[JPA] Using exclude-unlisted-classes [message #890406]

Hello,

I'm trying to use <exclude-unlisted-classes>false</exclude-unlisted-classes> so I don't have to explicitly list all my entities. But without any luck so far.

I didn't find any precise documentation about this feature, just bug #356509 which leaves the question open.

So does someone know if classpath scanning is supported at all? Or will be supported soon?
Is there something else to do than setting exclude-unlisted-classes to false?
And if it's working, is it with entities from fragment bundles too?

Any explanation or a place to look for it would be appreciated.

Hi Thomas,

Setting the exclude-unlisted-classes element to false should allow scanning to occur to detect entities and managed classes within the persistence unit bundle. Are you seeing any problems with it?

Unfortunately, support for fragments is not supported by Gemini JPA (see bug 335698), so if your problem is related to using fragments that is a different beast.

Hi Mike,

I indeed wanted to use fragments (trying to modularize my PUs, as discussed in my other post "Dynamic persistence units").
But, even with a regular bundle I don't manage to use entities not explicitly listed in my persistence.xml.

I started with a test bundle with one entity (using annotations, no xml mapping). This bundle was working.
Then I removed the "class" tag from the persistence.xml, and set the value of the "exclude-unlisted-classes" tag to "false". And it's not working anymore.

Did I miss something there?

No, you haven't missed anything. That should work. Can you enter a bug against that and I will take a look at it? Thanks. When the feature was added no test accompanied it, so we are owed a test case. I might go ahead and put one of those in as well while I am at it.

Done! Submitted bug #383784 with a test bundle.

Also, when creating this test bundle I found a very strange behavior: when the bundle includes the sources, deployment triggers an infinite start stop loop, until the bundle is uninstalled. It's happening only for PU bundles when Gemini JPA is started.

Do you know something about that or should I fill a bug for it as well?

No, I have never seen that happen. If you have a test bundle for which that occurs please do enter a bug and attach the test bundle. Thanks!

Submitted bug #384323, but it was in fact not caused by sources. It's about the absence of the persistence.xml file (side-effect of adding a <resource> section in the POM).

Ah, ok. I'll take a look at it. Thanks.
