<display-name>first</display-name>

is a description part and I don't think you can call your web service via this name. Instead, try calling it like

http://localhost:8080/{nameOfYourWARFileHere}/rest

Also make sure to put rest into your @Path("/") annotation in RestServ.java right after the slash otherwise the request mapping won't work.
