I'm trying to create a simple test case using Arquillian, Seam and drools.

consequenceExceptionHandler can not be loaded by drools api because of javaassist manipulation and class loading in Jboss AS 7.

I changed following code to fix this issue

org.jboss.seam.drools.RuleBase.java

if (consequenceExceptionHandler != null)
        {
            log.debug("adding consequence exception handler: " + consequenceExceptionHandler.getExpressionString());
            Class handlerClz = consequenceExceptionHandler.getValue().getClass();
            if (ProxyFactory.isProxyClass(consequenceExceptionHandler.getValue().getClass()))
                handlerClz = consequenceExceptionHandler.getValue().getClass().getSuperclass();
            RuleBaseConfiguration rbconf = new RuleBaseConfiguration();
            ConsequenceExceptionHandlerOption cehOption = ConsequenceExceptionHandlerOption.get(handlerClz);
            rbconf.setOption(cehOption);
            ruleBase = RuleBaseFactory.newRuleBase(rbconf);
        }

components.xml configuration

<drools:rule-base name="flowRules" rule-files="flow.drl" consequence-exception-handler="#{cosequenceExceptionHandler}"/>
