EPractice Labs - Wrong answer????

The following Question is in the Mock Exam-1 of EPractice Lab.

Q: Which of the following are valid methods of an entity bean?

Choices given:

ejbCreate()
ejbPostCreate()
ejbStore()
ejbRemove()
findByPrimaryKey()

Correct Answers(by EPractice) - ejbCreate(), ejbStore(), ejbRemove()

My Answer: ejbStore and ejbRemove.

If ejbCreate() is an valid ejb method of Entity bean, then all of the choices given are valid methods. Please correct me if I am wrong?

Thanks,

Could you please recheck the question with upper and lower cases?

Note that choice b is -->ejbPostcreate() not ejbPostCreate()

findByPrimaryKey() is part of home interface not bean class. Hence the choices A,C and D are correct.

I agree with William. Howerever, the camelCase ejbPostCreate should be OK.

ejbCreate() is not part of EntityBean class. Please refer the Java API. But it's need to be defined in "implemented" entity bean class(ie.. Class implements EntityBean) for each create method in home interface.

Choice B is ejbPostCreate() - This method is not in EJBHome interface. But the "implemented" entity bean should have this method for each create method in Home interface.

findByPrimaryKey() is not part of EJBHome method. but it is mandatory to declare it in EJBHome of an entity bean.

Hence, ejbStore() and ejbRemove are the two correct choices for the given question. Please correct if I am wrong...

Thanks,

Hi Makesh Kumar Ramakrishnan,

Please find the actual question (with proper cases)

Q: Which of the following are valid methods of an entity bean?

Choices given:

Choice A: ejbCreate()
Choice B: ejbPostcreate() (note that c is in small case)
Choice C: ejbStore()
Choice D: ejbRemove()
Choice E: findByPrimaryKey()

Choice A: ejbCreate() � correct
Choice B: ejbPostcreate() �incorrect, because c is in small case
Choice C: ejbStore() - correct
Choice D: ejbRemove()- correct
Choice E: findByPrimaryKey()-incorrect (not a EJB Bean class method)

Hence Choice A, Choice C and Choice D are correct answers.

ejbCreate is not part of the EntityBean interface. But, the question is not "methods defined by the EntityBean interface", it is "valid methods of an entity bean".
