runtime.getruntime.exec in applet

[jerry]

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.
