Oh, I'm hanging out on IRC if you want to pop in and say hello (server:
irc.freenode.net, channel #geronimo). I'd love to give you an overview
on how to adapt a protocol for use in OpenEJB and the architecture for
network services. There is plenty of work to be done there.

To all, most likely Alan,
A little confusion on my end. I was trying to use the
ReferenceCollectionListern to handle adding and removing of
EJBContainers. Originally I was thinking of uisng the ContainerIndex
like the EJBServer does. I have a GBean with the following:
1. I suppose the kernel creates a collection of containers during
server startup and passes them to my gbean.
2. During runtime as ejbs are deployed (started) the kernel will end
up calling memberAdded. (Likewise with the stop/undeploy an ejb with
memberRemoved)
public static final GBeanInfo GBEAN_INFO;
static {
GBeanInfoBuilder infoFactory = new
GBeanInfoBuilder(RmiIiopServerGBean.class);
infoFactory.addInterface(SocketService.class);
infoFactory.addAttribute("classLoader", ClassLoader.class,
false);
infoFactory.addAttribute("args", ArrayList.class, true);
infoFactory.addAttribute("props", Properties.class, true);
infoFactory.addAttribute("ip", String.class, true);
infoFactory.addAttribute("port", int.class, true);
infoFactory.addReference("AdapterManager",
AdapterManager.class);
infoFactory.addReference("Containers", EJBContainer.class); //
Use this?
infoFactory.addReference("ContainerIndex",
ContainerIndex.class); // or Use this?
infoFactory.setConstructor(new String[]{"classLoader",
"AdapterManager", "ContainerIndex"});
GBEAN_INFO = infoFactory.getBeanInfo();
}
public static GBeanInfo getGBeanInfo() {
return GBEAN_INFO;
}
public void memberAdded(ReferenceCollectionEvent event) {
EJBContainer container = (EJBContainer) event.getMember();
// TODO: How does this method differ from setContainers()???
log.debug( "RmiIiopServerGBean.memberAdded(): container = " +
container );
log.debug( "RmiIiopServerGBean.memberAdded(): containerID = " +
container.getContainerID() );
............
}
public void memberRemoved(ReferenceCollectionEvent event) {
EJBContainer container = (EJBContainer) event.getMember();
log.debug( "RmiIiopServerGBean.memberRemoved(): container = " +
container );
log.debug( "RmiIiopServerGBean.memberRemoved(): containerID = "
+ container.getContainerID() );
...........
}
public void setContainers(Collection containers) {
log.debug( "RmiIiopServerGBean.setContainers(): containers = "
+ containers );
ReferenceCollection ref = (ReferenceCollection) containers;
ref.addReferenceCollectionListener(this);
this.containers = containers;
}
In my plan, I have:
1. In the reference for Contains, I have a name pattern for EJBs.
However, I don't seem to be able to add a wildcard to represent
any/all containers. I have tried various settings all result in
either a Malformed exception or other.
2. I suspect that I shouldn't use ContainerIndex, but rather
Containers.
3. I have also observed that when using ContainerIndex, the kernel is
able to start my GBean since there is a valid object reference for
ContainerIndex. I have seen messages on the console that indicate
that the kernel is awaiting an object reference for ContainerIndex.
This is probably due to the fact that I don't currently have an ejb
deployed.
