* Синтаксическая ошибка *
У меня проблема с JDBC.
В этой строке:
Connection con =DriverManager.getConnection("jdbc:odbc:recordtbl","scott","tiger");
здесь при ошибке con появляется, что я переименовываю эту переменную.
Это мой код:
package md5IntegrityCheck;
import java.io.UnsupportedEncodingException;
import java.security.NoSuchAlgorithmException;
import java.util.Scanner;
import java.sql.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MD5IntegrityCheck
{
public static void main(String[] args)
throws UnsupportedEncodingException, NoSuchAlgorithmException
{
Statement stmt;
ResultSet rs;
Connection con=null;
PreparedStatement pst=null;
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con =DriverManager.getConnection("jdbc:odbc:recordtbl","scott","tiger");
}
catch(Exception ee)
{ee.printStackTrace( );}
System.out.println("Step 1");
System.out.println(con.isClosed());
System.out.println("Enter the filename");
Scanner scanner = new Scanner(System.in);
String filename=scanner.nextLine();
String chksumno="somevalue2";
// get the file name here and store it in filename variable;
MD5 md5 = new MD5(filename);
System.out.println("test");
chksumno = md5.getHashValue();
System.out.println("Step 2");
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection("jdbc:odbc:recordtbl","scott","tiger");
pst=con.prepareStatement("insert into recordtbl values(?,?)");
//System.out.println(pst.isClosed());
System.out.println("Step3");
pst.setString(1,filename);
System.out.println("Step 4");
pst.setString(2,chksumno);
System.out.println("Step 5");
pst.execute();
System.out.println("Statement was EXECUTED!");
con.close( );
}
catch(Exception ee)
{ee.printStackTrace( );}
if (args.length <= 0)
{
Md5Gui gui = new Md5Gui();
gui.runGui();
}
else
{
DoWork runningProgram = new DoWork();
runningProgram.run(args);
}
}
}
