Мой код компилируется и отлично работает в Eclipse, но когда я пытаюсь превратить его в .jar, он выдает мне кучу ошибок.
Код, файл .bat, который я использую для компиляции.jar и мое сообщение об ошибке можно найти здесь:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.util.Scanner;
import com.mysql.jdbc.PreparedStatement;
public class Main
{
private static Scanner scn = new Scanner(System.in);
public static void main(String[] argv) throws Exception
{
Class.forName("com.mysql.jdbc.Driver");
Main main = new Main();
int choice = 0;
System.out.println("\t\tWelcome !\n\n");
System.out.print(
"1. Get Data From the table \"testtable\"\n"+
"2. Insert data into the table \"testtable\"\n"+
"Your choice?: "
);
choice = scn.nextInt();
scn.nextLine();
switch( choice )
{
case 1:
main.getInfo();
break;
case 2:
main.insertInfo();
break;
default:
System.out.print("Was neither 1 or 2. Terminating program...");
}
}
private void getInfo() throws Exception
{
//Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/testdb", "guest", "shahin33");
PreparedStatement statement = (PreparedStatement) con.prepareStatement("SELECT * FROM testtable");
ResultSet result = statement.executeQuery();
System.out.println();
System.out.println("USERNAME\tPASSWORD");
while( result.next() )
{
System.out.println(result.getString(1) + "\t\t" + result.getString(2));
}
result.close();
con.close();
}
private void insertInfo() throws Exception
{
System.out.print("\nUsername: ");
String username = scn.nextLine();
System.out.print("Password: ");
String password = scn.nextLine().toLowerCase();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/testdb", "guest", "shahin33");
PreparedStatement statement = (PreparedStatement) con.prepareStatement("INSERT INTO testtable VALUES(?,?)");
statement.setString(1, username);
statement.setString(2, password);
statement.executeUpdate();
System.out.println("\nUser information has been inserted to the database.\nRun the program again and chose 1 to see result.");
statement.close();
con.close();
}
}
.bat файл, который я использую для компиляции в .jar:
