  • Lucene.net create+lock errors in ASP.NET

    - by acidzombie24
    I have an issue with Lucene.net. It throws a lock exception. After poking around i notice these things. My code below works in an app bit when calling in Application_Start i get a NoSuchDirectoryException. Not closing the writer (as my code doesnt do below) i WILL get a LockObtainFailedException with the message Lock obtain timed out: SimpleFSLock@<FULL_PATH> from either app or asp.net These thread hinted when spawning threads they get less permissions then i do (but! my main thread has problems as well...) and one solution is to impersonate IIS. I am using visual studios 2010. I am not sure how full blown it is but my attempt to impersonate it failed. So my question is how do i have lucene create the directory and not throw an exception if dont close the writer for some reason (such as power going out)? http://stackoverflow.com/questions/2341163/why-is-my-lucene-index-getting-locked/2499285#2499285 http://stackoverflow.com/questions/1123517/lucene-net-and-i-o-threading-issue/1123981#1123981 static IndexWriter writer = null; static void lucene_init() { bool create = false; string dirname = "LuceneIndex_z"; if (System.IO.Directory.Exists(dirname) == false) create = true; var directory = FSDirectory.GetDirectory(dirname); var analyzer = new StandardAnalyzer(); writer = new IndexWriter(directory, analyzer, create); }

  • silverlight master-detail with two listboxes in pure xaml with ria services throwing exception

    - by Sam
    Hi, I was trying to achieve master-detail with 2 ListBox, 2 DomainDataSource and a IValueConverter, when entering the page it throws the random error it does when your xaml is invalid: "AG_E_PARSER_BAD_PROPERTY_VALUE [Line: 24 Position: 61]" Which is in fact the start position of where I am binding the listbox selected item with converter to the parameter's value of my DomainDataSource. I would love to achieve this by pure xaml, I did it by code behind and that works but I don't like it :p When the parameter is a hard-coded integer 1, it works, so I assume it's the value binding My code is below here, thanks in advance for at least looking :) (taken into accound all the xmlns's & usings are correct) Xaml: <Grid x:Name="LayoutRoot"> <Grid.Resources> <helpers:ListItemtoIdListValueConverter x:Key="mListConverter" /> </Grid.Resources> <riacontrols:DomainDataSource x:Name="GetLists" DomainContext="{StaticResource DbContext}" LoadSize="20" QueryName="GetLists" AutoLoad="True" /> <riacontrols:DomainDataSource x:Name="GetListItems" DomainContext="{StaticResource DbContext}" LoadSize="20" QueryName="GetListItemsById" AutoLoad="True"> <riacontrols:DomainDataSource.QueryParameters> <riadata:Parameter ParameterName="id" Value="{Binding ElementName=ListBoxLists, Path=SelectedItem, Converter={StaticResource mListConverter}}" /> </riacontrols:DomainDataSource.QueryParameters> </riacontrols:DomainDataSource> <activity:Activity IsActive="{Binding IsBusy, ElementName=ListBoxListItems}"> <StackPanel Orientation="Horizontal"> <ListBox x:Name="ListBoxLists" ItemsSource="{Binding Data, ElementName=GetLists, Mode=OneWay}" Width="150" Margin="0,0,10,10" /> <ListBox x:Name="ListBoxListItems" ItemsSource="{Binding Data, ElementName=GetListItems, Mode=OneWay}" Width="150" Margin="0,0,10,10" /> </StackPanel> </activity:Activity> </Grid> IValueConverter: public class ListItemtoIdListValueConverter: IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { list mList = (list)value; if (mList != null) return mList.id; else return null; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } #endregion }

  • How to avoid coupling when using regions in Composite WPF

    - by emddudley
    I have an application designed using Microsoft's Composite Application Library. My shell has several regions defined so that I can inject content from separate modules. I'm looking for a design pattern that will reduce the coupling that these regions introduce. In all examples I have seen, regions are defined and accessed using a string in a static class in the infrastructure project.: <ItemsControl cal:RegionManager.RegionName="{x:Static inf:RegionNames.TabRegion}"> public static class RegionNames { public const string TabRegion = "TabRegion"; } This introduces an dependency on the shell from the infrastructure project, because the infrastructure project is now defining some of the shell's capabilities. The CAL RegionManager throws an exception if you attempt to access a region which is not defined, so I must ensure that the infrastructure and shell projects are kept in sync. Is there a way to isolate the shell's regions so that they are defined only within the shell (no region names in the infrastructure project)? Is there a way to make regions optional, so that shells can be swapped out even if they don't have all the same regions? (An example: One shell has menu and toolbar regions, another only has the menu... modules should be able to inject into the toolbar if it's available, without failing when it's not)

