Since you want to change the value of a link based on what the user selects before clicking on the link, you must do this on the client side, not the server side, which means you must use javaScript.

The first thing you need to do is specify styleId="xxx" in your <html:link> tag where xxx is some unique identifier. This will make it easier to access the tag in javaScript.

You will next need to retrieve the href property of this object and change it according to your needs. The best place to do this would be in the onchange event of the combo box.

Supposing you wanted to append the value of the combo box as a parameter to the URL of the link, here's some sample code:

<script>
function changeHref(optionValue) {
var link = document.getElementById('myLink');
link.href = link.href + '?option=' + optionValue;
}
</script>

<html:link styleId="myLink" action="/myAction" />
<html:select property="mySelect" onchange="changeHref(this.value);">

This is a bit simplified. In the real function, you'd want to insert code to remove the ?option parameter from the href string before adding it. This would allow for the case of the user selecting first one option, then changing her mind and selecting another.
