Bridge API to connect with existing Java APIs.

Deft is a single threaded, asynchronous, event driven high performance web server running on the JVM.

The goal of Simple is to bring the power of simplicity to the world of server side Java. The primary focus of the project is to provide a truly embeddable Java based HTTP engine capable of handling enormous loads. Simple provides a truly asynchronous service model, request completion is driven using an internal, transparent, monitoring system. This allows Simple to vastly outperform most popular Java based servers in a multi-tier environment, as it requires only a very limited number of threads to handle very high quantities of concurrent clients. Simple has consistently out performed both commercial and open source Java Servlet engines and has a fully comprehensive API that is as usable for experienced Java developers as it is for beginners. Best of all, Simple is completely free, and is released under the terms of the Apache License, which ensures its availability for use by open source and proprietary developers alike.

With Roo's Cloud Foundry integration you can now manage the entire life cycle of your application from the shell. Aside from stopping and starting you can: scale it, by changing the number of instances running and the allocated memory; view deployed applications and provisioned services and how they interrelate, map and unmap URLs, view detailed stats on the application, and bind and unbind services. And with Roo's clever auto-completion technology managing your presence in the cloud has never been easier.

It provides the foundational building blocks for higher level text understanding applications.
