Re: Weird JavaMail problem

["Blair Wyman" <blairw@xxxxxxxxxx>]

I've never configured or used JavaMail on iSeries, but this (somewhat
dated) page talks a bit about it:

http://www.ibm.com/servers/eserver/iseries/developer/java/topics/javamail.html

What version of JavaMail are you running?  (latest is 1.3, IIRC)

Does running the application "verbosely"  -- i.e. OPTION(*VERBOSE) in CL,
or "-verbose" from QShell -- show javax.mail.Transport et al. being loaded
from your expected mail.jar?  (Just wondering if something might've snuck
into the classpath...)

What does the stack trace for your exception in java.mail.Transport.send0()
look like?  (I don't have source for JavaMail API, like you, but if I did
I'd look at the line numbers in the stack trace and see what the code is
doing at those points.  At least there's a chance that I could find out
*what* is null, and maybe even how it got there.)

Oh, and the obvious question; does the new V4R5 production system have Java
installed?  (GO LICPGM, option 10, and look for a few 5769JV1 entries.)

Just a few random thoughts...  HTH.
