• Random "Not Found" error with Silverlight accessing ASP.NET Web Services

  - by user245822

  I'm developing an application with Silverlight 3 and ASP.NET Web Services, which uses Linq to SQL to get data from my SQL Server database. Randomly when the user causes an action to get information from any of my web service methods, Silverlight throws the exception "The remote server returned an error: NotFound.", of type "CommunicationException", with the InnerException status of "System.Net.WebExceptionStatus.UnknownError". Almost 10% of requests gets this error. If the user tries to get the same information again, normally the request has no erros and the user gets the data. When debugging in Visual Studio only Silverlight stops on the exception, and I see no reason for the web service not being found.

• iPhone web apps running as native apps

  - by Henrikb4

  The browser on the iPhone is capable of using advanced web technologies introduced in HTML5. One of these is the app cache that allows web pages to run on the client, from the cache, without a connection to the internet. Together with Local Storage you can also save data permanently "in" the page. My question is, would it then be possible to make a website that when visited and set as a web clip (bookmark on the home screen), could be accessed again, at any moment. Using HTML5, Javascript and css, you can make some very good apps and at the same time avoid the pricey developer fee, the harsh app approval and the single platform development platform? Or am I just dreaming?

• How to unit test C# Web Service with Visual Studio 2008

  - by Steven Behnke

  How are you supposed to unit test a web service in C# with Visual Studio 2008? When I generate a unit test it adds an actual reference to the web service class instead of a web reference. It sets the attributes specified in: http://msdn.microsoft.com/en-us/library/ms243399(VS.80).aspx#TestingWebServiceLocally Yet, it will complete without executing the test. I attempted to add the call to WebServiceHelper.TryUrlRedirection(...) but the call does not like the target since it inherits from WebService not WebClientProtocol. Thanks, Steven

• Security and authentication in web services

  - by King

  Lets say we have a website that uses a web service for all of its functionality (i.e. retrieving and updating data from/to db), how does the web service authenticate requests? As I understand it, in a traditional java "website" a user provides a username & password, and upon validation a jsessionid is assigned to the user (client browser). Every time the client browser asks the website for something, the site checks for the jsessionid ensuring that the user is registered and authenticated. Is there a web services equivalent of this? If yes, what?

• How do web crawlers affect site statistics?

  - by LM

  What are ways in which web crawlers (both from search engines and non-search engines) could affect site statistics (e.g., when doing AB-testing different page variations)? And what are ways to take care of these problems? For example: Do a lot of people writing web crawlers often delete their cookies and mask their IPs, so that web crawlers often show up as different users each time they crawl the site? What are heuristics to use to recognize that something is a bot? (I'm guessing any sophisticated enough bot can be indistinguishable from a real user, if it wants to -- is this correct?)

• web development with ruby without rails?

  - by kmorris511

  For reasons beyond my control, I'm being tasked with Ruby web development that does NOT use Rails or really any other heavyweight framework such as Merb. I'm wondering if anybody else has encountered this and can recommend best practices or resources that describe best practices for such a problem. I'd like to avoid the dreaded out.print('<td class="foo">'+some_data+'</td>') style of web development. A coworker has suggested Rack as a light framework but the documentation is sketchy and it seems unproven in the market.

• Using the same class in both server and web service

  - by iTayb

  I have classes that are needed in both my web service and my server. For example, I have a class named Order that I'd like to send from my server to the web service and vice-versa. Problem is that the class in the server is Order and the one on the web service is localhost.Order, and it is impossible to convert between them, even though they are built from the very same code. Error is cannot convert from 'Order[]' to 'localhost.Order[]'. What can I do? Thank you very much.

• Best package for basic web-based file manager

  - by alchemical

  I'm looking for a basic web-based file management application. It must have an affordable price, and fairly easy installation would be a plus. ASP.Net / IIS based would be easiest for me to work with. Basically, I'd like it to create a secure web site where myself and a few people can exchange various types of files, etc. I'm looking for a package I can install on my own server rather than a web-based service, as I think I can get more space at a good price point this way. I could go custom coding, but I figure this is such a generic need, there must be something already mature out there at a decent price. What has worked best for you?

• Why are access modifiers on web service proxy methods important

  - by cand

  I'm creating interface to an external web service with C# client generated from WSDL. And in this client class I have methods with signature like: public ResponseType InvokeMethod(RequestType request). I want to change its access modifier to protected, but then web service responds with "web service method name is not valid" exception. Do You know why is that so? I understand that maintaining method name can be important for some reasons, but why can't I change this access modifier? Shouldn't it be a matter of my code what access I want to give to this method? Thanks for all the answers in advance.