  • Laravel - Paginate and get()

    - by Bajongskie
    With the code below, what I wanted was paginate the query I created. But, when I try to add paginate after get, it throws an error. I wanted to remain get since I want to limit to columns that was set on $fields. What would should be the better idea to paginate this thing? or what's a good substitute for get and limit the columns? What I tried: ->get($this->fields)->paginate($this->limit) Part of my controller: class PhonesController extends BaseController { protected $limit = 5; protected $fields = array('Phones.*','manufacturers.name as manufacturer'); /** * Display a listing of the resource. * * @return Response */ public function index() { if (Request::query("str")) { $phones = Phone::where("model", 'LIKE', '%'. Request::query('str') . '%') ->join('manufacturers', 'manufacturers_id', '=', 'manufacturers.id') ->get($this->fields); } else { $phones = Phone::join('manufacturers', 'manufacturers_id', '=', 'manufacturers.id') ->get($this->fields); } return View::make('phones.index')->with('phones', $phones); } }

  • Problems requesting the LDAP: The server is unwilling to process the request.

    - by Flo
    We have written an authentication provider for a SharePoint web application which can requests multiple LDAP directories. One of the LDAP server have to be requested via SSL. So we imported the CA certificate which was used to sign the LDAP server's certificate into the certificate store of the SharePoint server. The following code snippet shows how we authenticate an user. The passed credentials (account, password) belong to the user we want to authenticate. var entry = new DirectoryEntry("LDAP://<ldap-server-address>", "cn=account,ou=sub,o=xyz,c=de", "password", AuthenticationTypes.SecureSocketsLayer); var searcher = new DirectorySearcher(entry); var found = searcher.FindOne(); When the code is processed, the call to searcher.FindOne() throws following exception. System.Runtime.InteropServices.COMException (0x80072035): The server is unwilling to process the request What circumstance can lead to this error? UPDATE: I found some information about the error message. There the problem seems to be the certificate store, as the user has only stored the certificate in the in the user's store and not in the computer's store. Unfortunately we've already stored it there. So could this be still a certificate issue? UPDATE/SOLUTION: Actually the problem is solved. It seems as if the root CA certificate was imported correctly but the error messages the LDAP server responded was caused by an expired user account our customer gave us for testing.

  • powershell / runspace in a thread

    Hello ! I'm running the following code : RunspaceConfiguration config = RunspaceConfiguration.Create(); PSSnapInException warning; config.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out warning); if (warning != null) throw warning; Runspace thisRunspace = RunspaceFactory.CreateRunspace(config); thisRunspace.Open(); string alias = usr.AD.CN.Replace(' ', '.'); string letter = usr.AD.CN.Substring(0, 1); string email = alias + "@" + (!usr.Mdph ?

When in a thread it throws the following exception : ObjectDisposedException "The safe handle has been closed." (Translated from french) I then replaced "Open" wirh "OpenAsync" which helped not getting the previous exception. But when on Invoke I get the following exception : InvalidRunspaceStateException "Unable to call the pipeline because its state of execution is not Opened. Its current state is Opening." (Also translated from french) I'm clueless... Any help welcome !!! Thanks !!!

  • PInvoke Unbalances the stack

    - by Giawa
    Good afternoon, I have been working on a dll that can use CORBA to communicate to an application that is network aware. The code works fine if I run it as a C++ console application. However, I have gotten stuck on exporting the methods as a dll. The methods seems to export fine, and if I call a method with no parameters then it works as expected. I'm hung up on passing a C# string to a C++ method. My C++ method header looks like this: bool __declspec(dllexport) SpiceStart(char* installPath) My C# DLL import code is as follows: [DllImportAttribute("SchemSipc.dll", CharSet=CharSet.Ansi)] private static extern bool SpiceStart(string installPath); I call the method like so: bool success = SpiceStart(@"c:\sedatools"); The call to SpiceStart throws the exception "PInvokeStackImbalance", which "is likely because the managed PInvoke signature does not match the unmanaged target signature." Does anyone have any suggestions? If I remove the char* and string from the parameters, then the method runs just fine. However, I'd like to be able to pass the installation path of the application to the dll from C#. Thanks in advance, Giawa

  • WPF Repeater (like) control for collection source??

