  • CSS rules not getting applied in JSPs ?

    - by lakshmanan
    Im building a web application using struts2. I have an authentication interceptor at the top of all the interceptors (I have set it up as such) which checks whether a user is logged in. If not, it will give a login page as result. In login page, I have some set of standard CSS rules which I use for all the JSPs in the app. But that login page coming via that interceptor is not getting applied with CSS rules. Don't know why. Here is my JSP login page. <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <link rel="stylesheet" href="styles/styles.css" type="text/css" /> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Projit Login </title> </head> <body> <div id="header"> <h1>Projit</h1> </div> <div id="col1"> <s:form action="/login.action"> <s:textfield name="some field" label="Enter somefield" /> <s:textfield name="username" label="Username" /> <s:password name="password" label="Password" /> <s:submit value="Sign In" /> </s:form> </div> <div id="col2"> <h3>Login</h3> </div> <div id="footer"> some footer </div> </body> </html> the css file is present in WebContent/styles/styles.css I am using eclipse for development. this problem of CSS rules not getting applied occurs at times for other jsps as well inspite of the CSS file being present in the correct location. I guess there must be some URL thing behind this problem. I have tried hard but it is not working till now. Please help.

  • Can't make my WCF extension work

    - by Sergio Romero
    I have a WCF solution that consists of the following class libraries: Exercise.Services: Contains the implementation classes for the services. Exercise.ServiceProxy: Contains the classes that are instantiated in the client. Exercise.HttpHost: Contains the services (*.svc files). I'm calling the service from a console application and the "first version" works really well so I took the next step which is to create a custom ServiceHostFactory, ServiceHost, and InstanceProvider so I can use constructor injection in my services as it is explained in this article. These classes are implemented in yet another class library: 4. Exercise.StructureMapWcfExtension Now even though I've modified my service this: <%@ ServiceHost Language="C#" Debug="true" Factory="Exercise.StructureMapWcfExtension.StructureMapServiceHostFactory" Service="Exercise.Services.PurchaseOrderService" %> I always get the following exception: System.ServiceModel.CommunicationException Security negotiation failed because the remote party did not send back a reply in a timely manner. This may be because the underlying transport connection was aborted. It fails in this line of code: public class PurchaseOrderProxy : ClientBase<IPurchaseOrderService>, IPurchaseOrderService { public PurchaseOrderResponse CreatePurchaseOrder(PurchaseOrderRequest purchaseOrderRequest) { return base.Channel.CreatePurchaseOrder(purchaseOrderRequest); //Fails here } } But that is not all, I added a trace to the web.config file and this is the error that appears in the log file: System.InvalidOperationException The service type provided could not be loaded as a service because it does not have a default (parameter-less) constructor. To fix the problem, add a default constructor to the type, or pass an instance of the type to the host. So this means that my ServiceHostFactory is never being hit, I even set a breakpoint in both its constructor and its method and they never get hit. I've added a reference of the StructureMapWcfExtension library to all the other ones (even the console client), one by one to no avail. I also tried to use the option in the host's web.config file to configure the factory like so: <serviceHostingEnvironment> <serviceActivations> <add service="Exercise.Services.PurchaseOrderService" relativeAddress="PurchaseOrderService.svc" factory="Exercise.StructureMapWcfExtension.StructureMapServiceHostFactory"/> </serviceActivations> </serviceHostingEnvironment> That didn't work either. Please I need help in getting this to work so I can incorporate it to our project. Thank you. UPDATE: Here's the service host factory's code: namespace Exercise.StructureMapWcfExtension { public class StructureMapServiceHostFactory : ServiceHostFactory { private readonly Container Container; public StructureMapServiceHostFactory() { Container = new Container(); new ContainerConfigurer().Configure(Container); } protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { return new StructureMapServiceHost(Container, serviceType, baseAddresses); } } public class ContainerConfigurer { public void Configure(Container container) { container.Configure(r => r.For<IPurchaseOrderFacade>().Use<PurchaseOrderFacade>()); } } }

  • How do I access SourceGear Web services using SOAP::Lite?

