how to pass input value to <s:url> call

Question

I want to pass input area value in s:url using s:param (where I marked as 'xxx') . Here is my code

    <s:url id='getName' action ='getNameAction'>
       <s:param name="userName" value= 'xxx' />
    </s:url>

the input jsp code is

    <textarea id="user" name="userName" rows="10" cols="80"></textarea>
    <sj:a id="getNameHref" href="%{getName}" targets="commands" onSuccessTopics="complete" indicator="indicator"  button="true" >Show Me</sj:a>

how can I pass the textarea value to s:param tag in s:url call ?

to solve it, I use ajax .getJSon() instead.
