java - Adding -javaagent to Tomcat 6 server, where do I put it and in what format?

Question

I′m trying to install an application health monitoring application that can monitor J2EE web transactions and I need to put a javaagent into my Tomcat somehow but am not clear on exactly how to do this, I am using Linux and have been instructed by the software company that makes this product to do something like below:

-javaagent:<Path to the WebTransactionAgent.jar>

I have received further support from them and they basically said to put this into the appropriate .sh file (but they weren′t able to tell me which file that is for Tomcat)

I tried putting this in the catalina.sh file but it does not seem to be working:

JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m -XX:MaxPermSize=256m -javaagent:"C:WebTransactionAgent.jar"

Any advice is appreciated

Answer 1

For Unix/Linux, do this in <tomcat_home>/bin/setenv.sh, e.g.

CATALINA_OPTS="$CATALINA_OPTS -javaagent:/path/to/YourJar.jar"

You might need to create this file if not present and chmod it to 711 or 755.

For Windows, the counterpart is setenv.bat.
