JSF Deployment Error in Eclipse IDE

Hi

In JSF I got the error while deploying a JSF Application on tomcat server using eclipse's Run As -- > on a server

SEVERE: Exception sending context initialized event to listener instance of class com.sun.faces.config.ConfigureListener

Solution :

The solution for above kind of errors are tricky to find since we will be in a state that we provide jsf jars required to run but still the error props up.

The reason is, in eclise when we run as on a server, server while running the application makes use of the jars which we provide. There might be a case we are missing the libraries provided to the server run-time

please check that and it will be running normal
