• Apache reverse proxy: no protocol handler

  I am trying to configure a reverse proxy with apache, but I am getting a No protocol handler was valid for the URL error, which I do not understand.

• How do I generate C# code from WADL files?

  - by Anders Sandvig

  I am looking for a code generator than can generate C# code to access RESTful web services described by WADL files in a way similar to how wadl2java works. Doing som searching I came across the rest-api-code-gen project on Google Code, but although the latest source does in fact support C#, the REST Describe & Compile demo site does not. (The C# button is there, but it's disabled.) I realize I could download the source and set up my own server with the latest version, but I would prefer not to, as what I need is a command line tool and not a web application with dependencies to Google Web Toolkit. I guess I could write my own a command line tool based on the same source code, but if it has already been done, or other tools can do the job, I'd rather avoid it. So, I'm wondering, are there any tools like that out there?

• Setting up Metro 2.0 with Jetty 7

  - by trojanfoe

  This question relates to a previous question of mine. I am attempting to set-up a low overhead Web Container using Jetty 7 that I can deploy Web Services using Metro 2.0. I have installed the following Metro 2.0 libs into jetty/lib: webservices-extra-api.jar webservices-extra.jar webservices-rt.jar webservices-tools.jar And the following into a new jetty/lib/endorsed directory: jsr173_api.jar webservices-api.jar I start Jetty with the following script (Windows) to ensure that jetty/lib/endorsed is part of the 'endorsed library path' and to ensure that Jetty adds the webservices jars to its classpath: @echo off set JETTY_HOME=C:\dev\jetty-7.1.0 set JAVA_OPTS=-Xmx1024m -XX:MaxPermSize=512m -Djetty.home=%JETTY_HOME% -Djava.endorsed.dirs=%JETTY_HOME%\lib\endorsed -Djetty.class.path=%JETTY_HOME%\lib\webservices-rt.jar;%JETTY_HOME%\lib\endorsed\webservices-api.jar -DSTOP.PORT=8079 -DSTOP.KEY=jettykey pushd %JETTY_HOME% java %JAVA_OPTS% -jar start.jar popd However when I deploy a WebServices war file (for example Metro sample 'pricequote'), I get the following exception: java.lang.ClassNotFoundException: com.sun.xml.ws.transport.http.servlet.WSServletContextListener Can anyone help me with this please? I suspect it's related to the order of classes in Jetty's classpath?

• ASP.Net SSRS Report Viewer 9.0 and Report Viewer 10.0 Side-By-Side

  - by user333541

  We are rolling out a large deployment of SQL Server Reporting Services Reports and our platform is SQL Server 2005 so our Report Server is version 2005 running in Native mode. Our web application uses server reports rendered in the Report Viewer 9.0 control. We want to be able to use local reports based on the 2008 RDL spec to create some dashboard applications. We also would like to use the new report viewer 10.0 to viewer these reports. Is there a way to run these both Side-By-Side in the same project? If so how would we go about that? Create a custom server control?

• SOAP Web Service method naming conventions

  - by dbguy

  Consider a Web Service (e.g. SOAP-based) that has an operation which accepts a bulk of data from the client. From the server's point of view it is receiving data, but from the client's point of view it's sending data. How should that operation be named? The options are ImportData ExportData / SendData Is there a de facto standard for naming these things? How do web services usually name these? Thank you for your opinions.

• WCF Data Service Exception

  - by Ravi

  Hi, I am working on C#.Net with ADO.NET Dataservice WCF Data Services. I try to update one record to relational table, when I reach context.SetLink() I am getting exception("The context is not currently tracking the entity"). I don't know how to solve this problem. My code is specified below. LogNote dbLogNote =logNote; LogSubSession dbLogSubSession = (from p in context.LogSubSession where p.UID == logNote.SubSessionId select p).First<LogSubSession>() as LogSubSession; context.AddToLogNote(dbLogNote); dbLogNote.LogSubSession = dbLogSubSession; context.SetLink(dbLogNote, "LogSubSession", dbLogSubSession); context.SaveChanges(); Here LogSubSession is a primary table and LogNote is a foreign table. I am updating data into foreign table based on primary key table. Thanks

• HTTP Content-Type in ASP.Net SoapHttpClientProtocol

  - by Daniel Fone

  Hi there, I have a problem with a Web Service Consumer written in ASP.NET. The error message is: System.InvalidOperationException: Client found response content type of 'application/xml; charset=utf-8', but expected 'text/xml'. The client is based on System.Web.Services.Protocols.SoapHttpClientProtocol. We can't change the Content-Type given by the provider, this has to be 'application/xml; charset=utf-8'. Is there any way to change what Content-Type the SoapHttpClientProtocol expects? Unfortunately, we are probably limited to .NET 1.1. Thanks! Update: We found a way to change the Content-Type sent by the provider, and this solved the problem. I'd still be curious to know how to change the expectations of the consumer though.

