The problem is that requests for the static content go to the dispatcherServlet, because it’s mapped as <url-pattern>/</url-pattern>. It’s a very common problem in applications with “RESTful” URLs (that is, without any prefix in the DispatcherServlet mapping). There are several possible ways to solve this problem: Since Spring 3.x the preferred way to access static … Read more
N-tier architecture usually has each layer separated by the network. I.E. the presentation layer is on some web servers, then that talks to backend app servers over the network for business logic, then that talks to a database server, again over the network, and maybe the app server also calls out to some remote services … Read more
Seeing you are NEW to ColdFusion what I would do is pick ONE FRAMEWORK and stick to it. At first it will be hard you will have problems and you will be tempted to drop the Framework you have chosen but don’t do it. After you have mastered one framework then you can learn the … Read more
How about this – off the top of my head, hopefully it works for you. MVC can be metaphorically related to a TV. You have various channels, with different information on them supplied by your cable provider (the model). The TV screen displays these channels to you (the view). You pressing the buttons on the … Read more
The service layer can be interpreted a lot of ways, but it’s usually where you have your core business processing logic, and sits below your MVC architecture, but above your data access architecture. For example, you layer of a complete system may look like this: View Layer: Your MVC framework & code of choice Service … Read more
You might want to take a look at what Martin Fowler has to say about MVC, MVP and UI architectures in general at Martin Fowlers site.
It’s a bit tough to give you the “right” answers, since some of them deal with the specifics of the framework (regardless of the ones you are working with). At least in terms of CakePHP: Yes Anything that deals with data or data manipulation should be in a model. In terms of CakePHP what about … Read more
Gee, Brian, I wish I had seen your question sooner. Since it’s pretty much my “invention” (for better or worse), I might be able to help. Inserted: The shortest possible explanation I can make is that if normal execution is like throwing a ball in the air and catching it, then differential execution is like … Read more
MVC/MVVM is not an either/or choice. The two patterns crop up, in different ways, in both ASP.Net and Silverlight/WPF development. For ASP.Net, MVVM is used to two-way bind data within views. This is usually a client-side implementation (e.g. using Knockout.js). MVC on the other hand is a way of separating concerns on the server-side. For … Read more
A Data Transfer Object is an object that is used to encapsulate data, and send it from one subsystem of an application to another. DTOs are most commonly used by the Services layer in an N-Tier application to transfer data between itself and the UI layer. The main benefit here is that it reduces the … Read more
