我试图弄清楚如何运行这个分布式对象演示让我头疼。我可以在同一台机器上本地运行它。
这是情况。我有一个服务器应用程序,它在远程计算机上生成一个客户端应用程序[使用OpenGLView]。
我可以使用AppleScript轻松完成这项工作。
客户端应用程序似乎是它的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)]);
}
Server App找到Port和Connection,但会引发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];
}
我无法弄明白为什么。
我进入客户端PC的控制台: “端口OK” “康恩OK” “Port 8081:Vend OK”
我进入服务器PC的控制台: “端口OK” “康恩OK” 11/18/09 2:05:36 PM DOTest3 [15278] [NSPortCoder sendBeforeTime:sendReplyPort:]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: 根据NSResponder的建议,我已经召集了控制器,但它仍然没有工作。
客户端/销售者:
-(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");
}
客户控制器:
-(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/(抓住商品)
-(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......我确信我只是在这里忽略了一些真正可靠的东西。
-S!

我从来没有见过有人试图在DO链接上销售视图或窗口,我很惊讶它甚至在本地主机上都有效。无论何时我使用DO,它都是从服务器控制器层中的对象到客户端中的相应控制器。
