Build and deploy Java web services using SOAP, REST, and SOA architecture
This course enables participants to acquire the skills needed to develop applications in a distributed environment. It shows how to integrate potentially heterogeneous applications to make them interoperable by using web services suited to the Java language and the Java EE platform. Numerous hands-on workshops allow participants to develop, publish, and use their first web services while working with the appropriate standards.

Developers and project managers who need to implement Web Services in the Java domain
Prerequisites
Basic knowledge of XML and experience in Java development
What You'll Walk Away With
- ✓ Design web services aligned with SOA architecture and WS-I standards
- ✓ Develop SOAP and REST services in Java using JAX-WS and frameworks (CXF, AXIS, Jersey)
- ✓ Define and use service contracts with WSDL and manage SOAP messaging
- ✓ Process and transform XML data using JAXB, SAX, DOM, and StaX APIs
- ✓ Deploy, secure, and optimize web services and clients (handlers, MTOM, multithreading)
Training content
1 Introduction: SOA Architecture and Web Services

4 Interface with WSDL
- Role of WSDL in Web Services
- 5 key sections of a WSDL document
- Description of the contract/interfaces/operations in the portType section
