Re: Must everything go through an action?...
Thanks so much for your answer. While I do understand everything that you point out, I was wondering if you might have some links to documentation on some of what you have talked about. I almost feel like this is a grave difficency in the struts framework as to not a standard way of dealing with the View Helper pattern. You know, it would be wonderful to have an index page with dynamic content coming from a java bean and not have to initialize that java bean by forwarding to an action that does so from a welcome page. In other words, just have every jsp page be linked to a View Helper so the View Helper does its work before displaying the page that is called. From the J2EE pattens book, it seems to suggest that course of action. (Of course, I could just be reading in what I want to). Anyway, thanks again! Keith - Original Message - From: Ted Husted [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Sunday, October 05, 2003 7:16 AM Subject: Re: Must everything go through an action?... The current trend is to define two sets of Actions. One set represents the business actions, the client stories. This Action interacts with the business layer and, based on what happens, selects the next View. Back in the Struts 0.5 days, the ActionForward would often points to a server page, so the Action would, essentially, forward directly to a JSP. Most of us now find it convenient to create a second set of View Actions. These Actions work as page controllers. Instead of forwarding to the JSP, we forward to these Actions instead. These Actions can then prepare the request with whatever chrome the page may need. It's a good practice to define an ActionMapping for every presentation page in the application, whether it's a server page or HTML, local or remote, even if it just forwards out to a page. If you need to add an Action class later, or switch in a server page for a static page, you can do that without changing anything else. In Strut 1.1, I find it useful to separate the business Actions and the view Actions into separate configuration files, and may give the View Actions their own virtual path. So there might be a /SelectPermitAction and a /view/SelectPermitAction. There is talk of adding a specific extension point for a view Action as part of the ActionForward construct, but AFAIK, no one's rolled up their sleeves and given it a try. This would save a trip through the container, and simplify cases where you want to redirect to another business Action. HTH, Ted.

Design Question...
Sorry if this is a little off-topic but it has to do with Struts because I am using struts for my web app. I have been reading about the View Helper pattern off the sun website and have two ways of thinking about implementing this pattern. First is the way that I currently have setup: Use an action to call a method on the Delegate. The Delegate create a JavaBean (Value Bean) that has the data that I need for the particular page that I am trying to view. The Action then sets that view in the session scope (tried request scope, but it didn't work) and then forwards to a jsp. The jsp then uses the java bean from the session scope to fill in data for the webpage. Now for the other way that I was thinking of: In the jsp page that I am trying to view, first create a new instance of the JavaBean by calling jsp:useBean tag. Then, use the JSTL tags to set parameters that could be passed in from the url. The JavaBean then does the calling of the Delegate to get the information that it requires (potentially in several method calls). In the jsp, using jsp tags I call the getProperty to get the information needed to fill in the data for the website. In other words, the getProperty invoke the JavaBean to call the Delegate to get the information that is needed. The way I see it, there is a trade-off between the two ways of doing this. The first way does not allow (easily) for the adding of request parameters to the url to change the view. The second way, though, could potentially involve many expensive RMI calles to the EJB Container, which is where I am getting the data for the web pages. I would appreciate any of your thoughts as to how best to proceed. Thanks in advance for all your suggestions!

Design question...
I have a JSP page that contains entries from a database. I am getting the items using a DTO that is passed from a session EJB. What I would like to be able to do is to specify a parameter in the URL named offset that when changed would display the next results from the database. Couple of questions... Would it be considered presentation logic to perform the action of getting the DTO from the session bean within the JSP page? I really don't want to do it that way because I'm trying to keep the layers as separate as possible. So, if I don't do it that way, I will have to use Action classes and html:links that can pass the parameter to action class? My real question is what is the best way of dealing with EJBs in the presentation layer? I know that I have to get a DTO of the information that I want, but usually the methods of the DTO take parameters that I can't pass to the DTO in the JSP page. I have read over and over the Oreilly Struts book but it still is confusing me. Thanks for any help!

I am looking for more than the basic examples you normally find as they do not help given the complexity of the application I am working on. Secondly, what strategies does one use when deciding on how to implement the ActionClass to Session Bean Inteface? I am thinking along these lines: Create a 'Client Helper Interface' that defines all the business methods that your application will require. This Helper class will form the interface between the ActionClasses and the Session Beans. The ActionClass creates a 'Client Helper Interface' object and calls the relevant methods within this interface. The Client Interface then creates a Session Bean that implements the Client Interface. The Session Bean creates the Entity Bean that opens the database connection and returns the relevant data back to the Session Bean. The Session Bean returns the required information back to the Client Helper Interface. The Client Helper Interface returns to the ActionClass Should you have a separate Helper Interface for each Session Bean? many thanks yan KickStartESolutions - Intelligent Web Services [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Also, with the validator framework, does this just apply to basic (non model based) validation? _ Find a cheaper internet access deal - choose one to suit you. http://www.msn.co.uk/internetaccess - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Keith Pemberton [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Dispatch Action help...
Hi all, I have a webform that I am trying to create and I have run into a huge problem. So, at the top of the form I have the action specified and underneath I have defined the inputs using the struts taglib. Now, I can submit the form to the Action just fine and all the ActionForm is filled in with all the correct values. I want to be able to include a list of dynamic links with the form information. I have a html:select defined and above that to html:text input fields. Also, I have two buttons (Add and Remove) that I would like to specify the Actions on those two buttons to add an entry to the html:select or remove a selected value in the html:select field. So, here is what I have tried so far. I started using JavaScript to dynamically add the content from the two input fields to the html:select box. When I submitted the form, though, I would only get a String[] from the html:select box that was the values of the entries (not the values and the labels). Now what I am trying to do is to use a DispatchAction class and specify a html:link around each html:button that points to the DispatchAction class with a parameter that says which action to perform. When the program goes to the DispatchAction class, the ActionForm that I specified in the struts-config.xml file is not populated with the fields from the webform. I have tried also to figure out some way to add the parameters onto the request line but the only way that I can do that is using the onclick javascript method and specifing document.location = '/admin/EditReference.do?action=addOptionrefTitle=' + refTitle.value + 'refLink=' + refLink.value. Now, this works fine for add the stuff to the html:select because I have a bean in the session scope that the refTitle and refLink are being added to. But, when the DispatchAction returns to the webform the other values in the webform do not show anymore. What I figure is happening is that the webform is not getting populated because I haven't actually submitted the form when doing the Add and Remove actions, so therefore that information is not re-put into the webform when the DispatchAction returns to the webform. Anyone know what else I can do? Sorry if this was confusing. I can submit code if it would make things clearer. Any help is very much appreciated! Thanks in advance!
