Looking at this line in the code, i guess this belongs to your application and this piece of code is passing the connection to the oracle driver method which probably excepts it to be of a different type.

In your com.vitechinc.core.model.BlobType.nullSafeSet you might want to do something like:

  | DataSource ds = ctx.lookup("dsname");
  | Connection conn = ds.getConnection();
  | // JBoss returns a "JBoss specific" wrapped connection, so let's give it a try
  | if (conn instanceof org.jboss.resource.adapter.jdbc.WrappedConnection)
  | {
  |  Connection underlyingConnection = ((WrappedConnection) conn).getUnderlyingConnection();
  |  // pass it on to the oracle driver
  |  
  | }
  | else {
  |  // pass the connection as-is to the driver
  | }

All this is a guess, based on the stacktrace. Not sure whether this is going to work.
