JDeveloper 10.1.3.4 on CentOS 6 x86_64

Last Thursday I formated my CentOS 5 workstation at work and reinstalled version 6 from scratch. Although we have stopped developing new application with JDeveloper 10.1.x, I still require the old jdev IDE, as existing applications need maintenance and even new features.

Making jdev 10.1.3.4 work on a 64bit Linux is discussed here , n the Darwin-It blog, to whom I own a very big thank you

Finally, I would like to offer my own piece of wisdom to whoever trying to resurrect JDeveloper 10.1 inside a new OS: Keep your paths exactly the same as the previous installation :^)

JDevelopr 10g to 11g. It's a long way to migration

Today i tried migrating a simple project from JDeveloper 10g (10.1.3.4) to 11g (11.1.1.0.1) )and the results are mostly disappointing.

A picture is a thousand words.

Migration Results

This is how the application looks today.	... and here is how it ended up after migration......

Just for the shake of complicity, I have to report the following :

• Migration finished without any exceptions being thrown at the console. The only warning message that appears when opening the project is :

  Mar 30, 2009 9:43:18 AM oracle.jdevimpl.webapp.taglib.JDevTaglibUtils _parseFail
  WARNING: Invalid TLD Location, TldUtils parse failed for URL : jar:file:/home/oracle/jdeveloper/mywork/AS400-Materials/ViewController/opt/oracle/Middleware/jdeveloper/jlib/adf-faces-databinding-rt.jar!/META-INF/databinding.tld
      

• Although attribute labels are not shown in the search page, the Attribute properties page displays them correctly.
  
• The initial JSF navigation diagram, does not display any graphic, despite the fact that I see no error ether on the message window or the console.
  

I feel like I want to complain to somebody, but I am not sure to whom.

Changing the JDeveloper IDE font size

If you are like me and wish that the JDeveloper IDE displayed using a bigger font, then thanks to Khaled from Oracle support all you need to do is shut down JDeveloper, and then add a line like the following in the file ide.properties located in \jdev\system\oracle.jdeveloper.10.1.3.X.Y.

Ide.FontSize=14

Finally start JDeveloper and you are done.

Notes

1. The actual X, Y values in the oracle.jdeveloper.10.1.3.X.Y may vary depending on your version of JDeveloper. In 10.1.3.3 X=41 and Y=57, while in 10.1.3.4 X=42 and Y = 70. Anyway the safest approach is to have a look at the Oracle IDE version in the versions tab of the JDev about box as show in the image below.
   
2. Needless to say that the same goes for SQLDeveloper. The only difference is that he file to edit is located in ~/.sqldeveloper/system/oracle.sqldeveloper.1.2.1.3213. If using SQLDeveoper version 1.5 that comes with the new JDev11g look and feel then again the file chek is .sqldeveloper/system1.5.1.54.40/o.sqldeveloper.11.1.1.54.40/ide.properties.
3. On Jdeveloper 11g the ide.properties file location is ~/.jdeveloper/system11.1.1.0.31.51.56/o.jdeveloper. Once more the actul path may be determined by looking at the Oracle IDE version from the about box.

JDeveloper OC4J Changing the language that eror messages are displayed

I have had this problem many times. During development when something went wrong with my application, all I could get after the Internal server error would be JBO:XXXX error code with numerous question marks instead of the actual error message.

Some people advised me to change the preferred language/locale of my WEB browser and make it English, so as to force the display of error messages in this language, but that didn't work either.

Today I found a remedy. Open the project properties Go to Run/Debug click edit and add -Duser.language=en -Duser.country=US in the java command line options, like I show you in the following pciture

... and that does it.

JDeveloper 10.1.3.3 JSP Compiler Errors in JSF faces

I have run into the following error while modifying JSF pages in JDeveloper 10.1.3.3 on openSUSE. While modifying the page contents using the JDeveloper editor, the page stops working when accessed from the browser and you get an Internal Server Error with a JspCompileException but nothing else. The page was still accessible from the internal JDeveloper Design editor and would complie correctly from inside JDeveloper.

A remedy that sometimes worked was to remove a few components from the page put them back and then hope it would work.

Eventually I came up with the following simple trick. Just remove all contents from ~/jdevhome/mywork/WorkSpace/ViewController/classes/.jsps and rebuild your project.

JDeveloper 10.1.3.x Screen display problems

I run into the topic on the Oracle JDeveloper forums and I thought I might keep the reference here.

A guy running JDeveloper on Windows using a laptop had serious problems with the display when the IDE tried to scroll as it was leaving visible marks. It ended up that the remedy was adding AddVMOption -Dsun.java2d.noddraw=true at the $JDEV_HOME/jdev/bin/jdev.conf file.

For anybody interested the entire thread can be found here

Stop Screen Flickering in JDeveloper 10.1.3.0.4 (SU5)

After I installed SU5 to my openSUSE Linux installation of JDeveloper 10.1.3.0.4, I run into extreme screen flickering, especially while updating JSF diagrams. Then I remembered a hint I got from Oracle support a while back while we were investigating something else. Well this did it and although I don't know if this works on Windows, I 'm putting it here for anybody in the same kind of trouble.

Open file $JDEV_HOME/jdev/bin/jdev.conf and add the following line

AddVMOption -Dsun.java2d.ddoffscreen=false

Note: JDeveloper 10.1.3.2.0 does not require this.
