I started preparations on 4/1/2010 to 4/24/2010 and could average about 2-3 hours a day some more on the weekends.
I only read the links posted on this site, Ivan’s study guide MZ’s test and guide. I got 60% on MZ'’s test.
In the real exam, I did very well on UDDI, WSDL, JAXR, Architecture and JAX-WS. My weakest sections were interoperability, REST, JSON, SAAJ, SOAP 1.2 . I strongly suggest practicing on few mock tests and solving some theory questions. Read some general design questions around interoperability and WS architecture 15/65 questions were purely on architecture, interoperability and design.
Thanks to Ivan and MZ for the notes, it helped me cram. I suggest some additions around WS architecture, design, and interoperability.

Questions: 65
Required: 42%
Result: 71% (46/65)

My background: I have done WS and SOA for many years. But as most developers, I know very little of JAXR, UDDI, JSON, REST, SAAJ, SwA, SOAP and interoperability. I definitely learnt a lot in 3 weeks.

I would suggest you to also read Java Web Component Developer Certification by Hanumant Deshmukh. It has a good summary section for exam tips and covers at least 3-4 questions that was not in HFJS as mentioned earlier.

I had to take 80 questions 70 regular + 10 extra that were not to be scored.

The questions were not straight forward, I had one question on dynamic-attributes, one on SingleThreadModel and @variable directives in Tag which are not covered in HFJS. I also got the $75 practice exam from SUN, which was an utter waste as the questions were far too simple than the real exam. I had some tricky questions on Servlet-URL mappings and did worst in the EL sections. The J2EE patterns questions were more innovative than any pratice exams.

SCJP 90% SCBCD 90% SCWCD 89%

Passed SCBCD with 90%. Books read HFEJB also Sanghera - This books is better for EJBQL. Mock exams jdiscuss, Softlearn, Enthuware, ejbcertificate. Used all available notes online made some of my own too.

Difficult questions asked:-
EJBQL the drag drops were different from what i have seen in the mocks.

I had one that said which sql returned results ('Harry','Harry') that required some thinking.
One question i know I got wrong was how can an Bean developer get a UserTransaction.

The answers are from EJBContext.getUserTransaction() and from JNDI.

I did not know UT can be got from JNDI like this:-
UserTransaction utx;
utx = (javax.transaction.UserTransaction)

Two question that were confusing abt CMP Entity bean life cycle I had to make a choice between

1. the container deserializes the EJBObject in the ejbActivate
2. the container always calls the unsetEntityContext while destroying an EJBOject

Another for matching choices

1. Familiar with the operating env
2. Familiar with the run time env
(Deployer, Sys Admin)

1. Configures the resources
2. Provides auth for the resources
(Deployer, Sys Admin)

A client encounters an EJBException
1. Client is local
2. Client is remote
3. Client cannot assume that the method did not complete
4. Container could not find the method

(choose 2) ( I chose 1,3)

I did not get any fill in the blanks. I had at least 6 drag and drops and you cannot review the drag drop questions. Cause it will erase the answers!

I had an initial review with questions on my EJB competence. I was not sure if I had answered expert to all the questions my exam would be harder. So I answered intermediate.

I have been doing EJBs for about 1.5 years. And prepared for 2 months on and off mostly. Most of the effort was on the last 20 days. I got an average of 90 on all mocks and 72 on the HFEJB. Most of the question were familiar or the exact same from the mocks. But there were about 5-6 that were new.

you can use the security-identity flag and let the MDB run-as a defined role. You can also use the unchecked flag on the SB's methods.
Did you have any questions which did not mention the correct number of answers?

The only reason there is a CMR-FIELD-TYPE is for java.util.Collection or java.util.Set. If your CMR is return not a single value but collection then the DD lets you specify what is the return type. You dont need the CMR-FIELD-TYPE for a single value return (Say you are returning a String) This it will get from the abstract method return type.

-Hope this helps.
Hi I have been studying for 1.3 for couple of months. And since my company is paying for it and we use 1.3 (1.4) heavily i am still planning to take this version in a month. Are there many in this same sinking ship?

I had a one question regarding the 1.3 exams, for multiple choice would they specify the number of correct answers in the real exam?
