Setting the classpath for JAR files

while setting the classpath a single dot (.) means current directory. As you jar files are in current directory, you just need to go to your current directory using cd command in DOS prompt, then use

set classpath = .;filename.jar;another filename.jar

Here . represents current directory and semicolon separates each classpaths.

You can even set classpath of more than one jar files using wild card character * which can be read as all.
