Hi,
I hv found out the issue.I hv not added one element tag in weblogic-cmp-rdbms-xml.jar.After
adding the same the above error did not come.But when I create ear file I hv got
another exception saying the jar file mentioned is not aval in the ear file.
Below is the console output:
Gateway.jar:
[echo] creating basic ejb jar file ...
[jar] Building jar: E:\myejb\staging\Gateway.jar
[echo] ... done.
[echo] appc'ing the ejb jar file ...
[echo] appc'ing the ejb jar file ...
[java] [appc] Created working directory: C:\DOCUME~1\ram\LOCALS~1\Temp\appcgen
[java] [J2EE:160120]Error: The module, 'Gateway.jar', is declared in the
application.xml descriptor but cannot be found in the ear file.

This file builds the EAR file for the SessBean.
Invoke this file by providing the base directory of the weblogic

I'd suggest you build the CMP example that ships with WLS. Then compare
the structure of its ejb-jar with your application.
If you're still having problems, can you show me the output of jar tvf
on your ejb-jar file? It's looking for the CMP descriptor in the
META-INF directory.
