Multiple JDBC files on Eclipse project

In my project, I should use both SQLiteDB and MariaDB.

So, I imported jdbc driver files(*.jar) in the eclipse project.

But I got an error like this:

Code:

    try {
        driver = (Driver) Class.forName("org.sqlite.JDBC").newInstance();
        DriverManager.registerDriver(driver);
    } catch (SQLException e) {
        e.printStackTrace();
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (InstantiationException e) {
        e.printStackTrace();
    }

Error message:

Exception in thread "main" java.lang.IllegalArgumentException: Invalid connection URL url jdbc:sqlite:data.sqlite
at org.mariadb.jdbc.JDBCUrl.parse(JDBCUrl.java:144)
at org.mariadb.jdbc.Driver.connect(Driver.java:95)
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at database.DBHelper.makeConnections(DBHelper.java:96)
at database.DBHelper.<init>(DBHelper.java:60)
at database.DBHelper.getSingleton(DBHelper.java:28)

I clearly registered the jdbc driver with the name "org.sqlite.JDBC". But I don't know why the log message contains "at org.mariadb.jdbc.Driver.connect(...)".

After the MariaDB jdbc file(*.jar) is removed, the program is successfully executed.