    - by Sonic Soul
    I have a WPF DataGrid bound to ObservableCollection. Each item in my collection has Property which is a List. In my row details pane, i would like to write out formatted textblocks for each item in this collection. The end result would be something equivalent to: <TextBlock Style="{StaticResource NBBOTextBlockStyle}" HorizontalAlignment="Right"> <TextBlock.Inlines> <Run FontWeight="Bold" Text="{Binding Path=Exchanges[0].Name}" /> <Run FontWeight="Bold" Text="{Binding Path=Exchanges[0].Price}" /> <LineBreak /> <Run Foreground="LightGray" Text="{Binding Path=Exchanges[0].Quantity}" /> </TextBlock.Inlines> </TextBlock> <TextBlock Style="{StaticResource NBBOTextBlockStyle}"> <TextBlock.Inlines> <Run FontWeight="Bold" Text="{Binding Path=Exchanges[1].Name}" /> <Run FontWeight="Bold" Text="{Binding Path=Exchanges[1].Price}" /> <LineBreak /> <Run Foreground="LightGray" Text="{Binding Path=Exchanges[1].Quantity}" /> </TextBlock.Inlines> </TextBlock> and so on 0-n times. I've tried using ItemsControl for this: <ItemsControl ItemsSource="{Binding Path=Exchanges}"> <DataTemplate> <Label>test</Label> </DataTemplate> </ItemsControl> however, this appears to be only meant for more static sources, as it throws the following exception (collection is not altered after creation): ItemsControl Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead Is there another way to achieve this?

  • How do you write Valid XHTML 1.0 Strict code when you are using javascript to fill an element that r

    - by Tim Visher
    I'm running my site through the W3C's validator trying to get it to validate as XHTML 1.0 Strict and I've gotten down to a particularly sticky (at least in my experience) validation error. I'm including certain badges from various services in the site that provide their own API and code for inclusion on an external site. These badges use javascript (for the most part) to fill an element that you insert in the markup which requires a child. This means that in the end, perfectly valid markup is generated, but to the validator, all it sees is an incomplete parent-child tag which it then throws an error on. As a caveat, I understand that I could complain to the services that their badges don't validate. Sans this, I assume that someone has validated their code while including badges like this, and that's what I'm interested in. Answers such as, 'Complain to Flickr about their badge' aren't going to help me much. An additional caveat: I would prefer that as much as possible the markup remains semantic. I.E. Adding an empty li tag or tr-td pair to make it validate would be an undesirable solution, even though it may be necessary. If that's the only way it can be made to validate, oh well, but please lean answers towards semantic markup. As an example: <div id="twitter_div"> <h2><a href="http://twitter.com/stopsineman">@Twitter</a></h2> <ul id="twitter_update_list"> <script type="text/javascript" src="http://twitter.com/javascripts/blogger.js"></script> <script type="text/javascript" src="http://twitter.com/statuses/user_timeline/stopsineman.json?callback=twitterCallback2&amp;count=1"></script> </ul> </div> Notice the ul tags wrapping the javascript. This eventually gets filled in with lis via the script, but to the validator it only sees the unpopulated ul. Thanks in advance!

  • Handling exception from unmanaged dll in C#

I haven't seen enough Silverlight yet and I cannot find a close enough example that it makes sense to me.

  • validate that URI is valid http URI

    - by Alfred
    Hi all, My problem: First of hopefully this is not a duplicate, but I could not find the right answer(right away). I would like to validate that an URI(http) is valid in Java. I came up with the following tests but I can't get them to pass. First I used getPort(), but then http://www.google.nl will return -1 on getPort(). This are the test I want to have passed Test: @Test public void testURI_Isvalid() throws Exception { assertFalse(HttpUtils.validateHTTP_URI("ttp://localhost:8080")); assertFalse(HttpUtils.validateHTTP_URI("ftp://localhost:8080")); assertFalse(HttpUtils.validateHTTP_URI("http://localhost:8a80")); assertTrue(HttpUtils.validateHTTP_URI("http://localhost:8080")); final String justWrong = "/schedule/get?uri=http://localhost:8080&time=1000000"; assertFalse(HttpUtils.validateHTTP_URI(justWrong)); assertTrue(HttpUtils.validateHTTP_URI("http://www.google.nl")); } This is what I came up with after I removed the getPort() part but this does not pass all my unit tests. Production code: public static boolean validateHTTP_URI(String uri) { final URI u; try { u = URI.create(uri); } catch (Exception e1) { return false; } return "http".equals(u.getScheme()); } This is the first test that is failing because I am no longer validating the getPort() part. Hopefully somebody can help me out. I think I am not using the right class to validate url's?? P.S: I don't want to connect to the server to validate the URI is correct. At least not yet in this step. I only want to validate scheme.

