Jt Design Pattern Framework (overview)
Jt is a Design Pattern Framework for the rapid implementation of Java and Android applications. Jt has been utilized in several large mission critical systems. Jt is not an application (or game) but a messaging framework designed to help you build Android and Java applications. Please don't download unless you are looking for an Android/Java framework. The framework addresses the following goals:
A) The design pattern framework implements and/or facilitates the implementation of well known design patterns like Gang of Four design patterns (GoF) and J2EE Design patterns. The framework itself is conceived and implemented, from the ground up, based on design patterns.The framework also facilitates and accelerates the implementation of applications based on design patterns.
B) The framework architecture is based on the messaging design pattern (MDP): framework components are able to interchange information and perform computations by sending, receiving and processing messages. A messaging API provides simplicity, strong encapsulation and loosecoupling; framework components can be interchangeably plugged into complex framework applications using a "lego/messaging" architecture. Framework messages can be processed synchronously or asynchronously. The framework takes full advantage of the power and simplicity of the messaging design pattern/API.
C) The framework lego/messaging architecture provides transparent access to remote components and services: remote framework objects are treated as local objects. Design patterns implemented by the framework (adapters, remote proxies and facades) make this possible by hiding thecomplexities associated with remote APIs.
D) The framework provides transparent integration with other technologies via framework adapters, proxies and the implementation of related design patterns. These technologies include BPEL, BPM, Data Access Object implementations (DAO), Model View Controller implementations (MVC), EJBs, JSP, AJAX, ESB, JMS, XML, REST and Web Services.
E) The framework is designed to be lightweight and fast (low overhead/small footprint). The main Jt functionality runs on smartphones under Android.
F) The framework messaging/lego architecture should improve and simplify design/development efforts. There is a tight correspondence between UML design diagrams and the frameworkmessaging based applications and components needed for the implementation. The framework provides wizards and automated capabilities for generating framework applications. Framework components can be easily added to BPEL/BPM process diagrams. In future versions of theframework, it should be possible for repetitive application modules to be generated directly from the UML design diagrams. This goal is still work in progress.
G) The framework messaging architecture facilitates testing and debugging efforts. The framework provides capabilities for testing components as independent units by sendingmessages to the component and verifying the expected reply messages.
