  • Getting DirectoryNotFoundException when trying to Connect to Device with CoreCon API

    - by ageektrapped
    I'm trying to use the CoreCon API in Visual Studio 2008 to programmatically launch device emulators. When I call device.Connect(), I inexplicably get a DirectoryNotFoundException. I get it if I try it in PowerShell or in C# Console Application. Here's the code I'm using: static void Main(string[] args) { DatastoreManager dm = new DatastoreManager(1033); Collection<Platform> platforms = dm.GetPlatforms(); foreach (var p in platforms) { Console.WriteLine("{0} {1}", p.Name, p.Id); } Platform platform = platforms[3]; Console.WriteLine("Selected {0}", platform.Name); Device device = platform.GetDevices()[0]; device.Connect(); Console.WriteLine("Device Connected"); SystemInfo info = device.GetSystemInfo(); Console.WriteLine("System OS Version:{0}.{1}.{2}", info.OSMajor, info.OSMinor, info.OSBuildNo); Console.ReadLine(); } My question: Does anyone know why I'm getting this error? I'm running this on WinXP 32-bit, plain jane Visual Studio 2008 Pro. I imagine it's some config issue since I can't do it from a Console app or PowerShell. Here's the stack trace as requested: System.IO.DirectoryNotFoundException was unhandled Message="The system cannot find the path specified.\r\n" Source="Device Connection Manager" StackTrace: at Microsoft.VisualStudio.DeviceConnectivity.Interop.ConManServerClass.ConnectDevice() at Microsoft.SmartDevice.Connectivity.Device.Connect() at ConsoleApplication1.Program.Main(String[] args) in C:\Documents and Settings\Thomas\Local Settings\Application Data\Temporary Projects\ConsoleApplication1\Program.cs:line 23 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException:

  • Servlet stops without giving any exception

    - by Fahim
    Hi, I have implemented a Servlet hosted on Tomcat 6 server on Mandriva Linux. I have been able to make the client communicate with the Servlet. In response to a request the Servlet tries to instantiate a another class (named KalmanFilter) located in the same directory. The KalmanFilter tries to create four Matrices (using Jama Matrix package). But at this point Servlet stops without giving any exception ! However, from another test code in the same directory I have been able to create instance of KalmanFilter class, and proceed without any error. The problem occurs only when my Servlet tries to instantiate the KalmanFilter class and create the matrices. Any idea? Below are the codes: MyServlet.java import javax.servlet.*; import javax.servlet.http.*; import java.io.*; import java.util.*; public class MyServlet extends HttpServlet { public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{ doGet(request, response); } public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException{ PrintWriter out = null; //response.getWriter(); try{ System.out.println("creating new KalmanFilter"); KalmanFilter filter = new KalmanFilter(); out = response.getWriter(); out.print("filter created"); }catch(Exception ex){ ex.printStackTrace(); System.out.println("Exception in doGet(): " + ex.getMessage()); ex.printStackTrace(out); } } } KalmanFilter.java import Jama.Matrix; public class KalmanFilter { protected Matrix X, X0; protected Matrix F, Q; //protected Matrix F, B, U, Q; protected Matrix H, R; protected Matrix P, P0; private final double EPSILON = 0.001; public KalmanFilter(){ System.out.println("from constructor of KalmanFilter"); createInitialMatrices(); } private void createInitialMatrices(){ System.out.println("from KalmanFilter.createInitialMatrices()"); double[][] pVals = { {1.0, 0.0}, {0.0, 1.0} }; double[][] qVals = { {EPSILON, EPSILON}, {EPSILON, EPSILON} }; double[][] hVals = { {1.0, 0.0}, {0.0, 1.0}, {1.0, 0.0}, {0.0, 1.0} }; double[][] xVals = { {0.0}, {0.0}, }; System.out.println("creating P Q H X matrices in createInitialMatrices()"); try{ this.P = new Matrix(pVals); System.out.println("created P matrix in createInitialMatrices()"); this.Q = new Matrix(qVals); System.out.println("created Q matrix in createInitialMatrices()"); this.H = new Matrix(hVals); System.out.println("created H matrix in createInitialMatrices()"); this.X = new Matrix(xVals); System.out.println("created X matrix in createInitialMatrices()"); System.out.println("created P Q H X matrices in createInitialMatrices()"); }catch(Exception e){ System.out.println("Exception from createInitialMatrices()"+ e.getMessage()); e.printStackTrace(); } System.out.println("returning from createInitialMatrices()"); } }

