CDO/Hibernate Store/Quick Start
The quick start of the CDO Hibernate Store takes you through the following steps:
- download and install
- download example projects from cvs
- start the CDO Server
- run client side junit tests to see interaction between the client and server
Download and install
Download the required software:
- Eclipse 3.6 (Helios), as Eclipse 3.6 is in development try the development tab
- EMF 2.6, is normally included with the java EE version of Eclipse
- CDO Nightly build, click on Nxyz (where xyz is a date) to open the nightly build location. The easiest is to download the all features and plugins zip: emf-cdo-AllFeaturesAndPlugins-N201001181004.zip (with a different date in your case ofcourse)
- Teneo 1.2.0, Teneo 1.2.0 can be found a little down on the page
- Hibernate 3.3.2 or later and JDBC drivers, pick the latest ThirdPartyDrivers zip file
Install Eclipse and the plugins, see: Eclipse p2 getting started.
Download the example projects from cvs
After installing Eclipse and the plugins, start Eclipse and in a workspace import/download the following three projects from CVS:
- org.eclipse.emf.cdo.examples.company: contains the example model which has already been prepared for CDO (see here how this is done)
- org.eclipse.emf.cdo.examples.hibernate.server: contains the server configuration and server launch config
- org.eclipse.emf.cdo.examples.hibernate.client: shows client connection code and contains junit tests creating and querying for data
The cvs location of these projects is:
Start the CDO server
To start the CDO server open the org.eclipse.emf.cdo.examples.hibernate.server project and right-click on the CDOHibernateServer.launch and then: Run As > CDOHibernateServer.
Check the console view, after 5-10 seconds you should see:
main [debug.lifecycle.dump] DUMP TCPAcceptor@20 Acceptor.config = TransportConfig[receiveExecutor=java.util.concurrent.ThreadPoolExecutor@46f93, bufferProvider=BufferPool[4,096], protocolProvider=org.eclipse.net4j.ContainerProtocolProvider$Server@139358c, negotiator=null] Acceptor.connectorListener = org.eclipse.spi.net4j.Acceptor$1@ea9bc8 Acceptor.acceptedConnectors = selector = TCPSelector startSynchronously = true synchronousStartTimeout = 20000 serverSocketChannel = sun.nio.ch.ServerSocketChannelImpl[/0.0.0.0:2036] address = 0.0.0.0 port = 2036 [INFO] Net4j extension started [INFO] CDO server started Application Started: 8521
As a default the CDO Hibernate server uses hsqldb.
For your info, the CDO server uses the config file: cdo-server.xml in the config directory in the org.eclipse.emf.cdo.examples.hibernate.server project.
Run client side code
As a last step run some client side code to see the CDO server storing and retrieving data. Open the org.eclipse.emf.cdo.examples.server.hibernate.client project, go to the junit classes in the src directory:
- QuickStartTest: a very simple test which creates one resource and stores a new address in it
- HibernateQueryTest: extensive test which creates a complete test data set and then show various HQL queries.
do right click on one of these two classes and then: Run As > Junit Test.
