Hi, this is the initial post of a series where i’ll be publishing some samples showing how to develop web applications with Java technology.
I’ll try to start with a very simple example and make some progress visiting several APIs/Application Servers from the JEE stack.
This post sample consists on three projects that only uses POJOs.
The adopted subject is an application with codename ‘staffgest’ with employee management APIs.
The adopted architecture consists on a base project -”staffgest-mdw” that has the middleware service layer and the persistence layer(very simple, in memory List).
Through our journey, i’ll be decoupling the persistence layer and the presentation layer for demonstration purposes.
I’ll deliver two sample projects – “staffgest-text” and “staffgest-mvc-jsp” having the presentation layer for -”staffgest-mdw”.
“staffgest-text” is a JSE console app and”staffgest-mvc-jsp” is a web app deployed on a embedded Glassfish server .
You can read more about Glassfish Embedded in here.
The proposed flow on the web application is:
- Visit – ‘localhost:8080/staffgest-mvc-jsp/new-employee.html’ , where a form to create an employee is showed
– submit form and “new-employee.jsp” is rendered
- Visit – ‘localhost:8080/staffgest-mvc-jsp/search-employee.html’ , where a form to search an employee is showed
– submit form and “search-employee.jsp” is rendered
Relevant code snippets:
‘staffgest-mdw‘ , ‘staffgest-text‘ , ‘staffgest-mvc-jsp‘ – are all maven projects, so it should be fairly simple to import and build it. First build “staffgest-mdw” and the run “staffgest-text” or “staffgest-mvc-jsp” through a main class ‘App.java’.
Hope it’s helpful for someone!
