{
Properties props =
new
Properties();
props.load(fs);
String url = props.getProperty(
"db.url"
);
String userName = props.getProperty(
"db.user"
);
String password = props.getProperty(
"db.password"
);
Class.forName(driverClass);
con=DriverManager.getConnection(url, userName, password);
}

void
fetch()
