    Default Local Domain MySQL server, access denied

    I'm taking a shot at an SQL application in java, and I have "set up" a mysql server on 192.168.1.123 on my network.

    Here's what I did to install it on Ubuntu:
    sudo apt-get update
    sudo apt-get install mysql-server
    mysqladmin -u root -p create vtDB
    mysql -u -root -p mysql
    >INSERT INTO user (Host, User, Password, Select_priv) VALUES ('%', 'user', password('password'), 'Y');
    >FLUSH PRIVILEGES;
    >GRAND ALL PRIVILEGES ON vtDB.* TO 'user'@'%';
    >FLUSH PRIVILEGES;
    >exit
    mysqladmin -u root -p reload

    Here's the code that I am trying to use, it's all hard coded atm as I'm in the testing stage:

    try
    		{
     
    			System.out.println("Attempting to load JDBC Driver: com.mysql.jdbc.Driver");
    			Class.forName("com.mysql.jdbc.Driver").newInstance();
    			System.out.println("Driver Loaded, attempting connection");
    			String url = "jdbc:mysql://192.168.1.123:3306/";
    			Connection con = DriverManager.getConnection(url, "user", "password);
    			Statement s = con.createStatement();
    		    s.executeQuery("CREATE TABLE 2_29 (Standard VARCHAR(100), Unit VARCHAR(100), Topic VARCHAR(100), Level VARCHAR(100), Methods VARCHAR(500), Spiritual VARCHAR(500),  Academic VARCHAR(500), Artistic VARCHAR(500), Athletic VARCHAR(500), Service VARCHAR(500), i_GRADE INT, i_UNIT INT, i_TOPIC VARCHAR(100), m_GRADE INT, m_UNIT INT, m_TOPIC VARCHAR(100), r_GRADE INT, r_UNIT INT, r_TOPIC VARCHAR(100), LASTMOD TIMESTAMP(8)) TYPE=innodb");
    			System.out.println("Table Created");
     
    		}
    		catch (ClassNotFoundException cnfe) // driver not found
    		{
    			cnfe.printStackTrace();
    			System.err.println ("Unable to load database driver");
    			System.exit(0);
    		} catch (InstantiationException e) {
    			System.err.println ("Unable to load database driver");
    			e.printStackTrace();
    		} catch (IllegalAccessException e) {
    			System.err.println ("Unable to load database driver");
    			e.printStackTrace();
    		} catch (SQLException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}

    Here's the full error:

    java.sql.SQLException: Access denied for user 'user'@'192.168.1.2' (using password: YES)
    	at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:946)

    	at java.sql.DriverManager.getConnection(Unknown Source)
    	at BasicDatbaseTest.main(BasicDatbaseTest.java:18)

    I've tested everything locally, and the user can log in no problem and execute the exact same query.

    Default Re: Local Domain MySQL server, access denied

    First, can you use JDBC to login as root (this will test whether your computer can actually see the database regardless of the user you created)? Second, I don't recommend inserting directly into the user table. Rather, use the predefined SQL to create and modify user permissions:
    MySQL :: MySQL 5.1 Reference Manual :: 12.7.1.1 CREATE USER Syntax
