The morning begins with a short introduction to the format of a barcamp.

As warm up Jens Schauder starts with an talk about clean code. He begins to compare what the lack of hygiene for Middle Ages mean and the statement that we are in the IT Middle ages. In extreme cases not tested and not understandable software can kills people! So the task for every day is “write an test” and refactor the code to clean code.

Then the barcamp planning starts. In short time three slots are filled up and the really barcamp starts.


Influenced by the starting talk next there was a session related to clean code and how to implement the related processes. You should teach a little bit of the theory behind it. It is essential to decide all rules with the whole team and review the continuous use of it. If the rules are not followed, then first you should ask why this happens and listen for the reasons. Jens Schauder recommends here these books. Maybe you have to adjust the rules to convince all developers. But in extreme cases of deny any of the decided rules you should escalate and delegate this to the responsible manager.

Next session was about how to test heterogeneous applications, especially SQL, PL/SQL and Forms but others too. I mentioned here two possible strategies, which both has it’s tradeoffs:

I noticed here that testing is mainly seen as to check the contract between developer and customer, sometimes useful for regression test but seldom as required for changing or refactoring the code. The participants seems to be overwhelmed by the amount of tools and effort to do automatic testing. Yes – there is a lot to do in advance, which pays off later.

In the next break I get a shortcut for actual requirement for forms change to implement some kind of SSO without additional servers. I get some nice hints and have now to check, if one of this is successful. This are the advantages of networking here.

The we discussed about Alternatives to Oracle Reports. Seems that it depends on your requirements, which tool to choose. Please do an value analysis here. So if you need pixel exact layout or want not pay much money Oracle Business Intelligence Publisher will not your friend. If you search for an active community maybe you should not choose Eclipse BIRT or at least use the commercial version from Actuate. But both of these and Jasper Reports are used from present participants. Further alternatives seem to be SAP Chrystal Reports and Pentaho. And don’t forget to test exotic features like widows and orphans!

After a coffee break we discussed the future of Oracle ADF. The punchline here was: ADF is not dead, but JDeveloper is very buggy. None of the participants does really miss any bit feature, but most struggles with the IDE. It seems, that the problems are bigger, when you work on windows. Maybe some of the product managers should be forced to worked again with windows to see our problems. I have articulated there 2 problems with the ADF community. I we try to raise the acceptance we should not try to extend the focus of the activities to alternative technologies as MAF or JET. Second we should not self call ADF into question on every conference, we should leave this part to the fans of other technologies.

The last session again turns around automatic testing of PL/SQL, some repeating to the described session above.

In closing session most of the participants said, that they want to come back next year. Maybe it is better to put some fixed sessions or workshops, as this is easier to describe to the bosses as “I will go this event, but it is not clear, what will happens there.”


I have learned not so much new things this year, but I attend these time more the known to me technologies. But I get the confirmation, that most of the things we do or plan do to are on the right track.

Unfortunately I observed some people in the sessions, which comes only to search for finding confirmations to reject for itself, what at least the initiator of the topic want to do.

You find more informations in Twitter

That’s it!

#Javaland 2016 conference day 1

This year I have decided to give the Javaland conference a try. I’m not a java professional, but in the program was listed a lot of interesting testing presentations, so my company booked for me.

The location in Phantasierend Brühl near cologne was very fine. Unfortunately the conference rooms had not enough space this year so for some presentation you have to go to 2 rooms outside of the parc. Additionally it is not understandable, why there is not wlan for such a conference.

This was my first day:

Jeremias Rößler (ReTest): Behavioral Diff as new test paradigm

Why I don’t record a test with all information of my page objects, eliminate all variable parts until it is stable and reproducible and define this a my basic truth. If a code change break this test I check the problems, if these were expected or not. Good idea but – how many data created this and how long does it take to compare all this with previous successful run. I hope this new startup will give us effective tools for this paradigm.

Simon Maple (ZeroTurnaround): Is Your Profiler Speaking the Same Language as You?

