使用k-Soap从Android的Callin Java webservice出错

概述我在 Java中创建了一个简单的登录Web服务,我从 Android代码中调用它.我将两个字符串参数传递给Webservice.但它们在Webservice中变为null. WebService Code : public boolean authenicateUser(@WebParam(name="username")String username, 我在 Java中创建了一个简单的登录Web服务,我从 Android代码中调用它.我将两个字符串参数传递给Webservice.但它们在Webservice中变为null.

WebService Code :         public boolean authenicateUser(@WebParam(name="username")String username,@WebParam(name="password")String password) {                System.out.println("InsIDe Authenticae USER+=========="+name+"-----"+Password);//This becomes null and null                 final String LOGIN_sql="SELECT * FROM UserDetails WHERE Username=? and Password=?";

Web服务托管在Localhost Tomcat服务器上

AndroID Server Request :       private static String nameSPACE = "http://src.AndroIDExample.Nagesh.com/";        private static String URL = "http://192.168.56.1:8080/AndroIDLoginWS/LoginWebService?wsdl";        private static String SOAP_ACTION = "http://src.AndroIDExample.Nagesh.com/";     Systerequest=new SoapObject(nameSPACE,WebMethodname);                System.out.println("Values before calling WS"+user.Username+"------"+user.Password);                request.addProperty("username",user.Username);                request.addProperty("password",user.Password);                return request;     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(                        SoapEnvelope.VER11);                envelope.setoutputSoapObject(request);                httpTransportSE androIDhttpTransport = new httpTransportSE(URL);     androIDhttpTransport.call(SOAP_ACTION + WebMethodname,envelope);                    System.out.println("INsIDe InvokeLoginWS==========RETURNED.................");                    SoapPrimitive response = (SoapPrimitive) envelope.getResponse();                    loginStatus = Boolean.parseBoolean(response.toString());

我是AndroID和Creating Web Service的新手.我尝试了很多其他解决方案但它似乎不起作用.

解决方法 我找到了问题的解决方案.我从wdsl打开了xsd架构.虽然我已经给出了@WebParam注释,但它只有arg0和arg1参数.我在请求中更改了它,参数正确传递. 总结
