I'm using JBoss 3.2 and I am having problems acquiring a database connection to a sybase database.

When my code tries to get a connection, JBoss complains that my driver is already registered. Has anyone else had similar problems?

I have supplied the error below:
[org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory] Driver not yet registered for url: jdbc:inetsyb:172.19.200.11:5000?database=stoccaprd
[org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory] Driver already registered for url: jdbc:inetsyb:172.19.200.11:5000?database=stoccaprd
