Hi all! Until know, i have used jpdl 3.0 ( xml schema http://jbpm.org/xsd/jpdl-3.0.xsd ) But know, i want to use the asynchron execution of nodes and therefore i must change my xml schema to jpdl 3.1. I have tried to change the processdefinition in this way: <process-definition | xmlns="http://jbpm.org/3/jpdl" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://jbpm.org/3/jpdl http://jbpm.org/xsd/jpdl-3.1.xsd" | name="activityWorkflow"> But i got an error : 14:22:47,953 DEBUG [JpdlParser] resolving schema reference publicId(null) systemId(http://jbpm.org/jpdl-3.0.xsd) | 14:22:47,953 DEBUG [JpdlParser] providing input source to local 'jpdl-3.0.xsd' resource | 14:22:48,078 ERROR [LogInterceptor] EJBException in method: public abstract de.uniSiegen.crm.server.beans.stateless.interfaces.Workflow de.uniSiegen.crm | .server.beans.stateless.interfaces.WorkflowHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException, causedBy: | org.jbpm.jpdl.JpdlException: [[ERROR] line 81: cvc-complex-type.3.2.2: Attribute 'async' is not allowed to appear in element 'node'.] | at org.jbpm.jpdl.xml.JpdlXmlReader.readProcessDefinition(JpdlXmlReader.java:163) | at org.jbpm.graph.def.ProcessDefinition.parseXmlInputStream(ProcessDefinition.java:172) | at org.jbpm.graph.def.ProcessDefinition.parseXmlResource(ProcessDefinition.java:153) | It seems as if furthermore jpdl 3.0 is used. Where can i change the xml schema???? I use the jbpm 3.1.1 starterkit. Thanks, asmo View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3999017#...
