这是我的 jnlp 文件:

Here's my jnlp file:

    String protocol = request.getScheme();
    String domain = request.getServerName();
    String port = Integer.toString(request.getServerPort());
    String a = protocol + "://" + domain + ":" + port + path;
    path = protocol + "://" + domain + ":" + port + path + "/";
    String invitedUnder=request.getParameter("invitedUnder");

        <param name="invitedUnder" value="${invitedUnder}"/>
    </applet-desc>
    <update check="background"/>
</jnlp>            

我不明白出了什么问题，因为前一天一切正常.我使用的是 SpringMVC 3.2 版本和 Java 7.

I don't get whats gone wrong because the day before everything was working fine.I am using SpringMVC 3.2 release and Java 7.

推荐答案

href="" href 应明确设置为有效路径，或完全省略.

href="" The href should be explicitly set to a valid path, or omitted entirely.
