推荐答案

依赖于Web服务。难道仅仅是RESTful的XML？ JAX-WS？ JSON？ Etc.Either方式，它应该是为呼唤与HTTP套接字，并解析响应一样简单。

Depends on the web service. Is it just RESTful XML? JAX-WS? JSON? Etc.Either way it should be as easy as calling out with an HTTP socket and parsing the response.

要创建一个Web服务按照下面的链接

REST Web服务

使用了HTTPClient

using Using HTTPClient

public static String hitService(String host, int port, String path, String postBody) throws IOException {
        HttpHost target = new HttpHost(host, port);
        HttpClient client = new DefaultHttpClient();
        HttpGet get = new HttpGet(path);
        HttpEntity results = null;
        try {
            HttpResponse response=client.execute(target, get);
            results = response.getEntity();
            return EntityUtils.toString(results);
        } catch (Exception e) {
            throw new RuntimeException("Web Service Failure");
        } finally {
            if (results!=null)
                try {
                    results.consumeContent();
                } catch (IOException e) {
                    // empty, Checked exception but don't care
                }
        }
    }
