Adding javaagent to process id or JVM start up

问题

I want to add a java agent to process ID of the already running java application. Is there any way doing that using command line, something like

java -jar java agent.jar process_id

or if i can edit the hotspot JVM start up script directly to add the java agent there itself, but how can i edit the hotspot JVM start up script. I am using UNIX.

If you are working with the sun JVM you can use the dynamic attach agent.
