sathish... what you came across is a transactional way to add a task on a queue.
Toby described how I do it too (without transactions). DatastoreServiceFactory.getDatastoreService().getCurrentTransaction() is a low-level API way of retrieving the current datastore transaction. If you add a task to a queue with the transaction, if the transaction fails, the task will not be added on the queue. The task will be added only if transaction commit succeeds. Are you trying to add tasks transactionally or just add tasks? If you don't care about transactions, do it like Toby showed. By the way, you will not be redirected anywhere. queue.add(...) is asynchronous and your servlet will exit. The url you're providing is to your task servlet web hook that will get executed at a later time.
