Our component is a web application, running under Tomcat, that calls a third party Web service that sends SMS messages, it so happens.

(我们的组件是一个在Tomcat下运行的Web应用程序，它调用发送SMS消息的第三方Web服务，这种情况确实发生了。)

The line of our code on which the exception gets thrown from is the last line in the code snippet below.

(引发异常的代码行是下面的代码片段的最后一行。)

String aggregatorResponse = null;
HttpClient httpClient = prepareHttpClient( username, password );
PostMethod postMethod = preparePostMethod( textUrl );

try {
  SybaseTextMessageBuilder builder = new SybaseTextMessageBuilder();
  URL notifyUrl = buildNotificationUrl( textMessage, codeSetManager );
  String smsRequestDocument = builder.buildTextMessage( textMessage, notifyUrl );
  LOG.debug( "Sybase MT document created as: 
" + smsRequestDocument );

  postMethod.setRequestEntity( new StringRequestEntity( smsRequestDocument ) );
  LOG.debug( "commiting SMS to aggregator: " + textMessage.toString() );
  int httpStatus = httpClient.executeMethod( postMethod );

The javadoc for SocketException states that it is

(SocketException的javadoc指出它是)

Thrown to indicate that there is an error in the underlying protocol such as a TCP error

(引发以表明基础协议中存在错误，例如TCP错误)

In your case it seems that the connection has been closed by the server end of the connection.

(在您的情况下，连接似乎已被连接的服务器端关闭。)

This could be an issue with the request you are sending or an issue at their end.

(这可能是您发送的请求有问题，也可能是问题的解决。)

To aid debugging you could look at using a tool such as Wireshark to view the actual network packets.

(为了帮助调试，您可以看一下使用诸如Wireshark之??类的工具来查看实际的网络数据包。)

Also, is there an alternative client to your Java code that you could use to test the web service?

(此外，您是否可以使用Java代码的替代客户端来测试Web服务？)

If this was successful it could indicate a bug in the Java code.

(如果成功，则表明Java代码存在错误。)

As you are using Commons HTTP Client have a look at the Common HTTP Client Logging Guide .

(在使用Commons HTTP Client时，请查看一下Common HTTP Client Logging Guide 。)

This will tell you how to log the request at the HTTP level.

(这将告诉您如何在HTTP级别记录请求。)
