<<Inside the LAN, there are many other alternatives to web services
which may improve our service-oriented environments. They can do this
by increasing network performance through creation of smaller data
sets to transfer, decreasing computational power needed to unmarshall
the data sets, and mobile code in their support of mobile agents and
smart proxies. There are many technology platforms which pose a viable
alternative to web services on the LAN and meet some or all of the
improvements mentioned. One of those technology platforms is Jini.

Jini by itself does not solve the problem but containers built on top
of the Jini platform do. Containers remove some of the Jini
programming complexity by handling codebase downloading and service
deployment. Here are a few example containers:

     * Rio - A dynamic services platform which involves a federation of
container nodes onto which services are deployed. Upon deployment of a
service, the platform identifies nodes which meet the service level
agreement (SLA) declared in the Rio deployment descriptor called an
operational string.

     * Harvester - A container environment for Jini services and
clients. A particularly interesting feature of Harvester is it's
ability to load services and clients written in the Python language.

     * Neon - An agent framework and application grid fabric which
allows your Jini services to be deployed without writing all of the
associated plumbing code. An good introduction to Neon's capabilities
may be found here.

Mobile code is an important reason why Jini is a good alternative to
web services on the LAN. Many Java developers are aware of RMI (remote
method invocation) but have not heard of the Jini RMI impelementation
called JERI (Jini extensible remote invocation). JERI provides
important features over it`s older counterpart: a pluggable transport
layer with security support, an extensible marshalling layer, and
runtime configuration. JERI provides the ability to export your
service proxy for use by a remote service consumer. Your proxy class
may be a "smart" proxy which means that some, if not all, invocation
processing is performed using the consumer`s resources.>>

Me too. It seems to point to a universal OS, one that is very robust and
inherently network-centric. Ie it's only role is to make the device work
and connect to the network, where it can then access apps/data.

The other day I was trying to get a CD based game working for my kid, and
oh boy what a hassle. Wrestling my way through Windows on an older PC was
so slow and so painful, when all I really need is a "KidStation". Ie a
fairly dumb device that can run multimedia programs. A PC is really
overkill for this and even many corporate situations, so it may be that
the red herring in the mix is the PC/Windows component, which is now quite
out of date and a constant source of pain around which everything
revolves. So perhaps it's time to think in terms of a new model for
this....

Very!

A registry is little more than a service which offers information
about services, as well as pointers to related services.

The Web already houses many registries, for example;

http://www.iana.org/assignments/media-types/

(as well as many other at iana.org)

Granted, the information returned from that one is (currently) HTML,
but it could easily return an XML document.

UDDI's (3.0?) addition of HTTP GET support (which returned XML, not
HTML) put UDDI information - previously only available to UDDI clients
- on the Web, available to anybody with an HTTP client.

As I have mentioned before, Gregg Wonderly (please excuse my previous
misspelling of your surname, Gregg) is a great apostle of J/JS.  I
must confess, I do not keep up with the latest changes in the Jini and
JavaSpaces specs., and for those of you in a similar position it is
worth looking at Gregg's latest posting to my SOA Group:





http://groups.yahoo.com/group/service-orientated-architecture/message/3274

Gregg has certainly convinced me, ignorant non-techy that I am, that
the moment is propitious for the world to reconsider J/JS in the
context of curent developments in distributed computing in the form of
SOA/BPM etc.

So, for sake of a newbie, although called Javascript, it's quite a
fundamentally different technology (vs Java)?

I get the idea that as a scripting language, it's going to be quite
lightweight? If so, then Jini/JS could be suggested as being a heavyweight
version of the same kinda thing?

Cool.

And the business application of this is again the same kind of thing?
Creating small application components that are more 'local' in nature, so
this could be for intranet employees or online customers?

Thanks, regards,

Neil.

Mark,

Let us go back to an example I suggested earlier: the building of a
SOA registry/repository using JavaSpaces.  How suitable would your
paradigm be for this?

It would be a good learning exercise, but practically, I think that
HTTP already provides most of what is useful from tuple spaces, as
well as some improvements on the model; large data object support
(chunked transfer coding), safe retrievals (GET), idempotent mutation
(PUT), application model (hypermedia).

