DeploymentException - could not create entity - NullPtrExcep

baryiames May 9, 2003 7:00 AM

Deploying this EJB is becoming hazardous to my health!!!
Has anyone seen a null ptr exception while deploying entity beans on 3.2.1?
This is killing me since the bean is so simple... gotta be obvious...

This is a pointbase db, configured with a -ds file. It is the default datasource
having replaced hsql entirely. The db is working since I see the connection pool
bring up the right number of connections, and JMS has configured itself properly
with its table creation. I've tried adding resource manager configs to the
xml files w/o success for the datasource.

Thanks for the help

davidjencks May 10, 2003 6:29 AM (in response to baryiames)

I think you should ask on the persistence forum, I'm not an expert in the cmp2 config. I suspect that something is missing for the entity commands in the standardjboss-cmp2-jdbc.xml (??name) file for pointbase. However this is certainly not an informative or appropriate notification of that:-)
