I have a hivemodule.sdl configuration that looks like:
module (id=com.mckesson.adept.net version="1.0.0")
{
service-point (id=ClientController
interface=com.mckesson.adept.net.Controller)
{
invoke-factory (service-id=hivemind.BuilderFactory model=singleton)
{
construct (class=com.mckesson.adept.net.client.ClientController)
{
string { "${com.mckesson.adept.broker.host}" }
int { "${com.mckesson.adept.broker.port}" }
}
}
}
service-point (id=Controller interface=com.mckesson.adept.net.Controller)
{
invoke-factory (service-id=hivemind.BuilderFactory model=singleton)
{
construct
(class=com.mckesson.adept.net.client.ConnectionPoolingController)
{
service { ClientController }
}
}
}
}
When I use the following code:
Controller controller = (Controller) reg.getService(
"com.mckesson.adept.net.ClientController",
Controller.class);
Everything works great.
When I use the following code:
Controller controller = (Controller) reg.getService(
"com.mckesson.adept.net.Controller", Controller.class);
Hivemind gives me the following exception:

Exception in thread "main"
I really don't know why, but I suspect it is because I'm not using the
service element correctly in the contruct element for the BuilderFactory.
Can anybody give me some insight as to what might be wrong?
