Telecom web services are used for back-end and business-to-business communication. For example, they are used between a server-side application and an operator’s web-services gateway, which makes telecom network capabilities such as SMS, MMS, terminal status, WAP push and location available to the application.

The Telecom Web Services SDK has two parts: a library of Java SE components for Parlay X web services and a telecom network capability emulator for testing your applications. Parlay X web services are a standardized set of interfaces that define various high-level telecom web services; the Java SE components give you access to these web services as plain JavaBeans.

Parlay X web services allow developers to create applications such as SMS voting or ordering ringtones by SMS. Without the Telecom Web Services SDK, however, you need to know both the Parlay X web services standard and SOAP (Simple Object Access Protocol) in order to make use of the capabilities provided by the telecom network. These protocols allow your application to communicate with the operator’s web services gateway. With the SDK, plain Java is all you need to know.

Build with plain JavaBeans
With the Telecom Web Services SDK you can develop your application without having to bother about the details of the Parlay X web service interfaces and the SOAP requests associated with callbacks, security, MMS attachments and other telecom web services. The Java SE components help you develop any type of application: Java SE applications, web applications, Enterprise JavaBeans applications and clustered applications.

Test immediately
You can test your applications with the emulator included in the SDK before contacting a service provider. The emulator implements the features of a Parlay X web services gateway and the telecom network capabilities that it makes available.
