IPOJO Component is not exposing service properly

i have ipojo component like

@Component(immediate = true)
@Provides
public class MyComponent implements MyService
{

@Override
    public boolean islock()
    {
        return true;
    }

}

when i deploy in karaf with below command

bundle:install -s mvn:com.my.osgi/mycomponent/0.0.1

if i do service:list at karaf console it shows output like

[org.apache.felix.ipojo.Factory] 
    -------------------------------- 
     component.class = com.my.osgi.mycomponent 
     component.description = factory name="com.my.osgi.mycomponent" 
bundle="77" state="valid" implementation-class="com.my.osgi.mycomponent" 
            requiredhandlers list="[org.apache.felix.ipojo:properties, 
org.apache.felix.ipojo:callback, org.apache.felix.ipojo:provides, 
org.apache.felix.ipojo:architect 
    ure]" 
            missinghandlers list="[]" 
            provides specification="com.my.osgi.mycomponent" 
            inherited interfaces="[com.my.osgi.mycomponent]" 
superclasses="[]" 
     component.providedServiceSpecifications = [com.my.osgi.mycomponent] 
     factory.name = com.my.osgi.mycomponent 
     factory.state = 1 
     service.bundleid = 77 
     service.id = 153 
     service.pid = com.my.osgi.mycomponent 
     service.scope = singleton

But i am expecting like below, 

[com.my.osgi.mycomponent] 
    ----------------------------------------------------- 
    instance.name = mycomponent.3c2c91a5-4c28-46c3-a08e-1470192ef353 
     service.bundleid = 76 
     service.factoryPid = com.my.osgi.mycomponent 
     service.id = 397 
     service.pid = 
com.my.osgi.mycomponent.3c2c91a5-4c28-46c3-a08e-1470192ef353 
     service.scope = bundle

What i am doing wrong? I am building with maven.

EDIT: One observation as this bundle working in one bigger application where when this get deploy logs are

but in my case its only two lines

So what this architecture doing and what got modified?

Solution

  • Just add the @Instantiate annotation on your component class. Alternatively, you can use:
