Java Platform, Enterprise Edition (Java EE) is the industry standard
for developing portable, robust, scalable and secure server-side Java
applications. Building on the solid foundation of the Java Platform, Standard Edition (Java SE),
Java EE provides web services, component model, management, and
communications APIs that make it the industry standard for implementing
enterprise-class service-oriented architecture (SOA) and next-generation web applications.
Java Platform, Enterprise Edition (Java EE) 5 is the
latest version of the premier platform for developing robust, scalable
enterprise applications. Here are some highlights:
- Easier development. The focus in Java EE 5 is ease of development.
With Java EE 5, there is less code to write -- much of the boilerplate
code has been removed, defaults are used whenever possible, and
annotations are used extensively to reduce the need for deployment
descriptors.
- EJB -- simpler, better. EJB 3.0 makes programming with Enterprise
JavaBeans technology simpler through the use of Plain Old Java Objects
(POJOs), it also introduces a new persistence API.
- Enhanced web services. Java EE 5 includes simplified web services
support and the latest web services APIs, making it an ideal
implementation platform for Service-Oriented Architectures (SOA).
- JSF, JSTL, AJAX, and more. Constructing web applications is made
easier with JavaServer Faces (JSF) technology and the JSP Standard Tag
Library (JSTL). Java EE 5 supports rich thin-client technologies such
as AJAX, technologies that are crucial for building applications for
Web 2.0.
