小弟最近做一个Java调用WCF的测试，费了老半天的功夫，终于把Java客户端给生成了。
按照书上说的调用也没问题，可就是传不了参数，服务端接收到的参数总是Null。
我的WCF服务比较复杂，有大量自定义类型，但是我想既然客户端代理已经成功生成了，就基本大功告成了，没想到传参数又出了问题。
难道java不允许这种带自定义类型的参数的传递？求各位java老师指导直到。
我的WCF公开的服务契约时Service11012，公开一个方法叫做DoOperation。如下代码：

public class Service11012 : IService11012

    {

        public WebReturn DoOperation(WebRequest webRequest)

        {

            WebReturn webReturn = new WebReturn();

            webReturn.Result = true;

            webReturn.Code = 0;

            if (webRequest == null)

            {

                webReturn.Result = false;

                webReturn.Code = Defines.RET_PARAM_INVALID;

                webReturn.Message = string.Format("WebRequest is null");

                return webReturn;

            }

            SessionInfo session = webRequest.Session;

            if (session == null)

            {

                webReturn.Result = false;

                webReturn.Code = Defines.RET_PARAM_INVALID;

                webReturn.Message = string.Format("SessionInfo is null");

                return webReturn;

            }

            webReturn.Session = session;

            try

            {

                OperationReturn optReturn;

                switch (webRequest.Code)

                {

                    case (int)RequestCode.WSGetLangList:

                        optReturn = GetLangList(session, webRequest.ListData);

                        if (!optReturn.Result)

                        {

                            webReturn.Result = false;

                            webReturn.Code = optReturn.Code;

                            webReturn.Message = optReturn.Message;

                            return webReturn;

                        }

                        webReturn.ListData = optReturn.Data as List<string>;

                        break;

                    default:

                        webReturn.Result = false;

                        webReturn.Code = Defines.RET_PARAM_INVALID;

                        webReturn.Message = string.Format("Request code invalid.\t{0}", webRequest.Code);

                        return webReturn;

                }

                webReturn.Message = optReturn.Message;

            }

            catch (Exception ex)

            {

                webReturn.Result = false;

                webReturn.Code = Defines.RET_FAIL;

                webReturn.Message = ex.Message;

                return webReturn;

            }

            return webReturn;

        }

其中DoOperation方法的参数是一个自定义的类型WebRequest，返回值也是一个自定义的类型WebReturn。
客户端调用如下：

/**

 *

 * @author Charley

 */

public class MyJavaApp {



    /**

     * @param args the command line arguments

     */

    public static void main(String[] args) {

        // TODO code application logic here

        try {

            ObjectFactory factory = new ObjectFactory();

            SessionInfo sessionInfo = new SessionInfo();

            JAXBElement<String> str;

            str = factory.createSessionInfoSessionID("abcd");

            sessionInfo.setSessionID(str);

            str = factory.createSessionInfoAppName("JavaClient");

            sessionInfo.setAppName(str);

            DatatypeFactory datatypeFactory = DatatypeFactory.newInstance();

            sessionInfo.setLastActiveTime(datatypeFactory.newXMLGregorianCalendar(new GregorianCalendar()));



            AppServerInfo appServerInfo = new AppServerInfo();

            appServerInfo.setProtocol(factory.createAppServerInfoProtocol("http"));

            appServerInfo.setAddress(factory.createAppServerInfoAddress("192.168.6.75"));

            appServerInfo.setPort(8081);

            appServerInfo.setSupportHttps(false);

            appServerInfo.setSupportNetTcp(false);

            sessionInfo.setAppServerInfo(factory.createAppServerInfo(appServerInfo));



            DatabaseInfo databaseInfo = new DatabaseInfo();

            databaseInfo.setTypeID(3);

            databaseInfo.setTypeName(factory.createDatabaseInfoTypeName("ORCL"));

            databaseInfo.setHost(factory.createDatabaseInfoHost("192.168.4.182"));

            databaseInfo.setPort(1521);

            databaseInfo.setDBName(factory.createDatabaseInfoDBName("PFOrcl"));

            databaseInfo.setLoginName(factory.createDatabaseInfoLoginName("PFDEV"));

            databaseInfo.setPassword(factory.createDatabaseInfoPassword("PF,123"));

            sessionInfo.setDatabaseInfo(factory.createDatabaseInfo(databaseInfo));



            WebRequest webRequest = new WebRequest();

            webRequest.setSession(factory.createSessionInfo(sessionInfo));

            webRequest.setCode(30001);

            ArrayOfstring arrayOfstring = new ArrayOfstring();

            arrayOfstring.getString().add("2052");

            arrayOfstring.getString().add("");

            arrayOfstring.getString().add("0");

            arrayOfstring.getString().add("0");

            arrayOfstring.getString().add("");

            arrayOfstring.getString().add("");

            webRequest.setListData(factory.createArrayOfstring(arrayOfstring));

            WebReturn webReturn = doOperation(webRequest);

            if (!webReturn.isResult()) {

                System.out.println(webReturn.getMessage().getValue());

            }



        } catch (Exception e) {

            System.out.println(e.getMessage());

        }

    }



    private static WebReturn doOperation(Wcf11012.WebRequest webRequest) {

        Wcf11012.Service11012 service = new Wcf11012.Service11012();

        Wcf11012.IService11012 port = service.getBasicHttpBindingIService11012();

        return port.doOperation(webRequest);

    }



}

运行也没有报错，返回了 SessionInfo is null ，也就是方法已经调用成功了，只是SessionInfo的值没有传过去，不知道错在哪里呀。
