Linux (actually all unix variants) use the colon (":") to separate jar files. Windows uses the semicolon (";").
And BTW, if you look closely at the usage message that was printed out, you would notice that...
-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
A : separated list of directories, JAR archives,
and ZIP archives to search for class files.
