  • how did i break :method -> :delete

    - by Tallboy
    i refactored my entire application and gave it a whole new design. The one thing that seems to be broken is all the original link_to methods I had which were :method = :delete are now getting sent as a GET request. The only thing I did that I can remember that might cause it is delete jquery-rails from the gemfile (I'm just getting it from google ajax). Does anyone have any other ideas what I could have deleted?

  • MVC2 JSON action, if I want to be RESTful should I allow GET, POST, or Both?

    - by Yads
    The project I'm currently working has a whole bunch of JSON actions in order to populate cascading dropdowns via ajax calls. Since they're technically Select queries and we're trying to be RESTful, we've been marking these actions with the HttpGet attributes. However by default, JsonResultdoes not allow to return results via a GET. So we've had to explicitly call Json(data, JsonRequestBehavior.AllowGet). What I'm wondering is, is this bad practice? Should we only be allowing Post requests to our Json actions? If it makes a difference, this is an enterprise application, that requires a log in to a particular environment before it can be accessed.

  • RESTful API: How to model JSON representation?

    - by Jan P.
    I am designing a RESTful API for a booking application. You can request a list of accommodations. And that's where I don't really know how to design the JSON represenation. This is my XML representation: <?xml version="1.0" encoding="utf-8"?> <accommodations> <accommodation> <name>...</name> <category>couch</category> </accommodation> <accommodation> <name>...</name> <category>room</category> </accommodation> <accommodations> My first try to convert this to JSON resulted in this output (1): { "0": { "name": "...", "category": "couch" }, "1": { "name": "...", "category": "room" } } But as I looked how others APIs did it, I found something looking more like this (2): [ { "name": "...", "category": "couch" }, { "name": "...", "category": "room" } ] I know version 1 is an object, and version 2 an array. But which one is better in this case?

  • RESTful web service, PUTting an unnamed resource?

    - by James L
    I have a back-end service that creates unique identifiers for resources. The general idea is that resources are saved and versioned, so you can perform: GET http://service/sales/targets/7818181919/latest or GET http://service/sales/targets/7818181919/4 for version 4, and so on. My question is about the most correct way to upload these resources in the first place. How about: PUT http://service/sales/targets/ returning 303 See other /service/sales/targets/ It seems a little wrong as you should PUT and GET from exactly the same place using a resource-oriented interface, but I can't think of a better option. Any ideas?

  • Should an edit of a comment be sent through POST or PUT?

    - by the_drow
    I have the following URI: Posts/{postId}/Comments/{commentId} I would like to enable users to edit a comment through my API, should the edit be done with POST or PUT? One one hand, POST updates the contents of a resource so that makes sense but on the other hand PUT replaces it with a new one. So if I understand correctly with POST I need to send only what needs to be updates and with PUT I send the whole resource. Usually in edit forms, the whole resource is loaded anyway so what's the point of using POST? If I take one approach or the other, what are the differences?

  • RESTful enums. string or Id?

    - by GazTheDestroyer
    I have a RESTful service that exposes enums. Should I expose them as localised strings, or plain integers? My leaning is toward integers for easy conversion at the service end, but in that case the client needs to grab a list of localised strings from somewhere in order to know what the enums mean. Am I just creating extra steps for nothing? There seems to be little information I can find about which is commonly done in RESTful APIs. EDIT: OK. Let's say I'm writing a website that stores information about people's pets. I could have an AnimalType enum 0 Dog 1 Cat 2 Rabbit etc. When people grab a particular pet resource, say /pets/1, I can either provide a meaningful localised string for the animal type, or just provide the ID and force them to do another look up via a /pets/types resource. Or should I provide both?

  • Restful client on Codeigniter issue

    - by user1852837
    This is weird. I don't know what is problem on my website. My website works on local server but not on live server. Login page works on first signin but after logout then re-login again message says: "invalid username and password" since it works on first attempt. I found out when I debugging that http://xxxxx.com/api/authentication/sign not found. It display 404 page not found. Sometimes you can login and sometimes not. In my local it works. I contact the web server admin and I ask what is the status of the session on the server and How does it execute it's web requests? (Sockets, file_get_contents, curl?). They said that No problems reproduced with Server Sessions and PHP Curl works fine. I know it's weird but can somebody here can figure it out what is the problem behind of it.

