  • Mat matrix multiplication, openCV?

    - by facebook-1593205594
    I initialized two Mat images as: Mat ft=Mat::zeros(src.rows,src.cols,CV_32FC1),h=Mat::zeros(src.rows,src.cols,CV_32FC1); and then i have some calculations: ft has fourier transform stored for an image, and h has matrix for Laplacian filtering in fourier domain.......they both have same dimensions, and then i did multiplication of them using both h*ft and gemm(h,ft,1,NULL,0,temp); function call but while executing it shows some problems..... it reads like this: opencv error assertion failed (some long code and at last says something about gemm in ....matmul.cpp)......termination called after throwing exception of 'cv::exception'

  • Element 'Chart' is not a known element - dotnetCHARTING

    - by Ryan
    Hi, I am using dotnetCHARTING: the dll is installed in the GAC and referenced in my web.config (all versions appear to match). The project has a reference to the dll. web.config: <add assembly="dotnetCHARTING, Version=5.3.3540.17054, Culture=neutral, PublicKeyToken=af2cd47db69d93bd"/> The site code compiles ok, but all aspx pages using the charting library complain that the Chart tag does not exist (warning that it might be a compile error). The aspx pages do not render the charts. Each page has a reference to the assembly: <%@ Register Assembly="dotnetCHARTING" Namespace="dotnetCHARTING" TagPrefix="dotnetCHARTING" %> Does anybody know what could be causing this? Thanks a lot for any help - I'm quite desperate to get this resolved. Ryan

  • Problem to display a pdf from my JSF Portlet of Liferay

    - by Stefano
    I use liferay 5.2 with jsf-portlet. From the page I want to press a button to generate one PDF. In managedbean i build pdf and I want to show it in response. In a ByteArrayOutputStream named outputStream i have my pdf built with JasperReport. I write: PortletResponse portletResponse = (PortletResponse)externalCtx.getResponse(); HttpServletResponse httpResponse = PortalUtil.getHttpServletResponse(portletResponse); ServletOutputStream out = httpResponse.getOutputStream(); String filename="Pdf" + System.currentTimeMillis()+".pdf"; httpResponse.reset(); httpResponse.setContentType("application/pdf"); httpResponse.setHeader("Content-Disposition", "attachment; filename=\""+ filename + "\""); httpResponse.setContentLength(outputStream.size()); outputStream.writeTo(out); out.flush(); out.close(); I do not see anything output! In jboss log i read: IllegaStateException.... What is wrong?

  • subsonic in visual studio design host

    - by csizo
    Hi, I'm facing currently a problem regarding Subsonic configuration. What I want to achieve is using subsonic data access in a System.Web.UI.Design.ControlDesigner class. This class is hosted in Visual Studio Environment and enables design time operations on the attached System.Web.UI.WebControls.Control. The only problem is SubSonic seems always looking for SubSonicSection in the application configuration regardless passing connection string to it. The relevant code snippet: using (SharedDbConnectionScope dbScope = new SharedDbConnectionScope(new SqlDataProvider(), ConnectionString)) { Table1 _table1 = new Select().From<..().Where(...).IsEqualTo(...).ExecuteSingle<...>(); Throws exception on ExecuteSingle() method (configuration section was not found) while using (SharedDbConnectionScope dbScope = new SharedDbConnectionScope(ConnectionString)) { Throws exception on new SharedDbConnectionScope() (configuration section was not found) So the question is: Is there any way to pass the settings runtime to bypass the configuration section lookup as I don't want to add any subsonic specific configuration to devenv.configuration Thanks

  • Index was outside the bounds of the array. IndexOutOfRangeException in LINQ to SQL

    - by gtas
    Im getting this exception in the protected virtual void SendPropertyChanged(String propertyName) { if ((this.PropertyChanged != null)) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); <---- HERE !!! } } of one recently table association i created, there lots of same associations around the database, and this happened in the 4 specific tables i added. Its 1...* relationship and association is Primary Table - Id (identity auto generated) Foreign PId column int not null. I just dont get it....Im using SqlMetal for generation, i regenerated the schema, rebuild, same. This is causing while inserting row in DevExpress XtraGrid, but i dont think this should be issue, same control with same functionality but for different tables works ok. I use grid's event for append value in a property when the entity creating. I disabled this but same again. Recreated the association. No change, exception occurs. Any ideas?