    - by user565793
    For some reason SourceGear provide an undocumented Web service on their installations. They actually ask developers to use the API instead because the Web service is kinda messy, but this is a problem in my case because I cannot use this API on a Perl environment, so their solution for my specific case is to use the Web service. This shouldn't be a problem. Using SOAP::Lite I have connected to several Web services in the past in the same way. But the lack of documentation is a major chaos if you don't know where the SOAP calls can be made. I only have an XML to decipher where to and how to make these calls. It would be great if a real SOAP genius could help me out in this. This is an example of the login call and the expected response: Request POST /fortress/dragnetwebservice.asmx HTTP/1.1 Host: velecloudserver Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://www.sourcegear.com/schemas/dragnet/LoginPlainText" <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <LoginPlainText xmlns="http://www.sourcegear.com/schemas/dragnet"> <strLogin>string</strLogin> <strPassword>string</strPassword> </LoginPlainText> </soap:Body> </soap:Envelope> Response HTTP/1.1 200 OK Content-Type: text/xml; charset=utf-8 Content-Length: length <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <LoginPlainTextResponse xmlns="http://www.sourcegear.com/schemas/dragnet"> <LoginPlainTextResult>int</LoginPlainTextResult> <strAuthTicket>string</strAuthTicket> </LoginPlainTextResponse> </soap:Body> </soap:Envelope> I'm looking for a way to be able to assemble this somehow. This is my Perl example: my $soap = SOAP::Lite -> uri ('http://velecloudserver/fortress/dragnetwebservice.asmx') -> proxy('http://velecloudserver/fortress/dragnetwebservice.asmx/LoginPlainText'); my $som = $soap->call('LoginPlainText', SOAP::Data->name('LoginPlainText')->value( \SOAP::Data->value([ SOAP::Data->name('strLogin')->value( 'admin' ), SOAP::Data->name('strPassword')->value('Adm1234'), ])) ); Any tip would be appreciated.

  • Bogus WPF / XAML errors in Visual Studio 2010

    - by epalm
    There are bogus errors hanging around, but at runtime everything works. Right now, I'm getting Cannot locate resource 'img/icons/silk/arrow_refresh.png'. I've got a simple UserControl called ImageButton (doesn't everyone?): <UserControl x:Class="WinDispatchClientWpf.src.controls.ImageButton" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d"> <Button Name="btnButton" Click="btnButton_Click"> <StackPanel Orientation="Horizontal"> <Image Name="btnImage" Stretch="None" /> <TextBlock Name="btnText" /> </StackPanel> </Button> </UserControl> Which does what you'd expect: [ContentProperty("Text")] public partial class ImageButton : UserControl { public String Image { set { btnImage.Source = GuiUtil.CreateBitmapImage(value); } } public String Text { set { btnText.Text = value; } } public double Gap { set { btnImage.Margin = new Thickness(0, 0, value, 0); } } public bool ToolBarStyle { set { if (value) { btnButton.Style = (Style)FindResource(ToolBar.ButtonStyleKey); } } } public bool IsCancel { set { btnButton.IsCancel = value; } } public bool IsDefault { set { btnButton.IsDefault = value; } } public event RoutedEventHandler Click; public ImageButton() { InitializeComponent(); } private void btnButton_Click(object sender, RoutedEventArgs e) { if (Click != null) { Click(sender, e); } } } Where CreateBitmapImage is the following: public static BitmapImage CreateBitmapImage(string imagePath) { BitmapImage icon = new BitmapImage(); icon.BeginInit(); icon.UriSource = new Uri(String.Format("pack://application:,,,/{0}", imagePath)); icon.EndInit(); return icon; } I can't see the design view of any xaml file that uses an ImageButton like such: <Window foo="bar" xmlns:wpfControl="clr-namespace:MyProj.src.controls"> <Grid> <wpfControl:ImageButton ToolBarStyle="True" Gap="3" Click="btnRefresh_Click" Text="Refresh" Image="img/icons/silk/arrow_refresh.png" /> </Grid> </Window> Why is VS complaining?

