Hi,
I am presuming that you are talking about Business Delegate and Session Facade pattern if not then what I am gonna say is redundant and you can safely stop reading at this point.
Business Delegate pattern is client's sole point of contact to the business layer that is responsible for asking the Service Locator to look up the Session Facade and invoke coarsed grained service onto it. It also takes care of caching the Remote of Facade as the look up is potentially expensive operation and should not be invoked multiple times by various times.
I finished part-I and am looking for downloading assignment can any one suggest how do I go about it . I am in USA right now.
Thanks
Deepak
Hope this helps
Understanding design patterns from GOF is like listening mahabarat from lord krishna himself go ahead if you can and if time and other resources permit you to do so but that may not add any significant value to your prep for SCEA - I. any other small bool like cooper can do the job equally well. This is not to suggest that book is not worth spending time and effort it definately worth more than that but please do not tell yourself while reading GOF that you are preparing for SCEA - I.
All the best

Hi ,
Do not have anything specific to comment apart from what I have said
and what is covered in most of the posts earlier. Still Cade,
whizlabs and a couple of notes can eaisly sail you through the high
seas (which actullay is shallow and wide). DO not overprepare if you
are looking to for any promotion in your company or if looking for a
change in job as a result of certification you may be disappointed if
you are based in india.
Thanks

Hello Everyone,
I am continuing the tradition of sharing the joy & observations with everyone. I scored 100% in each section except for security (50%) & EJB (88%). Though I have expected to barely pass the exam befored it commenced but was pretty confident to score well towards the end of it.
I do not have any impressive architecht ( I am looking for it) or EJB experience but have exposure to designing web based applications. All in all about three years in Java & j2ee PLUS A couple of other certs (UML, XML etc.)
It is Important to answer survey at the earliest as the clock started ticking when you are answering survey.
Questions were bunched except for security in my case it started with design pattern and in most cases more than one choices looked correct then you will have to look for most correct choise.
EJB is covered in depth but no DD type question. Life cycle mgmt of container was having many questions.
Many scenario based questions but if U are clear abt CORBA, EJB, JRMP, IIOP & legacy system kind of stuff then it will help U out
Jawaroski book has interesting chapter on security & Legacy connectivity I recommend it if U want precise and clear description of what to expect in the exam.
All in all I have a feeling that exam was pretty easy or I would say I was lucky enough to score so high. Never mind that but atleast expectations were belied and it left much more to be desired particularly when we are talking about most prestigious certification in the Industrry.
do not know anything abt part II can any one of U gmme the headstart atleast which posts links are intersting and must read before even thinking of downloading assignment.
Thanks

Hello shrinivas,
I mailed to the address U mentioned. No response. I need to buy voucher urgently. Can U send me the link where U got the link from. I searched for the link as well on google but no luck
Thanks
Deepak Arora
That's Fantastic, Could Any one provide me with the detail where to send the DD and in the name of whom.
I am planning to appear for the SCEA-I soon, can I buy voucher for part-II & III at the same time (to avail the discount)
if I could not take part-II/III or both & if Sun introduce new exam then whether I will have to appear for part-I once again!!! that would be horrible to sit again.
hey any one please respond.
Thanks
pls read the following lines in the II para
"
also why modern languages are not supporting single static classification insted of dynamic multiple classification. "
as
"also why modern languages are supporting single static classification & not dynamic multiple classification."
Hello,
I am sorry this is not a direct reply to your question, though i would like to add that Java is a strictly typed language where every instacne is of some type where as smalltalk is not (what i gathered by studying design patterns by gamma). That means complier will not check the type of object before assigning it to any variable. (We do have same thing in java script too) this is multiple classification (Shouldnt it be no classification ).
whether my understanding of single & multiple classification is correct I would like others to comments, also why modern languages are not supporting single static classification insted of dynamic multiple classification. Fowler has suggested some ways to implement dynamic classification(i.e. at run time) in lang. like c++ can any one explain how.

Congrats esp. for narrow escape.Anyone preparing for IBM J2EE 483,or anyone who has taken it. I need advise on study material & level of difficulty

Hello ,
I am currently preparing for IBM 483 J2EE Cert.(For level 3 of JCert initiative) can any one tell me (I am sure that sandeep knows abt it) any simmilar forum exists for J2EE 486 certification, whether studying O'really EJB & Web development with JSP is enough for taking & passing the test what additinal readings are recommended. Level of toughness of the test & experience from those who have taken &/or passed the test.
Sandeep best of luck for ur visual Age for Jave exam this is my next goal (as you have advised) after taking J2EE 483.

Hello kosaic,
I believe the distinction between conceptual, Specification & Implementation perspectives is very very important conceptual level class diagrams is not a s/w entity it is all about what users actually thinks abt the world, it is the concepts in the minds of users e.g. hospital, Customer, Store, Bank etc. more or less these are real entities existing in the real world in time &/or space. there is no distinction b/n attributes & association in a class diagram which itself signify that we are talking abt real world & not s/w entities. Conceptual level class diagram are used during analysis phase of development.

When we are talking about class diagrams with the specification view, we are talking abt s/w entities & we are talking abt what a s/w entity is capable of doing. What are the responsibilities of this s/w entity(class) we are looking after interface of this class. Java beans are a good example of revealing it properties through introspection it is telling the JSP Container that it can tell the outside world abt its properties but not how.from a spec. perspective there is no distinction b/n generalization & realization, in fact generalization is one way of implementing realization.only public methods are drawn in a spec. pers. class doagram. It also implies the responsibilty of updating relationship with associated objects, if navigability is also present then who has the responsibility of updating relationship.

From impl pers. a class diagram include fields & public, private, protected methods.Now we are talking abt code & other nitty gritty.
Hope this helps

Hello Sandeep,
I agree with you on that . Our company do not have as many projects so we have a lot of time to spare. It is a better idea to prepare for an certification & improving our skill set.
Is it a good idea to persue J2EE (ICED) before taking IBM VA4J (ICSD)what factors one should take into consideration before taking this decision.
I think even you have taken J2EE before V4J.
Do you advise me to do the same. I feel more comfortable with J2EE test contents than i am with the test contents of VA4J
Deepak Arora
Hello,
Can any one suggest me is it possible to take J2EE for ICED before completing ICSD i.e. level 2 of JCert .If yes then is it advisable to take J2EE before passing one of the IDE or Application Server test of level 2 .
I want to persue J2EE (Level 3)before taking VA4J of level 2 is it a right step to take or one should first complete ICSD before persuing ISED. What are the pros & cons.