  • Is this good C# style?

    - by burnt1ce
    Consider the following method signature: public static bool TryGetPolls(out List<Poll> polls, out string errorMessage) This method performs the following: accesses the database to generate a list of Poll objects. returns true if it was success and errorMessage will be an empty string returns false if it was not successful and errorMessage will contain an exception message. Is this good style? Update: Lets say i do use the following method signature: public static List<Poll> GetPolls() and in that method, it doesn't catch any exceptions (so i depend the caller to catch exceptions). How do i dispose and close all the objects that is in the scope of that method? As soon as an exception is thrown, the code that closes and disposes objects in the method is no longer reachable.

  • OleDb database to DataSet and back in c#?

    - by Troy
    I'm writing a program that lets a user: Connect to an (arbitrary) View all of the tables in that database in separate DataGridViews Edit them in the program, generate random data, and see the results Choose to commit those changes or revert So I discovered the DataSet class, which looks like it's capable of holding everything that a database would, and I decided that the best thing to do here would be to load everything into one dataset, let the user edit it, and then save the dataset back to the database. The problem is that the only way I can find to load the database tables is this: set = new DataSet(); DataTable schema = connection.GetOleDbSchemaTable( OleDbSchemaGuid.Tables, new string[] { null, null, null, "TABLE" }); foreach (DataRow row in schema.Rows) { string tableName = row.Field<string>("TABLE_NAME"); DataTable dTable = new DataTable(); new OleDbDataAdapter("SELECT * FROM " + tableName, connection).Fill(dTable); dTable.TableName = tableName; set.Tables.Add(dTable); } while it seems like there should be a simpler way given that datasets appear to be designed for exactly this purpose. The real problem though is when I try saving these things. In order to use the OleDbDataAdapter.Update() method, I'm told that I have to provide valid INSERT queries. Doesn't that kind of negate the whole point of having a class to handle this stuff for me? Anyway, I'm hoping somebody can either explain how to load and save a database into a dataset or maybe give me a better idea of how to do what I'm trying to do. I could always parse the commands together myself, but that doesn't seem like the best solution.

  • Javassist annoations problem

    - by Ali
    I'm trying to generate my Entity class using javassist. Everything went well until I added the GeneratedValue annotation to the Id field. The @Id annotation works fine but when I add @GeneeratedValue I get an exception. This is my code: ClassPool cp = ClassPool.getDefault(); CtClass ctClass = cp.makeClass("test.Snake"); ClassFile classFile = ctClass.getClassFile(); classFile.setVersionToJava5(); AnnotationsAttribute attribute = new AnnotationsAttribute(classFile.getConstPool(), AnnotationsAttribute.visibleTag); Annotation idAnnotation = new Annotation(classFile.getConstPool(), ClassPool.getDefault().get("javax.persistence.Id")); attribute.addAnnotation(idAnnotation); Annotation gvAnnotation = new Annotation(classFile.getConstPool(), ClassPool.getDefault().get("javax.persistence.GeneratedValue")); attribute.addAnnotation(gvAnnotation); CtField idField = new CtField(ClassPool.getDefault().get("java.lang.Long"), "id", ctClass); idField.getFieldInfo().addAttribute(attribute); ctClass.addField(idField); CtField nameField = new CtField(ClassPool.getDefault().get("java.lang.String"), "name", ctClass); ctClass.addField(nameField); AnnotationsAttribute attr = new AnnotationsAttribute(classFile.getConstPool(), AnnotationsAttribute.visibleTag); Annotation annotation = new Annotation(classFile.getConstPool(), ClassPool.getDefault().get("javax.persistence.Entity")); attr.addAnnotation(annotation); classFile.addAttribute(attr); snakeClass = ctClass.toClass(); newInstance = snakeClass.newInstance(); And this is the exception I get: java.lang.NullPointerException at javassist.bytecode.ConstPool.getUtf8Info(ConstPool.java:565) at javassist.bytecode.annotation.EnumMemberValue.getValue(EnumMemberValue.java:98) at javassist.bytecode.annotation.EnumMemberValue.write(EnumMemberValue.java:116) at javassist.bytecode.annotation.Annotation.write(Annotation.java:316) at javassist.bytecode.AnnotationsAttribute.setAnnotations(AnnotationsAttribute.java:246) at javassist.bytecode.AnnotationsAttribute.addAnnotation(AnnotationsAttribute.java:211) at ClassLoadingTest.javassitTest(ClassLoadingTest.java:56) It seems to be a problem with @GeneratedValue. When I use it alone whithout id I get this exception either. When I use eclipse debugger to watch variable values, I get get this com.sun.jdi.InvocationException occurred invoking method. instead of the annotation value. but for Id annotation it shows a javassist annotation object. I'm new to javassist. Can anyone help me?

