NoClassDefFoundError during deployment

sfarkas Jul 10, 2002 11:58 AM

I had an EJB deployed with CMP & CMR in Jboss 3.0

It was working with my client. However, I added a
few more fields to the EJB and it's table.

I thought I had made all the proper changes to
jbosscmp-jdbc.xml & ejb-jar.xml, but upon deploy
I get a class not found error.

The error trace doesn't mention which 'class' isn't found!?!!!

I've retracted my steps back and removed the fields
I added to the bean - with no luck. I've rechecked the xml several times.

Anybody seen this before !? Do I debug/modify
the code to give me more information !?

argh.

Update.

We've noticed that the class not found error (during
the createEntityContainer() code as per
my original note) occurs shortly after
a "sealing violation" on a jar ?

A redeploy of the jar, to hopefully correct
the sealing violation results in the class not
found errors for any EJB - including the gangster
CMP examples !

Hmm. Judging by the lack of responses, this is
only happening to us!?
