Representational State Transfer (REST) is a new architecture for Web Services that is having a significant impact on the industry. Most of the new public web services from large vendors (Google, Yahoo, Amazon, now also Microsoft) rely on REST as the technology for sharing and merging information from multiple sources. Delphi XE supports REST through the DataSnap infrastructure, support for WebBroker integration, and the creation of JavaScript proxies for methods exposed by web service.

DataSnap XE is available exclusively in the Enterprise and Architect editions of Delphi XE, C++Builder XE and RAD Studio XE.

Featured Webinar

Marco Cantù presents: Building REST-based applications using DataSnap in Delphi XE

Join Embarcadero and Delphi expert Marco Cantù for an informative web seminar where you'll learn how to build web applications in Delphi XE with DataSnap, REST and jQuery.

DataSnap is a flexible multi-tier application development technology available in RAD Studio XE with options to create client applications in Delphi, C++, .NET, PHP and JavaScript.

This presentation focuses on a specific new feature of DataSnap in Delphi XE: the support for the development of REST servers with a JavaScript client.


Topics covered in this webinar will include:

  • Creating a DataSnap server in Delphi and looking at the Delphi and JavaScript code produced by the DataSnap REST Application Wizard
  • A focus on some of the server features - the data types you can return, the session management, the authentication and authorization support, and the filtering mechanism
  • How we can expand on the client side by using the jQuery library
  • We'll also see how we can use the Delphi server to generate some JavaScript to speed up and simplify development."