When I can trust the Profiler, what are the basics of it and how can I ensure that the right data are available for it. Which traps exist, when instrumenting for tracing and logging. Nice insights, but I’m sure I have to reread the presentation to fully understand.

Exhibition Hall after lunch

Played around with a Jenkins docker instance and the new Pipeline Plugin (formerly named Workflow Plugin) at the Cloudbees booth. I had a nice short talk with Bernhard Cygan about some other Jenkins topics.

Tobias Kraft, Ralf Müller (exensio GmbH): Spock and Geb: Clear and comprehensible tests

This is an interesting combination of frameworks for human readable behavior tests. I’m not sure if it is really enterprise ready (do you use version 0.x?). Will this work with Oracle ADF development too? Have to check this as next opportunity.

Sven Ruppert (Macros Reply): Practical mutation testing

This seems to be the long searched key to find the right tests on the corner cases of our applications. I have mandatory to prove the mentioned PIT framework Very charismatic and tough presenter.

Roel Spilker (TOPdesk), Reinier Zwitserloot ( Lombok: The Boilerplate Buster. It’s a Kind of Magic!

Is this the way to hide generated and framework required code, like standard getters and setters, from the really interesting code, which implements my requirements? It is implemented as a java compiler plugin. Have to check immediately, if this will work with Oracle JDeveloper too. In Eclipse the structure shows the code of generated class, which contains the generated boilerplates via the lombok framework annotations. And what changes are required to fulfill now my static code analysis rules which work on the source code. Additional this was a very entertaining presentation.

Bert Jan Schrijver (JPoint): Continuous Performance: Automated Load Testing with Gatling

As our PoC of JMeter was not really satisfying especially for maintenance of test cases and the load testing should not cost anything at least at the moment, we should definitely this opensource tool a try. Especially the combination of the recorder and the presenter converter scripts to java looks promising. Maybe we could reuse the page object locators from our Selenium tests?

Hubert Klein Ikkink (JDriven): Writing Documentation with Asciidoctor Is Awesome

Focus on content instead of formatting in your documentation! With this tool it seem to be possible to really versioning and therefore to diff your documentation between commits. And still you can generate via templates modern output formats e.g. like HTML 5 or PDF. With a clever combination of features you can annotate your code with markers, to reuse this actual code between this markers in your documentation. And via ASCII art you can generate simple diagrams too. I will absolutely try this on my private projects soon.

Community Hall – Meet the libs

The motto was: show me your favorite opensource lib and I show your mine:

Sven Ruppert again – Proxybuilder: Change the behavior of deep code for different purposes of CDI eg. Metrics, Logging or testing. Maybe interesting for my future tests.
Roland Huß – Jolokia: JMX Bean access via JSON over HTTP, interesting but don’t know if I ever need this
? – Asciidoctor again: Jump additional over some of tool integrations
? – Keycloak: If I ever need a SSO or IDM solution for my private projects this will the first citizen in my tool chain.
? – Wildfly swarm: Interesting but actually I did not touch JBoss or Wildfly in my projects.


Generally very good food, I had not expected this here. At dinner I meet at my desk with some staff of canoo, which set up the voting machines at Javaland too. Nice and diverting talk, thank you guys!

That’s it!

Fix code editor save actions in JDeveloper 12.1.3: keep the order of actions


If you work with JDeveloper 12.1.3 and you work with code editor save actions the order of actions could be relevant for you. For an example you use lot of asterisk (*) imports and JDeveloper should edit the code to import only classes that you actually use in the code.

For an example you have entered following save actions and hit ok


After reopen the preference dialog you see that the order has be changed:



But no problem, there exist Patch 19434883: ORDER OF CODE EDITOR SAVE ACTIONS ARE NOT SAVED CORRECTLY.

Remember to install the patches for all of your developers!

Remember too, if you want to install more than one patch, there can be conflicts. Please test carefully, if all of your problems are solved for all patches after adding one more patch. Maybe you have to create a merge request in Oracle My Support.

That’s it!

