Creating socket as below in the server side gives the exception. Can
any one guide why this happens so.
int newSocket = socket(AF_INET, SOCK_STREAM, 0);
struct sockaddr_in serverAddress;
int namelen = sizeof(serverAddress);
memset(&serverAddress, 0, sizeof(serverAddress));
serverAddress.sin_family = AF_INET;
serverAddress.sin_addr.s_addr = htonl(INADDR_ANY);
serverAddress.sin_port = htons(8081);
int yes = 1;
setsockopt(newSocket, SOL_SOCKET, SO_REUSEADDR, &yes, sizeof(yes));
bind(newSocket, (struct sockaddr *)&serverAddress, namelen);
listen(newSocket, 128);
NSSocketPort *receivePort = [[NSSocketPort alloc]
initWithProtocolFamily:PF_INET socketType:SOCK_STREAM protocol:0
socket:newSocket];
NSConnection *connection = [NSConnection
connectionWithReceivePort:receivePort sendPort:receivePort];
if i create the port as below then it doesn't gives the exception
NSSocketPort *receivePort;
NSConnection *connection;
NSRunLoop *runloop = [NSRunLoop currentRunLoop];
// Magic fix for socketPort/host leaks!
if ([NSHost respondsToSelector:@selector(_fixNSHostLeak)]) {
[NSHost _fixNSHostLeak];
}
if ([NSSocketPort respondsToSelector:
@selector(_fixNSSocketPortLeak)]) {
[NSSocketPort _fixNSSocketPortLeak];
}
NS_DURING
// This server will wait for requests on port 8081
receivePort = [[NSSocketPort alloc] initWithTCPPort:PORT_NUMBER];
NS_HANDLER
exit(-1);
NS_ENDHANDLER
// Create the connection object
connection = [NSConnection connectionWithReceivePort:receivePort
sendPort:nil];
[receivePort release];
[connection enableMultipleThreads];
[connection setRootObject:[ServerObject sharedServerObject]];
[connection addRunLoop:runloop];
[connection setDelegate:self];
[receivePort release];

hi ken,
So, the questions are: is -getServer called on the main thread? Is
the client object, the one which you pass to the server with -
registerClient:. retained so that it is still alive when the ping
comes?
the object i send is shared object, which exist until the
application quits.
Regards
SKiran

I am developing a client/server application using DO. In server

server and server replies to that. But on serverside if any
updates goes, i had to inform client.so i thought of registering
the client and ping the client for updates.So in Client side i
get vended object and registered it to server.When my server
pings the client its giving error *** NSDistantObject

Can you break on this error? On what line of code is it
happening? What's the backtrace?
this exception occurs when server pings,

It looks like the above is separate from the below exception,
although probably related. That message is far from clear. An
Apple engineer may be able to help.
It seems to be saying that it has received an object identifier
(0x1) which doesn't correspond to any object that was sent out on
the connection in question.
