I must have done someting wrong.

I tried to pass the value entered in a textfield:
<html-el:text property="searchFirstName" />

to a link this way:
<c:url value="/admin/sortUsers.do" var="ascFirstName">
    <c:param name="searchFirstName"
value="${searchFirstName}" />
</c:url>

and in my action class, I have
String firstName = request.getParameter(
"searchFirstName" );

I tried to print out the firstName, I got a blank!

Please advise what went wrong.

JSP tags are processed *on server*. For your setup to work you need to
submit a pag with <html-el:text property="searchFirstName" /> to the
server first, read value from request parameter and stick it into
appropriate scope under "searchFirstName" name.

Then, when you forward to JSP from your action, JSP/servlet engine
will process JSP tags, still *on server*. It will read
"searchFirstName" from servlet scope and write out its value into
generated HTML markup. Then resulting HTML page will be sent to
browser.

If you want to do the whole thing on client, use HTML form and submit
it with GET method. This way form fields will be appended to "action"
URL, exactly as you wanted.
