I would like to address a mysql database in a macro:
I put the connector file (mysql-connector-java-3.0.15-ga-bin.jar) in the .jedit/jars directory and used the following statements:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
...
Class.forName("com.mysql.jdbc.Driver");
...
con = DriverManager.getConnection("jdbc:mysql://" + url + "/" + db, login, password);

But I got the error message:
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
