Why a reference to the 'Aerospace Industry'?
that is the domain in which the founders of this architecture come
from. We believe that the problem this project solves is far more widespread
than just this industry.
Why another architecture, aren't there enough frameworks?
far too many. This is how we started. We looked at all the open source
projects at the time and started piecing together a solution based
on the ones that looked most promising. In the year we spent researching
and building prototypes we focused our efforts arround the following projects
JAFFA does on top of this is add Code Generators, Patterns, Processes,
Standards and Conventions that allow Domain Object Model's to be brought
to life with application business logic, wrapped in a transactional
component based packages, which integrates via a middleware layer
to the presentation layer. The presentation layer had been developed
such that it can support the most sophisticated web portal type requirements,
as well as providing a 'widget based' user interface for clean JSP's
and rapid development for complex presentations.
doesn't stop there; on top of this architecture there is a strong
focus on productivity tools. This is critical to the success of building
business applications. Applying J2EE architecture patterns is one
step, but the next is building complete usable components, and then
moving on to build groups of components to form the basis of a Business
vision of being able to model your business domain, turn it into real
working persistent objects, and then rapidly build usable components
on those object, would cut out a huge amount of time in the initial
project stages. Then the real work would be solely focused on implementing
the domain specific business logic and custom presentation aspects
of the solution.
Why open source?
that build software solutions need architecture, they often buy it
and then live with its constraints, and the constraints of the Vendor
providing it. What business really want is a standards based, open
framework, supported by a community of developers with similar business
needs, that give them a zero risk, zero cost solution of adopting
it. No development or run-time licensing fees, no limits on what they
can and can't use it for, no limits on how they can adapt any part
of the framework to suit their differing business needs.
want to be buying into a framework that through its openness is supported
by a community of developers with likeminded interests, which will
be constantly supporting, testing, reviewing, extending, fixing this
framework so it meets the needs of the business applications it must
Why the focus on Business Applications?
Applications tend to have a very strong emphasis on complex domain
object models, data intensive transactions, and requirements for robust
B2B interfaces. This is what the J2EE platform is design for, but
the details of distributed transaction processing and management of
persistent objects puts a huge burden on the development of these
solutions. JAFFA attempts to make this simple, but without compromise.
