Tomcat shows the following error:   SEVERE: Error listenerStart Mar 10, 2006 12:21:30 AM org.apache.catalina.core.StandardContext start SEVERE: Context startup failed due to previous errors   This causes the application to not start.   Is Facelets compatible with My Faces?   I’ve copied the following files to my WEB-INF/lib:   /jsf-facelets.jar (version 1.0.12) /el-api.jar /el-ri.jar   But not the jars related to Sun RI.   Added this to my web.xml:   <context-param>   <description></description>   <param-name>facelets.DEVELOPMENT</param-name>   <param-value>true</param-value>  </context-param>  <context-param>   <description></description>   <param-name>javax.faces.DEFAULT_SUFFIX</param-name>   <param-value>.xhtml</param-value>  </context-param>   ,and the following to faces-config.xml:     <application>   <view-handler>com.sun.facelets.FaceletViewHandler</view-handler>  </application>   Could you guys help me with this?   Thanks.