  • How to solve "The ChannelDispatcher is unable to open its IChannelListener" error?

    - by kyrisu
    Hi, I'm trying to communicate between WCF hosted in Windows Service and my service GUI.

  • How to serialize parameters in Web Service method

    - by Georgi
    Hi, I have this problem. I have WCF .Net C# web service with this method: public interface IMyService { // TODO: Add your service operations here [OperationContract] ListOfRequests GetListOfRequests(string par1, string par2, string par3, DateTime par4, DateTime par5, string par6, string par7); } public class MyService : IMyService { public ListOfRequests GetListOfRequests(string par1, string par2, string par3, DateTime par4, DateTime par5, string par6, string par7) { // .... web method code here; } } The problem is that when I generate the web service the wsdl schema return this: <xs:element name="GetListOfRequests"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="par1" nillable="true" type="xs:string" /> <xs:element minOccurs="0" name="par2" nillable="true" type="xs:string" /> <xs:element minOccurs="0" name="par3" nillable="true" type="xs:string" /> <xs:element minOccurs="0" name="par4" type="xs:dateTime" /> <xs:element minOccurs="0" name="par5" type="xs:dateTime" /> <xs:element minOccurs="0" name="par6" nillable="true" type="xs:string" /> <xs:element minOccurs="0" name="par7" nillable="true" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> and I want my parameters to be not null like this: <xs:element name="GetListOfRequests"> <xs:complexType> <xs:sequence> <xs:element minOccurs="1" name="par1" nillable="false" type="xs:string" /> <xs:element minOccurs="1" name="par2" nillable="false" type="xs:string" /> <xs:element minOccurs="1" name="par3" nillable="false" type="xs:string" /> <xs:element minOccurs="1" name="par4" type="xs:dateTime" /> <xs:element minOccurs="1" name="par5" type="xs:dateTime" /> <xs:element minOccurs="1" name="par6" nillable="false" type="xs:string" /> <xs:element minOccurs="0" name="par7" nillable="true" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> How can I serizalize parameters to achieve this?

  • Svcutil generating bad config with multiple endpoints

    - by vfilby
    I have a WCF service that has exposed a soap and an xml endpoint. When I use svcutil to generate the proxy code on the client side the generated configuration contains two endpoints which causes the client to fail. If I edit the web.config file and remove the second endpoint (with the custom binding) all works as expected. Is there a way I can get svcutil to generate a config that just works so that I don't need to hand edit the file everytime? Client-side error: An endpoint configuration section for contract 'MyNamespace.ITestService' could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name.

  • KISS: Simple C# application which communicates with a RESTful web service.

    - by Workshop Alex
    Following the KISS principle, I suddenly realised the following: In .NET, you can use the Entity Model Framework to wrap around a database. This model can be exposed as a web service through WCF. This web service would have a very standardized definition. A client application could be created which could consume any such RESTful web service. I don't want to re-invent the wheel and it wouldn't surprise me if someone has already done this, so my question is simple: Has anyone already created a simple (desktop, not web) client application that can consume a RESTful service that's based on the Entity Framework and which will allow the user to read and write data directly to this service? Otherwise, I'll just have to "invent" this myself. :-)Problem is, the database layer and RESTful service is already finished. The RESTful service will only stay in the project during it's development phase, since we can use the database-layer assembly directly from the web applications that are build around it. When the web application is deployed, the RESTful services are just kept out of the deployment. But the database has a lot of data to manage over nearly 50 tables. When developing against a local database, we can have straight access to the database so I wouldn't need this tool for this. When it's deployed, the web application would be the only way to access the data so I could not use this tool. But we're also having a test phase where the database is stored on another system outside the local domain and this database is not available for developers. Only administrators have direct access to this database, making tests a bit more complex. However, through the RESTful service, I can still access the data directly. Thus, when some test goes wrong, I can repair the data through this connection or just create a copy of the data for tests on my local system. There's plenty of other functionality and it's even possible to just open the URL to a table service straight in Excel or XMLSpy to see the contents. But when I want to write something back, I have to write special code to do just that. A generic tool that would allow me to access the data and modify it would be easier. Since it's a generic setup around the ADO.NET Data services, this should be reasonable easy too. Thus, I can do it but hoped someone else has already done something similar. But it appears that there's no such tool made yet...

