Hi Alex,
With WTP-TPTP integration, you can start the Tomcat instance in workbench in
profiling mode. It will enabled Tomcat with the necessary profiling option
automatically. However, the Tomcat server is started in enabled mode.
Were you running the profiling session in memory analysis(HeapProf) or
execution analysis(CGProf), or thread analysis(ThreadProf)?
