any comment?

in fact, i want a service to have a interface containing business logic methods, and another interface containing lifecycle management methods(such as start/restart/stop).

because i don't want the business logic interface extends lifecycle management interface, so there are two ways (as far as i know) to go:

1) implements business logic interface only, other methods will be called via reflection. (but some problems may occure, such as interceptors is useless to lifecycle management methods)

2) change HiveMind, let one service can implement more than one interfaces. (will require changes in more than one java file)

    Summary: The ability to specify multiple interfaces of a service
       Type: Wish

     Status: Open

Description:
(Sorry, because sending email to hivemind-dev-subscribe@jakarta.apache.org can not make me subscribe, so i post it here)

Currently, one service can only have one interface specifiled.

Inside ProxyBuilder.java, the proxy class built only implements this "major" interface. This behavior is coded as such:
    
public ProxyBuilder(String type, ServicePoint point)
{
   ...
   _classFab.addInterface(_serviceInterface);
   ...
}

public void addServiceMethods(String indirection)
{
   ...
   Method[] methods = _serviceInterface.getMethods();
   for (int i = 0; i < methods.length; i++) ...
   ...
}


Because of this behavior, if there is a class:

class ServiceABImpl implements ServiceA, ServiceB

This class will be wrapped inside a proxy class, but the proxy class can only implement one interface, that makes the usage of this class/service inconvienent.

So, there is a wish, wish that more than one interfaces can be specified to one service.
