Web服务无法调用客户端 [英] Webservice couldnot able to call client

问题描述

我正在使用jax rpc样式的Web服务客户端和服务应用程序.它工作正常，但是当我在Google App Engine中部署客户端时，客户端无法调用我的服务器应用程序.

I am using jax rpc style webservice client and service applications.It is working fine,But when I deployed the client in Google app engine.The client is unable to call my server application.

我已将我的IP地址设为静态.

I have made my Ip address static.

这是部署在应用引擎中的客户端应用代码段.

Here is the client application piece of code which is deployed in app engine.

public class HelloWorldClient{

public String main(String name,String field2) throws Exception {

    URL url = new URL("http://XXX.XX.9.2X:9997/ws/hello?wsdl");

这是我系统中已发布的服务器应用程序代码

Here is the server application code which is in my system and published

  public static void main(String[] args) {
  Endpoint.publish("http://xxx.0.x.1:9997/ws/hello", new HelloWorldImpl());

我保持防火墙处于关闭状态.这种奇怪行为的原因是什么?我什至无法在appengine日志中看到错误.

I have kept my firewall to off state.What is the reason for this strange behaviour.I even couldnot able to see the error in appengine log.

这足以使我的ip保持静态，还是应该使我的ip portforward.这两者是相同的.

Is this enough that I made my ip static or should i make my ip portforward.Is both the things are same.

推荐答案

我认为问题是您没有使用google fetch库.这是从Google App Engine发送出站请求的唯一受支持的方式

I think the problem is that you are not use the google fetch library. This is the only supported way to send outbound request from Google App Engine

我可以使用org吗? google app引擎中的apache.http.client.HttpClient?
