Description of problem:

Certain scenarios in dashbuilder causes a classloading error (java.lang.NoSuchFieldError: org/apache/log4j/Level.TRACE) to arise due to a missing/mismatch log4j file. WAS8 contains a different log4j version than the BPMS application is compiled against.

To work around the issue
a) copy the log4j file
from `./business-central.war/WEB-INF/lib/log4j-1.2.16-redhat-2.jar`
to `./dashbuilder.war/WEB-INF/lib/log4j-1.2.16-redhat-2.jar`
b) configure the Dashbuilder.war file to have parent last classloading

Version-Release number of selected component (if applicable):

JBoss BPMS 6.0.2 GA on WebSphere Application Server 8.5

How reproducible:

100%

Steps to Reproduce:
one scenario is a misconfigured datasource (jdbc/dashbuilder) but other scenarios are likely.
1. Deploy Dasbuilder on top of WAS 8
2. Do not create the jdbc/dashbuilder datasource
3. Start the application container / app
4. log into dashbuilder

• • NOTE this happened in a environment with SSO configured. This should be reproducable through the steps above alone, but alternative reproduction methods may need to be found.

Actual results:

Exception in "additional info" arises.

Expected results:

No exception mentioning missing class.
