Problem deploying activiti-explorer on Wildfly 8.2.0

[rahzelh]

I have a problem after deployment activiti-explorer.war from war folder on Wildfly 8.2.0.

When start page is trying to display the "Internal Server Error" message is shown on the page and in logs see:

Any idea what could be wrong?

NOTE: Activiti version: 5.19.0.2, WildFly 8.2.0 in domain configuration.

When I tested on simple Tomcat it works without any problems, but the issue is on WildFly. How can I try to fix it?

Not sure - it's been a while since i tried running it on Wildfly. … the exception doesn't ring a bell immediately, I'm sorry.
