Long time since I worked on OS/400(last time is V4R4), so I am not that updated yet.
But first of all, you can access
www.redbooks.ibm.com find bunch of redbooks on WAS on iSeries(OS/400).
Second, I think WAS3.5 SE is managed via browser? Or you can download the adminclient dynamically after your websphere is started?
You mean you cannot find the QEJB library on OS/400? You may look them up under "/" filesystem. I don't think they are part of the QSYS file system.
You can verify your installation with wrklicpgm?
Hope it helps a little bit, btw my first
EJB product experience is Tangeh on OS/400(before it is acquired by BEA) 2-3 years ago...
