You can refresh the page, but that would probably be annoying to the user,
not to mention that data entered on fields will most likely be lost. Using a
div you can update just the part of the page that is important. Using the
div tag in struts:
theme="ajax"
href="%{ajaxTest}"
updateFreq="3000"/>
that will make your div reload the content from "AjaxTest.action" every 3000
milliseconds. There are many frameworks available, so you can pick one that
fits your needs. For simple scenarios, the div tag will do.
