java - 在外部上下文中未找到资源

标签 java spring maven primefaces externalcontext

我在 Eclipse Luna 上有一个 Maven 项目。

我的应用程序在 tomcat 7 上正常部署，但当我尝试访问它时，某些 primefaces 资源未加载，并且出现此异常:

GRAVE: Servlet.service() for servlet [Spring MVC Dispatcher Servlet] in context with path [/jee] threw exception [Request processing failed; nested exception is javax.faces.FacesException: /WEB-INF/javax.faces.resource/primefaces.xhtml Not Found in ExternalContext as a Resource] with root cause
com.sun.faces.context.FacesFileNotFoundException: /WEB-INF/javax.faces.resource/primefaces.xhtml Not Found in ExternalContext as a Resource

我还使用 Spring Web Flow 和在 tomcat 的 server.xml 文件上配置的外部上下文，如下所示:

*<Context docBase="D:\Desenvolvimento\workspace\j2eeapplication\target\j2eeapplication-0.0.1-SNAPSHOT" path="/jee" reloadable="true" />*

这是我的 web.xml

已检查 primefaces jar 是否位于 lib 文件夹中。不知道该怎么办。有人可以帮助我吗？

最佳答案

您是否尝试为每个标记创建一个 servlet-mapping 标记？

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/javax.faces.resource/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
