Steps to Reproduce

  1. Create a case  
  2. Launch it 
  3. Select any radio button on validation screen

Root Cause



The root cause of this problem is defect or misconfiguration in the PRPC operating environment. The error indicates a likely database connectivity error.

With the diagnostic HFix-9804 installed, the log displayed that a security exception occurred during classloading from the database.


Resolution


 

There are three options that can resolve this issue:

1. Set the downgrade-untrusted-principal to false.

2. Enable "Cross Domain Security Between WebLogic Server Domains".

3. Enable "global trust between domains".
