Hi, I modified code as you suggested. Removed the activator logic and converted it into simple bean. The bundle when starts it does activate the spring framework which instantiates the beans and does DI. The client bean is now POJO and its instantiated upon bundle start and destroyed on bundle stop. Also the service reference is being set fine.
Now I have question on usage of osgi container like felix. can I use it as middle tier for ejbs like the service bean made available to tomcat instance running outside felix via jndi lookup ?

But as I said you can configure Spring call any method of the ActivatorClient class of yours upon bean factory initialization which would happen once your bundle is activated. And in that call you can perform required invocation Chetan Mehrotra On Tue, May 29, 2012 at 10:36 AM, miten mehta <[email protected]> wrote: Hi, > > >Then how will I invoke the bean ?
