I haven't a mac computer to test the script, could you try to run this command, it's a standard command of java, please enter the installed dir first , then run the command in one line:

java -cp lib/fcserver.jar;lib/log4j.jar;lib/jdom.jar;lib/xerces.jar;lib/mysql.jar;. com.topcmm.jchat.MainServer

is that work ?
