Hi Andrei,
OK, let me try to summarize.
spring-dm is a spring extension allowing you to use OSGi services in spring.
For instance, you use spring-dm to have <osgi:service/> or
<osgi:reference/> elements.
If you don't need this, you can use spring directly in Karaf (not need
to use blueprint).
If you want to use blueprint <service/> and <reference/> (blueprint is
the specification coming from spring-dm), then, you need blueprint only
(no need to use spring).
A bean can be used in blueprint the same way you do in spring:
<bean id="foo" class="..."/>
So, migrating from spring-dm to blueprint is pretty straight forward
(change namespace and <osgi:*/>).
Now, about the blueprint-spring-extender, it allows you to use some
spring elements in blueprint XML (like <transaction/>, etc).
Regards
JB

I'm trying to upgrade my Karaf 4.0.4 to 4.3.2. In 4.0.4, my bundles are
deployed as spring apps loaded by spring-dm. In karaf 4.3.2 I have no
longer spring-dm. I think the only way to do this, is via blueprint:
Aries or Gemini. But as Aries is the default in Karaf, I would go for Aries.
1. Do you have a specific scenario on how I can start my spring bundles
other then blueprint? Or using blueprint?
2. If I have no other option than to switch to blueprint, do I have to
replace my spring beans with Java beans?
Thanks,
Mura Andrei

I'm not sure I follow what you are trying ;)
It seems you are mixing CamelContext Spring and Blueprint.
If you use Spring CamelContext you don't need blueprint.
If you want to use blueprint (eventually with the extender), you can
use
blueprint namespace.
So, my point is: what namespace do you want to use ? spring or
blueprint ?