  • Java's Scanner class: using left- and right buttons with Bash

    - by Bart K.
    I'm not too familiar with Linux/Bash, so I can't really find the right terms to search for. Take the snippet: public class Main { public static void main(String[] args) { java.util.Scanner keyboard = new java.util.Scanner(System.in); while(true) { System.out.print("$ "); String in = keyboard.nextLine(); if(in.equals("q")) break; System.out.println(" "+in); } } } If I run it on my Linux box using Bash, I can't use any of the arrow buttons (I'm only interested in the left- and right button, btw). For example, if I type "test" and then try to go back by pressing the left button, ^[[D appears instead of my cursor going back one place: $ test^[[D I've tried the newer Console class as well, but the end result is the same. On Windows' cmd.exe shell, I don't have this problem. So, the question is: is there a way to change my Java code so that I can use the arrow keys without Bash transforming them in sequences like ^[[D but actually move the cursor instead? I'm hoping that I can solve this on a "programming level". If this is not possible, then I guess I'd better try my luck on Superuser to see if there's something I need to change on my Bash console. Thanks in advance.

  • Calculate car filled up times

    - by Ivan
    Here is the question: The driving distance between Perth and Adelaide is 1996 miles. On the average, the fuel consumption of a 2.0 litre 4 cylinder car is 8 litres per 100 kilometres. The fuel tank capacity of such a car is 60 litres. Design and implement a JAVA program that prompts for the fuel consumption and fuel tank capacity of the aforementioned car. The program then displays the minimum number of times the car’s fuel tank has to be filled up to drive from Perth to Adelaide. Note that 62 miles is equal to 100 kilometres. What data will you use to test that your algorithm works correctly? Here is what I've done so far: import java.util.Scanner;// public class Ex4{ public static void main( String args[] ){ Scanner input = new Scanner( System.in ); double distance, consumption, capacity, time; distance = Math.sqrt(1996/62*100); consumption = Math.sqrt(8/100); capacity = 60; time = Math.sqrt(distance*consumption/capacity); System.out.println("The car's fuel tank need to be filled up:" + time + "times"); } } I can compile it but the problem is that the result is always 0.0, can anyone help me what's wrong with it ?

  • Need help in resolving a compiler error: error: invalid conversion from ‘int’ to ‘GIOCondition’

    - by michael
    I have a simple cpp file which uses GIO. I have stripped out everything to show my compile error: Here is the error I get: My.cpp:16: error: invalid conversion from ‘int’ to ‘GIOCondition’ make[2]: *** [My.o] Error 1 Here is the complete file: #include <glib.h> static gboolean read_socket (GIOChannel *gio, GIOCondition condition, gpointer data) { return false; } void createGIOChannel() { GIOChannel* gioChannel = g_io_channel_unix_new(0); // the following is the line causing the error: g_io_add_watch(gioChannel, G_IO_IN|G_IO_HUP, read_socket, NULL); } I have seen other example using gio, and I am doing the same thing in term of calling G_IO_IN|G_IO_HUP. And the documentation http://www.gtk.org/api/2.6/glib/glib-IO-Channels.html, said I only need to include , which I did. Can you please tell me how to resolve my error? One thing I can think of is I am doing this in a cpp file. But g_io_add_watch is a c function? Thank you for any help. I have spent hours on this but did not get anywhere.

  • Why do i get exc bad access in cases when object is not nil?

