  • Are WCF Services encrypted automatically if they go over SSL?

    - by michael
    Basically, if I have a plain WCF Service over HTTPS is it automatically secure? [ServiceContract] public interface ICalc { [OperationContract] int add(int a, int b); } public class Calculator : ICalc { public int add(int a, int b) { return a + b; } } I figure the actual SOAP message isn't encrypted here, but is it still secure if I use https? Basically, if I use a basichttpbinding with no security settings in my config over https://www.myserver.com/services/Calc.svc is that secure?

  • What to filter when providing very limited open WiFi to a small conference or meeting?

    - by Tim Farley
    Executive Summary The basic question is: if you have a very limited bandwidth WiFi to provide Internet for a small meeting of only a day or two, how do you set the filters on the router to avoid one or two users monopolizing all the available bandwidth? For folks who don't have the time to read the details below, I am NOT looking for any of these answers: Secure the router and only let a few trusted people use it Tell everyone to turn off unused services & generally police themselves Monitor the traffic with a sniffer and add filters as needed I am aware of all of that. None are appropriate for reasons that will become clear. ALSO NOTE: There is already a question concerning providing adequate WiFi at large (500 attendees) conferences here. This question concerns SMALL meetings of less than 200 people, typically with less than half that using the WiFi. Something that can be handled with a single home or small office router. Background I've used a 3G/4G router device to provide WiFi to small meetings in the past with some success. By small I mean single-room conferences or meetings on the order of a barcamp or Skepticamp or user group meeting. These meetings sometimes have technical attendees there, but not exclusively. Usually less than half to a third of the attendees will actually use the WiFi. Maximum meeting size I'm talking about is 100 to 200 people. I typically use a Cradlepoint MBR-1000 but many other devices exist, especially all-in-one units supplied by 3G and/or 4G vendors like Verizon, Sprint and Clear. These devices take a 3G or 4G internet connection and fan it out to multiple users using WiFi. One key aspect of providing net access this way is the limited bandwidth available over 3G/4G. Even with something like the Cradlepoint which can load-balance multiple radios, you are only going to achieve a few megabits of download speed and maybe a megabit or so of upload speed. That's a best case scenario. Often it is considerably slower. The goal in most of these meeting situations is to allow folks access to services like email, web, social media, chat services and so on. This is so they can live-blog or live-tweet the proceedings, or simply chat online or otherwise stay in touch (with both attendees and non-attendees) while the meeting proceeds. I would like to limit the services provided by the router to just those services that meet those needs. Problems In particular I have noticed a couple of scenarios where particular users end up abusing most of the bandwidth on the router, to the detriment of everyone. These boil into two areas: Intentional use. Folks looking at YouTube videos, downloading podcasts to their iPod, and otherwise using the bandwidth for things that really aren't appropriate in a meeting room where you should be paying attention to the speaker and/or interacting.At one meeting that we were live-streaming (over a separate, dedicated connection) via UStream, I noticed several folks in the room that had the UStream page up so they could interact with the meeting chat - apparently oblivious that they were wasting bandwidth streaming back video of something that was taking place right in front of them. Unintentional use. There are a variety of software utilities that will make extensive use of bandwidth in the background, that folks often have installed on their laptops and smartphones, perhaps without realizing.Examples: Peer to peer downloading programs such as Bittorrent that run in the background Automatic software update services. These are legion, as every major software vendor has their own, so one can easily have Microsoft, Apple, Mozilla, Adobe, Google and others all trying to download updates in the background. Security software that downloads new signatures such as anti-virus, anti-malware, etc. Backup software and other software that "syncs" in the background to cloud services. For some numbers on how much network bandwidth gets sucked up by these non-web, non-email type services, check out this recent Wired article. Apparently web, email and chat all together are less than one quarter of the Internet traffic now. If the numbers in that article are correct, by filtering out all the other stuff I should be able to increase the usefulness of the WiFi four-fold. Now, in some situations I've been able to control access using security on the router to limit it to a very small group of people (typically the organizers of the meeting). But that's not always appropriate. At an upcoming meeting I would like to run the WiFi without security and let anyone use it, because it happens at the meeting location the 4G coverage in my town is particularly excellent. In a recent test I got 10 Megabits down at the meeting site. The "tell people to police themselves" solution mentioned at top is not appropriate because of (a) a largely non-technical audience and (b) the unintentional nature of much of the usage as described above. The "run a sniffer and filter as needed" solution is not useful because these meetings typically only last a couple of days, often only one day, and have a very small volunteer staff. I don't have a person to dedicate to network monitoring, and by the time we got the rules tweaked completely the meeting will be over. What I've Got First thing, I figured I would use OpenDNS's domain filtering rules to filter out whole classes of sites. A number of video and peer-to-peer sites can be wiped out using this. (Yes, I am aware that filtering via DNS technically leaves the services accessible - remember, these are largely non-technical users attending a 2 day meeting. It's enough). I figured I would start with these selections in OpenDNS's UI: I figure I will probably also block DNS (port 53) to anything other than the router itself, so that folks can't bypass my DNS configuration. A savvy user could get around this, because I'm not going to put a lot of elaborate filters on the firewall, but I don't care too much. Because these meetings don't last very long, its probably not going to be worth the trouble. This should cover the bulk of the non-web traffic, i.e. peer-to-peer and video if that Wired article is correct. Please advise if you think there are severe limitations to the OpenDNS approach. What I Need Note that OpenDNS focuses on things that are "objectionable" in some context or another. Video, music, radio and peer-to-peer all get covered. I still need to cover a number of perfectly reasonable things that we just want to block because they aren't needed in a meeting. Most of these are utilities that upload or download legit things in the background. Specifically, I'd like to know port numbers or DNS names to filter in order to effectively disable the following services: Microsoft automatic updates Apple automatic updates Adobe automatic updates Google automatic updates Other major software update services Major virus/malware/security signature updates Major background backup services Other services that run in the background and can eat lots of bandwidth I also would like any other suggestions you might have that would be applicable. Sorry to be so verbose, but I find it helps to be very, very clear on questions of this nature, and I already have half a solution with the OpenDNS thing.

