Web services development with Java EE
The use of web services offers the opportunity for integration of applications on different platforms. Java EE supports traditional web services, based on XML and SOAP, as well as RESTful services, using named resources in a URL and the HTTP and HTTPS communication protocol.
This course explains how to implement a service oriented architecture (SOA) in Java EE.
- creating RESTful services (APIs)
- using APIs in a browser or in a Java client
- building classic web services, using WSDL (Web Services Description Language)
- constructing a client that accesses the web service, based on SOAP
The main focus will be on the REST APIs. Additional aspects on error handling and security are discussed as well.
No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please contact ABIS.
Application developers who are going to implement and use web services, based on the Java EE platform.
One should be familiar with the concepts of web services (see course Distributed applications: APIs and web services). Moreover, a thorough knowledge of Java (see course Java programming) and basic knowledge of XML (see course XML concepts) is required.

Classroom instruction with exercises, using a Java EE IDE (e.g. Eclipse) and a Java EE runtime.
Zeer goede cursus.
Een heel uitgebreid onderwerp, dat gelukkig stap voor stap aangbracht wordt. De cursus is op erg hoog niveau. Veel voorkennis is vereist om te kunnen volgen
