you are mixing incompatible hibernate, hibernate-tools and hibernate-annotations jars.

Hi,

Was this ever fixed? Iam running into the same problems:

Hibernate core 3.2.2 GA
Annotations: 3.3.0.GA

I have followed the compatibility matrix: http://www.hibernate.org/30.html

Please let me know.

the same answer applies to yours.....use compatible jars.

Hi Max,

Thanks for the reply. Like I said in my post Iam following the compatibility matrix.
Is there somewhere else you want me to look ?
Please let me know what are the compatible jars?

My setup:

Hibernate core 3.2.2 GA
Annotations: 3.3.0.GA

I have followed the compatibility matrix: http://www.hibernate.org/30.html

Thanks,

Vamsi

I don't can't see how you can be using the latest jar since you would only get an error about accessing that field if you are using an old version.

Plese double check you don't have other jars loaded first with older versions.

Hi Max,
Nope, I only have the above mentioned jar files on my classpath. Iam using both annotated files and hbm.xml files, dont know if thats causing any problems.

Thanks.
Vamsi

If you truely beleive this then please create a *small* testapp that doesn't do anything but start hibernate via AnnotationConfiguration (no spring or other code) and make it fail with just those jars in classpath.

If that still fails please report a bug against that compability matrix in our Hibernate Annotations JIRA

I have the same problem using Hibernate 3.2.2 GA, Annotations 3.2.1 GA and EntityManager 3.2.1 GA. According to the compatibility matrix these are compatible.

I only have this IllegalAccess problem when I deploy a webapp in a ear. If I deploy just a webapp, this error does not occur.

Any thoughts ?

the answer is the same.

prove it by running a simple standalone app that launches hibernate only with hibernate code in it and submit it to jira.
