I understand that the questions for Part I of the exam deal with EJB 1.1 (and 1.0) I was wondering if part II also had these constraints? Most of the Design Patterns that I know and use are only valid for EJB 2.0. Do I have to re-learn all of the outdated patterns?
Thanks

SCEA part I covers JMS which is part of the EJB 2.0 spec. Knowledge of the out dated patterns will be handy on a project that uses them. And it's always handy to know why things are. Unless you like to see history repeat itself.

You can use J2EE 1.0,1.1,1.2,1.3 or 1.4 - but you have to document your decision!!!

Hi ,
Are the Core J2EE Patterns as described in Deepak Alur et al, outdated with EJB 2.0?
I thought the main change was :
  • the inclusion of JMX in the EJB spec.
  • new contracts for entity beans with container-managed persistence to address the limitations of the field-based approach to container-managed in persistence in the old spec.

  • How many J2EE patterns are affected by this ?
    regards

    Hi,
    I think most of the patterns remain.
    But Local Interfaces remove much of the motivation behind Composite Entity.
