Hi Soniya, I don't know how Blueprint and Spring-DM interact. Blueprint was a standardization of Spring-DM and so I would not expect them to be used together as you have show. Spring bean processing is unlikely to understand how to handle the reference-list because they're two parallel approach to the same problem. You might want to try asking on the Gemini-Blueprint list for suggestions. In the absence of that you could just use Blueprint to achieve what you have shown (i.e. use Blueprint beans instead of Spring beans in your xml), unless there a Spring specifics that you require.

Sent by: [email protected] Thanks for the reply. I tried to use <reference-list>. But since I use spring dm I had to merge both spring and blueprint. My config file is , <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:beans="http://www.springframework.org/schema/beans"; xmlns:osgi="http://www.springframework.org/schema/osgi"; xmlns:util="http://www.springframework.org/schema/util"; xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/osgi http://www.springframework.org/schema/osgi/spring-osgi.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd";> <beans:bean name="remoteManager" class= "com.myapp.platform.remote.RemoteManager" init-method="start"> <beans:property name="services"> <reference-list id="serviceReferenceList" interface= "com.myapp.serviceprovider.IRemoteServiceProvider" member-type= "service-object" /> </beans> </beans:bean> </blueprint> This gives an error : The matching wildcard is strict, but no declaration can be found for element 'reference-list'. If I place the <reference-list> outside the <beans:bean> then I do not get any error but then the "services" property does not get refreshed even if the reference-list "serviceReferenceList" is updated. Also note that the reference-list declaration works only if the default namsespace is blueprint.

No. You should just handle the dynamics. <reference-list> is updated as the services change. -- BJ Hargrave Senior Technical Staff Member, IBM OSGi Fellow and CTO of the OSGi Alliance [email protected] office: +1 386 848 1781 mobile: +1 386 848 3788 From: Soniya Chavan <[email protected]> To: OSGi Developer Mail List <[email protected]> Date: 2013/09/03 08:54 Subject: Re: [osgi-dev] How to delay initialization of osgi:list ? Sent by: [email protected] Correct. So is refresh bundle (bundle which has the list declaration) a good option?

Assuming that many bundles could register IRemoteServiceProvider services, how could Blueprint know when all of them have been registered? Some of these bundles may not have even been started yet. -- BJ Hargrave Senior Technical Staff Member, IBM OSGi Fellow and CTO of the OSGi Alliance [email protected] office: +1 386 848 1781 mobile: +1 386 848 3788 From: Soniya Chavan <[email protected]> To: OSGi Developer Mail List <[email protected]> Date: 2013/09/03 06:27 Subject: [osgi-dev] How to delay initialization of osgi:list ? Sent by: [email protected] Hello, How do I make sure that an osgi:list gets initialized after all the beans implementing the interface are initialized.I have a list of services. <osgi:list id="serviceReferenceList" interface= "com.myapp.serviceprovider.IRemoteServiceProvider" member-type= "service-object"/> Now this list should only be initialized when all the classes/beans implementing IRemoteServiceProvider interface are initialized. The problem that I am facing is that this osgi:list gets initialized before my bean implementing the IRemoteServiceProvider interface gets initialized and hence does not get set to the osgi list. Please help. Thanks Soniya DISCLAIMER ========== This e-mail may contain privileged and confidential information which is the property of Persistent Systems Ltd.
