BMP and java.rmi.ServerException

[ben]

Hi,

I'm using JBoss 2.2.2, Interbase 6.0 and BMP. The first time, I run my client-program after my bean was deployed everything works fine. When I try to run the client the second time, I get the following exception whereas the client execute the line BeanHome.create(...):

java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.ServerException: Exception occurred; nested exception is:
javax.ejb.EJBException
java.rmi.ServerException: Exception occurred; nested exception is:

The ejbCreate puts all values into the database, closes the PreparedStatement and the connection. Can you help me? Thanks.

I get the connection to the database in every method I want to execute a SQL-Statement. The first time i run the Client the test works, but when i run the client again, the listed execption occures.

Please help me, to find the fault.

Thanks

Ben
