XEO Framework Primer

Welcome to the XEO (eXtensible Enterprise Objects) Framework's Primer, the following chapters will give you an introduction to the XEO framework and its basic concepts as well as guide you while creating your first XEO Application.

Introduction

XEO is an Agile Development framework aimed to ease/speed the creation of web-based management applications by modeling real-world entities (and their behavior) as Object Models (XEOModels), which can then be used to generate web pages for listing, editing and searching instances of those object models.

XEO Concepts

Explanation of XEO Platform's Basic Concepts ( read more)

Architecture

Description of the internal architecture used by XEO ( read more)

An example application - XEO Library

In this chapter we describe our very first application, to show XEO's capabilities resolving real-world issues, by describing a management application for a library ( read more).

XEO Studio Introduction

In this chapter you'll learn how to create a new XEO Project using the XEO Studio plugin, and also to deploy a XEO Project ( read more).

Object Modeling - XEO Library

In this chapter we'll model the entities described in the sample application chapter, as XEO Object Models. This chapter will be divided in two parts. The first part consists of modeling a simple entity (Author) and showing how to quickly set up viewers for that Object Model and the second part where the remaining entities will be transformed to Object Models. Links to both sections bellow.

Modeling the Author entity ((read more))

Modeling the remaining entities ((read more))

Object Behavior - XEO Library

Controlling the desired behavior in each Object Model, using Java or BOL ( read more)

XEO Web Components - XEO Library

XEO's visual layer, to create web pages capable of interacting with the objects, check out the introduction to XEO Viewers and Web Components( read more)

Try the first viewer, the Author list, edit and lookup viewer ( read more)

Check the creation of a more complex viewer, the edit for the LIB_Book Object Model ( read more)

Get a feel of the Java API for Web Components ( read more)

Creating a more complex viewer, featuring custom lookup viewers and custom beans for the Movement edit viewer ( read more)

XEO Library Security / OPL (Object Policy Labeling)

Declaring security features of the XEO Objects in the Library Application ( read more)

XEO Modules

XEO can be extended with external modules. There are already two.

XEO Web Services

Provides access to XEO's Objects via REST / SOAP WebServices ( read more)

XEO BPM

Integrates XEO with a process engine (jBPM)

A XEO application's web.xml file contains some xeo-specific configurations which can customized ( read more).

Deploying a XEO Application to a J2EE Server (EAR)

The final step in creating a XEO Application is to deploy it to an Application Server (such as JBoss), in this section you'll learn how to create an EAR (using XEO Studio) and deploy that EAR to a JBoss server and the steps necessary to configure it correctly ( read more).
