Getting "No exception handler was found for an application exception" when accessing BPM Worklist

Problem

The BPM Worklistapp used to come up, now it's not responding anymore. This is the URL we are accessing:

http://soahost1:8001/integration/worklistapp

This error keeps repeating indefinitely in soa_server1-diagnostic.log when trying to access the URL above:

We DISABLED the following setting on both "soa_server1" and "soa_server2" managed servers:

SSL Listen Port Enabled.

You will find that this is the SAME EXACT error described in this Oracle documentation troubleshooting guide in section B.2.3:

http://docs.oracle.com/cd/E25178_01/admin.1111/e10226/appx_trouble.htm

We increased the FacadeFinderBean "Transaction Timeout" on the WebLogic Console from 600 to 10000, but this did not help.


Solution

1. Log in to the EM Console

2. Expand WebLogic Domain

3. Right-click on soadomain

4. Navigate to Security > Credentials

5. Expand SOA

6. Edit the entry and modify the password to the keystore password
