我正在尝试使用Apache Commons Streaming API从excel电子表格中获取信息。我继续收到以下错误：

我的表单看起来如何：
<form action="ReportServlet" method="post" enctype="multipart/form-data">
<input type="file" name="file"/>
<br />
<input type="submit" value="Upload Report" name="upload_report_btn" />
</form>
我正在使用glassfish。有什么想法，我继续得到这个消息？
答案 0 :(得分：0)
在你的循环中，你似乎假设第一个也是唯一一个到达的多部分对象将是电子表格文件。表格本身也会出现。线索是消息
Unable to read entire header; 13 bytes read; expected 512 bytes
注意，表单的上传值为Upload Report，恰好是13个字节。
如果您使用基于浏览器的调试工具（如Firebug或Fiddler），您可能很容易看到这一点。其中一个工具应该在您的工具集中。
