This is most likely due to missing, misplaced, or incompatible database driver. Please make sure that you have a JDBC driver that is compatible with your database server and in the correct location:

  • For Apache, the driver is usually located in the /lib folder.
  • For Websphere, you can specify where the driver is located when you create the JDBC Provider in the WebSphere administration GUI.
  • For JBoss, the driver should be placed in the /server/default/lib folder.
  • For Weblogic, the Oracle driver should have been included with the application server installation.
