hello i am trying to use drools on a windows 2003 server... (not my choice, but hey :) on on tomcat 6 i deployed drools 5.2 and oryx designer. 1. the oryx designer does not work properly (i can put objects on the drawarea but i can not use any other functionality, see example) 2. and integration in guvnor does not work. (1.) When for example i try to do "show BPMN 2.0 DI XML" in designer it displays the error: Oryx: An error occurred while generating the BPMN 2.0 DI XML Serialization. ==> INFO 05-08 11:27:02,426 (NilAuthenticator.java:authenticate:35) All users are guests. javax.xml.bind.PropertyException: name: com.sun.xml.bind.namespacePrefixMapper value: de.hpi.bpmn2_0.transformation.BPMN PrefixMapper@11f5ff9 at javax.xml.bind.helpers.AbstractMarshallerImpl.setProperty(AbstractMarshallerImpl.java:338) 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:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) 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.Http11AprProcessor.process(Http11AprProcessor.java:864) at org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:579) at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1665) at java.lang.Thread.run(Thread.java:662) (2.)
