[news.eclipse.technology.ecf] org.eclipse.ecf.example.collab problems

[Li-Te <li-te_cheng@xxxxxxxxxx>]

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.handleAccept(TCPServerSOContainerGroup.java:104)
	at org.eclipse.ecf.provider.comm.tcp.Server$2.run(Server.java:79)
	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

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,
