SQLite异常路径不存在

Question

I am trying to connect an already existing SQLite database to my java project, as a temporary solution for testing a simple log-in dialog. Here is my connector class:

import java.sql.*;
import javax.swing.*;

public class SQLite_login_connector {
//Initializes global connection variable (unused until now!)
Connection conn_log = null;

public static Connection logindb_connection(){

    //Simple try catch block that prints error trace log in a JOptionPane if runtime error occurs.

    try{
        Class.forName("org.sqlite.JDBC");

        Connection conn_log = DriverManager.getConnection("jdbc:sqlite:/SQLite/ISRSMS_Login.sqlite");
        JOptionPane.showMessageDialog(null, "Connection Successful!");
        return conn_log;

    }   catch(Exception e){
        JOptionPane.showMessageDialog(null, e);
        return null;
    }       
  }
 }

My SQLite database is located in a folder within my project folder:

When I try running my connector class, it throws the following exception:

For me it looks as if it assumes that the folder which contains my database is located on my F: drive, as opposed to my root project in my local repository. I have tried putting the database into my src folder, as well as into a new resource folder all-together. Every time it throws the same exception. Why does it do that?

Answer 1

As you have metntioned / in yor connection string it is pointing to the root directory of your drive Remove the / in your connection string Do as follows

 DriverManager.getConnection("jdbc:sqlite:SQLite/ISRSMS_Login.sqlite")

For your convenience please follow the naming convention of java language http://www.oracle.com/technetwork/java/codeconventions-135099.html

Answer 2

Why is your URL .sqllite? I would expect .db - like here

jdbc:sqlite:C:/mydir/mydb.db
