[JBoss-user] [Installation & Configuration] - Re: how to avoid JNDI port conflicts at startup?

Yes, we definitely need to change the port number.

The question is, is there a way to pick a fixed port number that will basically never have conflicts.

I'm running on a Windows 2000 system. We had been using port 1099 for JNDI, but it seems that sometimes, some other process has grabbed that port. As I understand it, a port numbered over 1023 can be grabbed by basically any process. And such ports are typically chosen dynamically to create socket connections for other protocols like HTTP.

1099 is pretty close to 1023, and I believe these dynamically-assigned ports are generally chosen in increasing numerical order. So if I pick a much higher port number, like 11099, it's very unlikely to be used either for a dynamically-assigned port, or as the "well known port" for some other protocol. Just as 8080 works well as an alternate port for HTTP.

So is this solution the standard one? Is it reliable? Is there a better way?

Thanks in advance.
