Hi, I have generated the code using WSCONSUME and after modifying existing code, when I try to run the old client I got Null Pointer Exception. I generated the new client using the newly generated wsdl file and the new client works fine. I debuged more and here is the request send by old client. | POST /wipe/service HTTP/1.1 | | Content-Type: text/xml; charset=utf-8 | | Accept: text/xml, text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 | | Content-Length: 655 | | SOAPAction: "" | | User-Agent: Java/1.5.0_13 | | Host: 127.0.0.1:8080 | | Connection: keep-alive | | | | <?xml version="1.0" encoding="UTF-8"?> | <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns0="http://ips.iplabs.de/types"> | <env:Body> | <ns0:startSession> | <TSession_1> | <clientLogInfo></clientLogInfo> | <clientName>testJavaClient</clientName> | <clientVersion>0.5</clientVersion> | <errorCode>0</errorCode> | <errorMessage></errorMessage> | <localeID>de_DE</localeID> | <opID>20000100</opID> | <sessionID></sessionID> | <wipeVersion>1.1</wipeVersion> | </TSession_1> | </ns0:startSession> | </env:Body> | </env:Envelope> | The request generated by the new client is as | POST /wipe/service?datatype=JBossWSMessage HTTP/1.1 | | SOAPAction: "" | | Content-Type: text/xml; charset=UTF-8 | | User-Agent: Java/1.5.0_13 | | Host: 127.0.0.1:8080 | | Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 | | Connection: keep-alive | | Content-Length: 475 | | | | <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'> | <env:Header></env:Header> | <env:Body> | <ns1:startSession xmlns:ns1="http://ips.iplabs.de/types"> | <arg0> | <clientLogInfo></clientLogInfo> | <clientName>testJavaClient</clientName> | <clientVersion>0.5</clientVersion> | <errorCode>0</errorCode> | <errorMessage></errorMessage> | <localeID>de_DE</localeID> | <opID>10000011</opID> | <sessionID></sessionID> | <wipeVersion>1.0</wipeVersion> | </arg0> | </ns1:startSession> | </env:Body></env:Envelope | | Any information , what is going wrong here. The interface file code related to startSession is : | | /** | * This class was generated by the JAX-WS RI. | * JAX-WS RI 2.1.1-b03- | * Generated source version: 2.0 | * | */ | @WebService(name = "Wipe", targetNamespace = "http://ips.iplabs.de/") | public interface Wipe { | | | /** | * | * @param tSession1 | * @return | * returns de.iplabs.ips.types.TSession | */ | @WebMethod | @WebResult(name = "result", targetNamespace = "") | @RequestWrapper(localName = "startSession", targetNamespace = "http://ips.iplabs.de/types", className = "de.iplabs.ips.types.StartSession") | @ResponseWrapper(localName = "startSessionResponse", targetNamespace = "http://ips.iplabs.de/types", className = "de.iplabs.ips.types.StartSessionResponse") | public TSession startSession( | @WebParam(name = "TSession_1", targetNamespace = "") | TSession tSession1); | } | | and the respective implementation is as : | @WebService(name = "Wipe", targetNamespace = "http://ips.iplabs.de/types") | public class WipeImpl implements Wipe | { | | | /** | * | * @param tSession1 | * @return | * returns de.iplabs.ips.types.TSession | */ | @WebMethod | public TSession startSession(TSession session) | { | if(session != null) | { | log.debug("Start session with version: " + | return getVersion(session).startSession(session); | } | else | { | log.error("Session is null"); | return null; | } | } | | } | | Plz guide me, what is going wrong. I have to update server while mainting the compatibility between old client and server. Regards, Zeeshan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4117455#...
