In this tip, learn about the different solutions available for passing binary data (typically files) to a Web service.
The evolution of Web service protocols has gone from supporting very simple requests with simple parameters to fully supporting modern, object-oriented languages. XML-RPC, arguably one of the earliest forms of Web services, only supported simple types -- strings, integers, booleans, and the like. SOAP took this one step further with its encoding rules for objects. The last step -- improving on the binary -- came with SOAP with attachments.
SOAP with attachments was originally introduced as an extension to SOAP 1.1, and it is supported by the major SOAP kits. Although SOAP 1.2, the official W3C release, does not support attachments yet, work is under way to include them in the (ideally) near future.
A simple introduction to using PHP and MySQL to create XML Web Services. In this tutorial you will be shown how to create dynamic RSS news feeds from a backend MySQL database, PHP source code included.
This presentation offers an overview about UDDI (Universal Description, Discovery, and Integration), a specification for distributed Web-based information registries of Web services.
XML is a critical ingredient in peer-to-peer information sharing schemes, including grid computing, instant messaging, and Web services. This article explores the cutting-edge efforts intended to create a unified P2P fabric based on adaptations of existing XML technology.
In the Deploying Web services with WSDL series, htis article will explore all major technical aspects of creating, deploying, and publishing Web services -- from Web Services Markup Language (WSDL), to Simple Object access Protocol (SOAP), and Universal Description Discovery and Integration (UDDI) registries. Part 1 focuses on WSDL authoring: You will learn how to manually create a WSDL interface, and then compare your effort with the output of a WSDL authoring tool.
