You need to install the java runtime environment or standard edition from www.java.sun.com version 1.4 or above. At the time of this writing version 1.5 beta was available, please note that the server was not tested with this version. To start the server after installing java use the exe file on Windows, app file on Mac OS X, for other OS from the command line “javaw –jar sabbybot.jar” or “java –jar sabbybot.jar”, or just double-clicking on the jar file will also work. If your server has hundred of thousands of file and you are getting out of memory error you might want to use the –Xmx to increase the total amount of memory available to the virtual machine. For example, starting on a windows machine with the virtual machine using a maximum of 128MB of memory would give this command “javaw –Xmx128M –jar sabbybot.jar”. Please note that this should only be important on non Windows/Mac OS or when starting the server from the command line.