  • Wrapped WPF Control

    - by Robert
    Hi, I'm trying to create a GUI (WPF) Library where each (custom) control basically wraps an internal (third party) control. Then, I'm manually exposing each property (not all of them, but almost). In XAML the resulting control is pretty straightforward: <my:CustomButton Content="ClickMe" /> And the code behind is quite simple as well: public class CustomButton : Control { private MyThirdPartyButton _button = null; static CustomButton() { DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomButton), new FrameworkPropertyMetadata(typeof(CustomButton))); } public CustomButton() { _button = new MyThirdPartyButton(); this.AddVisualChild(_button); } protected override int VisualChildrenCount { get { return _button == null ? 0 : 1; } } protected override Visual GetVisualChild(int index) { if (_button == null) { throw new ArgumentOutOfRangeException(); } return _button; } #region Property: Content public Object Content { get { return GetValue(ContentProperty); } set { SetValue(ContentProperty, value); } } public static readonly DependencyProperty ContentProperty = DependencyProperty.Register( "Content", typeof(Object), typeof(CustomButton), new FrameworkPropertyMetadata(new PropertyChangedCallback(ChangeContent)) ); private static void ChangeContent(DependencyObject source, DependencyPropertyChangedEventArgs e) { (source as CustomButton).UpdateContent(e.NewValue); } private void UpdateContent(Object sel) { _button.Content = sel; } #endregion } The problem comes after we expose MyThirdPartyButton as a property (in case we don't expose something, we would like to give the programmer the means to use it directly). By simply creating the property, like this: public MyThirdPartyButton InternalControl { get { return _button; } set { if (_button != value) { this.RemoveVisualChild(_button); _button = value; this.AddVisualChild(_button); } } } The resulting XAML would be this: <my:CustomButton> <my:CustomButton.InternalControl> <thirdparty:MyThirdPartyButton Content="ClickMe" /> </my:CustomButton.InternalControl> And what I'm looking for, is something like this: <my:CustomButton> <my:CustomButton.InternalControl Content="ClickMe" /> But (with the code I have) its impossible to add attributes to InternalControl... Any ideas/suggestions? Thanks a lot, -- Robert

  • Returning value of static property from public instance property

    - by Jamie Dixon
    I was just playing around with some code in LINQPad and managed to crash the program with a stackoverflow exception. I basically created a static property in a class and used another property to return the value from an instance. The getter of my instance property would return the value of the static property, but the setter would set itself. When would this type of pattern be used and how come it generated a stackoverflow exception? Code example of what I did: void Main() { SomeClass myinstance = new SomeClass(); SomeClass.x = "Some Value"; myinstance.y = "Some other value"; myinstance.y.Dump(); } public class SomeClass { public static string x; public string y { get { return x; } set { y = value; } } }