Fix completion insight in JDeveloper 12.1.3: show return type again


If you work with JDeveloper 12.1.3 you may missing the return type of methods in completion insight.

For an example you hit CTRL-SPACE after following code


you see that at the start and at the end of the popup the available method names and parameter. If you have worked before with older versions of JDeveloper, you know that there is shown the return type of the method at the end. What a loose of productivity!

You run into Bug 19353293 : CODE INSIGHT : RETURN TYPE NOT SHOWN.

But no problem, there exist patch 19353293: CODE INSIGHT : RETURN TYPE NOT SHOWN, which solves the problem for you:


Remember to install the patches for all of your developers!

Remember too, if you want to install more than one patch, there can be conflicts. Please test carefully, if all of your problems are solved for all patches after adding one more patch. Maybe you have to create a merge request in Oracle My Support.

ADF Archtitecture Practice – JDeveloper Silent Install of Extensions

This article describes how to standardize your JDeveloper Installation as requested in Planning & Getting Started – Team, Skills and Development Environments. It is part of the ADF Architecture Practice lessons and describes the installation with examples for windows.

Version 12.1.x

There is a tool ojwebupdate to handle this. It is fully supported but it’s not documented at the moment, documentation is planned for 12.1.4. But you can get a lot of info, if you call:

ojwebupdate /?

The easiest thing is to download your reqired extension from the update centers. The update centers can be updated too, so the best thing is to call “Check for updates” in a manual installation and then look in your JDveloper system directory for a file updatecenters.xml.

Eg. if you want to install the extension “JUnit Integration” for version 12.1.3 in Windows 7 you have to go to the url, which is listed under “Official Oracle Extensions and Updates” by default in file

C:\Users\[Your User]\AppData\Roaming\JDeveloper\system12.\o.ide\updatecenters.xml

At the moment this is Open this link, follow the link to “JUnit Integration” and download the required version. The right version can be determined by checking the requirement against your JDeveloper version or other extensions, you can find this information in the Help – About dialog. Or easier – you look at version, which version the manual installation would be installed and download this.

Then you can call installation with following batch file:

set oracle_home=C:\Oracle\JDev121300
%oracle_home%\jdeveloper\jdev\bin\ojwebupdate -zips=[Path]\

Extensions can be depending on another extension, you see this in the requirements section of theurl or when you try to install a single extension in a fresh manual installation. In this case you have to install the extensions in the right order.


Version 11.1.1.x
The downloading of the file is similar to above, for version you should download “JUnit Integration” extension at the moment from

You can simply unzip the extensions into your installation. The target depends from the extension itself. Therefore open the zip file and look into the META-INF\bundle.xml file. If there is a tag , then this is the target. If this tag does not exist, the default target is %oracle_home%\jdeveloper\jdev\extensions.

The following batch will install “JUnit Integration” and “JUnit Integration for JDBC” extensions in the right order (as the second requires the first) in JDeveloper

set oracle_home=C:\Oracle\JDev111170
unzip -o -q junit_bundle -d %oracle_home%\jdeveloper
unzip -o -q -d %oracle_home%\jdeveloper\jdev\extensions
rem housekeeping
rmdir /S /Q %oracle_home%\jdeveloper\META-INF
rmdir /S /Q %oracle_home%\jdeveloper\jdev\extensions\META-INF

That’s it!

ADF Archtitecture Practice – JDeveloper Silent Patch

This article describes how to standardize your JDeveloper Patching as requested in Planning & Getting Started – Team, Skills and Development Environments. It is part of the ADF Architecture Practice lessons and describes the patching with examples for windows.

Version 12.1.x

In this version  the Oracle OPatch is delivered with the silent installation of JDeveloper.

All what you need is the patch file for your platform (e.g. for JDEVADF SECURITY PATCH UPDATE CPUOCT2014). Unzip this patch file.

Then you call batch file similar to:

set oracle_home=C:\Oracle\JDev121300
pushd [path]\19591087
%oracle_home%\OPatch\opatch apply -silent

Revert the patch is similar, the response should look like

set oracle_home=C:\Oracle\JDev121300
pushd [path]\19591087
%oracle_home%\OPatch\opatch rollback -id 19591087 -silent

In Line 3 you have to enter the patch number, which has to be reverted after -id.

