Hi,<br><br>I am following below article to call drools server with a client. I met a Marshaller issue.<br><br><a href="http://www.plugtree.com/?p=469">http://www.plugtree.com/?p=469</a><br><br>I found that <a href="http://www.jboss.com/products/rules/drools-api/apidocs/org/drools/command/BatchExecutionCommand.html" title="class or interface in org.drools.command">BatchExecutionCommand</a> is changed to BatchExecutionCommandImpl<br>
<br>when I call<br> jaxbContext = DroolsJaxbContextHelper.createDroolsJaxbContext(myDomainClasses, null);<br><br>errors happen.<br><br>java.lang.Error: Unresolved compilation problem: <br><br> at org.plugtree.drools.server.util.DroolsJaxbContextHelper.createDroolsJaxbContext(DroolsJaxbContextHelper.java:75)<br>

hmm.. I just found the answer: in camel-client.xml, make your to uri to:<br>
<br>
<to<br>
uri="cxfrs://<a href="http://localhost:8080/drools-server-app/kservice/kservice/rest" target="_blank">http://localhost:8080/drools-server-app/kservice/kservice/rest</a>"/><br>
instead of just one "kservice".<br>
<br>
And I am not sure why the kservice is written twice.<br>
