Hi,
I have one classic HttpServlet for dynamically rendering an image from given
(database retrieved) data. Actually this servlet takes data from session
(previously retrieved from database and put inside session) and renders the
image. Since this is not Action but classis servlet it is mapped in web.xml
as '/ImageServlet'. When I have in my html/jsp tag like this one '<img
src="/ImageServlet">', I get wanted image. That's all fine.
Now, I'd like to avoid using session for this purpose and like to take data
for ImageServlet from request but I see that request data is not forwarded
in additional browser's request for image. When I originally request page
like 'page.jsp?id=1' this 'id=1' is not forwarded in request for image data
'<img src="/ImageServlet">' from page.jsp! That's why I use session. Is this
only possibility? Can I use '<html:img src=.../>' or '<html:img action=...>'
and expect original page request to be forwarded to image request as well?
On the other hand, how to create Struts' Action that could be used for the
same purpose of rendering image? In classic HttpServlet there are methods
doPost/doGet which do not return any data (void) but Struts' Action expects
ActionForward as a return value. What might be the return value in case that
this Action is used for rendering image and called inside '<img
src="/ImageAction">' or '<html:img action="/ImageAction"/>'?
