[CDO] Could not activate TCPClientConnector on CDO Hibernate Client/server example [message #1216712]

Hello,

I recently discovered the CDO project and did like the idea of a emf model repository. I first downloaded the Hibernate Store examples from the git repository (http://git.eclipse.org/gitroot/cdo/cdo.git/). The server in the project org.eclipse.emf.cdo.examples.hibernate.server started without any problems. I only changed the underlying database from hsqldb to an existing mysql database running on my computer in the cdo-server.xml. Tables are created in this database by the server when it is started.

Unfortunately I ran into some trouble when I tried to execute the test cases included in org.eclipse.emf.cdo.examples.hibernate.client. When executing the QuickStartTest or any other test in this project the following exception occures:

org.eclipse.net4j.util.lifecycle.LifecycleException: Could not activate TCPClientConnector[localhost:2.036]
	at org.eclipse.net4j.util.container.ManagedContainer.activateElement(ManagedContainer.java:355)

	at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

No error message is printed by the server when connecting is attempted.

Can someone point out a mistake that I might have made? I am using Eclipse 4.3 and installed the most recent version of the CDO plugin and all required plugins as described at http://wiki.eclipse.org/CDO/Hibernate_Store/Download_and_Install.

Thanks in advance,
Thomas

Hi Thomas,

Can you post a bit more info, like the log of the server start and your
cdo-server.xml file?

Thanks Christophe

Hello Christophe,

I attached the log of the server start and my cdo-server.xml.

Thanks in advance,

From your server log it seems that the Net4j extension is not deployed/started. It should look like:

Time to load bundles: 781
Starting application: 2174
osgi> [INFO] CDO server starting
[INFO] Net4j extension starting
[INFO] Net4j acceptor starting: tcp://0.0.0.0:2036
[INFO] Net4j extension started
[INFO] Repository configuration manager extension starting.
[INFO] Repository configuration manager extension started.
[INFO] Security extension starting
[INFO] Security extension started
[INFO] CDO server started
Application Started: 5791

Please deploy the following bundles, too:

org.eclipse.emf.cdo.server.net4j
org.eclipse.net4j
org.eclipse.net4j.tcp

Cheers
/Eike

I have the exact same issue with the same output. I deployed the plugins you mentioned as well but I still don't get the net4j server started. I also attached the server log and the lunch file. I am using the hibernate server example.

I'll really appreciate your help.

Thanks,
Roza

Your server.log clearly indicates that org.eclipse.emf.cdo.server.net4j is not deployed/started.

I'm a little confused by the existance of two different launches:

/org.eclipse.emf.cdo.tests.hibernate/HibernateServer.launch
/org.eclipse.emf.cdo.examples.hibernate.server/CDOHibernateServer.launch

The example plugin seems to have subtle dependencies on the test project, which doesn't seem right.
I've cc'ed Martin who developed the Hibernate store and examples to comment on this and possibly fix it.

Cheers

That is true I was deploying org.eclipse.emf.cdo.net4j in stead of org.eclipse.emf.cdo.server.net4j. My bad. Thanks for your help.
