Eclipse version: 3.1.0
ECF version: latest CVS
I'll break this down into each example I've tried to run so far...
ECF Hello Client 1
------------------
After launching this example I get a "Launch Error" dialog window with
the message "Could not launch the configuration. Details are in the log.
Would you like to open it?" I click yes on the dialog and here's what's
in the log:
!ENTRY org.eclipse.osgi 2006-03-01 09:34:11.851

There are many more "!ENTRY" messages that are similar in nature.
To solve this problem I go into the run configuration editor under the
"Plug-ins" tab and select all items under the "External Plug-ins" group
under the "Choose plug-ins and fragments to lunch from the list" list.
Now after launching this example I get a new empty Eclipse application
with a new "ECF" menu with a "ECF Hello World" item under it and after
selecting it I get the following in my first Eclipse application console
window:
org.eclipse.ecf.internal.core.Trace: OFF

ECF Example Collab Client 1
---------------------------
After launching this example I get a "Launcher" dialog window with the
message "Launching failed because the org.eclipse.osgi plug-in is not
included in the configuration you are launching. To fix the problem, go
to the Plug-ins tab of this launch configuration and ensure that the
option selected includes said plug-in."
To solve this problem I go into the run configuration editor under the
"Plug-ins" tab and select the "org.eclipse.osgi (3.1.0)" item under the
"External Plug-ins" group under the "Choose plug-ins and fragments to
lunch from the list" list.
Now after launching this example I get a "Launch Error" dialog window
with the message "Could not launch the configuration. Details are in the
log. Would you like to open it?" I click yes on the dialog and here's
what's in the log:
!ENTRY org.eclipse.osgi 2006-03-01 09:51:37.222

This is the only "!ENTRY" message.

Yes...you need to run an ECF server on localhost:3282. There are
several run configs for running a localhost server as a Java app...the
best one to use is called "ECF Collab Server" and it is under the "Java
Application" area in the Run.../Debug... menu. You should start this
server before connecting.
Note you can also use the "ECF Hello Server" run config...although get
an update from dev.eclipse.org because I just found and fixed a problem
in that run config.
Now, you can also run a server completely outside of Eclipse if you
want...as a java application. There is a startup script called
'startserver.cmd|sh' in the following location:
<eclipseworkspace>/org.eclipse.ecf.server-feature/bin/startserver.cmd
(windows)
or
<eclipseworkspace>/org.eclipse.ecf.server-feature/bin/startserver.sh
(linux/mac)
Running these scripts will start a server with published URL of
ecftcp://localhost:3282/server, which is the one used by default for the
ECF Hello Client.
Note we are working on a number of things to change/improve the
usability of dealing with ECF servers...in particular, using the Equinox
Servlet Incubator project:
http://www.eclipse.org/equinox/incubator/server/embedding_in _a_servlet_container.php
And running ECF servers (like the generic server) as plugins in a tomcat
(e.g.) servlet container. Although not ready yet, you can see this work
in the new org.eclipse.ecf.server plugin...which you can access from CVS
if you like, but it's not yet complete. We're working on it actively
though.

This is surprising. Could you look in the error log and find the stack
trace for this? I'm using jmdns for zeroconf discovery nearly
continuously, and I think some other folks are as well...so

Hmmm. Don't understand this as the CVS code is precisely the source of
0.7.2 build. In any event, let me know if you have more details on the
ExceptionInInitializerError above and we'll track down what's going on.
Thanks,
Scott

Hi Folks,
Fix found, applied, and tested on 3.1 and 3.2M6. See this bug report
https://bugs.eclipse.org/bugs/show_bug.cgi?id=135470
For a copy of the jmdns feature (attached as zip) v0.7.7. I expect to
do an ECF stable build this weekend as well and distribute 0.7.7 stable
at that time. But for those that want it now, please go to the above
bug report, download the attached zip file, and unzip the feature to
your <eclipsehome> directory.
