Using CDI in OSGi Bundles?
Hi Everyone,
I am trying to use CDI inside my OSGi bundles and I'm stuck. I am trying to use simple @Inject in my code (not @Publish, @OSGiService provided by Weld-OSGi). I have a very simple class ATM with one attribute Transport. Transport have 2 implementations SoapAtmTransport and StandardAtmTransport (@Default). My ATM class is as follows.
public class AutomatedTellerMachine {
@Inject
private ATMTransport transport;
public void deposit(BigDecimal bd) {
System.out.println("deposit called");
transport.communicateWithBank(null);
}
public void withdraw(BigDecimal bd) {
System.out.println("withdraw called");
transport.communicateWithBank(null);
}
public ATMTransport getTransport() {
return transport;
}
public void setTransport( ATMTransport transport) {
this.transport = transport;
}
}
I am calling this class from my Activator.
Below is my MANIFEST.mf
Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: ATMBundle Bundle-SymbolicName: ATMBundle Bundle-Version: 1.0.0.qualifier Bundle-Activator: com.ctl.test.ATMActivator Import-Package: org.osgi.framework;version="1.3.0", javax.inject,javax.enterprise.inject Bundle-RequiredExecutionEnvironment: JavaSE-1.6
I have added the following lines to the standalone.xml
<property name="org.osgi.framework.system.packages.extra"> javax.inject,javax.enterprise.inject </property>
But when I try to deploy my bundle I'm getting following error.
20:27:55,612 INFO [org.jboss.as.server.deployment] (MSC service thread 1-4) JBAS015877: Stopped deployment ATMBundle.jar in 13ms

I have heard there is something called Weld-OSGi. But I couldn't find any resource which can help me to get this thing started.
I'm attaching my project here along with source. Could some one please help me out onm this?
