Iona looks to make Web services interoperable

Playing the peacemaker, Iona Technologies is aiming to make Web services built in J2EE (Java 2 Enterprise Edition) usable under .NET software and vice versa, company officials said Wednesday.

The Iona XMLBus, currently in beta, enables developers to build Web services on the Iona iPortal, BEA Systems Inc.'s WebLogic, or IBM's WebSphere and take advantage of services built on .NET.

XMLBus has passed interoperability testing with nine Web service implementations, according to Rebecca Dias, Dublin-based Iona's product manager for XMLBus.

Iona's XMLBus currently supports Java applications and EJBs (Enterprise JavaBeans), Dias said. "The next two desires for us in the short term are JMS and CORBA, and then eventually CICS and IMS," she added.

To demonstrate the interoperability, Iona has a .NET retail application with XMLBus that communicates via SOAP (Simple Object Access Protocol) to an Iona XMLBus Web Service that brokers book catalogs and quotes for bulk book purchases.

Analysts said that .NET and J2EE services typically do not interact, but that moving forward people will start to string them together. That is where building Web services will get complicated, and the need for interoperability will arise.

Dias said the XMLBus will be generally available in the fourth quarter. In the meantime, the preview is available free as a download at
