Body:
Allowing the proxy to implement all interfaces of the implementing class is not
a good idea. You should code to the service interface. What you can do in
this situation is this...
public interface ILifecycle
{
public void start();
public void stop();
}
public interface IBusiness
{
public void doSomething();
public void doSomethingElese();
}
public interface IService extends IBusiness, ILifecycle
{
// Add some methods here if you wish.
}
So, in your application you could use the service interface everywhere you
needed to use both your business interface AND your lifecycle interface. Your
business logic need only know about your business interface. This is what I do
using EJBs so that I keep my remote interface in sync with my impl class
without making my impl class implement the remote interface. I introduce a
superinterface that contains the business methods and have my impl class
implement that and have the remote interface extend it.

Key: HIVEMIND-39
Summary: The ability to specify multiple interfaces of a service
Type: Wish
Status: Open
Priority: Minor

Description:
(Sorry, because sending email to [EMAIL PROTECTED] 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.
