[rules-dev] Drools - Spring (IOC) - In progress

[Geoffrey De Smet]

Have you considered taking advantage of the BeanFactory interface (and 
probably ApplicationContextAware, InitializingBean and DisposableBean)?
It's spring specific, but it will make life a lot easier on spring 
drools users.

As I see it, a drools RuleBase ~ a hibernate EntityManagerFactory, and a 
drools WorkingMemory ~ a hibernate EntityManager.
So the RuleBaseBean could implement DisposableBean (and other lifecycle 
interfaces as needed) so it knows when to destroy the rulebase (if 
that's needed)?

Seam also does something similar, but only on the working memory:
http://docs.jboss.com/seam/2.0.1.GA/api/org/jboss/seam/drools/ManagedWorkingMemory.html
Notice the destroy() method.

With kind regards,
Geoffrey De Smet
