jrun servlet错误“尝试上载多部分表单时,系统找不到指定的路径”

有些代码生产服务器上载的文件似乎已停止工作,并出现以下错误:

JRun Servlet Error 作为页面标题和页面正文中的以下内容:

500

此问题可通过以下代码复制,并在提交表单时发生。

<form method="post" enctype="multipart/form-data" action="test.cfm">
    <input type="FILE" name="frmFile">
    <input type="submit" name="frmSubmit" value="Upload">
</form>

有没有人知道是什么引发了这个问题,如何解决它,以及如何防止它在未来发生?

亲切的问候,
