Unfortunately I'm not able to post links yet, however a simple google search for "setting classpath for java" will yield several pages which can give you instructions on how to do that. The problem is it's different for each operating system, and probably slightly different between different versions of the same OS (i.e. it might be a slightly different procedure from WinXP and Vista).

It's not difficult, it's just a matter of knowing where to go and what to type to get it all set up.

Just search on the web about setting-up the environment variables in Java. You can find lots of articles about that.

You may or may not set the JAVA_HOME variable depending on your needs. Adding the jdk's bin directory to your PATH is sufficient to make you compile and run java programs from your command line.
Some applications expect a JAVA_HOME to be set and if you have such applications then you have to set it.

So in general, you need to set the JAVA_HOME variable at the moment as r035198x says. Why don't you just give a try with a simple Java code about this, weather you can compile a Java class without this setting or not.