  • CI pagination, POST problem

    - by Gwood
    Okay, I am pretty new in CI and I am stuck on pagination. I am performing this pagination on a record set that is result of a query. Now everything seems to be working fine. But there’s some problem probably with the link. I am displaying 10 results per page. Now if the results are less than 10 then it’s fine. Or If I pull up the entire records in the table it works fine. But in case the result is more than 10 rows, then the first 10 is perfectly displayed, and when I click on the pagination link to get to the next page the next page displays the rest of the results from the query as well as, other records in the table. ??? I am confused.. Any help?? Here’s the model code I am using .... function getTeesLike($field,$param) { $this-db-like($field,$param); $this-db-limit(10, $this-uri-segment(3)); $query=$this-db-get(‘shirt’); if($query-num_rows()0){ return $query-result_array(); } } function getNumTeesfromQ($field,$param) { $this-db-like($field,$param); $query=$this-db-get(‘shirt’); return $query-num_rows(); } And here’s the controller code .... $KW=$this-input-post(‘searchstr’); $this-load-library(‘pagination’); $config[‘base_url’]=‘http://localhost/cit/index.php/tees/show/’; $config[‘total_rows’]=$this-T-getNumTeesfromQ(‘Title’,$KW); $config[‘per_page’]=‘10’; $this-pagination-initialize($config); $data[‘tees’]=$this-T-getTeesLike(‘Title’,$KW); $data[‘title’]=‘Displaying Tees data’; $data[‘header’]=‘Tees List’; $data[‘links’]=$this-pagination-create_links(); $this-load-view(‘tee_res’, $data); //What am I doing wrong here ???? Pls help ... I guess the problem is with the $KW=$this-input-post(‘searchstr’); .. Because if I hard code a value for $KW it works fine. May be I should use POST differently ..but how do I pass the value from the form without POSTING it , its CI so not GET ... ??????

  • WPF Reusing Xaml Effectively

    - by Steve
    Hi, I've recently been working on a project using WPF to produce a diagram. In this I must show text alongside symbols that illustrate information associated with the text. To draw the symbols I initially used some png images I had produced. Within my diagram these images appeared blurry and only looked worse when zoomed in on. To improve on this I decided I would use a vector rather than a rastor image format. Below is the method I used to get the rastor image from a file path: protected Image GetSymbolImage(string symbolPath, int symbolHeight) { Image symbol = new Image(); symbol.Height = symbolHeight; BitmapImage bitmapImage = new BitmapImage(); bitmapImage.BeginInit(); bitmapImage.UriSource = new Uri(symbolPath); bitmapImage.DecodePixelHeight = symbolHeight; bitmapImage.EndInit(); symbol.Source = bitmapImage; return symbol; } Unfortunately this does not recognise vector image formats. So instead I used a method like the following, where "path" is the file path to a vector image of the format .xaml: public static Canvas LoadXamlCanvas(string path) { //if a file exists at the specified path if (File.Exists(path)) { //store the text in the file string text = File.ReadAllText(path); //produce a canvas from the text StringReader stringReader = new StringReader(text); XmlReader xmlReader = XmlReader.Create(stringReader); Canvas c = (Canvas)XamlReader.Load(xmlReader); //return the canvas return c; } return null; } This worked but drastically killed performance when called repeatedly. I found the logic necessary for text to canvas conversion (see above) was the main cause of the performance problem therefore embedding the .xaml images would not alone resolve the performance issue. I tried using this method only on the initial load of my application and storing the resulting canvases in a dictionary that could later be accessed much quicker but I later realised when using the canvases within the dictionary I would have to make copies of them. All the logic I found online associated with making copies used a XamlWriter and XamlReader which would again just introduce a performance problem. The solution I used was to copy the contents of each .xaml image into its own user control and then make use of these user controls where appropriate. This means I now display vector graphics and performance is much better. However this solution to me seems pretty clumsy. I'm new to WPF and wonder if there is some built in way of storing and reusing xaml throughout an application? Apologies for the length of this question. I thought having a record of my attempts might help someone with any similar problem. Thanks.

