Version 1.3 beta 2 of the Java 2 Platform, Enterprise Edition (J2EE) is now available from Sun Microsystems. This latest release includes a new specification for Enterprise JavaBeans (EJB), an architecture for distributed enterprise software components. The specification gives programmers cross-platform portability, ease of development and deployment, and enhanced performance.

The EJB 2.0 specification includes:

Support for multiple tools, databases, applications servers, networks, storage devices, and vendors.
Integration with Java Messaging Service (JMS) through Message Driven Enterprise JavaBeans for legacy data and multi-client interoperability.
Improved container-managed persistence for ease of data modeling and portability.
A query language for rapidly finding and exchanging information and EJB relationship support for faster deployment and improved performance.
Increased network interoperability support for EJB components through Internet Inter-ORB Protocol (IIOP), an object-oriented protocol that allows distributed programs written in different programming languages to interoperate.

Overall, the latest J2EE Software Development Kit (SDK) provides Web service developers with greater XML support, performance, flexibility, simplified integration, improved portability, and interoperability among J2EE servers. The J2EE v 1.3 beta 2 SDK also features enhanced XML support through a variety of robust Application Programming Interface (APIs).

These enhancements include:

Implementation-independent support for parsing and transforming XML documents with the Java API for XML Parsing (JAXP), giving "plug and play" support for a variety of available parsers.
XML translation and filter support for dynamic Web publishing based on Java Servlet and JavaServer Pages (JSP) technologies.

The new J2EE SDK also provides expanded support for the JMS API, including:

Support for building asynchronous applications, which allow business processes within an application to operate independently and hand-off tasks as needed.
Core support for Message Oriented Middleware (MOM).

The latest J2EE SDK is available for download now at: http://java.sun.com/j2ee/j2sdkee-beta/index.html .
