In some cases, users will make special requests to the server. These requests allow Webform Server to update the computes in an active form, display enclosures to the user, or save a copy of the XFDL form to the user's computer. These actions are performed through the portlet/servlet:
Parent topic: Form operations
- The user makes a special request, such as clicking a button to update the computes in the form or to display an attachment. This request is sent to the portlet/servlet.
- The portlet/servlet receives the request and sends it to the Translator.
- The Translator interprets the request and takes the appropriate action. For instance, it may run an update on all of the computes in the form, or it may retrieve an attachment from the original XFDL form. The Translator then passes the information to the portlet/servlet.
- The portlet/servlet sends the information to the user. For example, this may be an updated form or a Microsoft™ Word document that was attached to the form.
