[rules-users] BRMS on 1.4 using Retroweaver

Markus,
Couple of Questions:
a) What version of Websphere are you using
b) Which JDK are you using - Sun or IBM?
c) How much access to do you to the WS production and Dev servers ; i.e.
will you be able to change security policies, replace core server jars
with more up to date versions?
My gut feeling is that you have 3 choices:
1) Try to 'retrofit' the BRMS into a previous JVM / Websphere version.
No guarantee that it will work nor that the changes needed will render
the production server unstable. You need three changes: Retroweaver the
code to 1.4, Add JSF to the App Server and overcome any differences
between the IBM and the Sun JDK. One change you might attempt; to make
three is madness!
2) Deploy BRMS on Tomcat / JBoss. It might go against corporate policy,
but either the business needs the BRMS functionality enough to accept
this, or they will *have* to choose options 1 or 3.
3) Use an alternative means for business users to write rules; e.g.
Decision Tables or train user in the use of the Drools IDE.
None of these are ideal. As bad as options 2 and 3 are, number 1 is even
worse; you could waste a lot of time (no guarantee of success) and very
quickly find yourself with an App Server that IBM will refuse to support
:-(.
