  • Streaming a webcam from Silverlight 4 (Beta)

    - by Ken Smith
    The new webcam stuff in Silverlight 4 is darned cool. By exposing it as a brush, it allows scenarios that are way beyond anything that Flash has. At the same time, accessing the webcam locally seems like it's only half the story. Nobody buys a webcam so they can take pictures of themselves and make funny faces out of them. They buy a webcam because they want other people to see the resulting video stream, i.e., they want to stream that video out to the Internet, a lay Skype or any of the dozens of other video chat sites/applications. And so far, I haven't figured out how to do that with It turns out that it's pretty simple to get a hold of the raw (Format32bppArgb formatted) bytestream, as demonstrated here. But unless we want to transmit that raw bytestream to a server (which would chew up way too much bandwidth), we need to encode that in some fashion. And that's more complicated. MS has implemented several codecs in Silverlight, but so far as I can tell, they're all focused on decoding a video stream, not encoding it in the first place. And that's apart from the fact that I can't figure out how to get direct access to, say, the H.264 codec in the first place. There are a ton of open-source codecs (for instance, in the ffmpeg project here), but they're all written in C, and they don't look easy to port to C#. Unless translating 10000+ lines of code that look like this is your idea of fun :-) const int b_xy= h->mb2b_xy[left_xy[i]] + 3; const int b8_xy= h->mb2b8_xy[left_xy[i]] + 1; *(uint32_t*)h->mv_cache[list][cache_idx ]= *(uint32_t*)s->current_picture.motion_val[list][b_xy + h->b_stride*left_block[0+i*2]]; *(uint32_t*)h->mv_cache[list][cache_idx+8]= *(uint32_t*)s->current_picture.motion_val[list][b_xy + h->b_stride*left_block[1+i*2]]; h->ref_cache[list][cache_idx ]= s->current_picture.ref_index[list][b8_xy + h->b8_stride*(left_block[0+i*2]>>1)]; h->ref_cache[list][cache_idx+8]= s->current_picture.ref_index[list][b8_xy + h->b8_stride*(left_block[1+i*2]>>1)]; The mooncodecs folder within the Mono project (here) has several audio codecs in C# (ADPCM and Ogg Vorbis), and one video codec (Dirac), but they all seem to implement just the decode portion of their respective formats, as do the java implementations from which they were ported. I found a C# codec for Ogg Theora (csTheora, http://www.wreckedgames.com/forum/index.php?topic=1053.0), but again, it's decode only, as is the jheora codec on which it's based. Of course, it would presumably be easier to port a codec from Java than from C or C++, but the only java video codecs that I found were decode-only (such as jheora, or jirac). So I'm kinda back at square one. It looks like our options for hooking up a webcam (or microphone) through Silverlight to the Internet are: (1) Wait for Microsoft to provide some guidance on this; (2) Spend the brain cycles porting one of the C or C++ codecs over to Silverlight-compatible C#; (3) Send the raw, uncompressed bytestream up to a server (or perhaps compressed slightly with something like zlib), and then encode it server-side; or (4) Wait for someone smarter than me to figure this out and provide a solution. Does anybody else have any better guidance? Have I missed something that's just blindingly obvious to everyone else? (For instance, does Silverlight 4 somewhere have some classes I've missed that take care of this?)

  • Why wont a simple socket to the localhost connect?

