Hello Vibha,
I did not encounter any question with regard to ejb2.0. They were very basic and based on concepts of Session and entity beans.
there was one question whose one option in answers needs you to know Session Facade design pattern.
thanks

thanks

Hi Bhagawanlu,
As far as Applet is considered from exam point of view these things should be made clear before appearing in exam
1.Restrictions imposed on applet when downloaded on web(Sun's appets FAQ gives you a good idea of that, i will say understand
all the points defined there ).
2.next important thing is , how will you talk to legacy system from applet
( consider all cases including
a. firewall present
b. firewall not present
)
I found pdf file in yahoo scea_j2ee group in file section to be useful.
thanks

Hi ,
i passed part I on friday with 83% and would like to thank all java ranchers for there active participation in this group.
My experience with exam is
1. there were too many scenario based questions
2.Ejbs were pretty straight and easy.I read both the books (richard and ed roman).
3.one question which long description with port numbers specified .
4.I118 and JMS were very easy just the tutorials on sun site are enough.
5.very straight questions in Design patterns like one specifying the scenario and which pattern to use.
6.I lost marks in legacy connectivity only 40% .I could not understand two questions at all, in the sense what they are asking.I was not even able to correlate the answers with the question.
7.Two questions on Applet restrictions.
now I am on to part II and would appreciate if some one can help me from where to start and which book to read.
thanks

Hello JiaPei ,
How much close is www.moelholm.com mock to real exam? How much you scored in this mock in first attempt
Ed Roman says this in life Cycle diagram of stateless Session Bean that Container decides to move the Bean from ready pooled state to does not Exsist state when it thinks it does not need so many instances of the Bean.

Nitin
I think Craig is right.
calling remove() from client on Home interface only invalidates the EjbObject for that client and moves the Bean instance to pool , where it can be used by any other client.Container decides when to remove the bean.
Thanks Carl and definately i will be helping others.

Hi ,
I just cleared my SCWCD exam with 84 % and would like to thank everyone who have been posting regularly at javaRanch.
I would like to give special thanks to Carl and Miftah for there good notes, which definately are recommended.
I would personally recommend JWEBplus.
I had some experience before giving this exam and studied for 20 days.
Things which I followed were
1.Servlet 2.3 and JSP 1.2 specification
2.Took help of Tomcat 4.0 to look at the APIs
3 JSP1.2 Syntax card
4.Studied listener from APIs in tomcat and read JavaOne article
5.studied Pattern catalog from sun site for design patterns
6 Studied some topics for JSP from Professional JSP(Wrox)
7Used JWEBPlus for test.
there was no question on Filters and had one question on Front controller design Pattern

thanks

Hello Tim,
Correct me if I am wrong.Any initialization parameter for a particular sevlet written in
<servlet>
<init-param>
can be retrieved by
ServletConfig.getInitParameter()

and for the parameters to be available to all servlets
written in
<context-param>
can be retrieved by
ServletContext.getInitParameter()
thanks
nitin

Identify which Attribute Scope is thread Safe

Local variables
Instance variables
Class variables
Request attributes
Session attributes
Context attributes
I am still very confused which attribute scope is thread safe when we implement single thread model and which are when we do not implement Single thread model.
can anyone exlpain me this in details
thanks
