Hello, I have a simple bpel process definition: <?xml version="1.0" encoding="UTF-8"?> | <bpws:process xmlns:bpws="http://schemas.xmlsoap.org/ws/2004/03/business-process/"; | xmlns:ns="http://www.kiag.comArtifacts"; | xmlns:ns0="http://target.namespace"; | xmlns:tns="http://www.kiag.com"; | xmlns:xsd="http://www.w3.org/2001/XMLSchema"; | exitOnStandardFault="yes" | name="Starter" | suppressJoinFailure="no" | targetNamespace="http://www.kiag.com";> | <bpws:import importType="http://schemas.xmlsoap.org/wsdl/"; | location="Starter.wsdl" namespace="http://www.kiag.com"/> | <bpws:import importType="http://www.w3.org/2001/XMLSchema"; | location="bundleentry://288/cache/www.w3.org/2001/XMLSchema.xsd" | namespace="http://www.w3.org/2001/XMLSchema"/> | <bpws:partnerLinks> | <bpws:partnerLink myRole="StarterProvider" name="client" partnerLinkType="tns:Starter"/> | </bpws:partnerLinks> | <bpws:variables> | <bpws:variable messageType="tns:StarterRequestMessage" name="input"/> | <bpws:variable messageType="tns:StarterResponseMessage" name="output"/> | </bpws:variables> | <bpws:sequence name="main"> | <bpws:receive createInstance="yes" | name="receiveInput" | operation="process" | partnerLink="client" | portType="tns:Starter" | variable="input"/> | <bpws:assign name="Assign" validate="no"> | <bpws:copy> | <bpws:from> | <bpws:literal>Hello</bpws:literal> | </bpws:from> | <bpws:to part="response" variable="output"> | <bpws:query queryLanguage="http://www.w3.org/TR/1999/REC-xpath-19991116";> | <![CDATA[/tns:result]]> | </bpws:query> | </bpws:to> | </bpws:copy> | </bpws:assign> | <bpws:wait> | <bpws:for><![CDATA['PT20S']]></bpws:for> | </bpws:wait> | <bpws:reply name="replyOutput" | operation="process" | partnerLink="client" | portType="tns:Starter" | variable="output"/> | </bpws:sequence> | </bpws:process> This process contains a receive with a reply and I instantiate the output variable 'output' with "Hello". There is a wait statement between assign and reply waiting 20 seconds. I created this process with the bpel designer. I can deploy this definition and I can start this process calling the Starter webservice. But then an exception is thrown in the applicarion server: 22:44:22,057 ERROR [StartListener] could not start process instance | java.lang.IllegalAccessException: Class org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer can not access a member of class org.jbpm.bpel.sublang.def.Snippet with modifiers "public" | at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:65) | at java.lang.reflect.Method.invoke(Method.java:578) | at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:205) | at org.jbpm.bpel.sublang.def.Expression_$$_javassist_94.getText(Expression_$$_javassist_94.java) | at org.jbpm.bpel.alarm.Alarm.toString(Alarm.java:145) | at java.lang.String.valueOf(String.java:2615) | at java.lang.StringBuffer.append(StringBuffer.java:220) | at org.jbpm.bpel.alarm.Alarm.createTimer(Alarm.java:93) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:205) | at org.jbpm.bpel.alarm.Alarm_$$_javassist_1.createTimer(Alarm_$$_javassist_1.java) | at org.jbpm.bpel.def.Wait.execute(Wait.java:46) | at org.jbpm.bpel.def.Activity.enter(Activity.java:101) | at org.jbpm.graph.def.Transition.take(Transition.java:119) | at org.jbpm.graph.def.Node.leave(Node.java:383) | at org.jbpm.bpel.def.Activity.leave(Activity.java:171) | at org.jbpm.bpel.def.Assign.execute(Assign.java:55) | at org.jbpm.bpel.def.Activity.enter(Activity.java:101) | at org.jbpm.graph.def.Transition.take(Transition.java:119) | at org.jbpm.graph.def.Node.leave(Node.java:383) | at org.jbpm.bpel.def.Activity.leave(Activity.java:171) | at org.jbpm.bpel.def.ProcessInstanceStarter.visit(ProcessInstanceStarter.java:57) | at org.jbpm.bpel.def.Receive.accept(Receive.java:82) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:205) | at org.jbpm.bpel.def.Receive_$$_javassist_30.accept(Receive_$$_javassist_30.java) | at org.jbpm.bpel.def.ProcessInstanceStarter.visit(ProcessInstanceStarter.java:97) | at org.jbpm.bpel.def.Sequence.accept(Sequence.java:105) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:205) | at org.jbpm.bpel.def.Activity_$$_javassist_11.accept(Activity_$$_javassist_11.java) | at org.jbpm.bpel.def.ProcessInstanceStarter.visit(ProcessInstanceStarter.java:43) | at org.jbpm.bpel.def.BpelDefinition.messageReceived(BpelDefinition.java:109) | at org.jbpm.bpel.integration.jms.StartListener.onMessage(StartListener.java:115) | at org.jboss.mq.SpyMessageConsumer.run(SpyMessageConsumer.java:696) | at java.lang.Thread.run(Thread.java:595) | I do not know why this wait statement causes this exception.
A second question: I have changed the bpel process several times and have deployed the definition each time. Is it necessary to restart the application server each time? I have recognized that the changes have not taken effect after the deployment. The behaviour was different only after an additional restart of the application server . My environment: jbpm-bpel-1.1.Beta2.zip Many thanks in advance, Frank View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4002473#4002473 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4002473 _______________________________________________ jboss-user mailing list [email protected] https://lists.jboss.org/mailman/listinfo/jboss-user
