Hello!
First to all, thanks for your help 
I'm trying use CDO with a MySQL database. In my cdo-server.xml I have uncommented the lines for it, and my cdo-server.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<cdoServer>
<!--acceptor type="http"/ -->
<acceptor type="tcp" listenAddr="0.0.0.0" port="2036">
<!-- negotiator type="challenge" description="/temp/users.db"/ -->
</acceptor>
<repository name="repo1">
<property name="overrideUUID" value="1ff5d226-b1f0-40fb-aba2-0c31b38c764f"/>
<property name="supportingAudits" value="true"/>
<store type="db">
<mappingStrategy type="horizontal">
<property name="qualifiedNames" value="false"/>
<property name="toManyReferences" value="ONE_TABLE_PER_REFERENCE"/>
<property name="toOneReferences" value="LIKE_ATTRIBUTES"/>
</mappingStrategy>
<dbAdapter name="mysql"/>
<dataSource class="com.mysql.jdbc.jdbc2.optional.MysqlDataSource"
url="jdbc:mysql://localhost/cdoTest"
user="root"/>
</store>
</repository>
</cdoServer>
However, when I try start the server, I always get the follow exception:
!MESSAGE Unknown DB adapter: mysql
!STACK 0
java.lang.IllegalArgumentException: Unknown DB adapter: mysql
at org.eclipse.emf.cdo.server.internal.db.DBStoreFactory.getDBAdapter(DBStoreFactory.java:105)

I have tried using a h2 database, and there is not problem.
Anyone know what is happening with mysql?
Thanks for your help!

Just a note: This property is used with value="" (the empty string) to bypass the automatic UUID generation and use the
repository's name as a UUID instead.

The preceeding two properties are no longer recognized.

That's usually an indication that one of the following statements is true:
1) You're running in OSGi and forgot to deploy the org.eclipse.net4j.db.mysql bundle, *or*
2) Your're running standalone and forgot to IDBAdapter.REGISTRY.put(MYSQLAdapter.NAME, new MYSQLAdapter());
Does this fix the problem?
Cheers

Hi Eike.
This was the problem, I was running the server with a product that used h2, so was not loading org.eclipse.net4j.db.mysql.
I have created my own eclipse product for running the CDO server, including the bundles, and it now running.
Sorry for this clumsy question, the "Unknown DB adapter: mysql" message was confusing me, I was thinking this was a mistake in the configuration file.
Thanks!
