Developing Web Services in Java

Duration:	3 days
Type:	advanced

Description

Prior to JSE 1.6 and JEE 5 support for Web Services in Java was fragmented and overly complicated. In the newest evolution of the Java platform Web Services are simplified, standardised and fully integrated. This makes it much easier to write code which interoperates with .NET components written in C# and VB .NET.

This course introduces the latest methods for developing Web Services in both JEE and .NET. Delegates create Web Services on both platforms and learn how a client from one platform can access a service developed using the other. The course can be delivered using either NetBeans 6.1 or Eclipse Ganymede.

Prerequisites

Delegates must have several years Java and XML experience, preferably gained developing JEE Web Applications. Some prior exposure to C# and ASP .NET is helpful but not essential.