    - by DixieFlatline
    I have an app that receives remote notifications. My view controller that is shown after push has a tableview. App crashes very randomly (1 in 20 tries) at line setting frame: if (!myTableView) { NSLog(@"self.myTableView is nil"); } myTableView.frame=CGRectMake(0, 70, 320, 376); This only happens when i open the app, then open some other apps and then receive the push notification. I guess it has something to do with memory. I use ARC (ios 5). The strange thing is that nslog is not displayed, so tableview is not nil. Crash log: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x522d580c Crashed Thread: 0 Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libobjc.A.dylib 0x352b1f7e objc_msgSend + 22 1 Foundation 0x37dc174c NSKVOPendingNotificationCreate + 216 2 Foundation 0x37dc1652 NSKeyValuePushPendingNotificationPerThread + 62 3 Foundation 0x37db3744 NSKeyValueWillChange + 408 4 Foundation 0x37d8a848 -[NSObject(NSKeyValueObserverNotification) willChangeValueForKey:] + 176 5 Foundation 0x37e0ca14 _NSSetPointValueAndNotify + 76 6 UIKit 0x312af25a -[UIScrollView(Static) _adjustContentOffsetIfNecessary] + 1890 7 UIKit 0x312cca54 -[UIScrollView setFrame:] + 548 8 UIKit 0x312cc802 -[UITableView setFrame:] + 182 9 POViO 0x000913cc -[FeedVC viewWillAppear:] (FeedVC.m:303) Dealloc is not called because it is not logged: - (void)dealloc { NSLog(@"dealloc"); }

  • Asp.net Crawler Webresponse Operation Timed out.

    - by Leon
    Hi I have built a simple threadpool based web crawler within my web application. Its job is to crawl its own application space and build a Lucene index of every valid web page and their meta content. Here's the problem. When I run the crawler from a debug server instance of Visual Studio Express, and provide the starting instance as the IIS url, it works fine. However, when I do not provide the IIS instance and it takes its own url to start the crawl process(ie. crawling its own domain space), I get hit by operation timed out exception on the Webresponse statement. Could someone please guide me into what I should or should not be doing here? Here is my code for fetching the page. It is executed in the multithreaded environment. private static string GetWebText(string url) { string htmlText = ""; HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url); request.UserAgent = "My Crawler"; using (WebResponse response = request.GetResponse()) { using (Stream stream = response.GetResponseStream()) { using (StreamReader reader = new StreamReader(stream)) { htmlText = reader.ReadToEnd(); } } } return htmlText; } And the following is my stacktrace: at System.Net.HttpWebRequest.GetResponse() at CSharpCrawler.Crawler.GetWebText(String url) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 366 at CSharpCrawler.Crawler.CrawlPage(String url, List1 threadCityList) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 105 at CSharpCrawler.Crawler.CrawlSiteBuildIndex(String hostUrl, String urlToBeginSearchFrom, List1 threadCityList) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 89 at crawler_Default.threadedCrawlSiteBuildIndex(Object threadedCrawlerObj) in c:\myAppDev\myApp\site\crawler\Default.aspx.cs:line 108 at System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object state) at System.Threading.ExecutionContext.runTryCode(Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem() at System.Threading.ThreadPoolWorkQueue.Dispatch() at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback() Thanks and cheers, Leon.

