To be honest i do not know your application, but:

this looks like you have to do some configuration work in your application. For a host to open a connection it has to have a daemon running which is listening to the port where the connection is attempted.

For instance: let's say you contact a web server. This means your browser creates a message, sends it to the target server, port 80 (or whatever is configured, but 80 is the default). Behind port 80 on the target server lurks the web server process (Apache, ...), which picks the message up, does something and sends a message back (like: serves up a web page). If the web server would not listen behind port 80, nothing would happen at all - the host would "refuse the connection".

This is why i think you simply have nobody listening behind port 1521, so that no connection comes to pass.

I hope this helps.
