Software Developer's Guide

This guide explains to Software Developers and System Administrators how to configure and customise iDempiere. Solid technical experience is required.

Status: This is Work in Progress, but it may be useful as it is.

Introduction

The core iDempiere system supplies a range business functionality straight out of the box, such as role-based access, organisational structure, accounting, procurement, warehousing, and so on, but it is also flexible enough to be adapted to meet new requirements as they arise, using these mechanisms:

• Configuration: changing the system using built-in facilities such as modifying field labels, setting parameters, modifying workflows, and using report-writers;
• Localization: adapting the system for a specific country, region or language by adding locale-specific components and translating the terminology;
• Integration: linking disparate software applications and platforms using predefined interfaces so that the subsystems function together as one system to support the enterprise objectives;
• Extension: creating new functionality by adding database attributes and plugins which do not affect the core system;
• Modification: you have access to the source code so you can turn your system into a tar pit, or big ball of mud, so don't modify the code or database schema by hand unless you intend to push the code into the trunk.

This guide explains how iDempiere can be adapted to meet new business requirements, without changing the codebase.

Configuration

Theme

• BusinessTeam Theme

WorkFlow

• Workflows

Report Writer

• Creating reports using JasperReports
• Plugin: JasperReports: sample set of Customer and Supplier Financial Statements

Localization

• Localization using language packs
• Example of German localization by changing country settings and installing a language pack
• Multilingual reports in Jasper

Integration

• Introduction to Web Services
• Describes the Web Service interface and its methods
• Web Services improvements to support composite services
• Web Services Security

Extension

Deploying externally developed plug-ins

The iDempiere community has developed a large collection of plug-ins and and made them available for download and deployment. These can deployed directly into the running application using the Apache Felix interface. The Eclipse development environment is not needed.

• Category: Available Plugins: list of Plugins from the wiki
• Set of plug-ins from Red1: useful set of plug-ins from one of the founder members of iDempiere

Development environment for customised plug-ins

You will need to set up the Eclipse development environment in order to develop plug-ins, as follows:

• Prerequisites for the development environment
• Download the iDempiere source code: includes some Download Tips here if you have a slow line
• Set up Eclipse: there is a more detailed guide with videos here
• Install the seed database
• Running iDempiere within Eclipse

Developing custom plug-ins

Once the development environment has been set up, you can follow these guides to develop various types of plug-ins:

• How to create a plug-in: a basic overview of creating a plug-in
• Develop a plug-in to change the look-and-feel: includes a video
• Develop a plug-in for a new process: includes process parameters, logs, and error handling
• Dashboard Panel Fragments: display relevant information and quick access to important functions for users from the main page
• Create a new class model with window and tabs: requires an understanding of database schemas
• Create a custom document class: documents are useful because they have a status and can be controlled in a workflow
• Hackers Guide to Documents: more about documents
• Group plug-ins and fragments into a feature: for deploying pieces of custom functionality in a single group

Deploying plug-ins

• Load your new plug-in into a running instance of iDempiere: including deployment using Apache Felix
• Here is an explanation about OSGi plug-ins

Build a customised instance of iDempiere

• Creating Installers from Eclipse: build your own custom installer using the Eclipse IDE
• Building iDempiere without Eclipse: build iDempiere directly from the command line, useful for continuous integration

Install and run iDempiere

• Installing from Installers: installing iDempiere from a zipped installer
• Running iDempiere from Installers: running iDempiere after installation and configuration
• Post Installation: some security meaures

Structure of iDempiere

• Equinox OSGi framework: describes OSGi and the technology stack that was used to build iDempiere so you can see how the system hangs together
• Eclipse Buckminster Component Assembly: looks at the use of Buckminster in the iDempiere project so that you can get a better understanding of the build process, and how Buckminster manages the components
