Setting environment variables

I set the path variable to the bin directory ie D:\Program Files\Java\jdk1.6.0\bin and JAVA_HOME to the parent folder ie D:\Program Files\Java\jdk1.6.0\
I can successfully compile my program using javac but when i run it using java it always gives me some class error!!
I've tested it with some basic programs such as only a single println statement but it does'nt run.
But, it works fine from within the java's bin folder when the .class file is present there!

I think you have to set your classpath

Go to the path
D:\Program Files\Java\jdk1.6.0\bin\

and type

set classpath D:\Program Files\Java\jdk1.6.0\lib (or whereever you want to put your classes)

Do NOT set your CLASSPATH, and do NOT set it to JDK/lib. Ever. Nobody ever do this. Seriously. Ugh.

There are a few different things that might be going on -- if you tell us the exact text of the error message we can tell you the proper way to deal with it.

I think you have multiple Java versions installed in your machine just delete the old version and try with new version JDK 1.5 .
