Whenever I try to run the method deploy, that is actually using repository service to deploy the resource, it gives the following exception : javax.servlet.ServletException: Servlet.init() for servlet MainServlet threw exception org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java:160) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:793) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:702) org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:571) org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:644) java.lang.Thread.run(Thread.java:619) *root cause* java.lang.NoSuchMethodError: org.w3c.dom.Element.setUserData(Ljava/lang/String;Ljava/lang/Object;Lorg/w3c/dom/UserDataHandler;)Ljava/lang/Object;      org.jbpm.pvm.internal.xml.DomBuilder.startElement(DomBuilder.java:318)      org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Source)      org.apache.xerces.impl.XMLNSDocumentScannerImpl.scanStartElement(Unknown Source)      org.apache.xerces.impl.XMLNSDocumentScannerImpl$NSContentDispatcher.scanRootElementHook(Unknown Source)      org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source)      org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source)      org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source)      org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source)      org.apache.xerces.parsers.XMLParser.parse(Unknown Source)      org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source)      org.jbpm.pvm.internal.xml.Parser.buildDom(Parser.java:452)      org.jbpm.pvm.internal.xml.Parser.execute(Parser.java:389)      org.jbpm.pvm.internal.xml.Parse.execute(Parse.java:158)      org.jbpm.pvm.internal.wire.xml.WireParser.<clinit>(WireParser.java:284)      org.jbpm.pvm.internal.cfg.ConfigurationParser.<init>(ConfigurationParser.java:46)      org.jbpm.pvm.internal.cfg.ConfigurationParser.<clinit>(ConfigurationParser.java:49)      org.jbpm.pvm.internal.cfg.ConfigurationImpl.parse(ConfigurationImpl.java:139)      org.jbpm.pvm.internal.cfg.ConfigurationImpl.setResource(ConfigurationImpl.java:118)      org.jbpm.pvm.internal.cfg.ConfigurationImpl.buildProcessEngine(ConfigurationImpl.java:76)      org.jbpm.api.Configuration.buildProcessEngine(Configuration.java:105)      action.MainServlet.init(MainServlet.java:52)      org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117)      org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java:160)      org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:793)      org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:702)      org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:571)      org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:644)      java.lang.Thread.run(Thread.java:619) This has something to do with the jars i am using but I have searched java forums for this exception and could not find anything.
