如何为RMI客户端设置静态客户端端口？

Question

I need a way to set a static port for rmi clients. The server uses a fixed port for it's connections but client side creates a dynamic port although I set a client socket factory.

The root cause I found is in the class "TCPChannel". In this class I see this code:

TCPEndpoint.getLocalEndpoint(0, (RMIClientSocketFactory)null, (RMIServerSocketFactory)null);

This clearly won't work as this code is unaware of my socket factory. Obviously this class is not RMI specific.

Question is - is there a way to override the tcp socket creation such that it doesn't create dynamic ports at all?

Answer 1

client side creates a dynamic port although I set a client socket factory.

You set it how? Whatever you did, you didn't do it correctly.

But why do it at all? There are lots of disadvantages. For one thing, it will cause all RMI calls from that client to be sequentialized, possibly at two-minute intervals, or possibly cause any calls at more frequent intervals to fail with BindExceptions .

For another, it may have an adverse effect on DGC.

And there is no actual benefit whatsoever.

Obviously this class is not RMI specific.

What class? And what's obvious about it?