  • Java UTF-8 to ASCII conversion with supplements

    - by bozo
    Hi, we are accepting all sorts of national characters in UTF-8 string on the input, and we need to convert them to ASCII string on the output for some legacy use. (we don't accept Chinese and Japanese chars, only European languages) We have a small utility to get rid of all the diacritics: public static final String toBaseCharacters(final String sText) { if (sText == null || sText.length() == 0) return sText; final char[] chars = sText.toCharArray(); final int iSize = chars.length; final StringBuilder sb = new StringBuilder(iSize); for (int i = 0; i < iSize; i++) { String sLetter = new String(new char[] { chars[i] }); sLetter = Normalizer.normalize(sLetter, Normalizer.Form.NFC); try { byte[] bLetter = sLetter.getBytes("UTF-8"); sb.append((char) bLetter[0]); } catch (UnsupportedEncodingException e) { } } return sb.toString(); } The question is how to replace all the german sharp s (ß, Ð, d) and other characters that get through the above normalization method, with their supplements (in case of ß, supplement would probably be "ss" and in case od Ð supplement would be either "D" or "Dj"). Is there some simple way to do it, without million of .replaceAll() calls? So for example: Ðonardan = Djonardan, Blaß = Blass and so on. We can replace all "problematic" chars with empty space, but would like to avoid this to make the output as similar to the input as possible. Thank you for your answers, Bozo

  • How to Manage project in this scenario

    - by vijay.shad
    Hi All, I am working on a web application which has got good amount of static or pre-login pages. These pages can have some simple forms as well where we would like to capture the visitor's details. Post login, I have got my main application. I am confused about the development and deployment architecture of my application. Post login part of my application has a release cycle of 1-2 months while pre-login pages are to be updated on a weekly basis. It is difficult to make a release of pre-login pages as the overall war also contains post-login application & which sometimes is not release ready. Currently, I have got both these parts bundled in the single war project. Please help me by letting me know the best practices whereby I can achieve following: Manage the releases of these two parts independently. I am using Maven. So is there a way I can share the resources, such as CSS, images etc between these two parts. Header and footer of my application is going to be same on pre-login & post-login pages. I was thinking of deploying these apps as two war files in my tomcat container. But then how will I manage the common resources like Css, images etc. Rgds Vijay

  • pass Validation error to UI element in WPF?

    - by Tony
    I am using IDataErrorInfo to validate my data in a form in WPF. I have the validation implemented in my presenter. The actual validation is happening, but the XAML that's supposed to update the UI and set the style isn't happening. Here it is: <Style x:Key="textBoxInError" TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/> <Setter Property="Background" Value="Red"/> </Trigger> </Style.Triggers> </Style> The problem is that my binding to Validation.Errors contains no data. How do I get this data from the Presenter class and pass it to this XAML so as to update the UI elements? EDIT: Textbox: <TextBox Style="{StaticResource textBoxInError}" Name="txtAge" Height="23" Grid.Row="3" Grid.Column="0" HorizontalAlignment="Right" VerticalAlignment="Center" Width="150"> <TextBox.Text> <Binding Path="StrAge" Mode="TwoWay" ValidatesOnDataErrors="True" UpdateSourceTrigger="PropertyChanged"/> </TextBox.Text> The validation occurs, but the style to be applied when data is invalid is not happening.

  • iPhone UITableView stutters with custom cells. How can I get it to scroll smoothly?

    - by Charles S.
    I'm using a UITableView to display custom cells created with Interface Builder. The table scrolling isn't very smooth (it "stutters") which leaves me to believe cells aren't being reused. Is there something wrong with this code? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"TwitterCell"; TwitterCell *cell = (TwitterCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ //new cell NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"TwitterCell" owner:nil options:nil]; for(id currentObject in topLevelObjects) { if([currentObject isKindOfClass:[TwitterCell class]]) { cell = (TwitterCell *)currentObject; break; } } } if([self.tweets count] > 0) { cell.lblUser.text = [[self.tweets objectAtIndex:[indexPath row]] username]; cell.lblTime.text = [[self.tweets objectAtIndex:[indexPath row]] time]; [cell.txtText setText:[[self.tweets objectAtIndex:[indexPath row]] text]]; [[cell imgImage] setImage:[[self.tweets objectAtIndex:[indexPath row]] image]]; } else { cell.txtText.text = @"Loading..."; } cell.selectionStyle = UITableViewCellSelectionStyleNone; return cell; }

