The XRebel Java Profiler ist a lightweight Java Profiler frmo zeroturnaround, the makers of JRebel and also the Optimizer for Eclipse Plugin (Speeding up Eclipse). To include the profiler in your web application, a single VM argument needs to be passed and a little icon will be displayed at the bottom left of every page.
