Thanks Jeanne for your guidance.

This question is from my company's exam.

Thanks Frits!
I was having the same understanding. :-)

which implicit object is NOT available to the jsp page?
<%page isErrorPage='false' session='false' isThreadSafe='false' %>
1) page
2) pageContext
3) session
4) exception
I have confusion between opinion 3 and opinion 4. Please guide.

Hello Ranchers,

It gives me immense pleasure to inform that I have cleared SCEA/OCMJEA exam with score of 139/160.
I appeared for the exam in 25th August.

I would like to thank all the members of this forum for providing me valuable information.
There were certain concepts on which I was not clear and even google search results were not of much help, at that time this forum was the only source of help.

Special thanks to Jeanne Boyarsky, Ashutosh Sharma, Krzysztof Koziol, Saket Mittal, Nilessh Ganu, Youssef Ben Kaddour El Wazzani, Rajan Choudhary!

I am impressed by your score in sections other than deployment diagram!! Anyway, hard luck for deployment diagram, what was your assignment? I am also surprised by the reason stated "deployment diagram is incomplete"!!

Hi Nilessh,

That is fine as per Application Controller J2EE design pattern, A front controller can delegate the request processing to Applicaiton Controller.

FacesServlet of JSF is example of FrontController and Managed beans are Application Controllers.

I have not shown any validators in any of my diagrams (As per example in Cade's book). However there is no harm in showing validators. The detailed the better.

Hi,

I have added descriptions in all other diagrams except class diagram and I am not able to write more than 5 line description for class diagram as my system overall design has been included in component diagram. Shall I explain cardinality between business objects as description?
Although it is very much displayed in diagram?

Please provide some topics that should be specifically part of class diagram desciption.

Thanks!

Hello Ranchers,

Individual Controllers are displayed in sequence diagrams (BidController), Also in class diagram they have displayed a single controller(This descripency is a already being discussed in separate thread), but what about component diagram? I think controllers should also be present in component diagram, just below the JSPs in presentation tier. Right?

Please confirm my understanding.

Thanks!

Hi Nilessh,

1) Even though FacesServlet is final and we can still redirect/delegate to specific controllers on basis of URL pattern configured in FacesServlet. Say /ABC/* will redirect to ABCController.java and /DEF/* will redirect to DEFController.java.

I agree that in Cade's book they have not refered BidController as managed bean, because they have not taken any framework into consideration. But in JSF framework managed bean can do the same work that is done by BidController in Cade's book.

2) I am planning not to show any validator in any of the diagram, in order to be in-sync with Cade's diagrams.

Fellow Ranchers, Please share your opinions on both points!

Thanks a lot!! I will add descriptions for every diagrams now.

Hello Ranchers,

Does it make sense to add extra description for class diagram, component diagram and deployment diagram?

I feel that sequence diagrams are good candidate for adding description for explaining flow, but it will not make much sense to add description beneath class diagram.

Please share your views.

Thanks!

Thanks Nilessh for highlighting other benefits of using SLSB as WS-Client!

Saket, Please check below mentioned thread for more information.

Hi Saket,
Implementing WS-Client as SLSB will improve scalability because its instance will then be maintained by container.