• Linq to SQL Web Service XML

  - by Bryan

  I built a .NET web service connecting to an MSSQL database. There is a web service call GetAllQuestions() that will not change. I saved the result of GetAllQuestions to GetAllQuestions.xml in the local application folder and set it to content. Normally I would get the result of the web service like this: var myService = new SATService(); var serviceQuestions = myService.GetAllQuestions(); I want to try something like: var serviceQuestions = File.Open("GetAllQuestions.xml"); Any suggestions are much appreciated!

• Bad http connection (400) from Simple Native Iphone App to test .net Web Service

  - by leo

  Dear all, I have written a simple hello world .net web service which will accept 2 parameters and return the parameters as a string. The web service is hosted by IIS on a windows xp pc. I am able to access the web service using safari on the iphone simulator, successfully tested the operation using HTTP POST by clicking the "invoke" button. However, when I use the native app on the iphone simulator, I keep getting a bad http connection error 400 on the IIS log. I have tested my native app with http://viium.com/WebService/HelloWorld.asmx and it works. I have already added Does anyone know what is wrong? Is it some settings that have not configured correctly? Thank you very much in advance.

• Web Services vs Persistent Sockets

  - by dsquires

  I plan on doing a little benchmarking around this question, myself. But I thought it would be good to get some initial feedback from "the community". Has anyone out there done any analysis regarding the pros and cons of these two technologies? My thoughts: Opening and closing TCP/IP connections for web service calls is relatively expensive compared to persistent connections. Dealing with intermittent connection errors and state, etc... would be easier with a web service based framework. You don't see World of Warcraft using web services. One question that I can't seem to find much of answer for anywhere (even on here)... are the limits on the # of persistent connections a single network card can support, etc?

• Asynchronous email processing in Java web application

  - by Denise

  Hi everyone, I would like to implement asynchronous email sending in my web application when users register for a new account. This is so that if there is a problem or delay in sending the email message (e.g. the mail server is down or the network connection to the mail server is slow) the user won't be kept waiting for the sending to complete. My web app is built using Spring and Hibernate's implementation of JPA. What would be the best and most reliable way for me to implement asynchronous email processing in this web application? I am thinking about persisting the email information in a database table which is then regularly polled by a Quartz (http://www.opensymphony.com/quartz/) scheduled job for updates and when it finds new unsent emails, it attempts to send them. Is this a reasonable way of implementing what I want? Thanks.

• TryGetObjectByKey... empty ObjectSets

  - by Rickjaah

  When I use TryGetObjectByKey on my ObjectContext, it returns an error. An item with a duplicate value already exists. When I look at my objectContext, I see that the ObjectSets are empty. What Am I doing wrong... When I enumerate the ObjectSet by hand, by using ToArray on it, or by using the debugger, it does work. LazyLoadingEnabled = true. I reuse 2 tables from another EDMX, but they are in different namespaces and they are not the objectSets i try to approach.

• Higher than high-level web frameworks or CMS's?

  - by Ben

  I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.

• Web Services: Secure? Asp.net

  - by Jacques

  Hey there, Something I can't wrap my head around is how secure web services are. For example we're writing a desktop application that will interact with data on one of our websites as well as local data. This data is sensitive though and the last thing we want is anybody calling the web services. I've not yet found anything that says web services has some kind of authentication methods and the only security I've seen people talk about is using certificates to encrypt the message. I'm no guru on this and would appreciate anyone's input and perhaps a link to somewhere that will explain this in simple terms. Thanks Jacques

• EF 4 - associations with keys that dont match

  - by Steve Ward

  We're using POCOs and have 2 entities: Item and ItemContact. There are 1 or more contacts per item. Item has as a primary key: ItemID LanguageCode ItemContact has: ItemID ContactID We cant add an association with a referrential constraint as they have differing keys. There isnt a strict primary / foreign key as languageCode isnt in ItemContact and ContactID isnt in Item. How can we go about mapping this with an association for contacts for an item if there isnt a direct link but I still want to see the contacts for an item? One of the entities originates in a database view so it is not possible to add foreign keys to the database Thanks Stephen Ward

• What every web developer should know?

  - by arikfr

  Let's say you got a new intern, who's a third-year CS student. He has firm knowledge of the basics, has some experience with C/Java from the courses he took and a lot of desire to learn more. What would you teach him in order to become a good web developer? What I had in mind is: HTML/CSS and the importance of writing semantic markup Javascript, some JS framework (jQuery), JSON Basics of Git/Subversion (whatever you use) The language we use (Ruby, Python, PHP, C#, whatever) Introduction the web framework we use (Rails, Django, ASP.NET MVC...) MVC - what/why/who RESTful web services - how to consume them and how to create one What's on your list?

