java调用webservice接口?报错

最近做个项目,要用java调用webservice接口,写个测试类就报错了,求大神指点,以下是代码及错误信息:

try {
            String endpoint = "http://www.xdz.gov.cn:8080/system/services/UserService?wsdl";
            //直接引用远程的wsdl文件
            Service service = new Service();
           Call call = (Call)service.createCall();
           call.setTargetEndpointAddress(new URL(endpoint));
            call.setOperationName("userLogin");//WSDL里面描述的接口名称
            call.addParameter("servicesuserinfo", org.apache.axis.encoding.XMLType.XSD_STRING,
            javax.xml.rpc.ParameterMode.IN);//接口的参数
            call.addParameter("useraccount", org.apache.axis.encoding.XMLType.XSD_STRING,
                    javax.xml.rpc.ParameterMode.IN);//接口的参数
            call.addParameter("password", org.apache.axis.encoding.XMLType.XSD_STRING,
                    javax.xml.rpc.ParameterMode.IN);//接口的参数
            call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);//设置返回类型  


            String result = (String)call.invoke(new Object[]{PwdCrypt.encrypt(encode),"admin",PwdCrypt.encrypt("!2@:?+)JUXDZ^%&*")});
            //给方法传递参数，并且调用方法
            System.out.println("result is "+result);
     }
     catch (Exception e) {
            e.printStackTrace();
     }
异常信息如下:
