tomEE with OpenJPA meta class problems

[vmix <ar...@gmail.com>]

Hi,

I'm trying to get TomEE working with a default OpenJPA injected
EntityManager.  Here's the error:

WARNING - Meta class "com.blah.jpa.UserAddress_" for entity class
com.blah.jpa.UserAddress can not be registered with following exception
"java.security.PrivilegedActionException: java.lang.ClassNotFoundException:
com.blah.jpa.UserAddress_"

I thought maybe this meant that the OpenJPA needed to be pre-enhanced by my
build script, which I believe I've done now but still get the same error.

Ideas?

Thanks

Hi,

It is done here
http://svn.apache.org/viewvc/openjpa/trunk/openjpa-examples/openbooks/build.xml?view=markup

If you use maven check you generate and that it is compiled and included in
the artifact.

Aah, thank you for this clarification -- I didn't really grok the distinction
between Meta vs Enhanced classes... that explains a lot.  Now I realize
those underscore references (e.g. MyClass_) are referring to the Meta
classes, which aren't there because I never generated them.

So I found a maven task to generate the meta .java files, which I then
copied back into my project for normal compilation, followed by enhancement,
and then finally, OpenJpa code that works!

Thanks again for the very helpful tips.

hmm,

meta classes and enhanced classes are different things.

Typically you should get more classes.

A way to do it is to generated meta classes then add them to maven
src/main/java. But we often generate them in generated-sources *before* the
compilation.

Thanks... I am indeed using maven, and I have confirmed that the class was
enhanced.  I see the added OpenJpa code in the actual .class file.  But
nonetheless I get the same error from TomEE.
