[jboss-user] [JBoss Seam] - Problem with database drivers

[haefti]

Hi!
I have a problem with my database connection.
My <project-name>-dev-ds.xml looks like this:

  | <?xml version="1.0" encoding="UTF-8"?>
  | <datasources>
  |    <local-tx-datasource>
  |       <jndi-name>simple_videoDatasource</jndi-name>
  |       <connection-url>jdbc:mysql://localhost:3306/seam</connection-url>
  |       <driver-class>com.mysql.jdbc.Driver</driver-class>
  |       <user-name>seam</user-name>
  |       <password>seam</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>
  | 

I get this output in the log file:

  | 19:51:57,312 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: Failed to register driver for: com.mysql.jdbc.Driver; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: com.mysql.jdbc.Driver))
  | 
I tried three different versions of mysql-connector-java-bin.jar, the jar is located in the /lib directory and is added to the .classpath in the correct way.
I have the same problem when using the Oracle driver so it is probably not the driver class itself.

Any hint?

Thanks!
