java.io.IOException: Attempted read on closed stream.

尝试读取关闭流。

出现这种情况，一个原因可能是 把客户端与服务端的连接对象关闭了 或是 清空了。

ServiceClient sender = getSender();

sender.setOptions(webTest.buildOptions("getCarsList"));

OMElement result = sender.sendReceive(webTest.buildParam("getCarsList"));

// sender.cleanupTransport();

return result.toString();