  • Xml reader creation problem

  • .NET unit test runner outputting FaultException.Detail

    - by Adam
    Hello, I am running some unit tests on a WCF service. The service is configured to include exception details in the fault response (with the following in my service configuration file). <serviceDebug includeExceptionDetailInFaults="true" /> If a test causes an unhandled exception on the server the fault is received by the client with a fully populated server stack trace. I can see this by calling the exception's ToString() method. The problem is that this doesn't seem to be output by any of the test runners that I have tried (xUnit, Gallio, MSTest). They appear to just output the Message and the StackTrace properties of the exception. To illustrate what I mean, the following unit test run by MSTest would output three sections: Error Message Error Stack Trace Standard Console Output (contains the information I would like, e.g. "Fault Detail is equal to An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is: ..." try { service.CallMethodWhichCausesException(); } catch (Exception ex) { Console.WriteLine(ex); // this outputs the information I would like throw; } Having this information will make the initial phase of testing and deployment a lot less painful. I know I can just wrap each unit test in a generic exception handler and write the exception to the console and rethrow (as above) within all my unit tests but that seems a very long-winded way of achieving this (and would look pretty awful). Does anyone know if there's any way to get this information included for free whenever an unhandled exception occurs? Is there a setting that I am missing? Is my service configuration lacking in proper fault handling? Perhaps I could write some kind of plug-in / adapter for some unit testing framework? Perhaps theres a different unit testing framework which I should be using instead! My actual set-up is xUnit unit tests executed via Gallio for the development environment, but I do have a separate suite of "smoke tests" written which I would like to be able to have our engineers run via the xUnit GUI test runner (or Gallio or whatever) to simplify the final deployment. Thanks. Adam

  • How to maxmise the largest contiguous block of memory in the Large Object Heap

    - by Unsliced
    The situation is that I am making a WCF call to a remote server which is returns an XML document as a string. Most of the time this return value is a few K, sometimes a few dozen K, very occasionally a few hundred K, but very rarely it could be several megabytes (first problem is that there is no way for me to know). It's these rare occasions that are causing grief. I get a stack trace that starts: System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. at System.Xml.BufferBuilder.AddBuffer() at System.Xml.BufferBuilder.AppendHelper(Char* pSource, Int32 count) at System.Xml.BufferBuilder.Append(Char[] value, Int32 start, Int32 count) at System.Xml.XmlTextReaderImpl.ParseText() at System.Xml.XmlTextReaderImpl.ParseElementContent() at System.Xml.XmlTextReaderImpl.Read() at System.Xml.XmlTextReader.Read() at System.Xml.XmlReader.ReadElementString() at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderMDRQuery.Read2_getMarketDataResponse() at Microsoft.Xml.Serialization.GeneratedAssembly.ArrayOfObjectSerializer2.Deserialize(XmlSerializationReader reader) at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events) at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle) at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) I've read around and it is because the Large Object Heap is just getting too fragmented, so even preceding the call with a quick check to StringBuilder.EnsureCapacity just causes the OutOfMemoryException to be thrown earlier (and because I'm guessing at what's needed, it might not actually need that much so my check is causing more problems than it is solving). Some opinions are that there's not much I can do about it. Some of the questions I've asked myself: Use less memory - have you checked for leaks? Yes. The memory usage goes up and down, but there's no fundamental growth that guarantees this to happen. Some of the times it fails, it succeeded at that stage previously. Transfer smaller amounts Not an option, this is a third party web service over which I have no control (or at least it would take a long time to resolve, in the meantime I still have a problem) Can you do something to the LOH to make it less likely to fail? ... now this is most fruitful course. It's a 32-bit process (it has to be for various political, technical and boring reasons) but there's normally hundreds of meg free (multiples of the largest amount for which we've seen failures). Can we monitor the LOH? Using perfmon I can track the size of the heaps, but I don't think there's a way to monitor the largest available contiguous block of memory. Question is: any advice or suggestions for things to try?

