• How to make Fluent NHibernate ignore Dictionary properties

  - by Matt Winckler

  I'm trying to make Fluent NHibernate's automapping ignore a Dictionary property on one of my classes, but Fluent is ignoring me instead. Ignoring other types of properties seems to work fine, but even after following the documentation and adding an override for the Dictionary, I still get the following exception when BuildSessionFactory is called: The type or method has 2 generic parameter(s), but 1 generic argument(s) were provided. A generic argument must be provided for each generic parameter. I've tried overriding by property name: .Override<MyClass>(map => { map.IgnoreProperty(x => x.MyDictionaryProperty); }) and also tried implementing ignores using a custom attribute, both of which result in the same exception from BuildSessionFactory. The only thing so far that makes this exception go away is removing the Dictionary property entirely. My question seems to be identical to this one which was never answered (though I'll expand the scope by stating it doesn't matter whether the dictionary is on an abstract base class; the problem always happens for me regardless of what class the property is on). Any takers this time around?

• JDK-7 SwingWorker deadlocks?

  - by kd304

  I have a small image processing application which does multiple things at once using SwingWorker. However, if I run the following code (oversimplified excerpt), it just hangs on JDK 7 b70 (windows) but works in 6u16. It starts a new worker within another worker and waits for its result (the real app runs multiple sub-workers and waits for all this way). Did I use some wrong patterns here (as mostly there is 3-5 workers in the swingworker-pool, which has limit of 10 I think)? import javax.swing.SwingUtilities; import javax.swing.SwingWorker; public class Swing { static SwingWorker<String, Void> getWorker2() { return new SwingWorker<String, Void>() { @Override protected String doInBackground() throws Exception { return "Hello World"; } }; } static void runWorker() { SwingWorker<String, Void> worker = new SwingWorker<String, Void>() { @Override protected String doInBackground() throws Exception { SwingWorker<String, Void> sw2 = getWorker2(); sw2.execute(); return sw2.get(); } }; worker.execute(); try { System.out.println(worker.get()); } catch (Exception e) { e.printStackTrace(); } } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { runWorker(); } }); } }

• Error mounting CloudDrive snapshot in Azure

  - by Dave

  Hi, I've been running a cloud drive snapshot in dev for a while now with no probs. I'm now trying to get this working in Azure. I can't for the life of me get it to work. This is my latest error: Microsoft.WindowsAzure.Storage.CloudDriveException: Unknown Error HRESULT=D000000D ---> Microsoft.Window.CloudDrive.Interop.InteropCloudDriveException: Exception of type 'Microsoft.WindowsAzure.CloudDrive.Interop.InteropCloudDriveException' was thrown. at ThrowIfFailed(UInt32 hr) at Microsoft.WindowsAzure.CloudDrive.Interop.InteropCloudDrive.Mount(String url, SignatureCallBack sign, String mount, Int32 cacheSize, UInt32 flags) at Microsoft.WindowsAzure.StorageClient.CloudDrive.Mount(Int32 cacheSize, DriveMountOptions options) Any idea what is causing this? I'm running both the WorkerRole and Storage in Azure so it's nothing to do with the dev simulation environment disconnect. This is my code to mount the snapshot: CloudDrive.InitializeCache(localPath.TrimEnd('\\'), size); var container = _blobStorage.GetContainerReference(containerName); var blob = container.GetPageBlobReference(driveName); CloudDrive cloudDrive = _cloudStorageAccount.CreateCloudDrive(blob.Uri.AbsoluteUri); string snapshotUri; try { snapshotUri = cloudDrive.Snapshot().AbsoluteUri; Log.Info("CloudDrive Snapshot = '{0}'", snapshotUri); } catch (Exception ex) { throw new InvalidCloudDriveException(string.Format( "An exception has been thrown trying to create the CloudDrive '{0}'. This may be because it doesn't exist.", cloudDrive.Uri.AbsoluteUri), ex); } cloudDrive = _cloudStorageAccount.CreateCloudDrive(snapshotUri); Log.Info("CloudDrive created: {0}", snapshotUri, cloudDrive); string driveLetter = cloudDrive.Mount(size, DriveMountOptions.None); The .Mount() method at the end is what's now failing. Please help as this has me royally stumped! Thanks in advance. Dave

• How to assign Image Uri in a custom Control.

