Designing Java Web Services, Java EE 5, Self-Study Course

This Designing Java Web Services, Java EE 5 course elaborates on the use of the Java Platform, Enterprise Edition (Java EE) technology design patterns. You'll design web services and discuss various web services features, like Exception Handling and Security, provided by the Java Platform, Enterprise Edition 5 (Java EE 5).

Learn To:

• Analyze web services opportunities.
• Design patterns and implement best practices for web services.
• Handle exceptions in web services.
• Implement web services-based design patterns as part of an application.
• Secure a web service using basic authentication.
• Implement message-layer security in web services.

Participate in Hands-On Lab Exercises

You'll perform these hands-on lab exercises using the NetBeans Integrated Development Environment (IDE). You'll deploy the web services and applications on the Sun Java System Application Server Platform Edition.
