CMP Ejb not deploying

Question

Hello all,
Im running WLS 6.1 with SP3 evaluation version on Win2K Pro with Oracle
8.1.6 database.
Im new to Weblogic's deployment of EAR files. I am facing the following few
problems when i try to deply any cmp entity bean:
1. Though a common file that the EJB jar depends on, is present in the EAR
file, I get errors NoClassDefFound errors for that class. I read posts which
talk about how WLS is a bit different in this regard and that common files
will have to added separately to the classpath or bundled with the ejb jar.
However isnt that defeating the purpose of an EAR file?
2. I added the common class to the classpath in the startup script and
restarted weblogic. I get the following message on the console :
<Sep 10, 2002 10:22:55 AM BST> <Error> <J2EE> <Error deploying application
ejbDeployedCore121:
Unable to deploy EJB: Accbaladj from ejbDeployedCore121.jar:
The Container-Managed Persistence Entity EJB failed while creating its SQL
Type Map. The error was: null, Exception = null
I havent read any posts which answer this problem. I created my ear file
from scratch (compilation and ejbc of the source with the new WLS6.1 tools)
and am trying to deploy it but repeatedly failing.
3. Also could somebody point out a good online article/book/paper, which
talks about WLS 6.1 deployments of EAR files, rather like Websphere's
redbooks do about WAS?
If anybody has any idea of any of the above issues, I would be grateful if
you could mail in a reply.

Answer 1

The issues are resolved now.
1. This classpath entry problem was a bit mystifying. The manifest entry was
correct and it should have picked it up automatically. When i restarted the
server though, it started up properly.
2. The CMP problem was a bit more troublesome. I think it was because of an
incorrect datasource and connection pool properties. I used utils.Schema to
check my database connection and once i got the url and driver name
correctly it worked.
