when I new a JPA project, select the platform, only 1.x is shown, why?
the sequence is attached as image 1-5.
In step 2, I select weblogic 11g as runtime, in step 3, I select default configuration for weblogic 11g, then in step 5, no eclipse 2.x is allowed to choose.

I know weblogic 11g (10.3.4) default is using jpa 1 but can manual enable to support jpa2, and I already manual enable it. But dali still not allow me to choose eclipselink 2.x in step 5, why?

Have you tried to click the "Modify..." button seen in screen shot 2 to change the JPA facet version to 2.0? By changing this setting, you should then be able to see the EclipseLink 2.x platform in step 5.

as shown in attachment 3.jpg, click modify button, there is only three choice without "JPA facet version to 2.0".
the three choice shown in 3.jpg is
"default configuration for oracle weblogic server 11g..."
"Minimal Configuration"
"Minimal JPA 1.0 configuration"

You need to actually click the "Modify...' button, as opposed to selecting one of the preset configurations in the drop down.

sorry, I am very new to Dali and eclipselink.
After press the modify button, jpa6.jpg is shown, and there is still no jpa 2.0 to choose.
jpa7.jpg shown my current dali version.

in the link
http://docs.oracle.com/cd/E21764_01/web.1111/e13720/using_toplink.htm#CIHDGHFE
weblogic 10.3.4 should support jpa 2.0 after manual install the patch.

2)
if choose tomcat 6.0 as the target runtime as shown in jpa8.jpg, then in platform (jpa9.jpg), I can choose Eclipselink 2.0.x, and in JPA Implementation, I need download Eclipse 2.1.3 if my eclipse version is Helios?

3)
Any tutorial for learning EclipseLink + Dali + JPA recommended?

You actually need to change the version on the config screen in jpa6.jpg. It's a dropdown. This is separate from the manual enablement you've done to WebLogic. This tells the UI that you want to develop a JPA 2.0 compliant application.

See Paul's comment regarding the version field. You are correct that WLS 10.3.4 will support JPA 2.0 after patching.

2) You should probably be basing your tooling needs around the version of EclipseLink that you need to use. Is there a reason you cannot move beyond the Eclipse Helios version? Helios is getting pretty old at this point.

3) The Dali website links to a number of How-To demos and also has a tutorial that may be helpful. The tutorial is somewhat out of date, but the concepts should be the same. Look on the right hand side of the screen for link to documentation, etc. http://eclipse.org/webtools/dali/

OK...I have reproduced this problem first hand and see the issue you are describing. Please take a look at the following blog post. I think following the contained instructions will solve the issues you are having.

I should add that the WLS server adapter was limiting the JPA choices based on the original 10.3.4 support. It sounds like this can be changed based on the above link.

I have just followed the instruction in
https://blogs.oracle.com/gstachni/entry/using_jpa_20_with_weblogic_ser
but then when I new a JPA project and press modify in configuration, the JPA version is still 1.0 and cannot be changed (not shown as a dropdown list)

WLS 10.3.4 does not support JPA 2.0 out of the box. It needs to be modified to provide that support. The blog instructions that you've followed make that modification, but it looks like something is going wrong if you are still not able to select that version of JPA facet.

What does the screen referenced in the blog look like now? Please attach a screen capture. Also attach a screen capture of the facets selection screen with the runtimes tab on the right selected and the weblogic server that you are targeting selected. I'd like to see what is listed in the yellow box beneath the runtimes list.

1) What does the screen referenced in the blog look like now? Please attach a screen capture.
as attached in jpa11, jpa12, jpa13AfterInstall, in jpa13AfterInstall, although already press the server extension by clicking the install link, the link still appear and active.

2)attach a screen capture of the facets selection screen with the runtimes tab on the right selected and the weblogic server that you are targeting selected
as shown in jpa14.jpg, no jpa 2.0 is observed in the list.

Based on jpa13AfterInstall.jpg, I see that JPA 2.0 install is failing. Take a look at your Error Log view to see if there is anything interesting. You may also want to make sure that your WLS install folder is writable by whatever user you are running Eclipse under.

where is the error log view? I try to search *.log in weblogic installation folder but cannot found any relevant *.log file.
I am sure the WLS install folder is writable by the login user.

I am referring to Eclipse Error Log view. Find it via Window -> Show View -> Other -> General -> Error Log. If you haven't used this view before, it will likely be littered with a lot of unrelated content. Clear its content and then try JPA 2.0 install again. What do you see?

Make sure that the server isn't running when you do this and that nothing else is locking weblogic.jar or making it unnaccessible. Try renaming weblogic.jar. Did that work?

If you keep having problems with this, you may need to reinstall WLS.

I think success this time according to jpa15.jpg.
I need delete the WLS in eclipse first, then restart eclipse, add WLS in eclipse, and while adding, click the Install link for Java Persistence 2.0.

I check in window explorer, weblogic.jar and oepe-contributions.jar is updated.

But I want to ask, if I don't manually modify the commEnv.cmd in WLS\common\bin as mentioned in
http://docs.oracle.com/cd/E21764_01/web.1111/e13720/using_toplink.htm#CIHDGHFE
and just follow the procedure in
https://blogs.oracle.com/gstachni/entry/using_jpa_20_with_weblogic_ser
will the weblogic 10.3.4 provide support for jpa 2.0?

thanks for all reply

If you use Eclipse to add JPA 2.0 support to WLS, you do not need to follow commEnv.cmd instructions which provide an alternate way of doing this that isn't compatible with Eclipse.
