This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Is it the CLASSPATH you're trying to set, or the PATH? What are you doing, and what errors are you getting?
Setting the PATH variable allows you "to conveniently run the JDK executables (javac.exe, java.exe, javadoc.exe, etc.) from any directory without having to type the full path of the command." To set the PATH, see these installation instructions for 32-bit Windows. (For other operating systems, click here.)
Setting the CLASSPATH variable "tells JDK tools and applications where to find third-party and user-defined classes." To set the CLASSPATH, see these JavaRanch instructions or Sun instructions. [ January 04, 2006: Message edited by: marc weber ]

If you are posting in this forum, then you should NOT use the CLASSPATH variable AT ALL. You should delete it completely.
If that still does not fix the problems you have encountered, please describe what you are doing and what error messages you get. These details will help us fix your exact problem rather than wasting your time with out best guesses.
