• What is the difference in WCF when using KnownType and ServiceKnownType?

  - by Paul Speranza

  I have a service that returns an array of animal but the list can contain cats, dogs, etc, which all extend animal. I know I need to use either the KnownType or ServiceKnownType attribute, and on the entity class or the service class, respectively. What is the difference between the 2 attributes? I prefer the ServiceKnownType because it is applied on the service, exactly where it is needed and called for, as opposed to KnownType which is applied on my entity. To me applying it on the entity class means knowing too far ahead how my entity class is being used. For now I have it on my entity and it works like a charm, but I am looking for guidance here as to best practices and usefullness. Thanks, Paul Speranza

• Create a Shortcut to Put Your Windows Computer into Hibernation

  - by Mysticgeek

  Putting your Windows computer into Hibernation Mode allows you to save power, and quickly access your desktop again when you need it. Here we show how to create a shortcut to put your PC in Hibernation Mode quickly. Note: Here we show how to create the shortcut in Windows 7 and add it to the Taskbar. But creating the shortcut should work in XP and Vista as well. Create Shortcut  Right-click an empty area on your desktop and select New \ Shortcut from the Context Menu. In the Create Shortcut window type or copy the following in the location field… C:\Windows\System32\rundll32.exe powrprof.dll, SetSuspendState 0,1,0 Now give the shortcut a name such as Hibernate Computer or whatever you want to call it. Now you have the shortcut on your desktop, but you might want to change the icon to something else. Change Shortcut Icon Right-click the shortcut icon and select Properties. Select the Shortcut Tab and click the Change Icon button. In the Look for icons in this file field copy and past the following then click OK. %SystemRoot%\system32\SHELL32.dll This brings up a list of included Windows icons you can choose from. Select whatever you want it to be. There are a couple of Power icons in the directory…click OK. Of course you can choose any icon you want, if you customize your icons just browse to the directory they are in. For more on selecting icons check out our article on how to customize your icons in Windows 7 or how to change a file type’s icon. Now you will see the icon in the Shortcut Properties window, click OK. Here we have a nice looking shortcut that you can use to put your machine into Hibernation. Or here we used a customized Star Trek icon just to make things more interesting… You can pin the shortcut to the Taskbar for easy access. Conclusion If Hibernation is not enabled on your Windows 7 system you can easily manage it. By creating a shortcut and pinning to the Taskbar, it allows you to put your machine into Hibernation Mode quick and easy.

• Novell Netware 6 and C#

  - by user317744

  Hi, I don't know if anyone has any expertise with Novell Netware or not, but I situation where one of my clients is getting a weird error trying to move a file to a netware share. The situation is pretty complicated but I'll try and outline it as best I can. 1) The application is running as a service 2) The file to be moved is a local file in an accessible location (to the service) 3) The file is being moved with FileInfo.MoveTo(). 4) The MoveTo is throwing an IOException and the message is "a device attached to the system is not functioning". I'm at a loss as to explain what might be happening. On a side note, it seems that running a small test program interactively using the same method (FileInfo.MoveTo) to the same location works fine so it seems to be associated with the service itself. Any help would be hugely greatful. Thanks. Kristofor Wilson

