Question

I am looking for something simpler than JProfiler to profile a Java method, something that can hook into the JVM.

I call a method on an object (in JAVA)

ObjectX objectX= new ObjectX();

objectX.callSomeMethod();

I woudl like to be able to see all the methods and time that are called with this ocasion:

(Call tree)

callSomeMethod()    time took        

  - callOtherMethod()  time took         

          call other method  time took    
          call security method  time took    

  - callMethodx....        time took       

  .....

Is there a tool for gather this information ?

to be more clear i am looking for something more simple like SLF4J profiler

+ Profiler [BASIC] |
-- elapsed time [A] 220.487 milliseconds. 
-- elapsed time [B] 2499.866 milliseconds. 
-- elapsed time [OTHER] 3300.745 milliseconds.
-- Total [BASIC] 6022.568 milliseconds.

But on SL4j you have to manually put the code profiled in the code.

I was thinking is possible to have something similar via another profiling tool.

Thanks

What you are looking for is Java Profilers. I suggest you download a demo version of Yourkit and use it to profile your application.
