I would not have thought that it is possible to combine Aries Blueprint
and spring namespaces.
All the better that it seems to work :-)
How do you solve the classloader problem? Does the blueprint approach
still have the same issues as spring dm? So does the user still
have to make sure all internals the namespace needs are imported?

I've just committed a new module (and the additional required changes and

blueprint.
See the source code at
http://svn.apache.org/viewvc/aries/trunk/blueprint/blueprint-spring/src/main/java/org/apache/aries/blueprint/spring/
It's limited and not much tested for now, but it can handle things like the
following:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:bp="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:bean="http://camel.apache.org/schema/blueprint";
xmlns:util="http://www.springframework.org/schema/util";
xsi:schemaLocation="
http://www.osgi.org/xmlns/blueprint/v1.0.0

<!-- plain blueprint bean referencing a spring bean -->
<bean id="artemis" class="org.apache.camel.component.jms.JmsComponent">
<property name="connectionFactory" ref="jmsConnectionFactory"/>
</bean>
<!-- spring bean -->
<bean name="jmsConnectionFactory"
class="org.apache.activemq.artemis.api.jms.ActiveMQJMSClient"
factory-method="createConnectionFactory" xmlns="
http://www.springframework.org/schema/beans";>
<constructor-arg value="tcp://0.0.0.0:61616?user=karaf&password=karaf"/>
<constructor-arg value="broker"/>
</bean>
<!-- spring bean using custom namespace, referencing spring and
blueprint beans -->
<util:list id="springList" xmlns="
http://www.springframework.org/schema/beans";>
<value>foo</value>
<ref bean="jmsConnectionFactory" />
<ref bean="artemis"/>
</util:list>
<!-- blueprint service referencing a spring bean -->
<service ref="springList" auto-export="all-classes"/>
</blueprint>
So you can use the default spring namespace or custom spring namespaces and
cross-reference beans between blueprint and spring.
I haven't tried auto-wiring or any advanced usage such as AOP.
I'll try to commit a few initial integration tests beginning of next week.
Please have a look and provide feedback and additional use cases (as tests
?).
Cheers,
