        <param name="contentType">application/pdf</param>
        <param name="inputName">fileInputStream</param>
        <param name="contentDisposition">attachment;filename="abc.pdf"</param>
        <param name="bufferSize">1024</param>
    </result>
</action>

我基本上想从服务器下载pdf文件.但是我收到以下错误:

不知道该如何解决.非常感谢某人的帮助.确实需要这样做.

Don't know how to resolve this. Would really appreciate someone's help. Really need this to be done.

推荐答案

将portletUrlType="resource"放入用于创建下载链接的<s:url>标记.

Put portletUrlType="resource" to the <s:url> tag which you use to create download link.

<s:url var="downloadUrl" action="download" portletUrlType="resource" />
