You can setup a Cron Job.

make a shell script that runs it, then call it from cron.

#!/bin/sh

JAVA_BIN=/usr/java/j2sdk1.4.1_02/bin/java
CLASSPATH=/home/jamin/classes:/home/jamin/jbproject

$JAVA_BIN -cp $CLASSPATH name.of.some.Class -arg

Then edit cron.daily or monthly or whatever and add a line that runs the script.

How to edit CLASSPATH?
If my class is locate in /root/HelloWorld.class.

I assume that the .java file does not have a package declaration at the top, like

package com.me.my.thing;

because if it does you will (in the case above) have to put it in

/root/com/me/my/thing/HelloWorld.class

anyway just type (or add to a shell script)

CLASSPATH=$CLASSPATH:/root

then try

java HelloWorld
