If you are brand new to J2EE platform, start from SUN's J2EE tutorial, download the J2EE 1.3 version and documentation.
SCBCD stands for Sun Certified Business Component Developer. The current SCBCD certification exam is for Java 2 Platform, Enterprise Edition 1.3.
This exam is brand new in IT certification market, designed for programmers and developers who are responsible for designing, developing, testing, deploying, and integrating Enterprise JavaBeans (EJB) applications. It is also for those specializing in leveraging the Java 2 Platform, Enterprise Edition (J2EE platform) technologies used to develop server-side components that encapsulate the business logic of an application. Prior to beginning the Sun Certified Business Component Developer program, you must be a Sun Certified Programmer for the Java platform (any edition). For exam details, see the objectives
Another exam called SCWCD which stands for Sun Certified Web Component Developer, focuses on the Web tier (Servlet, JSP, etc.), The more information and difference between web tier and business tier can be found at http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Overview3.html#wp81104
The EJB technology business component developers will be able to:
Business component or business tier is a logic part in J2EE server. The code for meeting the needs of a particular business domain like banking is handled by enterprise beans, which is often called business component. The enterprise beans often called EJB stays on the server side, not on the client side. Don't confuse with Java beans which can stay in the client side. EJB is a logic specification, can not be a graphic part like Java beans. EJB can retrieve data from storage, process data (if necessary) and send data back to the client program.
The test will only cover EJB 2.0.
There are three kinds of enterprise beans:
A session bean represents a transient conversation with a client. When the client finishes executing, the session bean and its data are gone.
In contrast, an entity bean represents persistent data stored in one row of a database table. If the client terminates or if the server shuts down, the underlying services ensure that the entity bean data is saved.
A message-driven bean combines features of a session bean and a Java Message Service (JMS) message listener, allowing a business component to receive JMS messages asynchronously.

Sun website lists as 120 minute with 45/70 pass score. Here it is 90 minute with 36/59. Which one is correct? The trial test was 90 minutes with 36/59 pass score and the test number set as 311-90. The formal test is 120 minutes with pass score 45/70 and the test number has been changed to 310-90. There is no typo here. Thanks for pointing out the outdated information.