• Sporadic name resolution failure happening on web service call

  - by ansleygal

  One of our wcf service applications calls a seperate third party web service to submit information. We are getting the following error every so often, but not all the time: System.Net.WebException: The remote name could not be resolved: 'ws.examplesite.net' at System.Net.HttpWebRequest.GetRequestStream() at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) The wierd thing is that after the error happens, we can hit "Submit" again a second later and it will go through just fine. We have checked and double checked with our network guys and they have confirmed that DNS is correct, and they have done multiple nslookups in a row to confirm. This is happening in all environments (dev, test and prod). We use the third party test and prod urls, and it is happening when we point to both. Does anyone have any other trouble shooting techniques for this or any reason this would happen? Much thanks, ~Ansley

• Lost parameter calling WS from PHP

  - by Zyd

  Hi, I'm trying to call this WS from PHP: namespace WsInteropTest { /// <summary> /// Summary description for Service1 /// </summary> [WebService(Namespace = "http://advantage-security.com/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class TestWs : System.Web.Services.WebService { [WebMethod] public string HelloWorld(int entero) { return "Hello World " + entero.ToString(); } } } The code i use to call the WS is this: <?php require_once('nusoap\nusoap.php'); $client = new nusoap_client('http://localhost/testws/TestWS.asmx?WSDL'); $params = array( 'entero' => 100 ); $result = $client->call('HelloWorld', array($params), 'http://advantage-security.com/HelloWorld', 'http://advantage-security.com/HelloWorld'); print_r($result); ?> and the result is this Hello World 0 What do you think may be the problem? According to what i've read there is no issues with simple types between .NET (which are converted to standard soap types) and PHP. If it is of use, here it is the WSDL.

• wcf data service security configuration

  - by Daniel Pratt

  I'm in the process of setting up a WCF Data Services web service and I'm trying to sort out the security configuration. Although there's quite a lot of documentation out there for configuring WCF security, a lot of it seems to be outmoded or does not apply to my scenario. Ultimately, I am planning on managing authorization of operations via change interceptors. Thus, all I really need is the simplest way to permit a client to pass credentials along with a request and to be able to authenticate those credentials against either AD or an ASP.NET membership provider (I'd much prefer the latter unless it makes things much more complicated). I'm intending to manage encryption at the transport level (i.e. HTTPS). I'm hoping that the eventual solution does not involve a huge web.config. Likewise, I'd much prefer to avoid writing custom code for the purpose of authentication.

• Moving from WCF RIA Beta to RC: best practices?

  - by Duncan Bayne

  I have an existing WCF RIA project built on the Release Candidate; I'm now moving to the Release version & have discovered many changes. David Scruggs made the following comment on his (MSDN) blog: "If you’ve written anything in SIlverlight 4 RIA Services, you’ll need to rewrite it. There has been a lot of refactoring and namespace moves." Having made a brief attempt to compile the old solution with the new RIA framework I'm inclined to agree. My current plan is to: remove the Silverlight Business Application projects from the Solution rebuild the EF4 items from the database create a new Silverlight Business Application project re-add the files (XAML, CS) from the old Silverlight Business Application project Does this sound like a reasonable approach? I think it's cleaner than trying to manually alter the existing project.

• How to call web service with Android

  - by BobbyShaftoe

  I am having a lot of trouble finding good information on how to call a standard SOAP/WSDL web service with Android. All I've been able to find are either very convoluted documents and references to "kSoap2" and then some bit about parsing it all manually with SAX. ... Ok, that's fine but it's 2008 so I figured there should be some good library for calling standard web services. The Web Service is just basically one created in NetBeans. I would like to have IDE support for generating the plumbing classes. I just need the easiest/most-elegant way to contact a WSDL based web service from an Android based phone. Thanks.

• Comparison of ASP.Net Reporting Solutions

  - by Brian MacKay

  This week my team spent way too much time trying to do simple things in reporting services, and I've decided to start evaluating other options. I know there are some good options out there now that aren't too expensive. I've heard that Telerik, ActiveReports, and a few others are widely used. I was hoping to get some first hand accounts regarding reporting tools that you've used. Specifically, I definitely want to hear your thoughts about: Pain points and gotchas you ran into. Ease of use for report design. It's a little bizarre to me that Access still seems to hold the throne in this area! What's your favorite tool? Anything I've missed that seems important to you. Thanks a lot!

• WCF performance improvements

  - by Burt

  I am developing a WPF application that talks to a server via WCF services over the internet. After profiling the application I noticed a lot of time is being taking up by creating the appropriate WCF client proxy and making the call to the server. The code on the server is optimised and doesn't take any time to run yet I am still seeing a 1.5 second delay from when a service is invloked to it returning to the client. A few points to give a bit of background: I am using the ASP.Net membership for security I will eventually hook into the same server side code through a website I would eventually like to have offline support in the application I really need to nail the performance early though as if the app is taking a couple of seconds to come back it is too long for what I am trying to do. Can anyone suggest performance tips that will help me please?

