Calling JSP directly.

["Shabada, Gnaneshwer" <sh...@toysrus.com>]

Hi,
Was wondering if calling a JSP directly a good approach in struts or should
I always go through Action/Action Mappings. I have a situation where I have
a result list displayed in a table and each row has email icon which when
clicked should display a JSP where one can enter email text and preview the
email. So I thought I could directly call JSP using <html:link
page="email.jsp">. But I also want to send the "To:" email address of from
the row where it is clikced. Can I pass it as a request paramter when I call
the JSP directly or do I call an Action instead ?
If I can call thru JSP, how do I retrieve that email value in the next JSP??

Thanks for your help
Gnan

You CAN call JSPs directly, but it's not generally thought of as a good 
idea.  If you need to display a JSP and don't really need any 
functionality behind it, you can use a ForwardAction, which is a kind of 
Action specifically designed to just forward to a JSP.  This keeps your 
control layer involved.

In your case, you can do that and I'm pretty sure there's no reason you 
can't add the eMail address as a query string parameter, then access it 
through the request object on your JSP page.  However, I think it's 
probably a better design to have an ActionForm and an Action to submit 
to, forward to your JSP and access it through the form as you normally 
would in Struts.  Certainly will make your life easier later if you need 
to extend what's being done.

You *can* call a JSP directly in this way, but it is not generally 
considered to be the best approach.  It's better to always link to an 
Action class.  Even if you use the Struts ForwardAction 
(http://struts.apache.org/api/org/apache/struts/actions/ForwardAction.html), 
which doesn't do anything with the request except forward it to a JSP 
page, you at least have the option of adding a different Action class 
later without chaning any links.

That said, if you do want to link directly to a JSP page, the method you 
describe will probably work.  Review 
http://struts.apache.org/userGuide/struts-html.html#link to see some 
ideas on adding request parameters dynamically using the <html:link/> 
tag.  In your JSP page, you will be able to access these parameters as 
usual.

HTH,

Jeff
