Progress Bar - Asynchronous Request Logic

[John Simpson]

Hello,
I have an issue that I have yet to find help on. I have a web application designed using Struts. One requirement of my application is for the user to click a link/button/image/etc. and a process begins to run. (for example a report is generated) While the process is running, a progress bar (animated GIF) also is displayed.

The problem is that the requirement also states that the user should have full access to the rest of the application while the process is executing. Once the process has finished, a notification must be sent to the user displaying a message that it has finished.

I understand my requirements, but what I is unclear to me is how to approach them. I have considered using an Ajax/Javascript request object, but even then I am limited in my navigation of the rest of the application. I know that my solution lies in my Struts business logic, but how should I implement it?

Can someone please help me?

Hello Merrill,

I have updated my profile, please confirm that the changes made are ok. Also, do you have any tips concerning my original post? I have been reading about the use of Threads/Queues to implement such functionality, however, the overall view of how this is implemented is still unclear to me. Please reply...
