Setting Classpath Variables 

Use

A classpath variable is a name-path pair.

The path of the classpath variable shows:

·        The current path to the directory from which several classpaths of the J2EE application start or

·        The directory which contains resources used, by the application.

The name of the classpath variable is used in the Project Options and Classpath Management windows for a fast reference to the classpath variable.

The classpath variables are useful for projects that you move from one location to another. In this case, you should only change the path of the classpath variable with the new location.
