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?

Hi,

To solve your issue, open your bpmn file in XML editor and just set isExecutable to true. It will get deployed.
