JSF2和Facelets - java.io.FileNotFoundException

我的JSF 2項目結構如下：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

我遇到這個錯誤，當我試圖在http://localhost/home/main/index.jsf查看我的網頁：

的index.xhtml的內容是：

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

<ui:composition template="templates/commonLayout.xhtml"> 
    <ui:define name="header"> 
     Add your header here or delete to use the default 
    </ui:define> 
    <ui:define name="content">

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

我一直在這個問題上停留了兩天。任何人都可以看到問題是什麼？我完全不知道

兩件事：

首先，您的項目結構不正確。所有的Web文件都必須進入WebContent內部。

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，這會產生一個404錯誤，而不是這個例外。所以我認爲這只是你在制定問題時的粗心大意。其次，如果ui:composition中的template路徑以/開頭，那麼它是相對於WebContent的。但是，如果它不是以/開頭，那麼它是相對於當前文件。正如您目前所擁有的，Facelets將嘗試從/views/main/templates/commonLayout.xhtml加載模板，這確實是不正確的。因此，修復您的template路徑如下：

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

@BalusC感謝您的提示。我對整個JSF 2項目設置感到困惑。這個鏈接[link] http://www.coreservlets.com/JSF-Tutorial/jsf2/#Overview表示所有的Web文件都必須進入WebContent內部 - 與您所說的相同。另一個鏈接[link] http://www.mkyong.com/jsf2/jsf-2-templating-with-facelets-example/在其示例下載中具有WebContent之外的Web文件。你能指點我一個權威的網站，這將更清楚地解釋這一點。 – ChuongPham 2011-02-15 16:34:51