What it's "missing" is a tuple matching & notification mechanism, but
that stuff is basically being done as extensions.  For example, I
would expect that SPARQL + mod-pubsub would give you most/all of those
capabilities, and probably more.

Mark.

Mark,

Do you think it would be a useful open source project to create a
tuple spaces product with a language-neutral network protocol?

It is revealing the kind of power that mobile code provides.  It's lack of
security and some other features that Jini and ServiceUI provide make for a
prime opportunity for Java mobile code to flow back into view.

I continue to work on a refine a ServiceUI desktop interface that provides the
ability to utilize multiple ServiceUI's simultaneously in a "come as you are"

Nope, it was one of the sub-frameworks of the Objectspace Voyager
product (Graham Glass' old company).  In fact, I just tracked it down.
  It's called simply, "Spaces";

I'd like to think that the spirit of the tuple space model lives on in the Web.

The big problem with tuple spaces isn't the architectural style though
(mostly) IMO, it's that in practice, as determined by several
independent tuple space implementations, interoperability is defined
in terms of software libraries rather than network interfaces.  If,
say, JavaSpaces had defined a "Spaces" network protocol and then
implemented Java based client and server libraries that implemented
that protocol, then you could connect, say, a Perl implementation of a
tuple space with a Java implementation of one.

Of course, HTTP is, give or take, such a protocol, and folks have been
connecting software components (browsers, servers, spiders, command
line tools like curl/wget) written in different languages in just this
way for many years on the Web.  It's funny how the world's largest and
most successful distributed system can be taken for granted by so many
people, no?

Interesting, Mark - and there I was thinking you lived, breathed and
slept REST!  Could your tuple space product have been TSpaces from IBM
or Linda?

BTW, I wonder if anyone has used J/JS for a SOA registry/repository.
I believe JavaSpaces has been used to build up a Jini LUS, so why not
a SOA registry?

I suspect that the way SOA is taking distributed computing a
significant architectural step forward will open up a lot of potential
applications for J/JS.  In the brave new BPM/Composite Apps/SOA world
where agility, robustness and scalability become increasingly
important, J/JS might yet find the moment has arrived...

Well I think it quickly comes back to the recurring theme for Jini
conversations, as one point. Ie it's not always the best technology that
becomes universally popular. Windows is not the best desktop client,
but.... etc.

Ajax is achieving the same, ie it's also tackling i) easy adoption for
larger markets of developers, and ii) "branding", ie it has a 'cool' image
etc. The two go together very well.

I guess the point for discussion I was making is that while it may not be
the best iteration of it, it's demonstrating principles that perhaps Jini
can use as a context for pushing itself higher into a larger
consciousness. Eg what's good about Ajax? Perhaps its the localising of
computing closer to the user? Perhaps it's xyz. If so, can the same end
result be achieved better? If so, how?

Thus a 'compare and contrast' could be a great way to position Jini.

Best regards, Neil.

Ajax is principally about (finally) the growing adoption of distributed
computing.
What do folks think about the potential relationship between Jini and
Ajax, if there is one? Is it creating a context for a more meaningful
debate about the value of Jini?

1. Built on sand - too much heavyweight code is developed using a programming language (Javascript) that was never designed to take the strain.
2. Badly architected - not only is AJAX a kludge on top of HTTP right from the start, but it tends to lead to poor design, breaking the Model 2 MVC practices that were finally becoming mainstream.  This is changing as better practices start to appear for AJAX, but there is no layering implicit in AJAX itself so there will always be the temptation to write poor code.
   
3. Server- and browser-dependent - you cannot run an AJAX application without connecting to the server in question using an appropriately capable browser.  What about apps that need to run offline and with more choice of device?

I haven't used JavaSpaces specifically, but I did put together a
prototype using the Objectspace Voyager product back in '97 (IIRC).
Voyager consisted of several frameworks supporting different styles of
distributed computing, and one of those was a tuple space based
framework very similar to JavaSpaces.  I forget the name of that
framework though.

It was very easy to use, and once built, very easy to add new spaces
into the mix... which is unsurprising given that all spaces exposed
the same interface, meaning clients could interact with every new
space that was created without requiring upgrades.

It was also instrumental in helping me to fully appreciate the scope
and power of the Web, as it shares many important similarities with
tuple space based systems.  The Semantic Web even more so, in fact.

