Here is the things I tried
EDIT :-
Even after doing above points i am not able to see the Jboss server in eclipse mars so i tried below
Go to eclipse market place - > search for Jboss -> Then from List Red Hat Jboss Developer Studio(Mars) 9.0->Confirm
Even now i am not able to see Jboss server in the eclipse add server list so not able to run my application in Jboss server .
Can any one tell me what can be the issue why Jboss server not listed in the server List?
EDIT 1 :-
You need Java 8 to run Eclipse with JBoss Tools 4.3.0.Beta1 even if you don't build and deploy with this version of Java (ie, you can still build and deploy on Java 6 or 7). See http://tools.jboss.org/blog/2015-06-23-beta1-for-mars.html#java-8-to-run-eclipse-older-runtimes-ok-for-builds-deployment
