I followed the steps of this post JBPM Guvnor- TOMCAT Integration  to set up and run JBPM Designer. The only difference is that I am using jbpm-designer-2.3.0.Final-tomcat.war.

The problem that I faced is that I cannot see the run simulation button. I can see only the process paths button. What should I do to make the "run simulation" button visible?
