Deployment NullPointerException during entity-command creati

Hi,

I get the following exception when deploying my EJBs:

The exception goes away when I remove another entity bean from the deployment descriptor.

Anyone seen this before?

Regards.
1. Re: Deployment NullPointerException during entity-command cr

I've found the problem - turns out I was missing XDoclet tags for identifying my primary key column.

Instead of raising a deployment verifier exception, a NullPointerException was raised in the guts CMP engine. This behaviour is probably a real bug that could be looked into.

Regards.