  • WPF Binding when setting DataTemplate Programically

    - by Daniel
    Hello, I have my little designer tool (my program). On the left side I have TreeView and on the right site I have Accordion. When I select a node I want to dynamically build Accordion Items based on Properties from DataContext of selected node. Selecting nodes works fine, and when I use this sample code for testing it works also. XAML code: <layoutToolkit:Accordion x:Name="accPanel" SelectionMode="ZeroOrMore" SelectionSequence="Simultaneous"> <layoutToolkit:AccordionItem Header="Controller Info"> <StackPanel Orientation="Horizontal" DataContext="{Binding}"> <TextBlock Text="Content:" /> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </layoutToolkit:AccordionItem> </layoutToolkit:Accordion> C# code: private void treeSceneNode_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) { if (e.NewValue != e.OldValue) { if (e.NewValue is SceneNode) { accPanel.DataContext = e.NewValue; //e.NewValue is a class that contains Name property } } } But the problem occurs when I'm trying to achive this using DateTemplate and dynamically build AccordingItem, the Binding is not working: <layoutToolkit:Accordion x:Name="accPanel" SelectionMode="ZeroOrMore" SelectionSequence="Simultaneous"> </layoutToolkit:Accordion> and DateTemplate in my ResourceDictionary <DataTemplate x:Key="dtSceneNodeContent"> <StackPanel Orientation="Horizontal" DataContext="{Binding}"> <TextBlock Text="Content:" /> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </DataTemplate> and C# code: private void treeSceneNode_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) { if (e.NewValue != e.OldValue) { ResourceDictionary rd = new ResourceDictionary(); rd.Source = new Uri("/SilverGL.GUI;component/SilverGLDesignerResourceDictionary.xaml", UriKind.RelativeOrAbsolute); if (e.NewValue is SceneNode) { accPanel.DataContext = e.NewValue; AccordionItem accController = new AccordionItem(); accController.Header = "Controller Info"; accController.ContentTemplate = rd["dtSceneNodeContent"] as DataTemplate; accPanel.Items.Add(accController); } else { // Other type of node } } } I really need help with this issue. Thanks for any support. Daniel

  • How can I map a spring controller to a url with .jsp extension?

    - by Matteo Caprari
    Hi. We are in the process of migrating a jsp-only application to Spring-MVC. For various reasons we can't change the extension of the current pages. (calls to login.jsp need to handled by a spring controller that will use a jsp file as view). We are doing this iteratively, so some pages need to stay jsp files (calls to welcome.jsp won't be handled by a controller). To do that I mapped both the DispatcherDervlet and the HandlerMapping to *.jsp, and configured the JstlView in the standard way. Unfortunately, if I browse to //login.jsp I get an error saying <No mapping found for HTTP request with URI [/<context>/WEB-INF/jsp/login.jsp] in DispatcherServlet with name 'spring'> It all works if I change .jsp to any other extension in DispatcherServlet and HandlerMapping. web.xml: <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.jsp</url-pattern> </servlet-mapping> spring-servlet.xml: <!-- View resolver --> <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> <!-- URL Mapping --> <bean id="publicUrlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="urlMap"> <map> <entry key="/login.jsp" value-ref="loginController"/> </map> </property> </bean> Thanks a lot.

