14.2. Using rules from a Seam component

We can now inject our WorkingMemory into any Seam component, assert facts, and fire rules: 
@In WorkingMemory policyPricingWorkingMemory; 
@In Policy policy; 
@In Customer customer; 

public void pricePolicy() throws FactException { 
  policyPricingWorkingMemory.insert(policy);
  policyPricingWorkingMemory.insert(customer);  
  policyPricingWorkingMemory.fireAllRules(); 
}
