Problemer

Jeg får følgende fejl når jeg forsøger at oprette forbindelse til min mssql-database via java:

[Microsoft][ODBC Driver Manager] Invalid string or buffer length

Filen jeg bruger til at oprette forbindelsen, kan ses her:

package DBLayer;

import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;

public class DBConnection {

    //constans used to get access to the database
    //SQL Server
    private static final String  driver = "jdbc:odbc:";
      //MySql
    //private static final String  driver = "jdbc:mysql://localhost:3306/";

            System.out.println(e.getMessage());
        }//end catch
        try{

            //set autocommit
            con.setAutoCommit(true);
            dma = con.getMetaData(); // get meta data

            System.out.println("Driver " + dma.getDriverName());
            System.out.println("Database product name " + dma.getDatabaseProductName());
        }//end try
        catch(Exception e){
            System.out.println("Problems with the connection to the database");
            System.out.println(e.getMessage());
        }//end catch
    }//end  constructor

  //closeDb: closes the connection to the database
    public static void closeConnection()
    {
          try{
            con.close();
            System.out.println("The connection is closed");
        }
        catch (Exception e){
            System.out.println("Error trying to close the database " +  e.getMessage());
        }
    }//end closeDB

    //getDBcon: Get-metode, returnerer forbindelsen til databasen
    public  Connection getDBcon()
    {
      return con;
    }
    //this method is used to get the instance of the connection
    public static DBConnection getInstance()
    {
        if (instance == null)
        {
          instance = new DBConnection();
        }
        return instance;
    }

}//end DbConnection

Så vidt jeg kan se, drejer det sig om, at jeg forsøger at indsætte en værdi der ikke passer til den tabel jeg forsøger at sætte det ind i, men jeg kan ikke se hvor jeg sætter noget ind i databasen.
