WebSphere Application Server V7.0: Concepts ... - IBM Redbooks

► Industry standard technologies enable clients to choose among platforms,
development tools, and middleware to power their applications.
► Platform independence gives flexibility to create an application once and to
run it on multiple platforms. This provides true portability to enterprise
applications.
► Embedded support for Internet and Web technologies allows for applications
that can bring services and content to a wider range of customers, suppliers,
and others, without creating the need for proprietary integration.
Java EE 5, the latest release of the Java EE platform, represents a significant
evolution in the Java enterprise programming model. It improves the application
developer experience and productivity with following new features:
► Latest specifications
– Enterprise JavaBeans (EJB) 3.0
– JAX-WS 2.0
– JSP 2.1
– Servlet 2.5
– JSF 1.2
► Java Development Kit (JDK) 6.0
► Usage of progressive disclosure
► Annotations and injection support to reduce complexity
► EJB development as Plain Old Java Objects (POJOs)
► Java Persistence API (JPA) to allow creation of simpler entities using
annotated POJO model
Another exciting opportunity for IT is Web services. Web services allow for the
definition of functions or services within an enterprise that can be accessed
using industry standard protocols (such as HTTP and XML) already in use today.
This allows for easy integration of both intra- and inter-business applications that
can lead to increased productivity, expense reduction, and quicker time to
market. Web services are also the key elements of SOA, which provides reuse of
existing service components and more flexibility to enable businesses to address
changing opportunities.
