Replication is a process of synchronizing data among the participants (or
entities) in the operator cloud. The cloud acts as a single logical entity or
entry to the outside world. The goal of replication is to facilitate
uniformity and consistency in the data present in the UBR. This can be
achieved by the set of replication messages defined in the UDDI Version 2
Replication Specification. Nodes represent operators and are used
synonymously in the replication specification. Identified sets of entities
form the operator cloud.
This article looks at the importance of replication and its coexistence with
the UDDI service. I'll also cover the replication APIs that are implemented
by the operators and will discuss the business advantages. I assume you are
familiar with XML, SOAP, and UDDI.

The beta release of the Java 2 Platform, Standard Edition (J2SE) 1.5, started
gaining momentum in the developer community due to its potential improvements
to the language and its convincing feature set. J2SE 1.5, code named "Tiger,"
is being developed under the Java Community Process (JCP). The umbrella Java
Specification Request (JSR) for this release is JSR 176. This article
outlines the major features that are shipped with J2SE 1.5.0 Beta 1, which
was released in February 2004. The final RI and TCK are targeted to be
released in the summer of 2004.

As Web services technology becomes pervasive, the beta release of Java 2
Enterprise Edition (J2EE) 1.4, which focuses primarily on Web services, flags
a milestone in the Web services developer community. Sun's J2EE Reference
Implementation (RI) helps developers to easily understand the technology
through its robust implementation of the specification. The J2EE 1.4
specification (JSR-151) adds a lot of functionality to the platform. The core
theme of J2EE 1.4 circumvents Web services. It has incorporated most of the
Web services-related JSRs in its specification, including JSR-109... (more)
