Advanced JEE Training
This is a 7 week course specially designed for software developers with little or no exposure to J2EE but are looking to build large-scale, scalable, robust, secure, transactional distributed e-business systems using the advanced features of the J2EE platform. This course teaches advanced concepts and technologies of the JEE platform with an emphasis in the areas of performance, security, distributed transactions, advanced persistence mapping of components, asynchronous components and Web tier architecture. On completion, attendees would be able to:
- Master JEE architecture
- Design and implement Entity beans, Stateless and Stateful Session beans, Message Driven and Timer beans
- Develop Management Extensions
- Design and develop n-tier applications
- Master the transaction model in J2EE
- Design and implement synchronous and asynchronous enterprise components
- Design and implement a Model 2 framework for the Web tier