    - by Jake M
    I am following a tutorial that teaches me how to use win32 sockets(winsock2). I am attempting to create a simple socket that connects to the "localhost" but my program is failing when I attempt to connect to the local host(at the function connect()). Do I need admin privileges to connect to the localhost? Maybe thats why it fails? Maybe theres a problem with my code? I have tried the ports 8888 & 8000 & they both fail. Also if I change the port to 80 & connect to www.google.com I can connect BUT I get no response back. Is that because I haven't sent a HTTP request or am I meant to get some response back? Here's my code (with the includes removed): // Constants & Globals // typedef unsigned long IPNumber; // IP number typedef for IPv4 const int SOCK_VER = 2; const int SERVER_PORT = 8888; // 8888 SOCKET mSocket = INVALID_SOCKET; SOCKADDR_IN sockAddr = {0}; WSADATA wsaData; HOSTENT* hostent; int _tmain(int argc, _TCHAR* argv[]) { // Initialise winsock version 2.2 if (WSAStartup(MAKEWORD(SOCK_VER,2), &wsaData) != 0) { printf("Failed to initialise winsock\n"); WSACleanup(); system("PAUSE"); return 0; } if (LOBYTE(wsaData.wVersion) != SOCK_VER || HIBYTE(wsaData.wVersion) != 2) { printf("Failed to load the correct winsock version\n"); WSACleanup(); system("PAUSE"); return 0; } // Create socket mSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); if (mSocket == INVALID_SOCKET) { printf("Failed to create TCP socket\n"); WSACleanup(); system("PAUSE"); return 0; } // Get IP Address of website by the domain name, we do this by contacting(??) the Domain Name Server if ((hostent = gethostbyname("localhost")) == NULL) // "localhost" www.google.com { printf("Failed to resolve website name to an ip address\n"); WSACleanup(); system("PAUSE"); return 0; } sockAddr.sin_port = htons(SERVER_PORT); sockAddr.sin_family = AF_INET; sockAddr.sin_addr.S_un.S_addr = (*reinterpret_cast <IPNumber*> (hostent->h_addr_list[0])); // sockAddr.sin_addr.s_addr=*((unsigned long*)hostent->h_addr); // Can also do this // ERROR OCCURS ON NEXT LINE: Connect to server if (connect(mSocket, (SOCKADDR*)(&sockAddr), sizeof(sockAddr)) != 0) { printf("Failed to connect to server\n"); WSACleanup(); system("PAUSE"); return 0; } printf("Got to here\r\n"); // Display message from server char buffer[1000]; memset(buffer,0,999); int inDataLength=recv(mSocket,buffer,1000,0); printf("Response: %s\r\n", buffer); // Shutdown our socket shutdown(mSocket, SD_SEND); // Close our socket entirely closesocket(mSocket); // Cleanup Winsock WSACleanup(); system("pause"); return 0; }

The message needs to be received by multiple client processes that could be on the same machine or different machines. Im using delphi7, with indy 9.0.18 where im stuck is if i should be using UDP or IP MultiCast or if its even possible... Ive managed to get it to work with IP Multi Cast with one client per machine, but even after many trys with different bindings.. max/min ports etc, i cant seem to find a solution.

  • C#: How to set AsyncWaitHandle in Compact Framework?

    - by Thorsten Dittmar
    Hi, I'm using a TcpClient in one of my Compact Framework 2.0 applications. I want to receive some information from a TCP server. As the Compact Framework does not support the timeout mechanisms of the "large" framework, I'm trying to implement my own timeout-thing. Basically, I want to do the following: IAsyncResult result = client.BeginRead(buffer, 0, size, ..., stream); if (!result.AsyncWaitHandle.WaitOne(5000, false)) // Handle timeout private void ReceiveFinished(IAsyncResult ar) { NetworkStream stream = (NetworkStream)ar.AsyncState; int numBytes = stream.EndRead(ar); // SIGNAL IASYNCRESULT.ASYNCWAITHANDLE HERE ... HOW?? } I'd like to call Set for the IAsyncResult.AsyncWaitHandle, but it doesn't have such a method and I don't know which implementation to cast it to. How do I set the wait handle? Or is it automatically set by calling EndRead? The documentation suggests that I'd have to call Set myself... Thanks for any help!

  • C# inheritance XmlSerializer

    greetngs, i have two classes: [Serializable] public class FireGridUnit { public GridUnit FireGridLocation { get; set; } } [Serializable] public class FireResult: FireGridUnit { public bool Hit { get; set; } public bool ShipDestroyed { get; set; } public Ship.ValidShips DestroyedShipType {get; set;} public bool Win { get; set; } } as you see FireResult inherits FireGrdUnit. in my code when i try to use them i get a runtime error: Unable to cast object of type 'NietzscheBattleships.FireGridUnit' to type 'NietzscheBattleships.FireResult'. is this because if i am serializing the class has to be independant ie not be inherited? many thanks.

