have <load-on-startup> in my servlet's web.xml, but does happen when I have <load-on-startup>
in the web.xml.  Also, BTW, if I stop then start the servlet app using the Tomcat manager
app, I don't get the NullPointerException.

vs. not being in the web.xml?  Doesn't Tomcat just load and call the servlet's init() method
when the <load-on-startup> is present?  I'm kind of guessing it may be a timing type
issue, as in my servlet's init() method, I initialize the Oracle stuff.  My initialization
call returns, but it may be that there's still something going on behind-the-scenes that's
not quite done.

Mark,

For the record, it turned that there was a bug in the Oracle SDK, as you suggested.  I got
a patched SDK JAR, and the problem got fixed.

Thanks,
Jim
