ArcBees is a company founded by Christian Goudreau and Philippe Beaudoin that develops two open source projects: GWT Platform (GWTP) and Jukito. GWTP is a framework that uses the Model-View-Presenter pattern to build complex browser-based applications in Java that get compiled to JavaScript. It allows for loosely coupled and testable code and includes features like MVP lifecycle functions, activities and places for navigation, and support for advanced topics like security and client-server communications. GWTP and GWT are best suited for structured enterprise web applications rather than small sites or functional programming projects.
