How JSP run automatically

Question

I would like to write a jsp file that can run in every 5 minutes.
My situation is that jsp file will include some sql statements which
will update a table in MS SQL Server according to some criteria.
The table need to be updated automatically to serve the business purposes.
So, i need a JSP file that can run automatically to serve this purpose.
Hope that some one can give some suggestion to me.
Thanks !

Answer 1

import java.util.Date;
import java.sql.*;
public class Test {
public static void main(String[] args) {
Connection conn = null;
String s1 = "";
PreparedStatement stmt = null;
ResultSet rset = null;
     while (true) {
     System.out.println("The time is "+new Date());
     try {
Thread.sleep(5*60*1000);
** place sqlserver to update table here
** example:
** java.util.Properties info = new java.util.Properties();
** info.put ("user", userid);
** info.put ("password", passwd);
** s1 = "jdbc:<database type>:thin:@" + host + ":" + port + ":" + database ;
** DriverManager.registerDriver ( new oracle.jdbc.driver.OracleDriver());
** conn = DriverManager.getConnection (s1,"scott","ctrl");
** s1 = "update table set column = ? where column = ?";
** stmt = conn.prepareStatement(s1);
** stmt.setString(1,var1);
** stmt.setString(2,vat2);
** rset = stmt.executeQuery();
** rset.close();
** stmt.close();
** conn.close();
} catch (Exception exc) {}
