There are a lot of java profilers out there, any recommendations as to what would be best for profiling a java web start application that is being deployed to glassfish inside a war?

Well, the traditional answers for such a question are VisualVM and/or Yourkit (if you have money).
If you go for VisualVM, this thread will help you to configure your Webstart application for JMX.
If you go for Yourkit, have a look at this discussion.
