Hi there, Does any body know how to create a new task on a JBPM flow using the "Task" sample that comes when you download jbpm-bpel? I've already deployed the webservice on my JBoss server, and when I try to test it everything seems to go fine, but when I get back to the Jbpm Console and try to start the new task I got the next Error: Error loading task: An exception of type "java.lang.NullPointerException" was thrown. Error starting task: The task instance value is null My soap client has the following structure: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:task="http://jbpm.org/examples/task" xmlns:add="http://schemas.xmlsoap.org/ws/2004/08/addressing"> <soapenv:Header/> <soapenv:Body> <task:createTask> <!--You may enter ANY elements at this point--> <add:Address>?</add:Address> <!--Optional:--> <add:ReferenceProperties> <!--You may enter ANY elements at this point--> </add:ReferenceProperties> <!--Optional:--> <add:ReferenceParameters> <!--You may enter ANY elements at this point--> </add:ReferenceParameters> <!--Optional:--> <add:PortType>?</add:PortType> <!--Optional:--> <add:ServiceName PortName="?">?</add:ServiceName> <!--You may enter ANY elements at this point--> </task:createTask> </soapenv:Body> </soapenv:Envelope> Where the "taskID" and the "tokenID" values are gotten from the data display on the jbpm-console (I mean from a process that is already started). I think that my fault comes from using values that are already used by the jbpm flow, but I can't figure it out from where should I got the "taskID" and "tokenID" values. I will really appreciatte your sugestions Christian View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4157543#...
