我想弄清楚如何运行这个分布式对象演示,这让我自己感到头疼。我可以在同一台机器上在本地运行得很好。
情况就是这样。我有一个服务器应用程序,它在远程机器上生成带有OpenGLView的客户端应用程序。
我可以用AppleScript轻松地做到这一点。
客户端应用程序似乎提供了它的OpenGLView窗口OK:
clientPort = [[NSSocketPort alloc] initWithTCPPort:SERVER_PORT];
if(clientPort == nil) continue; else NSLog(@"Port OK");
clientConnection = [NSConnection connectionWithReceivePort:clientPort sendPort:nil];
if(clientConnection == nil) continue; else NSLog(@"Conn OK");
[[NSSocketPortNameServer sharedInstance] registerPort:clientPort name:@"DOTest3_0"];
//Vend Object
@try {
[clientConnection setRootObject:object];
NSLog([NSString stringWithFormat:@"Port %d: Vend OK", (SERVER_PORT + i)]);
return;
} @catch (...) {
NSLog([NSString stringWithFormat:@"Port %d: Vend Next", (SERVER_PORT + i)]);
}服务器应用程序找到端口和连接,但引发TimeOut异常:
// Create temporary Pointer to kGLView Object.
id <NSCoding, kGLViewProtocol> openGLView;
// Setup Port, Connection, & Proxy
portTest = (NSSocketPort *)[[NSSocketPortNameServer sharedInstance] portForName:@"DOTest3_0" host:@"*"];
if (portTest == nil ) continue ; else NSLog(@"Port OK");
connTest = [NSConnection connectionWithReceivePort:nil sendPort:portTest];
if (connTest == nil ) continue ; else NSLog(@"Conn OK");
openGLView = [[connTest rootProxy] retain];
if (openGLView == nil ) continue ; else NSLog(@"OpenGL OK");
[openGLView drawWithRotation: rotationAngle];
}我想不出为什么。
我进入了客户端PC的控制台:“端口确定”"Conn OK“”端口8081: Vend OK“
我进入服务器PC的控制台:“端口确定”"Conn“11/18/09 2:05:36 PM DOTest315278超时(10280263936.092180 280263936.092642) 1
即使TimeOuts都设置为60秒。
帮助!

服务器: MacMini OS X 10.5客户端: MacPro OS X 10.6远程登录、管理等都已启用。
编辑:接受NSResponder的建议,我已经支持了控制器,但它仍然不起作用。
客户/供应商:
-(void)vend:(id)object {
port = [[[NSSocketPort alloc] initWithTCPPort:[self tcpPort]]
retain];
conn = [[NSConnection connectionWithReceivePort:port sendPort:nil]
retain];
for (int i = 0; i < 10; i++) {
[[NSSocketPortNameServer sharedInstance] registerPort:port
name:[[self portName] stringByAppendingFormat:@"_%d", i]];
@try {
[conn setRootObject:object];
return;
} @catch (...) {
NSLog(@"Vend Next");
continue;
}
}
NSLog(@"Vend Failed");
}客户财务主任:
-(id)init {
self = [super init];
[self setRotationAngle:0.0f];
clientObj = [[Client alloc] initWithName:@"DOTest4"
Address:@"10.10.5.104" // mini
Port:48557];
[clientObj vend:self];
return self;
}服务器控制器:
-(IBAction)rotateClient:(id)sender {
NSArray *vendedObjects = [serverObj getVendedObjects];
id <NSCoding, ClientController_Protocol> proxy;
if (vendedObjects != nil) {
for (int i = 0; i < [vendedObjects count]; i++) {
proxy = [vendedObjects objectAtIndex:i];
[proxy rotate];
}
}
// release
[vendedObjects release];
}服务器/(抓取已获得的对象)
-(NSArray *)getVendedObjects {
NSArray *vendedObjects = [[[NSArray alloc] init] retain];
NSSocketPort *port;
NSConnection *conn;
for (int i = 0; i< 10; i++) {
// Get Port Object
port = (NSSocketPort *)[[NSSocketPortNameServer sharedInstance]
portForName:[[self portName] stringByAppendingFormat:@"_%d", i]
host:[self addressRemote]];
if (port == nil) continue;
// Create Connection with Timeouts
conn = [NSConnection connectionWithReceivePort:nil sendPort:port];
if (conn == nil) continue;
[conn setReplyTimeout:(NSTimeInterval)60.0];
[conn setRequestTimeout:(NSTimeInterval)60.0];
// Get VendedObject of Connection
vendedObjects = [[vendedObjects arrayByAddingObject:[conn rootProxy]] retain];
}
return vendedObjects;
}叹息..。我肯定我只是忽略了一些真正的可可-基本的东西。

我从未见过有人试图在DO链接上播放视图或窗口,甚至在本地主机上,我也很惊讶。无论何时我使用它,它都是从服务器的控制器层中的对象到客户机中的相应控制器。
