Classpath does not work under linux

The classpath syntax is OS-dependent. From Wikipedia :

Being closely associated with the file system, the command-line Classpath syntax depends on the operating system. For example:

on all Unix-like operating systems (such as Linux and Mac OS X), the directory structure has a Unix syntax, with separate file paths separated by a colon (":").

on Windows, the directory structure has a Windows syntax, and each file path must be separated by a semicolon (";").

This does not apply when the Classpath is defined in manifest files, where each file path must be separated by a space (" "), regardless of the operating system.

Try changing the semi-colon to a colon.

The CLASSPATH separator is platform dependent, and is the same as the character returned by java.io.File.pathSeparatorChar.
