I have started using TPTP to test out profiling and analyzing a larget
tomcat application I develop. I have previously used optimizeit to
analyze my code for inefficient code paths.

I am using eclipse 3.1m5a with TPTP with 4.0-200503071459. My tomcat
5.5 is on a remote machine and I have a RAServer on the same machine as
the tomcat container.

In optimizeit (and in the community eclipse profile plugin) one can
analyze a method by the amount of time it takes in the entire running
history of the application. I can expand the method and see the child
invocations of other methods and how they breakdown. I can do this
recursivly looking for where the most time is being taken by the method.
Is there an equivalent view with TPTP? Execution flow seems to show a
history of method invocation over time with each invocation getting its
own representation. I want a aggregation of all the invocations and the
analyze the the aggregation of child calls. How can I do this?

When I use the graphical execution flow view, I get a thread with a
solid black block because of the number of method invocations. I use
the zoom tool to expand the block and I start seeing individual calls,
but by then the graphical representation is so large it is bigger than
the eclipse window and I just see lines. When I try and scroll it takes
forever because the window seems to redraw the entire graph (which is
quite big) each scroll increment. As a result the graphical view is
unusable for me. Is there a log or table view of the execution history?

Whenever I try and open the source for a method I get |WAS0020| error
about source not found. The java and debug views find the source just
fine, why can the profile view? I imported the java projects into the
profile project, but it doesn't seem to make a difference.

Thanks for the help,
