Hi All,
Please see my setup and code.
Version: apache-karaf-3.0.5
*Part 1*: Service class
Service:
------------
package org.jrb.test;
public interface MyService {
public String echo(String message);
}
package org.jrb.test;
public class MyServiceImpl implements MyService {
public String echo(String message) {
return "Echo processed: " + message;
}
}
Blueprit:
------------
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
default-activation="lazy">
<bean id="serviceBean" class="org.jrb.test.MyServiceImpl"/>
<service id="MyService" ref="serviceBean"
interface="org.jrb.test.MyService"/>
</blueprint>
i can see my service in list:
------------------------------------------
onos> service:list | grep serviceBean
*osgi.service.blueprint.compname = serviceBean*
*Part 2*: consumer class for testing
Blueprint
-------------
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
default-activation="lazy">
<reference id="MyService" interface="org.jrb.test.MyService"/>
<bean id="b" class="org.ct.command.AddCommand" activation="eager" >
<property name="serviceBn" ref="MyService" />
</bean>
<command-bundle xmlns="http://karaf.apache.org/xmlns/shell/v1.1.0";>
<command>
<action class="org.ct.command.AddCommand"/>
</command>
</command-bundle>
</blueprint>
In Java:
------------
package org.ct.command;
import org.apache.felix.gogo.commands.Action;
import org.apache.felix.gogo.commands.Argument;
import org.apache.felix.gogo.commands.Command;
import org.apache.felix.service.command.CommandSession;
import org.jrb.test.MyService;
@Command(scope = "onos", name = "service-add", description = "Adds a
Client")
public class AddCommand implements Action {
public AddCommand()
{
}
private MyService serviceBn;
public void setServiceBn(MyService serviceBn)
{
this.serviceBn = serviceBn;
}
public MyService getServiceBn() {
return service;
}
@Override
public Object execute(CommandSession session) throws Exception {
System.out.println("Executing command add");
if(serviceBn != null)
System.out.println("serviceBn is not null");
else
System.out.println("serviceBn is null !!");
if(serviceBn != null)
System.out.println(serviceBn.echo("testing....."));
}
}
In the above code, if i run the command "service-add", my serviceBn is
always NULL. The reference is not injecting the bean.
Is there anything missing in my code? please help.
Regards,
Jayanth