  • Struts2 - How to use the Struts2 Annotations?

    I'm trying to implement the Struts 2 Annotations in my project, but I don't know how.

My Action package org.apache.struts.helloworld.action; import org.apache.struts.helloworld.model.MessageStore; import com.opensymphony.xwork2.ActionSupport; import org.apache.struts2.convention.annotation.Result; import org.apache.struts2.convention.annotation.Results; @Results({ @Result(name="success", location="HelloWorld.jsp") }) public class HelloWorld extends ActionSupport { public String execute() throws Exception { messageStore = new MessageStore() ; return SUCCESS; } The jsp page from where I'm trying to use my action. <body> <h1>Welcome To Struts 2!</h1> <p><a href="<s:url action='helloWorld'/>">Hello World</a></p> </body> When I press the link associated to the action helloWorld, but it's sends me to the exactly the same page. So, from index.jsp, it's sends to index.jsp. The way it should behave: it should send me to HelloWorld.jsp. I uploaded the project (a very simple HelloWorld app) to FileFront, maybe someone sees where is the problem. http://www.filefront.com/16364385/Hello_World.zip

  • Castle MonoRail ARDataBind trying to bind to non-existent row

    - by dave thieben
    I have a shopping cart application running on MonoRail and using Castle ActiveRecord/NHibernate, and there is a ShoppingCart table and a ShoppingCartItems table, which are mapped to entities. Here's the scenario: a user adds things to the shopping cart, say 5 items, and goes to view the cart. The cart shows all 5 items. the user duplicates the tab/window and gets another tab of the same cart (call it tab B). the user removes an item from the cart, so now there are 4 items in tab B, but in the original tab A, there are still 5 items. the user goes back to tab A, and updates something in the cart and clicks the "update" button which submits the changes. my MonoRail action tries to do an ARDataBind on ShoppingCartItems using the data from the view, which includes all 5 items. when it gets to the item that the user deleted from tab B, it throws a "No row with the given identifier exists" for that item. I can't figure out if there is a way to have it not bind that row, return null, return new instance, etc.? there is an AutoLoadBehavior parameter on the ARDataBind attribute, but that appears to only affect loading of child entities, and not the root entity. regardless of which option I choose, I get the exception before control even enters the action method (except AutoLoadBehavior.Never, but that doesn't really help me). instead, I have code that calls Request.ObtainParamsNode() to pull the form nodes and parse them manually into objects, and ignores the ones that no longer exist. is there a better way? thanks.

  • Why are my installed fonts not available in .NET?

    - by Dan Herbert
    I'm trying to render some images with text using a font I just added to my machine and no matter what I do, I can't seem to get the font to become accessible in .NET. I tried using PrivateFontCollection.AddFontFile(filename) and PrivateFontCollection.AddMemoryFont(...) to load the font into memory. Whenever I do this, the method throws a "File Not Found" exception, which is unusual because I get this exception when loading the font from memory, where there should be no files to be "not found". Initially, I thought it may be because the font I was trying to use was in the .pfm format, so I converted the font to .otf and had the same problem. Then I tried installing the .otf font to my Windows Fonts folder so I could pull it from FontFamily.Families. Once I installed the font, it became available in Microsoft Word & Notepad2. However, when I try to load it from FontFamily.Families, it is not included in the array. I thought rebooting my machine would fix the issue but obviously there is something more complicated involved here. Is there something basic I just might have missed when installing the font in my machine (Windows Vista), or is there another way to programmatically load a font that I should be using instead? Is .otf not supported in .NET?