  • iPhone / Android: what protocol stacks do apps use for connecting to centralised services?

    - by Richard
    Hi All, Aplogies for the ignorant question, I have no experience with app development on any mobile platform. Basically what I want to know is what communication protocols do apps typically use for accessing/querying centralised services? E.g if I port a webapp/service to iPhone/Andriod, typically how would I access/query this web service in my app? E.g is it over HTTP, or are there other protocols? Also, presumably the GUI of an app is constructed with Apple/Andriod GUI libraries (in java? cocoa?). Can an app GUI be defined with HTML/javascript like a webpage? Sorry again for the pure noob questions. Thanks

  • Why is there no service-oriented language?

    - by Wolfgang
    Edit: To avoid further confusion: I am not talking about web services and such. I am talking about structuring applications internally, it's not about how computers communicate. It's about programming languages, compilers and how the imperative programming paradigm is extended. Original: In the imperative programming field, we saw two paradigms in the past 20 years (or more): object-oriented (OO), and service-oriented (SO) aka. component-based (CB). Both paradigms extend the imperative programming paradigm by introducing their own notion of modules. OO calls them objects (and classes) and lets them encapsulates both data (fields) and procedures (methods) together. SO, in contrast, separates data (records, beans, ...) from code (components, services). However, only OO has programming languages which natively support its paradigm: Smalltalk, C++, Java and all other JVM-compatibles, C# and all other .NET-compatibles, Python etc. SO has no such native language. It only comes into existence on top of procedural languages or OO languages: COM/DCOM (binary, C, C++), CORBA, EJB, Spring, Guice (all Java), ... These SO frameworks clearly suffer from the missing native language support of their concepts. They start using OO classes to represent services and records. This leads to designs where there is a clear distinction between classes that have methods only (services) and those that have fields only (records). Inheritance between services or records is then simulated by inheritance of classes. Technically, its not kept so strictly but in general programmers are adviced to make classes to play only one of the two roles. They use additional, external languages to represent the missing parts: IDL's, XML configurations, Annotations in Java code, or even embedded DSL like in Guice. This is especially needed, but not limited to, since the composition of services is not part of the service code itself. In OO, objects create other objects so there is no need for such facilities but for SO there is because services don't instantiate or configure other services. They establish an inner-platform effect on top of OO (early EJB, CORBA) where the programmer has to write all the code that is needed to "drive" SO. Classes represent only a part of the nature of a service and lots of classes have to be written to form a service together. All that boiler plate is necessary because there is no SO compiler which would do it for the programmer. This is just like some people did it in C for OO when there was no C++. You just pass the record which holds the data of the object as a first parameter to the procedure which is the method. In a OO language this parameter is implicit and the compiler produces all the code that we need for virtual functions etc. For SO, this is clearly missing. Especially the newer frameworks extensively use AOP or introspection to add the missing parts to a OO language. This doesn't bring the necessary language expressiveness but avoids the boiler platform code described in the previous point. Some frameworks use code generation to produce the boiler plate code. Configuration files in XML or annotations in OO code is the source of information for this. Not all of the phenomena that I mentioned above can be attributed to SO but I hope it clearly shows that there is a need for a SO language. Since this paradigm is so popular: why isn't there one? Or maybe there are some academic ones but at least the industry doesn't use one.

