<br><font size=2 face="sans-serif">Our application is stuck with Websphere
6/jdk 1.4. I want to use Guvnor for our rule management as we have
business users editing rules. Would it be possible to use drools
4.0.7 compiler in the application which would read the rules from guvnor
as source instead of compiled ? I realize that we would have to avoid
rule semantics that are new in drools 5. Could that work or are we
asking for trouble ?</font>
<br>
<br><font size=2 face="sans-serif">My fallback option is to stand up a
jboss server as a rules server and make requests to it via webservice calls.
But I was hoping to have tighter integration between our application
and the rules engine.</font>
<br>
<br><font size=2 face="sans-serif">Thanks for any input. </font>
<br>
<br><font size=2 face="sans-serif">FYI: we trying to migrate away from
our Pega rules engine to drools and I have found drools to be very refreshing
in a number of ways. Thanks for your excellent work.</font>
