Technology

Joget Workflow incorporates a multitude of open source and open standard technologies:

Open Platforms

Java

• Vendor neutral, platform independent implementation that will work on Windows, Linux and various flavours of Unix

MySQL

• Primary database, database independence using Hibernate framework

Apache Tomcat

• Using Apache Tomcat as the primary web application server for distribution

GlassFish

• Using Sun GlassFish application server as the development build and test server
  
  

Frameworks and Libraries

Spring Framework

• One of the most popular and powerful Java development frameworks

• Using the core framework features such as Dependency Injection (DI) and Aspect Oriented Programming (AOP) plus modules like Spring MVC, Spring Security, etc

Hibernate

• One of the most popular Java persistence frameworks, using ORM (Object-Relational Mapping) for stability and database independence

Apache Felix

• Open source implementation of OSGI, a dynamic module system for Java; used to implement plug-in architecture for true plug-and-play support

Enhydra Shark

• Embeds the Enhydra Shark workflow engine that supports XPDL 1.0

JPEd

• Open source workflow editor based on Enhydra JaWE , supports XPDL 1.0

JQuery

• Popular lightweight JavaScript library for presenting a dynamic user interface

Development Tools

Joget Workflow is being developed using the following development tools:

Maven

• Popular tool for Java project management and build automation

• Project Object Model (POM) defines project, dependencies, etc

• Similar to Ant, but different; embraces “Convention over configuration”

Archiva

• Maven repository management software

• Used as a local proxy

Redmine

• Project management and bug/issue tracking system

• Integrated to Subversion, wiki, issue tracking - all-in-one

• Recent switch from Trac to Redmine to from Trac previously

Sonar

• Open source quality management platform, dedicated to continuously analyze and measure source code quality

Development Methodology

Continuous Integration

Continuous integration (CI) is a software development process that rebuilds, integrates and tests applications frequently. CI is used to reduce risks and repetitive manual processes to improve quality.

Some of the CI practices being used:

• Single Source Repository : Source code management system – Subversion

• Automated Builds : Using open source Hudson continuous integration server

• Automated Testing : Using the JUnit testing framework

• Frequent Commitment : Commit smaller chunks and changesets frequently

• Fast Builds : Full build in 5-10mins

• Automated Releases : Maven Ant Plugin, NSIS Windows Installer System. Linux packages (.deb, .rpm) in future
