Greetings all,
I posted this to the Seam users forum and they recommended I post it here as well.
I am using Seam 2.0.0 and Drools 4.0.7. I am getting the following exception when my rule
is compiled on first access.
Rule:
package org.ebsinc.ia.rules
#list any import classes here.
import org.ebsinc.ia.entity.BenefitAnalysis;
import org.ebsinc.ia.entity.RetirementEligibility;
#declare any global variables here
rule "Verify FERS"
when
$ba : BenefitAnalysis(plan == "FERS")
$elig : RetirementEligibility(eligible == false)
then
System.out.println("FERS retirement");
$elig.setReason("ok");
end
components.xml
<drools:rule-base name="securityRules" >
<drools:rule-files>
<value>/security.drl</value>
</drools:rule-files>
</drools:rule-base>
<drools:rule-base name="retirementEligibility">
<drools:rule-files>
<value>/RetirementEligibility.drl</value>
</drools:rule-files>
</drools:rule-base>
<drools:managed-working-memory name="retirementEligibilityWM"
scope="event"
auto-create="true"
rule-base="#{retirementEligibility}" />
Exception:
