This isn't really an MC question, it's a programming patterns question :-) The answer is to use a factory/singleton pattern. e.g. These two would use the object constructed by MyFactory (which can also be an instance class rather than the shown static method). | <bean name="Bean1"> | <constructor factoryClass="MyFactory" factoryMethod="getInstance"/> | </bean> | | <bean name="Bean2"> | <constructor factoryClass="MyFactory" factoryMethod="getInstance"/> | </bean> | | ALTERNATIVE: | | If you don't like the boiler plate of coding a singleton factory, | I wrote an aspect that does it for you: | http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/projects/aop/trunk/asp... | which I guess could also be configured with an annotation (although it doesn't exist currently). | | | | <bind pointcut=&quot;execution((a)com.acme.Singleton-&gt;new())&quot;&gt; | | <advice name="constructorAdvice" aspect="Singleton"/> | | </bind> | | | | @com.acme.Singleton | | public class MyBean {} | | | | I'm sure you can adapt it to your needs if it doesn't do exactly what you want. ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4130750#...
