refresh a part of a page using struts without using ajax

Guys, is it 开发者_JS百科possible to refresh a part of a page in struts without using ajax. kindly let me know.

You can add a JavaScript function to the page which loads a string from somewhere and assigns it to innerHtml of some element.

To invoke the function, either use a timer or call it when the user clicks on a button or a link.

If you need a more specific answer, ask a more specific question, please.
