— a compact, practical 60-minute plan plus concrete migration tips to turn the bullet list into a useful seminar. (Acknowledgement: is right about starting earlier; made the obvious noise — the structure below is designed for a fast, focused delivery.)

  • 0–7 min: brief motivation and scope (why move from WebLogic 6.x: JDK/JVM support, bug fixes, spec compliance).
  • 7–20 min: prerequisites and compatibility (JDK level, JRockit option, J2EE/EJB versions to expect).
  • 20–40 min: migration path and demo checklist (inventory apps, update descriptors, run DDConverter / appc, recompile, test).
  • 40–53 min: common gotchas (classloader/third-party jars, JDBC drivers, security realm & JAAS differences, session/cluster behavior).
  • 53–60 min: wrap-up — rollback plan, staging checklist, and pointers to official docs.

Key technical points to cover in the body of the talk: WebLogic Server 8.1 implements J2EE 1.3 and provides an EJB 2.0 container, so emphasize descriptor and API differences when moving from very old 6.x beans. Use the product docs for precise compatibility claims and to show examples. (docs.oracle.com)

Practical migration checklist (suitable as a handout): inventory deployed EAR/WAR/EJB-JAR; identify JSP/Servlet/JSTL changes; mark any Java-5+ compiled classes; convert older WebLogic descriptors with DDConverter and validate with weblogic.appc; always recompile and run a clean deploy in a staging domain before production. The WebLogic EJB tools guide documents DDConverter and recommends recompilation after conversion. (docs.oracle.com)

JRockit was bundled and certified with WebLogic 8.1 as a server-side JVM tuned for server workloads; include a short slide on when to pick JRockit vs the Sun SDK and how to enable JRockit monitoring during testing. Also, plan for platform-specific caveats: Solaris 10 zones have special support rules and some features (for example, whole-server migration) have limitations in non-global zones — point listeners to Oracle’s supported-configurations notes. (docs.oracle.com)

Finish with a one-page “do-not-deploy” list: no direct production changes without a rollback snapshot, test database compatibility, verify third-party lib versions, and capture performance baselines (CPU/GC/response) so the audience has immediate, actionable next steps.
