RMI Sockets

[Reinhard Achleitner]

Hi!

Let me explain my problem i have with RMI:

I have a server application running behind a Router
I have clients running also behind routers.

The server and the client communicates with RMI. Also Callbacks from server
to client has to be made.

After hours of experimenting it works that the client can connect to the
server and receive callbacks from server.
To do this, i use two ports (one for the registry and one for the other
communication) and open this ports in the routers.

A Call to the server has always three steps:

1.) Call the server method
2.) Start a new Thread and create the result
3.) Send back the result via callback

The problem i have is, that if the creating of the result takes a little bit
longer (> 10 seconds approximatly) then
i get following exception:

java.rmi.MarshalException: error marshalling arguments; nested exception is:
java.net.SocketException: Connection reset by peer: socket write error
