如果我运行该特定的xhtml文件，则该文件将显示在IE中.但是刷新IE后，将显示对xhtml文件的任何更新.
If I run that particular xhtml file then its shown in IE. But any update to xhtml file will will be shown after refreshing the IE.
我正在使用Eclipse-Helios IDE，Glassfish Web服务器.预先感谢

推荐答案
MSIE确实不支持application/xhtml+xml的内容类型.该页面的内容类型应为text/html(您可以使用HTTP/Web开发人员工具验证该内容).但这应该已经通过默认的JSF/Facelets配置完成了.您似乎并未在给定代码中的任何地方覆盖内容类型.一种方法是使用<f:view> 标签.另一种方法是调用 HttpServletResponse#setContentType() 在某些网络过滤器中.或者，完全不同的是，此事之后可能是由Web服务器本身或该行中的某些代理完成的.
MSIE does indeed not support the content type of application/xhtml+xml. The page should be served with a content type of text/html (you can verify that with HTTP/web developer tools). But that should already be done by default JSF/Facelets configuration. You don't seem to have overridden the content type anywhere in the given code. One of the ways is defining it using the contentType attribute of the <f:view> tag. Another way is calling HttpServletResponse#setContentType() in some web filter. Or, completely different, perhaps it's been done afterwards by the webserver itself or by some proxy in the line.
