Cape Clear says whistle while you WSDL

Eric B. Parizo, Executive Editor

Cape Clear Software Inc. is looking to make it easier to develop Web services using Web Services Description Language (WSDL) with an updated version of its graphical development environment, WSDL

Editor 2.0.

WSDL is an XML-based language used to describe the services a business offers, especially in a Universal Description, Discovery, and Integration (UDDI) director, and to provide a way for individuals and other businesses to access those services electronically. It is derived from the Simple Object Access Protocol (SOAP) specification.

According to the Dublin, Ireland-based company, the standalone tool allows experienced and novice Web services developers to create and edit WSDL code using frameworks such as .NET, J2EE and CORBA.

Cape Clear CEO and cofounder AnnraÍ O'Toole said developing with WSDL can be difficult and tedious because of the verbose nature of XML.

"Sitting down and typing out all the angle brackets would give you a repetitive stress injury very quickly," O'Toole said. "The only way to deal with XML is to have a tool that's going to generate it for you, and that's doubly true of WSDL. Having a tool really simplifies the process."

This latest release not only adds support for building Web services from a large XML schema, but it also allows developers to use automated wizards that simplify work that involves proprietary or industry-specific XML schemas.

Other highlights include a process for creating different WSDL elements, such as service definitions, port types, binding, template operations and messages; capabilities supporting the latest WSDL specification, such as imports, faults, SOAP headers, multiple bindings and parameter ordering; and easier retrieval of WSDL files from across corporate networks, UDDI repositories and the Internet.

WSDL Editor 2.0 is available for free download from Cape Clear. It runs on the Microsoft Windows, Sun Solaris and Linux operating systems.

Thirty thousand programmers are using last fall's initial release, according to the company. "Undeniably, people are very attracted to things that cost no money," admitted O'Toole, adding that many companies are interested in Web services but are unable to buy new development tools because of cuts in their discretionary budgets.
