i know there are already a few threads about this error, but none of them solved my problem.

i built a standalone server and client (without eclipse, launch-files or something else, just by calling the server/client class) based on examples by Eike Stepper:
- server: http://git.eclipse.org/c/cdo/cdo.git/tree/plugins/org.eclipse.emf.cdo.examples/src/org/eclipse/emf/cdo/examples/server/Server.java
- client: http://git.eclipse.org/c/cdo/cdo.git/tree/plugins/org.eclipse.emf.cdo.examples/src/org/eclipse/emf/cdo/examples/StandaloneManualExample.java

i attached a picture with my included plugins (for the server). i already included 'org.eclipse.emf.cdo.server.ocl_4.0.0.v20120911-1146.jar' (as mentioned in other threads) and in the osgi-terminal it is marked as resovled.

i also tested the precompiled server from 'emf-cdo-R20130213-0014-CDOServer-Linux.zip' (also added the ...server.ocl-jar) and i got the same error.


the request of my client which causes the error looks like that:
// the connection is create like in the example above
CDOTransaction transaction = s.openTransaction();
CDOQuery cqo = transaction.createQuery("ocl", "Company.allInstances()");
final List<Company> companies = cqo.getResult(Company.class);
int size = companies.size();


The error trace from the server looks like:
[ERROR] Factory not found: org.eclipse.emf.cdo.server.queryHandlerFactories[ocl]
org.eclipse.net4j.util.container.FactoryNotFoundException: Factory not found: org.eclipse.emf.cdo.server.queryHandlerFactories[ocl]

Has anybody some ideas? Did i miss any dependency or something?

A standalone server needs to register the needed factory via:

OCLQueryHandler.prepareContainer(IPluginContainer.INSTANCE);

Cheers

OCLQueryHandler.prepareContainer(IPluginContainer.INSTANCE);

that and a few more dependencies seem to fix my problem

Thanks Eike
