Hi all,


I am trying a human task example with variables , and i am using this link as a refrence  https://community.jboss.org/people/bpmn2user/blog/2011/02/21/jbpm5-example-for-forms-with-variables https://community.jboss.org/people/bpmn2user/blog/2011/02/21/jbpm5-example-for-forms-with-variables

But now the thing is that when i am trying to run this i am getting following error.
