Profiler for java-based web application?

You can start with jvisualvm in the Sun 6 JDK which allows you to attach to a running JVM and gather basic memory and cpu profiling data. This allows you to get a rough idea of what is going on, and if better profiilng tools are necessary.

I have used JProfiler, JProbe, and DynaTrace. DynaTrace is the most expensive choice but I found it as the most useful one so far. They also have a DynaTrace Ajax Client that's free and lets you profile on the front end side (java script execution, ajax calls, rendering time, etc).

You can also use Fiddler to capture execution times.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
