My text field and the link are defined inside a HTML
form and I do have the html-el and the JSTL tag
libraries. Everything else worked fine except passing
this text field value as a c:param via the c:url link.
When I submit the form, the browser address bar shows
searchFirstName=
a blank is sent.
Let me post my code again. 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="${searchFirstName}" />
</c:url>
<A href=' <c:out value="${ascFirstName}" /> '></A>
and in my action class, I have
String firstName = request.getParameter(
"searchFirstName" );
I tried to print out the firstName in my action class
using System.out.println( firstName); I got a blank!
