Answer 1

sorry for that , but the
Runtime runtime = Runtime.getRuntime();
          Process proc = runtime.exec(new String[]{"cmd.exe","/c","jar"});
          proc.waitFor();
int i = proc.exitValue();
this code was different from first one
and in case of Process if runtime .exec is succesful it is wainting for long time , in this case i want if the runtime.exec is succesful something should be returned
Regards
