Currently, I could get the connectivity between client and Server using their Public Ip and port "80". After TCP connection is established I could retrieve the Stub info of RMIServer. Also, I could netstat and see the connection established. But When trying read the remote object I'm getting following exception java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is: java.net.SocketTimeoutException: Read

timed out at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:293) at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:190) On monitoring the connectivity with netstat, I could see the TCP connection gets terminated immediately and its not stable. It would be helpful If I could get any hints on how to maintain or get a stable TCP connection. Thanks. java sockets tcp share|improve this question asked May 16 '14 at 13:22 skmr 613 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote The timeout error indicates you were able to open a socket between the client and the server, but that the socket was not serviced in a timely manner, so it closed and gave you that exception. The last time this happened to me, it happened because the client could not find the correct class libraries in its path. The server attempted to open a socket, the client went off looking for the class library and didn't find it, the socket eventually timed out. Double check the class path of both your client and server. share|improve this answer answered May 16 '14 at 16:04 bpendell 12 You have client and server back to front here. Clients open connections: servers accept them. The client got the read timeout, so it was the server that wasn't responding. –EJP May 16 '14 at 22:54 I've seen it ha

I would like to ask regarding this error. java.rmi.ConnectIOException: http://stackoverflow.com/questions/23696170/rmi-client-server-java-rmi-connectioexception-error-during-jrmp-connection-es error during JRMP connection establishment This error occured when Naming.lookup() method tries to look into the RMI registry. The case is that RMI will be used to invoke methods on an EJB. The setup is: 1. EJBs are deployed in a Websphere server (WAS). 2. All servers will be on my local machine, so is the RMI Registry. Do I still need additional https://community.oracle.com/thread/1178615?start=0 setup for WAS regarding the use of RMI Registry? Thanks! By the way, my WAS is using Java 1.5.
