• HTML input not working correctly with AJAX update panels used else where on page

  - by Sean P

  I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout. Here is my code: <div id="divFileInputs" runat="server"> <input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em" onfocus="AddFileInput()" class="textbox" /></div> <select id="selectFileList" name="ListBox1" size="5" style="width: 50em; text-align: left;" class="textbox" /> <input id="RemoveAttachmentButton" type="button" value="Remove" onclick="RemoveFileInput()" class="removebutton " /> </div> Here is my code behind: Protected Sub CopyAttachments(ByVal issueId As String) Dim files As HttpFileCollection = Request.Files Dim myStream As System.IO.Stream Dim service As New SubmitService.Service For i As Integer = 0 To files.Count - 1 Dim postedFile As HttpPostedFile = files(i) Dim fileNameWithoutPath As String = System.IO.Path.GetFileName(postedFile.FileName) If fileNameWithoutPath.Length > 0 And issueId.Length > 0 Then Dim fileLength As Integer = postedFile.ContentLength Dim fileContents(fileLength) As Byte ' Read the file into the byte array. Send it to the web service. myStream = postedFile.InputStream myStream.Read(fileContents, 0, fileLength) service.ClearQuestAttachToIssue(issueId, fileNameWithoutPath, fileContents) End If Next service = Nothing End Sub When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded. Anyone know how to fix this?

• Enterprise Platform in Python, Design Advice

  - by Jason Miesionczek

  I am starting the design of a somewhat large enterprise platform in Python, and was wondering if you guys can give me some advice as to how to organize the various components and which packages would help achieve the goals of scalability, maintainability, and reliability. The system is basically a service that collects data from various outside sources, with each outside source having its own separate application. These applications would poll a central database and get any requests that have been submitted to perform on the external source. There will be a main website and REST/SOAP API that should also have access to the central data service. My initial thought was to use Django for the web site, web service and data access layer (using its built-in ORM), and then the outside source applications can use the web service(s) to get the information they need to process the request and save the results. Using this method would allow me to have multiple instances of the service applications running on the same or different machines to balance out the load. Are there more elegant means of accomplishing this? i've heard of messaging systems such as MQ, would something like that be beneficial in this scenario? My other thought was to use a completely separate data service not based on Django, and use some kind of remoting or remote objects (in they exist in Python) to interact with the data model. The downside here would be with the website which would become much slower if it had to push all of its data requests through a second layer. I would love to hear what other developers have come up with to achieve these goals in the most flexible way possible.

• Integrated Security on Reporting Services XML Datasource

  - by Nathan

  Hey all, I am working on setting up my report server to use a web service as an XML datasource. I seem to be having authentication issues between the web service and the report with I choose to use Integrated security. Here's what I have: 1) I have a website w/ an exposed service. This website is configured to run ONLY on Integrated Security. This means that we have all other modes turned off AND Enabled anonymous access turned off under directory security. 2) Within the Web.config of the website, I have the authentication mode set to Windows. 3) I have the report datasource set to being an XML data source. I have the correct URL to the service and have it set to Windows Integrated Security. Since I am making a hop from the Browser to the Reporting Server to the Web Service, I wonder if I am having an issue w/ Kerberos, but I am not sure. When I try to access the service, I get a 401 error. Here are the IIS logs that I am generating: 2011-01-07 14:52:12 W3SVC IP_ADDY POST /URL.asmx - 80 - IP_ADDY - 401 1 0 2011-01-07 14:52:12 W3SVC IP_ADDY POST /URL.asmx - 80 - IP_ADDY - 401 1 5 Has anyone worked out this issue before? Thanks!

• Any web services with APIs for outsourcing webapp transactional email? [closed]

