No, There is no submit button.
On the JSP page, the user can do various things like attach a
word document, change the drop down which changes the attachment. All this information is eventually stored in a bean.
So for e.g, when the user changes the dropdown, the form has to be submitted and control passes to the servlet. Since each dropdown value has a different attachment and it has to get the attachment number etc from the database.
So after each event, the form has to be submitted. But somewhere there seems to be a double submit happening for a single event since in the second submit, the request parameters are null. Its a small bug fix for which implementing AJAX/Struts might be a costly solution for us.
