Re: Displaying multiple images using servlet or JSP into html table
Please read post 2 and post 5, and the advice given therein regarding how best to ask questions to get the help you seek in an efficient manner. You other thread (3rd) thread has been removed, creating more will not get you help any sooner, in fact it will irritate moderators who must deal with them appropriately, and who will then consider taking further action.
