@ManagedBean inside OSGi bundle in GlassFish (3.1)

Was struggling getting a @ManagedBean to be able compile correctly under GlassFish - needed to add the following packages to the Import-Package entry of the Manifest:

com.sun.ejb.containers,com.sun.ejb.spi.io

This allowed us to have a ManagedBean in the bundle.

For example - want to have a @Singleton class for some processing.

@Singleton
public class TestSingleton {
    public String testMySingleton() {
        return "This is a test from my singleton!";
    }
}

(this would be a javax.annotation.ManagedBean, not a Faces ManagedBean):

@ManagedBean
public class SingBean {
    @EJB
    private TestSingleton testSingleton;

and for testing purposes - within the MDB:

@MessageDriven(mappedName = "jms/MyQueue", activationConfig = {
    @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue")
})
public class ExtIncMDB {
    @Resource
    SingBean myBean;
