Calling JSP directly.
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??

Re: Calling JSP directly.
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.

Re: Calling JSP directly.
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. -- Frank W.

RE: Calling JSP directly.
OK. I created an Action class (DisplayEmail) and called it instead of the ForwardAction class. In my action class I am setting the values in the ActionForm (EmailForm) and displaying the JSP. EmailForm has fromEmail, toEmail, subject and emailBody as the attributes. Works fine until here and gets the fromEmail and toEmail values and displays on the JSP using bean:write tags. Now, when I add Subject and Email text and hit send, it goes to a diff Action Class(SendEmailAction) and when I try to get the fromEmail and toEmail from the ActionForm (EmailForm), they return null. I have the EmailForm set to request scope in the config file for this action. I thought I should see those values in the ActionClass but no luck. Can anyone point out if I am doing anything wrong. Does the ActionForm retrieve values if I use bean:write tags in the previous JSP or should they be alwatys input tags.. Let me know if you need more info.

Thanks for your replies guys. I implemented the ForwardAction class as you suggested and it works. But I ran into another problem Like I said I am displaying the value from the request scope as below. td%=request.getParameter(email)%/td This displays what I want. But can I set this to my ActionForm for this JSP, so that I can retrieve the same value in my Action Class and use it for soemthing else. I tried this but didnt work: tdbean:write name=emailForm property=%=request.getParameter(email)%//td is there any other way that I can set this value to an ActionForm using bean tags Thanks again -Original Message- From: Frank W.