  - by Subhen

  Hi, I want to place an image inside my custom control , so my generic.xaml looks like below: <Style TargetType="local:generic"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="local:generic"> <Grid Background="{TemplateBinding Background}"> <Rectangle> <Rectangle.Fill> <SolidColorBrush x:Name="BackgroundBrush" Opacity="0" /> </Rectangle.Fill> </Rectangle> <TextBlock Text="{TemplateBinding Text}" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="{TemplateBinding Foreground}"/> <Image Source="{TemplateBinding Source}" HorizontalAlignment="Center" VerticalAlignment="Center"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> My Codebehind is as follows: public class Generic : Control { public static DependencyProperty ImageUri = DependencyProperty.Register("Source", typeof(Uri), typeof(generic), new PropertyMetadata("")); public Uri Source { get { return (Uri)GetValue(generic.ImageUri); } set { SetValue(generic.ImageUri, value); } } public generic() { this.DefaultStyleKey = typeof(generic); } } Apllication is compiling fine but while I am trying to run it throws the following exception : $exception {System.Windows.Markup.XamlParseException: System.TypeInitializationException: The type initializer for 'testCstmCntrl.themes.generic' threw an exception. ---> System.ArgumentException: Default value type does not match type of property.

• Rebinding and singleton-behaviour [NInject]

  - by Maximilian Csuk

  Hi! I have set up a NInject (using version 1.5) binding like this: Bind<ISessionFactory>().ToMethod<ISessionFactory>(ctx => { try { // create session factory, might fail because of database issues like wrong connection string } catch (Exception e) { throw new DatabaseException(e); } }).Using<SingletonBehavior>(); As you can see, this binding uses a singleton behavior but can also throw exception when something is not configured correctly, like a wrong connection string to the database. Now, when the creation of a session factory fails at first (throwing a database exception), NInject doesn't try to create the object again but always returns null. I would need NInject to check for null first and recreate when the instance is null, but of course not when there already is an instance successfully constructed (keeping it singleton). Like this: var a = Kernel.Get<ISessionFactory>(); // might fail, a = null // ... change some database settings var b = Kernel.Get<ISessionFactory>(); // might not fail anymore, b = ISessionFactory object Would I need to write a custom behavior or am I missing something else? Thanks for your answers!

• Word 2007 COM - Can't directly access a page when word is set to invisible

  - by Robbie

  I'm using Word 2007 via COM from PHP 5.2 Apache 2.0 on a windows machine. The goal is to programmatically render jpeg thumbnails from each page in a Word document. The following code works correctly if you set $word-Visible to 1: try { $word = new COM('word.application'); $word->Visible = 0; $word->Documents->Open("C:\\test.doc"); echo "Number of pages: " . $word->ActiveDocument->ActiveWindow->ActivePane->Pages->Count() . "</br>"; $i = 1; foreach ($word->ActiveDocument->ActiveWindow->ActivePane->Pages as $page) { echo "Page number: $i </br>"; $i++; } //get the EMF image of the page $data = $word->ActiveDocument->ActiveWindow->ActivePane->Pages->Item(3)->EnhMetaFileBits; $word->ActiveDocument->Close(); $word->Quit(); } catch (Exception $e) { echo "Exception: " .$e->getMessage(); } The test document I'm using contains 35 pages. The code will display the correct number of pages but the for each loop only loops over 1 page. I can only directly access page 1 and 2 in the Pages-Item() collection. If I try to access another page I get the exception: "The requested member of the collection does not exist." If I set the $word-Visible property to 1 I do get all the pages in the foreach loop and I can access any page directly. Everything is working as expected if Word is set to be visible. Even stranger is the fact that if I set Word to be invisible and I don't have the foreach loop I can only access page 1 instead of page 1 and 2 if I do the for each loop. Any pointers on how I can access all the pages in the document and keeping word invisible?

