Simple Java Rectangle

[niharkd]

Hi,
I am trying to run the program below. IT compiles fine and also runs. However, once the jframe loads and the container loads, I dont see any rectangle being drawn in there. Can anyone please help?
I am using jGrasp development environment with JDK 5.
I am running this on a Windows XP w/ SP2 OS
Thanks
Nihar
