Error on creating CMP Bean

[carlos.grahl]

Hi, all

I´m using Jboss 3.0.0 (final) + MySQL.

I made a CMB Bean, deployed it, and no errors occured.

When my test program create an instance of that bean, I´ve got this error:

java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.ServerException: Internal error setting instance field codigo
Embedded Exception

The field 'codigo' is the Primary Key.

Does anybody have any idea?

TIA

The server is telling you that it got an exception while creating a ClientePK. Check the server log for more information. Also verify that the ClientePK is coded according to the EJB primary key rules. If you don't know these rules, I suggest that you don't use a custom PK. Most users don't use them, and they are very hard to code correctly, even experts have trouble (XDoclet has a bug for a long while in its custom pk generation code).
