Hi,
I follwed the u r suggestion for appending the result of web page to another
webpage. Here I have to append the HTML content generated by ItemServlet
class to the Html generated by the PresentationServlet. I have to add the
HTML generated by the Itemservlet for 10 times and return the resultant HTML
to the browser
Could u please help me out,
This is an example I got in the Internet and I modified a little bit.
Thanks,
Sampath
