Below is an excerpt from an Java World article circa 1999 (author: mailto:[EMAIL PROTECTED]) describing the difference between Model 1 vs. Model 2.
The early JSP specifications advocated two philosophical approaches for building applications using JSP technology. These approaches, termed the JSP Model 1 and Model 2 architectures, differ essentially in the location at which the bulk of the request processing was performed. In the Model 1 architecture, shown in Figure 1, the JSP page alone is responsible for processing the incoming request and replying back to the client. There is still separation of presentation from content, because all data access is performed using beans. Although the Model 1 architecture should be perfectly suitable for simple applications, it may not be desirable for complex implementations. Indiscriminate usage of this architecture usually leads to a significant amount of scriptlets or Java code embedded within the JSP page, especially if there is a significant amount of request processing to be performed. While this may not seem to be much of a problem for Java developers, it is certainly an issue if your JSP pages are created and maintained by designers -- which is usually the norm on large projects. Ultimately, it may even lead to an unclear definition of roles and allocation of responsibilities, causing easily avoidable project-management headaches. I believe sun originated the terms Model 1 and Model 2 in this context. ----- Original Message ----- From: "Galbreath, Mark" <[EMAIL PROTECTED]> To: "'Struts Users Mailing List'" <[EMAIL PROTECTED]> Sent: Monday, April 29, 2002 11:20 AM Subject: RE: Difference between MVC and MVC2 architectures > There's no such thing as "MVC-2" (it's "Model 2") and it's not an > architecture; it's a design pattern.
