[CDO] dbAdapter MySQL Problem [message #903355]

Hello!

First to all, thanks for your help Wink

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)

	at org.eclipse.equinox.internal.app.AnyThreadAppLauncher.run(AnyThreadAppLauncher.java:26)
	at java.lang.Thread.run(Thread.java:679)

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! Very Happy
