I'm not familiar with Apache Turbine, but is there a reason not to
include the jar(s) in WEB-INF/lib? As far as I know, "setting up a
framework" is just a matter of including in the Dynamic Web project what
is needed per the requirements of the framework.
With respect to TPTP, there are a couple of bugs affecting profiling use
with WTP servers, Bug 174863[1] for WTP 1.5.3 and Bug 174886 for WTP 2.0
M5. You haven't mentioned with versions of Eclipse and WTP you are
using, so I can't say if they apply. If you have th TPTP SDK for
profiling, it's fairly easy to patch TPTP to get it working with WTP
1.5.3 and WTP 2.0M5.
I assume the VM argument you are referring to is "-XrunpiAgent", which
is what TPTP silently adds. To help the piAgent to be found, I add a
"PATH" environment variable to the launch configuration that includes
the path to the directory containing the piAgent.dll in TPTP, i.e. the
directory for the org.eclipse.hyades.execution.win32.x86_??? plug-in.
If the piAgent isn't found when executing Profile on server, then Tomcat
won't start.
Cheers,
Larry
