Demonstration
Creating the domain model


Agenda

•  Web Architecture
•  Web Artifacts
•  Commands
•  Directory Layout
•  REST URI Mappings


Web Architecture

•  Controllers interact with Domain entities
•  OpenEntityManagerInViewFilter
•  "Open EntityManager in View" pattern
•  JPA EntityManager bound to the thread for the entire
processing of the request
•  allow for lazy loading in web views
•  original transactions already being completed
•  Service layer optional
•  used for business logic spanning multiple entities


Web Artifacts

•  Java & Aspects
•  Spring MVC @Controllers
•  Property Editors
•  JSPX
•  clear format and structuring
•  fully XML compliant
•  Spring JS & Dojo
•  client-side validation
•  form usability improvements


Web Artifacts (cont.)

•  CSS
•  flexible UI customization
•  Apache Tiles
•  flexible templating of jspx pages
•  Tags
•  reusable pagination
•  theme selectors
•  language selectors
•  URLRewrite Filter
•  simplification of URIs


Web Artifacts (cont.)

•  XML
•  configuration of various technologies
•  Spring MVC & WebFlow application contexts
•  Tiles configurations
•  web.xml
•  Properties Files
•  internationalization support via message properties
•  theming configuration


Roo Web Commands

•  Generation of Web artifacts
•  controller scaffold
•  generate a controller for a given entity
•  controller all
•  generate controllers for all entities without an existing
controller
•  controller class
•  generate a simple Spring @MVC controller with a post
and a get method


Demonstration
The Web directory


Web Project Directory Layout

•  All web-related artifacts in src/main/webapp


Web Project Directory Layout

Directory Purpose
/styles style sheets (CSS)
/images graphics
/WEB-INF/classes/*.properties theme configurations
/WEB-INF/spring/*.xml Web-related Spring application contexts
/WEB-INF/i18n/*.properties internationalization message files
/WEB-INF/layouts/layout.jspx Tiles definition for master layout
/WEB-INF/tags/*.tagx Tag libraries (pagination, language, etc)
/WEB-INF/views/**/* Tiles and other view artifacts
/WEB-INF/web.xml Web application context
/WEB-INF/urlrewrite.xml URL rewrite filter configuration


REST URI Mapping

Resource GET PUT POST DELETE
Create a new

the collection.
Update the Delete the
Member URI such as
Retrieve the addressed addressed addressed
http://domain.com/ Not used.
topping with id=5 topping with topping
pizzashop/topping/5
id=5. with id=5.
Member URI such as Create Form - returns
