Hi, i am new in the CDO world and i try to get feeling for it and experience.
First i installed the CDO client plugins (with net4j Plugins) in a fresh and updated Eclipse (Eclipse Modelling Tools version).
After this i installed the CDO Source accurately after this instruction:
http://wiki.eclipse.org/CDO_Source_Installation
I started the default "CDOServer" Eclipse Application Configuration and it started without an error. I prepared a simple EMF project with the giving instruction (http://wiki.eclipse.org/Preparing_EMF_Models_for_CDO).
With the first commit, which i do after an other instruction (http://wiki.eclipse.org/Using_the_CDO_User_Interface), i got some exceptions. (Output at the end of this post)
I repeaded the steps of the installation instruction, but i got always the same exceptions.
I looks like a incomplete InputSream. I try to isolate the problem in the last IF-loop of the StoreAccessor->write(). Without this IF-loop the commit works, but i get exceptions if i try to load the commited resource (which i expected).
I have no idea, what is going wrong. I make everything after an instruction a the exceptions give no hints to me.
Have anybody an idea, what the problem is ?
Here is the output, which i get, if i try to commit a resource (without any changes in the source code):

Hi Vincent,
can you indicate which version of CDO, which platform and which DB you
are using?
Thanks,
Stefan

Hi Vincent,

Now you seem to have an additional CDO version from HEAD available.
If you don't ensure that both clients and server are launched from exactly the same set of plugins either version X or HEAD it's likely that you run into trouble. EOFExceptions in protocol signals are an indicator for this situation.
Note that, if you're setting up a development workspace for CDO, you're not expected to install the projects in that workspace as external plugins at the same time!
