Trying to add database driver (JDBC): RmiJdbc.RJDriver - Error, not in CLASSPATH?

java, weka

Solution

Nothing is wrong. weka.jar has a DatabaseUtils.props file in it. This file has following line in subversion therefore weka tries to load that drivers.

jdbcDriver=RmiJdbc.RJDriver,jdbc.idbDriver,org.gjt.mm.mysql.Driver,com.mckoi.JDBCDriver,org.hsqldb.jdbcDriver

Open jar file with a zip utility and look for weka\experiment\DatabaseUtils.props file.

Problem

I am using Weka ``` import weka.core.Instances; import weka.core.converters.ConverterUtils.DataSource; . . DataSource source; source = new DataSource("somecsvfile.csv"); ``` I get following printed on console in red color in eclipse: ``` ---Registering Weka Editors--- Trying to add database driver (JDBC): RmiJdbc.RJDriver - Error, not in CLASSPATH? Trying to add database driver (JDBC): jdbc.idbDriver - Error, not in CLASSPATH? Trying to add database driver (JDBC): org.gjt.mm.mysql.Driver - Error, not in CLASSPATH? Trying to add database driver (JDBC): com.mckoi.JDBCDriver - Error, not in CLASSPATH? Trying to add database driver (JDBC): org.hsqldb.jdbcDriver - Error, not in CLASSPATH? ``` What's wrong?