  • Using Moq at Blend design time

    - by adrian hara
    This might be a bit out there, but suppose I want to use Moq in a ViewModel to create some design time data, like so: public class SomeViewModel { public SomeViewModel(ISomeDependency dependency) { if (IsInDesignMode) { var mock = new Mock<ISomeDependency>(); dependency = mock.Object; // this throws! } } } The mock could be set up to do some stuff, but you get the idea. My problem is that at design-time in Blend, this code throws an InvalidCastException, with the message along the lines of "Unable to cast object of type 'Castle.Proxies.ISomeDependencyProxy2b3a8f3188284ff0b1129bdf3d50d3fc' to type 'ISomeDependency'." While this doesn't necessarily look to be Moq related but Castle related, I hope the Moq example helps ;) Any idea why that is? Thanks!

  • C#: Semantics for generics?

    - by Rosarch
    I have a list: private readonly IList<IList<GameObjectController>> removeTargets; PickUp inherits from GameObjectController. But when I try this: public IList<PickUp> Inventory // ... gameObjectManager.MoveFromListToWorld(this, user.Model.Inventory); I get a compiler error: cannot convert from 'System.Collections.Generic.IList' to 'System.Collections.Generic.IList' Why does this occur? Shouldn't this be fine, since PickUp is a subclass of GameObjectController? Do I need something like Java's Map<E extends GameObjectController>? Earlier, I was having a similar problem, where I was trying to implicitly cast inventory from an IList to an ICollection. Is this the same problem?

  • How to do regex HTML tag replace in SQL Server?

    - by timmerk
    I have a table in SQL Server 2005 with hundreds of rows with HTML content. Some of the content has HTML like: <span class=heading-2>Directions</span> where "Directions" changes depending on page name. I need to change all the <span class=heading-2> and </span> tags to <h2> and </h2> tags. I wrote this query to do content changes in the past, but it doesn't work for my current problem because of the ending HTML tag: Update ContentManager Set ContentManager.Content = replace(Cast(ContentManager.Content AS NVARCHAR(Max)), 'old text', 'new text') Does anyone know how I could accomplish the span to h2 replacing purely in T-SQL? Everything I found showed I would have to do CLR integration. Thanks!

  • What is the C# equivalent of this Excel VBA code for Shapes?

    - by code4life
    This is the VBA code for an Excel template, which I'm trying to convert to C# in a VSTO project I'm working on. By the way, it's a VSTO add-in: Dim addedShapes() As Variant ReDim addedShapes(1) addedShapes(1) = aBracket.Name ReDim Preserve addedShapes(UBound(addedShapes) + 1) addedShapes(UBound(addedShapes)) = "unique2" Set tmpShape = Me.Shapes.Range(addedShapes).Group At this point, I'm stumped by the addedShapes(), not sure what this is all about. Update: Matti mentioned that addedShapes() represents a variant array in VBA. So now I'm wondering what the contents of addedShapes() should be. Would this be the correct way to call the Shapes.Range() call in C#? List<string> addedShapes = new List<string>(); ... Shape tmpShape = worksheet.Shapes.get_Range (addedShapes.Cast<object>().ToArray()).Group(); I'd appreciate anyone who's worked with VBA and C# willing to make a comment on my question & problem!

  • _mask and Rails

    So I am trying to get the cancan gem to work with my rails 3 app and I've hit a problem. I tried to copy the code that Ryan Bates (the creator of the gem) used in his screen cast, but I get an error saying that roles_mask is not a method. I figure that the _mask method was removed from Ruby/Rails at some point, and I'm now wondering what is the replacement.

  • Using URL Routing for Web Forms with .ashx files

    - by RandomBen
    I am developing a .NET 3.5 Web Forms based website that uses URL Routing. So far I have created a few routes and I have had no issue. I now have a .ashx file that is going to handle sending .pdf files from a table in SQL Server to the website when someone clicks on a link. Normally when I create a Handler it would look like this: return BuildManager.CreateInstanceFromVirtualPath("~/ViewItem.aspx", typeof(Page)) as Page; For my .ashx file I tried: return BuildManager.CreateInstanceFromVirtualPath("~/FileServer.ashx", typeof(Page)) as Page; This doesn't work though because fileserver.ashx is not a page so casting it as typeof(Page)) as Page is going to fail. What do I cast the VirtualPath as instead of Page or is there some other way I should be doing this.

Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Custom initialization } return self; } */ - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } /* // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } */ /* // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return (interfaceOrientation == UIInterfaceOrientationPortrait); } */ - (void)drawRect:(CGRect)rect { CGContextRef ctx = UIGraphicsGetCurrentContext(); CGContextClearRect(ctx, rect); //CGContextSetCMYKFillColor(ctx, 35.0, 56.0, 34.0, 30.0, 1.0); //CGContextSetRGBFillColor(ctx, 92.0f, 95.0f, 97.0f, 1.0f); //CGContextFillRect(ctx, CGRectMake(0, 0, 300, 280)); CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextSetLineWidth(ctx, 2.0); float fltX1,fltX2,fltY1,fltY2=0; NSArray *hoursInDays = [[NSArray alloc] initWithObjects:@"0",@"1" ,@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"11",@"12", nil]; fltX1 = 30; fltY1 = 5; fltX2 = fltX1; fltY2 = 270; //Dividing the Y-axis CGContextMoveToPoint(ctx, fltX1, fltY1); CGContextAddLineToPoint(ctx, fltX2, fltY2); //float y = 275; for(int intIndex = 0 ; intIndex < [hoursInDays count] ; fltY2-=20, intIndex++) { CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextMoveToPoint(ctx, fltX1-3 , fltY2); CGContextAddLineToPoint(ctx, fltX1+3, fltY2); CGContextSelectFont(ctx, "Helvetica", 14.0, kCGEncodingMacRoman); CGContextSetTextDrawingMode(ctx, kCGTextFill); CGContextSetRGBFillColor(ctx, 0, 255, 255, 1); CGAffineTransform xform = CGAffineTransformMake( 1.0, 0.0, 0.0, -1.0, 0.0, 0.0); CGContextSetTextMatrix(ctx, xform); const char *arrayDataForYAxis = [[hoursInDays objectAtIndex:intIndex] UTF8String]; CGContextShowTextAtPoint(ctx, fltX1-18, fltY2-18 , arrayDataForYAxis, strlen(arrayDataForYAxis)); CGContextStrokePath(ctx); } CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextSetLineWidth(ctx, 2.0); fltX1 = 5; fltY1 = 250; fltX2 = 270; fltY2 = fltY1; NSArray *weekDays =[[NSArray alloc] initWithObjects:@"Sun", @"Mon", @"Tus", @"Wed", @"Thu", @"Fri", @"Sat", nil]; //Dividing the X-axis CGContextMoveToPoint(ctx, fltX1, fltY1); CGContextAddLineToPoint(ctx, fltX2, fltY2); //float y = 275; for(int intIndex = 0 ; intIndex < [weekDays count] ; fltX1+=33, intIndex++) { CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextMoveToPoint(ctx, fltX1+52 , fltY2-3); CGContextAddLineToPoint(ctx, fltX1+52, fltY2+3); CGContextSelectFont(ctx, "Arial", 15.0, kCGEncodingMacRoman); CGContextSetTextDrawingMode(ctx, kCGTextFill); CGContextSetRGBFillColor(ctx, 0, 255, 255, 1); CGAffineTransform xform = CGAffineTransformMake( 1.0, 0.0, 0.0, -1.0, 0.0, 0.0); CGContextSetTextMatrix(ctx, xform); const char *arrayDataForXAxis = [[weekDays objectAtIndex:intIndex] UTF8String]; CGContextShowTextAtPoint(ctx, fltX1+37, fltY2+18 , arrayDataForXAxis, strlen(arrayDataForXAxis)); CGContextStrokePath(ctx); } } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview.

  • NoSuchPortException using RXTX Java library on Windows?

