JdbcURL specifies the JDBC URL pointing to your database (can be still changed in the Experimenter/Explorer), e.g. ODBC - part of Sun's JDKs/JREs, no external driver necessary.MS SQL Server 2000 (Desktop Edition) - .SQLServerDriver.

JdbcDriver is the classname of the JDBC driver, necessary to connect to your database, e.g.: Under normal circumstances you only have to edit the following two properties: If you take one of the example files listed above, you need to rename it first. Note: Weka only looks for the DatabaseUtils.props file. For more information on how property files are processed, check out this article. The easiest way is just to place the extracted properties file into your HOME directory. - ODBC access via Sun's ODBC/JDBC bridge, e.g., for MS Sql Server (see the Windows Databases article for more information).- MS Access (see the Windows Databases article for more information).Weka comes with example files for a wide range of databases: If you open up one of those files, you'll find the properties file in the sub-folder weka/experiment. You can get this properties file from the weka.jar or weka-src.jar jar-archive, both part of a normal Weka release. Responsible for the setup is the following properties file, located in the weka.experiment package: DatabaseUtils.props Thanks to JDBC it is easy to connect to Databases that provide a JDBC driver. See the CLASSPATH article for how to set up your CLASSPATH environment variable, in order to make the JDBC driver available for Weka.
