Thank you for the reply Peter.
Extremely sorry if I could not explain this properly. But this is not an issue 
in either Spring or OSGi. We need another way to declare the OSGi services so 
that they can be accessed remotely.

Thanks

HttpInvoker

Are you sure this is not a Spring problem? It is at least not described in a 
way that I can recognize it as an OSGi problem, there such problems are quite 
straightforward to solve with OSGi services.

Kind regards,

Hi All,

We are facing the below problem when declaring OSGi using Spring HttpInvoker. 
Really appreciate if I can get any help.

Our application uses OSGi and Spring httpInvoker for remote calls being made to 
the OSGi services.The bundles are grouped into 3 levels Platform, ApplicationA 
and ApplicationB. Both the Application level bundles depend on Platform bundles 
but are independent of each other. The requirement is to deploy these 
applications together as well as independently.

There are 3 services:
1.      Platform level service (Required for both Applications)
2.      Application A level service
3.      Application B level service

A section of the xml file from Platform bundle is given below. We cannot add 
the references to the Application A or B service in the platform bundle since 
the platform level bundle should be independent of the Application bundles. 
There cannot be two xml files with the service declarations since both these 
applications need to be deployed together. Is there an alternative way to 
declare these services in the Application bundles?

<bean id="platformService" 
class="com.platform.service.impl.PlatformService"></bean>
<bean id="applicationAService" 
class="com.appA.service.impl.ApplicationAService"></bean>
<bean id="applicationBService" 
class="com.appB.service.impl.ApplicationBService"></bean>

<bean name="platformServiceExporter"    
class="org.springframework.remoting.httpinvoker.SimpleHttpInvokerServiceExporter"
<property name="service" ref="platformService"/>
      <property name="serviceInterface" 
value="com.platform.service.IPlatformService"/>
</bean>

<bean name="applicationAServiceExporter"    
class="org.springframework.remoting.httpinvoker.SimpleHttpInvokerServiceExporter"
<property name="service" ref="applicationAService"/>
      <property name="serviceInterface" 
value="com.appA.service.IApplicationAService"/>
</bean>

<bean name="applicationBServiceExporter"    
class="org.springframework.remoting.httpinvoker.SimpleHttpInvokerServiceExporter"
<property name="service" ref="applicationBService"/>
      <property name="serviceInterface" 
value="com.appB.service.IApplicationBService"/>
</bean>


<bean id="httpServer" 
class="org.springframework.remoting.support.SimpleHttpServerFactoryBean">
      <property name="contexts">
<util:map>
<entry key="/remoting/PlatformService" value-ref="platformServiceExporter"/>
<entry key="/remoting/ApplicationAService" 
value-ref="applicationAServiceExporter"/>
<entry key="/remoting/ApplicationBService" 
value-ref="applicationBServiceExporter"/>
            </util:map>
      </property>
<property name="port" value="8080" />
</bean>

Thanks
