| [CDO] 3.0 Standalone server [message #507005] |

Hi,
Can anyone give me a snippet that instantiates a standalone (outside of OSGI) CDO 3.0 server.
I want to use Spring Context to wire the CDO server instance in a J2EE Web application.
I'm also taking advantage of the container lifecycle and using default init and destroy methods for the spring beans:
default-init-method="activate"
default-destroy-method="deactivate"
I've faced problems when trying to move these into the IoC container:
IMappingStrategy mappingStrategy = CDODBUtil.createHorizontalMappingStrategy(true);
IStore store = CDODBUtil.createStore(mappingStrategy, dbAdapter, dbConnectionProvider);
the implementation of createStore() changes the state of the mappingStrategy, and sets the store property of the strategy.
Thanks in advance,
Assen.

There might be examples at
http://wiki.eclipse.org/User_Contributed_CDO_Documentation

That should generally be possible. A (possibly outdated) example is in
the Wiki, see above.

I think you must be careful. Some components are implicitely activated
when they are "contained" in other components. For a repository for
example it should only be necessary to explicitely activate the
repository component itself.

What exactly is the problem? How can I help?

Hi Eike,
the examples from the wiki are CDO 2.0 and outdated.
I'll contribute my updated examples of using standalone spring wired CDO server and client, once I get all the things running. I already have a working client.
I realized that I can't use the Spring's container's default bean activation methods for the CDO server.
Suppose I already have activated a repository, how can I start the configure a container correctly?
I'm using the code below, but I do get an exception when the client opens a session
// Spring wired beans
Map<String, String> props = (Map<String, String>) applicationContext.getBean("props");
IDBAdapter dbAdapter = (IDBAdapter) applicationContext.getBean("dbAdapter");
IDBConnectionProvider dbConnectionProvider = (IDBConnectionProvider) applicationContext.getBean("dbConnectionProvider");
// Repository
IMappingStrategy mappingStrategy = CDODBUtil.createHorizontalMappingStrategy(true);
IStore store = CDODBUtil.createStore(mappingStrategy, dbAdapter, dbConnectionProvider);
final IRepository repository = CDOServerUtil.createRepository("repo1", store, props);
((Repository) repository).activate();
// Further I create the container:
IManagedContainer container = ContainerUtil.createContainer();
Net4jUtil.prepareContainer(container);
TCPUtil.prepareContainer(container);
container.activate();
IAcceptor acceptor = (IAcceptor) container.getElement("org.eclipse.net4j.acceptors", "tcp", null);
((Repository) repository).activate();
while (System.in.read()==-1) {
Thread.sleep(500);
}
((Repository) repository).deactivate();
container.deactivate();
...
When I run the client, I get the following exception:
[ERROR] Factory not found: org.eclipse.net4j.serverProtocols[cdo]
org.eclipse.net4j.util.container.FactoryNotFoundException: Factory not found: org.eclipse.net4j.serverProtocols[cdo]
at org.eclipse.net4j.util.container.ManagedContainer.getFactory (ManagedContainer.java:193)
How can I register this factory manually with the container?
Assen.

Ok, I resolved it, but adding a dependency jar which I have missed, and
container.registerFactory(new CDOServerProtocolFactory(
new IRepositoryProvider() {
@Override
public IRepository getRepository(String name) {
return repository;
}
}));
Further goal is to skip the use of IManagedContainer and use the Spring bean container instead.
Assen.