  • Thin & Sinatra not taking port

    - by NekoNova
    I'm having problems settig up my application using Thin and Sinatra. I have created a development-config.ru file that contains the following settings: # This is a rack configuration file to fire up the Sinatra application. # This allows better control and configuration as we are using the modular # approach here for controlling our application. # # Extend the Ruby load path with the root of the API and the lib folder # so that we can automatically include all our own custom classes. This makes # the requiring of files a bit cleaner and easier to maintain. # This is basically what rails does as well. # We also store the root of the API in the ENV settings to ensure we have # always access to the root of the API when building paths. ENV['API_ROOT'] = File.dirname(__FILE__) $:.unshift ENV['API_ROOT'] $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'lib')) $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'db')) # Now we can require all the gems used for the entire API by simpling requiring # them here. We can also include the classes that we have defined inside the lib # folder. require 'rubygems' require 'bundler' # Run Bundler to setup our gems properly. This will install all the missing gems on # the system and ensure that the deployment environment is ready to run. Bundler.require # To make the loading easier for the application, we will now automatically load all # models that have been defined inside the lib folder. This ensures that we do not need # to load them anymore anywhere else in our application, as the models will be known to # ruby everywhere. Dir.glob(File.join(ENV['API_ROOT'], 'lib', '**', '*.rb')).each{|file| require file} # Now we will configure the Sinatra application so that we can fire up the entire API. # This requires some detailed settings like whether logging is allowed, the port to be # used and some folder locations. require 'sinatra' require 'app' set :logging, true set :dump_errors, true set :port, 3001 set :views, "#{ENV['API_ROOT']}/views" set :public_folder, "#{ENV['API_ROOT']}/public" set :environment, :test # Start up the Sinatra application with all the settings that we have defined. run App.new This is based upon the information I found on the Sinatra website. However, the problem is that I cannot get the application running on port 3001. If I use thin start -R development-config.ru it runs on port 3000. If I use rackup config-development.ru it runs on port 9696. However I never see Sinatra kick in or run over port 3000. My application looks like this: # Author : Arne De Herdt # Email : # This is the actuall application that will be running under Sinatra # to serve the requests for the billing middleware API. # We use the modular approach here to allow control when deploying # the application using Capistrano. require 'sinatra/base' require 'logger' require 'savon' require 'billcrux' class App < Sinatra::Base # This action responds to POST requests on the URI '/billcrux/register' # and is responsible for handeling registration requests with the # BillCrux payment system. # The post "/billcrux/register" do # do stuff end end Can someone tell me what I am doing wrong?

  • Passing Auth to API calls with Web Service References

    - by coffeeaddict
    I am new to web services. The last time I dealt with SOAP was when I created a bunch of wrapper classes that sent requests and received responses back per some response objects/classes I had created. So I had an object to send certain API requests and likewise a set of objects to hold the response back as an object so I could utilize that 3rd party API. Then someone came to me and said why not just use the wsdl and a web service. Ok, so today I went and created a "Service Reference". I see that this is what's called a "Proxy Class". You just instantiate an instance of this and then walla you have access to all the methods from the wsdl. But this leaves me with auth questions. Back when I created my own classes manually, I had a class which exposed properties that I would set then access for things like signature, username, password that got sent along with the Http request that were required by whatever 3rd party API I was using to make API calls. But then with using a Service Reference, how then would I pass this information just like I had done in my custom classes? For instance I'm going to be working with the PayPal API. It requires you to send a signature and a few other pieces of information like username and password. // Determins if API call needs to use a session based URI string requestURI = UseAuthURI == true ? _requestURIAuthBased + aSessionID : _requestURI; byte[] data = XmlUtil.DocumentToBytes(doc); // Create the atual Request instance HttpWebRequest request = CreateWebRequest(requestURI, data.Length); So how do I pass username, password, signature, etc. when using web service references for each method call? Is it as simple as specifying it as a param to the method or do you use the .Credentials and .URL methods of your proxy class object? It seems to me Credentials means windows credentials but I could be wrong. Is it limited to that or can you use that to specify those required header values that PayPal expects with each method call/API request?

  • How to get Firefox to not continue to show "Transferring data from..." in browser status bar after a

    - by Edward Tanguay
    The following silverlight demo loads and displays a text file from a server. However, in Firefox (but not Explorer or Chrome) after you click the button and the text displays, the status bar continues to show "Transferring data from test.development..." which erroneously gives the user the belief that something is still loading. I've noticed that if you click on another Firefox tab and then back on the original one, the message goes away, so it seems to be just a Firefox bug that doesn't clear the status bar automatically. Is there a way to clear the status bar automatically in Firefox? or a way to explicitly tell it that the async loading is finished so it can clear the status bar itself?

