I searched this list and found another posting about this by
Jim O'Neill - but his solution is not working for me.
I have installed and configured absolutely fresh copies of:
Also I started with an empty workspace to make sure no
outdated versions of whatever hang around. I never had any
other TPTP version or so installed.
I configured the tomcat in
Window-Preferences-Server-Runtimes and created a web app to
launch with it. The server starts in normal and debugging
mode without problems.
But when I try to start the server in profiling mode, I get
to choose the profiling options (Execution time analysis
etc.) and after that tomcat fails to start with the error
Can anyone please help me with this problem?
Many thanks in advance

could you please at least give me the last version successfully used and
tested under Red Hat Enterprise Linux 4.4 ?
I'm very disappointed. I hoped using TPTP in my project (since I'm
eclipse rcp developper), however, this serious and unsolved issue is
blocking me. I have no idea about the problem evoqued below.
Any news, suggestion is welcome !
