Can I post information to a client from a servelt?

I have written a servlet program. I can request parameters from the client and use the variables in my servlet to output a new HTML page replacing the old page. I am wondering, is it possible to call a servlet from your HTML page, do some calculations and then post the new data to the existing HTML page from which the data came? I do not want change the page set up, but just change the contents of, lets say, a textbox. If I can, how do I do it?

Thank you for you help.
