Message-centric vs
RPC-style Web services is
a long-standing debate
and bone of contention
regarding the proper use
of Web services
technologies. Early
renditions of SOAP and
XML-RPC were all about
providing RPC-style
interactions...
Replication is a process
of synchronizing data
among the participants
(or entities) in the
operator cloud. The cloud
acts as a single logical
entity or entry to the
outside world. The goal
of replication is to
facilitate uniformity ...
The Web services vision
of loosely coupled
interaction between
components, programs, and
applications is already
beginning to create
impressive efficiencies
of scale in business
integration. The notion
of a Web service registry

This article, the first
of two parts, will
compare and contrast Web
services with other
distributed computing
component technologies
such as CORBA, J2EE, and
DCOM. We look at these
approaches in the context
of their respective
ca...
RPC-style Web services
aim to expose a business
object as a Web service
interface described by
WSDL (Web Services
Description Language). On
the other hand,
document-based Web
services are based on the
exchange of XML documents

This article takes a look
at SOAP Message handlers
and how JAX-RPC supports
SOAP Message handlers and
its usage scenarios.
First, some of the
terminology: a SOAP
Interceptor takes raw
SOAP message as input
and, before processing
t...
Portlets are visual
components that make up a
Web page residing in a
Web portal. Typically,
when an end user requests
a personalized Web page,
multiple portlets are
invoked when that page is
created. An example is a
news/financial p...
On guard! What do Web
services have to do with
a swordsman? Well,
paraphrasing Alexandre
Dumas's character, 'if
you don't go to Web
services, Web services
will come to you.' Web
services are pervading
every layer of enterprise
com...
Integration efforts
within an enterprise have
been aided by the
adoption of
service-oriented
architectures and common
integration
infrastructure. While the
service-oriented
architecture needs to be
driven from within the

The notion of distributed
computing has been
evolving for a long time,
during which we have been
building business
solutions by integrating
various systems and
platforms. Typically,
these interactions are

Portals are central
points of access for
applications and content
for both internal and
external use in an
enterprise through
interactive and rich
presentation interfaces.
The growth of
applications using the
.NET platform has
generated an increased
emphasis on performance
measurement and analysis.
Distributed applications,
while much more flexible
and potentially more
scalable than monolithic
ones,...
Back in the old days,
when you needed to
communicate with someone
distant, you usually had
to send a letter. There
was no instant response,
and there was no way to
tell when your message
was received. Now we have
always-on e-mail,