  • My .NET Technology picks for 2011

    - by shiju
    My Technology predictions for 2011 Cloud computing and Mobile application development will be the hottest trends for 2011. I hope that Windows Azure will be very hot in year 2011 and lot of cloud computing adoption will be happen with Windows Azure on 2011. Web application scalability will be the big challenge for Architects in the next year and architecture approaches like CQRS will get some attention on next year. Architects will look on different options for web application scalability and adoption of NoSQL and Document databases will be more in the year 2011. The following are the my technology picks for .Net stack Windows Azure Windows Azure will be one of the hottest technologies of 2011. Adoption of Cloud and Windows Azure will get big attention on next year. The Windows Azure platform is a flexible cloud–computing platform that lets you focus on solving business problems and addressing customer needs. No need to invest upfront on expensive infrastructure. Pay only for what you use, scale up when you need capacity and pull it back when you don’t. We handle all the patches and maintenance — all in a secure environment with over 99.9% uptime. Silverlight 5 Silverlight is becoming a common technology for variety of development platforms. You can develop Silverlight applications for web, desktop and windows phone. The new Silverlight 5 beta will be available during the starting quarter of the next year with new capabilities and lot of new features. Silverlight 5 will be powerful development platform for both web-based business apps and rich media solutions. We can expect final version of Silverlight 5 on end of 2011. Windows Phone 7 Development Tools Mobile application development will be very hot in year 2011 and Windows Phone 7 will be one of the hottest technologies of next year. You can get introduction on Windows Phone 7 Development Tools from somasegar’s blog post and MSDN documentation available from here. EF Code First I am a big fan of Entity Framework’s Code First approach and hope that Code First approach will attract more people onto Entity Framework 4. EF Code First lets you focus on domain model which will enable Domain-Driven Development for applications. I hope that DDD fans will love the EF Code First approach. The Entity Framework 4 now supports three types of approaches and these will attract different types of developer audience. ASP.NET MVC 3 The ASP.NET MVC 3 will be the hottest technology of Microsoft web stack on the next year. ASP.NET developers will widely move to the ASP.NET MVC Framework from their WebForms development. The new Razor view engine is great and it will increase the adoption of ASP.NET MVC 3. Razor the will improve the productivity when working with ASP.NET MVC 3 Views. You can build great web applications using ASP.NET MVC 3 and jQuery with better maintainability, generation of clean HTML and even better performance. In my opinion, the best technology stack for web development is ASP.NET MVC 3 and Entity Framework 4 Code First as ORM. On the next year, you can expect more articles from my blog on ASP.NET MVC 3 and Entity Framework 4 Code First. RavenDB NoSQL and Document databases will get more attention on the coming year and RavenDB will be the most notable document database in the .NET stack. RavenDB is an Open Source (with a commercial option) document database for the .NET/Windows platform developed by Ayende Rahien. RavenDB is .NET focused document database which comes with a fully functional .NET client API and supports LINQ. I have written few articles on RavenDB and you can read it from here. Managed Extensibility Framework (MEF) Many people didn't realized the power of MEF. The MEF lets you create extensible applications and provides a great solution for the runtime extensibility problem. I hope that .NET developers will more adopt the MEF on the next year for their .NET applications. You can get an excellent introduction on MEF from Anoop Madhusudanan’s blog post MEF or Managed Extensibility Framework – Creating a Zoo and Animals