  - by Tauren

  My webapp needs to send customized messages to members and I'm wondering if there is an inexpensive and easy to use web service that would meet my needs. The types of mail I will be sending include: New account activation email (sent ASAP) Daily status report of user's account (sent anytime) Event reminders (sent at specific time) Specifically, I would like the following features: RESTful API to add an email message into the send queue A way to add a priority to each message (account signup activations should be sent immediately, while a daily status report could be sent anytime each day) They manage the sending of mail and the processing of bounces Possibly, they manage opt-out/opt-in features They offer features such as DKIM, VERP, etc. If their service determines an address is undeliverable (via VERP or other means, a user unsubscribes, etc), they make a RESTful call to my web service to notify me Nice if they had some reporting features, WebBugs, link tracking, etc. What I am NOT looking for is an email marketing service that caters only to sending out copies of the same mail to masses of recipients. I need to send out unique and custom messages to individuals. I had a chat with MailChimp about using their services for sending these types of messages and they said their service does not support customized emails per recipient. Edit: I just discovered a service called JangoSMTP that appears to meet many of my requirements. It provides an API for sending mail, supports DKIM, bounce management, and even feedback loops. Unfortunately, their idea of inexpensive doesn't mesh with mine, as it would cost $180/mo to send a single daily message to my 1000 users.

• How to add or remove a value inside a table cell on selection / de-selection of checkbox of that row, trying to submit the value via Jquery?

  - by Raul

  Here is the table: <%= form_tag '', :id => "costs" do %> <table class="table table-bordered" id="service_cost"> <% @services.each do |service| %> <tbody> <tr> <td><%= check_box_tag :open_service, {}, false, :class => 'checkable' %></td> <td><%= service.phone %></td> <td><%= service.internet %></td> <td></td> <td></td> <td></td> <td></td> <td></td> <td><%= service.house_keeping %> </td> <td>0.0 </td> <td><%= service.laundry %></td> <td><%= text_field_tag "service_cost", service.total, :class => "input-small" %></td> </tr> <% end %> when the form gets submitted, the javascript gets into action: $("#costs").submit(function(){ formData=$("#costs").serializeArray(); processFormData(formData) return false; }); This ensures form submission on selecting the checkbox: $('.checkable').live('change', function() { $(this).parents('form:first').submit(); }); But, what I am looking for is adding or removing a cell value based on checkbox selection/de-selection and submitting it, kindly suggest a way to do it.

• Running an application from an USB device...

  - by Workshop Alex

  I'm working on a proof-of-concept application, containing a WCF service with console host and client, both on a single USB device. On the same device I will also have the client application which will connect to this service. The service uses the entity framework to connect to the database, which in this POC will just return a list of names. If it works, it will be used for a larger project. Creating the client and service was easy and this works well from USB. But getting the service to connect to the database isn't. I've found this site, suggesting that I should modify machine.config but that stops the XCopy deployment. This project cannot change any setting of the PC, so this suggestion is bad. I cannot create a deployment setup either. The whole thing just needs to run from USB disk. So, how do I get it to run? (The service just selects a list of names from the database, which it returns to the client. If this POC works, it will do far more complex things!)

• Can I legally publish my Fortran 90 wrappers to nVidias CUFFT library (from CUDA SDK)?

  - by Jakub Narebski

  From a legal standpoint (licensing issues), can I legally in agreement with license publish Fortran 90 wrappers (bindings) to CUFFT library from nVidia CUDA Toolkit, under some open source license (either CC0 i.e. public domain, or some kind of permissive license like BSD). nVidia provides only C bindings with their CUDA SDK.

• SQL SERVER – DATEDIFF – Accuracy of Various Dateparts

  - by pinaldave

  I recently received the following question through email and I found it very interesting so I want to share it with you. “Hi Pinal, In SQL statement below the time difference between two given dates is 3 sec, but when checked in terms of Min it says 1 Min (whereas the actual min is 0.05Min) SELECT DATEDIFF(MI,'2011-10-14 02:18:58' , '2011-10-14 02:19:01') AS MIN_DIFF Is this is a BUG in SQL Server ?” Answer is NO. It is not a bug; it is a feature that works like that. Let us understand that in a bit more detail. When you instruct SQL Server to find the time difference in minutes, it just looks at the minute section only and completely ignores hour, second, millisecond, etc. So in terms of difference in minutes, it is indeed 1. The following will also clear how DATEDIFF works: SELECT DATEDIFF(YEAR,'2011-12-31 23:59:59' , '2012-01-01 00:00:00') AS YEAR_DIFF The difference between the above dates is just 1 second, but in terms of year difference it shows 1. If you want to have accuracy in seconds, you need to use a different approach. In the first example, the accurate method is to find the number of seconds first and then divide it by 60 to convert it to minutes. SELECT DATEDIFF(second,'2011-10-14 02:18:58' , '2011-10-14 02:19:01')/60.0 AS MIN_DIFF Even though the concept is very simple it is always a good idea to refresh it. Please share your related experience with me through your comments.

