  ---------------------------------------------------------------------------
  - JAKARTA COMMONS  -  ALTERNATIVE (TO) REMOTE METHOD INVOCATION - "AltRMI"
  ---------------------------------------------------------------------------
   
  -Abstract:
  +AltRMI has moved to Avalon-Excalibur
   
  -The AltRMI package provides an alternative to Java's RMI.  Apart from simply 
  -being an alternative it provides the following features:
  +See 
   
  -1) Any interface publishing
  -
  -  - Any object via the interfaces it publishes, can be published remotely.
  -  - No transport lock-in :
  -    - No forcing of extension of java.rmi.Remote
  -    - No forced declarations of "throws java.rmi.RemoteException"
  -  
  -    * These two features are part of the reason why Graham Glass's 'Glue'
  -      product is so successful. His API goes several stages futher in that
  -      it pubishes APIs via SOAP so that any language in any location can
  -      use Glue published Java services.
  -  
  -2) Multiple transports
  -
  -  - Plain Sockets / ObjectStream
  -  - via RMI
  -  - Piped with same VM / ObjectStream
  -  - Direct within same VM
  -  - Plain sockets / custom message streaming  
  -  - JNDI Done.  
  -  - SOAP (planned)
  -      - Might require additional undynamic "toWSDL()" step.
  -  - CORBA (planned)
  -      - Might require additional undynamic "toIDL()" step.
  -  - JMS (planned)  
  -  - UDP (planned)
  -  
  -3) Speed  
  -
  -  - Counting the number of 'void testSpeed()' invocations in 10 seconds,
  -    we can guage the differences (my Athlon900 machine)
  -    
  -    Speed Test type                   Count Relative
  -    ------------------------------- ------- -------- 
  -    
  -    AltRMI types over TCP/IP
  -    ------------------------
  -    - For remote publication
  -    
  -    a) ObjectStream over sockets #2    2702     1.00
  -    b) Over RMI                        4359	1.61
  -    c) CustomStream over sockets       6069     2.25
  -    d) ObjectStream over sockets #1   10088     3.73
  -    
  -    AltRMI types in the same VM
  -    ---------------------------    
  -    - These are useful for complete classloader separation
  -      of interface & impl using different classloaders. Impl
  -      and 'remote' proxy do not need to see the same 
  -      interfaces etc..
  -    
  -    e) ObjectStream over Pipe #2      12095     4.48
  -    f) Direct Marshalled #3           20759     7.68
  -    g) ObjectStream over Pipe #1      61166    22.64
  -    h) Direct Unmarshalled #        2391498   885.08
  -    
  -    #1 Without calling reset() as workaround to the ObjectStream bug
  -    #2 With calling reset() as workaround to the ObjectStream bug
  -    #3 Completely separates classloaders of client and server. Requires 
  -       a thread for each though.
  -    #4 Good as DynamicProxy for separation. Does not separate classloaders
  -       of client and server.
  -    
  -    Non AltRMI types
  -    ----------------
  -    - In VM, without using AltRMI - for comparison.
  -    - The inteface, impl and proxy cannot be separated in terms of
  -      branches of classloader for these three. The same interfaces 
  -      etc must be visible to both impl and proxy.
  -    
  -    i) DyanmicProxy #5
  -       (copied from Excalibur)     20282070  7506.32
  -    j) Hand-coded proxy #5         41214422 15253.30
  -    k) No Proxy #5                 42384804 15686.46
  -    
  -    #4 - For all of these three, the actual timing may slow down the test.
  -    
  -4) Interface/Impl separated design.
  -
  -  - AltRMI can be build easily into any application or application framework.  
  -    Individual aspects can be reimplemented (or overridden) as the need 
  -    arises.
  -
  -5) Choice of location of generated Proxy class.
  -
  -  - Classes providing client side implementation of the transported 
  -    interface(s) can be either on the client side or the server side (and 
  -    duly transported) at time of lookup.  On the server side, the proxy classes
  -    cal be generated in advance (Ant Task) or at runtime - javac is invoked.
  -    
  -6) Choice of castability of generated proxy class.
  -
  -  - To suit remote facilities that are happy with refection and do 
  -    not need to cast to an interface to use a bean (I am thinking of 
  -    BeanShell) the proxy class can be generated without specifying
  -    that it implements the interface(s).
  -
  -7) Suspendable/Resumable service.
  -
  -  - The Server supports suspend() and resume().  With the current impl this 
  -    replies in a timely fashion to the client that the client should try
  -    later.  The client waits for the notified amount of time and seamlessly
  -    trys the requets again.  A server could cycle through suspended and back
  -    to resumed will not affect the client except for the a delay.
  -
  -8) Recovering transport
  -
  -  - AltRMI tries to recover its transports should they fail.  The recovery 
  -    is pluggable in that the developer can choose when/how/if the connection
  -    handler tries to recover the connection.  Any inprogress, but
  -    disconnected method invocation will attempt to be recoved and just return
  -    as normal, albeit after a longer than normal delay.
  -  
  -9) Event API
  -
  -  - For suspensions, abnormal ends of connection etc, there is a listener 
  -    that can be set that will allow actions to be taken.  Abnormally 
  -    terminated connections will by default try to be reconnected, the 
  -    listener can decide if, how many, and how often the retries occur.
  -
  -10) Pluggable Transport indenpendant keep-alive concept.
  -
  -  - On the client side, there is an API for a pluggable pinger.  While the server
  -    may support timeouts for client connections, the client could choose to
  -    overcome that default policy with a ping concept.
  -  
  -11) Unpublishable and republishable API
  -  
  -  - The server is able to unpublish a service.  In conjuction with 
  -    suspend()/resume() a service can be republished, upgraded etc
  -    whilst in use, or just offlined.
  -
  -12) Startable API for Server
  -
  -  - The server implements and acts upon start() and stop() methods.
  -
  -13) Not just pass by value.
  -
  -  - AltRMI started life as 'pass by value' only.  In now supports return 
  -    types and parameters wrapped in another AltRMI Facade.
  -    
  -14) No duplicate instances.
  -
  -  - For Facades, if you call Person p = getPerson("Fred") twice you will get 
  -    the same instance on the client side is it is the same instance on the 
  -    server side.        
  -    
  -15) Load balancing server grouping
  -
  -  - In some configurations, the client side can have multiple servers it 
  -    will forward calls to.
  -
  -Limitations:
  - 
  -1) Use in EJB 
  -
  -  - This is not of any use for EJB Home/Remote interfaces.  The container 
  -    maker chooses the transport for use that container, not the bean coder.
  -    This is intended for other client server solutions.  Beside RMI over IIOP
  -    is Sun specified.
  -
  -Todo:
  -
  -1) Other transports
  -  
  -  - SOAP, CORBA (with WDSL & IDL generation steps)
  -  - Other RMI (over IIOP, over HTTP)
  -  - JMS
  -
  -2) BCEL (or other) for generated proxy class
  -
  -  - The current impl writes java source then compiles it.  We could do this
  -    inline with BCEL.  This as an heavier, but more design perfect 
  -    alternative to the current server side impl.
  -    
  -  - BCEL is really difficult to use if you are not skilled in it!!
  -
  -     
  -3) Client and Server code for secure conversations.
