Hi Pavol,
I have removed the specified jars, and also migrated to Rich Faces 4.3.5, even still i am getting the same error.
I could not able to solve this.
is there any alternative solution for this?
and we cannot migrate to WildFly because we are in the middle of migration process.
I think the simple way is creat a clean richfaces project with jboss tool, start it to be sur there is no problem with your jboss server, then compare this project with your project, the libs, faces-config and web.xml to find the problem.
