Company profile

SanEd consulting is an IT training company which initiated its services in 2005 primarily as Sun Microsystem's authorised training provider. Our training portfolio was Solaris and Java focused. Later on we upgraded our portfolio and included authorisations from Veritas / Symantec and Oracle after aquisition of Sun. 

As the global IT market is rapidly changing and developing we must have accepted its needs and trends. Thus, beginning of 2014 we decided to "refurbish" our services and included new, young and perspective partners and together prepared number of interesting trainings you can find in our catalogue.

We are looking forward to successful cooperation with you.

Description

A comprehensive look at the state of the art in developing interoperable web services on the Java EE 6 platform. Students learn the key standards -- SOAP, WSDL, and the WS-I Basic Profile -- and the Java architecture that has evolved to build interoperable services and clients. We begin with an introductory module that covers both SOAP-based and RESTful services, and therefore both JAX-WS and JAX-RS.

But JAX-WS is central to the course, and we cover both WSDL-driven and Java-driven development paths, as well as message handlers and attachment support. With the new Provider and Dispatch APIs, it's now much easier to integrate SAAJ, JAXB, and JAXP code into services and clients, and we explore these strategies in depth as well.

 

Description

5 days

 

Prerequisites

  • Strong Java programming skills are essential.
  • Students must be able to read XML documents and to write well-formed XML by hand.
  • Knowledge of XML Schema will be helpful, too, but is not a strict prerequisite
  • Experience with other Java EE standards, especially servlets and JSP, will be very helpful in class, but is not strictly required.

 

Skills gained

  • Be able to describe the interoperable web services architecture, including the roles of SOAP and WSDL in component-based services and XML and HTTP in the REST architecture.
  • Understand the importance of the WS-I Basic Profile for interoperable web services.
  • Build JAX-WS services and clients that take full advantage of the automated data binding of JAXB.
  • Build WSDL-to-Java and Java-to-WSDL services, with equal facility.
  • Apply advanced techniques and best practices including proper exception handling, care around possibe polymorphism, and use of context and lifecycle services.
  • Use lower-level SOAP and XML APIs for services and/or clients.
  • Customize data binding by specifying specific type mappings or altering method or parameter names.
  • Incorporate binary data, such as images, into service and client code.
