<font face="sans-serif" size="2">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>

It won't work out of the box. Given enough time and resources you could
probably make it work.<br>
