The JDBC/ODBC driver is the type 1 driver it is also known as JDBC-ODBC bridge. It is ODBC driver to connect the database that convert the JDBC calls to ODBC function calls. Type 1 driver is fully platform dependent and use the native libraries of operating system. The ODBC driver must be installed in operating system. The Sun Microsystem provide JDBC-ODBC driver name as sun.jdbc.odbc.JdbcOdbcDriver but Oracle's JDBC-ODBC Bridge was removed in Java 8 for following reasons:-

Disadvantages

1. Performance issue the calls have to go through the JDBC bridge to the ODBC driver so it is slower than other types of drivers.
2. The ODBC driver must be installed on the client machine.
3. Creating Problem to run the applets, because the ODBC driver needs to be installed on the client.

In Java 8 we can read and write to Access databases without using ODBC with the help of UcanAccess driver. Java 8 provide an alternative option in place of JDBC-ODBC bridge because you not need to install ODBC in your system and compatible with both windows and non windows environments . UCanAccess is a pure Java JDBC driver which allow us to read from and write to Access databases without using ODBC. It uses at least two dependencies jackcess-2.1.2.jar and hsqldb.jar.

To connect with database(access,open office etc.) you can code like this:-

Connection conn=DriverManager.getConnection("jdbc:ucanaccess://C:/files/emp.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT empname FROM employees");
while (rs.next()) {
    System.out.println(rs.getString(1));
}
