What is SCBCD?

     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:

• Analyze, design, develop, and test an EJB technology applications
• Deploy an EJB technology application
• Integrate an EJB technology application with legacy application

What is business component?

     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.

How many EJBs?

     There are three kinds of enterprise beans:

1. session beans,
2. entity beans, and
3. message-driven 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.

Question : Describe all kinds of the persistence type.

Java Objects
Entity Beans using CMP1.1
Entity Beans using CMP2.0
Entity Beans using BMP

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.

I think so. Especially when you compete with the person who has a similar background like you. 
If you got such cert, you stand out absolutely.