• Scheduled Deprecation of Legacy Obligation Features

  - by Wes Curtis

  The Obligation object in ETPM includes some functionality and tables that, to our knowledge, are not being used by customers and implementers are this time.  Removing this logic and the related tables should benefit the performance of and simplify logic executed during Obligation maintenance processing. The Release Notes included with ETPM v2.3.1 announced that the product plans to deprecate the functionality on Obligation for Contract Terms, Contract Quantities, Tax Exemptions, Terms & Conditions and Obligation Type Start Options.  Our plan is to remove this functionality in the next release of ETPM. We have already confirmed with most project teams that these features are not being used so the deprecation should have no impact on existing designs or process. If you think your project may be impacted by this deprecation, please review any Business Object that has been created for the Obligation maintenance object to make sure that no elements are being defined for any of the following child tables: -          CI_SA_CONTERM -          CI_SA_CONT_QTY -          CI_TOU_CONT_VAL -          CI_SA_TC   As part of this deprecation, the following administrative tables are being removed along with their related metadata: -          Contract Quantity Type -          Tax Exempt Type -          Terms and Conditions Please contact myself or the Oracle Tax Product Management team if your implementation has actually used these objects in their designs. We can discuss options to mitigate impacts of this planned deprecation.  We will continue to announce planned deprecations in the Release Notes for each release and will contact project teams ahead of time to confirm that these deprecations will have little to no impact on our customers.

• What if you've been asked to develop a site and the client later introduces Ts&Cs that you'll breach whilst doing your job?

  - by Matt Lacey

  Disclaimer : this is all made up. Honest. And it represents no clients or employers living or dead, blah blah blah, etc. [Allegedly] As part of a website I've built, I've now been provided the Terms and Conditions of site usage to display on the site. These terms--which must be agreed to to access the site--include my (or any visitor to the sites) compliance with a number of clauses. Many of these clauses refer to general computer use and are not tied specifically to use of the site. Some of these clauses refer to things I have had to previously do as a legitimate part of my job and would expect to have to do again. When I've raised similar issues previously my line manager has said just to ignore it but that doesn't seem to be the professional thing to do. So, what do I do? Abiding by the terms would mean that I could no longer work on the project and would cause issues with my employer and the owner of the business the site is being created for. Ignoring them could lead to possible future issues with the business owner and is not something I'm necessarily happy with (the deliberate breaking of a legal contract). Neither option is one I'd choose and could have major consequences. Any thoughts?

• Conventions for search result scoring

  - by DeaconDesperado

  I assume this type of question is more on-topic here than on regular SO. I have been working on a search feature for my team's web application and have had a lot of success building a multithreaded, "divide and conquer" processing system to work through a large amount of fulltext. Our problem domain is pretty specific. Users of the app generate posts, and as a general rule, posts that are more recent are considered to be of greater relevance. Some of the data we are trying to extract from search is very specific (user's feelings about specific items or things) and we are using python nltk to do named-entity extraction to find interesting likely query terms. Essentially we look for descriptive adjective-noun pairs and generate a general picture of a user's expressed sentiment as a list of tokens. This search is intended as an internal tool for our team to draw out a local picture of sentiments like "soggy pizza." There's some machine learning in there too to do entity resolution on terms like "soggy" to all manner of adjectives expressing nastiness. My problem is I am at a loss for how to go about scoring these results. The text being searched is split up into tokens in a list, so my initial approach would be to normalize a float score between 0.0-1.0 generated off of how far into the list the terms appear and how often they are repeated (a later mention of the term being worth less, earlier more, greater frequency-greater score, etc.) A certain amount of weight could be given to the timestamp as well, though I am not certain how to calculate this. I am curious if anyone has had to solve a similar problem in a search relevance grading between appreciable metrics (frequency, term location/colocation, recency) and if there are and guidelines for how to weight each. I should mention as well that the final fallback procedure in the search is to pipe the query to Sphinx, which has its own scoring practices. Sphinx operates as the last resort in case our application specific processing can't find any eligible candidates.

• Can we use Google Earth images by applying our Unity3D mesh ?

