I configured rdbms security realm in the weblogic 8.1 console, using rdbmsAtnProvider.jar library in the weblogic81\server\lib\mbeantypes directory. I'm using cloudscape database and I have created the following tables: USER_SECURITY, GROUP_SECURITY, USER_GRUOP_HIERARCHY AND GROUP_HIERARCHY; associating my rdbms realm configuration to this cloudscape db. When I click on the client and group links on the bea console, I have an exception: <"RuntimeException thrown by the invoke method of the Dynamic MBean">
javax.management.RuntimeOperationsException: RuntimeException thrown by the invoke method of the Dynamic MBean