    I am developing an Excel 2003 add-in using Visual Studio 2008. My add-in loads fine; however, it loads plug-ins from other C# DLL's. I would like this to be done dynamically at run time so referencing them during development is something I would rather not do. Anyways, anytime I try to load a DLL from the Excel add-in at start up, it throws a security exception. This particular example is HTML Agility Pack. It's not a plug-in but a plug-in's dependency. But nonetheless it won't even load: {System.IO.FileLoadException: Could not load file or assembly 'HtmlAgilityPack, Version=1.4.0.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418) File name: 'HtmlAgilityPack, Version=1.4.0.0, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a' ---> System.Security.Policy.PolicyException: Execution permission cannot be acquired. at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Boolean checkExecutionPermission) at System.Security.SecurityManager.ResolvePolicy(Evidence evidence, PermissionSet reqdPset, PermissionSet optPset, PermissionSet denyPset, PermissionSet& denied, Int32& securitySpecialFlags, Boolean checkExecutionPermission) at System.Reflection.Assembly.nLoadFile(String path, Evidence evidence) at System.Reflection.Assembly.LoadFile(String path) at Cjack.Druid.SourcePluginManager.LoadPlugin(String filePath) in C:\Documents and Settings\Annie Tormey\My Documents\Visual Studio 2008\Projects\DruidAddin2003\Druid\SourcePluginManager.cs:line 26 } This is extremely frustrating because it runs perfectly fine for Office 2010 and as a standalone application. Thank-you to anyone who can give me an answer as to why this is happening or a solution to fix it. Thank-you for your time.

  • Problem with conversion of existing project to Silverlight 4

    - by derklaus
    We have a working Silverlight 3 project. After changing the target framework to Silverlight 4 the application won't start anymore. It throws an exception in the following line in the generated InitializeComponent() method: System.Windows.Application.LoadComponent(this, new System.Uri("/SLAppMain;component/App.xaml", System.UriKind.Relative)); Here is the exception (note the inner exception): System.Windows.Markup.XamlParseException occurred Message= [Line: 0 Position: 0] LineNumber=0 LinePosition=0 StackTrace: bei System.Windows.Application.LoadComponent(Object component, Uri resourceLocator) InnerException: System.TypeLoadException Message=Der Typ 'System.Security.AllowPartiallyTrustedCallersAttribute' konnte nicht aus der mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e -Assembly geladen werden.

  • codeigniter & cjax framework, fatal error class 'CI_Controller' not found

    - by Martin
    I'm having this weird error with Codeigniter 2.1.3 and latest cjax for codeigniter. Weird thing is, when I download the latest codeigniter, and latest cjax framework for codeitniger and copy to my friends server, and call: domain.com/ajax.php?test/test2 to show the test ajax examples ... it works like a breeze, but when I do this on my server, I get server error (even tho, we both have same php version and such). Server then throws in error log file this error: PHP Fatal error: Class 'CI_Controller' not found in /hosting/www/domain.com/www/application/response/test.php on line 3 Now, I've read thru stackoverflow with people having this problem and solving by changing the construct and calling CI_Controller instead of Controller. But I already do that ... - I mean it's in the basic example that is suppose to work without touching the code, and it does, just not on my domain for some crappy reason. Ajax.php from cjax framework for codeingter should load controller from folder response, named test and call function test2, which looks like this (the actual file named test.php): class Test extends CI_Controller { function __construct() { parent::__construct(); } /** * * ajax.php?test/test/a/b/c * * @param unknown_type $a * @param unknown_type $b * @param unknown_type $c */ function test($a = null,$b = null, $c = null) { $this->load->view('test', array('data' => $a .' '.$b.' '.$c)); } /** * ajax.php?test/test2 * * Here we are testing out the javascript library. * * Note: the library it is not meant to be included in ajax controllers - but in front-controllers, * it is being used here for the sake of simplicity in testing. */ function test2() { $ajax = ajax(); $ajax->update('response','Cjax Works'); $ajax->append('#response','<br /><br />version: '.$ajax->version); $ajax->success('Cjax was successfully installed.', 5); //see application/views/test2.php $this->load->view('test2'); } I was hoping someone could bring some light into this problem - or maybe someone has already experienced it? Thanks for your time! Mart

