Java EE technology is rapidly gaining acceptance and many large and small projects are being implemented using this technology. Despite its maturity and relatively easy programming model (compared to CORBA, for instance), it is very easy to end up writing non-optimal applications. This is primarily due to the vastness of the technology and a lack of application development guidelines that help Architects, Designers and Developers leverage the technology.

This five-day course provides practical guidelines that are critical for successfully developing and deploying applications using the Java EE technology. It involves extensive hands-on labs that reinforce concepts discussed in lectures. The primary focus is on providing guidelines for JSP, Servlet and EJB (including Message Driven Beans) patterns that enhance application evolution and performance. The course is easily customizable to suit your unique requirements and goals.

Working in a hands-on environment, under the guidance of our experienced subject matter expert, developers will explore:

• Tag Libraries and how to leverage them in JSPs.
• Servlet design patterns
• Command pattern based dispatcher
• State pattern based controllers
• URL Mapper Pattern
• EJB Home Cacher Pattern
• Shadow-Method Pattern
• Understand Standard EJB design patterns including:
• Value-Object pattern
• Bulk getter/setter pattern
• Sub-set Value Object Pattern
• Common Interface Pattern
• Updateable View Pattern
• With and without Database trigger usage
• Synchronous Facade Pattern
• Asynchronous Facade Pattern
• Program Logic Factoring in EJBs
• Session EJBs and Iterator Pattern