  • Programatically send SMS to email using Verizon Motorola Droid on Android

    - by Dave
    Hi, I was wondering if anyone knew the proper way to send an SMS message to an e-mail address using Verizon's CDMA Motorola Droid phone. The internal messaging application appears to automagically do this. While 3rd party applications like SMSPopup don't seem to be able to properly reply to e-mail addresses unless you compose the message inside the messaging application. When the internal messaging application sends a SMS message there's a corresponding 'RIL_REQUEST_CDMA_SEND_SMS' entry in the logcat (adb logcat -b radio). When you send a SMS to an e-mail address it prints the same thing, so behind the scenes it looks as though it is sending an sms. The interesting thing is that if you look at the content provider sent box the messages are addressed to various 1270XX-XXX-XXXX numbers. On other services you can send e-mail addresses by sending a SMS to a predefined short sms number. And then formatting your SMS as emailaddress subject message i.e. http://en.wikipedia.org/wiki/SMS_gateway#Carrier-Provided_SMS_to_E-Mail_Gateways For example, using T-mobile's number (500) you can send a SMS to an e-mail using the following: SmsManager smsMgr = SmsManager.getDefault(); smsMgr.sendTextMessage("500", null, "[email protected] message sent to an e-mail address from a SMS", null, null); Does anyone know if It is possible to programatically send SMS to email messages from a CDMA Android phone? Does Verizon actually send your replies as SMS messages or are they actually sent as MMS or normal http email messages? Any ideas about how to intercept what the raw message being sent to see what's going on? It might be possible that Verizon somehow generates a fake number temporarily tied to an e-mail address (since repeated messages are not sent to the same number). But, that seems pretty heavy handed. Thanks!

  • Where can I find a description of the old British Standard structured flow charts?

    - by Steve314
    Some professional organisation defined these in, IIRC, the early 80s as similar to the more well known flow charts, but "structured". Instead of having arbitrary "goto" arrows, they had the equivalent of loops etc. They were standardized, and I vaguely remember studying them briefly at O Level. Of course they were about as useful as the well-known chocolate teapot, but I'd still like to be able to find a reference guide for them if possible - for roughly the same reason I was looking for a reference for standard Basic a while back. Google tells me - well, nothing really. They may as well never have existed. Which is probably nearly (and perhaps completely) true - I certainly never heard of them anywhere else except when I was at school. There's a chance that they may even be my computer science teachers little joke.

  • Riddle with "href".

    - by kalininew
    Mysticism. I use XSLT for reception of the address for the reference. <a href="{element/url}"/> In XML i have: <element> <url>www.mysite.ru</url> </element> As a result on page I receive: <a href="www.currentsite.ru/cursection/cursubsection/www.mysite.ru"/> That is: in the beginning there is an address of a current site (the address of current section where we now are), and then there is a reference to an external site. There can be it any problem with metatag BASE? In what a trouble?

  • AsyncTask, RejectedExecutionException and Task Limit

    - by Samuh
    I am fetching lots of thumbnails from a remote server and displaying them in a grid view, using AsyncTask. The problem is, my grid view displays 20 thumbnails at a time, so that creates 20 AsyncTasks and starts 20 executes, one per thumbnail. I get RejectedExecution exception in my code. I recall reading somewhere that there is a limit to number of tasks that AsyncTask can have in its queue at a time, i might be hitting that. Was this bar lifted? Is there a way to increase this limit? Is it safe to just ignore this exception?(by having an empty catch(RejectedException e){} block?) I am running this code on Android 1.6 emulator and the API level in my code(minSDKVersion is 3). [EDIT: Added SDK and API level info]

