Hi,
I'm trying to use shared object implementation of the ECF framework
and I'm experiencing problems. I wrote some code largely inspired by
the test cases and from
http://wiki.eclipse.org/Sharing_objects_over_XMPP.
This is my source code, I start to define some class variables :
public static final String CHAT_ROOM_NAME = "chatroom";
public IContainer[] clients = new IContainer[2];
IChatRoomContainer[] chatRoomContainer = new IChatRoomContainer[2];;
protected String[] usernames = {"user1@domain", "user2@domain"};
protected String[] passwords = {"pwd", "pwd"};
And then I connect my two clients to the server and also I connect
them to the chatroom. I can browse participants, send chat messages
with no problems. Here is the code, I think it is OK :
System.out.println("> Creation client 0");
clients[0] =
ContainerFactory.getDefault().createContainer("ecf.xmpp.smack");
ID id0 =
IDFactory.getDefault().createID(clients[0].getConnectNamespace(),
usernames[0]); IConnectContext connectContext0 =
ConnectContextFactory.createUsernamePasswordConnectContext(usernames[0],
passwords[0]);
clients[0].connect(id0, connectContext0);
System.out.println("> Get chatRoom 0");
final IChatRoomInfo info0 =
((IPresenceContainerAdapter)clients[0].getAdapter(IPresenceContainerAdapter.class)).getChatRoomManager().getChatRoomInfo(CHAT_ROOM_NAME);
if (info0 == null)
throw new Exception(NLS.bind("no chat room {0} avalable",
CHAT_ROOM_NAME));
chatRoomContainer[0] = info0.createChatRoomContainer();
System.out.println("> Connect to chatRoomContainer 0");
chatRoomContainer[0].connect(info0.getRoomID(), null);
System.out.println("> Creation client 1");
clients[1] =
ContainerFactory.getDefault().createContainer("ecf.xmpp.smack");
ID id1 =
IDFactory.getDefault().createID(clients[1].getConnectNamespace(),
usernames[1]); IConnectContext connectContext1 =
ConnectContextFactory.createUsernamePasswordConnectContext(usernames[1],
passwords[1]);
clients[1].connect(id1, connectContext1);
System.out.println("> Get chatRoom 1");
final IChatRoomInfo info1 =
((IPresenceContainerAdapter)clients[1].getAdapter(IPresenceContainerAdapter.class)).getChatRoomManager().getChatRoomInfo(CHAT_ROOM_NAME);
if (info1 == null)
throw new Exception(NLS.bind("no chat room {0} avalable",
CHAT_ROOM_NAME));
chatRoomContainer[1] = info1.createChatRoomContainer();
System.out.println("> Connect to chatRoomContainer 1");
chatRoomContainer[1].connect(info1.getRoomID(), null);
At this point, I tried to share an object by the client 0. All seems
fine, the client 0 can access the object and I can see its presence
when I call the getSharedObjectIDs() of the ISharedObjectManager.
final ISharedObjectContainer socontainer0 =
(ISharedObjectContainer)chatRoomContainer[0].getAdapter(ISharedObjectContainer.class);
final ISharedObjectManager manager0 =
socontainer0.getSharedObjectManager();
System.out.println("> Creation manager");
if (manager0 == null) throw new Exception("manager is null");
final ID objectID = IDFactory.getDefault().createStringID("xxx");
System.out.println("> Add shared object");
MySharedObject shared = new MySharedObject(objectID.getName());
final ID id = manager0.addSharedObject(objectID, shared, null);
System.out.println("> We sleep a litle time...");
Thread.sleep(4000);
System.out.println("> Client 0 retrieve so");
final MySharedObject sharedObject0 =
(MySharedObject)manager0.getSharedObject(id);
if (sharedObject0 == null) throw new
Exception("sharedObject is null");
System.out.println("OK");
Then I try to use the shared object with my client 1 which is also
connected to the chatroom. Unfortunately the sharedObject1 is always
'null'. When I call the getSharedObjectIDs() of the
ISharedObjectManager, the object is not present.
System.out.println("> Client 1 retrieve so");
final ISharedObjectContainer socontainer1 =
(ISharedObjectContainer)chatRoomContainer[1].getAdapter(ISharedObjectContainer.class);
MySharedObject sharedObject1 =
(MySharedObject)socontainer1.getSharedObjectManager().getSharedObject(id);
if (sharedObject1 == null)
{
System.out.println("Cannot retrieve sharedObject1");
throw new Exception("sharedObject1 is null");
}
System.out.println("OK");
sharedObject1.getMyName();
I try to call explicitly
MySharedObject.this.replicateToRemoteContainers but this does not seem
have an effect.
I tried this source code with :
- ECF 1.2.0 on Eclipse 3.3.1.1
- ECF 2.0 on Eclipse 3.4
I also tried on server :
- ejabberd 1.1.26
- openfire 3.4.4
Is there a problem in the source code ? Does the jabber server needs a
special configuration ? I don't know where the problem comes from.
Could you help me ?
Thanks a lot,
Cyril