The application is an intranet app, and I have programmatically set the bindings on both the service and the client as: NetTcpBinding aBinding = new NetTcpBinding(SecurityMode.Transport); aBinding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows; aBinding.Security.Transport.ProtectionLevel = System.Net.Security.ProtectionLevel.EncryptAndSign; Both the service and client have endpoints configured with SPNs: EndpointAddress = new EndpointAddress(uri, EndpointIdentity.CreateSpnIdentity("Service1")); As far as I know, I have setup the bindings correctly-- and I am usually able to connect to the service just fine. I did however run into a case where on a server running Windows Server 2003 R2, x64, SP2 I get the following exception immediately when the client tries to connect: INNEREXCEPTION -- Exception Message: InvalidCredentialException: Either the target name is incorrect or the server has rejected the client credentials. Stack Trace: at System.Net.Security.NegoState.ProcessAuthentication(LazyAsyncResult lazyResult) at System.Net.Security.NegotiateStream.AuthenticateAsClient(NetworkCredential credential, String targetName, ProtectionLevel requiredProtectionLevel, TokenImpersonationLevel allowedImpersonationLevel) at System.ServiceModel.Channels.WindowsStreamSecurityUpgradeProvider.WindowsStreamSecurityUpgradeInitiator.OnInitiateUpgrade(Stream stream, SecurityMessageProperty& remoteSecurity) I get the exception when I try to connect to the service from another machine in the domain, but if I connect to the service on the same machine running the service it works fine. The hosting service itself is running as a domain user account-- but I have tried running the service as a Local System and Network Service to no avail. I have checked the Local Security Policies for the server and didn't see anything amiss (i.e. 'Access this computer from the network' includes 'Everyone'). Anyone have an idea of what could resolve this? I am wondering if I need to do something in Active Directory with respect to the service's SPN? I have read some about using setspn.exe to register or refresh SPNs, but I haven't needed to do this before. Why would this be working with other configurations but not the one above?

• Groovy on Grails: GORM and BitSets?

  I don't see anything in the official documentation about unsupported persistence data types, so I'm working under the assumption that types available in the Groovy language should be handled.

• Web Service Client in JBOSS 5.1 with JDK6

  - by dcp

  This is a continuation of the question here: http://stackoverflow.com/questions/2435286/jboss-does-app-have-to-be-compiled-under-same-jdk-as-jboss-is-running-under It's different enough though that it required a new question. I am trying to use jdk6 to run JBOSS 5.1, and I downloaded the JDK6 version of JBOSS 5.1. This works fine and my EAR application deploys fine. However, when I want to run a web service client with code like this: public static void main(String[] args) throws Exception { System.out.println("creating the web service client..."); TestClient client = new TestClient("http://localhost:8080/tc_test_project-tc_test_project/TestBean?wsdl"); Test service = client.getTestPort(); System.out.println("calling service.retrieveAll() using the service client"); List<TestEntity> list = service.retrieveAll(); System.out.println("the number of elements in list retrieved using the client is " + list.size()); } I get the following exception: javax.xml.ws.WebServiceException: java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage at org.jboss.ws.core.jaxws.client.ClientImpl.handleRemoteException(ClientImpl.java:396) at org.jboss.ws.core.jaxws.client.ClientImpl.invoke(ClientImpl.java:302) at org.jboss.ws.core.jaxws.client.ClientProxy.invoke(ClientProxy.java:170) at org.jboss.ws.core.jaxws.client.ClientProxy.invoke(ClientProxy.java:150) Now, here's the really interesting part. If I change the JDK that my the code above is running under from JDK6 to JDK5, the exception above goes away! It's really strange. The only way I found for the code above to run under JDK6 was to take the JBOSS_HOME/lib/endorsed folder and copy it to JDK6_HOME/lib. This seems like it shouldn't be necessary, but it is. Is there any other way to make this work other than using the workaround I just described?

