[jboss-user] [Remoting] - Re: Remoting 2.5 SP1 - ServerInvoker.TIMEOUT does not work?

Ron, thank you for the explanation!

In fact, there really doesn't seem to be any point to setting the timeout value, since all we would do in the event of a timeout is go back and call ServerSocket.accept() again.

When i had looked at the code, i did infact see that the AcceptorThread was just accepting the connection and then the ServerThread was doing the actual work (as explained in the docs too).

I had been trying out this application with the following usecase:
- Connector (server) waits for commands (custom commands like startServer, stopServer, getServerStatus) on some url after calling the create and start remoting API
- Client can connect to the server using Remoting APIs and then send out requests which the ServerInvocationHandler will handle.
- All this was being done as part of a testcase. So if for some reason, the client never managed to connect to the server, i did not want the testcase to wait forever waiting for a client. That's where i was looking for a timeout functionality on the Conncetor.start() API. I think i will have to revisit my usecase.

This timeout value is used to set the timeout value for the Socket through which invocations will arrive from the client.  Given that network connections are a relatively scarce resource, it *does* make sense to let these sockets time out if an invocation is not forthcoming, rather than have them wait forever.

Makes sense. Thanks for the explanation :-)
