Exception occured when verifying current backend id DB2UDBNT_V8_1 Our application was running fine on WAS 5.1 server. But I have deployed the same application on WAS 6.1. Unfortunately I got an exception. The data source was properly configured and I got the connection when tested on admin console. Our application also uses the Entity Beans . The exception is : Exception occured when verifying current backend id DB2UDBNT_V8_1: javax.resource.spi.ResourceAllocationException: DSRA8100E: Unable to get a PooledConnection from the DataSource.