  - by Jake M

  We are developing a commercial app for iOS and Android. The app will display development plans(architectural drawings) in a real world 3D environment. The app will work by creating a Unity3D mesh, applies a google earth image as the texture then draws out 3d lines(architectural drawings) over the Unity Mesh. Question: We are unsure if this is allowed under Google's terms and agreements? See quoted text below. In the bold text below its a little vague whether what we are doing(explained above) is violating their terms and agreements. What do you think? Does anyone know how we contact google to ask them? You may not mass download or use bulk feeds of any Content, including but not limited to extracting numerical latitude or longitude coordinates, geocoding, text-based directions, imagery, visible map data, or Places data (including business listings) for use in other applications. You also may not trace Google Maps or Earth as the basis for tracing your own maps or geographic materials. For full details, please read section 10.3.1 of the Maps/Earth API Terms of Service. Does anyone have any advice/experience dealing with this stuff?

• SharePoint 2010 – SQL Server has an unsupported version 10.0.2531.0

  - by Jeff Widmer

  I am trying to perform a database attach upgrade to SharePoint Foundation 2010. At this point I am trying to attach the content database to a Web application by using Windows Powershell: Mount-SPContentDatabase -Name <DatabaseName> -DatabaseServer <ServerName> -WebApplication <URL> [-Updateuserexperience] I am following the directions from this TechNet article: Attach databases and upgrade to SharePoint Foundation 2010.  When I go to mount the content database I am receiving this error: Mount-SPContentDatabase : Could not connect to [DATABASE_SERVER] using integrated security: SQL server at [DATABASE_SERVER] has an unsupported version 10.0.2531.0. Please refer to “http://go.microsoft.com/fwlink/?LinkId=165761” for information on the minimum required SQL Server versions and how to download them. At first this did not make sense because the default SharePoint Foundation 2010 website was running just fine.  But then I realized that the default SharePoint Foundation site runs off of SQL Server Express and that I had just installed SQL Server Web Edition (since the database is greater than 4GB) and restored the database to this version of SQL Server. Checking the documentation link above I see that SharePoint Server 2010 requires a 64-bit edition of SQL Server with the minimum required SQL Server versions as follows: SQL Server 2008 Express Edition Service Pack 1, version number 10.0.2531 SQL Server 2005 Service Pack 3 cumulative update package 3, version number 9.00.4220.00 SQL Server 2008 Service Pack 1 cumulative update package 2, version number 10.00.2714.00 The version of SQL Server 2008 Web Edition with Service Pack 1 (the version I installed on this machine) is 10.0.2531.0. SELECT @@VERSION: Microsoft SQL Server 2008 (SP1) - 10.0.2531.0 (X64)   Mar 29 2009 10:11:52   Copyright (c) 1988-2008 Microsoft Corporation  Web Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: ) (VM) But I had to read the article several times since the minimum version number for SQL Server Express is 10.0.2531.0.  At first I thought I was good with the version of SQL Server 2008 Web that I had installed, also 10.0.2531.0.  But then I read further to see that there is a cumulative update (hotfix) for SQL Server 2008 SP1 (NOT the Express edition) that is required for SharePoint 2010 and will bump the version number to 10.0.2714.00. So the solution was to install the Cumulative update package 2 for SQL Server 2008 Service Pack 1 on my SQL Server 2008 Web Edition to allow SharePoint 2010 to work with SQL Server 2008 (other than the SQL Server 2008 Express version). SELECT @@VERSION (After installing Cumulative update package 2): Microsoft SQL Server 2008 (SP1) - 10.0.2714.0 (X64)   May 14 2009 16:08:52   Copyright (c) 1988-2008 Microsoft Corporation  Web Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: ) (VM)

