I'm tryin to generate a EJB 3.0 Entity Bean on the fly, and then add it to an Ejb3Configuration instance using the method addAnnotatedClass(Class clazz), using this steps:

1- Initialize the application (in this point the application initialize a new Ejb3Configuration with no entity beans).

2. The Application generates the source code for a new EntityBean an then compile it.

3. I get the new Entity bean class and create a new Instance.

4. Add the new generated entity bean to the Ejb3Configuration.

When i try to add the generated class a get this:

java.lang.TypeNotPresentException: Type javax.persistence.Entity not present
......
......

the i can see:

Caused by: java.lang.ClassNotFoundException: javax.persistence.Entity
16:53:27,234 ERROR [STDERR] at java.net.URLClassLoader$1.run(Unknown Source)

its really strange, because i have all the nessesary libraries in my classpath, indeed it works ok if the EntityBean is not generated on the fly.

thanks in advance for any reply

you're generated class has a broken classloader
