[news.eclipse.tools.hyades] Re: Profiling Applet running in Browser Java

[curtispd@xxxxxxxxxx (Curtis d\'Entremont)]

Hi Vasu,

In order to profile an applet running within a browser, you need to find a 
way to configure the browser to invoke the applet's JVM with an additional 
JVM argument: "-XrunpiAgent", or "-XrunpiAgent:server=controlled". The 
former will start running the applet immediately, and the latter will 
cause the JVM (and the applet along with it) to pause execution until a 
profiler attaches to it. This is probably very browser-dependant, and not 
all browsers may support doing this. To attach the profiler to the applet, 
click the "Profile" button in the main toolbar and create a new "Attach - 
Java Process" launch configuration. Find your agent, set your profiling 
options, and you're ready to go. If you picked the "server=controlled" 
option, the applet will start running when you do a "Start monitoring" on 
the agent in the profiling monitor view. This is useful if you don't want 
to miss anything that happens at startup.

I should mention, though, that this is the *hard* way to profile applets. 
There's a much easier way - do it outside the browser. Simply click on the 
"Profile..." button in the main toolbar and create a new "Java Applet" 
launch configuration. This will run the applet in a small applet viewer 
application.

Thanks,
Curt
