1. SCEA certification Alain Hsiung, Ideartis Java Users Group Switzerland Technopark Zurich, 5.12.2003

2. 2 Content  The exam  Part I  Part II  Part III  The schedule framework  Working in group

3. 3 Motivation  Highest J2EE certification  31 certified SCEA (aka SCJA) in Switzerland (22.9.2003)  92% succeeded part I, 77% part II+III

4. 4 The exam  Part I: 48 questions, multiple choice, 1h 1/4, pass score 68%. n Hint: 16 questions = 20mn, mark unsure questions, pass through marked questions: 15mn  Part II: project, unlimited time (1 year), pass score: 70%. n Deliverables: 1 class diagram, 1 component diagram, sequence diagrams, assumptions. n Hint: use OOA/OOD methodology. Deliver a section on „design decisions“ (including the design patterns you chose).  Part III: 4 questions, essay, 1h 1/2, scored with part II. n Hint: anticipate questions concerning your architecture.

5. 5 Part I: objectives  Common architectures  Legacy connectivity  EJB, EJB container  Protocols  Applicability of J2EE technology  Design Patterns  Messaging  Internationalization  Security

6. 6 Part I: preparation  [course „Architecting and designing J2EE applications“, SL-425 Sun Edu]  Book: SCEA for J2EE Technology Study Guide, Sun Press n Good overview on the main topics n But topics missing: Common architectures, Legacy connectivity and Messaging. n Not enough details (other readings are necessary)

7. 7 Part I: preparation  More detailed readings n www.ideartis.ch (under news) n www.bm-one.com/Se/scea1.htm n www.leocrawford.org.uk/work/jcea/part1/ n saloon.javaranch.com  Mock test n www.whizlabs.com/scea/scea.html n highly recommended, also poor quality

8. 8 Part II  [Take an OOA/OOD course]  Use OOA/OOD methodology!!  Continuously write down assumptions  Look at many hints in my discussion thread on javaranch forum  Think as an architect, not a developer  Rewrite the use cases in your (better) terms, draw an activity diagram, a deployment diagram and user interface outputs for yourself; it helps.  Take time to make the class diagram solid (most failures are there)

9. 9 Part II  Component diagram for J2EE n There is almost no litterature n Use J2EE design patterns n Read the case study in the SCEA Study Guide  Make the diagram layout clear and notation (stereotype, labels, names, comments) consistent  Use a „real“ UML tool n Like Together, Rose and MagicDraw n Because correct syntax is scored

10. 10 Part III: preparation  Very easy if you have done part II yourself.  Anticipate a few questions on service-level requirements and key design patterns concerning your architecture n scalability n maintainability n security n session handling n persistence

12. 12 Working in group  Team building n 2-3 persons n Start and duration match  Information platform n For meetings, documents n Hint: use smartgroups  Discussion forum n Worldwide n Hint: use javaranch forum  Ethic: part III assignment is the same for all candidates. n Hint: discuss principles and methodology, not concrete design and domain details. duration (days) experience very high (50h) high (100h) medium (200h) effort 2h/d2550100 4h/d12.52550 8h/d6.2512.525
