When the browser executes the <img src="GetImage.do?param1=blah¶m2=xyz"> tag, it is basically giving a saparate request to your action class that generates the image. Notice that the action class returns null, which means that the action class will render the response itself and will not forward to any JSP page. The remaining protions of your JSP will be generated by other Action Class forwards as usual. >> >> Hope this helps to understand better. >> >> Thanks and Regards, >> Thomas Joseph >> >> Kott Software Pvt.
