Hi there, 

I am trying load the example package mortgages with
/
KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent(
"MortgageAgent" );
kagent.applyChangeSet( ResourceFactory.newUrlResource(
"http://localhost:8080/guvnor-webapp/org.drools.guvnor.Guvnor/package/mortgages/LATEST/ChangeSet.xml"
) );
KnowledgeBase kbase = kagent.getKnowledgeBase();/

the execution of the "applyChangeSet" produces the error:


/java.lang.RuntimeException: KnowledgeAgent exception while trying to
deserialize KnowledgeDefinitionsPackage  
	at

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

My development environment:

Server:
  Apache Tomcat  6.0.26
  Guvnor server Version 5.2.0.Final

Client:
  Eclipse 3.5 Galileo
  Java jre6
  mvel2.jar version 2.0.19
  drools-api.jar Bundle-Version: 5.2.0.SNAPSHOT
  drools-core.jar Bundle-Version: 5.2.0.SNAPSHOT


Thanks in advance.
