Hi, I am developing a web application with servlets, stateful sessionbeans, CMP beans, and oracle 8.1.6. In our application we are trying to generate reports dynamically. To generate report dynamically it takes minimum 1min. Meanwhile (when the report download is in progress) if user clicks any link or any other button with in the same form that is provided on the webpage, I am getting the following error. What is the reason for this? How to solve it. I cannot restrict users not to click the other links on the webpage.