In my SOA Group, Jini seems to earn frequent mention.  This is not
just due to the efforts of Gregg Wonderley who is a passionate,
articulate and knowledgeable advocate of Jini - he certainly deserves
a massive reward from Sun.  I suspect that J/JS's robust, decoupled
nature makes it an ideal connectivity tool for building a SOA
structure.  Do any of you have practical experience of this?  I know
that IntaMission, for whom I did some consultancy in the past, have
used JavaSpaces in their software and are very much now targeted
towards SOA.  There must be others of you out there who have used J/JS
to knit together a SOA implementation.

If so let's hear about it!

<<Jini was originally released in 1999 as a way to link consumer
devices to Sun's Java software. But companies using the Jini
software have been using it mainly for corporate computing jobs such
as grid computing and clustered servers, according to Sun
executives.

The software is specifically designed for building Java applications
that rely on widely distributed components. For example, Sun uses
Jini as part of its radio frequency identification software, which
runs in small warehouse RFID readers.

The development of the Jini software is done through the Jini
Community, an independent forum in which companies other than Sun
contribute changes to the software.

At a Jini Community meeting in Chicago on Wednesday, Sun executives
are expected to announce that the Jini Technology Starter Kit
version 2.0 is available under the Apache License 2.0.

The adoption of the Apache license is part of Sun's plan to make the
Jini Community operate like an open-source foundation, Sun
executives said. A popular previous edition of the Jini Starter Kit,
version 1.2, will also be made available with the open-source

into the correct directory hierarchy.

Hi all,
Just a message to inform you that there will be a Jini/Rio talk during
the Javapolis conference http://www.javapolis.com
It will be a case study: the Magnetti Marelli Formula One Telemetry
application
http://www.javapolis.com/confluence/display/JP05/F
ormula+One+Telemetry+with+
Java

Javapolis is the 2nd world largest conference dedicated to Java
technology.
We expect 2000 people this year. In the previous edition, there was no
Jini-related session, not even a Bof. I found this situation shameful,
so this year the steering committee managed to get a killer case study
with Jini in the conference.

I hope we can get even more space for Jini @ Javapolis next year. It
deserves it.

PS: there is space left in the agenda for Bofs and Quickies, anyone
interested?

This looks an interesting opportunity to present J/JS in a SOA
context.  Bear in mind when considering your physical comfort that it
will be Spring, not Autumn in Melbourne then...

Given Gregg Wonderly's sterling efforts to proselytise J/JS, I would
have thought that he would be an obvious contributor - worth paying
his airfare at least!

Hello,

We have conference coming up that is about creating an adaptive and
agile enterprise through effective management, governance and
understanding of Service-Oriented Architecture (SOA)

It will take place on 8-10 November 2005, in Melbourne

Visit www.ark-group.com for more information and find out more about
our early registration discounts, as last year's conference hit the
maximum capacity.

Thank You

Steven Oesterreich

Some of you belong to or are familiar with Frank Greco's NYJavaSIG.
This Group has been quite active in hosting Jini-orientated events.
An example is the forthcoming event described at:

CALL FOR PAPERS AND REFEREES
                     ============================
              (Apologies if you receive multiple copies)


           21st ACM Symposium on Applied Computing (SAC 2006)
              http://www.acm.org/conferences/sac/sac2006/

    Special Track on Coordination Models, Languages and Applications
                  http://confs.deis-ce.unibo.it/sac/sac2006
                        http://sac2006cm.cs.fit.edu/

