The fundamental concept is that an Action can, in fact, create the response itself, if it wants to, and then return null from the perform() method to indicate to Struts that no forwarding needs to be done. Within the action, you would call response.getOutputStream() and= write the bytes of your image (after doing any necessary conversion and= setting the correct content type). In a JSP page that references the dynamically created image, you would = say something like: html:img page=3D/createImage.do/ and this will create a hyperlink to the URL that will dynamically creat= e the image when the page is displayed. Like all img tags in HTML, the= image is loaded from a separate request (most browsers will initiate multiple requests in parallel if you've got multiple images, so be sure= your session data is thread safe) as the calling page is being displaye= d. Alternatively, you might consider creating a separate servlet whose purpose is to create the dynamic image. Code very similar to what you'= d put in the action would be used to create the image.

user-specific default-values of html-formulars
Hi, I want to save user-specific default-values of html-formulars. I think the best way is to put the ActionForms in a synchronized HashMap (user as key) and save this in a file when a user specifies new default-values for the formular. In the ActionForm-constructor I will check the HashMap if default values for the formular are present and set them. Is there any other meaning? Does anybody make it so?
