Profiling a JNI invocation API-based application using TPTP 4.2 [message #139582] Sat, 17 January 2009 19:44

Good morning;

I need to profile a java application launched by the JNI invocation API
from a C application, and naturally the TPTP tools seemed like a good
place to start. However, I can start the application, but I have no
idea how to connect to it for profiling. I realize this falls into the
'dumb newbie' bucket, but I really am kind of lost. Permit me to explain:

I have added the JVM option "-XrunpiAgent:server=controlled" to my java
VM startup options.

I have added
$ECLIPSE_HOME/plugins/ 2_4.4.1.v200808290100/agent_controller/lib

I am running against the Sun Java 1.5.0_10 JVM library

In Eclipse, I have a Java project that contains the code I wish to
profile. I've got no profiling launch configurations, nor do I really
know what needs to go into them.

It is at this point that my knowledge comes to an end; when I start my
JNI-based application, it simply stops during VM startup and sits
awaiting, presumably, an agent controller connection. What steps do I
need to take to get this to happen, and to get information from it?