• Guide to Downloading Oracle Fusion Middleware 11g Products

  - by Daniel Mortimer

  IntroductionThe idea of writing a blog about downloading software seems a bit strange .. right? After all, surely just give me the web download link and away I go!? Unfortunately, life is not so simple if you are a DBA or Systems Administrator tasked with staging Oracle Fusion Middleware 11g products for your chosen business technology stack. Here are the challenges: Oracle Fusion Middleware is not a single product, it is a family of products - a media pack with many many "disks" - which ones do I pick? Are the products I pick certified / supported on my chosen platform? Which download site do I use? I need to be on the latest and greatest - how do I get hold of the latest product patch set? The purpose of this blog is to give you a roadmap to get you through these challenges. Oracle Fusion Middleware 11g - A Product SuiteThe first thing to appreciate is that Oracle Fusion Middleware 11g is not a single product. It is a product suite, an umbrella label for many products. Typically you don't download the whole media pack - well not unless you want to stage 124 Parts - a total of 68 Gig  - instead you pick the pieces that are required for your chosen Middleware solution. Therefore, you need to research / understand which products are required to build your solution. In this respect, before you go looking for the software pick and persue the product guide from the table below which matches your situation:  Installing a New / Vanilla FMW 11g architecture Oracle Fusion Middleware Installation Planning Guide 11g  Upgrading Oracle Application Server 10g to FMW 11g Oracle Fusion Middleware Upgrade Planning Guide 11g  Patching an existing FMW 11g architecture Oracle Fusion Middleware Patching Guide 11g Certification Information Ok, so now you have an idea of what Fusion Middleware products you need. It's time to check whether these products are certified against your chosen platform. There are two places to find this information:My Oracle Support Certification Tab PageFigure 1.1 My Oracle Support Certification Tab Page - "Search on SOA Suite" Figure 1.2 My Oracle Support Certification Tab Page - "SOA Suite Search Result" The FMW 11g Certification Central Hub (in the format of xls spreadsheet)Figure 2: Screenshot of FMW 11g Release 1 Certification xls spreadsheet Hints / Tips: Fusion Middleware 11g certification information has only recently been added into the Certification Tab page and I think it is the more friendly way to access the information. However, due to some restrictions with the Certification Tab page interface some of the more, let's say obscure certification information, is still to be only found in the Certification spreadsheet. Be aware that to find certification information via the My Oracle Support Certification Tab page you must enter the FMW 11g product name e.g. "Oracle SOA Suite". Do NOT enter "Oracle Fusion Middleware". The certification information does not exist at this product suite level.  For example, if you are building a solution which includes Oracle SOA Suite Oracle WebCenter then you will have to look up the certification information for each product in turn.After choosing the product name, select the latest patch set version. This will not only tell you whether your chosen product is available at that patch set version but provide the certification information relevant to that version.  If the product is not available under the latest patch set version, seek the information under previous patch set versions. Important: Make a careful note of the Oracle WebLogic Server version which is certified with your chosen product and patch set version. Oracle WebLogic Server is the core component of a Oracle Fusion Middleware 11g home. It is important therefore to ensure later on that you download the version of Oracle WebLogic Server which is compatible and certified with your chosen product and patch set version.Also - sorry to state the obvious, but please do not take certification information from the screenshots above. The screenshots are only good for the time they were entered into the blog. To ensure you have the latest information, interactively look up the certification details. For more information about finding certification information, bookmark and readMy Oracle Support Certification Tool for Oracle Fusion Middleware Products [Doc ID 1368736.1]How to Find Certification Details for Oracle Application Server 10g and Oracle Fusion Middleware 11g [Doc ID 431578.1] Downloading the Software Now you should be ready to download the software. There are two download locations Oracle Software Delivery Cloud (formerly known as E-Delivery)Figure 3 - Screenshot of Fusion Middleware Download from Delivery CloudOracle Fusion Middleware Download Page on Oracle Technology NetworkFigure 4 - Screenshot of OTN Product Download Screen Hints / Tips: Your choice of download location should be primarily driven by your licensing needs. Take note of the wording on the OTN site - to quote:"The downloads below are provided for evaluators under the OTN License Agreement. Licensed customers should download their software via our Oracle Software Delivery Cloud site, which offers different license terms."However, it has to be said that the presentation of the most of the product download pages on OTN does make the job easier. The Software Delivery Cloud provides you with a flat list of the Oracle Fusion Middleware 11g media pack. You have to know what you are looking for and pick out the right pieces :-( The OTN product download pages present not only the download for the product you want but also its dependencies such as WebLogic Server and Repository Creation Utility. So, even if your licensing requirements drive you towards the cloud, it is still worthwhile checking the OTN pages if only as a guide to what you need to pick out from the flat list found on the cloud site. Latest Patch Set This is an area which may cause you confusion - especially if you are more familiar with the Oracle Application Server 10g patching story. From Patch Set 11.1.1.6 and higher, the majority of FMW 11g products (N.B there are exceptions) provide installers which can be used both to update existing FMW 11g product installs or build brand new ones. This is good news because, unless you are dealing with one of the exceptions, it means you do not have to download base software and a patch set. At the time of the writing, the two significant exceptions are: Portal/Forms/Reports/Discoverer 11g Release 1 (11.1.1.x) Identity Access Management 11g Release 1 (11.1.1.x) The other key message here is ensure you are grabbing a version of Oracle WebLogic Server which is compatible with your chosen product patch set version. Get this wrong and you will hit errors / problems at AS Instance Configuration Time.The go to place is this document - Oracle Fusion Middleware Download, Installation, and Configuration Readme FilesIn fact, this README document pretty much takes you through what I have blogged above. The only thing is you need to know which README to choose, and that's why planning your FMW 11g technology stack and viewing certification information comes into play beforehand. And Finally As the Oracle Fusion Middleware Download, Installation, and Configuration Readme Files states don't forget to check FMW 11g System Requirements FMW 11g Product Interoperability

• Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data

  - by joebeazelman

  I created an assembly containing WCF service code and dropped into another web project. When I try to invoke a service method, I get the following inner exception: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. Why this is happening? My newly created assembly lives inside the ASP.NET /bin folder along with other assemblies. At this level, should the database not know or care whether it is being called from a web service or from a normal call? How would it know that my assembly is foreign? How do I resolve this issue?

• Workflow Foundation 4 - DeclarativeServiceLibrary - Error while calling second ReceiveAndSendReply

  - by dotnetexperiments

  Hi, I have created a DeclarativeServiceLibrary using VS2010 beta 2, Please check this image of Sequential Service Following is the code used to call these two activities ` int? data = 123; ServiceReference1.ServiceClient client1 = new ServiceReference1.ServiceClient(); string result1 = client1.GetData(data); //This line shows error :( string result2 = client1.Operation1(); Response.Write(result1 + " :: ::" + result2);` client1.GetData works perfectly, but client1.Operation1 show the following error. Please let me know how to fix this. There is no context attached to the incoming message for the service and the current operation is not marked with "CanCreateInstance = true". In order to communicate with this service check whether the incoming binding supports the context protocol and has a valid context initialized.

• Getting Current with Visual Studio 2010 for Web Developers

  - by plitwin

  I don't know about you, but I find it kind of crazy at times figuring out if I have the latest of everything there is for the Visual Studio 2010 developer from Microsoft. (This does not include any third-party components, just recommended updates from Microsoft.) And the be honest, the msn.microsoft.com and asp.net sites are not that helpful in figuring this out.In an effort to help, I have enumerated here what the latest VS 2010 setup should include, complete with download links. When you install everything here, you will be able to develop ASP.NET 4.0 Web Forms and ASP.NET MVC 3 applications and web sites in addition to the other stuff your version of Visual Studio supports (e.g., Silverlight, WPF, etc.). These downloads will also include NuGet and the Entity Framework 4.1, so there is no need to download this software separately.Visual Studio 2010. First of all, you need to purchase and install Visual Studio 2010 itself. For the free Express version, you can download it from Visual Web Developer 2010 ExpressVisual Studio Service Pack 1 (released Spring 2011).This is a must-have download that fixes a bunch of bugs and a number of enhancements too including preliminary support for HTML5 and CSS3. See #4 below for better support of these web technologies. Download and install from VS 2010 SP1 download page. You can find details on the features of the service pack here. ASP.NET MVC3 Tools Update (released Spring 2011)If you are using ASP.NET MVC 3, then you should also download install this update for Visual Studio from ASP.NET MVC3 Tools Update download page. This update improves Visual Studio's support for MVC 3, including better scaffolding, NuGet, Entity Framework 4.1, and more. A good overview of the updates can be found in Phil Haack's blog post.Web Standards Update for Microsoft Visual Studio 2010 SP1 (released June 2011)This is an update to VS 2010 SP1 that "brings VS 2010 intellisense & validation as close to W3C specification as we could get via means of an extension". Download and install from Web Standards Update download page. A good description of the changes can be found in the Visual Web Developer Team blog post.Note: I don't control these download pages, so it is possible they will change. If so, I will do my best to update these links. This information was current as of June 24, 2011.

