You're trying to profile your application in 'launch' mode. Try attaching
to it instead by running your Tomcat server with the following VM
argument: -XrunpiAgent:server=enabled. Make sure that the Agent
Controller has started before running your Tomcat server. After starting
the server, create a new 'attach -java process' launch configuration by
clicking on the profile button -> 'profile..', select 'localhost' in the
host list, switch to the agent tab and select your agent, select the
profiling tab and make sure you set the appropriate filters in your
profiling set, click on profile to start profiling. Let me know if you
need more help.

** Due to the numerous questions posted on the newsgroup about using TPTP
to profile J2EE applications, I'm going to open a new enhancement for
creating a doc that explains how this can be done. **

Just a few comments on Profiling Tomcat applications such as servlets:

- You need to edit the catalina.bat (on Windows). Find the lines with
%_EXECJAVA%. Add the -XrunpiAgent:server=enabled option on the lines as
Navid suggested. Here is an example from my catalina.bat:
%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %DEBUG_OPTS%
-Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%"
-Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%"
-Djava.io.tmpdir="%CATALINA_TMPDIR%" -XrunpiAgent %MAINCLASS%
%CMD_LINE_ARGS% %ACTION%
If you execute catalina.bat, Tomcat will be started with profiling enabled.

- Make sure the <RAC_install>\bin is on your path, otherwise the
piAgegent.dll will not be found. See the "Getting Started" html
document on the RAC install directory.

- Now you can attach to Tomcat using TPTP workbench as usual.

- Make sure you create the appropriate filtering. Otherwise you will
get too many profiling information on classes you may not be interested.
I am usually interested in my servlet classes and filter out the rest.

I was just wondering with which JDK's version this option
(-XrunpiAgent:server=enabled) is compatible. AMOF doing 'java -X' on a JDK
1.4.2 & 1.5.0_02, I get nothing refering to that option.

\T,

Typpically, I get smthg like this
C:\>java -version
java version "1.5.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_02-b09)
Java HotSpot(TM) Client VM (build 1.5.0_02-b09, mixed mode)

C:\>java -X
-Xmixed mixed mode execution (default)
-Xint interpreted mode execution only
-Xbootclasspath:<directories and zip/jar files separated by ;>
set search path for bootstrap classes and resources
-Xbootclasspath/a:<directories and zip/jar files separated by ;>
append to end of bootstrap class path
-Xbootclasspath/p:<directories and zip/jar files separated by ;>
prepend in front of bootstrap class path
-Xnoclassgc disable class garbage collection
-Xincgc enable incremental garbage collection
-Xloggc:<file> log GC status to a file with time stamps
-Xbatch disable background compilation
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
-Xss<size> set java thread stack size
-Xprof output cpu profiling data
-Xfuture enable strictest checks, anticipating future default
-Xrs reduce use of OS signals by Java/VM (see
documentation)
-Xcheck:jni perform additional checks for JNI functions
-Xshare:off do not attempt to use shared class data
-Xshare:auto use shared class data if possible (default)
-Xshare:on require using shared class data, otherwise fail.