  • Using jQuery and OData to Insert a Database Record

    - by Stephen Walther
    In my previous blog entry, I explored two ways of inserting a database record using jQuery. We added a new Movie to the Movie database table by using a generic handler and by using a WCF service. In this blog entry, I want to take a brief look at how you can insert a database record using OData. Introduction to OData The Open Data Protocol (OData) was developed by Microsoft to be an open standard for communicating data across the Internet. Because the protocol is compatible with standards such as REST and JSON, the protocol is particularly well suited for Ajax. OData has undergone several name changes. It was previously referred to as Astoria and ADO.NET Data Services. OData is used by Sharepoint Server 2010, Azure Storage Services, Excel 2010, SQL Server 2008, and project code name “Dallas.” Because OData is being adopted as the public interface of so many important Microsoft technologies, it is a good protocol to learn. You can learn more about OData by visiting the following websites: http://www.odata.org http://msdn.microsoft.com/en-us/data/bb931106.aspx When using the .NET framework, you can easily expose database data through the OData protocol by creating a WCF Data Service. In this blog entry, I will create a WCF Data Service that exposes the Movie database table. Create the Database and Data Model The MoviesDB database is a simple database that contains the following Movies table: You need to create a data model to represent the MoviesDB database. In this blog entry, I use the ADO.NET Entity Framework to create my data model. However, WCF Data Services and OData are not tied to any particular OR/M framework such as the ADO.NET Entity Framework. For details on creating the Entity Framework data model for the MoviesDB database, see the previous blog entry. Create a WCF Data Service You create a new WCF Service by selecting the menu option Project, Add New Item and selecting the WCF Data Service item template (see Figure 1). Name the new WCF Data Service MovieService.svc. Figure 1 – Adding a WCF Data Service Listing 1 contains the default code that you get when you create a new WCF Data Service. There are two things that you need to modify. Listing 1 – New WCF Data Service File using System; using System.Collections.Generic; using System.Data.Services; using System.Data.Services.Common; using System.Linq; using System.ServiceModel.Web; using System.Web; namespace WebApplication1 { public class MovieService : DataService< /* TODO: put your data source class name here */ > { // This method is called only once to initialize service-wide policies. public static void InitializeService(DataServiceConfiguration config) { // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc. // Examples: // config.SetEntitySetAccessRule("MyEntityset", EntitySetRights.AllRead); // config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } } First, you need to replace the comment /* TODO: put your data source class name here */ with a class that represents the data that you want to expose from the service. In our case, we need to replace the comment with a reference to the MoviesDBEntities class generated by the Entity Framework. Next, you need to configure the security for the WCF Data Service. By default, you cannot query or modify the movie data. We need to update the Entity Set Access Rule to enable us to insert a new database record. The updated MovieService.svc is contained in Listing 2: Listing 2 – MovieService.svc using System.Data.Services; using System.Data.Services.Common; namespace WebApplication1 { public class MovieService : DataService<MoviesDBEntities> { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("Movies", EntitySetRights.AllWrite); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } } That’s all we have to do. We can now insert a new Movie into the Movies database table by posting a new Movie to the following URL: /MovieService.svc/Movies The request must be a POST request. The Movie must be represented as JSON. Using jQuery with OData The HTML page in Listing 3 illustrates how you can use jQuery to insert a new Movie into the Movies database table using the OData protocol. Listing 3 – Default.htm <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>jQuery OData Insert</title> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="Scripts/json2.js" type="text/javascript"></script> </head> <body> <form> <label>Title:</label> <input id="title" /> <br /> <label>Director:</label> <input id="director" /> </form> <button id="btnAdd">Add Movie</button> <script type="text/javascript"> $("#btnAdd").click(function () { // Convert the form into an object var data = { Title: $("#title").val(), Director: $("#director").val() }; // JSONify the data var data = JSON.stringify(data); // Post it $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "MovieService.svc/Movies", data: data, dataType: "json", success: insertCallback }); }); function insertCallback(result) { // unwrap result var newMovie = result["d"]; // Show primary key alert("Movie added with primary key " + newMovie.Id); } </script> </body> </html> jQuery does not include a JSON serializer. Therefore, we need to include the JSON2 library to serialize the new Movie that we wish to create. The Movie is serialized by calling the JSON.stringify() method: var data = JSON.stringify(data); You can download the JSON2 library from the following website: http://www.json.org/js.html The jQuery ajax() method is called to insert the new Movie. Notice that both the contentType and dataType are set to use JSON. The jQuery ajax() method is used to perform a POST operation against the URL MovieService.svc/Movies. Because the POST payload contains a JSON representation of a new Movie, a new Movie is added to the database table of Movies. When the POST completes successfully, the insertCallback() method is called. The new Movie is passed to this method. The method simply displays the primary key of the new Movie: Summary The OData protocol (and its enabling technology named WCF Data Services) works very nicely with Ajax. By creating a WCF Data Service, you can quickly expose your database data to an Ajax application by taking advantage of open standards such as REST, JSON, and OData. In the next blog entry, I want to take a closer look at how the OData protocol supports different methods of querying data.

