Hi friends,
I have a few doubts, any input will be appreciated.

1.I did read somewhere that Wrapper classes shudnt be used in CMPS, may i know the reason.It is something related to the serializable funda.
2.Whats the difference between serilisation and marshalling.
3.In EJB 2.0 we have all methods within the bean as abstract, what if i wish to have a particular method using some logic?? cud i declare it??
4.I map CMPs to views, what will my create or update behave like.
5.Cud someone explain briefly the design patterns??
6. Why do guys around have to ask for a 3+ experience to hire u??

I can answer some of your questions
3.In EJB 2.0 we have all methods within the bean as abstract, what if i wish to have a particular method using some logic?? cud i declare it??

The abstract methods are the ones that map to container managed fields. You can add any other method you want. If that method needs to get or set some container managed field, it can just call the abstract get/set method.
4.I map CMPs to views, what will my create or update behave like.
I assume you are refering to views being read-only. In that case, I think you want to make your entity bean read-only as well. So it should not have any create method, and should only have public get methods in the remote interface for the container managed fields. You still need both get and set abstract methods in the implementation, but don't expose anything but the gets from the remote interface. Also, some app servers (WebLogic) have features to help optimize entity beans for read-only.
5.Cud someone explain briefly the design patterns??
There are very good discussions on this at http://www.theserverside.com

You mean "Must have 3+ years experience EJB2.0"?
This is part of the standard HR mechanism to ensure that no candidate who is actually competent will ever be passed to anyone who can tell the difference.
Sometimes I think they're just looking for another Ken Lay
... And the sad thing is, anything over 3-4 years in an IT product usually means that the product has changed so much that the original expertise isn't worth that much anymore. :roll:

Could also mean that the job is covert maintenance, the original team members having cleared off to get at more interesting projects...
