Cape Clear releases free WSDL editor
- By John K. Waters
[MARCH 4, 2003/ADT'S PROGRAMMERS REPORT] - Cape Clear Software last week made a version of its WSDL
editor available for free download. The new editor is designed to simplify and
encourage development of Web services applications with a graphical environment and pre-built wizards.
Web Services Description Language (WSDL) is one of the
key XML-based technologies enabling the development of Web services, along with
SOAP, UDDI and XSLT. Co-developed by Microsoft and IBM, WSDL describes the
protocols and formats used by a Web service. Through WSDL, developers describe
what a service does -- its functionality, specifications, outputs, inputs and accessibility methods.
As Web services development teams -- sometimes working
across various companies -- must carefully communicate when building these new
application integrations, a descriptive protocol such as WSDL is very important.
The Cape Clear product, which is designed to work with
existing languages such as .NET, Java, J2EE and CORBA, provides what John
Maughan, director of engineering at Cape Clear Software, has called a ''top-down''
approach to development. It is, essentially, a means of thinking about interfaces before they are coded.
According to Maughan, tools like this one are gaining in
popularity among Web services developers because they put WSDL at the center of
their development process. ''It facilitates good Web service design, enables the
reuse of existing data-type definitions, and can be used to automatically
generate service implementations without developer effort,'' he said in a
statement. Maughan claims that more than 30,000 programmers are using the first release of this tool.
The WSDL editor is also included in Version 4 of the
Dublin, Ireland-based company's flagship Cape Clear Studio tools suite.
Previously code-named G4, Cape Clear 4 is a Web services development,
integration, deployment and management product suite. It includes three integrated products: Studio, Server and Manager.
This release of the WSDL editor introduces a range of
improvements over the previous release, including:
improved graphical environment that makes creating and editing Web services faster and easier.
* New automated wizards that simplify
the creation and editing of proprietary and industry-specific XML Schemas.
* Support for large XML Schemas, which enables developers
to create Web services that interface to existing business processes.
* A simplified process for creating different WSDL elements
such as service definitions, port types, binding, template operations and
* Broader support for WSDL validation against WSDL schema and WSDL
* Advanced WSDL
capabilities such as imports, faults, SOAP headers, multiple bindings and
parameter ordering, as defined in the latest WSDL specification.
* Easier retrieval of WSDL files from across corporate networks, UDDI repositories or the Internet.
The free WSDL editor runs on Linux, Sun Solaris or
Microsoft Windows. It is available for download immediately at http://www.capeclear.com/wsdleditor/
