Not sure why no one has tried to help me in my previous appeal but here goes again:

Hello,

I created a very simple process in Activiti, imported it to the designer assigned some tasks and created a deployment. When I try to deploy the bar file I get the following log in catalina and I would like to know what the problem is as I do not understand the nullpointer exception thing. I get this issue with even the simplest process.

Can anyone help me?
