配置 RichFaces：java.lang.ClassNotFoundException：org.ajax4jsf.Filter

Question

我有一个包含一些 RichFaces 组件的项目。 除 RichFaces 外，所有其他组件都会显示。

从服务器日志中我得到：

java.lang.ClassNotFoundException: org.ajax4jsf.Filter

我知道使用 RichFaces 4.0，Web.xml 中不需要过滤器。

这是我的库：

1. ​​commons-beanutils-1.7.0.jar
2. commons-collections-3.2.jar
3. commons-digester-1.8.jar
4. commons-digester.jar
5. commons-discovery.jar
6. commons-logging-1.0 .4.jar
7. cssparser-0.9.5.jar
8. guava-r08.jar
9. jhighlight-1.0.jar
10. jsf-api.jar
11. jsf-facelets.jar
12. jsf-impl.jar
13. richfaces-components-api-4.0.0.Final.jar
14. richfaces-components-ui-4.0.0.Final.jar
15. richfaces-core-api-4.0.0.Final.jar
16. richfaces -core-impl-4.0.0.Final.jar
17. sac-1.3.jar

和这个 my web.xml

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.faces</url-pattern>
</servlet-mapping>

我正在使用 GlassFish 服务器3.1.1

我尝试了不同的配置，还尝试包含ajax4jsf.jar。但总是以同样的错误告终。非常感谢任何帮助。

完整的服务器日志如下所示：

Answer 1

从库中删除 jsf*.jar。 Glassfish3 已经提供了 JSF 2.x 库。另外，jsf-facelets.jar 是 JSF 1.x 的 Facelets 1.x。 JSF 2.x 库已包含 Facelets 2.x。

至于例外情况，只需从web.xml中删除org.ajax4jsf.Filter的即可。这是来自 RichFaces 3.x，在 RichFaces 4.x 中不再需要。确保您正在阅读 RichFaces 4.x 和不 RichFaces 3.x。