• Which web containers install themselves well as a Windows service?

  - by Thorbjørn Ravn Andersen

  We have had a web application product for several years, and used Tomcat to deploy it under Windows as it registers itself as a Windows service so it starts and stops automatically. We may now happen to need more JEE facilitites than is provided by Tomcat (we are very tempted by the JEE 6 things in the container) so the question is which Open Source JEE containers works well as Windows services. Since Glassfish is the only JEE 6 implementation right now, it would be nice if it works well, but I'd like to hear experiences and not just what I can read from brochures. If not, what else do people use? EDIT: This goes for web containers too, and not just JEE containers. We will probably keep the necessary stack included until we find the right container and it gets JEE6 support. EDIT: I want this to work as distributed. I'm not interested in manually hacking wrappers etc., but want the installation process to handle the creation and removal of the service.

• Spring 3 JSON with MVC

  - by stevedbrown

  Is there a way to build Spring Web calls that consume and produce application/json formatted requests and responses respectively? Maybe this isn't Spring MVC, I'm not sure. I'm looking for Spring libraries that behave in a similar fashion to Jersey/JSON. The best case would be if there was an annotation that I could add to the Controller classes that would turn them into JSON service calls. A tutorial showing how to build Spring Web Services with JSON would be great. EDIT: I'm looking for an annotation based approach (similar to Jersey). EDIT2: Like Jersey, I am looking for REST support (POST,GET,DELETE,PUT). EDIT3: Most preferably, this will be the pom.xml entries and some information on using the spring-js with jackson Spring native version of things.

• client ip address in ASP.NET (.asmx) webservices

  - by Zain Shaikh

  I am using ASP.Net (.asmx) web services with Silverlight. since there is no way to find client ip address in Silverlight, therefore I had to log this on service end. these are some methods I have tried: Request.ServerVariables(”REMOTE_HOST”) HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"] HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; Request.UserHostAddress() Request.UserHostName() string strHostName = System.Net.Dns.GetHostName(); string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(0).ToString(); All the above methods work fine on my local system, but when I publish my service on production server. it starts giving errors. Error: Object reference not set to an instance of an object.

• Using Silverlight 4 with ODBC

  - by user1384831

  I'm completely new to Silverlight and I want to connect to a Netezza database with an ODBC connection and pull records to display nicely in Silverlight. What's the easiest way to do this? From some research, it seems creating a WCF RIA service is what most people do ( http://www.codeproject.com/Articles/354715/Creating-a-WCF-RIA-Services-Class-Library-for-a-Si ) but the process seems a bit convoluted. Coming from an ASP.net background, could I do something simpler like creating an ODBC connection in the code-behind (using System.Data.ODBC functionality), executing a query, storing the returned records in a Datatable and then binding that to some Silverlight control?

• Install windows service "Service ... was not found on computer '.'."

  - by Chau

  I'm trying to create my first Windows Service in C# VS2010 and slowly discover how I should do things. But now I have reached a point, where I cannot install a new version of my service. My setup program tells me Error 1001. Service MyService was not found on computer '.'. --> The specified service does not exists as an installed service. The last part of the message is translated into english from danish. I cannot see the service in either the service list (services.msc) or in the registry. I have removed the left overs from a previous installation, so no traces here either. I have emptied the temporary folder under my windows account. Where do I locate the rest of the remains obstructing my installation of the service?

• Testing input fields not available for web service in Visual Web Developer Express

  - by Rob Segal

  I have a web service that I am trying to test in Visual Web Developer Express Edition (Service Pack 1). I am working with two different websites on two different branches from an SVN repository but largely the same code. The web services are the same code but there are some code differences for other features. My problem is that when going to the web service specification page in debug mode (i.e. MyWebService.asmx) there should be text fields for inputting parameters for that web service. On one of these web sites the fields are available. On another they are not available. I don't understand why/how there should be any differences between the two setups.

• What does "enterprise" means in relation to software architecture?

  - by SkonJeet

  I see the term "enterprise" being thrown around software developers and programmers a lot and used loosely it seems. en·ter·prise/'ent?r?priz/ Noun: A project or undertaking, typically one that is difficult or requires effort. Initiative and resourcefulness. Can someone please clarify what this term actually encompasses? "At an enterprise level", "enterprise scale"? There are even "enterprise editions" of things. What exactly does it mean? It obviously doesn't make sense judging by the above definition so more specifically to software what does one mean when using the word enterprise? EDIT: To add a spin on this - how does this term then fit into phrases such as Enterprise Framework Model? What does data access and data context have to do with company-wide descriptions?
