Caused by: org.xml.sax.SAXParseException: Character reference "&

求教关于java调用webservice的问题
Webservice地址：http://*.*.*.*/podetailws.asmx(不好意思，由于安全问题*.*.*.*表示IP地址)

利用axis自动生成的客户端类，执行时出现下面的错误，请教是什么原因。

我查了下，是在执行远程访问的invoke（）函数时出现的“org.xml.sax.SAXParseException: Character reference "&#0" is an invalid XML character，”错误。
请问可能是什么原因？该如何解决，感激不尽。谢谢。

我的QQ是4784182，欢迎加我的QQ互相交流。



[解决办法]
org.xml.sax.SAXParseException: Character reference "&#0" is an invalid XML character，
应该是解析的时候出错。
首先，
&#0少了个分号，不过即使加上那个分号通过Unicode转码也转换不出东西。应该是个不合法的字符。你应该看下你的Webservice地址（应该是个wsdl文件）那个xml文件中是否有非法字符。

org.xml.sax.SAXParseException: Character reference "&#0" is an invalid XML character
引用了"&#0"的Character 不是合法的xml字符。应该是xml格式问题。

看了你的3楼的说明，服务器端应该没有问题，他返还给你了结果的XML文件，但是你解析接收到的这个结果的时候出错了。

我对这个不是很精通，也只能帮你找找问题所在却提供不出解决方法。你自己写客户端代码试试看，或者主动处理一下xml文件中的这些�

如果解决了希望共享下解决方法..
