Java Compilation Problems (2)

Ah well, in this blog I would like to address an issue that had confronted me about 2 years ago. I really had to pull out all my hairs to resolve this problem at that time since I received no external help. But as good as your luck turns out to be, I am just glad to be able to help. Setting classpath variables is a headache for novice programmers. So i'll try to make it as simple as possible.

To execute a java program from any directory in your system, u need to do the following (this is for windows XP users only) :

1) Right click on My Computer->properties
2) Go to the Advanced tab
3) You shall see a small button named Environment variables. That's the one u need to click.
4) A dialog box will open up showing the various system variables.
5) U need to add a new environment variable in the user variable dialog box. Click on new.

Add the following:
Variable name : PATH
Variable value : the complete path to the bin folder of your java installation directory
For example, on my system, the setting is the follows:
Variable name : PATH
Variable value : C:\Program Files\Java\jdk1.5.0_12\bin

There you go. Just go and have a good time playing around with all the java files that u can, and experience the ease with which you can compile the files without setting the classpath each time or painfully copying the files to the bin folder.
