Issues with Tomcat 5.5 and Myfaces 1.1.4

[Ly Le]

Hi,   I deployed myfaces application with Tomcat 5.5.  It was working fine until yesterday, I always get this error:   SEVERE: Error configuring application listener of class org.apache.myfaces.webapp.StartupServletContextListener java.lang.ClassNotFoundException: org.apache.myfaces.webapp.StartupServletContextListener             at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1355)   I followed the instructions on http://myfaces.apache.org/tomcat.html, removing the commons-el.jar file (there’s no jsp.jar in myfaces v1.1.4), clean my webapp and tomcat cache, redeploy, restart and still get the issue.  Any idea what else could I do?   Thanks ly