  • Thinking Local, Regional and Global

    - by Apeksha Singh-Oracle
    The FIFA World Cup tournament is the biggest single-sport competition: it’s watched by about 1 billion people around the world. Every four years each national team’s manager is challenged to pull together a group players who ply their trade across the globe. For example, of the 23 members of Brazil’s national team, only four actually play for Brazilian teams, and the rest play in England, France, Germany, Spain, Italy and Ukraine. Each country’s national league, each team and each coach has a unique style. Getting all these “localized” players to work together successfully as one unit is no easy feat. In addition to $35 million in prize money, much is at stake – not least national pride and global bragging rights until the next World Cup in four years time. Achieving economic integration in the ASEAN region by 2015 is a bit like trying to create the next World Cup champion by 2018. The team comprises Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, Philippines, Singapore, Thailand and Vietnam. All have different languages, currencies, cultures and customs, rules and regulations. But if they can pull together as one unit, the opportunity is not only great for business and the economy, but it’s also a source of regional pride. BCG expects by 2020 the number of firms headquartered in Asia with revenue exceeding $1 billion will double to more than 5,000. Their trade in the region and with the world is forecast to increase to 37% of an estimated $37 trillion of global commerce by 2020 from 30% in 2010. Banks offering transactional banking services to the emerging market place need to prepare to repond to customer needs across the spectrum – MSMEs, SMEs, corporates and multi national corporations. Customers want innovative, differentiated, value added products and services that provide: • Pan regional operational independence while enabling single source of truth at a regional level • Regional connectivity and Cash & Liquidity  optimization • Enabling Consistent experience for their customers  by offering standardized products & services across all ASEAN countries • Multi-channel & self service capabilities / access to real-time information on liquidity and cash flows • Convergence of cash management with supply chain and trade finance While enabling the above to meet customer demands, the need for a comprehensive and robust credit management solution for effective regional banking operations is a must to manage risk. According to BCG, Asia-Pacific wholesale transaction-banking revenues are expected to triple to $139 billion by 2022 from $46 billion in 2012. To take advantage of the trend, banks will have to manage and maximize their own growth opportunities, compete on a broader scale, manage the complexity within the region and increase efficiency. They’ll also have to choose the right operating model and regional IT platform to offer: • Account Services • Cash & Liquidity Management • Trade Services & Supply Chain Financing • Payments • Securities services • Credit and Lending • Treasury services The core platform should be able to balance global needs and local nuances. Certain functions need to be performed at a regional level, while others need to be performed on a country level. Financial reporting and regulatory compliance are a case in point. The ASEAN Economic Community is in the final lap of its preparations for the ultimate challenge: becoming a formidable team in the global league. Meanwhile, transaction banks are designing their own hat trick: implementing a world-class IT platform, positioning themselves to repond to customer needs and establishing a foundation for revenue generation for years to come.

  • Why does Keychain Services return the wrong keychain content?

