I am trying load the example package mortgages with<br>

KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent(<br>
"MortgageAgent" );<br>
kagent.applyChangeSet( ResourceFactory.newUrlResource(<br>

) );<br>
KnowledgeBase kbase = kagent.getKnowledgeBase();/<br>

the execution of the "applyChangeSet" produces the error:<br>

I suppose it is a problem with different versions of any library, but I do<br>
not know which one, I think I have the latest version of all libraries ...<br>

<br>
Server:<br>
Apache Tomcat 6.0.26<br>
Guvnor server Version 5.2.0.Final<br>
<br>
Client:<br>
Eclipse 3.5 Galileo<br>

mvel2.jar version 2.0.19<br>
drools-api.jar Bundle-Version: 5.2.0.SNAPSHOT<br>