  • maxItemsInObjectGraph ignored...

    - by Palantir
    Hi! I have a problem with a WCF service, which tries to serialize too much data. From the trace I get an error which says that the maximum number of elements that can be serialized or unserialized is '65536', try to increment the MaxItemsInObjectGraph quota. So I went and modified this value, but it is just ignored (the error is the same, with the same number). All this is server-side. I am calling the service via wget for the moment. My web config is like this: <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="AlgoMap.Web.MapService.MapServiceBehavior"> <dataContractSerializer maxItemsInObjectGraph="131072" /> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> </behaviors> <bindings> <customBinding> <binding name="customBinding0" closeTimeout="00:02:00" openTimeout="00:02:00" receiveTimeout="00:02:00"> <binaryMessageEncoding> <readerQuotas maxDepth="64" maxStringContentLength="16384" maxArrayLength="16384" maxBytesPerRead="16384" maxNameTableCharCount="16384" /> </binaryMessageEncoding> <httpTransport /> </binding> </customBinding> </bindings> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> <services> <service behaviorConfiguration="AlgoMap.Web.MapService.MapServiceBehavior" name="AlgoMap.Web.MapService.MapService"> <endpoint address="" binding="customBinding" bindingConfiguration="customBinding0" contract="AlgoMap.Web.MapService.MapService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> </system.serviceModel> Version 2, not working either: <system.serviceModel> <behaviors> <endpointBehaviors> <behavior name="AlgoMap.Web.MapService.MapServiceEndpointBehavior"> <dataContractSerializer maxItemsInObjectGraph="131072" /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="AlgoMap.Web.MapService.MapServiceBehavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> </behaviors> <bindings> <customBinding> <binding name="customBinding0" closeTimeout="00:02:00" openTimeout="00:02:00" receiveTimeout="00:02:00"> <binaryMessageEncoding> <readerQuotas maxDepth="64" maxStringContentLength="16384" maxArrayLength="16384" maxBytesPerRead="16384" maxNameTableCharCount="16384" /> </binaryMessageEncoding> <httpTransport /> </binding> </customBinding> </bindings> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> <services> <service behaviorConfiguration="AlgoMap.Web.MapService.MapServiceBehavior" name="AlgoMap.Web.MapService.MapService"> <endpoint address="" binding="customBinding" bindingConfiguration="customBinding0" contract="AlgoMap.Web.MapService.MapService" behaviorConfiguration="AlgoMap.Web.MapService.MapServiceEndpointBehavior" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" behaviorConfiguration="AlgoMap.Web.MapService.MapServiceEndpointBehavior" /> </service> </services> </system.serviceModel> Can anyone help??

  • Transport Security with Certificate Authentication

    - by Brian T
    I'm getting the following error when I access my webservice localhost/MyService/MyService.svc The SSL settings for the service 'SslRequireCert' does not match those of the IIS 'Ssl, SslNegotiateCert'.

