John,

 

Do you want to know what the real difference is between JBOSS and WAS
besides the cost:  JBOSS WORKS!!!  

And i am not joking. I have not had any luck with any of the WAS
appservers except for the freebee IBM gives called 'Community Edition'
which is really a suped up version of TOMCAT.

JBOSS, SUN appserver, TOMCAT all work relatively effortlessly, but i can
bearly get a sample application working on z/os WAS 6.0, even after we
resolved the innumerable RACF problems.

 

Granted, we are behind on maintenance for WAS 6.0 and there is a big fix
to put on and 6.1 is the version we should be running.

I would go to support center with the errors if WAS was up to date, 

  but since someone else installed the thing and I am basically the only
one around here with any interest in it, it is the low man on the totem
pole as far as maintenance is concerned. 

 

By the way, you can basically just copy a Windows installed version of
JBOSS onto z/os Linux and run it with barely any changes.

I doubt if you can do that with any of the WAS appservers, although i
have not tried.

You've just hit on the real problem in getting anything new onto z/OS in
preference to another platform. You really CAN run these things pretty
much anywhere you want and while there may be scalability or quality of
service differences here and there, you can always apply the old adage
and "hit it with a bigger hammer". It turns out that a lot of what we
mainframers have always thought of as firm requirements are actually
pretty fungible when there are $$ attached.