  • SDL doesn't detect Arrow Keys

    - by Scott
    I am working through the SDL tutorials over at http://lazyfoo.net/SDL_tutorials/index.php and I'm stuck on tutorial 8 where I'm working with key presses. I'm using the following code: //Our Main application loop while(!quit){ if(SDL_PollEvent(&curEvents)){ if(curEvents.type == SDL_QUIT){ quit = true; } //If a key was pressed if( curEvents.type == SDL_KEYDOWN ) { //Set the proper message surface switch( curEvents.key.keysym.sym ) { case SDLK_UP: message = upMessage; break; case SDLK_DOWN: message = downMessage; break; case SDLK_LEFT: message = leftMessage; break; case SDLK_RIGHT: message = rightMessage; break; default: message = TTF_RenderText_Solid(font, "Unknown Key", textColor); break; } } } if( message != NULL ) { //Apply the background to the screen applySurface( 0, 0, background, screen ); //Apply the message centered on the screen applySurface( ( SCREEN_WIDTH - message->w ) / 2, ( SCREEN_HEIGHT - message->h ) / 2, message, screen ); //Null the surface pointer message = NULL; } //Update the screen if( SDL_Flip( screen ) == -1 ) { return 1; } } Where works fine, the default case is reached, for everything BUT pressing the arrow keys. I was wondering if someone could spot what I'm doing wrong.

  • ajax in zend frame work

    - by rookie
    Hi, I am new to Zend Frame Work. I am using $ajaxContext = $this-_helper-getHelper('AjaxContext'); for adding action contexts. I have one Index.phtml page and all other views are ajax.phtml pages. I have to do some java script methods in the ajax.phtml pages. But i didn't find a way to refer the js files in the ajax.phtml pages. I have tried adding those in the controller init and index action, using $this-view-headScript()-appendFile, though i have the reference added in the page source, none of htese seems to be working on the ajax content. Then i tried to add it in the action for the ajax page, then it is not coming in the page source itself. As far as i understood, $this-view-headScript()-appendFile will append the file reference to the layout page and for the ajax.phtml pages, the layout will be disabled. Is there any way that i can refer my js files in the ajax.phtml pages?

    Hi everybody... I'm developing a asp.net mvc application with nhibernate and I would not like to expose my objects mappings with NHibernate, so I created DTO for each entity and I'm trying to convert my Domain objects to DTO and send it to View. So I have in my sollution: ClassLibrary with my Domain (for NHibernate) and DTO objetcs Class library to make a SessionFactory adn Factories in my Project Asp.Net MVC 2 Application So, I download AutoMapper to transform Domain objects in DTO and add a the code to do this in Application_Start of global.asax. When I run in VisualStudio (by pressing F5) it works fine and my dtos are into the view, So when I publish this in IIS, I get a security exception =( in first line of conversion: Mapper.CreateMap(); <--- this line throw exception Mapper.CreateMap(); System.Security.SecurityException: Failed request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

  • FTP server output and accents

There should be an "é" (e with acute accent) instead of the double character "é". This reminds me of an issue encountered previously with JSF where there was a mix-up between standards. I have little experience with character-encoding though so I'm not sure what's happening. I'm supposing that the server output is in ASCII so how do I adapt the output so it appears correctly in the console?

  • Asp.Net MVC Tutorial Unit Tests

    - by Nicholas
    I am working through Steve Sanderson's book Pro ASP.NET MVC Framework and I having some issues with two unit tests which produce errors. In the example below it tests the CheckOut ViewResult: [AcceptVerbs(HttpVerbs.Post)] public ViewResult CheckOut(Cart cart, FormCollection form) { // Empty carts can't be checked out if (cart.Lines.Count == 0) { ModelState.AddModelError("Cart", "Sorry, your cart is empty!"); return View(); } // Invoke model binding manually if (TryUpdateModel(cart.ShippingDetails, form.ToValueProvider())) { orderSubmitter.SubmitOrder(cart); cart.Clear(); return View("Completed"); } else // Something was invalid return View(); } with the following unit test [Test] public void Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error() { // Arrange CartController controller = new CartController(null, null); Cart cart = new Cart(); cart.AddItem(new Product(), 1); // Act var result = controller.CheckOut(cart, new FormCollection { { "Name", "" } }); // Assert Assert.IsEmpty(result.ViewName); Assert.IsFalse(result.ViewData.ModelState.IsValid); } I have resolved any issues surrounding 'TryUpdateModel' by upgrading to ASP.NET MVC 2 (Release Candidate 2) and the website runs as expected. The associated error messages are: *Tests.CartControllerTests.Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error: System.ArgumentNullException : Value cannot be null. Parameter name: controllerContext* and the more detailed at System.Web.Mvc.ModelValidator..ctor(ModelMetadata metadata, ControllerContext controllerContext) at System.Web.Mvc.DefaultModelBinder.OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) at System.Web.Mvc.DefaultModelBinder.BindComplexModel(ControllerContext controllerContext, ModelBindingContext bindingContext) at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, String prefix, String[] includeProperties, String[] excludeProperties, IValueProvider valueProvider) at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, IValueProvider valueProvider) at WebUI.Controllers.CartController.CheckOut(Cart cart, FormCollection form) Has anyone run into a similar issue or indeed got the test to pass?

