Spring Integration OSGi Bundle Problem

[racumin]

Hi, how do I access spring beans using OSGi?

These are the contents of my bundle/ jar file:

sample-si-filter-demo.jar
    -META-INF/
        -spring/
            -sample-si-filter-demo.xml
        -MANIFEST.MF
    -sample/
        -si/
            -filter/
                -demo/
                    -Activator.class
                    -ErrorHandler.class
                    -Filter1.class
                    -Filter2.class
                    -Sender.class
                    -Service.class
                    -Tester.class

This is my MANIFEST.MF

This is my sample-si-filter-demo.xml

<beans xmlns="http://www.springframework.org/schema/beans"

	<si:publish-subscribe-channel id="requests"/>
	<si:filter 
	id="filter1" 
	ref="filter1Bean"

	output-channel="filter1Output"
	discard-channel="discarded"/>
		
	<si:channel id="filter1Output"/>
	<si:service-activator input-channel="filter1Output" ref="serviceBean" method="callService">
	</si:service-activator>
	
	<si:channel id="discarded"/>
	<si:service-activator input-channel="discarded" ref="errorBean" method="errorCaught">
	</si:service-activator>
	
	<bean id="filter1Bean" class="sample.si.filter.demo.Filter1"/>
	<bean id="serviceBean" class="sample.si.filter.demo.Service"/>
	<bean id="errorBean" class="sample.si.filter.demo.ErrorHandler"/>
</beans>

I want my Activator.java to access the "Sender" bean and call the send method (inside start(BundleContext ctx) method) but I do not know how. I tried to print all the service references using this code:

public void start(BundleContext ctx) throws Exception {
	ServiceReference[] srs = ctx.getBundle().getRegisteredServices();
	for (ServiceReference reference: srs) {
		log.info("SVC_REFERENCE: " + reference.toString() + " " + reference.getBundle().getSymbolicName());
	}
}

The output is:

2010-11-18 16:01:25,331 INFO  [Activator] SVC_REFERENCE: [org.osgi.service.packageadmin.PackageAdmin] org.apache.felix.framework
2010-11-18 16:01:25,332 INFO  [Activator] SVC_REFERENCE: [] org.apache.felix.framework
2010-11-18 16:01:25,332 INFO  [Activator] SVC_REFERENCE: [] org.apache.felix.framework
2010-11-18 16:01:25,332 INFO  [Activator] SVC_REFERENCE: [org.osgi.service.startlevel.StartLevel] org.apache.felix.framework

As you can see, there was no ApplicationContext or Sender bean that was registered. How do I do that?

By the way, I am using these bundles:

com.springsource.org.aopalliance-1.0.0.jar   org.springframework.core-2.5.6.SEC01.jar
org.springframework.aop-2.5.6.SEC01.jar      org.springframework.integration-1.0.4.RELEASE.jar
org.springframework.beans-2.5.6.SEC01.jar    org.springframework.transaction-2.5.6.SEC01.jar
org.springframework.context-2.5.6.SEC01.jar  sample-si-filter-demo-1.0.0-SNAPSHOT.jar

And I am using Felix as my osgi container.
Thanks!
