Hi...
This is probably (hopefully) a newbie question. I have a need for
multiple instances of a service, that codewise are identical but have
different runtime configurations -- names, files accessed, etc. So my
thought was to create a service factory that kicked off as many
instances of the
=...MyImpl
property name=prop1 value=value2/
/instance
/ipojo
At runtime, you will have two instances with different properties. The
service will be published by the two instances.

Clement

Properties props = new Properties();

new MessageQueueImpl(props),
props);

I wound up having to create a factory in bundle.b that's an extension
of a class in bundle.a. The bundle.b subclass would override a method
for providing an instantiation of the desired class. I had to
instantiate the factory in bundle.b and pass it to bundle.a. That
lets bundle.a crank out the
Remote shell, perhaps?

where it's better to consolidate a bunch of bundles into one for
runtime efficiency?

Actually, after a week of playing with it, I find I have something
similar to the ManagedServiceFactory principle.
You're right
If ListenerThread implements Runnable, the way to start it is
ListenerThread listener = new ListenerThread(39000);
new Thread(listener).start();
according to the API:
http://java.sun.com/javase/6/docs/api/java/lang/Thread.html
The start() method only works with extensions of Thread.

One of the ServiceTracker constructors takes a Filter, but not a

Would the main() typically be instantiating the class? If so, since
the class would be instantiated at activation, wouldn't this be
doubling memory?
How about gutting the main() and putting the functionality in a method
that both start() and main() would then call?

My experience with OSGi/Felix is comparatively limited compared to
some, but I think I'm making good use of its fundamental capability:
hot-swapping components.
My app is a framework for hooking a varying number of command
interpreters to a varying number of communication components, thus
I tend to use basic OSGi and the Gogo interface, though one of my
command interpreters emulates Gogo commands, so that I can configure
through Jabber or email if needed. I might expand this to handle
emailing the system bundle jars to install or update.

What you probably want in the long run is a datasource-generating
service, to which you pass the database URI. You can put things in
the properties of the service to indicate whether it's Oracle, mySQL,
MSSQL, etc., so that you can have multiple generating services at the
same time.
