JSF在目标页面上不起作用

发布于 2024-11-30 11:15:48 字数 6416 浏览 0 评论 0原文

我正在制作一个简单的 JSF 应用程序，它使用模板，这是非常基本的东西，但需要花费很多时间来找到修复程序。问题是，我有index.jsp，它只是将请求转发到startPage.xhtml。 startPage.xhtml 使用 main.xhtml 进行模板化。到这里一切都好。但 startPage.xhtml 中有一个锚链接，它将控件引导至 expression/expression.html。当我单击该链接时，浏览器不会呈现我的页眉和页脚（main.xhtml 模板的一部分）。 IE 将表达式/表达式.xhtml 视为文件并使用打开/保存对话框将其打开。

Index.jsp

<html>
 <body>
  <jsp:forward page="startPage.jsf" />
 </body>
</html>

main.xhtml

有什么建议吗？

注意：由于页面上的所有链接都是静态的，所以我没有使用任何托管 bean。

I am making a simple JSF application which is uses templating It's very basic stuff but taking a lot of time to find the fix.
Issue is, I am having index.jsp which just forwards the request to startPage.xhtml. startPage.xhtml uses main.xhtml for templating. Till here everything is ok. But there is a anchor link of startPage.xhtml which leads the control to expression/expression.html. When I click on that link browser is not rendering my header and footer (part of main.xhtml template). IE consider expression/expression.xhtml a file and open it with open/save dialogue.

Index.jsp

Any suggestions?

您的 index.jsp 表明 FacesServlet 位于 web.xml 中，映射到 *.jsf。

然而，

表达子系统

您的 startPage.xhtml 具有指向 expression.xhtml 而不是 expression.jsf 的链接。 IE 正在检索原始且未解析的 JSF 源代码，而不是其生成的 HTML。每当 IE 检索 application/xhtml+xml 文件时，它不知道如何处理它，因此它会要求下载它。

您需要修复链接以匹配 web.xml 中 FacesServlet 的。

<a href="#{request.contextPath}/expression/expression.jsf" style="font-size:20px;"> Expression Subsystem</a>

（请注意，我还简化了上下文路径检索）

或者，您也可以将 FacesServlet 的更改为*.xhtml。这样您就可以完全摆脱丑陋的 index.jsp 并将设置为 startPage.xhtml 并使用 URL /links 始终以 .xhtml 结尾。

<jsp:forward page="startPage.jsf" />

Your index.jsp suggests that the FacesServlet is in web.xml mapped on an <url-pattern> of *.jsf.

However,

<a href="${facesContext.externalContext.requestContextPath}/expression/expression.xhtml" style="font-size:20px;"> Expression Subsystem</a>

your startPage.xhtml has a link to expression.xhtml instead of expression.jsf. IE is retrieving the raw and unparsed JSF source code instead of its generated HTML. Whenever IE retrieves an application/xhtml+xml file, it doesn't know what to do with it, so it asks to download it.

You need to fix the link to match the <url-pattern> of the FacesServlet in web.xml.

<a href="#{request.contextPath}/expression/expression.jsf" style="font-size:20px;"> Expression Subsystem</a>

(note that I also simplified the context path retrieval)

Alternatively, you can also just change the <url-pattern> of the FacesServlet to *.xhtml. This way you can get rid of the ugly index.jsp altogether and set your <welcome-file> to startPage.xhtml and use URLs/links ending in .xhtml all the time.
