SilverStream, HP, Systinet update UDDI tools

Hewlett-Packard and Silverstream Software Inc. on Monday announced new tools for UDDI (Universal Description, Discovery, and Integration) directories.

UDDI is the de facto standard for building registries that house Web services, and from which Web services can be accessed and consumed.

Palo Alto, Calif.-based HP, which last month began hosting a UDDI-based business registry, announced this week that it has upgraded the open-source UDDI4J (UDDI for Java) API to meet UDDI 2.0 modifications.

UDDI4J is a Java class library that IBM Corp. originally made available as open source that supplies an API for interacting with a UDDI registry. HP and IBM, along with SAP AG, intend to make UDDI4J a universal API for Web services registration.

Billerica, Mass.-based SilverStream announced eXtend JEDDI (Java Enterprise Discovery, Description, and Integration), a UDDI implementation that is now available for download.

SilverStream is hoping that the free developer edition of SilverStream eXtend JEDDI will incite developers to use UDDI for posting, managing, and sharing Web services both publicly and internally.eXtend JEDDI is currently available in beta form as a download. The download is a tool that offers users the ability to determine limits for how many businesses, services, and service type definitions can be published per user; the functionality to trace incoming and outgoing messages; and an error log for tracking performance.

Meanwhile, startup Systinet last Friday announced its WASP (Web Application and Services Platform), UDDI 3.0 Enterprise beta 1, which is a private UDDI implementation. In addition to the UDDI piece, Cambridge, Mass.-based Systinet's platform includes functionality for creating, publishing, and consuming Web services.

In addition to HP, IBM, Microsoft Corp., and SAP host public UDDI directories.

But experts say that despite the backing of the biggest Web services players UDDI directories have been somewhat slow to catch on.

"Basically, nobody is really using UDDI yet," said Roy Schulte, an analyst at Stamford, Conn.-based consultant house Gartner Inc.

Schulte continued that he expects UDDI to become more widely adopted in subsequent versions, although it won't be a requirement for all Web services.

"Many Web services will be implemented without UDDI. All you need to connect systems is SOAP (Simple Object Access Protocol) and XML," Schulte said.
