Hello All,

I am using JBoss 5.1.0. I have deployed ear which contains war module. When i try to invoke any servlet from war getting the below exception.

I have seen the posts regarding the similar issue but could not come to any conclusion. Could anyone please tell me how to resolve this?

I am not having any class files or jar files with package "javax.servler.*" in WEB-INF/lib
