Re: [rules-users] BRMS on 1.4 using Retroweaver
Markus,
Can you give me details of what you've tried to get and the errors that
you're getting? I'd imagine at lot of the issues are JSF / GWT / Seam
related , on top of the 1.5 v 1.4 problems. I may be able to make some
suggestions when I get time - day jobs pemitting :-) On a unrelated
project , we did manage to get a similar app working on an older Sun App
Server; If I had to do it again I would spend my time to get a more
modern app server!
Remember that typically the BRMS is an editing tool used by 2-10 people,
so a case could be made for a 'local' Tomcat or JBoss. The rules can
then be exported from this and deployed on the existing production
Websphere (JVM version permitting) - no BRMS needed there.
