求助发送到远程机器xml:Premature end of file错误

[herofour444]

读取本地xml文件然后，发送到远程 NC系统中。
原始代码： 需要用到dom4j.jar

本地XML文件：

<?xml version="1.0" encoding='UTF-8'?>
<ufinterface account="0001" billtype="bsmeasdoc" filename="" isexchange="Y" proc="add" receiver="K01" replace="Y" roottag="" sender="001" subbilltype="">

</billhead>
</bill>
</ufinterface>



打印结果：
<resultcode>-31003</resultcode>
<resultdescription>从输入流转换document出错：请检验文档格式。\n</resultdescription>


后台提示:
[Fatal Error] :-1:-1: Premature end of file.

整理了一下代码，并且重新在eclipse 里面新建了一个xml，结果错误依旧

这些xml手工在nc下面导入没有问题
