I made some progress but now getting massive exceptions. I changed the
components.xml to look like the drools example one:
components.xml
| ...
| <component name="ruleBase" class="org.jboss.seam.drools.RuleBase">
| <property name="ruleFiles">purchasingRules.drl</property>
| </component>
|
| <component name="purchasingRulesMemory"
class="org.jboss.seam.drools.ManagedWorkingMemory">
| <property name="ruleBase">#{ruleBase}</property>
| </component>
| ...
|
But now I'm getting a ClassCastException, and I have verified my jars
exactly(crosses fingers) mirror the ones in the example. I'm running SEAM CR2
with JBoss 4.0.5
