[jboss-user] [JBoss Seam] - Re: Problem injecting drools WorkingMemory

[sjmenden]

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
