大家好，

我在 weblogic 10.3 上安装了 jboss-seam（有很多问题 :( ）但现在它可以工作了，我的应用程序已部署。

但是现在，我遇到了一个新问题，我的 JSF 没有被解释并且 JSF 代码出现在 HTML 中。

这是我的 web.xml：

我的 FacesServlet 在启动时加载，但 JSF 不起作用。

有人可以帮助我吗？

谢谢。

【问题讨论】：

我不明白你如何使用Seam，同时在web.xml 文件中声明EJB 引用。一旦您启用 Seam EJB 拦截器，Seam 就会负责注入任何 EJB。
此声明是强制性的，以与 weblogic 兼容。它在文档中，所以我认为很好；）
您确定@debug@ 在 web.xml 中有效吗？
我不知道，我从文档中复制了这个^^。我是 J2EE 新手，所以我不了解所有配置。

【解决方案1】：

如果XHTML页面没有被FacesServlet解析，那么仅仅意味着请求的URL与FacesServlet的url-pattern不匹配。您已将其 url-pattern 设置为 *.seam 因此，要打开 JSF 页面，您不应通过 http://example.com/page.xhtml 调用它，而应通过 http://example.com/page.seam 调用它。

顺便说一下，javax.faces.DEFAULT_SUFFIX 设置了 JSF 应该查找和解析的模板文件的实际文件扩展名。您也将其设置为 .seam，但这应该是 .xhtml。

【讨论】：

javax.faces.DEFAULT_SUFFIX 应设置为模板文件的实际文件扩展名。这是通常 .xhtml。但是，如果您真的在使用扩展名为 .seam 的模板文件，那就顺其自然吧。然后我只质疑为什么您可以“普通”地查看 XHTML 文件。您应该已经找不到 404 页面。您确实需要提供更多信息：1) 实际文件扩展名是什么？ 2) 你在请求 URL 中（在浏览器的地址栏中）使用了什么扩展？

【解决方案2】：

我不知道这是否有帮助，但这是我们的 web.xml

【讨论】：

有一点很奇怪。在监控 servlet 中，我看到 FacesServlet 的“调用总数”在每次页面加载时都会增加。但是 jsf 没有被解释。很奇怪……

【解决方案3】：

我的 web.xml 中有这个：

<filter>
        <display-name>RichFaces Filter</display-name>
        <filter-name>richfaces</filter-name>
        <filter-class>org.ajax4jsf.Filter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>richfaces</filter-name>
        <servlet-name>Faces Servlet</servlet-name>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
    </filter-mapping>

现在，它正在工作。
