Exam 287 is the same as 158 for the newer Websphere version i.e. WS5. Exam 158 was retired once but was later reinstated because of widespread use of WS4. If you are looking for Enterprise Developer Certification you take Exams 483 and 158 (for WS4); it is 484 and 287 for WS5. Of course 486 and Sun
Java 2 complete the requirements for Enterprise Developer certification for both versions.
WS5 support
J2EE 1.3 while WS4 supports J2EE 1.2; hence the related technologies are also to be taken into consideration.
Best wishes
