I can run JProfiler 5 against Tomcat 5 stand-alone, but now I’m trying to get it to talk to Tomcat when it’s running under MyEclipse. I added this optional VM argument:

-agentlib:jprofilerti=port=8849

and I added the path to agent.jar to be appended to the classpath.

When I try to start Tomcat, it fails with this error in the log:

org.eclipse.core.runtime.CoreException: JProfiler> Protocol version 24
JProfiler> Using JVMTI
JProfiler> 32-bit library
JProfiler> Listening on port: 8849.
JProfiler> Native library initialized

It looks like JProfiler’s startup message is being interpreted as an error?

When I similarly configure YourKit, it works fine and outputs some lines to the console. (They show up in red — stderr?)

Has anyone had luck with getting JProfiler to talk to Tomcat 5 under MyEclipse?

Oh, I should have mentioned this is MyEclipse 5.5.1, using the all-in-one installer on Windows XP Pro. Sun JDK 1.5.0.

Hi JeremyStein,
Unfortunately I have no experience with JProfile or I cant figure out why its giving you this error when you are trying to get it to work with MyEclipe. I hope some user who is more well versed with this can help with out. Sorry about that.

Step 1: In Linux machine open .bash_profile file from /root directory
Enter jprofiller location (using below command export) in .bash_profile file
export LD_LIBRARY_PATH=/dsvol/jprofiler6/bin/linux-x86

Step 2: Go Tomcat installation directory. Open catalena.sh file from bin folder
Enter the below details in catelana.sh file (only red color information and black color you can find by default in catalena.sh file)
export JPROFILER_HOME
JAVA_OPTS=”-Xms768m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=256m -Dfile.encoding=UTF8 -agentpath:/opt/Performance/jprofiler7/bin/linux-x86/libjprofilerti.so=port=8849 $CATALINA_OPTS”

Step 3: Start the server from bin folder by executing the starup.sh command
