As I said in my previous post I am posting some Important tips one should know the following things before taking SCBCD Exam: You should emphasize on following area: Security : What other tags should be written in <run-As> tag ? Whose responsibility is to define security role refrence tag? What other tags can be in security refrence tag and security role tag? Whose responsibilty is to define security roles ? What should must be define in a deployment Descriptor to use isCallerInRole(string s) method? What type of object is returned by getCallerPrincipal() method? What class or interface contains Programmatic security methods? What is requirement for Programmatic Security?
EJB-QL:
You should know how to write a query You should know whats illegal in EJB-QL query You should know about WHERE , FROM , IN ,AS clauses You should know about Pathexpressions You should know about collections You should know that ejbSelect<Methods>are written in bean class not in home interface You should know that ejbFind<Methods> are written in home interface You should know the difference between find and select method You should be aware of PrimaryKey field, class , type You should be aware of defining custom composite primary key class and the things it need to contain You should know that what variables should be part of both PrimaryKey class as well as the cmp bean? You should know about EJB-QL and Abstract Presistance Schema Entity Beans / Session Beans / MDB:
You should know Life cycle of entiy bean Memorize sequence diagrams Learn them inside out their Limitation from Specification Statless beans in context of transaction Statefull bean and conversational state Transactions: Know how to define CMT by using Deployment Descriptor Know how to define BMT All transaction attributes should be remembered You should know all things related to transactions and Exceptions Exceptions : You should know the difference between two System and Application Exceptions You should know actions and effects of these exception on container transactions You should be able to identify the exceptions Environment: You should know about JNDI-ENC and resources you can get from it Developers already taken exam can modify these to give better idea to new ones
I support the list you declared here. Nice initiative.

Great summary indee.
You were trained to handle mission impossible; 'difficult' should be a walk in the park for you.

Hi guys Thanks for good response I think we should make some EJB Quick Refrence Manual and hope with help of one or two more ranchers I can go for it . Any ways it would probably more benefical for developers to revise ejb as quickly as possible without using specification which almost all developers don't want to use and Oriely book also has a lot of repition which is time consuming.
Hi Syed AliRaza Zaidi, Just took the exam good to note your points, hope others will also follow the same. Thanks

We are also working on a book for SCBCD which should be in the market by the end of July 2003.

Syed, I quick reference will be very useful. I hate the 572 page EJB spec! The EJB spec has lot of valuable details but it is not very user friendly specially if you want to prepare for a cert exam. A concise handbook will be very valuable to lookup stuff and also to refresh our knowledge a day or two before the actual exam instead of reading the spec. I have taken the exam. Your tips were valuable indeed! If you are working on such a book I would be happy to help/pitch in! Thanks! Saurabh

With regards to the original post. Do exam takes only need to be aware of the "entity" bean life cycle or all the various bean life cycles. Having very little experience of EJB programming I need to be very precise on what I revise for the exam. Cheers,

Hi You need to concenterate on life cycle of entity and Session Beans as Life Cycle of MDB closely ressembles life cycle of Stateless Session Bean. As exam has 183 question It is covering every nook and corner of EJB Specification , there are some D&D's also from Life Cycle question Its better to memorize Sequence Diagrams