    - by Graham Lee
    I've been trying to use persistent keychain references in an iPhone application. I found that if I created two different keychain items, I would get a different persistent reference each time (they look like 'genp.......1', 'genp.......2', …). However, attempts to look up the items by persistent reference always returned the content of the first item. Why should this be? I confirmed that my keychain-saving code was definitely creating new items in each case (rather than updating existing items), and was not getting any errors. And as I say, Keychain Services is giving a different persistent reference for each item. I've managed to solve my immediate problem by searching for keychain items by attribute rather than persistent references, but it would be easier to use persistent references so I'd appreciate solving this problem. Here's my code: - (NSString *)keychainItemWithName: (NSString *)name { NSString *path = [GLApplicationSupportFolder() stringByAppendingPathComponent: name]; NSData *persistentRef = [NSData dataWithContentsOfFile: path]; if (!persistentRef) { NSLog(@"no persistent reference for name: %@", name); return nil; } NSArray *refs = [NSArray arrayWithObject: persistentRef]; //get the data CFMutableDictionaryRef params = CFDictionaryCreateMutable(NULL, 0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks); CFDictionaryAddValue(params, kSecMatchItemList, refs); CFDictionaryAddValue(params, kSecClass, kSecClassGenericPassword); CFDictionaryAddValue(params, kSecReturnData, kCFBooleanTrue); CFDataRef item = NULL; OSStatus result = SecItemCopyMatching(params, (CFTypeRef *)&item); CFRelease(params); if (result != errSecSuccess) { NSLog(@"error %d retrieving keychain reference for name: %@", result, name); return nil; } NSString *token = [[NSString alloc] initWithData: (NSData *)item encoding: NSUTF8StringEncoding]; CFRelease(item); return [token autorelease]; } - (void)setKeychainItem: (NSString *)newToken forName: (NSString *)name { NSData *tokenData = [newToken dataUsingEncoding: NSUTF8StringEncoding]; //firstly, find out whether the item already exists NSDictionary *searchAttributes = [NSDictionary dictionaryWithObjectsAndKeys: name, kSecAttrAccount, kCFBooleanTrue, kSecReturnAttributes, nil]; NSDictionary *foundAttrs = nil; OSStatus searchResult = SecItemCopyMatching((CFDictionaryRef)searchAttributes, (CFTypeRef *)&foundAttrs); if (noErr == searchResult) { NSMutableDictionary *toStore = [foundAttrs mutableCopy]; [toStore setObject: tokenData forKey: (id)kSecValueData]; OSStatus result = SecItemUpdate((CFDictionaryRef)foundAttrs, (CFDictionaryRef)toStore); if (result != errSecSuccess) { NSLog(@"error %d updating keychain", result); } [toStore release]; return; } //need to create the item. CFMutableDictionaryRef params = CFDictionaryCreateMutable(NULL, 0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks); CFDictionaryAddValue(params, kSecClass, kSecClassGenericPassword); CFDictionaryAddValue(params, kSecAttrAccount, name); CFDictionaryAddValue(params, kSecReturnPersistentRef, kCFBooleanTrue); CFDictionaryAddValue(params, kSecValueData, tokenData); NSData *persistentRef = nil; OSStatus result = SecItemAdd(params, (CFTypeRef *)&persistentRef); CFRelease(params); if (result != errSecSuccess) { NSLog(@"error %d from keychain services", result); return; } NSString *path = [GLApplicationSupportFolder() stringByAppendingPathComponent: name]; [persistentRef writeToFile: path atomically: NO]; [persistentRef release]; }