  • Self updating app, wont overwrite existing app, using Android packagemanager?

    - by LokiSinclair
    I know there are plenty of questions about this on here, but I've tried everything (but the correct 'thing', obviously!) and nothing seems to shine any light on the problem I'm having. I've written an app (for a customer), which is designed to be hosted on their own server. The app references a simple text file with the latest version code in it and checks it against it's own version. If it's out of date it goes off and downloads the update. Everything is working as intended up to this point. I use the: Intent i = new Intent(Intent.ACTION_VIEW); i.setDataAndType(Uri.fromFile(outputFile), "application/vnd.android.package-archive"); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(i); ...code to start the install process of the newly downloaded .apk file. And that all starts as I would expect. I click on "Install" - when I'm prompted to confirm the overwriting of the current app, with the new. It starts, and then displays: App not installed. And existing package by the same name with a conflicting signature is already installed. Now I'm aware that Android can't have multiple applications sharing the same package name, which is fine, but nothing comes up in LogCat and I can only assume that the OS is annoyed at me attempting to 'update' my app, even though I'm going through all the correct channels and using the inbuilt package manager to do it for me! Can anyone tell me what the OS is moaning about? I'm not attempting to install two apps side by side, I want it to update it, which it starts to do, and then gets really confused. Is it something to do with me using the same keystore for signing the packages? I highly doubt it as I've used the same keystores previously to handle updates to games and the like, but I just can't figure out what it's complaining about. Hopefully someone out there has had this issue and solved it, and can point me in the right direction. I'm flying a bit blind with the limited information it's giving me :( Cheers.

  • Activity gets killed while executing the camera intent

    - by BlackRider
    In my app I call the system camera to take a picture, and then handle the result in onActivityResult. You know, the usual. It used to work, but now my calling activity gets killed while I'm taking the picture. Specifically, onDestroy() is called on my activity right after I press the camera shutter. The photo does get taken & saved (I've checked that the file gets written on the SD card). After I accept the photo, instead of returning to the calling activity and invoking onActivityResult, the previous activity in the activity stack gets called. I see no exceptions in the logcat. My custom exception handler doesn't get called. If it matters, my app also includes a service that listens to GPS updates, but I unregister all the receivers in onPause(). Here's the call stack for MyCallingActivity.onDestroy(): Thread [<1> main] (Suspended (breakpoint at line 303 in NewPlaceDetailsActivity)) NewPlaceDetailsActivity.onDestroy() line: 303 ActivityThread.performDestroyActivity(IBinder, boolean, int, boolean) line: 2663 ActivityThread.handleDestroyActivity(IBinder, boolean, int, boolean) line: 2694 ActivityThread.access$2100(ActivityThread, IBinder, boolean, int, boolean) line: 117 BinderProxy(ActivityThread$H).handleMessage(Message) line: 968 ActivityThread$H(Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 130 ActivityThread.main(String[]) line: 3687 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object...) line: 507 ZygoteInit$MethodAndArgsCaller.run() line: 842 ZygoteInit.main(String[]) line: 600 NativeStart.main(String[]) line: not available [native method] This is how I start the camera activity, in case you're wondering: protected void startCamera() { createPhotoDirsIfNeeded(); String fileName = "temp.jpg"; ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); m_capturedImageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); m_photoFileName = APP_PHOTO_PATH + "/" + DateFormat.format(DATE_FORMAT, Calendar.getInstance().getTime()) + ".jpg"; File picFile = new File(m_photoFileName); if(picFile.exists()) { picFile.delete(); } // start the camera activity Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(picFile)); startActivityForResult(intent, IntentHelper.REQUEST_TAKE_PHOTO); } How can I find out why does my activity get killed, AND removed from the stack instead of being created again?

