Singleton Service in weblogic cluster is registering but not invoking activate method - weblogic

Question

I am implementing a singleton service in a weblogic 12.2.1.2 with EBJ 3.1 in a maven multimodule EAR project.
My singleton service is registering in the cluster.
This is the log from the node where is registered:
<BEA-000189> <The Singleton Service Appscoped_Singleton_Service is now active on this server.>
And this is from other node:
<BEA-003130> <Appscoped_Singleton_Service successfully activated on server iss3.>
The singleton service is implementing the interface weblogic.cluster.singleton.SingletonService but the methods activate and deactivate is not invoked when the nodes starts or shutdown.
I was reading something about versioned EARs and MANIFEST files but not understood this.
I need some help to make methods activate and deactivate be invoked.
This is my class:
import java.io.Serializable;
import javax.inject.Inject;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.test.MyTimerLocal;
import weblogic.cluster.singleton.SingletonService;
public class MySingletonServiceClass implements SingletonService, Serializable, MySingletonServiceInterface {
private static final long serialVersionUID = 3966807367110330202L;
private static final String jndiName = "MySingletonServiceClass";
private int myValue;
#Inject
private MyTimerLocal myTimer;
#Override
public int getMyValue() {
return this.myValue;
}
#Override
public synchronized void setMyValue(final int myValue) {
this.myValue = myValue;
}
#Override
public void activate() {
System.out.println("activate triggered");
Context ic = null;
try {
ic = new InitialContext();
ic.bind(MySingletonServiceClass.jndiName, this);
System.out.println("Object now bound in JNDI at " + MySingletonServiceClass.jndiName);
this.myValue = 5;
final String msg = "###################### MySingletonServiceClass.activate():: Fechamento agendado para " + this.myTimer.agendaExecucao() + " ###############";
System.out.println(msg);
} catch (final NamingException e) {
this.myValue = -1;
e.printStackTrace();
} finally {
try {
if (ic != null) {
ic.close();
}
} catch (final NamingException e) {
e.printStackTrace();
}
}
}
#Override
public void deactivate() {
System.out.println("deactivate triggered");
Context ic = null;
try {
ic = new InitialContext();
ic.unbind(MySingletonServiceClass.jndiName);
System.out.println("Context unbound successfully");
} catch (final NamingException e) {
e.printStackTrace();
}
}
}
Thanks for your time.

I got this working now with this in my src\main\application\META-INF\weblogic-application.xml
<wls:singleton-service>
<wls:class-name>com.test.MySingletonServiceClass</wls:class-name>
<wls:name>Appscoped_Singleton_Service</wls:name>
</wls:singleton-service>
