Captcha

[Rohitash sharma]

I have created a programme based on 'captcha'.It is working but i want to add one essential feature. I want to add a link on the same page that if any one click on that link captcha image should change but not whole page should be refreshed

Please give me guidance

Use Ajax. Not a particularly Struts-oriented question, though--if you're using Struts 2 you might be able to use the provided Ajax tags (although we're probably going to deprecate them as of S2.1.3).

But sir it is not possible that if we click on that link then it calls a servlet and we create another image produced by that servlet and
we include that image in page.

That's why I said to use Ajax, so it doesn't refresh the entire page.
