Happens much since Java 1.2, 1.3? Yes and not. We are starting to publish
SCBCD Study Guide for you who is specializing in leveraging the Java
2 Platform, Enterprise Edition (J2EE) platform technologies. Despite to fact
that this guide is for J2EE 1.3 you will get 95% of knowledge to pass 1.4 exam.
By the way if you did not know, this certification is just one exam, but
requires that you passed any certification for Sun Certified Programmer for Java

Identify the use, benefits, and characteristics of Enterprise JavaBeans technology,
for version 2.0 of the EJB specification.
Enterprise JavaBeans architecture is the standard component architecture for building
distributed object-oriented business applications.
Enterprise JavaBeans architecture makes it possible to build distributed applications
by combining components developed using tools from different vendors.
Application developers do not have to understand low-level transaction and state management
details, multi-threading, connection pooling, and other complex low-level APIs.
Enterprise JavaBeans applications follow the Write Once, Run Anywhere™ philosophy of
the Java programming language.
The Enterprise JavaBeans architecture addresses the development, deployment, and runtime
aspects of an enterprise application’s life cycle.
Enterprise JavaBeans architecture defines the contracts that enable tools from multiple
vendors to develop and deploy components
Enterprise JavaBeans architecture is compatible with the CORBA protocols. This allows
remote invocations on session and entity beans from J2EE components that are deployed in
products from different vendors.
Defines the integration of EJB with the Java Message Service. Introduces message-driven
beans (MDB) - a stateless components that are invoked by the container as a result of the
arrival of a JMS message (MDB does not have home/home-local or remote/local interfaces).
Provides a local client view and support for efficient, lightweight access to enterprise
beans from local clients.
Provides improved support for the persistence of entity beans.
Provides improved support for the management of relationships among entity beans
(Local CMP Beans only).
Provides a query syntax (EJB QL) for entity bean finder and select methods (CMP only).
Provides support for additional methods in the home interface (business logic methods via