• Workflow Foundation 4 WorkflowServiceHost Message Correlation

  - by Lygpt

  I have 2 methods on a workflow service hosted in WorkflowServiceHost. The first method is called and starts the regular workflow sequence - talking to other web services, database work etc but on some occassions will pause and persist to db (as-in the delay activity) and wait for some human action to take place before continuing. I need my second method to be able to hook into this persisted workflow, change a local variable and then continuing processing. I have looked at message based correlation in workflow but can only seem to find examples where some kind of infinite while loop keeps the workflow instance active so that the second service method call can arrive whilst it's still running. Because my workflow instance will be delayed/persisted, the second service call doesn't seem to get anywhere (I can't have an infinite while loop keeping the workflow instance active). I hope this makes sense - cheers!

• C# WMI, Performance Counters, & SNMP Oh My!

  - by Keith

  I have a C# windows service which listens to a MSMQ and sends each message out as an email. Since there's no UI, I'd like to offer an ability to monitor this service to see things such as # messages in queue, # emails sent (by message type perhaps), # of errors, etc. What is the best/recommended way to accomplish this? Is it WMI or performance counters? Is this data viewed using PerfMon or WMI CIM Studio? Does any approach allow one to monitor the service real-time as well as providing historical analysis? I can dig into the details myself but would appreciate some broad guidance to help demystify this subject.

• Reputable geo-ip location Services

  - by Alan Storm

  Who are some of the reputable and/or stable geo-ip location service providers? I'm specing out an application that needs this functionality, and whenever I google geo-ip I get a ton of hits, but it's hard to tell who the legit providers are and who the fly-by-night folks are. Ideally I'd like something that can run without a call to an external API (i.e. regular database updates), but would be interested in hearing about experience with providers who offer live/http services. If it ran in PHP that would be great, but so long as it could run in a *nix environment that's fine. I'd prefer a paid service from a reputable provider than an awesome free service that could vanish tomorrow (free services are welcome, just convince me they're not going to vanish).

• Preserving DataRowState when serializing DataSet using DataContractSerializer

  - by user349453

  For various reasons I am having to send a typed dataset to a WCF service endpoint. This works fine except that upon Deserializing, the RowState of each row in each DataTable is set to 'Added', regardless of what they were on the client. If I write the serialized stream out to a file, I see that the RowState is not part of the Serialized data. How can I add this so that I can preserve the RowState across service boundaries? Not that I think it matters, but the client process is running .net 3.5 while the service process is running .net 4.0

• Logging ASMX Requests and Responses from Client

  - by John

  Hi, I've got a C# web application which I can't easily update the code of. However, I can make configuration changes to the application. The application calls out to a third-party ASMX web service, and I really need (if at all possible) to log the full XML requests and responses. I have no control over the web service so I have to do it from the client. I'm not using WCF - this is standard ASMX web service calls. Is there any way I can log the XML requests and responses from the client web app without having to redeploy the code? Thanks in advance John

• Optional query string parameters in URITemplate in WCF?

  - by Shafique

  I'm developing some RESTful services in WCF 4.0. I've got a method as below: [OperationContract] [WebGet(UriTemplate = "Test?format=XML&records={records}", ResponseFormat=WebMessageFormat.Xml)] public string TestXml(string records) { return "Hello XML"; } So if i navigate my browser to http://localhost:8000/Service/Test?format=XML&records=10, then everything works as exepcted. HOWEVER, i want to be able to navigate to http://localhost:8000/Service/Test?format=XML and leave off the "&records=10" portion of the URL. But now, I get a service error since the URI doesn't match the expected URI template. So how do I implement defaults for some of my query string parameters? I want to default the "records" to 10 for instance if that part is left off the query string.

