    runtime.getruntime.exec in applet



    Can I call Runtime.getRuntime().exex(cmd) in an applet? If yes, how to
    do it?
    I wrote an applet which should allow user to run some program on the
    server. however I always got an "appletsecurity: checkexec " error.

    Here is my code :

    init(){
    button4.addActionListener(this);
    }

    ActionPerformed(e){
    if (e.getSource() == button4){
    runScript() ;

    }
    }

    public void runScript(){
    try(Runtime.getRuntime().exec(script) ;}
    catch(exception e){
    system.err.println(e.toString) ;
    }
    }

    Hi,
    U have to go for java security permission.
    In that u have to specify the permissions for
    some operations u r going to perform.
    Use security model of java.
