OracleAS 10.1.3 missing class error

Question

Hi
When I deploy my ear file on a newly installed OracleAS 10.1.3 I get the following error. I used to deploy the same ear file on previous version of OracleAS 10.1.2 and it worked fine. Please let me know how to fix this problem.
Thanks in advance.

Mustafa,
This is just a suggestion. In OC4J stand-alone 10.1.3.0.0, you can still use the "applib" subdirectory. In other words, try removing the shared library you created, as well as any references to it in any of your deployment descriptors or OC4J configuration files and simply place all the required JARs in the "applib" subdirectory. Then undeploy your application completely -- in other words, delete all related files and directories and remove all references to it in the OC4J configuration files -- and deploy it again.
Good Luck,
Avi.
