Answer 1

Here a simple typical oracle connection code :
Connection connection = null;
    try {
        // Load the JDBC driver
        String driverName = "oracle.jdbc.driver.OracleDriver";
        Class.forName(driverName);
        // Create a connection to the database
        String serverName = "127.0.0.1";
        String portNumber = "1521";
        String sid = "mydatabase";
        String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
        String username = "username";
        String password = "password";
        connection = DriverManager.getConnection(url, username, password);
    } catch (ClassNotFoundException e) {
        // Could not find the database driver
    } catch (SQLException e) {
        // Could not connect to the database
    }You can take a look [here |http://courses.coreservlets.com/Course-Materials/csajsp2.html] (http://courses.coreservlets.com/Course-Materials/csajsp2.html) for JSP, Servlets, MVC pattern
and [here |http://courses.coreservlets.com/Course-Materials/msajsp.html] (http://courses.coreservlets.com/Course-Materials/msajsp.html) for database connection.
You'll also find there many other useful resources.
good luck
