Are you sure you did that correctly? Please go through this FAQ.

Welcome to the Ranch

Did you reopen your command line after setting the PATH? You might need to reboot your computer if using DOS.
If that doesn’t help, please show us exactly what you have done, including your PATH.

Welcome to the Ranch! I guess that with "DOS" you mean the Windows command prompt. Java doesn't run on MS-DOS.

Do you mean we have JRE for Windows and not for DOS?

Yes indeed, but nobody seriously uses MS-DOS anymore.

sorry! i meant command prompt. i have tried to set the class path again but its bringing another error.

javac: file not found: myjavafilename
Usage:javac<Options><source files>

Go back and delete the classpath you set. Lots of people advise you to set a system classpath, but it usually causes more harm than good.

. . . but that sort of error message suggests you have got your PATH correct now.

Are you in the directory that contains the source file? If not, then go there with the cd (current directory) command. Are you sure you are typing the name of your Java source file correctly?

Thanks everybody! I eventually got it through FAQ