By optimizing clinical workflows for the most common diseases, Siemens also makes healthcare faster, better and more cost-effective. To ensure greater transparency, increased efficiency, higher user acceptance, and additional services, Siemens AG, Sector Healthcare, replaced several existing legacy portal solutions that could not meet the company’s future needs with Oracle WebCenter Portal. Various existing portal solutions that cannot meet future demands will be successively replaced by the new central service portal, which will also allow for the efficient and intuitive implementation of new service concepts.  With Oracle, doctors and hospitals using Siemens medical solutions now have access to a central information portal that provides important information and services at just the push of a button.  Customer Name – Siemens AG, Sector Healthcare Customer URL – www.siemens.com Customer Headquarters – Erlangen, Germany Industry – Industrial Manufacturing Employees – 360,000  Challenges – Replace disparate medical service portals to meet future demands and eliminate an  unnecessarily high level of administrative work caused by heterogeneous installations Ensure portals meet current user demands to improve user-acceptance rates and increase number of total users Enable changes and expansion through standard functionality to eliminate the need for reliance on IT and reduce administrative efforts and associated high costs Ensure efficient and intuitive implementation of new service concepts for all devices and systems Ensure hospitals and clinics to transparently monitor and measure services rendered for the various medical devices and systems  Increase electronic interaction and expand services to achieve a higher level of customer loyalty Solution –  Deployed Oracle WebCenter Portal to ensure greater transparency, and as a result, a higher level of customer loyalty  Provided a centralized platform for doctors and hospitals using Siemens’ medical technology solutions that provides important information and services at the push of a button Reduced significantly the administrative workload by centralizing the solution in the new customer service portal Secured positive feedback from customers involved in the pilot program developed by design experts from Oracle partner Sapient. The interfaces were created with customer needs in mind. The first survey taken shortly after implementation came back with 2.4 points on a scale of 0-3 in the category “customer service portal intuitiveness level” Met all requirements including alignment with the Siemens Style Guide without extensive programming Implemented additional services via the portal such as benchmarking options to ensure the optimal use of the Customer Device Park Provided option for documentation of all services rendered in conjunction with the medical technology systems to ensure that the value of the services are transparent for the decision makers in the hospitals  Saved and stored all machine data from approximately 100,000 remote systems in the central service and information platform Provided the option to register errors online and follow the call status in real-time on the portal Made  available at the push of a button all information on the medical technology devices used in hospitals or clinics—from security checks and maintenance activities to current device statuses Provided PDF format Service Performance Reports that summarize information from periods of time ranging from previous weeks up to one year, meeting medical product law requirements  Why Oracle – Siemens AG favored Oracle for many reasons, however, the company ultimately decided to go with Oracle due to the enormous range of functionality the solutions offered for the healthcare sector.“We are not programmers; we are service providers in the medical technology segment and focus on the contents of the portal. All the functionality necessary for internet-based customer interaction is already standard in Oracle WebCenter Portal, which is a huge plus for us. Having Oracle as our technology partner ensures that the product will continually evolve, providing a strong technology platform for our customer service portal well into the future,” said Joerg Modlmayr project manager, Healthcare Customer Service Portal, Siemens AG. Partner Involvement – Siemens AG selected Oracle Partner Sapient because the company offered a service portfolio that perfectly met Siemens’ requirements and had a wealth of experience implementing Oracle WebCenter Portal. Additionally, Sapient had designers with a very high level of expertise in usability—an aspect that Siemens considered to be of vast importance for the project.  “The Sapient team completely met all our expectations. Our tightly timed project was completed on schedule, and the positive feedback from our users proves that we set the right measures in terms of usability—all thanks to the folks at Sapient,” Modlmayr said.  Partner Name – Sapient GmbH Deutschland Partner URL – www.sapient.com

  • Windows Server (SBS) 2008 - Telephony service won't start (missing permissions)

    - by Uri
    I am running a SBS 2008 server. It's setup as the domain controller for the network. After a reboot, the Telephony service (and all services that depend on it) refuses to start under the Network Service account. The error given is: Error 1297: A privilege that the service requires to function properly does not exist in the service account configuration. You may use the Services Microsoft Management Console (MMC) snap-in (services.msc) and the Local Security Settings MMC snap-in (secpol.msc) to view the service configuration and the account configuration. This has caused all the network services not to be accessible e.g. terminal services, VPN (RRAS), SQL Server instances. The SSH daemon I have running on the box will accept connections only from localhost, but won't respond on the network. After searching around, the only advice I could find was to grant the Network Service account these permissions: Adjust memory quotas for a process Replace a process level token I set those permissions on both the Default Domain Policy and the Default Domain Controller Policy, but it seemingly had no effect. Most of the services will start if I change them to run under the Local System account, but that didn't make them accessible on the network. I even tried removing the Routing and Remote Access Services feature, rebooting and reinstalling it, but the issue remains. Any ideas?

