Hi,
I'm trying to connect to a CDO server from a standalone main class:
OMPlatform.INSTANCE.setDebugging(true);
OMPlatform.INSTANCE.addLogHandler(PrintLogHandler.CONSOLE);
OMPlatform.INSTANCE.addTraceHandler(PrintTraceHandler.CONSOLE);
final IManagedContainer container = ContainerUtil.createContainer();
Net4jUtil.prepareContainer(container);
TCPUtil.prepareContainer(container);
CDONet4jUtil.prepareContainer(container);
container.activate();
final IConnector connector = Net4jUtil.getConnector(container, "tcp://localhost:2036");
final CDONet4jSessionConfiguration sessionConfiguration = CDONet4jUtil.createNet4jSessionConfiguration();
sessionConfiguration.setConnector(connector);
sessionConfiguration.setRepositoryName("repo");
sessionConfiguration.setCredentialsProvider(new PasswordCredentialsProvider("user", "password".toCharArray()));
final CDOSession session = sessionConfiguration.openNet4jSession();
session.options().setPassiveUpdateEnabled(true);
session.options().setPassiveUpdateMode(PassiveUpdateMode.ADDITIONS);
final CDOTransaction transaction = session.openTransaction();
This code is taken from the CDO standalone example. If I run it from a plugin project using the run as "Java Application" menu it runs fine with my target platform.
I used B3 aggregator to create a maven repository from p2 repositories from my target platform. I then created a maven project referencing the created maven repository and added the following dependencies:
<dependency>
<groupId>org.eclipse.emf</groupId>
<artifactId>org.eclipse.emf.cdo</artifactId>
<version>4.10.0</version>
</dependency>
<dependency>
<groupId>org.eclipse.emf</groupId>
<artifactId>org.eclipse.emf.cdo.common</artifactId>
<version>4.10.0</version>
</dependency>
<dependency>
<groupId>org.eclipse.emf</groupId>
<artifactId>org.eclipse.emf.cdo.net4j</artifactId>
<version>4.3.0</version>
</dependency>
<dependency>

<dependency>

<artifactId>org.eclipse.net4j.util</artifactId>
<version>4.10.0</version>
</dependency>
<dependency>
<groupId>org.eclipse.net4j</groupId>
<artifactId>org.eclipse.net4j.tcp</artifactId>
<version>4.2.1</version>
</dependency>
The code compile, but when I run it using the run as "Java Application" menu I get the following timeout exception:
Exception in thread "main" org.eclipse.net4j.channel.ChannelException: org.eclipse.net4j.util.concurrent.TimeoutRuntimeException: Channel registration timeout after 10000 milliseconds

I also get the same exception if I package the maven project and run it using "java -jar" from the command line.
I have tried to see if ClassNotFoundException were raised in debug but nothing suspicious showed up. I was wondering if someone tried something similar or if someone had an idea of some initialization steps I would have missed for standalone use of CDO ?
