Deployment Failed: Error Parsing XML

Hello Activiti community,

I am developing a BPMN process in Activiti. Whenever I add a signal definition to my process or leave the "collaboration" tag inside the XML file, I am getting a "Error Parsing XML" message.

Here is what I mean:

<blockcode>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:omgdc="http://www.omg.org/spec/DD/20100524/DC" xmlns:omgdi="http://www.omg.org/spec/DD/20100524/DI" typeLanguage="http://www.w3.org/2001/XMLSchema" expressionLanguage="http://www.w3.org/1999/XPath" targetNamespace="http://www.activiti.org/test">

  <signal id="correctionDone" name="correctionDone"></signal>

  <collaboration id="Collaboration">
    <participant id="klausurstellung" name="Klausurstellung" processRef="klausurstellung"></participant>
  </collaboration>
 
<!– process –>
<!– the signal is  further defined within the process –>
</blockcode>

If I delete both, the collaboration tag and the signal definition inside of my BPMN diagram. The process deployment works.

This is the error stack trace:

I have checked the forum and added the cxf dependencies to my Tomcat/lib folder.

Thanks in advance,
