写了一段java代码，用来调用http接口，java代码用执行的时候没有问题，但把代码部署在项目中就出错。

错误出现在httpclient提交数据的阶段，错误代码如下：
- I/O exception (java.net.ConnectException) caught when processing request: Conn
ection refused: connect
- Retrying request
- I/O exception (java.net.ConnectException) caught when processing request: Conn

我在网上查了一下，说我没有关闭连接没有释放或者释放方法不对，按照这个http://www.iteye.com/topic/234759改了一下但是改了之后还是报错。
求大神指教，

[逗泥丸的平方]

所以你倒是贴代码...

调用SynchronizedUserInfo(）方法，程序运行到 httpClient.executeMethod(methodPost); 就不往下运行了，因为我输出的2222222没有输出