  • How to download file into string with progress callback?

    - by Kaminari
    I would like to use the WebClient (or there is another better option?) but there is a problem. I understand that opening up the stream takes some time and this can not be avoided. However, reading it takes a strangely much more amount of time compared to read it entirely immediately. Is there a best way to do this? I mean two ways, to string and to file. Progress is my own delegate and it's working good. FIFTH UPDATE: Finally, I managed to do it. In the meantime I checked out some solutions what made me realize that the problem lies elsewhere. I've tested custom WebResponse and WebRequest objects, library libCURL.NET and even Sockets. The difference in time was gzip compression. Compressed stream lenght was simply half the normal stream lenght and thus download time was less than 3 seconds with the browser. I put some code if someone will want to know how i solved this: (some headers are not needed) public static string DownloadString(string URL) { WebClient client = new WebClient(); client.Headers["User-Agent"] = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5"; client.Headers["Accept"] = "application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; client.Headers["Accept-Encoding"] = "gzip,deflate,sdch"; client.Headers["Accept-Charset"] = "ISO-8859-2,utf-8;q=0.7,*;q=0.3"; Stream inputStream = client.OpenRead(new Uri(URL)); MemoryStream memoryStream = new MemoryStream(); const int size = 32 * 4096; byte[] buffer = new byte[size]; if (client.ResponseHeaders["Content-Encoding"] == "gzip") { inputStream = new GZipStream(inputStream, CompressionMode.Decompress); } int count = 0; do { count = inputStream.Read(buffer, 0, size); if (count > 0) { memoryStream.Write(buffer, 0, count); } } while (count > 0); string result = Encoding.Default.GetString(memoryStream.ToArray()); memoryStream.Close(); inputStream.Close(); return result; } I think that asyncro functions will be almost the same. But i will simply use another thread to fire this function. I dont need percise progress indication.

  • Asp.net web service: Problems accessing without www

    - by MysterM
    I have a Asp.net web service running on www.domain.com/Service.svc that I connect to using jQuery from my asp.net website. Everything works perfect if the user access my website with www.domain.com. But if the user uses only domain.com I get error: There was no channel actively listening at 'http://domain.com/Service.svc/get?date=2010-10-09'. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening. In my web.config I use the serviceHostingEnvironment tag to get the service running on my webhost (it doesn't work otherwise). Maybe this is what causes the error? Here is my system.serviceModel in web.config (I had some problems setting up the web service so that's why my web.config might be a bit messy: <system.serviceModel> <behaviors> <endpointBehaviors> <behavior name="ServiceAspNetAjaxBehavior"> <enableWebScript /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"> <baseAddressPrefixFilters> <add prefix="http://www.domain.com"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> <services> <service behaviorConfiguration="ServiceBehavior" name="Service"> <endpoint address="" behaviorConfiguration="ServiceAspNetAjaxBehavior" binding="webHttpBinding" bindingConfiguration="ServiceBinding" contract="Service" /> </service> </services> <bindings> <webHttpBinding> <binding name="ServiceBinding" maxBufferPoolSize="1000000" maxReceivedMessageSize="1000000"> <readerQuotas maxDepth="1000000" maxStringContentLength="1000000" maxArrayLength="1000000" maxBytesPerRead="1000000" maxNameTableCharCount="1000000" /> </binding> </webHttpBinding> </bindings> </system.serviceModel> How can I make it possible for my users to access my webservice also when using only domain.com?

