[jboss-user] Mysql - Wrong driver class for this connection URL

Hi I am quite new to JBoss and I am struggling to get a MySQL Datasource working. I am writing a Seam application but the problem seems to be a JBoss problem and I have tried for several hours to get it woking... I really don't understand what is wrong and I don't know if JMX allows to test the database connection either... I have copied mysql-connector-java-5.1.7-bin.jar to server/default/lib and my datasource is defined as followed: (the driver works when I connect to the database from Eclipse...) <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE datasources PUBLIC "-//JBoss//DTD JBOSS JCA Config 1.5//EN" "http://www.jboss.org/j2ee/dtd/jboss-ds_1_5.dtd"> <datasources> <local-tx-datasource> <jndi-name>MyDatabaseDatasource</jndi-name> <connection-url>jbdc:mysql://localhost:3306/mydatabase</connection-url> <driver-class>com.mysql.jdbc.Driver</driver-class> <user-name>xxx</user-name> <password>xxx</password> <exception-sorter-class-name> org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter </exception-sorter-class-name> <metadata> <type-mapping>mySQL</type-mapping> </metadata> </local-tx-datasource> </datasources> Here is the exception I get... 16:59:10,223 WARN [JBossManagedConnectionPool] Throwable while attempting to get a new connection: null org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Wrong driver class for this connection URL) at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.getLocalManagedConnection(LocalManagedConnectionFactory.java:225) at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.createManagedConnection(LocalManagedConnectionFactory.java:195) at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.createConnectionEventListener(InternalManagedConnectionPool.java:611) .... 16:59:10,231 WARN [JDBCExceptionReporter] SQL Error: 0, SQLState: null 16:59:10,231 ERROR [JDBCExceptionReporter] Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Wrong driver class for this connection URL); - nested throwable: (org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Wrong driver class for this connection URL)) Many thanks for your help Oscar
