MINA is a simple yet full-featured network application framework which provides:
* Unified API for various transport types:
o TCP/IP & UDP/IP via Java NIO
o Serial communication (RS232) via RXTX
o In-VM pipe communication
o You can implement your own!
* Filter interface as an extension point; similar to Servlet filters
* Low-level and high-level API:
o Low-level: uses ByteBuffers
o High-level: uses user-defined message objects and codecs
* Highly customizable thread model:
o Single thread
o One thread pool
o More than one thread pools (i.e. SEDA)
* Out-of-the-box SSL · TLS · StartTLS support using Java 5 SSLEngine
* Overload shielding & traffic throttling
* Unit testability using mock objects
* JMX managability
* Stream-based I/O support via StreamIoHandler
* Integration with well known containers such as PicoContainer and Spring
* Smooth migration from Netty, an ancestor of Apache MINA.
Apache MyFaces Orchestra aims to provide a simple way to combine a web-framework with a persistence layer. Typically, an Apache MyFaces Orchestra stack might combine JavaServer Faces, Spring and a JPA implementation like Toplink, Hibernate, etc.
The underlying idea is to provide long persistence sessions to the web-developer - this is done by associating these sessions with a conversational context.
The conversational context is opened when the bean configured for this context is first loaded. It can be manually closed by the programmer, plus a time-out can be configured as a global parameter.