    - by Steve
    I have followed the instructions to setup rxtx on windows from http://www.jcontrol.org/download/readme_rxtx_en.html. What I did exactly was copy rxtxSerial.dll to "C:\Program Files\Java\jdk1.6.0_07\jre\bin" and copied RXTXcomm.jar to "C:\Program Files\Java\jdk1.6.0_07\jre\lib\ext" (my JAVA_HOME variable is set to C:\Program Files\Java\jdk1.6.0_07\jre) I also added RXTXcomm.jar to my eclipse project. But when I run it, it still says "NoSuchPortException" Devel Library ========================================= Native lib Version = RXTX-2.0-7pre1 Java lib Version = RXTX-2.0-7pre1 java.lang.ClassCastException: gnu.io.RXTXCommDriver cannot be cast to gnu.io.CommDriver thrown while loading gnu.io.RXTXCommDriver gnu.io.NoSuchPortException at gnu.io.CommPortIdentifier.getPortIdentifier(CommPortIdentifier.java:218) at TwoWaySerialComm.connect(TwoWaySerialComm.java:20) at TwoWaySerialComm.main(TwoWaySerialComm.java:107) In my java file, I tell it: try { (new TwoWaySerialComm()).connect("COM4"); } and I've also tried the Java Comm API. Both cannot recognize my serial port but I am sure I followed the instruction correctly. There files are there. Does anybody have any idea what it could be?

  • Atomic INSERT/SELECT in HSQLDB

    - by PartlyCloudy
    Hello, I have the following hsqldb table, in which I map UUIDs to auto incremented IDs: SHORT_ID (BIG INT, PK, auto incremented) | UUID (VARCHAR, unique) Create command: CREATE TABLE table (SHORT_ID BIGINT GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY, UUID VARCHAR(36) UNIQUE) In order to add new pairs concurrently, I want to use the atomic MERGE INTO statement. So my (prepared) statement looks like this: MERGE INTO table USING (VALUES(CAST(? AS VARCHAR(36)))) AS v(x) ON ID_MAP.UUID = v.x WHEN NOT MATCHED THEN INSERT VALUES v.x When I execute the statement (setting the placeholder correctly), I always get a Caused by: org.hsqldb.HsqlException: row column count mismatch Could you please give me a hint, what is going wrong here? Thanks in advance.

  • Java - short and casting

    - by chr1s
    Hi all, I have the following code snippet. public static void main(String[] args) { short a = 4; short b = 5; short c = 5 + 4; short d = a; short e = a + b; // does not compile (expression treated as int) short z = 32767; short z_ = 32768; // does not compile (out of range) test(a); test(7); // does not compile (not applicable for arg int) } public static void test(short x) { } Is the following summary correct (with regard to only the example above using short)? direct initializations without casting is only possible using literals or single variables (as long as the value is in the range of the declared type) if the rhs of an assignment deals with expressions using variables, casting is necessary But why exactly do I need to cast the argument of the second method call taking into account the previous summary?

  • EXC_BAD_ACCESS in CFAttributedStringSetAttribute and NSNumber?

