RE: Splitting ApplicationResource.properties
Becky, Attached is an extension of ActionServlet that I wrote which loads multiple resource bundles based on a properties file that specifies everything to load. This may not be exactly what you want, but it might give you some good ideas - Hope it helps - Margaret -Original Message- From: Becky Moyer [mailto:[EMAIL PROTECTED]] Sent: Monday, January 21, 2002 3:30 PM To: [EMAIL PROTECTED] Subject: Re: Splitting ApplicationResource.properties So, from Martin Cooper's post at http://www.mail-archive.com/struts-dev%40jakarta.apache.org/msg04548.html, I gather that while there is an apparent assumption that each application has a single source of message resources in both Struts 1.0.x and the latest code, I can infer there is a way around it?? The new subapp concept looks pretty cool. But does that mean you can install subapps on the fly, while your servlet engine is running? My ActionServlet has a set of pages that allow developers to upload an almost-war file (that has a struts-config.xml but no web.xml file) and it's read in and available immediately, all classes are loaded in... things are put in set places. This allows new sections of the site to be added without reloading tomcat. Anyway, back to the topic at hand, I am still confused. With Struts 1.0, can I add new messages without restarting (as I can add ActionMappings, etc, without restarting)? I have been trying to look at the Struts code to see how it's done now, and I am just not seeing a way I can add my messages.

RE: How to handle a PopUp Form from another Form?
Nimmi - In doing something similar to what you want to do I did the following: 1) Create javascript function to open a new modal window (I am only concerned with supporting IE5.5, so using #showModalDialog works for me 2) create the link using plain ol' html, with an onClick handler that points to my javascript function. Build the url to pass to the function using html:rewrite which allows you to specify your forward, etc as you are currently doing with the html:link tag 3) For the action that I open in the popup, I define both success and failure pages. The success page contains javascript that looks for the opener window and refreshes it, then closes the popup window. 4) using the #showModalDialog is the most effective way that I have found to prevent the user from going back to the opener window.

It is an indexed link. I already know how to get the indexed link to include the part number. What I want to do is: This link should point to an action class, say partInfo.do, which retrieves the complete information about that part and puts it into an ActionForm and then forwards to a JSP in a NEW window(with no location bar,no tool bar,etc.)on top of the originator window. User submits to this ActionForm have to follow the normal ActionForm features, i.e., bring back the part form screen in case of actionerrors. And If the update is successful then the part changes are to be saved to the database and the popup window closed and user allowed to continue work on the originator window Until the user has successfully updated the data and the popup window is closed, he/she should not be able to get to the originator form.

RE: Reflection vs. Direct Method Call

I would be interested in hearing the differences for different Java implementations (I have heard that JDK 1.4 will be making huge improvements in this area) because I have heard that there can be significant differences. The application I am considering using Struts with would require large amounts of numerical data to be posted through the introspection and therefore if introspection performance is a problem I would have to choose another framework or roll my own. Thanks for any help, Kevin -Original Message- From: Andreas Amundin [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 26, 2001 2:50 PM To: '[EMAIL PROTECTED]' Subject: RE: Use of form beans - design issue... First let me preface with the fact that I have been dabbling with struts for about 6 weeks, so please take what I say with a grain of salt. And anyone else out there please correct me if I am wrong. See my inserted replies below. From: Burleson, Thomas [mailto:[EMAIL PROTECTED]] snip Currently -- as I understand it -- the ActionForm (bean) is populated by the ActionServlet using introspection. And the Bean is then used by the Action (handler) to modify/update the business layer or model data. Then the actionForward is used to indicate which JSP the Servlet should forward/dispatch to. The page (which could be a different JSP page or the same used for the request) then searches for the ActionForm (bean) and creates one if it does not exist in the request scope. This is where my understanding differs. As I understand it the ActionForm is created by the JSP if none exists. As far as I know it is possible to directly load a JSP page with a form without invoking any pre-processing action servlet. So (finally) here is the issue: The controller and handler uses a dumb bean to modify the model (MVC). Cool! But to gather information for use on a JSP, the bean must know how to gather that data from the business layer (model). BAD!! Following your understanding of how things work I completely agree with what you are writing above. However, let me now state that I don't think beans used in a JSP should ever have any dependencies on the model. IMHO beans for use in JSPs should be dumb holders of information. They are the input and output parameters of the JSP. To populate beans for a JSP a pre-processing action servlet should use model classes or EJB entity beans. The action servlet controls how information from the model is propagated to the view. The handler should configure the bean BEFORE dispatching to the JSP. This way, the bean remains dumb and the handler centralizes all knowledge of the business layer. Exactly. Struts seems to use 2 different patterns/approaches: the incoming processing is very different than the processing used during display of the JSP. I would say Struts have an approach for incoming, from the form, processing that automatically populates the form bean with the information from the form. For the processing during the display of a JSP all that happens is that the form bean is created if one cannot be found. The found form bean, newly created or not, is used to populate the default values of the form. I hope this explanation makes sense. Andreas
