The jboss-as-5 plugin supports EAP 5.x and AS 6.x (AS 5.x is not supported dut to technical issues in the AS management interface). There is a new jboss-as7 plugin currently being developed that will support AS 7.x and EAP 6.x; if you'd like to try it out, the work is being done in a branch:

As for the tomcat plugin, I'm not sure whether it will work with Tomcat 7. I don't know of anyone that has tried it yet. You'll have to give it a try and see what happens.
