JSF2和Facelets - java.io.FileNotFoundException

我的JSF 2项目结构如下：JSF2和Facelets - java.io.FileNotFoundException

root 
... 
    WebContent 
     META-INF 
     resources 
     css 
     images 
     javascript 
    templates 
     commonLayout.xhtml 
     footer.xhtml 
     header.xhtml 
    views 
     main 
     index.xhtml 
    WEB-INF 
    index.jsp

我遇到这个错误，当我试图在http://localhost/home/main/index.jsf查看我的网页：

的index.xhtml的内容是：

<html xmlns="http://www.w3.org/1999/xhtml"

<ui:composition template="templates/commonLayout.xhtml"> 
    <ui:define name="header">

    <ui:define name="content">

    <ui:define name="footer"> 
     Add your footer here or delete to use the default 
    </ui:define> 
</ui:composition> 
</html>

我一直在这个问题上停留了两天。任何人都可以看到问题是什么？我完全不知道

两件事：

首先，您的项目结构不正确。所有的Web文件都必须进入WebContent内部。

root 
... 
    WebContent 
     META-INF 
     resources 
     css 
     images 
     javascript 
     templates 
     commonLayout.xhtml 
     footer.xhtml 
     header.xhtml 
     views 
     main 
      index.xhtml 
     WEB-INF 
     index.jsp

然而，这会产生一个404错误，而不是这个例外。所以我认为这只是你在制定问题时的粗心大意。其次，如果ui:composition中的template路径以/开头，那么它是相对于WebContent的。但是，如果它不是以/开头，那么它是相对于当前文件。正如您目前所拥有的，Facelets将尝试从/views/main/templates/commonLayout.xhtml加载模板，这确实是不正确的。因此，修复您的template路径如下：

<ui:composition template="/templates/commonLayout.xhtml">

@BalusC感谢您的提示。我对整个JSF 2项目设置感到困惑。这个链接[link] http://www.coreservlets.com/JSF-Tutorial/jsf2/#Overview表示所有的Web文件都必须进入WebContent内部 - 与您所说的相同。另一个链接[link] http://www.mkyong.com/jsf2/jsf-2-templating-with-facelets-example/在其示例下载中具有WebContent之外的Web文件。你能指点我一个权威的网站，这将更清楚地解释这一点。 – ChuongPham 2011-02-15 16:34:51