  • vbCrLf in Multiline TextBox shows up only when .Trim() is called

    - by Brandon Montgomery
    I have an ASP TextBox with TextMode set to MultiLine. I'm having problems with preserving the vbCrLf characters when a user tries to put line breaks into the text. When a button on the page is pressed, I'm taking the text from the control, trimming it using String.Trim, and assigning that value to a String property on an object (which, in turn assigns it to a private internal String variable on the object). The object then takes the value from the private internal variable and throws it into the database using a stored procedure call (the SP parameter it is put into is an nvarchar(4000)). ASPX Page: <asp:UpdatePanel ID="UpdatePanel2" runat="server" RenderMode="Inline" UpdateMode="Conditional" ChildrenAsTriggers="true"> <ContentTemplate> <!-- some other controls and things --> <asp:TextBox TextMode="MultiLine" runat="server" ID="txtComments" Width="100%" Height="60px" CssClass="TDTextArea" Style="border: 0px;" MaxLength="2000" /> <!-- some other controls and things --> </ContentTemplate> </asp:UpdatePanel> code behind: ProjectRequest.StatusComments = txtComments.Text.Trim object property: Protected mStatusComments As String = String.Empty Property StatusComments() As String Get Return mStatusComments.Trim End Get Set(ByVal Value As String) mStatusComments = Value End Set End Property stored proc call: Common.RunSP(mDBConnStr, "ProjectStatusUpdate", _ Common.MP("@UID", SqlDbType.NVarChar, 40, mUID), _ Common.MP("@ProjID", SqlDbType.VarChar, 40, mID), _ Common.MP("@StatusID", SqlDbType.Int, 8, mStatusID), _ Common.MP("@Comments", SqlDbType.NVarChar, 4000, mStatusComments), _ Common.MP("@PCTComp", SqlDbType.Int, 4, 0), _ Common.MP("@Type", Common.TDSqlDbType.TinyInt, 1, EntryType)) Here's the strangest part. When I debug the code, if I type "test test" (without the quotes) into the comments text box, then click the save button and use the immediate window to view the variable values as I step through, here is what I get: ?txtComments.Text "test test" ?txtComments.Text.Trim "test test" ?txtComments.Text(4) " "c ?txtComments.Text.Trim()(4) " "c Anyone have a clue as to what's going on here?

  • How to detect running on WebSphere

    - by Pedro Guedes
    Hi, I'm building a webapp that should run on both Tomcat and WebSphere and I've managed to make almost all the differences into properties with default values that I can override for deployment on the Tomcat server. I need to do yet another override for the authentication provider bean... public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException { if(isWebSphere()){ LOG.warn("Running on WebSphere... not overriding default authentication mechanism."); return; } LOG.info("Running on Tomcat... overriding authentication provider bean ("+AUTHENTICATION_PROVIDER_BEAN+")"); if (beanFactory.containsBean(AUTHENTICATOR_BEAN) && beanFactory.containsBean(POPULATOR_BEAN) && beanFactory.containsBean(USERDETAIL_PROVIDER_BEAN)){ LdapAuthenticator authenticator = (LdapAuthenticator) beanFactory.getBean(AUTHENTICATOR_BEAN); LdapAuthoritiesPopulator populator = (LdapAuthoritiesPopulator) beanFactory.getBean(POPULATOR_BEAN); UserDetailProvider userDetailProvider = (UserDetailProvider) beanFactory.getBean(USERDETAIL_PROVIDER_BEAN); ExtendedLdapAuthenticationProvider override = new ExtendedLdapAuthenticationProvider(authenticator, populator); override.setUserDetailProvider(userDetailProvider); beanFactory.registerSingleton(AUTHENTICATION_PROVIDER_BEAN, override); } else { throw new BeanCreationException("Could not find required beans to assemble overriding object for authentication..."); } } Now my problem is how to implement the isWebSphere() method. I was thinking Class.forName("someWebSphereSpecific"), but is there a better way?

  • OpenCV Python HoughCircles error

    - by Dan
    Hi, I'm working on a program that detects circular shapes in images. I decided a Hough Transform would be the best, and I found one in the OpenCV library. The problem is that when I try to use it I get an error that I have no idea how to fix. Is OpenCV for Python not fully implemented? Is there a fix to the library I need for the program to work? Here's the code: import cv #cv.NamedWindow("camera", 1) capture = cv.CaptureFromCAM(0) while True: img = cv.QueryFrame(capture) gray = cv.CreateImage(cv.GetSize(img), 8, 1) edges = cv.CreateImage(cv.GetSize(img), 8, 1) cv.CvtColor(img, gray, cv.CV_BGR2GRAY) cv.Canny(gray, edges, 50, 200, 3) cv.Smooth(gray, gray, cv.CV_GAUSSIAN, 9, 9) storage = cv.CreateMat(1, 2, cv.CV_32FC3) #This is the line that throws the error cv.HoughCircles(edges, storage, cv.CV_HOUGH_GRADIENT, 2, gray.height/4, 200, 100) #cv.ShowImage("camera", img) if cv.WaitKey(10) == 27: break And here is the error I'm getting: OpenCV Error: Null pinter () in unknown function, file ..\..\..\..\ocv\openc\src\cxcore\cxdatastructs.cpp, line 408 Traceback (most recent call last): File "ellipse-detect-webcam.py", line 20, in cv.HoughCircles(edges, storage, cv.CV_HOUGH_GRADIENT, 2, gray.height/4, 200, 100) cv.error Thanks in advance for the help.
