Why do you want to use all three? For a new application, one generally chooses EJB 3 or Spring; not both. With legacy code, having a mixture makes sense. But then you would already have an example.

I thought spring is a j2ee framework just like liferay, seam e.t.c that supports ejb technology. It's like choosing between the java language and the java lang api.
Anyways to the OP AppFuse is a good start. It has good quick start tutorials to set you off.

I ran into this thread i find very helpful. Spring and EJB can be used interchangeably. It depends on the project at hand.

Make sure your bean (manager) is registered. From your config file the bean definition code is commented out
Leave out
if you don't need it but you need the other part of the code..

Thanks for reply but my problem in am not able to add my bean to JNDI. It is not getting the bean ref so that jndi tree is made.
And as far as manager which is commented out is simply because it would end up giving multiple declaration for bean manager. How would i add it to jndi. If you want I can add my whole code there.

Correct me if i'm wrong..
[code=java]
<jee:jndi-lookup id="manager" jndi-name="ManagerImpl/remote" lookup-on-startup="true" proxy-interface="oaklabs.ICL.EJB.service.Manager"></jee:jndi-lookup>
[code]
The above code does a jndi lookup AND NOT register bean. You need to register your 'manager' bean by defining it's class name & id.