• WEB-INF/lib jars not found in JBoss 4.0.2 war deploy

  - by boongywoongy

  I have a simple web application (one jsp and one servlet) file that I've copied into jboss-4.0.2/server/default/deploy folder and it has successfully hot deployed as I can access the jsp page. However, when I invoke the servlet, I am getting a java.lan.NoClassDefFoundError. I suspect that the jars under the WEB-INF/lib directory within the war is not being picked up. The structure of my war is: META-INF --> MANIFEST.MF WEB-INF --> classes --> ...*.classes --> lib --> jcommon-1.0.16.jar jfreechart-1.0.13.jar servlet-api.jar index.jsp Anybody else have classloading issues in JBoss 4? Many thanks.

• EF4 CTP5 - Map foreign key without object references?

  - by anon

  I feel like this should have a simple answer, but I can't find it. I have 2 POCOs: public class Category { public int Id { get; set; } public string Name { get; set; } } public class Product { public int Id { get; set; } public int CategoryId { get; set; } } Notice that there are no object references on either POCO. With Code-First, how do I make EF4 CTP5 define a relationship between the two database tables? (I know this is an unusual scenario, but I am exploring what's possible and what's not with Code-First)

• 'Generic' ViewModel

  - by Ian MacPherson

  Using EF 4, I have several subtypes of a 'Business' entity (customers, suppliers, haulage companies etc). They DO need to be subtypes. I am building a general viewmodel which calls into a service from which a generic repository is accessed. As I have 4 subtypes, it would be good to have a 'generic' viewmodel used for all of these. Problem is of course is that I have to call a specific type into my generic repository, for example: BusinessToRetrieve = _repository .LoadEntity<Customer>(o => o.CustomerID == customerID); It would be good to be able to call <SomethingElse>, somethingElse being one or other of the subtypes), otherwise I shall have to create 4 near identical viemodels, which seems a waste of course! The subtype entity name is available to the viewmodel but I've been unable to figure out how to make the above call convert this into a type. An issue with achieving what I want is that presumably the lambda expression being passed in wouldn't be able to resolve on a 'generic' call ?

• How does Alpha Five Version 10 Rate for Web App Development

  - by Gary B2312321321

  I came across this RDMS via the advert on stackoverflow. Seems to be in the vein of MS Access / Filemaker / Apex database development tools but focused on web based applications. It quotes rave reviews from EWeek and a favourable mention from Dr Dobbs regarding its ability to create AJAX web applications without coding. The Eweek review, apparently written by an ASP.NET programmer, goes on to proclaim the ease at which apps can be extended using the inbuilt XBasic language and how custom javascript can easily be added without wading through code. Has anyone here built a web app with Alpha 5? Does anyone have comments on the development process, the speed of it or limitations they encountered along the way? To me it seems Oracle APEX comes closest to the feature set, has anyone programmed in both and have any comments?

• EF4 and multiple abstract levels

  - by Cedric

  I need to use inheritance with EF4 and the TPH model created from DB. I created a new projet to test simples classes. There is my class model: There is my table in SQL SERVER 2008 : VEHICLE ID : int PK Owner : varchar(50) Consumption : float FirstCirculationDate : date Type : varchar(50) Discriminator : varchar(10) I added a condition in my EDMX on the Discriminator field to differentiate the Scooter, Car, Motorbike and Bike entities. MotorizedVehicle and Vehicle are Abstract. But when I compile, this error appears : Error 3032: Problem in mapping fragments starting at lines 78, 85:EntityTypes EF4InheritanceModel.Scooter, EF4InheritanceModel.Motorbike, EF4InheritanceModel.Car, EF4InheritanceModel.Bike are being mapped to the same rows in table Vehicle. Mapping conditions can be used to distinguish the rows that these types are mapped to. Edit : To Ladislav : I try it and error change to become it for all of my entities : Error 3034: Problem in mapping fragments starting at lines 72, 86:An entity is mapped to different rows within the same table. Ensure these two mapping fragments do not map two groups of entities with overlapping keys to two distinct groups of rows. To Henk (with Ladislay suggestion) : There are all of mappings details : What's wrong ? Thanks

• Learning web development as I go

  - by Matt Luongo

  Hey everybody, I've been seriously preparing to take the entrepreneurship leap. I've got a great partner, and we're going to take on some minor funding, and do the thing. Our product is web-based- I'll deem it YAWA (Yet Another Web Application). Both my partner and I have database and web development experience, and I've had a front-end developer in mind for a while. Except, well- he just bowed out. I know a fair amount about the associated technologies (XHTML, CSS, Javascript and some JQuery) interface-side, but I've never had to deal with real-world scenarios, eg cross-browser design. Am I going to be able to survive without this guy? Is it realistic to believe that I can learn the details as I go?
