You can use full path of the jar file as an argument to "java"

String command= "java -jar /home/raj/Desktop/test.jar"; 
Runtime rt = Runtime.getRuntime();      
Process pr = rt.exec(command);

If you want to actually start a terminal window (rather than just executing the java process) you will need to launch xterm (or something similar) and tell xterm to run java for example

String command= "/usr/bin/xterm -e /home/raj/Desktop/java -jar test.jar"; 
Runtime rt = Runtime.getRuntime();      
Process pr = rt.exec(command);

Please refer following example .with list of arguments to java program.

Process proc = null;
try {
    String cmd[] = {"gnome-terminal", "-x", "bash", "-c", "ls; echo '<enter>'; read" };


    proc = Runtime.getRuntime().exec(cmd, null, wd);
} catch (IOException e) {
    e.printStackTrace();
}
