myCon not recognised

[Ian Cockcroft]

Hi all.
The following code is just a little utility to read data from a DAT file and put it in an access database.

  
import java.io.BufferedReader;
import java.util.StringTokenizer;
import java.io.*;
import java.sql.*;
public class UpdateAccessUtility
{
 public  static void main(String args[])
 {
  try
  {
   Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
  }
  catch (Exception e)
  {
   System.out.println("Failed to load 
                   JDBC/ODBC: "  + e);
   return;
  }
  try
  {
   String theURL = "jdbc :-o	 dbc:LKH";
   String userID = "";
   String passwd = "";
   Connection myCon = DriverManager.getConnection
             (theURL, userID, passwd);
  }
  catch(Exception e)
  {
    System.out.println("Connection failure: " + 
                                e);
  }
  try
  {
   BufferedReader in  = new BufferedReader(new 
   FileReader("C:\\LKHurwits\\lkh.dat"));
   String string;                        
   while ( (string = in.readLine()) != null ) 
   {                                
     StringTokenizer st1 = new StringTokenizer
          (string, "*");
      while (st1.hasMoreTokens())
      {
String str1 = st1.nextToken();
System.out.println(str1);
StringTokenizer st2 = new StringTokenizer
             (string, "|");
int i = 0;
  while(st2.hasMoreTokens())
  {
    ++i;
            String str2 = st2.nextToken();
            System.out.println(str2 + " " + i);
    if (i == 2)
     {
Statement stm = on.createStatement
                                  ();
stm.executeUpdate("insert into 
                Kidinfo (KidCode) values " + 
                str2);
     }
  }
}
}

    }
    catch(IOException io)
    {
    System.out.println("Error reading file" + 
      io );
     }
    }
}

(Its nothing special, I'm sure you guys have a better way of doing this.)
I am getting an error when I compile that it doesnt recognise myCon.
------- Compiler Output ------
UpdateAccessUtility.java:58: cannot resolve symbol
symbol : variable myCon
location: class UpdateAccessUtility
Statement stm = myCon.createStatement();

Any ideas? I have declared it in the same class.
Thanks guys
regards
Ian

You declare adn intialize myCon in a try block so that the variable is local to that block. Move the declaration outside of the block and you'll be ok with that part. You're going to need to catch the SQLException that can be thrown by that statement though. All you catch is an IOException after that try block.
hope that helps