Version 11.1.1.x
In some of this versions Oracle OPatch is not delivered with the silent installation of JDeveloper. Please check if %oracle_home%\oracle_common\OPatch does exist. If not – you can download the latest version of OPatch here. Please select your Platform and Release  as this correspond to your JDeveloper version. Unzip the downloaded file.

In some versions (at least till you need for the first patch a default product.xml file in the right place, as this cannot be created silently. Change the highlighted lines according to your environment:

<?xml version="1.0" encoding="WINDOWS-1252"?>
	<name value="SA_JDEV"/>
	<version value=""/>

For older versions of opatch maybe you have to add a response file for opatch, which you can create as described here.

Then you need the patch file for your platform (e.g. for JDEVADF SECURITY PATCH UPDATE CPUOCT2014). Unzip this patch file.

Then you call batch file similar to:

set oracle_home=C:\Oracle\JDev111170
set java_home=%oracle_home%\jdk160_24
rem opatch_home=[your unzipped OPatch home]
set opatch_home=%oracle_home%\oracle_common\OPatch
rem set _JAVA_OPTIONS="-Duser.language=en"
rem workaround for silent creation of product.xml till at least version
rem if not exist %oracle_home%\product.xml copy product.xml %oracle_home%\product.xml /V /Y
rem if not exist %mw_home%\jdeveloper\product.xml copy product.xml %mw_home%\jdeveloper\product.xml /V /Y
pushd [path]\19591087
rem use switch -ocmrf, if you have an older opatch version, which  requires a response file 
rem use switch -jdk, if you have the downloaded opatch version
rem cmd /c %opatch_home%\opatch apply -silent -ocmrf ocm.rsp -jdk %oracle_home%\jdk160_24
%opatch_home%\opatch apply -silent
rem set _JAVA_OPTIONS=
Reverting patches is similar to 12.1.x.
set oracle_home=C:\Oracle\JDev111170
set java_home=%oracle_home%\jdk160_24
rem opatch_home=[your unzipped OPatch home]
set opatch_home=%oracle_home%\oracle_common\OPatch
pushd [path]\19591087
rem use switch -ocmrf, if you have an older opatch version, which  requires a response file 
rem use switch -jdk, if you have the downloaded opatch version
rem cmd /c %opatch_home%\opatch rollback -id 19591087 -silent -ocmrf ocm.rsp -jdk %oracle_home%\jdk160_24
%opatch_home%\opatch rollback -id 19591087 -silent

That's it!

ADF Archtitecture Practice – JDeveloper Silent Install

This article describes how to standardize your JDeveloper Installation as requested in Planning & Getting Started – Team, Skills and Development Environments. It is part of the ADF Architecture Practice lessons and describes the installation with examples for windows.

Version 12.1.x

In this version  the Oracle Universal Installer allows the silent installation of JDeveloper. All what you need is the installer file for your platform (e.g. jdev_suite_121300_win64.exe) and a response file. You can create your response file as described in the documentation:

  1. Run your product’s graphical installer or installer, as described in your product installation guide.
  2. For product installation, on the Installation Summary screen, click Save Response File to save your installation parameters to a response file.

The resulting file should be look similar to the following code:


Response File Version=


#This will be blank when there is nothing to be de-installed in distribution level
SELECTED_DISTRIBUTION=JDeveloper Integrated Server Suite~

#The oracle home location. This can be an existing Oracle Home or a new Oracle Home

Then you call a command similar to:

jdev_suite_121300_win64.exe -silent -waitforcompletion -responseFile [complete path]\response.rsp

Deinstallation is similar, the response should look like


Response File Version=


#This will be blank when there is nothing to be de-installed in distribution level
SELECTED_DISTRIBUTION=JDeveloper Integrated Server Suite~

#The oracle home location. This can be an existing Oracle Home or a new Oracle Home

Then you call the deinstallation via following commands:

set oracle_home=C:\Oracle\JDev121300
rem %oracle_home%\oui\bin\deinstall.cmd -noconsole -silent
"%oracle_home%\oui\bin\internal\ilaunch.exe" -noconsole -deinstall -silent ORACLE_HOME="%oracle_home%"

Pay attention that we did not use line 2, as this exits your command shell on windows. But we want to have a return code and maybe doing some post deinstall work (Enhancement Request 19464646 is created). Instead we have looked what command deinstall.cmd generates and put this on line 3.

