Thank you for helping me to learn different ways to
construct a web link while passing a number of
parameters along with it.
Those hyperlinks forward a request and parameters to
another servlet action. In this servlet action, do I
receive those parameters in an usualy way?
String sort = request.getParameter("sort");
String order = request.getParameter("order");
String offset = request.getParameter("offset");
Different Ways of Constructing a Hyperlink:
<c:url var="listThreadsUrl" value="listthreads">
<c:param name="sort" value="${sort}"/>
<c:param name="order" value="${order}"/>
<c:param name="offset" value="${offset}"/>
</c:url>
<a href='<c:out value="${listThreadsUrl}"/>'>
Click Me
</a>
Depending on how your Actions are setup you may be
able to do this:
<html-el:link action="${listThreadUrl}">
Click Me
</html-el>
James Mitchell gave this example a few weeks ago:
<jsp:useBean id="myLinkParams"
class="java.util.HashMap"/>
<c:set target="${myLinkParams}" property="id"
value="${dto.id}"/>
<c:set target="${myLinkParams}" property="type"
value="edit"/>
...later down the page...
<html:link action="/manageUserAccount"
name="myLinkParams">
<bean:message key="edit.user.link.text"/>
</html:link>
