java适用axis2调用.net的webservice时有时报错

Question

我建立了一个rest工程，里面增加了一个段适用axis2调用asmx的webservice代码。调用的是微软的exchange提供的webservice。问题是，我这个工程平时运行正常，但是偶尔会报错。然后过一段时间又好了。请各位大神帮忙分析可能性。报错时的信息如下，不用重启自己过段时间就好了。

Answer 1

    Cause: The documented ended unexpectedly, perhaps due to truncation.    Action: Verify that the document is complete.

Answer 2

org.apache.axis2.AxisFault: Server was unable to process request. 
---> The XML document ended unexpectedly.
文档未正常结束，检查下服务端返回回来的xml文档格式

Answer 3

The XML document ended unexpectedly.
建议错误的时候，执行下对应的参数看下最后的xml

Answer 4

看了，各位的回复。非常感谢。但是，这个报错的位置是axis的方法
ServiceClient client = new ServiceClient();
client.sendReceive（）
这里，我怎么才能看到这时给我返回的xml呢？

Answer 5

试试 httplook 查看每次回复的请求信息
