jboss 6 and persistence.xml file

[Bob Green]

I am using jboss 6.0.0.Final version with hibernate and I am getting the following error if I don't specify the Task class in the persistence.xml file. I don't need to do that with jboss 5, can someone shed some light to this issue.

Caused by: javax.servlet.ServletException: org.hibernate.hql.ast.QuerySyntaxException: Task is not mapped [Select t from Task as t]

TIA.

Please post the entire exception stacktrace, the contents of your persistence.xml and more details about how your application is packaged.

Please help if anyone knows why?

[Jaikiran Pai]

Is it a typo in your post, or do you really have the persistence.xml at .ear/lib/META-INF folder? If that's where you have it then it's an incorrect location. Move it to .ear/lib/persistenceUnit.jar/META-INF.

[Bob Green]

Jaikiran, thanks for your answer. The persistence.xml actually is in ear/lib/persistenceUnit.jar/META-INF directory.

[Jaikiran Pai]

Post the output of

jar -tf persistenceUnit.jar

and also the code from the Todo class.

Hmmm, looks fine to me assuming the Todo class has com.persistence.model as its package declaration. Can you post the code which accesses the entitymanager and invokes on it? Including how you get hold of the entity manager?
