【问题描述】：

我开始使用以下技术创建项目

JSF 2.0 
Springwebflow 2.0
Primefaces 2.2.1
Richfaces 3.3
Appserver : JBOSS-AS-7.1.1 Final

我的应用程序已成功部署，但是当我尝试运行它时.. 我收到以下异常，

异常

org.springframework.web.util.NestedServletException: 请求 处理失败；嵌套异常是 org.springframework.webflow.execution.FlowExecutionException： 在流“主”的状态“startPage”中引发异常 org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:583) org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:501) javax.servlet.http.HttpServlet.service(HttpServlet.java:734) javax.servlet.http.HttpServlet.service(HttpServlet.java:847) org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:178) org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:290) org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:388) org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:515) org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:96) org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76)

【问题讨论】：

  • 你是如何用jboss 7.1.1配置jsf2.0的？
  • 您能否也发布您的 applicationContext，如果您正在开始一个新项目，我建议您查看 Springfuse 生成的代码以使事情变得更容易。这是link
  • 是的 Mukul，我配置了。
  • 我不做 SWF，但我知道它带有一个自定义的 FacesContext 实现，FlowFacesContext。此异常表明它没有正确引用/维护ExternalContext。尝试升级到最新的 SWF 版本。
  • 我将我的 SWF 升级到 2.3，但仍然遇到同样的异常。

【解决方案1】：

将你的 jsf 升级到 2.2.15，我在项目中遇到了同样的问题！
