warning about jdbc driver

RapidQues

Kindly explain this warning:

WARNING: Missing database driver class name for ODBC Bridge (e.g. Access)
Mar 05, 2014 2:55:12 PM com.rapidminer.tools.jdbc.JDBCProperties registerDrivers
INFO: JDBC driver ca.ingres.jdbc.IngresDriver not found. Probably the driver is not installed.

this occurs when i try to change the parameter of some operator through java program.

Thanks

Hi,

simply means that neither an odbc <-> jdbc bridge driver, nor the ingres jdbc driver could be found in the lib/jdbc folder of RapidMiner Studio.
Can be ignored unless you want to use either of these
