Hi,
I have to maintain a CDOServer installation and it has been a while. I get a new exception, not sure if it is a set of incompatible classes that Kepler updated to.
I get:
Caused by: java.lang.ClassNotFoundException: org.eclipse.emf.cdo.spi.common.branch.InternalCDOBranchManager$BranchLoader3 cannot be found by org.eclipse.emf.cdo.server_4.4.1.v20150911-1807
at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:501)
I follow this https://wiki.eclipse.org/Setting_up_a_CDO_Server
Here is the list from the product file:
<plugins>
<plugin id="com.instantiations.assist.eclipse.fragment.swt" fragment="true"/>
<plugin id="com.example.cdoserver"/>

<plugin id="org.h2"/>
</plugins>
I see Kepler now has a version org.eclipse.emf.cdo_4.4.1.v20150914-0747 in plugins. Could this cause an issue?
When you leave the CDOServer.product file list of plugins and fragments having no version, does it just use the latest?
How do you identify which plugin has the missing class?
Thx

Hi David,
All CDO plugins in your clients and servers should ideally come from the same build. The class
org.eclipse.emf.cdo.spi.common.branch.InternalCDOBranchManager$BranchLoader3 is in the org.eclipse.emf.cdo.common
plugin, from version 4.4 on:
/**
* @since 4.4
*/
public interface BranchLoader3 extends BranchLoader2
{
public void renameBranch(int branchID, String oldName, String newName);
}
When you leave the CDOServer.product file list of plugins and fragments having no version, p2 uses the latest available
in the configured repos that matches all (other) requirements.
Cheers

Thx,
That seems to be the problem. I see org.eclipse.emf.cdo.common with the correct version 4.4.1 is installed in my Kepler install in the "Eclipse Installation details" plugin dialog. But when I go to the Dependencies, Required Plugins dialog for my project it is not display, but all the other cdo plugins seem to be, it is also not in those already specified. org.eclipse.emf.cdo.common.db is already included, but is version 3.0.301 I did a Clean... but it still does not show up. Not sure how I can get this dialog to show the plugin that is already present in my installation?
EDIT - I deleted all 4.4.1 version CDO related plugins, I reinstalled all 4.2.1 from the Kepler release update site. This solved the problem. It looks like I had a partial update of CDO from when I did a Eclipse update recently.
David

I find it hard to imagine what you're looking at. Can you attach a screenshot?

That plugin is most likely irrelevant. It just contains an (almost) abandoned attempt to provide a DB-based revision
cache. It's version might well be way behind the more actively evoloved plugins.

Maybe the screenshot helps me to see the problem...
