Hi,
I was trying out the sample ECF app in org.eclipse.ecf.example.collab
and ran into a two problems - the first I was able to resolve.
Background: I obtained the code via CVS, ran server and 2 clients using
a single WinXP machine using localhost and JDK 5.0, and used the sample
launch configurations (ECF Collab Server, Client 1, and Client 2) as
suggested in http://www.eclipse.org/ecf/downloads.html :
a) localhost:3282/server vs localhost:3282//server
I run Client 1, and use "ECF/Join Test Collaboraton (localhost)".
Then I run Client 2 and use the menu, "ECF/Join Test Collaboration
(localhost)", it logs me on with same userid as Client 1.
So I quit and restarted Client 2, but used "ECF/Join Client
Collaboration..." instead, bringing up the dialog. I change the
nickname and hit "Finish".
I get "Could not connect to group 'ecftcp://localhost:3282/server'. I
also see a stacktrace:
java.io.InvalidObjectException: Container for target /server not found!
at
org.eclipse.ecf.provider.generic.TCPServerSOContainerGroup.h andleAccept(TCPServerSOContainerGroup.java:104)
at org.eclipse.ecf.provider.comm.tcp.Server$2.run(Server.java:7 9)
at java.lang.Thread.run(Thread.java:595)
I notice that "//server" is showing up in the console for the server and
client 1. So I change the Group ID, which was
'ecftcp://localhost:3282/server' to 'ecftcp://localhost:3282//server'
(extra slash).
Now the joinGroup call appears to be successful. There must be a typo
somewhere with an extra slash.
b) ClassNotFoundException: RemoteSharedObjectMsgEvent
Upon connecting 2 clients, immediately I get
trace)org.eclipse.ecf.provider(container)[02/08/05;17:23:40: 435]sendcontainermessage:ContainerMessage[GUID[ST4iAanAkSXKQ rEwKeexHHoKmrY-];null;2;SharedObjectMessage[StringID[chat];R emoteSharedObjectMsgEvent[StringID[chat];null;SharedObjectMs g[null:handleNotifyUserAdded(Li-Te

I continue seeing the same error whenever I try typing in the team chat
area, etc. Whenever I type in client 1, client 2 generates the above
stacktrace, and vice versa (typing in client 2 triggers the stacktrace
in client 1).
It looks like a classloader problem with RemoteSharedObjectMsgEvent,
which is defined in the org.eclipse.ecf.example.collab plugin, whereas
the rest of the ECF Event classes are found in the org.eclipse.ecf plugin.
Any thoughts?
Thanks,
Li-Te
