Java Training : Advanced Enterprise JavaBeans (EJB) Using WebLogic 6

This class uses lecture and extensive hands-on workshops to teach you advanced concepts and techniques of coding Enterprise JavaBeans.

Java Training Background

Enterprise JavaBeans is a specification that promises to greatly ease the creation of sophisticated transaction-based applications with minimal work. It does this by shifting the burden of writing the complex "plumbing" of such applications from the programmer to the middleware vendor. The application programmer need only be concerned with solving the business problem at hand. The resulting server application is not only portable to all platforms that conform to EJB specifications but it also encourages reuse through its modular design. EJB has quickly gained enthusiastic support by most middleware vendors, and it is expected to become the standard solution for Java-based transaction applications in the near future.

Note: This course addresses version 2.0 of the EJB specification as implemented in J2EE version 1.3 and WebLogic 6.1.

Java Training Platform

WebLogic Application Server 6.1 running on Windows NT 4.0 or 2000 Professional or Sun Solaris. If 6.1 is unavailable, 6.0 may be used. However it does not implement all the EJB features covered in the course.

Java Training Prerequisites

Fundamentals of EJB Using WebLogic or equivalent. A basic understanding of XML and XML DTDs (document type definitions) is helpful but not required.

Java Training Course duration

3 Days

Learn to incorporate Java Message Service and new message-driven beans into an EJB application
Learn to define and use container-managed security regimes in your WebLogic EJB application
Understand the differences between the latest version of the EJB 2.0 specification and WebLogic's implementation of it
