[rules-users] Drools 5.5 and jBPM 5.4 on Weblogic 10.3.4

[abhishekbiyala]

Hi,

I have been struggling to get drools 5.5 and jBPM 5.4 embedded in a weblogic
10.3.4 application. 
Seems like there is some conflict between drools and weblogic jars. But how
to resolve?

This is the exception I am getting -
