@Version and DescriptorException [message #760320]

I have an entity called Foo with an embedded class Boo. Both classes are declared in my persistence.xml. Boo is packaged in different jar than Foo. Foo is packaged in an EJB jar; Boo is packaged in an utility jar (app-inf/lib). Boo has a timestamp property.

Both jar are deployed and run successfully.

When I put @Version on timestamp property of Boo, I get following exception:

Exception [EclipseLink-93] (Eclipse Persistence Services - 2.1.3.v20110304-r9073): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: The table [FOO] is not present in this descriptor.
Descriptor: RelationalDescriptor(Foo --> [DatabaseTable(FOO)])

If I package Foo and Boo in the same ejb jar, this exception is not shown.

Thanks for any help.

I'm back to this problem.

The problem happens only if I have two classes containing another one embedded and the embeded class has @Version property.
Foo is the Embedded class
Boo is one off the class that declares Foo
Doo is the other classe that declares Foo

The first time time I try to run the aplication I get the following exception:

Caused by:(5) org.eclipse.persistence.exceptions.IntegrityException

When I take the annotation @Version of Boo the problem disapear.
When just one Entity declares Boo the problem disapear too.

This error does not occur if you package both classes in the same jar?
That is odd, please include your persistence.xml file.

It DOES happen even packaging all classes in the same jar.
I've just checked, the problem happens even if all classes have the same package (qualified name).

But you said in your first post,

>> If I package Foo and Boo in the same ejb jar, this exception is not shown.

So, that was false?

Try the latest release, this may have been something that was fixed. Otherwise log a bug, it seems like the version field is not getting initialized correctly.
