Re: second thread call to stateful session bean

Hey Ashwini,
In case you are not able to trade up the server operation, you can handle
the same at the client browser itself or at the event Handler, in case
you have one.

Method 1:
In your browser, have a transparent div. When the button is clicked,
activate the div(visibility:visible) with maximum zIndex. This way the page
gets locked . Or
also you can have a message on the div saying: "Please wait".
When you receive the response, hide the div again.

Method 2:
Also it can be done in your architecture layout. Say for instance the web
page(e.g. jsp) submits the request to a servelet which in turn calls the
other classes
or the EJB. In this servelet you set a flag for processing and in case the
flag is true. Ignore all user intercepts. After processing, set the flag to
true and the servlet
will start taking responses.

Method 3:
Try and handle the exception in the bean itself and kill the transaction.
But this is not an efficient method as the server should never get a call in
case a request is being
processed. So 1 and 2 should work out for you.


Warm Regards,
Vishal Mirchandani
