KURSINHALT
The Developing Web Services Using Java Technology course provides business component and client developers with the information they need to create, implement, and deploy web services and web service clients using Java technology components and the Java Platform, Enterprise Edition 6 SDK (Java EE 6 SDK). Students will understand and appreciate web services as a realization of Service Oriented Architecture (SOA), and how to use the Java Platform, Enterprise Edition (Java EE) technology design patterns and best practices when designing web services. Students perform the course lab exercises using the NetBeans Integrated Development Environment (IDE) and Glassfish v3.Course Outline