• Claims-based Identity Terminology

  - by kaleidoscope

  There are several terms commonly used to describe claims-based identity, and it is important to clearly define these terms. · Identity In terms of Access Control, the term identity will be used to refer to a set of claims made by a trusted issuer about the user. · Claim You can think of a claim as a bit of identity information, such as name, email address, age, and so on. The more claims your service receives, the more you’ll know about the user who is making the request. · Security Token The user delivers a set of claims to your service piggybacked along with his or her request. In a REST Web service, these claims are carried in the Authorization header of the HTTP(S) request. Regardless of how they arrive, claims must somehow be serialized, and this is managed by security tokens. A security token is a serialized set of claims that is signed by the issuing authority. · Issuing Authority & Identity Provider An issuing authority has two main features. The first and most obvious is that it issues security tokens. The second feature is the logic that determines which claims to issue. This is based on the user’s identity, the resource to which the request applies, and possibly other contextual data such as time of day. This type of logic is often referred to as policy[1]. There are many issuing authorities, including Windows Live ID, ADFS, PingFederate from Ping Identity (a product that exposes user identities from the Java world), Facebook Connect, and more. Their job is to validate some credential from the user and issue a token with an identifier for the user's account and  possibly other identity attributes. These types of authorities are called identity providers (sometimes shortened as IdP). It’s ultimately their responsibility to answer the question, “who are you?” and ensure that the user knows his or her password, is in possession of a smart card, knows the PIN code, has a matching retinal scan, and so on. · Security Token Service (STS) A security token service (STS) is a technical term for the Web interface in an issuing authority that allows clients to request and receive a security token according to interoperable protocols that are discussed in the following section. This term comes from the WS-Trust standard, and is often used in the literature to refer to an issuing authority. STS when used from developer point of view indicates the URL to use to request a token from an issuer.

• Asp.net session on browser close

  - by budugu

  Note: Cross posted from Vijay Kodali's Blog. Permalink How to capture logoff time when user closes browser? Or How to end user session when browser closed? These are some of the frequently asked questions in asp.net forums. In this post I'll show you how to do this when you're building an ASP.NET web application. Before we start, one fact: There is no full-proof technique to catch the browser close event for 100% of time. The trouble lies in the stateless nature of HTTP. The Web server is out of the picture as soon as it finishes sending the page content to the client. After that, all you can rely on is a client side script. Unfortunately, there is no reliable client side event for browser close. Solution: The first thing you need to do is create the web service. I've added web service and named it AsynchronousSave.asmx.    Make this web service accessible from Script, by setting class qualified with the ScriptServiceAttribute attribute...  Add a method (SaveLogOffTime) marked with [WebMethod] attribute. This method simply accepts UserId as a string variable and writes that value and logoff time to text file. But you can pass as many variables as required. You can then use this information for many purposes. To end user session, you can just call Session.Abandon() in the above web method. To enable web service to be called from page’s client side code, add script manager to page. Here i am adding to SessionTest.aspx page When the user closes the browser, onbeforeunload event fires on the client side. Our final step is adding a java script function to that event, which makes web service calls. The code is simple but effective My Code HTML:( SessionTest.aspx ) C#:( SessionTest.aspx.cs ) That’s’ it. Run the application and after browser close, open the text file to see the log off time. The above code works well in IE 7/8. If you have any questions, leave a comment.

• Sesame update du jour: SL 4, OOB, Azure, and proxy support

  - by Fabrice Marguerie

  I've just published a new version of Sesame Data Browser. Here's what's new this time: Upgraded to Silverlight 4 Can run out-of-browser (OOB), with elevated permissions. This gives you an icon on your desktop and enables new scenarios. Note: The application is unsigned for the moment. Support for Windows Azure authentication Support for SQL Azure authentication If you are behind a proxy that requires authentication, just give Sesame a new try after clicking on "If you are behind a proxy that requires authentication, please click here" An icon and a button for closing connections are now displayed on connection tabsSome less visible improvements Here is the connection view with anonymous access: If you want to access Windows Azure tables as OData, all you have to do is use your table storage endpoint as the URL, and provide your access key: A Windows Azure table storage address looks like this: http://<your account>.table.core.windows.net/ If you want to browse your SQL Azure databases with Sesame, you have to enable OData support for them at https://www.sqlazurelabs.com/ConfigOData.aspx. I won't show how it works because it's already been done in several places over the Web. Here are pointers: OData.org: Got SQL Azure? Then you've got OData OakLeaf Systems: Enabling and Using the OData Protocol with SQL Azure Patrick Verbruggen: Creating an OData feed for your Azure databases Shawn Wildermuth: SQL Azure's OData Support Jack Greenfield: How to Use OData for SQL Azure with AppFabric Access Control You can choose to enable anonymous access or not. When you don't enable anonymous access, you have to provide an Issuer name and a Secret key, and optionally an Security Token Service (STS) endpoint: Excerpt from Jack Greenfield's blog: To enable OData access to the currently selected database, check the box labeled "Enable OData". When OData access is enabled, database user mapping information is displayed at the bottom of the form.Use the drop down list labeled "Anonymous Access User" to select an anonymous access user. If an anonymous access user is selected, then all queries against the database presented without credentials will execute by impersonating that user. You can access the database as the anonymous user by clicking on the link provided at the bottom of the page. If no anonymous access user is selected, then the OData Service will not allow anonymous access to the database.Click the link labeled "Add User" to add a user for authenticated access. In the pop up panel, select the user from the drop down list. Leave the issuer name empty for simple authentication, or provide the name of a trusted Security Token Service (STS) for federated authentication. For example, to federate with another ACS based STS, provide the base URI for the STS endpoint displayed by the Windows Azure AppFabric Portal for the STS.Click the "OK" button to complete the configuration process and dismiss the pop up panel. When one or more authenticated access users are added, the OData Service will impersonate them when appropriate credentials are presented. You can designate as many authenticated access users as you like. The OData Service will decide which one to impersonate for each query by inspecting the credentials presented with the query.Next time I'll give an overview of how Sesame Data Browser is built.In the meantime, happy data browsing!

