I think you would benefit much to move to a real MVC architecture. Go to
jakarta.apache.org and look at Struts. Read the docs, and use it. Its a
great tool, its free, its open-source, and it will allow you to "properly"
design good MVC development. You wont be submitting jsp pages back to
themselves anymore. :)

>
> their descriptions ) from a servlet "
> ConnectionPoolServlet.java " to a
> Jsp file " Display.jsp".
>
> The Jsp "Display.jsp" is displaying only 10 images in the
> first page & then
> showing a
>
> link " NEXT".
>
> This link is again calling the same Jsp file " Display.jsp "
> for displaying
> the next
>
> 10 images.

> A part of the code of " Display.jsp " file is given below:
> **********************************************************
>
> <%@ import page = "ConnectionPoolServlet" session = "true" %>
>
> <html><body>
>
> <%-- Then comes the code for the display of the images &
