on another database my java work fine and able connect. seems to be an issue at database level ?! what I need to fix at database level ?

adding the code of the connection:

public Connection getConnection() {     
    try {
        Class.forName(jdbcDriver);

        connection = DriverManager.getConnection(connectionString());
    }
    catch(Exception ex) {
        ex.printStackTrace();
        logger.error("Exception:" + ex.getMessage());
        errorMessage = ex.getMessage();
    }

    return connection;
}

where:

jdbc:mysql://127.0.0.1:3306/db?user=gda&password=gda

Answer 1

Try to pass the username and password in this manner:

String DB_URL = "jdbc:mysql://localhost/xyz";
String USER = "username";
String PASS = "password";

conn = DriverManager.getConnection(DB_URL,USER,PASS);
