Java 1.5 - Application Memory Monitoring Made Easy

There is a new tool called Java Monitoring & Management Console in 1.5 edition of J2SE (available as %JDK_HOME%\bin\jconsole.exe). Simply set
JAVA_OPTS=-Dcom.sun.management.jmxremote

and start your Application Server or Servlet Container. Launch JConsole tool, and when asked for attaching, pick the appropriate process to attach.

[Pic 1 - Choose a Process to attach to.]

[Pic 2 - JConsole in Action]

I have a JDK 1.6 on W2K machine.

Here is a link from Sun's Java website.

This is interesting but not really much more than what existing OS tools can do. What I'm still waiting for is an easy way to check per object memory usage without latching JProfiler into the mix. That would be a dream.

@Rockstar.
Try the netbeans profiler or if you have resources to buy, yourkit profiler is a very good java profiler. you can try the software for 15 days.
Netbeans profiler is pretty good and should do most of your tasks

JSP Performance Tips

Here are a few tips to improve JSP performance that I have been using. If you have your own listing of the tips, plz share. Disable JSP auto reloading feature. Use thread pool for your JSP engine and define the size of thread pool as per application requirement. Use jspInit() method to cache static data Initialize the 'out' object (implicit object) with proper size in the page directive. Set the content length Give 'false' value to the session in the page directive to avoid session object creation. Flush the data partly Use StringBuffer rather than using + operator when you concatenate multiple strings Use include directive instead of include action when you want to include the child page content in the translation phase. Avoid giving unnecessary scope in the 'useBean' action. Use print() method rather than println() method Use ServletOutputStream instead of JSPWriter to send binary data Minimize code in the synchronized block Do not use custom tags if you do no...

How old are the daughters?

Two MIT math graduates bump into each other at Fairway on the upper west side. They hadn't seen each other in over 20 years. The first grad says to the second: "how have you been?" Second: "Great! I got married and I have three daughters now" First: "Really? how old are they?" Second: "Well, the product of their ages is 72, and the sum of their ages is the same as the number on that building over there.." First: "Right, ok.. oh wait.. hmmmm.., I still don't know" second: "Oh sorry, the oldest one just started to play the piano" First: "Wonderful! my oldest is the same age!" Problem: How old are the daughters?
