Have you looked at Liberty Profile yet?
Yes. It's attractive but there are licensing issues.
Your customers with CICS TS 5+ for
z/OS or WAS 8.5+ for z/OS licensing already have Liberty Profile licensing,
and some of them probably already use Liberty. If you think one or more of
your target customers won't have any of those products then just ask IBM
about OEM licensing if you haven't already. (It can't hurt to ask, at
least.) There's also a blanket Liberty runtime license (<=2GB heap) that
might be appropriate to your needs, but (again) ask IBM.
Are CICS customers allowed to run WLP outside of CICS?
Liberty Profile is obviously going to have the greatest z/OS affinities
(features, supportability, performance, security, etc.) So if it's there,
or easily obtainable, why not? I'd avoid needless complexity if you can.
Well I would agree on supportability because if we ship a web server
then we have to support it. The good thing
is that it's open source so we've got the source code to do just that if
the vendor is too slow to fix problems. Feature wise I can
quite easily put together my own stack using open source Java libraries.
A quick squiz at the WLP lib directory shows it's pretty much
using the same set of open source libraries. And there's a lot of stuff
in there I don't need that's just bloat. Our server serves a REST API
and a single page application so there's not need for JSPs etc.
Security is interesting. Kirk shared dovetails Tomcat SAF realm code
which was much appreciated. Using that as a base it's trivial to write
a Jetty login module that uses SAF authentication.
It shouldn't be too difficult to implement thread level security using
the Java SAF packages although I'm not sure if I want to do that.
