In the course Java EE Web Services you will learn what Web Services are, how you can create Web Services in Java and how they can be accessed from Java and other platforms.
The course covers both SOAP Web services and REST Web services.
The various standards on which Web Services are based are treated, such as XML Schema, SOAP, WSDL and HTTP for REST Services.
In particular, attention is paid to the various Java APIs for Web Services such as JAX-WS 2.x, SAAJ (SOAP with Attachment API), JAXB (Java API for XML Binding) and JAX-RS.
Attention is also paid to what you should look out for to ensure that Web Services are interoperable between different platforms such as Java and .NET. Also the architecture of modern Single Page Applications with a REST service backend is discussed.
And finally, the various mechanisms and standards for the security of Web Services are discussed. This course covers the topics that are asked on the Oracle Java EE Web Services exam.
The course Java EE Web Services is aimed at experienced Java developers who want to develop Web Services in a Java EE environment.
To join this course, knowledge of and experience with programming in Java and Java EE Web Applications is required.
This course has a hands-on character. The theory is covered on the basis of presentation slides and is interspersed with practical exercises. Demos are used to clarify the theory. The course material is in English.
Participants receive an official certificate Java EE Web Services after successful completion of the course.
