Configuring for RichFaces: java.lang.ClassNotFoundException: org.ajax4jsf.Filter

问题

I have a project that contains some RichFaces components. All other components get displayed but the RichFaces.

From the server logs I get:

java.lang.ClassNotFoundException: org.ajax4jsf.Filter

I am aware that with RichFaces 4.0 no filters are needed in the Web.xml.

Here is my library:

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

and this 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>

I am using GlassFish server 3.1.1

I have tried different configurations, also tried to include ajax4jsf.jar. But always ended up with the same error. Any help is greatly appreciated.

the complete server log is shown here:

回答1:

Remove jsf*.jar from your libraries. The JSF 2.x libs are already provided by Glassfish3. Also, jsf-facelets.jar is of Facelets 1.x for JSF 1.x. The JSF 2.x libs already include Facelets 2.x.

As to the exception, just remove <filter> of org.ajax4jsf.Filter from web.xml. This is from RichFaces 3.x and not necessary anymore in RichFaces 4.x. Make sure that you're reading developer documentation for RichFaces 4.x and not RichFaces 3.x.
