Re: How do you mimic the 'a href' functionality in Struts?
The "action" attribute of the html:link tag and the "path" attribute
of the action element should be identical.
Note that the value of the "paramName" attribute ("viewcontactlist"
in your example) is not a string literal, but rather the name of a
bean in some scope (page, request, session, or application) which
will be looked up and converted to a string as the value of the
parameter. In your case, since you specify paramScope="request", the
tag will specifically call "request.getAttribute("viewcontactlist")"
to get the value.

"ContactForm" is the FormBean (explicitly defined elsewhere in the struts-config.xml file) that will be passed to the ContactAction class.

At first encounter, the distinctions between the various link
destination attributes can be a little confusing -- but you probably
don't want to use href in this case.
If you have a specific action mapping called "/ContactForm" then you
should use 'action="/ContactForm"' You would generally only want to
use "href" when you were linking outside of your web application --
the other three provide dynamic URL rewriting to prepend the
application context path so that you can deploy the same web app
under different context paths without having to change your JSPs...
(Other tags like html:img provide similar rewriting...)
The below is copied from the docs for this tag:
The base URL for this hyperlink is calculated based on which of the
following attributes you specify (you must specify exactly one of
them):
* forward - Use the value of this attribute as the name of a global
ActionForward to be looked up, and use the
application-relative or context-relative URI found there.
* action - Use the value of this attribute as the name of a Action to
be looked up, and use the application-relative or context-relative
URI found there.
* href - Use the value of this attribute unchanged.
* page - Use the value of this attribute as a application-relative
URI, and generate a server-relative URI by
including the context path and application prefix.

Re: How do you mimic the 'a href' functionality in Struts?
Yes I am going to pass the same param to the link every time.
This is what I have replaced the link with.
I am not too sure if I should be using the href
property to call my ActionForm class.

"Struts Users
Mailing List"
In general, you use the tag
http://jakarta.apache.org/struts/userGuide/struts-html.html#link
For the destination of the link, it takes one of four attributes:
forward, action, href, or page.
The mechanism for specifying a single parameter for the link uses
these attributes: paramId, paramName, paramProperty, paramScope
The value of paramId is the request parameter name. In your HTML
sample, then, this would be "page", although in your ActionForm, this
would probably be "pageName". (You probably want those to be
consistent with each other.)
You can specify the value for the parameter with the appropriate
combination of paramName, paramProperty, and paramScope, with
semantics analogous to "name", "property", and "scope" in the various
bean tags.
If you need to specify multiple parameters, this is done with a map
whose keys are parameter names and whose values are the values to be
put in the URL. See the docs for more details.
However, I'm guessing from your example link that you'd pass the same
parameter in the link every time -- that is, you'd always want the
text "Contact List" linked to the same URL. In this case, the better
Struts "way to do it" would be to define different action mappings
for each of the various parameters you would pass. This leaves you a
lot of future flexibility about how the functionality is provided.
If necessary, you could write a separate Struts Action class for each
mapping, or you could use one action for several mappings and use an
action mapping "parameter" to dispatch execution to a
parameter-specific method inside the action.
Hope this helps.

Hi,
I have the following link in my JSP page:
Contact List
I want to mimic the above using Struts JSP tags(I don't want to use
a SUBMIT button). However, I want to call my ActionForm class
instead of the servlet and I would like to set the value of the
param 'page' to 'viewcontactlist' for my ActionForm class so that my
Action class can use it.
Is it possible to do this?
Here is my ActionForm implementation:
import javax.servlet.http.HttpServletRequest;
import org.apache.strus.action.*;
public final class ContactForm extends ActionForm {
// page parameter from the CDS menu
private String pageName =null;
public String getPageName(){
return (this.pageName);
}
public void setPageName(String pageName){
this.pageName = pageName;
}
}

Yes.
Your href attribute can point to a JavaScript function that sets some hidden form
variables then submits the form. It would look something like this:
function submitFunctionForYou(lType) {
document.yerForm.elements["page"].value = lType;
}
