Classloader, Singleton, Weblogic 8.1 sp4--HELP!

Everyone:

I have searched the forum and did not see this question answered, so I am posing it to the group. My application was successful under WebLogic 8.1 with sp2. However, we moved the application to WebLogic 8.1, sp4 and it failed to deploy properly.

When I go look at the code where the deployment is failing, it fails on the section of code that was previously worked, such as ClassEJB.getKey(). When I go looking in the method, the only line change within the method was obtaining a Singleton cacheManager object.

This is from the application logs


This is from the server log:


Could someone point me in the correct direction on solving this issue? From what I have read it appears to be a classloader issue. The Singleton class is not fully active because the application ejbs are loaded first. Therefore the Singleton class had not beeen loaded.

Is there a workaround around this issue in WebLogic? I do not face this issue in WebSphere.

Thank you in advance for taking the time to read my post.

Cheers,

Russ
