The cajo project is a small,
100% Free library, enabling powerful dynamic multi-machine
coöperation; both within and between, both free and proprietary Java
applications. It is a surprisingly easy to use, yet completely
understandable framework, unmatched in performance. It is actively being
deployed in Java EE, SE, and ME environments all over the world. It is a
uniquely 'drop-in' distributed computing framework: meaning it
imposes no structural requirements on your applications, nor source
changes. It allows multiple remote JVMs to work together seamlessly,
as one. Welcome to our foundation for the
World Wide Virtual Machine. (WWVM)
Project goals
- Establish a free, simple, distributed paradigm; which becomes increasingly
valuable with greater adoption.
- Encourage increased distributed inter-operation; between developers,
applications, and component libraries.
Major features
1. The framework allows any number of Java Virtual Machines to work together
literally as one. Applications can evolve dynamically: from all objects
being in a single Virtual Machine, to all objects being in separate Virtual
Machines, to all objects being in separate physical Machines, even at
runtime. All without source impact, it works with simple
POJOs.
2. Easily create completely safe unsigned rich internet applications (Java
RIA) both as Applets and via WebStart, which operate indistinguishably from
locally installed applications. Transfer an application's entire user
interface to any Java equipped client, automatically. Cleanly separate the
components of the model view and the controller portions of an application,
between multiple machines.
3. The framework allows both applications, and developers, to collaborate
dynamically. This architecture can literally turn the network into one
seamless evolving computer; linking everything from mainframes to mobile
phones. It can allow applications to be built using optimised components
from other distributed applications. Remoting and linking of any object
can be done with as little as one additional line of code. Objects
can be remoted: Even if their source are not available.
The framework has no dependencies on any 3rd
party libraries. It works with all Java Runtime Environments 1.2 and higher.
Coöperating Virtual Machines can be behind NAT, firewalls, even HTTP
proxies. No special tools or IDE plugins are needed, it can even be used from
the humble command prompt. If you are using another distributed computing
framework; it is very simple to add support for cajo, and further increase
interoperability.
Best of all, this framework is 100% pure Java™: i.e. it uses
no bloody <XML>!
Nor "
pixie dust"
@nnotations: It's not a POJO, if it needs annotations.
The core framework consists of just three, very small, and well documented
packages:
- gnu.cajo
(4 classes) provides a high-level functional interface
- gnu.cajo.invoke
(6 classes) defines the architectural core for clients
- gnu.cajo.utils
(8 classes) extends this core for the creation of servers
