title: Process Engines for BPMN 2.0
body: <p>I'm doing a comparison among all existing BPMN 2.0 Process Engines e.g. Activiti, jBPM etc.
  I've prepared a list of 4 process engines which executes BPMN 2.0 given below;</p>
  
  <p>Popular BPMN 2.0 compliant open-source engines:</p>
  
  <pre><code>Activiti: http://www.activiti.org/
  jBPM: http://www.jboss.org/jbpm
  Bonita: http://www.bonitasoft.com/
  </code></pre>
  
  <p>A commercial engine:</p>
  
  <pre><code>ActiveVOS: http://www.activevos.com/products
  </code></pre>
  
  <p>I would appreciate your help if you enhance my research by adding any existing Process Engines (for BPMN 2.0) in the above list along with the quick comparison among all.</p>
  
  <p>I would prefer a very short comparison listing only important features (distinguishing features like what is possible for one and not for others, licensing, dependencies with other products like tomcat &amp; JBoss and operating systems etc)</p>
  
  <p>P.S: I've found much on Activiti vs jBPM but still your answers will be a favor.</p>
