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

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

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

  4. The exam • Part I: 48 questions, multiple choice, 1h1/4,pass score 68%. • Hint: 16 questions = 20mn, mark unsure questions, pass through marked questions: 15mn • Part II: project, unlimited time (1 year), pass score: 70%. • Deliverables: 1 class diagram, 1 component diagram, sequence diagrams, assumptions. • Hint: use OOA/OOD methodology.Deliver a section on „design decisions“ (including the design patterns you chose). • Part III: 4 questions, essay, 1h1/2, scored with part II. • Hint: anticipate questions concerning your architecture.

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

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

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

  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. Part II • Component diagram for J2EE • There is almost no litterature • Use J2EE design patterns • 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 • Like Together, Rose and MagicDraw • Because correct syntax is scored

  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 • scalability • maintainability • security • session handling • persistence

  11. Schedule framework take exam at IBM, GKN, Migros, etc. register for exam at prometric buy voucher at sun register for exam download part II upload part II receive email take exam start finish study part I do part II prepare part III 100h effort 100h effort 4-6W 2W 1W • Read 1-3 chapters, take notes & meet to discuss lessons learned and issues. Iterate. • Do mock test, take notes & discuss lessons learned and issues. Iterate. • Make draft & meet to discuss issues. • Make a version 1.0 & meet to discuss issues.

  12. Working in group • Team building • 2-3 persons • Start and duration match • Information platform • For meetings, documents • Hint: use smartgroups • Discussion forum • Worldwide • Hint: use javaranch forum • Ethic: part III assignment is the same for all candidates. • Hint: discuss principles and methodology, not concrete design and domain details.
