我在tomcat 6.0.20上托管的应用程序中使用JSF 2和richfaces 3.3.3。 一旦通过浏览器（Mozilla和IE）发出请求，应用程序就会崩溃。

我的web.xml如下所示：

<?xml version="1.0" encoding="UTF-8"?>

 javax.faces.webapp.FacesServlet.service(FacesServlet.java:309)

以递归方式记录堆栈跟踪，直到发生StackOverflowError。

如果删除与Richfaces相关的所有配置，该应用程序就像魅力一样。 任何建议都非常感谢。

首先，请更改此部分...... 

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

faces servlet应该映射到 .jsf，或者只映射到/ faces / 。然后禁用内置于JSF2 ...

的faces servlet 
<context-param>
    <param-name>javax.faces.DISABLE_FACELET_JSF_VIEWHANDLER</param-name>
    <param-value>true</param-value>
</context-param>

现在包括原始的facelets jar ......它应该像1.1.15版本之类的东西。这里发生的是JSF 1.x没有专门的视图技术，尽管大多数人使用JSP，但它有一些严重的缺点。因此，facelets作为专用视图技术集成到JSF2中。问题是RichFaces 3.x还没有完全支持JSF2，特别是它仍然依赖于独立的facelets项目。因此，您必须禁用内置facelets，并包含facelet的独立版本。另外，RichFaces4刚刚推出了Milestone 5，它非常接近候选版本（然后是稳定版本），它应该与JSF2完全集成

我正在使用JSF 2.0和Richfaces 3.3.3.Final，具有以下配置：

一切都按预期工作。

答案 2 :(得分：1)

你有没有理由使用JSF 2和RichFaces 3.3.3？对于JSF 2，您应该使用RichFaces 4.
