No connection and without a reason

[Paolo Parise]

Hi,
I have problem connecting to a database, and no exceptions are raised.

This is my class.

public class db {

    Connection connection;
    static
    {
        try {
            Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
            System.out.println("driver ok");
        } catch (ClassNotFoundException e) {
            System.out.println("the class driver cannot be loaded");
        }
    }

    public Connection connect(String database_name) throws SQLException 
    {
        String filename = io.PATH_DB + database_name + ".mdb";
        String database = "jdbc:ucanaccess://";
        database += filename.trim();
        System.out.println(database);
        try
        {
            connection = DriverManager.getConnection(database); 
            System.out.println("Ok connection");
        }
        catch(Exception e)
        {
            io.error("Connessione al database " + database_name + " non riuscita");
            connection = null;
            System.out.println(e);  
            e.printStackTrace();
        }
        return connection;
    }

drivers and libraries are ok, as I can see in the console, I can see the connection string that is
jdbc:ucanaccess://C:\Users\paolo.SCRIPTA\YandexDisk\java\base\database\pagheorg.mdb
and I cannot see console log "ok connection" but even any fault trace.

It seems that the execution stops on getConnection row.

What am I doing wrong? Is it a normai behaviour?
I'm using 4.0.4 version.

Thank you!

It is only very slow in execution, my fault. It works.
