You need the path of the plugins directory of your local GATE install  So if Gate is installed in   home user GATE Developer 8 1   the code looks like this   System setProperty  gate home     home user GATE Developer 8 1 plugins      You don t have to set gate home from the command line  You can set it in your application  as long as you set it BEFORE you call Gate init
