memory leak in 4.0.2
by Mark Proctor
For stateful sessions a memory leak has been found, and fixed, for 4.0.2
http://jira.jboss.org/jira/browse/JBRULES-1279
We will release 4.0.3 early next week that address this issue. Stateless
sessions are not affected, but if you are using stateful with lots
sessions on the same rulebase then its recommended you stay with 4.0.1
until we release 4.0.3 next week.

eclipse 3.3
by Mark Proctor
I've just updated the build system to use Eclipse 3.3, this means on the
first time you use it there will be a delay while it downloads the new
Eclipse and GEF artifacts to the "local-eclipse-drop-mirror" folder.
Kris has updated the eclipse project so it should work.
Hudson is doing its first build of this (will finish in about an hour
from now, due to download), #879, if that finishes successfully you
should be able to download the eclipse 3.3 plugin and play with it - and
hopefully find any regressions :)

Have fun

Expressivity in business rules.
by Javier Chamizo
Hello all,
I am doing an study about differences between business rules and
semantic web rules and came up with a doubt.
While in semantic web there is a need in having decidable rules,
frameworks such us Pellet works with rules considered DL-Safe that
guarantees the decidability; business rules engines instead try to offer the
more expressivity possible. Does it mean that business rules are not
decidable? Why such difference?
Thank you very much

Re: [rules-dev] Documentation: BRMS on Weblogic using MySQL instead of Derby Database
by Fernando Meyer
Hi Paul,
I think you did a great job documenting this covering both mysql and
weblogic. you haven't missed anything.
You can keep the docs on your wiki and also copy/publish into the
jboss-drools Wiki ( http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossRules )
that is the preferred source for Drools' related information.
Again Thanks for your contribution.
Regards
