I want to share my experience with this Exception. My JSF 2.2 application worked fine with WildFly 8.0, but one time, when I started server, i got this "Target Unreacheable" exception. Actually, there was no problem with JSF annotations or tags.

Only thing I had to do was cleaning the project. After this operation, my app is working fine again.

I hope this will help someone!
