Factory construction is just an alternate way to construct a singleton | <bean> | <constructor factroyClass="x.y.z.A" factoryMethod="create"/> | A bean factory creates an object that implements BeanFactory on which you can call create() to create as many instances as you like: | <beanfactory name="MyFactory"> | ... | | public class MyClass | { | @Inject("MyFactory") | public void setFactory(BeanFactory factory) {} | | public void doStuff() | { | Object one = factory.create(); | Object two = factory.create(); | } | } | The main usecase of beanfactory so far has been to do dependency injection into aop's advices. http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/projects/microcontaine...
