Salina, I think you must be using an older version of the designer and not the one that is included in the jBPM5 installer. The "'Shown BPMN 2.0 DI XML" option is no longer existing in the new version and the way to view the BPMN2 xml of a process, you should be able to just select Source->View Source in Guvnor. Also the version of guvnor you need is either from master or download 5.2.0.M1.

Thanks.

Dear Tihomir, Thanks, I shall give a try. I created the Drools BPMN flow diagram, and can run it under Eclipse with no problem, but once I added to Guvnor, the diagram is not shown up in Oryx in Guvnor. I tried the function 'Shown BPMN 2.0 DI XML'. I got the following error. enclosed is the flow: ruleflow-mail-human.bpmn I had also tried a simple one, the same error test.bpmn javax.xml.bind.PropertyException: name: com.sun.xml.bind.namespacePrefixMapper value: de.hpi.bpmn2_0.transformation.BPMNPrefixMapper@15b08736 at javax.xml.bind.helpers.AbstractMarshallerImpl.setProperty(AbstractMarshallerImpl.java:358) at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.setProperty(MarshallerImpl.java:532) at org.oryxeditor.server.Bpmn2_0Servlet.performTransformationToDi(Bpmn2_0Servlet.java:127) at org.oryxeditor.server.Bpmn2_0Servlet.doPost(Bpmn2_0Servlet.java:78) at javax.servlet.http.HttpServlet.service(HttpServlet.java:713) at javax.servlet.http.HttpServlet.service(HttpServlet.java:806) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:857) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:636)
