Well you can set some environment variables like JAVA_HOME and include it in the PATH environment variable like %JAVA_HOME%\bin.

But you do not want to create an environment variable called CLASSPATH. Why? Because it is considered bad form. What happens is this, there are lots of applications that need Java out there, and if you have your CLASSPATH set, then it might make those other programs not work, and the other way around.

So your classpath should be set at "runtime" meaning at the command line when you start up your app. As a command line argument for Java.exe like "java -cp"

Or if you open a seperate command window, you can set a local to that command window variable.

So for j2ee, just when running your app have java -cp somewhere\j2ee.jar

Good Luck

Create a *.bat file that set the classpath, compiles all java files and runs the app.

Software development is risky.
I agree. Here's the link:
