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 : commons-beanutils-1.7.0.jar commons-collections-3.2.jar commons-digester-1.8.jar commons-digester.jar commons-discovery.jar commons-logging-1.0.4.jar cssparser-0.9.5.jar guava-r08.jar jhighlight-1.0.jar jsf