• Cloud Computing : publication du volet 3 du Syntec Numérique

  - by Eric Bezille

  Une vision client/fournisseur réunie autour d'une ébauche de cadre contractuel Lors de la Cloud Computing World Expo qui se tenait au CNIT la semaine dernière, j'ai assisté à la présentation du nouveau volet du Syntec numérique sur le Cloud Computing et les "nouveaux modèles" induits : modèles économiques, contrats, relations clients-fournisseurs, organisation de la DSI. L'originalité de ce livre blanc vis à vis de ceux déjà existants dans le domaine est de s'être attaché à regrouper l'ensemble des acteurs clients (au travers du CRIP) et fournisseurs, autour d'un cadre de formalisation contractuel, en s'appuyant sur le modèle e-SCM. Accélération du passage en fournisseur de Services et fin d'une IT en silos ? Si le Cloud Computing permet d'accélérer le passage de l'IT en fournisseur de services (dans la suite d'ITIL v3), il met également en exergue le challenge pour les DSI d'un modèle en rupture nécessitant des compétences transverses permettant de garantir les qualités attendues d'un service de Cloud Computing : déploiement en mode "self-service" à la demande, accès standardisé au travers du réseau,  gestion de groupes de ressources partagées,  service "élastique" : que l'on peut faire croitre ou diminuer rapidement en fonction de la demande mesurable On comprendra bien ici, que le Cloud Computing va bien au delà de la simple virtualisation de serveurs. Comme le décrit fort justement Constantin Gonzales dans son blog ("Three Enterprise Principles for Building Clouds"), l'important réside dans le respect du standard de l'interface d'accès au service. Ensuite, la façon dont il est réalisé (dans le nuage), est de la charge et de la responsabilité du fournisseur. A lui d'optimiser au mieux pour être compétitif, tout en garantissant les niveaux de services attendus. Pour le fournisseur de service, bien entendu, il faut maîtriser cette implémentation qui repose essentiellement sur l'intégration et l'automatisation des couches et composants nécessaires... dans la durée... avec la prise en charge des évolutions de chacun des éléments. Pour le client, il faut toujours s'assurer de la réversibilité de la solution au travers du respect des standards... Point également abordé dans le livre blanc du Syntec, qui rappelle les points d'attention et fait un état des lieux de l'avancement des standards autour du Cloud Computing. En vous souhaitant une bonne lecture...