                          April 23-27, 2006,
                            Dijon, France



SAC 2006
~~~~~~~~
For the  past twenty years,  the ACM Symposium on  Applied Computing
has been  a primary gathering  forum for applied  computer scientists,
computer  engineers, software  engineers,  and application  developers
from  around the  world.  SAC  2006 is  sponsored by  the  ACM Special
Interest  Group on  Applied Computing,  and  is hosted  by  Bourgogne
University, Dijon, France


Coordination Models, Languages and Applications Track
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Building on the success  of the seven previous editions (1998-2005), a
special track  on  coordination  models,  languages  and  applications
will be held at SAC 2006.  Over the last decade, we have witnessed the
emergence of models, formalisms and mechanisms  to describe concurrent
and  distributed  computations  and  systems  based  on the concept of
coordination.  The purpose of a coordination model  is  to enable  the
integration   of  a  number   of,  possibly  heterogeneous, components
(processes, objects, agents) in such a way that the resulting ensemble
can  execute as  a  whole,  forming a  software  system  with  desired
characteristics and functionalities which possibly takes  advantage of
parallel and distributed systems. The coordination paradigm is closely
related to other contemporary software engineering approaches  such as
component-based  systems  and middleware  platforms.  Furthermore, the
concept of  coordination exists in  many other  Computer Science areas
such  as   Cooperative  Information  Systems,  Distributed  Artificial
Intelligence, and Internet Technologies.

The Special Track  on  Coordination Models, Languages and Applications
deliberately takes  a broad view  of  what is coordination:  this term
covers here traditional models and languages  (e.g., the ones based on
the  Shared  Dataspace  and  CHAM  metaphors),  but also other related
notions  and  formalisms   such  as  configuration  and  architectural
description  frameworks, models of  multi-agent planning, organization
and  decision-making,  systems modeling  abstractions  and  languages,
programming skeletons, etc.

Correspondingly,  in addition to the traditional areas covering  data-
driven (such as Linda)  and control-driven  (such as Manifold)  models
and  languages,   this   Special   Track  aims   at  putting  together
contributions from all the many areas where the concept of coordination
is relevant,  such  as  multi-agent systems,  software  architectures,
middleware  platforms,   groupware  and   workflow  management,  etc.,
providing them  with a  forum where  they can discuss  their different
viewpoints and share ideas.   On  this  very  subject,  it is worth to
remind that the last editions of this Track were undoubtedly successful
under many points of view,  but  in particular in  attracting relevant
and consistent contributions from many different research communities.

According  to  that,  major topics  of  interest include  (but are not
limited to) the following:

    * Novel models, languages, programming and implementation techniques
    * Applications
    * Internet- and Web-based coordinated systems
    * Coordination of multi-agent systems, including mobile and
      intelligent agents
    * Languages for service description and composition
    * Models, frameworks and tools for Group Decision Making
    * All aspects related to Cooperative Information Systems
      (e.g. workflow management, CSCW)
    * Software architectures and software engineering techniques
    * Configuration and Architecture Description Languages
    * Middleware platforms (e.g. CORBA, Jini)
    * Coordination technologies, systems and infrastructures
    * Emergent Coordination and Self-organization.
    * Relationship with other computational models such as object
      oriented, declarative (functional, logic, constraint) programming
      or their extensions with coordination capabilities
    * Formal aspects (semantics, reasoning, verification)


Proceedings and Post-proceedings
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Papers accepted for the Special Track on Coordination Models, Languages
and  Applications  will be  published  by  ACM  both  in  the  SAC 2006
proceedings and in the Digital Library.

It is worth to notice that after the last editions of the Special Track
on Coordination, four special issues were published, namely

                "Coordination Models and Languages in AI"
                 Applied  Artificial Intelligence  15(1)
                http://lia.deis.unibo.it/journals/aai2001/

            "Coordination as a Paradigm for Systems Integration"
                   Journal of Systems Integration 10(2)
                http://lia.deis.unibo.it/journals/josi2001/

                 "Coordination and Knowledge Engineering"
                  The Knowledge Engineering Review 17(4)
                   http://uk.cambridge.org/journals/ker/

              "Coordination and Collaboration Technologies"
             Journal of Cooperative Information Systems 13(1)
               http://www.worldscinet.com/ijcis/ijcis.shtml
and
                           "Coordination Systems"
       Journal of Concurrency and Computation: Practice and Experience
           http://www3.interscience.wiley.com/cgi-bin/jhome/77004395

while a sixty one
                   "Role of Contexts for Coordination in MAS"
                  Web Intelligence and Agent Systems Journal
                    http://www.iospress.nl/html/15701263.php


is currently under preparation.

So,  among the papers accepted and presented  this year at the SAC 2006
Special Track  on  Coordination,  a further selection  is likely  to be
performed  after  the symposium  to  produce  a  special issue  of some
international journal: several contacts are currently ongoing.
