hi all,
I use java in windows xp and I want to execute  .jar files in my java
program i tried the next code but it didn't work.
no errors in compilation,and no exception when I run it ,yet my
des.jar file didn't run.

public class RunIt {
    public static void main(String args[]){
        String[] commands=new String[3];
        commands[0]="cmd.exe";
        commands[1]="cd C:\\Documents and Settings\\ASUS\\Desktop";
        commands[2]="java -jar des.jar";

        try {
            Runtime.getRuntime().exec(commands);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

although when I try: "java -jar des.jar" in the command line it works
fine
