Hi,

I am trying to install jBPM 5.4 on Tomcat 7 by following the guide mentioned in https://community.jboss.org/people/bpmn2user/blog/2011/01/21/test link.

I am able to see the login page. I have given the login credentials as krisv/krisv

I am getting below exception when click on the login button.