Version 11.1.1.x
For this version you need the generic installer (eg. jdevstudio11117install.jar) and the 32bit JDK 1.6.0_24 (this is the delivered version for the manual install, 64bit version is not supported but works for most cases but not all). First you have to extract the msi JDK Installer as described here. Then you have to create a file silent.xml which is the equivalent of response.rsp in 12.1.x.

<?xml version="1.0" encoding="UTF-8"?>
    <data-value name="BEAHOME" value="C:\Oracle\JDev111170" />
    <data-value name="COMPONENT_PATHS" value="JDeveloper and ADF/JDeveloper Studio|JDeveloper and ADF/Application Development Framework Runtime|WebLogic Server/Core Application Server|WebLogic Server/Administration Console|WebLogic Server/Configuration Wizard and Upgrade Framework|WebLogic Server/WebLogic JDBC Drivers|WebLogic Server/WebLogic Server Clients|WebLogic Server/WebLogic SCA|WebLogic Server/UDDI and Xquery Support"/>
    <data-value name="INSTALL_SHORTCUT_IN_ALL_USERS_FOLDER" value="yes"/>
    <data-value name="LOCAL_JVMS" value="C:\Oracle\JDev111170\jdk160_24\"/>

Then you can call Installation with following batch file:

set mw_home=C:\Oracle\JDev111170
set oracle_home==%mw_home%\oracle_common
set java_home=%mw_home%\jdk160_24
c:\windows\system32\msiexec.exe /i [complete path]\jdk1.6.0_24.msi /quiet ADDLOCAL="ToolsFeature,SourceFeature" INSTALLDIR="%java_home%" REBOOT=Suppress
"%java_home%\bin\java" -jar jdevstudio11117install.jar -mode=silent -log=install.log -silent_xml=silent.xml

You can call the deinstallation with following batch file:

set mw_home=C:\Oracle\JDev111170
set oracle_home==%mw_home%\oracle_common
set java_home=%oracle_home%\jdk160_24
%mw_home%\utils\uninstall\uninstall.exe -mode=silent -log=uninstall.log
c:\windows\system32\msiexec.exe /x [complete path]\jdk1.6.0_24.msi /quiet REBOOT=Suppress

That’s it!

Find problems when you develop: using XRebel with Oracle ADF

Some days before ZeroTurnaround has released XRebel , a new tool to recognized problems in your web applications, when you make your developer test.

This was promising, so I give it a short try for Oracle ADF applications. For this blog I use the Summit ADF application, delivered by Oracle, but I have tried with our own application too. Test is done in JDeveloper 12.1.2.

After the download there are some easy steps of setup to do:

First thing is to change an existing or add a new run configuration:
2014-06-30 07 09 28

2014-06-30 07 09 38

Then edit this configuration

Save the configuration by pressing OK two times.

Then open your Page and run it via the run configuration:

As First you see one time a dialog to request and enter the trial license.

Then you see the XRebel widget on the left side and after waiting some little time the first issues are shown.

From the default configuration (which can be changed with the gear in the widget) there seems a problem with the size of the session and with SQL Queries. If you drill down to the queries tab on the SQL page you see the execute queries, sorted by execution time, maybe the app should execute some of the queries at least not before changed to the tab, where it is used?

If you look at the session size, then interesting is, that most of the session size is hold on the ODL log manager. Maybe oracle should think about this result, maybe there is a better way to hold this data.

So download XRebel and give it chance on your ADF application.
