Scott,

This happens when multiple requests are handled. Say if the user clicks the submit button twice. But from my end i do not wish to disable the button after single click. Instead i wanted the response of the first request alone to be displayed in the jsp. Any idea how to implement this?

Thanks,
Ram

When someone double-clicks a submit button or link, two separate HTTP requests are made. In most web clients (browsers), what will also happen is that the reply port on the client side attached to the first request will be closed and that will cause server responses for the first request to fail to transmit fully. However, the server doesn't know about that yet, so both requests will go through the request processor.

Which means that it's far more important to restrict what gets updated than what gets displayed. For one thing, if the updates are done right, it won't matter that the second request display is what the client will actually receive back.

Disabling the submit button can help, but for best results, the webapp should detect and discard redundant updates.

Some people, when well-known sources tell them that fire will burn them, don't put their hands in the fire.

Some people, being skeptical, will put their hands in the fire, get burned, and learn not to put their hands in the fire.

And some people, believing that they know better than well-known sources, will claim it's a lie, put their hands in the fire, and continue to scream it's a lie even as their hands burn down to charred stumps.