  • Different Service behaviors per endpoint

    - by Preben Huybrechts
    The situation We are implementing different sort of security on some WCF service. ClientCertificate, UserName & Password and Anonymous. We have 2 ServiceBehaviorConfigurations, one for httpBinding and one for wsHttpBinding. (We have custom authorization policies for claim based security) As a requirement we need different endpoints for each service. 3 endpoints with httpBinding and 1 with wsHttpBinding. Example for one service: basicHttpBinding : Anonymous basicHttpBinding : UserNameAndPassword basicHttpBinding : BasicSsl wsHttpBinding : BasicSsl The Problem Part 1: We cannot specify the same service twice, once with the http service configuration and once with the wsHttp service configuration. Part 2: We cannot specify service behaviors on an endpoint. (Throws and exception, No endpoint behavior was found... Service behaviors cant be set to endpoint behaviours) The Config For part 1: <services> <service name="Namespace.MyService" behaviorConfiguration="securityBehavior"> <endpoint address="http://server:94/MyService.svc/Anonymous" contract="Namespace.IMyService" binding="basicHttpBinding" bindingConfiguration="Anonymous"> </endpoint> <endpoint address="http://server:94/MyService.svc/UserNameAndPassword" contract="Namespace.IMyService" binding="basicHttpBinding" bindingConfiguration="UserNameAndPassword"> </endpoint> <endpoint address="https://server/MyService.svc/BasicSsl" contract="Namespace.IMyService" binding="basicHttpBinding" bindingConfiguration="BasicSecured"> </endpoint> </service> <service name="Namespace.MyService" behaviorConfiguration="wsHttpCertificateBehavior"> <endpoint address="https://server/MyService.svc/ClientCert" contract="Namespace.IMyService" binding="wsHttpBinding" bindingConfiguration="ClientCert"/> </service> </services> Service Behavior configuration: <serviceBehaviors> <behavior name="securityBehavior"> <serviceAuthorization serviceAuthorizationManagerType="Namespace.AdamAuthorizationManager,Assembly"> <authorizationPolicies> <add policyType="Namespace.AdamAuthorizationManager,Assembly" /> </authorizationPolicies> </serviceAuthorization> </behavior> <behavior name="wsHttpCertificateBehavior"> <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/> <serviceAuthorization serviceAuthorizationManagerType="Namespace.AdamAuthorizationManager,Assembly"> <authorizationPolicies> <add policyType="Namespace.AdamAuthorizationManager,Assembly" /> </authorizationPolicies> </serviceAuthorization> <serviceCredentials> <clientCertificate> <authentication certificateValidationMode="PeerOrChainTrust" revocationMode="NoCheck"/> </clientCertificate> <serviceCertificate findValue="CN=CertSubject"/> </serviceCredentials> </behavior> How can we specify a different service behaviour on the WsHttpBinding endpoint? Or how can we apply our authorization policy in a different way for wsHttpBinding then basicHttpBinding. We would use endpoint behavior but we can't specify our authorization policy on an endpoint behavior

  • WebLogic Server Weekly for March 26th, 2012: WLS 1211 Update, Java 7 Certification, Galleria, WebLogic for DBAs, REST and Enterprise Architecture, Singleton Services

