Sun Releases Beta of Web Services Registry
- By John K. Waters
Sun Microsystems has released an early developer beta of a repository/registry
designed to help users locate and reuse Web services. The Sun Service Registry
combines an integrated repository for storing the metadata accumulated around
Web services with services lifecycle management capabilities.
The registry, which will be part of version 4 of Sun’s Java Enterprise
System platform suite, due sometime after the JavaOne conference in late June,
is designed to provide centralized access to discovery, use and reuse of Web
services, the company says. It supports both the UDDI v3 and ebXML Registry
3.0 Web services standards, and enables customers to “publish, manage,
govern, discover and reuse services within a broad range of applications,”
the company says.
Sun is a bit behind the competition with this release. Microsoft already includes
a basic UDDI registry in its Windows Server 2003. Both IBM and SAP offer UDDI
Business Registries. Oracle has its Application Server UDDI Registry. And several
smaller vendors offer similar products. Infravio’s X-registry, for example,
is designed to provide a single point of access for information about all Web
Services in an enterprise. The Systinet Registry, which also supports UDDI v3,
is designed to capture detailed SOA service description and usage information
into a centrally managed, searchable business services registry. And the Apache
foundation has an open-source implementation of the UDDI called jUDDI.
But it’s better late than never, says Gartner analyst Yefim Natis. “A
meta-data repository is a key enabling technology for SOA,” Natis says.
“It is safe to say that no long-term enterprise SOA initiative can succeed
without an integrated and searchable repository/registry.”
Sun cites several key features of the new registry, including “the ability
to uniquely define information models and relationships among metadata and help
to ensure conformance of published services and content for more flexible customer
environments.” The product is also designed to allow customers to manage
aspects of Web services to reflect their IT policies and to use event-based
delivery of information to support specific processes.
Sun plans to integrate several JES components with the new registry product,
including Access Manager for user authentication, Application Server deployer/administrator
for managing service lifecycles, Java Studio Enterprise service developer for
develop-deploy-test cycles, and a Portal Server for managing WS-Remote Portlet
and producer descriptions.
Sun reportedly will demo the new Service Registry at JavaOne. The product is
expected to ship as part of the JES R4 release in the fall. The early access
version, included in the 1.6 version of the Java Web Services Developer Pack,
will be generally available later this month, Sun says.
