J2EE 1.4 delay won't slow Web services: developer
- By John K. Waters
Sun Microsystems (http://www.sun.com) last
week disclosed its decision to delay the release of its J2EE 1.4 spec until this
summer. Developers predict the move won't slow the shipping of Web services
slated to be completed this spring.
Santa Clara, Calif.-based Sun had promised to release the J2EE 1.4 spec
during the first quarter of this year. Sun officials blame the delay on the its
decision to fully support the guidelines promoted by the Web Services
Interoperability Organization (WS-I). Complying with the WS-I's ''basic profile''
specification, a set of rules specifying how to implement key Web services
specifications, officials said, requires a few months' more work.
According to Sun, adding support for WS-I basic profile to its existing
support for Web services standards such as WSDL, SOAP, ebXML and UDDI, will
allow J2EE technology to provide both the Web services programming model and
data model that enable developers to build end-to-end applications and services
that can be used on any Internet-enabled device.
''With support for WS-I basic profile, J2EE Version 1.4 demonstrates Sun's
commitment to open standards,'' contended Mark Bauhaus, vice president of Java
Web services at Sun. ''Sun is fully engaged in collaborative work with industry
organizations such as WS-I to help ensure Web services interoperability becomes
Brent Carlson, VP of technology and co-founder of Pittsburgh-based
LogicLibrary (http://www.logiclibrary.com), said the
delayed release of the J2EE upgrade shouldn't prevent vendors from rolling out
Web services. Carlson believes that the main 'value-add' of the 1.4 spec, from a
Web services perspective, is the integration of the Java API for XML-based
Remote Procedure Calls (JAX-RPC) into the mainline Java code base.
Currently, the JAX-RPC is packaged as a Java extension, which users are able
to retrieve and deploy into their development environments. Developers are
getting value from JAX-RPC today in its current state, Carlson said. Embedding
this package into the mainline J2EE definition will simply make application
development and deployment a bit easier.
''Obviously, life will get easier when [the JAX-RPC] is part of the mainline
J2EE packaging,'' he said. ''But we're rolling out Web services using the JAX-RPC
package today on our product. In general, we think it's good that Sun is being
sensitive to the WS-I activities.''
The JAX-RPC is part of LogicLibrary's flagship Logidex product, a software
development asset (SDA) mapping and discovery engine that represents complex
enterprise application environments graphically. The Logidex SDA Library is a
catalog of SDAs, their relationships to each other, the company's business
processes and the technical infrastructure. Users -- including application
developers, business analysts and architects -- can search this library to
identify the software assets that best match business and technical requirements
for application development and integration.
Logidex is designed to allow developers to link software applications to
business processes, enabling faster creation of high-quality Web services
applications. Logidex uses JAX-RPC within its implementation of its open
SOAP-based APIs, Carlson said.