    - by Steve Button
    WebLogic Server 12c Certified with Java 7 for Production Use WebLogic Server 12c (12.1.1) has been certified with JDK 7 for development usage since December and we have now completed JDK 7 certification for use with production systems. In doing so, we have updated the WebLogic Server 12c (12.1.1) distributions incorporating fixes associated with JDK 7 support as well as some bundled patches that address several issues that have been discovered since the initial release. These updated distributions are available for download from OTN and will be beneficial for all WebLogic Server 12c (12.1.1) users in general. What's New Release Notes Download Here! Updated Oracle WebLogic Server 12.1.1.0 distribution Never one to miss a trick, Markus Eisele was one of the first to notice the WebLogic Server 12c update and post a blog about it. Sources told me that as of Friday last week you have an updated version of WebLogic Server 12c on OTN. http://blog.eisele.net/2012/03/updated-oracle-weblogic-server-12110.html Using WebLogic Server 12c with Java 7 - Video To illustrate the use of Java 7 with WebLogic Server 12c, I put together a screen cam showing the creation of a domain using Java 7 and then build and deploy a simple web application that uses Java 7 syntax to show it working. Ireland OUG Presentation: WebLogic for DBAs Simon Haslam posted his slides from a presentation he gave Dublin on 21/3/12 at the OUG Ireland conference. In this presentation, he explains the core concepts and ideas behind WebLogic Server, walks through an installation and offers some tips and common gotcha's to avoid. Simon also covers some aspects of installing and use Enterprise Manager 12c. Note: I usually install the JVM and use the generic .jar installer rather than using an installer bundled with a JVM. http://www.slideshare.net/Veriton/weblogic-for-dbas-10h Slightly Retro: Jeff West on Enterprise Architecure and REST In this weeks flashback, we look at Jeff West's blog from early 2011 where he provides some thoughtful opinions on enterprise architecture and innovation, then jumps into his views on REST. After I progressed in my career and did more team-leading and architecture type roles I was ‘educated’ on what it meant to have Asynchronous and Long-Running processes as part of your Enterprise Application architecture. If I had a synchronous process then I needed a thread available to service the request and then provide the response. https://blogs.oracle.com/jeffwest/entry/weblogic_integration_wli_web_services_and_soap_and_rest_part_1 Starting Managed Servers without an Administration Server using Node Manager and WLST Blogger weblogic-tips shows how to start a managed server without going through the Administration Server, using the Node Manager and WLST. Connect WLST to a Node Manager by entering the nmConnect command. http://www.weblogic-tips.com/2012/02/18/starting-managed-servers-without-an-administration-server-using-node-manager-and-wlst/ Using WebLogic Server Singleton Services WebLogic Server has supported the notion of a Singleton Service for a number of releases, in which WebLogic Server will maintain a single instance of a configured singleton service on one managed server within a cluster. This blog demonstrates how the singleton service can be accessed and used from applications deployed on the cluster. http://buttso.blogspot.com.au/2012/03/weblogic-server-singleton-services.html

  • DynamicObject and WCF support

    - by rboarman
    Hi, I was wondering if anyone has had any luck getting a DynamicObject to serialize and work with WCF? Here’s my little test: [DataContract] class MyDynamicObject : DynamicObject { [DataMember] private Dictionary<string, object> _attributes = new Dictionary<string, object>(); public override bool TryGetMember(GetMemberBinder binder, out object result) { string key = binder.Name; result = null; if (_attributes.ContainsKey(key)) result = _attributes[key]; return true; } public override bool TrySetMember(SetMemberBinder binder, object value) { _attributes.Add(binder.Name, value); return true; } } var dy = new MyDynamicObject(); var ser = new DataContractSerializer(typeof(MyDynamicObject)); var mem = new MemoryStream(); ser.WriteObject(mem, dy); The error I get is: System.Runtime.Serialization.InvalidDataContractException was unhandled Message=Type 'ElasticTest1.MyDynamicObject' cannot inherit from a type that is not marked with DataContractAttribute or SerializableAttribute. Consider marking the base type 'System.Dynamic.DynamicObject' with DataContractAttribute or SerializableAttribute, or removing them from the derived type. Any suggestions? Thanks, Rick

  • silverlight 3: long running wcf call triggers 401.1 (access denied)

