@MYYN - it's four to me, the first two are equivalent and the 'current directory' thing is too trivial and limited ;) — Andreas Dolk

There are three common ways to set the classpath:

define the environment variable CLASSPATH
add -cp argument to the java call
declare the classpath in a jar manifest file.

I recommend the second option. Just write a shell script or batch file that executes java with the classpath and the class containing the main method.

Simplest ways to set classpath

from the command line
from the environment ($CLASSPATH)
if your program is packed in a .jar, from the Class-Path: field in the MANIFEST.MF
