The short answer to this is that you don't - Struts does all the work for
you.
If the submitted query string contains 'mode=foo', then Struts will call
setMode("foo") on your form bean before your Action's perform() method is
called. You can access the value using your form bean's getMode() method.
If you need to set up 'mode' as a hidden field so that 'mode=foo' is always
submitted, then you only need:
<html:hidden property="mode"/>
When the JSP is processed, Struts will call your form bean's getMode()
method and use the result to generate the 'value' attribute of the <input>
tag.
Hope this helps.
