The Net4j Signalling platform is an extensible client/server communications framework.
Net4j eases the development of fast and maintainable application protocols that are independent
of the physical transport medium. Transport protocols are pluggable and Net4j ships with support
for TCP, HTTP and in-memory transport. The core of Net4j is a fast, asynchronous and non-blocking
buffer multiplexing kernel, based on OSGi but also executable stand-alone.

The Net4j project is now integrated into the CDO project.
Downloads and other resources are provided there.

Core Features

Extensible signalling framework for application protocols (IProtocol, SignalProtocol)
Extensible transport framework for physical transports (IConnector, IAcceptor)
Multiplexing of different application protocols (IChannel)
Fast, asynchronous and non-blocking buffering kernel (IBuffer)

Transports

NIO-based TCP transport implementation (ITCPConnector, ITCPAcceptor)
In-process JVM transport implementation (IJVMConnector, IJVMAcceptor)
Polling HTTP transport implementation (IHTTPConnector, IHTTPAcceptor)

Examples

Extensible collaborations platform with buddy list, chat, fileshare, and more. Tutorial
JMS(TM) provider implementation (experimental but functional)

Utilities

Caching and monitoring framework
Special collections
Concurrency support
Wiring framework (managed containers)
Event framework
Factory framework
Generic finite state machine (FSM)
I/O tools
Lifecycle framework
Operations and maintenance framework (OM)
- Platform abstraction (OSGi, Eclipse runtime, stand alone)
- Bundle abstraction
- Logging abstraction
- Tracing abstraction
- Preferences abstraction
- Progress monitoring framework
Memory sensitivity framework
Transactional and notifying registries
Extensible security framework
Generic transactional operations framework
Debugging Tools
- Remote tracing (OM extension + Eclipse UI)
- Container view (Eclipse UI)
- Introspector view (Eclipse UI)
Extensible DB abstraction framework
- Derby DB adapter implementation
- HSQLDB adapter implementation
- MySQL adapter implementation
- PostgreSQL adapter implementation

-Net4j is an extensible client-server communications platform based on OSGi but also executable stand alone. You can easily extend the protocol stack with Eclipse plugins that provide new transport or application protocols. Net4j's focus on performance and scalability is featured by non-blocking I/O, zero-copy signals and multiplexed binary protocols. Net4j was originally developed to support the [[CDO]] technology for distributed shared and persistent EMF models but can also multiplex your own user-supplied application protocols through the same socket connection.
