Opening and closing database from JSPs

Question

Hi,
I have a few web pages with an underlying database, and after some research I seem to have found that accessing this database directly from the JSP is a bad idea. Because of this I have created 2 methods in my JavaBean class to create the database connection and to close the database connection. What I want to have happen is when the user logs in the the site, a database connection is opened by calling the databaseConnection method then once they close the browser the destroyDBConnection is called. How do I go about implementing this approach in my JSPs? thanks for any suggestions
    * Method to create database connection
    public static void dbConnection() {
      try{
          // Step 1: Load the JDBC driver.
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            // Step 2: Establish the connection to the database.
            String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};" +
                    "DBQ=C:\\Program Files\\Apache Software Foundation\\Tomcat 5.5" +
                    "\\webapps\\TheatreDepartment.mdb";
            connection = DriverManager.getConnection(url);
          connection.setAutoCommit(false);
      } catch (SQLException se) {
          System.out.println("SQL Error while connecting to the database : "+
                              se.toString());
      } /*catch (NamingException ne) {
          System.out.println("Naming exception Error while connecting to the database : "+
                              ne.toString());
      } */catch (Exception ne) {
          System.out.println("Error while connecting to the database : "+
                              ne.toString());
    * Destroy the Connection Object.
    public static void destroyDbConnection() throws SQLException {
          if (connection != null || !connection.isClosed() ) {
            connection.close(); // close the connection
  }

I would suggest you do some more research.
Take a look into connection pooling.
Most of the time you do NOT want to give each individual user their own database connection, but rather keep a bunch on hand for people to use.
