It cannot be negated that software frameworks
play a very vital role for the software engineering community.
As frameworks put a kind of boundary and bring a set of
constrictions, it is, to some extent, a dampener. However on the
other side, frameworks halve the total work and facilitate
bringing out a spectrum of robust and resilient applications.
Programming complexities and workloads are gently and greatly
minimized. Further on, the number of bugs would come down
sharply due to the strict boundaries and a host of conditions
implicitly imposed in any framework. In a nutshell, frameworks
speed up the software engineering assignments by supplying most
of the common modules that can be reused across domains for
simplifying and streamlining the arduous process of application
development and maintenance. All the constructive and
contributory modules are implemented by experts, tested in
different scenarios, refined religiously and intelligently
incorporated within the framework and therefore its utility and
usability are definitely supreme.
Frameworks do a bit in moderating the
software development complexity and the pioneering service
orientation (SO) idea does a lot in minimizing the design
complexity of ICT applications. With the powerful emergence of
SO concepts, services have become the core building-block for
designing, developing and deploying service oriented systems
that are extensible and adaptive. Application architects and
programmers are called to think and visualise enterprise systems
in terms of self-described, autonomous, and interoperable
services and their purpose-centric interactions. There are
primarily two architectural styles for producing service-centric
applications: SOAP and RESTful approaches. As usual, developers
look for competent and standards-compliant frameworks for
bringing down the workload of service engineering, inspection
and configuration whereas managers are for cost-cutting.
Worldwide professionals and providers collaboratively have come
out with scores of open-source as well as commercial-grade
frameworks. Academics too chip in with their innovative ideas in
realizing versatile frameworks for the software engineering,
which is lagging behind the hardware engineering.
In this book, the authors have taken great
pains in concisely and compactly explaining the relevance of
Apache CXF framework for the fast-growing service field. The
first chapter starts with a brief about the web services
technology. They argue that among various web service
frameworks, CXF stands tall due to its distinct capabilities,
comprehensive set of highly reusable resources and enabling
toolkits. Both SOAP and RESTful services can be constructed by
leveraging this framework. There are several advanced features
embedded in the framework that goes a long way in extensively
helping out software engineers.
The second chapter describes a sample
application development (The order processing application) using
web services and the CXF framework. They have talked about
contract-first and code-first development approaches. The third
chapter insists about the importance of CXF frontends, which
help out in publishing and invoking web servers easily. The
fourth chapter is a very interesting chapter explaining about
all kinds of popular and pervasive transports such as http, JMS,
and local transports.
The first chapter revolves around the
advanced features of Apache CXF framework and they are explained
well with the sample codes, tips and techniques. The most
expected chapter is 6th one as I have been looking
for some practical information about RESTful services and how
they can be built quickly. The chapter 7 digs deeper in order to
throw some light on how RESTful services can be deployed using
this prominent and dominant framework. The chapter 8 is all
about the matured tools that come along with the framework in
order to automate several manual tasks. There are some inspiring
appendixes comprising valuable details for programmers.
On concluding, this book is a must for both
SOA-compliant service developers. The book comes out with a
clear explanation what exactly the Apache CXF framework and how
it can be handled smartly in order to rapidly come out with a
wider variety of reliable services and ultimately robust
applications. Authors, having acquired and accumulated a lot of
knowledge in designing and implementing services using this
framework, penned down an excellent book for beginners as well
as experienced ones across the globe.
