[Reference] From. VM,. Do,. Action

I don't know when our web site has some. XX web pages. Anyone familiar with Java knows to use a new Servlet technology .. VM is a velocity application,. Do Is A struts application, and. Action is a webwork application. The detailed consideration is actually the extension of Servlet technology. By defining your own servlet, You can parse the extensions of different applications. It is indeed not a simple file extension, but a new open source inspiration. More and more open-source projects are entering our lives. What can we find from them.
JSP is a language that we are familiar with. It can directly nest Java code, script, and tag tags on pages. During the application process, we increasingly find that the nested business logic in the page view is not desirable. We need to use a new MVC Web framework. Struts uses JSP/html as the presentation layer through the extended servlet. webwork is a lightweight MVC application than struts. It extends the servlet dispatch mechanism to implement display through the Extended Tag provided by velocity to webwork tools, webwork2 is not only applicable to the web layer; velocity is a template framework that can be applied to the web layer or the application layer.
We believe that open source brings us more than just thinking. We can learn from it. We will have an impulse to create, and we will soon join the Open Source army.
