Table 26 shows the CORBA IDL types for application method parameters and return values that XMLBus supports when creating a Web service. The table also shows the associated WSDL type mapping.

An overview about WSDL.

Using WSDL in a UDDI Registry 1.02

In a previous entry I wrote about passing and returning structured data using NuSOAP. While that approach worked when using a client written in the same version of NuSOAP, it didn’t work for more stringest clients which need well formed WSDL to create proxies for methods and structures.

Web Services using UddI & WSDL

Web Services Definition Language (WSDL)

This document is a proposal for recasting the Distributed Annotation Service (DAS) protocol 1.5 as a Web Service. The proposed Web Service API will be known as DAS 2.0.

In our previous articles we learned that SOAP is a very high-level protocol that mandates the structure of XML documents exchanged over some transport protocol. That's quite a vague definition. The vagueness of this definition makes SOAP extremely extensible and versatile, but it also makes interoperability a bit challenging. At a basic level, we start our quest to achieve interoperability at the transport protocol level.

XMLBus supports JavaBean type classes which are also known as structures. These data members can be the basic Java tyes (primitive and common class types), arrays of basic types, or arrays of structures. This means that a developer can create a complex Java object to serialize over the wire.

In order to use the WSDL system, you will need to install the DataDoc modules. This module follows the same approach as any CPAN module. Execute the following commands after extracting the contents of the DataDoc tar file.

The current BTP message set prohibits the authoring of a useful WSDL for the control and output protocols. In particular, the wrapper elements (btp:messages and btp:related-group) do not allow a WSDL operation to be correlated to a BTP message (other than the wrapper element.)

Glue supports an XML descriptor format for specifying the properties of a web service.

When generating a Java test server, there is a restriction on the characters that can be used as separators in WSDL portType and binding names.

This document explains how to use the P3P generic attribute with a WSDL 2.0 description in order to express a Web service's privacy policy.

We introduce the WSDL. This talk is based on:

The LEIF Network Tier contains a component called SOAPworX, a code generator that reads a standard WSDL file and creates components for accessing the service described. In the Network Tier, the generator creates client-side components.

To create a Web service from a WSDL file, you must first have the WSDL file. You can use one that exists on the Internet or you can have one in your IDE file system. In our example, we will use a demo WSDL.

The core technologies at the heart of Web services—WSDL, SOAP, and UDDI—are designed to ease interoperability. In particular, SOAP, a protocol built upon XML, is the fundamental Web service transport technology.
