Using Update Manager with Europa Discovery site, I installed just TPTP
Java Profiling component and the required TPTP Platform component
(sorry, I can't remember the exact name of these two components; I can
only state for sure that I didn't install the following:
TPTP Reporting with BIRT
TPTP Profiling for Web applications
TPTP Testing Tools Project
TPTP Tracing and Profiling Tools Project
because I thought I didn't need them)
When the installation finished, I accepted to restart Eclipse.
Then, I created a new profile for an application that hadn't any run
profile: I selected to profile as Java Application, I set up project and
main class, under Monitor tab I selected Execution Time Anaylisis (JRE
1.5 or newer) and then clicked on Profile
Eclipse tries to start the application, but many times I got:
- no output in the console (it stays grey)
- no output in Profiling and Logging perspective
After some seconds, Eclipse seems to have stopped to try to launch the
application. In the log under .metadata I see:
!ENTRY org.eclipse.hyades.trace.ui 4 4 2007-08-02 10:41:10.281
!MESSAGE java.lang.NullPointerException

at
org.eclipse.tptp.trace.ui.provisional.launcher.PrimaryLaunch Delegate.run(PrimaryLaunchDelegate.java:246)
at java.lang.Thread.run(Unknown Source)
Then, for some reason, after I tried to open the progress view, then I
started to experience the following:
- now, the console is allocated, but stays white (empty)
- in the progress view I can see "Launching <profile name>"/"Launching :
Launching delegate..." then "Launching <profile name>"/"Launching the
Java application"
- an alert is given with the following error (also present the in log):

What's wrong?

By the way, I'm using:
- Windows 2000
- Eclipse 3.3 (build ID: I20070625-1500)
- JDK 1.5.0_12
I didn't install any agent controller, because in the guides I read that
it is not needed when profiling a local application.

Hi Valentina,
thank you for your support.
Now I installed all TPTP components, but the time-out problem persists.
I noticed that other people are experiencing the same problem: see
threads "TIme-out occurred while attempting to launch the process" by
Daniel Cheng (14/12/1006) and "A time-out occurred while attempting to
launch the process" by Ron Kinney (10/04/2007) in this newsgroup.
Unfortunately, it is not clear if they solved the problem.
I do have EMF and XSD, because (I forgot to mention) I already have also
WTP installed.
I also tried to use the standalone agent controller, to see if the
problem were the IAC, but a part from the fact that there are some
aspects that are not clear (please see my thread "Some (stupid?)
questions about TPTP and Agent Controller" posted today), even when I
think I got to use the standalone agent controller the result was the same.
I tried to change filters, thinking that the problem might have been too
much data to profile: I even tried to exclude all packages and to
include just those of my application, but it didn't help.
I also tried to profile a simple HelloWorld application, but I still
encouter the error...
I don't know what to do :-( I can remember that one year ago (more or
less) I got TPTP 4.1.0 working on an old Eclipse 3.2 (or was 3.1?)
installation...
I noticed that Windows 2000 is not mentioned as a supported platform...
may be this the problem?
Mauro.