    - by RichardR
    Hi all, I am getting an infuriating EXC_BAD_ACCESS error in an objective c app I am working on. Any help you could offer would be much appreciated. I have tried the normal debug methods for this error (turning on NSZombieEnabled, checking retain/release/autorelease to make sure I'm not trying to access a deallocated object, etc.) and it hasn't seemed to help. Basically, the error always occurs in this function: ` void op_TJ(CGPDFScannerRef scanner, void *info) { PDFPage *self = info; CGPDFArrayRef array; NSMutableString *tempString = [NSMutableString stringWithCapacity:1]; NSMutableArray *kernArray = [[NSMutableArray alloc] initWithCapacity:1]; if(!CGPDFScannerPopArray(scanner, &array)) { [kernArray release]; return; } for(size_t n = 0; n < CGPDFArrayGetCount(array); n += 2) { if(n >= CGPDFArrayGetCount(array)) continue; CGPDFStringRef pdfString; // if we get a PDF string if (CGPDFArrayGetString(array, n, &pdfString)) { //get the actual string const unsigned char *charstring = CGPDFStringGetBytePtr(pdfString); //add this string to our temp string [tempString appendString:[NSString stringWithCString:(const char*)charstring encoding:[self pageEncoding]]]; //NSLog(@"string: %@", tempString); //get the space after this string CGPDFReal r = 0; if (n+1 < CGPDFArrayGetCount(array)) { CGPDFArrayGetNumber(array, n+1, &r); // multiply by the font size CGFloat k = r; k = -k/1000 * self.tmatrix.a * self.fontSize; CGFloat kKern = self.kern * self.tmatrix.a; k = k + kKern; // add the location and kern to the array NSNumber *tempKern = [NSNumber numberWithFloat:k]; NSLog(@"tempKern address: %p", tempKern); [kernArray addObject:[NSArray arrayWithObjects:[NSNumber numberWithInt:[tempString length] - 1], tempKern, nil]]; } } } // create an attribute string CFMutableAttributedStringRef attString = CFAttributedStringCreateMutable(kCFAllocatorDefault, 10); CFAttributedStringReplaceString(attString, CFRangeMake(0, 0), (CFStringRef)tempString); //apply overall kerning NSNumber *tkern = [NSNumber numberWithFloat:self.kern * self.tmatrix.a * self.fontSize]; CFAttributedStringSetAttribute(attString, CFRangeMake(0, CFAttributedStringGetLength(attString)), kCTKernAttributeName, (CFNumberRef)tkern); //apply individual kern attributes for (NSArray *kernLoc in kernArray) { NSLog(@"kern location: %i, %i", [[kernLoc objectAtIndex:0] intValue],[[kernLoc objectAtIndex:1] floatValue]); CFAttributedStringSetAttribute(attString, CFRangeMake([[kernLoc objectAtIndex:0] intValue], 1), kCTKernAttributeName, (CFNumberRef)[kernLoc objectAtIndex:1]); } CFAttributedStringReplaceAttributedString([self cfAttString], CFRangeMake(CFAttributedStringGetLength([self cfAttString]), 0), attString); //release CFRelease(attString); [kernArray release]; } ` The program always crashes because of line CFAttributedStringSetAttribute(attString, CFRangeMake([[kernLoc objectAtIndex:0] intValue], 1), kCTKernAttributeName, (CFNumberRef)[kernLoc objectAtIndex:1]) And it seems to depend on a few things: if [kernLoc objectAtIndex:1] refers to an [NSNumber numberWithFloat:k] where k = 0 (in other words, if k = 0 above where I populate kernArray) then the program crashes almost immediately If I comment out the line k = k + kKern, it takes longer for the program to crash, but does eventually (why would the crash depend on this value?) If I change the length of CFRangeMake from 1 to 0, it takes a lot longer for the program to crash, but still eventually does. (I don't think I am trying to access beyond the bounds of attString, but am I missing something?) When it crashes, I get something similar to: #0 0x942c7ed7 in objc_msgSend () #1 0x00000013 in ?? () #2 0x0285b827 in CFAttributedStringSetAttribute () #3 0x0000568f in op_TJ (scanner=0x472a590, info=0x4a32320) at /Users/Richard/Desktop/AppTest/PDFHighlight 2/PDFScannerOperators.m:251 Any ideas? It seems like somewhere along the way I am overwriting memory or trying to access memory that has been changed, but I have no idea. If there's anymore information I can provide, please let me know. Thanks, Richard

  • Labeling connections using Oracle Universal Connection Pool (UCP) doesn't seem to work

    - by sapporo
    I'm evaluating the Oracle Universal Connection Pool (UCP) included with their 11.2 JDBC driver, but cannot get the labeling functionality to work properly (which I'd like to use to minimize the amount of ALTER SESSION statements). I'm basically following their sample code to implement the ConnectionLabelingCallback interface. The callback method cost(Properties reqLabels, Properties currentLabels) is called as expected, so the callback seems to be configured correctly. However, the other callback method configure(Properties reqLabels, Object conn) is passed arguments that make it impossible to provide a meaningful implementation: reqLabels is always null, so the callback method has no way of knowing what labels need to be set. conn is of type oracle.jdbc.driver.T4CConnection, which cannot be cast to LabelableConnection, so the callback method has no way of inspecting or manipulating the labels attached to the connection. My code is running on Java 6 and using ojdbc6.jar and ucp.jar version 11.2.0.1.0. The database is actually 10.2, but that should not be a problem according to the docs, since the UCP functionality is completely implemented in the JDBC driver. Thanks in advance!
