Transactions and Web Services
With the advent of Web Services, service
providers who wish to take advantage of this large B2B space are
populating the Web. However, there are still important security and
fault-tolerance considerations, which must be addressed. One of
these is the fact that the Web frequently suffers from failures that
can affect both the performance and consistency of applications run
over it. For example, if a user purchases a cookie granting access
to a newspaper site, it is important that the cookie is delivered
and stored if the user's account is debited; a failure could prevent
either from occurring, and leave the system in an indeterminate
state. Read the full story: http://www.hpmiddleware.com/newsletters/hpdevelopernews/feature/may02.html

Evolving Success Factors for Application
Servers
by Jon Maron, HP Middleware As more and
more features get rolled into these J2EE application servers,
spurred both by user demand and the competition of vendors busy
distinguishing themselves in the marketplace, a new architecture is
being pushed by several companies. These companies identify the need
for J2EE application servers and the solutions built on them to be
adaptable and flexible to new technologies. As the J2EE
specification grows, along with Web services, the need for a
services oriented approach to application servers and applications
is necessary to keep vendors and enterprise development groups
responsive and iterative in their deployment. Jonathan Maron is a
distinguished engineer with Hewlett-Packard's middleware division.
He was the lead on HP Bluestone's J2EE 1.2 compatibility effort, and
also principal architect of the Bluestone EJB 1.1 server. Jonathan
is a member of the JavaSoft EJB and J2EE expert groups. Read

Key Features of UDDI4J Version 2
Ravi Trivedi writes about the
new features in the UDDI4J API that will improve the programming and
capabilities of Web services. Ravi is a Technical Lead for
the UDDI4j and UDDI teams at Middleware Labs, E-Solutions Division,
Hewlett Packard, Bangalore. He holds a masters degree in computer
science from the Indian Institute of Science and is an expert group
member for HP in JAXR (JSR 93). He is a committer for the UDDI4j
project at www.uddi4j.org and has been involved in developing core
Web services infrastructure such as UDDI and e-speak. He has been
responsible for architecting and implementing some of the very first
solutions in production using Web services. Trivedi is also
presenting at Invent 2002, the HP worldwide developer conference,
May 28-31 in Las Vegas http://www.hp.com/go/invent2002.

Avoiding Pitfalls in Declarative Security: A
roadmap to portable access policy
Applications need to prevent improper
access to data and ensure that data integrity can be maintained. To
guard against such compromises, developers must first have an
awareness of resource sensitivity. Proper safeguards need to be in
place within the workplace and development process to ensure that
sensitive information isn't inadvertently made available for
improper viewing and/or modification. This article describes
certain aspects of J2EE declarative security, in particular how
security constraints are used within the Web tier to protect access
to resources with varying levels of sensitivity. It also illustrates
the use of a sample application as a tool for determining the
behavior of a given application server's constraint matching. I'll
also share some of the issues I encountered while developing and
deploying the sample application across several application server
platforms. Larry McCay, a
senior architect for Hewlett-Packard Middleware, has been designing
and developing software for over 10 years. Larry has been a major
contributor to the Hewlett-Packard Application Server and Netaction
Platform and is active within the JCP in the area of security.

Developing Real-World Web-Services-based
applications
by Sandeep Chatterjee, Ph.D.
published April 22, 2002 Web Services
are software components that are exposed to a network via a
statically-defined interface, allowing other applications to be
developed that leverage that exported functionality. Web Services
are interesting and differ from other distributed computing
technologies because they are based on SOAP messages, which are
encoded XML transported over HTTP (among other common protocols).
Essentially, Web Services provide a reasonably lightweight and
standard mechanism for computer-to-computer communications.
While many believe that "killer apps" will make Web Services
catch on, it is in fact a well thought out application architecture
that will foster innovation, support short time-to-market, and keep
a lid on operational overhead. Read the full article at www.javaboutique.com.
Extreme Java GUI Testing
Tom Hammell, TID
published: April 24, 2002 The ideas of
Extreme Programming (XP) has been considered by most developers as a
way to try to produce quality software in today's fasted paced
development environment. Although not everyone agrees with all
aspects of XP, the idea of unit testing is a widely accepted
practice. The basic idea is that tests are written as code is being
developed. This allows a developer to keep track of the state of the
software as it is being developed and also gives them the ability to
easily run regression tests as the code is refactored. With today's
short development cycles, developing software without unit tests is
like driving down a California freeway at rush hour, blindfolded.
You're bound to run into an unexpected problem. Read the

Write Once, Run Anywhere Web Services
Sandeep Chatterjee, Ph.D.
published: April 22, 2002 The Java
programming language gave developers a real ability to write a
program once to run on many platforms. Yet, portability is more
complicated than just program execution. It involves making an
application available across a wide range of platforms and devices.
As IT organizations become more involved in creating web
services and applications that use them, developers subsequently
begin drilling into ways for immediately utilizing the new
technology. What's often overlooked are challenges further down the
road, such as maintenance and portability. Many developers haven't
yet made portability a priority with web-service applications, but
they should if services are to be made truly accessible from
anywhere on the internet via standard protocols. Portability
of web services and their associated applications has to do with the
complexity of managing the plethora of servers, clients, hand-held
devices such as PDAs, cell phones, and digital-entertainment
centers. This wide variety of devices makes supporting an
application very difficult and expensive. For example, an
application may want to make an MP3 file available to a user from a
music service, whether that user is sitting in front of a PC,
digital-entertainment center, or hand-held PDA. When the application
is running on a digital-entertainment center with high-speed network
access, the goal may be to optimize the quality of the music
playback and perhaps minimize the cost of the web service used. On a
hand-held PDA, the application may need to be optimized for audio
decode and playback, thus reducing network-bandwidth requirements.
These represent difficult porting challenges. And, it is
prohibitively expensive to manage all possible devices and
platforms. What is needed is a bridge to connect application
requirements with web-service capabilities. Read the full

HP Application Server 8.0 and WebGain TopLink
4.0 Plug In
Object/relational mapping addresses the
issue of persisting objects in relational databases. Objects
typically reside in system memory at execution time. In order to
allow these objects to persist between executions, it is necessary
to save them to a permanent storage facility, usually a relational
database. There are various ways in which to go about implementing
the persistence layer, some more specialized than others.

User-Centered Design Tips and Tricks
It is important to ensure that your
products are usable and useful to your target audience. Adopting a
user-centered design (UCD) approach to product development can help
ensure this. By incorporating UCD, you will keep the end
user at the center of product and design decisions. This helps to
make the development and design process as objective as possible.
The product design will be affected less by whim and more by
statistics and user reviews. Read this article: http://www.hpmiddleware.com/newsletters/hpdevelopernews/tips/may02_01.html
