Grails vs OpenXava

OpenXava follows Java standards:JSR-168/286: Portlets

JSR-303: Bean Validation

JSR-330: Dependency Injection

JSR-317: JPA 2

JSR-19: The classic EJB2 (optional)

The code is interchangeable with other Java frameworks

Grails vs OpenXava

No code generation:You have few code for all application lifecycle

You only touch the codes you write. No GSP, controllers or other generated code in your hands

Initial application is richer with OpenXava

Spring Roo vs OpenXava

No code generation:You have few code for all application lifecycle

How do you customize your app?

View annotations

Custom controllers

Custom editors

Custom views

Styles

View annotations

Tips for the render engine

High abstraction level

OpenXava annotations are for UI the same that JPA annotations are for DB

@View, @Tab, @DescriptionsList, @ListProperties, etc (there are 80)

Any possible case for a business application

Custom controllers

A controller is a group of actions

An action contains the logic to execute when a user click on a button or link

There are generic controllers for CRUD and Printing

We can refine these generic controllers

We can create our own controllers

Custom editors

Editors are the user interface elements used to view and edit the members of your entities

There are built-in editors for all the basic types, references and collections.

You can create your custom editors using JSP, HTML, JavaScript, etc.

Custom editor

Custom views

Instead of using the automatically generated UI you can create your custom user interface for any entity using JSP, HTML, JavaScript, etc.

Rarely needed, but useful

Styles

When deployed in a portal OpenXava portlets get the look & feel of the container portal

You can create your own style using CSS

From an iPad get the native iPad look & feel
