Some of the JDK 1.3.x implementations seem to have a problem with this - perhaps due to classloading as the field is definitely visible by inspection. Try an IBM SDK 1.4.x. Perhaps someone has been able to get this working with 1.3.x but evidence isn't in favour of it based on past feedback.
Jonlee, thanks for your reply.
Problem is that AIX 4.3.3 can not use SDK 1.4.x (AIX5.X at least).
Is there a jboss release working with SDK 1.3.1 under AIX 4.3.3?
Seems 3.2.1 release has some pb with JMS.
Try the older 3.0.x service but I can't be sure as I haven't specifically run that version on AIX. I skipped from 2.4.8 which does run with the SDK 1.3.1 on AIX to SDK 1.4.0 with 3.2.0.
Sorry I can't be of more help.