  • Populating cell in UITableView with unique items

    - by aahrens
    I have an array of URL Links that I'm trying to load into a Grouped UITableView. The goal being that I have numberOfSectionsInTableView return [url count] so I can have number of sections equal to the number of url links. Then in numberOfRowsInSection returns 1 so I only populate 1 URL for each section. The trouble I'm having is to ensure that cellForRowAtIndexPath won't keep grabbing the first url link. I suspect it's because it's always grabbing the first url because the rowIndex is always zero. Any ideas how to ensure that each cell in my UITableView is populated with a different url link? - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return [newsItems count]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease]; cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease]; cell.textLabel.lineBreakMode = UILineBreakModeWordWrap; cell.textLabel.numberOfLines = 5; } // Configure the cell. Get the title of the news item that was parsed out int newsItemIndex = [indexPath indexAtPosition: [indexPath length] - 1]; [cell.textLabel setText:[[newsItems objectAtIndex: newsItemIndex] objectForKey: @"link"]]; return cell; }

  • JTree events seem misordered

    - by MeBigFatGuy
    It appears to me that tree selection events should happen after focus events, but this doesn't seem to be the case. Assume you have a JTree and a JTextField, where the JTextField is populated by what is selected in the tree. When the user changes the text field, on focus lost, you update the tree from the text field. however, the tree selection is changed before the focus is lost on the text field. this is incorrect, right? Any ideas? Here is some sample code: import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class Focus extends JFrame { public static void main(String[] args) { Focus f = new Focus(); f.setLocationRelativeTo(null); f.setVisible(true); } public Focus() { Container cp = getContentPane(); cp.setLayout(new BorderLayout()); final JTextArea ta = new JTextArea(5, 10); cp.add(new JScrollPane(ta), BorderLayout.SOUTH); JSplitPane sp = new JSplitPane(); cp.add(sp, BorderLayout.CENTER); JTree t = new JTree(); t.addTreeSelectionListener(new TreeSelectionListener() { public void valueChanged(TreeSelectionEvent tse) { ta.append("Tree Selection changed\n"); } }); t.addFocusListener(new FocusListener() { public void focusGained(FocusEvent fe) { ta.append("Tree focus gained\n"); } public void focusLost(FocusEvent fe) { ta.append("Tree focus lost\n"); } }); sp.setLeftComponent(new JScrollPane(t)); JTextField f = new JTextField(10); sp.setRightComponent(f); pack(); f.addFocusListener(new FocusListener() { public void focusGained(FocusEvent fe) { ta.append("Text field focus gained\n"); } public void focusLost(FocusEvent fe) { ta.append("Text field focus lost\n"); } }); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }

  • How to disable auto-generated WCF configuration

    - by user351025
    Every time my program runs vs adds the default configuration to my app.config file. At that run it works fine, but at the next run it actually tries to read the config. The problem is that the default configuration has errors, it adds the attribute "Address", but attritbutes are not allowed to have capitals so it throws an exception. This means I have to remove the bad section every run! I've tried to configure the .config but it gives errors. Here is the code that I use to host the server: private static System.Threading.AutoResetEvent stopFlag = new System.Threading.AutoResetEvent(false); ServiceHost host = new ServiceHost(typeof(Service), new Uri("http://localhost:8000")); host.AddServiceEndpoint(typeof(IService), new BasicHttpBinding(), "ChessServer"); host.Open(); stopFlag.WaitOne(); host.Close(); Here is the client code that calls the server: ChannelFactory<IChessServer> scf; scf = new ChannelFactory<IService> (new BasicHttpBinding(), "http://localhost:8000"); IService service = scf.CreateChannel(); Thanks for any help.