• How to synchronize placing an object in JNDI across processes?

  - by indra

  I am trying to place an object in JNDI, so that only one of the progam should be able to place it in JNDI. is there any global lock that can be used in J2EE environment. Is RMI can be used for this purpose? please provide any reference links. Thanks in advance. Also, what is NameAlreadyBoundexception? I am trying to use it as a method to synchronize, i.e, only one program places it in JNDI and if other trying to bind should get that exception. But when i am testing the multiple binding I am not getting the Exception.And second binding is done. look up is giving the second object bound. here is my code: private static String JNDI_NAME = "java:comp/env/test/something"; public class TestJNDI { private static String JNDI_NAME = "java:comp/env/test/something"; public static void main(String[] args) throws NamingException { Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory"); env.put(Context.PROVIDER_URL,"t3://127.0.0.1:7001"); Context ctx = new InitialContext(env); System.out.println("Initial Context created"); String obj1 = "obj1"; String obj2 = "obj2"; try{ ctx.bind(JNDI_NAME, obj1); System.out.println("Bind Sucess"); }catch(NameAlreadyBoundException ne ){ // already bound System.out.println("Name already bound"); } ctx.close(); Context ctx2 = new InitialContext(env); try{ // Second binding to the same name not giving the Exception?? ctx2.bind(JNDI_NAME, obj2); System.out.println("Re Bind Sucess"); }catch(NameAlreadyBoundException ne ){ // already bound System.out.println("Name already bound"); } String lookedUp = (String) ctx2.lookup(JNDI_NAME); System.out.println("LookedUp Object"+lookedUp); ctx2.close(); } }

• .NET Sockets Buffer Overflow No Error

  - by Michael Covelli

  I have one thread that is receiving data over a socket like this: while (sock.Connected) { // Receive Data (Block if no data) recvn = sock.Receive(recvb, 0, rlen, SocketFlags.None, out serr); if (recvn <= 0 || sock == null || !sock.Connected) { OnError("Error In Receive, recvn <= 0 || sock == null || !sock.Connected"); return; } else if (serr != SocketError.Success) { OnError("Error In Receive, serr = " + serr); return; } // Copy Data Into Tokenizer tknz.Read(recvb, recvn); // Parse Data while (tknz.MoveToNext()) { try { ParseMessageAndRaiseEvents(tknz.Buffer(), tknz.Length); } catch (System.Exception ex) { string BadMessage = ByteArrayToStringClean(tknz.Buffer(), tknz.Length); string msg = string.Format("Exception in MDWrapper Parsing Message, Ex = {0}, Msg = {1}", ex.Message, BadMessage); OnError(msg); } } } And I kept seeing occasional errors in my parsing function indicating that the message wasn't valid. At first, I thought that my tokenizer class was broken. But after logging all the incoming bytes to the tokenizer, it turns out that the raw bytes in recvb weren't a valid message. I didn't think that corrupted data like this was possible with a tcp data stream. I figured it had to be some type of buffer overflow so I set sock.ReceiveBufferSize = 1024 * 1024 * 8; and the parsing error never, ever occurs in testing (it happens often enough to replicate if I don't change the ReceiveBufferSize). But my question is: why wasn't I seeing an exception or an error state or something if the socket's internal buffer was overflowing before I changed this buffer size?

• use of assertions for type checking in php?

