Course Description:

SOA and Web Services represent a groundbreaking evolution in distributed computing. The concepts are not altogether new, but the application of them, and the unanimous acceptance of core standards like HTTP, XML, SOAP, WSDL, and UDDI, has paved the way for XML Web Services and service-oriented architecture. Developers are introduced to the core standards that enable Web Services, and provide them hands-on experience with implementations of the Java XML and Web Service APIs including JAXP, JAXB, SAAJ, JAX-WS/RPC, WSEE, and XWSS.

Who Should Attend:

This is an intermediate and beyond level web services training course, designed for J2EE developers and architects who need to identify, design, and implement web services.

Benefits of Attendance:

Upon completion of this course, students will be able to:

• Understand and work with Service-Oriented Architectures.
• Apply SOA Analysis and Design to the identification and implementation of web services.
• Understand and intelligently discuss Web Services and the core technologies involved.
• Develop and deploy real-world J2EE Web Services.
• Expose existing Java components as Web Services.
• Write Java components that access remote Web Services hosted by a third party.
• Read and understand a WSDL document.
• Parse, process, and respond to a SOAP message.
• Effectively use the tools and APIs provided by the JWSDP.
• Understand the concepts behind REST and implement a REST-based web service.
• Understand and work with the standards and technologies encompassed by WS-Security.
• Understand and utilize web service-related design patterns.

Prerequisites:

Students should have 1-2 years of working knowledge with Servlets and JSPs, and should be familiar with XML, Namespaces, and XML Schema.