  • Setting up HTTPS across multiple servers

    - by JohnyD
    I'm looking to offer our online services over https and I'm having a couple of problems understanding how to accomplish this. To access our services you must pass through our ISA firewall to a Win2000 server running IIS6. About half our services are located here and the other half take you to a Win2003 server also running IIS6. So, in order to achieve this must each server have the proper certificate installed? ISA, IIS6_1 and IIS6_2? Is there a separate configuration that must be made to our ISA firewall? The other problem is with the CA and knowing how many certificates I need. It's important to note that the domain name for our services on IIS6_1 is www.domainname.com but the domain name on IIS6_2 is services.domainname.com. I believe that this will require me to purchase more than one certificate. It looks as though we will be going with Thawte's SSL123 as it's a good name and it's fast to get. Will I need to purchase 2 certificates (one for www that will be installed on our ISA firewall as well as IIS6_1, and one for services.domainname.com on IIS6_2)? Or will I need to purchase 3, the extra one being used on our firewall server? Another side question is about SAN's (subject alternative names). Is this basically adding sub-domains to your cert? So I could purchase one cert with 1 SAN for my www and services.? Thanks a lot for your help! Please let me know if I can provide any further information.

  • JSON and jQuery.ajax

    - by Andreas
    Hello, im trying to use the jQuery UI autocomplete to communitate with a webservice with responseformate JSON, but i am unable to do so. My webservice is not even executed, the path should be correct since the error message does not complain about this. What strikes me is the headers, response is soap but request is json, is it supposed to be like this? Response Headersvisa källkod Content-Type application/soap+xml; charset=utf-8 Request Headersvisa källkod Accept application/json, text/javascript, */* Content-Type application/json; charset=utf-8 The error message i get is as follows (sorry for the huge message, but it might be of importance): soap:ReceiverSystem.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Xml.XmlException: Data at the root level is invalid. Line 1, position 1. at System.Xml.XmlTextReaderImpl.Throw(Exception e) at System.Xml.XmlTextReaderImpl.Throw(String res, String arg) at System.Xml.XmlTextReaderImpl.ParseRootLevelWhitespace() at System.Xml.XmlTextReaderImpl.ParseDocumentContent() at System.Xml.XmlTextReaderImpl.Read() at System.Xml.XmlTextReader.Read() at System.Web.Services.Protocols.SoapServerProtocol.SoapEnvelopeReader.Read() at System.Xml.XmlReader.MoveToContent() at System.Web.Services.Protocols.SoapServerProtocol.SoapEnvelopeReader.MoveToContent() at System.Web.Services.Protocols.SoapServerProtocolHelper.GetRequestElement() at System.Web.Services.Protocols.Soap12ServerProtocolHelper.RouteRequest() at System.Web.Services.Protocols.SoapServerProtocol.RouteRequest(SoapServerMessage message) at System.Web.Services.Protocols.SoapServerProtocol.Initialize() at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing) --- End of inner exception stack trace --- This is my code: $('selector').autocomplete({ source: function(request, response) { $.ajax({ url: "../WebService/Member.asmx", dataType: "json", contentType: "application/json; charset=utf-8", type: "POST", data: JSON.stringify({prefixText: request.term}), success: function(data) { alert('success'); }, error: function(XMLHttpRequest, textStatus, errorThrown){ alert('error'); } }) }, minLength: 1, select: function(event, ui) { } }); And my webservice looks like this: [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] [ScriptService] public class Member : WebService { [WebMethod(EnableSession = true)] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public string[] GetMembers(string prefixText) { code code code } } What am i doing wrong?

  • singleton pattern in Windows Activation Service

    - by Joshua
    Hello I have a few WCF services that are currently being self hosted, in a very basic NT Service. I want to expand my application to add provisioning of WCF Services, and updates, as well as isolation (I want each WCF Service to be in its own AppDomain). These WCF Services contain logic that needs to be run on a regular basis, pinging the database, and getting information from external devices so that when a request comes in the data is readily available. I'm thinking about trying out Windows Activation Service, because i really like the provisioning, and isolation that comes with a managed services infrastructure. If I didn't use WAS I would essentially have to write the same code myself. From what I understand though WAS does not really support the model of having a service that is running before someone actually calls a method on the service. the article I read here MSDN Article Link states "That means in essence that out-of-the-box WAS hosting is not something that is really suited for sessionful or singleton services. It is more suitable for stateless per-call services." it does say that "Out of the box" so I'm wondering if anyone has used WAS to host a WCF service that really behaves more like an NT Service (starting and stopping independantly of having a method called upon it). Or any other ideas would be great. I was planning on writting this infrastructure myself, to host WCF services in a custom ServiceHost, and put their execution in a seporate AppDomain, as well as allow for provision of these services after initial installation, along with updates. However, I would MUCH MUCH MUCH rather not own that code if I don't have to. thanks Joshua

