    Question Jdbc connection mssql empty URL

    Hello i've got this code:

    Java Code:
    DatabaseManager.init("com.inet.tds.TdsDriver", "jdbc:inetdae:", "username", "password", 10);
    which links to:

    Java Code:
    public static void init(String JDBCDriver, String parURL, String parUserName, String parPassWord, int maxConnections) throws ClassNotFoundException, SQLException {
        URL = parURL;
        userName = parUserName;
        passWord = parPassWord;
    But gives me this fault:

    Java Code:
    DatabaseManager.getConnection() : java.sql.SQLException: The url cannot be null
    By this script:

    Java Code:
    public static void openConnection() throws SQLException{
        connection = DriverManager.getConnection(URL, userName, passWord);
    public static Connection getConnection() {
        try {
            if (connection!=null) {
                if (connection.isClosed())
            else {
        } catch (SQLException e) {
                System.out.println("deze fout: DatabaseManager.getConnection() : " + e);    
            return null;
        return connection;
    Does anyone have a clue why it tells me the url is empty?

    Please let me know if you need to see more scripting

    Default Re: Jdbc connection mssql empty URL

    It'll be in something you're not showing us.
    Where is URL defined?
    Log everywhere it is used/changed.
    Please do not ask for code as refusal often offends.
