Hello Alex, I have chosed the second alternative. I was trying to let the jbpm.bpel module to read the received SOAPMessage: <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> | <SOAP-ENV:Body> | <m:apply xmlns:m="urn:samples:loanapproval"> | <loanRequestParameters> | <firstName>Bertrand</firstName> | <lastName>Njipwo</lastName> | <amount>1000</amount> | </loanRequestParameters> | </m:apply> | </SOAP-ENV:Body> | </SOAP-ENV:Envelope> In PortConsumer.java the following lines: SOAPElement operationElem = XmlUtil.getElement(envelope.getBody()); | Map outputParts = new HashMap(); | // fill in part values | Iterator partIt = parts.iterator(); | while (partIt.hasNext()) { | Part part = (Part) partIt.next(); | String partName = part.getName(); | // get part accessor from operation wrapper | SOAPElement operPartAccessor = XmlUtil.getElement(operationElem, partName); | // create part accessor in output message | Element outputPartAccessor = XmlUtil.createElement(null, partName); | outputParts.put(partName, outputPartAccessor); | // copy operation part to output part | operPartAccessor.getValue(); | XmlUtil.copy(outputPartAccessor, operPartAccessor); | } | return outputParts; | will copy the informations of the SOAPElement operPartAcessor to the outputPartAccessor and therefore retrieve the value received from the remote service and with that value initialise the outputPartAccessor-object. But i'm falling at: XmlUtil.copy(outputPartAccessor, operPartAccessor); If i call any methode on operPartAccessor it raises a NullpointerException. That why after this call the highlighted methodes also throw the same Exception. public static void copy(Element target, SOAPElement source) { | // attributes | removeAttributes(target); | copyAttributes(target, source); | // all namespaces | copyVisibleNamespaces(target, source); | // child nodes | removeChildNodes(target); | copyChildNodes(target, source); | if (log.isTraceEnabled()) log.trace("copied element: " + source.getNodeName()); | } So copyAttributes will fail because the SOAPElement operPartAccessor has no Attributes. One question: (Which methode give the value of the operPartAccessort ? I have tried with to manipulate the operPartAccessort as DOM object by call getChildrens(), but its always fail). My question is how could i get the value true of true in the following message send by the remote server: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> | <soapenv:Body> | <validCustomerResponse xmlns="urn:samples:schufa"> | <validCustomerReturn>true</validCustomerReturn> | </validCustomerResponse> | </soapenv:Body> | </soapenv:Envelope> I have comment out the following line in PortConsumer.java: XmlUtil.copy(outputPartAccessor, operPartAccessor); so i can achieve a "cleaned" process excecution and so i can make some performance measurements during the process execution. This is a temporary solution to be able to work. After doing this i become the following message: <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> | <env:Header/> | <env:Body> | <m:applyResponse xmlns:m="urn:examples:loanapproval"> | <loanResponse> | <approved/> | </loanResponse> | </m:applyResponse> | </env:Body> | </env:Envelope> Alex why i can't copy the desired value the remote service send me in my BPEL process. Thanks once again for your help and the time you invest. Regards Bertrand View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3999710#...
