Using the CLASSPATH environment variable. See http://faq.javaranch.com/view?HowToSetTheClasspath.

Setting CLASSPATH is problematic if not evil and best avoided. Instead add the required jars for your program to your launch script: java -classpath ...

Use the classpath argument to the JVM or set the environment variable just for one run. Frinstance I have no classpath in my environment by default, and this is a typical batch file for me ...

Another consideration when setting the classpath is if the class is in a package. Then you need to adjust the path so that it plus the package gives the complete path to the file.
For example if the package is agent and the file is at C:\files\region1\agent\pgm.class
then the classpath should be:
C:\files\region1\
When you execute you need the package as part of the name:
java agent.pgm
 
It is sorta covered in the JavaRanch Style Guide.