  • What is the proper query to get all the children in a tree?

    - by Nathan Adams
    Lets say I have the following MySQL structure: CREATE TABLE `domains` ( `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, `domain` CHAR(50) NOT NULL, `parent` INT(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=MYISAM AUTO_INCREMENT=10 DEFAULT CHARSET=latin1 insert into `domains`(`id`,`domain`,`parent`) values (1,'.com',0); insert into `domains`(`id`,`domain`,`parent`) values (2,'example.com',1); insert into `domains`(`id`,`domain`,`parent`) values (3,'sub1.example.com',2); insert into `domains`(`id`,`domain`,`parent`) values (4,'sub2.example.com',2); insert into `domains`(`id`,`domain`,`parent`) values (5,'s1.sub1.example.com',3); insert into `domains`(`id`,`domain`,`parent`) values (6,'s2.sub1.example.com',3); insert into `domains`(`id`,`domain`,`parent`) values (7,'sx1.s1.sub1.example.com',5); insert into `domains`(`id`,`domain`,`parent`) values (8,'sx2.s2.sub1.example.com',6); insert into `domains`(`id`,`domain`,`parent`) values (9,'x.sub2.example.com',4); In my mind that is enough to emulate a simple tree structure: .com | example / \ sub1 sub2 ect My problem is that give sub1.example.com I want to know all the children of sub1.example.com without using multiple queries in my code. I have tried joining the table to itself and tried to use subqueries, I can't think of anything that will reveal all the children. At work we are using MPTT to keep in hierarchal order a list of domains/subdomains however, I feel that there is an easier way to do it. I did some digging and someone did something similar but they required the use of a function in MySQL. I don't think for something simple like this we would need a whole function. Maybe I am just dumb and not seeing some sort of obvious solution. Also, feel free to alter the structure.

  • MySQL Connector for .NET - Is it REALLY mature?

    - by effkay
    After spending a miserable month with MySQL/.NET/EntityFramework, my findings: Support for Entity Framework is VERY primitive, please use it for student-subjects type of database. Kindly do not consider it using for serious development as they ARE STILL unable to sort out VERY BASIC things like: it DOES NOT support unsigned stuff it DOES NOT support unsigned columns as FK; if you try, it gives you a beautiful exception; "The specified value is not an instance of a valid constant type\r\nParameter name: value" [http://bugs.mysql.com/bug.php?id=44801] blob cannot store more then few KB; cannot compare null object with a column with a LEGAL null value [http://bugs.mysql.com/bug.php?id=49936] they are unable to write VERY PRIMITIVE check to return date as null if value in column is 0000-00-00 00:00:00 if you use Visual Studio; sorry; mysql/sun guys hate Microsoft, they will NOT LET you import more then two or three tables (for Micky Mouse type of tables, they allow five; but thats it) - if you try, it will throw TIME OUT error on your face ... unless you are smart enough to change the connection time in connection string Anyone who would like to add in above list? WISH I would have seen a list like this before I selected MySQL :(

