Question

I’m trying to use weka reading data from my local MySql database.

I put DatabaseUtils.prop in my home directory and launch weka as a command. I receive this message

Trying to add database driver (JDBC): com.mysql.jdbc.Driver - Error, not in CLASSPATH?

But the file is being loaded, since when I try to connect, the url is already set as in my config file.

I tried to run weka from its folder using

java -cp ./mysql-connector-java-5.12-bin.jar -jar weka.jar

but this isn’t working neither, since apparently using -jar “overrides the classpath variable” (quoted since I don’t know what does that mean)

Answer 1

Solved

I used this command

java  -Xmx300M -cp ".:weka.jar:mysql-connector-java-5.1.12-bin.jar:"   weka.gui.GUIChooser

found here, to whom I replaced ‘;’ with ‘:’ because apparently this is how it works on Linux
