History

The history of JFire starts in 2003, when the company NightLabs decided to develop a new ticket

 (rather than multiple separate programs), they started to search for a suitable framework. After some research and evaluations, they decided to launch such an ERP framework project based on new technologies like JDO and Eclipse RCP, which make it easy for other projects to build upon.

When first released in January 2006, it quickly gained attention in the Eclipse community: The German Eclipse Magazine published an article in May 2006, the project was invited to the EclipseCon 2006, the Eclipse Magazine India published an article in December 2006 and in April 2007, the JFire project was invited to the Eclipse Forum Europe, where it impressed the BIRT team with its graphical parameter workflow builder.

Goal

The project's main goal is to provide a framework which eases development of sector-specific ERP systems. In this aspect, it differs significantly from most other ERP projects, which aim primarily at being an out-of-the-box solution directly for end-users.

The JFire project team believes that the demands directed at ERP software vary in such a high degree, that a complete solution has some major disadvantages: In their opinion, such one-fits-all-solutions confront their users either with too much configuration and too little clarity or do not provide enough flexibility.

Therefore, most of the numerous JFire modules serve mainly as a base for extensions and cannot be used directly by end users (or only partially).

Architecture

JFire consists of two parts - the server and different types of clients. So far, the most comprehensive client is a rich client. Additionally, there exists a JSP

 web client, which currently supports only a part of the functionality (e.g. a web shop). Some applications built on JFire employ other types of clients, as well (e.g. mobile devices

 used in Yak, an access control system). Because JFire enables different companies/organizations to cooperate directly, a server acts as client to other servers, as well. Each organization has its own JDO datastore, which guarantees a very high degree of protection of privacy. Between organizations, only data essentially required by the business partner are exchanged.

Following the framework idea, JFire is built very modular: In the client, it consists of OSGi

plug-ins based on the Eclipse Rich Client Platform (RCP) and in the server, JFire is composed of Java EE EAR modules. Due to its modularity, JFire is used as base for non-ERP applications, too, which employ a smaller number of modules (e.g. only the user, access rights and organization management).

Server

The Base-Module is responsible for Authentication, User- and Rightsmanagement and builds the core for transactions between different organisations and servers. On top of it comes the Trade-Module which includes Accounting, Store-Management, Reporting and forms the base for a general distribution sales network.

The Trade-Module offers many interfaces for easy integration of external systems like third-party payment- or delivery-systems. Additionally it provides extension possibilities to build your own Business Application on top of JFire.

Client

The Client is based on the Eclipse RCP framework and makes extensively use of its flexible plugin management. The design is similar to the server. The Base module provides you with the Graphical User Interface for administration of users and organisations. The Trade modul lets you easily configure the sales-conditions of your products, write invoices, keep the overview over your finances and show you detailed reports of all transactions.

Furthermore you can combine your Trade platform with the Editor2D module in order to edit and visualize things, if it is needed for your business.
