At a glance the reuse of
a service and entitlement
to those service results
have nothing in common.
But on the second
thought, the more a
service gets reused the
greater the chance of
serving users with
different access rights
to the service results.
We'll discuss...
The main drivers for
SOA-based architectures
are to facilitate the
manageable growth of
large-scale enterprise
systems, to facilitate
Internet-scale
provisioning and the use
of services, and to
reduce the cost of organi
zation-to-organization
cooperation - SOA RM
SOA RM: '...in SOA,
services are the
mechanism by which needs
and capabilities are
brought together'
Recently OASIS voted the
SOA Reference Model (SOA
RM) into a standard. In
spite of its high level
of abstraction, this
model emphasizes the
business orientation of
SOA. 
In this article I'll
share my experience in
using the new features in
Java 5 for solving an old
industry problem, the
problem of collecting
constantly published
financial data in
reliable way. The
business case example I'm
going to discuss relates
to the acquisiti...
(Found in a blog,
'Versioning is as
inevitable as security.')
SOA development practice
isn't much different from
other software
development practices
except for design and
maintenance. Multiple
self-containing and
aggregated services that
interact with others have...
What could be easier than
to take your application,
wrap it with a Web
Service, announce it or
register it in the UDDI
and get a SOA Service?
Even better - take a data
warehouse, cover a SQL
executing code with a Web
Service and expose it to
SOA, isn't it simple?

This article describes a
workaround design that
allows a Portal to
survive if its resource
starts hanging request
threads. How frequently
does your Portal
experience user requests
hanging in the resource?
Not frequently, I hope.
However, if this happens
and the re...
This article describes
two techniques that may
be used for assured
delivery of important
data, specifically, audit
data, in distributed
systems. We will review
design that leads from
assured to guaranteed
delivery. This task gets
more and more important
in light o...
The requirements for
different user-facing
applications frequently
say something like: 'User
has to see/read/be shown
only funds/records/itiner
aries/policies he or she
is entitled to.'
Permissions in these
cases usually depend on
multiple factors related
to the us...
Application architects
have heard about the
increased importance of
security, but in many
cases they really don't
know how to approach this
issue. In this article,
I'll share my experience
and define a few basic
steps and checkpoints for
building application
