===================================================================
--------------------------------------------------------------------------
JAKARTA COMMONS - ALTERNATE (TO) REMOTE METHOD INVOCATION - "ARMI"
--------------------------------------------------------------------------
Abstract:
The ARMI package provides an alternative to Java's RMI. Apart from simply
being an alternative it provides the following features:
1) Any interface publishing
- no forcing of extension of java.rmi.Remote
- no forced declarations of "throws RemoteException"
2) Multiple transports
- Plain Sockets / ObjectStream
- via RMI
- Piped with same VM / ObjectStream
- Direct within same VM
- SOAP (planned)
- CORBA (planned)
- Plain sockets / custom messaging (planned)
- JMS (planned)
3) Speed
- Using the ARMI over RMI transport as a baseline. Measuring 100,000
method invocations after discarding the first for the purposes of
timing, ObjStream over sockets is three times faster, ObjStream over
Pipe is eleven times faster, Direct is a thousand times faster. Granted
there could be less of an advantage if compared to a proper RMI solution
(not layered), or one that is in the same VM with different threads.
4) Interface/Impl separated design.
- ARMI can be build easily into any application or application framework.
Individual aspects can be reimplemented (overridden) as the need arises.
Limitations:
1) Pass by value only.
- Unlike proper RMI, ARMI only currently supports "pass by value". If
an argument or return type were another ARMI published service, then
it could not currently be handled by ARMI. (to fix).
2) Generated "stubs" have to be in the client VM.
- Later we will allow server to pass forward implementation class
definitions as opposed to just newInstance() them as at present.

o Building
To build, you must have ant installed. Just type 'ant' -- the default
target will compile the classes (no jars at present)
o Demonstration of transport (see test package)
To test ObjectStream over Socket transport:
In DOS shell #1 - "ant -buildfile test.xml test1-serve"
In DOS shell #2 - "ant -buildfile test.xml test1-client"
To test ObjectStream Piped transport
In DOS shell #1 - "ant -buildfile test.xml test2"
To test (Armi over) RMI transport:
In DOS shell #1 - "ant -buildfile test.xml test3-serve"
In DOS shell #2 - "ant -buildfile test.xml test3-client"
To test Direct transport
In DOS shell #1 - "ant -buildfile test.xml test4"
o Use in your application
