Description
|
|
The Java 2 Enterprise Edition (J2EE) provides an object-oriented,
distributed and cross-platform framework for developing and deploying
robust, secure and scalable E-Business and E-Commerce applications. In
this course, you will master advanced concepts, design strategies and
implementation techniques for building highly efficient and maintainable
production-strength J2EE based systems.
This course may be delivered on Rational Application Developer 6.0,
WSAD 5.1.2, or WebLogic Server 8.x. Please contact us if you need delvery
on other platforms.

Objectives
|
This course teaches an advanced set of concepts and technologies of the
J2EE 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:
-
Configuring application server's security settings to support J2EE's
declarative security features
-
Develop portable and extensible security features in a J2EE application
using JAAS
-
Master the transaction model in J2EE to develop applications that span
transactions over multiple transactional resources
-
Master the EJB QL query language to implement custom finders and
ejbSelect ejbHome methods
-
Design and implement asynchronous enterprise components using the
Message-Driven Bean
-
Master the J2EE Connector 1.5 architecture
-
Design and implement a model-2 framework for the Web tier
