Howdy, -server is set like all other java runtime options, same place as -Xms and -Xmx. It must come before any other option though.
I would caution one to not blindly set -server. Try it and see what you get. For a couple of our apps, we got better performance (both throughput and garbage collection) without the -server switch, and these are apps for which -server makes sense on paper. (Above is for the 1.3.1 Sun JVM on Solaris 2.8).