  • TimeOuts with HttpWebRequest when running Selenium concurrently in .NET

    - by domsom
    I have a download worker that uses ThreadPool-threads to download files. After enhancing these to apply some Selenium tests to the downloaded files, I am constantly experiencing TimeOut-exceptions with the file downloaders and delays running the Selenium tests. More precisely: When the program starts, the download threads start downloading and a couple of pages are seamlessly processed via Selenium Shortly after, the first download threads start throwing TimeOut exceptions from HttpWebRequest. At the same time, commands stop flowing to Selenium (as observed in the SeleniumRC log), but the thread running Selenium is not getting any exception This situation holds as long as there are entries in the download list: new download threads are being started and terminate after receiving TimeOuts (without trying to lock Selenium) As soon as no more download threads are being started, Selenium starts receiving commands again and the threads waiting for the lock are processed sequentially as designed Now here's the download code: HttpWebRequest request = null; WebResponse response = null; Stream stream = null; StreamReader sr = null; try { request = (HttpWebRequest) WebRequest.Create(uri); request.ServicePoint.ConnectionLimit = MAX_CONNECTIONS_PER_HOST; response = request.GetResponse(); stream = response.GetResponseStream(); // Read the stream... } finally { if (request != null) request.Abort(); if (response != null) response.Close(); if (stream != null) { stream.Close(); stream.Dispose(); } if (sr != null) { sr.Close(); sr.Dispose(); } } And this is how Selenium is used afterwards in the same thread: lock(SeleniumLock) { selenium.Open(url); // Run some Selenium commands, but no selenium.stop() } Where selenium is a static variable that is initialized in the static constructor of the class (via selenium.start()). I assume I am running into the CLR connection limit, so I added these lines during initalization: ThreadPool.GetMaxThreads (out maxWorkerThreads, out maxCompletionPortThreads); HttpUtility.MAX_CONNECTIONS_PER_HOST = maxWorkerThreads; System.Net.ServicePointManager.DefaultConnectionLimit = maxWorkerThreads + 1; The + 1 is for the connection to the SeleniumRC, due to my guess that the Selenium client code also uses HttpWebRequest. It seems like I'm still running into some kind of deadlock - although the threads waiting for the Selenium lock do not hold any resources. Any ideas on how to get this working?

  • Getting 404 when attempting to POST file to Google Cloud Storage from service account

    - by klactose
    I'm wondering if anyone can tell me the proper syntax & formatting for a service account to send a POST Object to bucket request? I'm attempting it programmatically using the HttpComponents library. I manage to get a token from my GoogleCredential, but every time I construct the POST request, I get: HTTP/1.1 403 Forbidden <?xml version='1.0' encoding='UTF-8'?><Error><Code>AccessDenied</Code><Message>Access denied.</Message><Detailsbucket-name</Details></Error The Google documentation that describes the request methods, mentions posting using html forms, but I'm hoping that wasn't suggesting the ONLY way to get the job done. I know that HttpComponents has a way to explicitly create form data by using UrlEncodedFormEntity, but it doesn't support multipart data. Which is why I went with using the MultipartEntity class. My code is below: MultipartEntity entity = new MultipartEntity( HttpMultipartMode.BROWSER_COMPATIBLE ); String token = credential.getAccessToken(); entity.addPart("Authorization", new StringBody("OAuth " + token)); String date = formatDate(new Date()); entity.addPart("Date", new StringBody(date)); entity.addPart("Content-Encoding", new StringBody("UTF-8")); entity.addPart("Content-Type", new StringBody("multipart/form-data")); entity.addPart("bucket", new StringBody(bucket)); entity.addPart("key", new StringBody("fileName")); entity.addPart("success_action_redirect", new StringBody("/storage")); File uploadFile = new File("pathToFile"); FileBody fileBody = new FileBody(uploadFile, "text/xml"); entity.addPart("file", fileBody); httppost.setEntity(entity); System.out.println("Posting URI = "+httppost.toString()); HttpResponse response = client.execute(httppost); HttpEntity resp_entity = response.getEntity(); As I mentioned, I am able to get an actual token, so I'm pretty sure the problem is in how I've formed the request as opposed to not being properly authenticated. Keep in mind: This is being performed by a service account. Which means that it does have Read/Write access Thanks for reading, and I appreciate any help!

  • Generic class for performing mass-parallel queries. Feedback?

    I don't understand why, but there appears to be no mechanism in the client library for performing many queries in parallel for Windows Azure Table Storage.