• ASP.NET 3.5 Routing?

  - by Maushu

  I was looking for a way to route http://www.example.com/WebService.asmx to http://www.example.com/service/ using only the ASP.NET 3.5 Routing framework without needing to configure the IIS server. Until now I have done what most tutorials told me, added a reference to the routing assembly, configured stuff in the web.config, added this to the Global.asax: protected void Application_Start(object sender, EventArgs e) { RouteCollection routes = RouteTable.Routes; routes.Add( "WebService", new Route("service/{*Action}", new WebServiceRouteHandler()) ); } ...created this class: public class WebServiceRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { // What now? } } ...and the problem is right there, I don't know what to do. The tutorials and guides I've read use routing for pages, not webservices. Is this even possible? Ps: The route handler is working, I can visit /service/ and it throws the NotImplementedException I left in the GetHttpHandler method.

• World Record Performance on PeopleSoft Enterprise Financials Benchmark on SPARC T4-2

  - by Brian

  Oracle's SPARC T4-2 server achieved World Record performance on Oracle's PeopleSoft Enterprise Financials 9.1 executing 20 Million Journals lines in 8.92 minutes on Oracle Database 11g Release 2 running on Oracle Solaris 11. This is the first result published on this version of the benchmark. The SPARC T4-2 server was able to process 20 million general ledger journal edit and post batch jobs in 8.92 minutes on this benchmark that reflects a large customer environment that utilizes a back-end database of nearly 500 GB. This benchmark demonstrates that the SPARC T4-2 server with PeopleSoft Financials 9.1 can easily process 100 million journal lines in less than 1 hour. The SPARC T4-2 server delivered more than 146 MB/sec of IO throughput with Oracle Database 11g running on Oracle Solaris 11.

The validation process certifies that the journal entries are accurate, ensuring that ChartFields values are valid, debits and credits equal out, and inter/intra-units are balanced. Once validated, the entries are processed, ensuring that each journal line posts to the correct target ledger, and then changes the journal status to posted. In this benchmark, the Journal Edit & Post is set up to edit and post both Inter-Unit and Regular multi-currency journals. The benchmark processes 20 million journal lines using AppEngine for edits and Cobol for post processes.

• Send parameters in order in HTTPService

  - by Suraj Chandran

  I am trying to work with a simple HTTPService. The problem is that my webservice is conscious of the order of arguments it gets. I will tell the problem with an example: var service:HTTPService = new HTTPService(); var params:Object = new Object(); params.rows = 0; params.facet = "true"; service.send(params); Note that in the above code I have mentioned the parameter rows before facet, but the url I recieve is facet=true&rows=0. So I recieve the argument rows before facet and hence my webservice does not work. I figured out that the contents of array is always sent in alphabetical order, which I dont want. Is there any way I can achieve explict ordering of parameters sent? Note that I am not in power of changing the logic of webservice(its basically a RPC service supporting both desktop and web client). Thanks.

• B64 String Being Stripped From HttpService JSON Object Flex 4.0

  - by user163757

  I am trying to decode some b64 images obtained from a web service in my Flex application. The response of this web service is a basic JSON object, with a property (B64Image) that contains the encoded string. The service works fine from my regular browser, however the b64 string gets stripped. So the object the result handler gets has a null value for B64Image. Anyone see something wrong here? EXPECTED OUTPUT { "PropertyPhotos": [ { "B64Image": "/9j/4AAQSkZJRgABAQEAYABgAAD....etc" } ] } <s:HTTPService id="photoService" url="http://localhost/dev/photohandler.ashx" resultFormat="text" result="photoService_resultHandler(event)" fault="photoService_faultHandler(event)"> </s:HTTPService>
