Struts with Ajax combination

I am developing an application in struts framework , where i am trying to display some content to the div tag in jsp when a option is selected in drop down box in a <html:form>

i can do this in jsp using onchange=this.form.submit() but i dont want to use this method as it effects the performance of the page display,

So i want to know is there is any other process to develop it

Can any one tell me how to use ajax for this application

Please provide me the information,

Thanks in advance

There is lots of Ajax info out there, including examples and tutorials, for example Sun's Ajax page and Mozilla's Getting Started with Ajax. Wikipedia has a good section with links, and search engines will find you plenty more.
