Hi,

I'm new here so, first, I want to greet everyone.

This is my problem:
In a program that is installed on a computer, part of a local network, I tried, many time and without success, to get a SQL connection to another computer of the same net where is running a Derby server database.

I have not a big experience with a such kind of problem; that is way I think that not all that I wrote in the code can be exact and so I hope to have some help to correct it.

In my work I start the server, at run time, from a program installed on the same computer where the database is stored, using this code:


I get this feed back, when the code run and the server starts:


=============( S E R V E R  is  S T A R T E D): =============
InetAddress : zorro/10.0.0.5
Informazioni di runtime :
--- Informazioni di runtime sul server di rete Derby ---
---------- Informazioni di sessione ---------------
N. sessioni :1
-------------------------------------------------------------
N. thread di collegamento : 1
N. sessioni attive : 1
N. sessioni in attesa : 0
Memoria totale : 16318464    Memoria disponibile : 14913416
N.B. Zorro is the name of the computer in the local Network.


After that the server started, they are not problems to get a connection and to use the database in the same program that started the server (i.e. in the same computer where the database is stored).

But if I try to have a connection from a program that is installed on another computer, part of the same local network, always I get this error:


ava.sql.SQLNonTransientConnectionException: java.net.ConnectException : Error connecting to server 10.0.0.4 on port 1527 with message Connection refused: connect.


To get the remote connection (in the method DriverManager.getConnection(connectionURL)), I use this string argument:


The firewall is disabled, ...so the problem cannot depend to this cause.

I hope to have some advice to solve my problem.

Thank you
Regards
Angelo.