  • Call WCF Service Through Javascript, AJAX, or JQuery

    - by obautista
    I created a number of standard WCF Services (Service Contract and Host (svc) are in separate assemblies). I fired up a Web Site in IIS to host the Services (i.e., address is http://services:1000/wcfservices.svc). Then in my Web Site project I added the reference. I am able to call the services normally. I am needed to call some of the services client side. Not sure if I should be looking at articles calling WCF services through AJAX, JQuery, or JSON enabled WCF Services. Can anyone provide any thoughts or experience with configuring as such? Some of the changes I made was adding the following to the Operation Contract: [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "SetFoo")] void SetFoo(string Id); Then this above the implementation of the interface: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] Then in the service webconfig I have this (parens are angle brackets): <serviceHostingEnvironment aspNetCompatibilityEnabled="true"> <baseAddressPrefixFilters> <add prefix="http://services:1000/wcfservices.svc/"/>> </baseAddressPrefixFilters> </serviceHostingEnvironment> <serviceHostingEnvironment multipleSiteBindingsEnabled="false" /> Then in the client side I attempted this: <asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server"> <compositeScript> <Scripts> <asp:ScriptReference Path="http://Flixsit:1000/FlixsitWebServices.svc" /> </Scripts> </CompositeScript> </asp:ScriptManagerProxy> I am attempting to call the service like this in javascript: wcfservices.SetFoo(string Id); Nothing is working. If it is idea or a better solution to call JSON enable, JQuery, etc....I am willing to make any changes. Thanks for any suggestions/tips provided....

  • Constructor on type: "Namespace.type" not found.

    - by Nick
    Hello, I am using Castle.Windsor as an IOC. So I am trying to resolve a service type in the constructor of an HTTPHandler. I keep receiving this error, "Constructor on type: "Namespace.type" not found." My configuration has the following entries for service type: IDocumentDirectory <component id="restricted.content.directory" service="org.healthwise.foundations.services.content.IDocumentDirectory, org.healthwise.foundations.services" type="org.healthwise.foundations.services.content.RestrictedLocalizationDocumentDirectory, org.healthwise.foundations.services"> <parameters> <contentDirectory>${content.directory}</contentDirectory> <localizations> <array> <item>en-us</item> <item>es-us</item> </array> </localizations> </parameters> </component> <component id="content.directory" service="org.healthwise.foundations.services.content.IDocumentDirectory, org.healthwise.foundations.services" type="org.healthwise.foundations.services.web.client.WebServiceDocumentDirectory, org.healthwise.foundations.services.web.client"> <parameters> <webServiceURL>#{contentDirectoryWebsiteUrl}</webServiceURL> </parameters> </component> In my new handler the constructor looks like this: public HeartBeatHttpHandler(IDocumentDirectory contentDirectory) { _contentDirectory = contentDirectory; } I have never recieved this error using Castle.Windsor. Can someone explain? Thanks!

  • Active Directory Services: PrincipalContext -- What is the DN of a "container" object?

    - by Ranger Pretzel
    I'm currently trying to authenticate via Active Directory Services using the PrincipalContext class. I would like to have my application authenticate to the Domain using Sealed and SSL contexts. In order to do this, I have to use the following constructor of PrincipalContext (link to MSDN page): public PrincipalContext( ContextType contextType, string name, string container, ContextOptions options ) Specifically, I'm using the constructor as so: PrincipalContext domainContext = new PrincipalContext( ContextType.Domain, domain, container, ContextOptions.Sealing | ContextOptions.SecureSocketLayer); MSDN says about "container": The container on the store to use as the root of the context. All queries are performed under this root, and all inserts are performed into this container. For Domain and ApplicationDirectory context types, this parameter is the distinguished name (DN) of a container object. What is the DN of a container object? How do I find out what my container object is? Can I query the Active Directory (or LDAP) server for this?