  - by user151841

  I do some checking of arguments in my classes in php using exception-throwing functions. I have functions that do a basic check ( ===, in_array etc ) and throw an exception on false. So I can do assertNumeric($argument, "\$argument is not numeric."); instead of if ( ! is_numeric($argument) ) { throw new Exception("\$argument is not numeric."); } Saves some typing I was reading in the comments of the php manual page on assert() that As noted on Wikipedia - "assertions are primarily a development tool, they are often disabled when a program is released to the public." and "Assertions should be used to document logically impossible situations and discover programming errors— if the 'impossible' occurs, then something fundamental is clearly wrong. This is distinct from error handling: most error conditions are possible, although some may be extremely unlikely to occur in practice. Using assertions as a general-purpose error handling mechanism is usually unwise: assertions do not allow for graceful recovery from errors, and an assertion failure will often halt the program's execution abruptly. Assertions also do not display a user-friendly error message." This means that the advice given by "gk at proliberty dot com" to force assertions to be enabled, even when they have been disabled manually, goes against best practices of only using them as a development tool So, am I 'doing it wrong'? What other/better ways of doing this are there?

• Why do IOExceptions occur in ReadableByteChannel.read()

  - by Steffen Heil

  Hi The specification of ReadableByteChannel.read() shows -1 as result value for end-of-stream. Moreover it specifies ClosedByInterruptExceptionas possible result if the thread is interrupted. Now I thought that would be all - and it is most of the time. However, now and then I get the following: java.io.IOException: Eine vorhandene Verbindung wurde vom Remotehost geschlossen at sun.nio.ch.SocketDispatcher.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:25) at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:233) at sun.nio.ch.IOUtil.read(IOUtil.java:206) at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:236) at ... I do not unterstand why I don't get -1 in this case. Also this is not a clean exception, as I cannot catch it without catching any possible IOException. So here are my questions: Why is this exception thrown in the first place? Is it safe to assume that ANY exception thrown by read are about the socket being closed? Is all this the same for write()? And by the way: If I call SocketChannel.close() do I have to call SocketChannel.socket().close() as well or is this implied by the earlier? Thanks, Steffen

• Can FluentNHibernate be used with .Net4?

  - by stiank81

  I have a WPF application running with .Net3.5 using FluentNHibernate, and all works fine. When I upgraded to VS2010 I ran into some odd problems, but after changing to use x64 variant of SQLite it worked fine again. Now I want to change to use .Net4, but this has turned into a more painful experience then I expected.. First I met a problem which required that I set a [SecurityCritical] attribute. Fine - I fixed this. But the reason this was exposed was because an exception was thrown in the first place. And the exception thrown was the following - when calling FluentConfiguration.BuildConfiguration: FluentConfigurationException unhandled An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail The inner exception gives us more information: Message = "Could not create the driver from NHibernate.Driver.SQLite20Driver, NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4." This is what I saw in my own project when moving to VS2010. I have tried changing Fluent to use the x64 variant of SQLite, but this doesn't change anything. Does it sound like it might be related to mixing of 32bit and 64bit assemblies? I see that there are also others that have seen this problem, but I haven't really seen any solution yet. Anyone out there using Fluent with .Net4 and SQLite - on a 64bit machine - successfully? Help! I'm lost...

• Why is my GZipStream not writeable?

  - by Ozzah

  I have some GZ compressed resources in my program and I need to be able to write them out to temporary files for use. I wrote the following function to write the files out and return true on success or false on failure. In addition, I've put a try/catch in there which shows a MessageBox in the event of an error: private static bool extractCompressedResource(byte[] resource, string path) { try { using (MemoryStream ms = new MemoryStream(resource)) { using (FileStream fs = new FileStream(path, FileMode.Create, FileAccess.ReadWrite)) { using (GZipStream zs = new GZipStream(fs, CompressionMode.Decompress)) { ms.CopyTo(zs); // Throws exception zs.Close(); ms.Close(); } } } } catch (Exception ex) { MessageBox.Show(ex.Message); // Stream is not writeable return false; } return true; } I've put a comment on the line which throws the exception. If I put a breakpoint on that line and take a look inside the GZipStream then I can see that it's not writeable (which is what's causing the problem). Am I doing something wrong, or is this a limitation of the GZipStream class?
