Re: second thread call to stateful session bean

[Mirchandani, Vishal]

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
