Jakarta EE Web Services

In the course Jakarta 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.

SOAP and REST

The course covers both SOAP Web services and REST Web services.

Web Service Standards

The various standards on which Web Services are based are treated, such as XML Schema, SOAP, WSDL and HTTP for REST Services.

JAX-WS

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.

Interoperability

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.

Web Service Security

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 Jakarta EE Web Services exam.

Audience Course Jakarta EE Web Services

The course Jakarta EE Web Services is aimed at experienced Java developers who want to develop Web Services in a Jakarta EE environment.