  • JAX-WS errors when SOAP body contains UTF-8 BOM

    - by Vinny Carpenter
    I have developed a Web Service using JAX-WS (v2.1.3 - Sun JDK 1.6.0_05) deployed on WebLogic 10.3 that works just fine when I use a Java client or SoapUI or other Web Services testing tools. I need to consume this service using 2005 Microsoft SQL Server Reporting Services and I get the following error Couldn't create SOAP message due to exception: XML reader error: unexpected character content SEVERE: Couldn't create SOAP message due to exception: XML reader error: unexpected character content: "?" com.sun.xml.ws.protocol.soap.MessageCreationException: Couldn't create SOAP message due to exception: XML reader error: unexpected character content: "?" at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:292) at com.sun.xml.ws.transport.http.HttpAdapter.decodePacket(HttpAdapter.java:276) at com.sun.xml.ws.transport.http.HttpAdapter.access$500(HttpAdapter.java:93) at com.sun.xml.ws.transport.http.HttpAdapter$HttpToolkit.handle(HttpAdapter.java:432) at com.sun.xml.ws.transport.http.HttpAdapter.handle(HttpAdapter.java:244) at com.sun.xml.ws.transport.http.servlet.ServletAdapter.handle(ServletAdapter.java:134) at com.sun.xml.ws.transport.http.servlet.WSServletDelegate.doGet(WSServletDelegate.java:129) at com.sun.xml.ws.transport.http.servlet.WSServletDelegate.doPost(WSServletDelegate.java:160) at com.sun.xml.ws.transport.http.servlet.WSServlet.doPost(WSServlet.java:75) at javax.servlet.http.HttpServlet.service(HttpServlet.java:727) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:227) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:292) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:175) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:3498) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(Unknown Source) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2180) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:2086) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1406) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:201) at weblogic.work.ExecuteThread.run(ExecuteThread.java:173) Caused by: com.sun.xml.ws.streaming.XMLStreamReaderException: XML reader error: unexpected character content: "?" at com.sun.xml.ws.streaming.XMLStreamReaderUtil.nextElementContent(XMLStreamReaderUtil.java:102) at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:174) at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:296) at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:128) at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:287) ... 22 more If I use a HTTP proxy to sniff out what SSRS is sending to JAX-WS, I see EF BB BF as the beginning of the post body and JAX-WS doesn't like that. If I remove the special characters and resubmit the request using Fiddler, then the web-service invocation works. Why does JAX-WS blow up with the standard UTF-8 BOM? Is there a workaround to get past this issue? Any suggestions would be greatly appreciated. Thanks --Vinny

  • .NET: IOException for permissions when creating new file?

    - by Rosarch
    I am trying to create a new file and write XML to it: FileStream output = File.Create(Path.Combine(PATH_TO_DATA_DIR, fileName)); The argument evaluates to: C:\path\to\Data\test.xml The exception is: The process cannot access the file 'C:\path\to\Data\test.xml' because it is being used by another process. What am I doing wrong here? UPDATE: This code throws the same exception: StreamWriter writer = new StreamWriter(Path.Combine(PATH_TO_DATA_DIR, fileName)); UPDATE 2: The file I am trying to create does not exist in the file system. So how can be it in use?

  • Is there a better way than this to find out if an IsolatedStorage file exists or not?

    - by Edward Tanguay
    I'm using IsolatedStorage in a Silverlight application for caching, so I need to know if the file exists or not which I do with the following method. I couldn't find a FileExists method for IsolatedStorage so I'm just catching the exception, but it seems to be a quite general exception, I'm concerned it will catch more than if the file doesn't exist. Is there a better way to find out if a file exists in IsolatedStorage than this: public static string LoadTextFromIsolatedStorageFile(string fileName) { string text = String.Empty; using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication()) { try { using (IsolatedStorageFileStream isfs = new IsolatedStorageFileStream(fileName, FileMode.Open, isf)) { using (StreamReader sr = new StreamReader(isfs)) { string lineOfData = String.Empty; while ((lineOfData = sr.ReadLine()) != null) text += lineOfData; } } return text; } catch (IsolatedStorageException ex) { return ""; } } }