    - by sympatric greg
    I have a wcf service consumed by a silverlight 3 control. The Silverlight client uses a basicHttpBindinging that is constructed at runtime from the control's initialization parameters like this: public static T GetServiceClient<T>(string serviceURL) { BasicHttpBinding binding = new BasicHttpBinding(Application.Current.Host.Source.Scheme.Equals("https", StringComparison.InvariantCultureIgnoreCase) ? BasicHttpSecurityMode.Transport : BasicHttpSecurityMode.None); binding.MaxReceivedMessageSize = int.MaxValue; binding.MaxBufferSize = int.MaxValue; binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly; return (T)Activator.CreateInstance(typeof(T), new object[] { binding, new EndpointAddress(serviceURL)}); } The Service implements windows security. Calls were returning as expected until the result set increased to several thousand rows at which time HTTP 401.1 errors were received. The Service's HttpBinding defines closeTime, openTimeout, receiveTimeout and sendTimeOut of 10 minutes. If I limit the size of the resultset the call suceeds. Additional Observations from Fiddler: When Method2 is modified to return a smaller resultset (and avoid the problem), control initialization consists of 4 calls: Service1/Method1 -- result:401 Service1/Method1 -- result:401 (this time header includes element "Authorization: Negotiate TlRMTV..." Service1/Method1 -- result:200 Service1/Method2 -- result:200 (1.25 seconds) When Method2 is configured to return the larger resultset we get: Service1/Method1 -- result:401 Service1/Method1 -- result:401 (this time header includes element "Authorization: Negotiate TlRMTV..." Service1/Method1 -- result:200 Service1/Method2 -- result:401.1 (7.5 seconds) Service1/Method2 -- result:401.1 (15ms) Service1/Method2 -- result:401.1 (7.5 seconds)

  • Monotouch threads, GC, WCF

    - by cvista
    Hi This is a question about best practices i guess but it applies directly to my current MT project. I'm using WCF services to communicate with the server. To do this i do the following: services.MethodToCall(params); and the asynch: services.OnMethodToCallCompleted += delegate{ //do stuff and ting }; This can lead to issues if you're not careful in that variables defined within the scope of the asynch callback can sometimes be cleaned up by the gc and this can cause crashes. So - I am making it a practice to declare these outside of the scope of the callback unless I am 100% sure they are not needed. Now - when doing stuff and ting implies changing the ui - i wrap it all in an InvokeOnMainThread call. I guess wrapping everything in this would slow the main thread down and rubbish the point of having multi threads. Even though I'm being careful about all this i am still getting crashes and I have no idea why! I am certain it has something to do with threads, scope and all that. Now - the only thing I can think of outside of updating the UI that may need to happen inside of InvokeOnMainThread is that I have a singleton 'Database' class. This is based on the version 5 code from this thread http://www.yoda.arachsys.com/csharp/singleton.html So now if the service method returns data that needs to be added/updated to the Database class -I also wrap this inside an InvokeOnMainThread call. Still getting random crashes. So... My question is this: I am new to thick client dev - I'm coming from a web dev perspective where we don't need to worry about threads so much :) Aside from what I have mentioned -are there any other things I should be aware of? Is the above stuff correct? Or am i miss-understanding something? Cheers w://

  • Consuming a WCF Service

    - by Lijo
    Hi I created a WCF service which is hosted in windows service. I created a proxy using svcutil “svcutil.exe http://localhost:8000/ServiceModelSamples/FreeServiceWorld?wsdl” It generated an output.config file and proxy class. The output.config has the following element <client> <endpoint address="http://localhost:8000/ServiceModelSamples/FreeServiceWorld" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IWeather" contract="IWeather" name="WSHttpBinding_IWeather"> <identity> <servicePrincipalName value="host/D471DTRV.ustr.com" /> </identity> </endpoint> </client> I created a website (as client) and added a new C# file (MyFile.cs) into it. I copied the contents of the proxy class into MyFile.cs. [The output.config is not copied to the web site] In the code behnid of aspx, I am using the following code WeatherClient client= new WeatherClient("WSHttpBinding_IWeather"); It throws an exception as “Could not find endpoint element with name 'WSHttpBinding_IWeather' and contract 'IWeather' in the ServiceModel client configuration section.” Could you please help me to understand the missing link here? Thanks Lijo

  • Creating a consumer of a Web Service WSDL/SOAP

    - by Azzi
    I am attempting to write a Windows Desktop App (using WCF) that is a consumer of a web service. The application: Sends a SOAP message to a British Government Server to get an authentication token based on the arugments passed Retrieves a response from that server in the form of a string which contains the authentication token. I have a template of the SOAP message from the British Government, and a WSDL file for the service. What I have tried Add a service reference using the WSDL file. I received the following error: URI formats are not supported. Add a Web Reference using the URL of the service. I received the following error: The request failed with HTTP status 405: Method Not Allowed. Send the SOAP request using a POST. The Call to GetResponse() threw a 500 External Server Error.
