Spring Integration OSGi Bundle Problem
Hi, how do I access spring beans using OSGi?
These are the contents of my bundle/ jar file:
Code:
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
Code:
Manifest-Version: 1.0
Created-By: Apache Maven Bundle Plugin
Bundle-Activator: sample.si.filter.demo.Activator
Import-Package: org.apache.log4j,org.osgi.framework;version="1.3",org.

Build-Jdk: 1.5.0_13
Bundle-ManifestVersion: 2
Bundle-SymbolicName: com.smart.services.sample-si-filter-demo
Tool: Bnd-0.0.357
This is my sample-si-filter-demo.xml
Code:

<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:
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:
Code:
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:
Code:
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!