  • Converting a Linq expression tree that relies on SqlMethods.Like() for use with the Entity Framework

    - by JohnnyO
    I recently switched from using Linq to Sql to the Entity Framework. One of the things that I've been really struggling with is getting a general purpose IQueryable extension method that was built for Linq to Sql to work with the Entity Framework. This extension method has a dependency on the Like() method of SqlMethods, which is Linq to Sql specific. What I really like about this extension method is that it allows me to dynamically construct a Sql Like statement on any object at runtime, by simply passing in a property name (as string) and a query clause (also as string). Such an extension method is very convenient for using grids like flexigrid or jqgrid. Here is the Linq to Sql version (taken from this tutorial: http://www.codeproject.com/KB/aspnet/MVCFlexigrid.aspx): public static IQueryable<T> Like<T>(this IQueryable<T> source, string propertyName, string keyword) { var type = typeof(T); var property = type.GetProperty(propertyName); var parameter = Expression.Parameter(type, "p"); var propertyAccess = Expression.MakeMemberAccess(parameter, property); var constant = Expression.Constant("%" + keyword + "%"); var like = typeof(SqlMethods).GetMethod("Like", new Type[] { typeof(string), typeof(string) }); MethodCallExpression methodExp = Expression.Call(null, like, propertyAccess, constant); Expression<Func<T, bool>> lambda = Expression.Lambda<Func<T, bool>>(methodExp, parameter); return source.Where(lambda); } With this extension method, I can simply do the following: someList.Like("FirstName", "mike"); or anotherList.Like("ProductName", "widget"); Is there an equivalent way to do this with Entity Framework? Thanks in advance.

  • Problem with ASP.NET Authentication

    - by Niels Bosma
    I'm having problem with our login procedure. Some customers complain that they can't login. I can see in our logs that their login is successful and that they are redirected from the login page to the member area. But there somehow the login isn't detected and they are bounced back to the login page. I've asked customers to check if cookies are supported (http://www.html-kit.com/tools/cookietester/) but problem remains even if this test returns true. This is how I've implemented the login procedure (simplyfied): protected void Login(string email, string password) { FormsAuthentication.SignOut(); Guid clientId = /* Validate login by checking email and password, if fails display error otherwise get client id */ FormsAuthentication.SetAuthCookie(clientId.ToString(), true); HttpContext.Current.Response.Redirect("~/Members.aspx"); } On the member page I check for authentication by in Page_Load function: public static void IsAuthenticated() { if (!HttpContext.Current.User.Identity.IsAuthenticated) { HttpContext.Current.Response.Redirect("~/Login.aspx", true); } } Maybe I'm using FormsAuthentication completely wrong? I've asked this before but still haven't been able to figure this out, I'd appreciate any help.

  • Serialize XML child and keep namespaces in Java

    - by Guido García
    I have an Document object that is modeling a XML like this one: <RootNode xmlns="http://a.com/a" xmlns:b="http://b.com/b"> <Child /> </RootNode> Using Java DOM, I need to get the <Child> node and serialize it to XML, but keeping the root node namespaces. This is what I currently have, but it does not serialize the namespaces: public static void main(String[] args) throws Exception { String xml = "<RootNode xmlns='http://a.com/a' xmlns:b='http://b.com/b'><Child /></RootNode>"; DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder(); Document doc = builder.parse(new ByteArrayInputStream(xml.getBytes())); Node childNode = doc.getFirstChild().getFirstChild(); // serialize to string StringWriter sw = new StringWriter(); DOMSource domSource = new DOMSource(childNode); StreamResult streamResult = new StreamResult(sw); TransformerFactory tf = TransformerFactory.newInstance(); Transformer serializer = tf.newTransformer(); serializer.transform(domSource, streamResult); String serializedXML = sw.toString(); System.out.println(serializedXML); } Current output: <?xml version="1.0" encoding="UTF-8"?> <Child/> Expected output: <?xml version="1.0" encoding="UTF-8"?> <Child xmlns='http://a.com/a' xmlns:b='http://b.com/b' />

  • Flex through Flash Builder 4; Connecting to a dynamic XML feed: "The response is not a valid XML or

