The question is that I don't need to forward to a JSP. The controller takes the HttpServletResponse and writes in it, and that is the response to the user. Before that I put the image as an attribute in the request, and in a JSP template I recovered it form the request, and wrote it, but the tomcat always said that the Output stream had already been closed.
Is there anyway to return a image to the user using a controller without using a JSP? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Benedict Sent: Tuesday, August 21, 2007 18:18 PM To: Struts Users Mailing List Subject: Re: Tiles: definition without path I don't understand why you haven't provided a path attribute on the definition.
