how to Access flow variables in Mule ESB...?

This is my code where I am trying to access a flowvariable named "question"

import org.mule.api.MuleEventContext;
import org.mule.api.MuleMessage;

public class Main {

    public Object onCall(MuleEventContext eventContext) throws Exception {
        MuleMessage msg = eventContext.getMessage();
        msg.getInvocationProperty("Question");
        return msg;                 
    }
}

but I am getting the following error:

Message               : Failed to find entry point for component, the following resolvers tried but failed: [
CallableEntryPointResolver: Object "Main@2cad86ee" does not implement required interface "interface org.mule.api.lifecycle.Callable"

]

Well, the error message is pretty clear:

Object "Main@2cad86ee" does not implement required interface "interface org.mule.api.lifecycle.Callable"

Just implement this interface and life will be peachy.
