[rules-users] Using constants in drools flow

Mon Aug 24 22:05:59 EDT 2009

The Drools Flow XSD can be found in the drools-compiler jar.
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-compiler/src/main/resources/META-INF/drools-processes-5.0.xsd
You can define globals in the header section like this:
<header>
  <globals>
    <global identifier="list" type="java.util.List" />
  </globals>
</header>