    - by jtromans
    I am learning how to use Flex with Adobe Flash Builder 4 standalone. I am working my through the Adobe Flash Build 4 Bible by David Gassner. This has led me to create my own micro problems to try and solve. I am trying to connect to a dynamix XML feed created by the following aspx page: generate_xml.aspx When I create the data connection through the Data/Service panel, I can pick between XML and HTTP. I figured because the generate_xml.aspx has to generate the XML file first, I should use the HTTP service as opposed to the XML. The HTTP service offers GET, which seems to be the kinda thing I want. However, I am really struggling to do this. I keep getting: "The response is not a valid XML or a JSON string" The actual STATIC generated XML file that is created by this page works perfectly when I save it and manually connect with the XML service. Therefore I know my XML code is properly formatted and contains no other HTML of JavaScript. I figure my problem occurs because the page itself is .aspx, but I cannot work out how to successfully ask Flex to request the output of this page, rather than the page itself.

  • Why ClassCastException on JMS ConnectionFactory lookup in JNDI?

    - by Derek Mahar
    What might be the cause of the following ClassCastException in a standalone JMS client application when it attempts to retrieve a connection factory from the JNDI provider? Exception in thread "main" java.lang.ClassCastException: javax.naming.Reference cannot be cast to javax.jms.ConnectionFactory Here is an abbreviated version of the JMS client that includes only its start() and stop() methods. The exception occurs on the first line in method start() which attempts to retrieve the connection factory from the JNDI provider, a remote LDAP server. The JMS connection factory and destination objects are on a remote JMS server. class JmsClient { private ConnectionFactory connectionFactory; private Connection connection; private Session session; private MessageConsumer consumer; private Topic topic; public void stop() throws JMSException { consumer.close(); session.close(); connection.close(); } public void start(Context context, String connectionFactoryName, String topicName) throws NamingException, JMSException { // ClassCastException occurs when retrieving connection factory. connectionFactory = (ConnectionFactory) context.lookup(connectionFactoryName); connection = connectionFactory.createConnection("username","password"); session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); topic = (Topic) context.lookup(topicName); consumer = session.createConsumer(topic); connection.start(); } private static Context getInitialContext() throws NamingException, IOException { String filename = "context.properties"; Properties props = new Properties(); props.load(new FileInputStream(filename)); return new InitialContext(props); } }

  • Trouble with C# array

    - by Biosci3c
    Hi, I am writing a card playing program as a way of learning C#. I ran into an issue with an array going out of bounds. Here is my code: namespace Pcardconsole { class Deck { public Deck() { // Assign standard deck to new deck object int j; for (int i = 0; i != CurrentDeck.Length; i++) { CurrentDeck[i] = originalCards[i]; } // Fisher-Yates Shuffling Algorithim Random rnd = new Random(); for (int k = CurrentDeck.Length - 1; k >= 0; k++) { int r = rnd.Next(0, k + 1); int tmp = CurrentDeck[k]; CurrentDeck[k] = CurrentDeck[r]; CurrentDeck[r] = tmp; // Console.WriteLine(i); } } public void Shuffle() { // TODO } // public int[] ReturnCards() // { // TODO // } public int[] originalCards = new int[54] { 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1A, 0x1B, 0x1C, 0x1D, 0x21, 0x22, 0x23, 0x24, 0x25, 0x26, 0x27, 0x28, 0x29, 0x2A, 0x2B, 0x2C, 0x2D, 0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, 0x3A, 0x3B, 0x3C, 0x3D, 0x41, 0x42, 0x43, 0x44, 0x45, 0x46, 0x47, 0x48, 0x49, 0x4A, 0x4B, 0x4C, 0x4D, 0x50, 0x51 }; public int[] CurrentDeck = new int[54]; } class Program { static void Main(string[] args) { // Create a Deck object Deck mainDeck = new Deck(); Console.WriteLine("Here is the card array:"); for (int index = 0; index != mainDeck.CurrentDeck.Length; index++) { string card = mainDeck.CurrentDeck[index].ToString("x"); Console.WriteLine("0x" + card); } } } The hexidecimal numbers stand for different cards. When I compile it I get an array index out of bounds error, and a crash. I don't understand what is wrong. Any help would be much appreciated.
