The Designing Java Web Services course provides business component designers with the information they need to understand and appreciate web services as a realization of Service Oriented Architecture (SOA). This course elaborates on the use of the Java Platform, Enterprise Edition (Java EE) technology design patterns in designing web services and discusses various web services features, such as Exception Handling and Security provided by the Java Platform, Enterprise Edition 5 (Java EE 5). The students implement the course lab exercises using the NetBeans Integrated Development Environment (IDE) and deploy the web services and applications on the Sun Java System Application Server Platform Edition 9.0.
