hey this wht i’ve written.. but iam not able 2 recover the original data in DB once i encrypt.. plz help.. its urgent

Did Google see the amount of risk here?

If hacked, someone can change the course of the talk and may led to very undesirable responses, forged wars to the max.

Remember IROBOT?

Only gotcha I’ve run into is that if you try doing multiple execute()’s in a single execution all that come after the first that times out will fail with the same error.

The problem is that the thread’s interrupted status is not reset. If you change the finally block in execute to be:

finally
{
// Stop the timer
timer.cancel();
// clear interrupted status
Thread.interrupted();
}

this will clear the interrupted flag for the thread, and allow you to execute a new process again.

thank

…….

code? lets say that one is for http and the other one for https. I am trying it but it doesnt seem to work

thanx in advance