• Oracle SOA Security for OUAF Web Services

  - by Anthony Shorten

  With the ability to use Oracle SOA Suite 11g with the Oracle Utilities Application Framework based products, an additional consideration needs to be configured to ensure correct integration. That additional consideration is security. By default, SOA Suite propagates any credentials from the calling application through to the interfacing applications. In most cases, this behavior is not appropriate as the calling application may use different credential stores and also some interfaces are “disconnected” from a calling application (for example, a file based load using the File Adapter). These situations require that the Web Service calls to the Oracle Utilities Application Framework based products have their own valid credentials. To do this the credentials must be attached at design time or at run time to provide the necessary credentials for the call. There are a number of techniques that can be used to do this: At design time, when integrating a Web Service from an Oracle Utilities Application Framework based product you can attach the security policy “oracle/wss_username_token_client_policy” in the composite.xml view. In this view select the Web Service you want to attach the policy to and right click to display the context menu and select “Configure WS Policies” and select the above policy from the list. If you are using SSL then you can use “oracle/wss_username_token_over_ssl_client_policy” instead. At design time, you can also specify the credential key (csf-key) associated with the above policy by selecting the policy and clicking “Edit Config Override Properties”. You name the key appropriately. Everytime the SOA components are deployed the credential configuration is also sent. You can also do this after deployment, or what I call at “runtime”, by specifying the policy and credential key in the Fusion Middleware Control. Refer to the Fusion Middleware Control documentation on how to do this. To complete the configuration you need to add a map and the key specified earlier to the credential store in the Oracle WebLogic instance used for Oracle SOA Suite. From Fusion Middleware Control, you do this by selecting the domain the SOA Suite is installed in a select “Credentials” from the context menu. You now need to add the credentials by adding the map “oracle.wsm.security” (the name is IMPORTANT) and creating a key with the necessary valid credentials. The example below added a key called “mdm.key”. The name I used is for example only. You can name the key anything you like as long as it corresponds to the key you specified in the design time component. Note: I used SYSUSER as an example credentials in the example, in real life you would use another credential as SYSUSER is not appropriate for production use. This key can be reused for other Oracle Utilities Application Framework Web Service integrations or you can use other keys for individual Web Service calls. Once the key is created and the SOA Suite components deployed the transactions should be able to be called as necessary. If you need to change the password for the credentials it can be done using the Fusion Middleware Control functionality.

• Issues with timed out downloads via TomCat?

  - by Ira Baxter

  We get, in our opinion, a lot of failed download attempts and want to understand why. We offer downloads via an email link (typical): http://www.semanticdesigns.com/deliverEval/<productname> This is processed by Tomcat on Linux via a jsp file, with the following code: response.addHeader( "Content-Disposition", "attachment; filename=" + fileTail ); response.addHeader( "Content-Type", "application/x-msdos-program" ); byte[] buf = new byte[8192]; int read; try { java.io.FileInputStream input = new java.io.FileInputStream( filename ); java.io.OutputStream o = response.getOutputStream(); while( ( read = input.read( buf, 0, 8192 ) ) != -1 ){ o.write( buf, 0, read ); } o.flush(); } catch( Exception e ){ util.fatalError( request.getRequestURI(), "Error sending file '" + filename + "' to client", e ); throw e; } We get a lot of reported errors (about 50% error rate): URI --- /deliverEval/download.jsp Code Message: Error sending file '/home/sd/ShippingMasters/DMS/Domains/C/GCC3/Tools/TestCoverage/SD_C~GCC3_TestCoverage.1.6.12.exe' to client Stack Trace ----------- null at org.apache.coyote.tomcat5.OutputBuffer.realWriteBytes(byte[], int, int) (Unknown Source) at org.apache.tomcat.util.buf.ByteChunk.append(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.OutputBuffer.writeBytes(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.OutputBuffer.write(byte[], int, int) (Unknown Source) at org.apache.coyote.tomcat5.CoyoteOutputStream.write(byte[], int, int) (Unknown Source) at org.apache.jsp.deliverEval.download_jsp._jspService(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at org.apache.jasper.runtime.HttpJspBase.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at javax.servlet.http.HttpServlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.jasper.servlet.JspServletWrapper.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, boolean) (Unknown Source) at org.apache.jasper.servlet.JspServlet.serviceJspFile(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.lang.String, java.lang.Throwable, boolean) (Unknown Source) at org.apache.jasper.servlet.JspServlet.service(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) (Unknown Source) at javax.servlet.http.HttpServlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse) (Unknown Source) at org.apache.catalina.core.StandardWrapperValve.invoke(org.apache.catalina.Request, org.apache.catalina.Response, org.apache.catalina.ValveContext) (Unknown Source) We don't understand why this rate should be so high. Is there any way to get more information about the cause of the error? It is useful to know that these are pretty big documents, 3-50 megabytes. They reside on the Linux server so reading them is just a local disk read, and is unlikely to be a contributor to the problem. But sheer size might be an issue for the recipients browser? Is this kind of error rate typical for downloads? My personal experience downloading other's documents suggests no; our internal attempts show this to be very reliable, but we're operating on our internal network for such experiments so we're missing the complexity of the intervening internet.

• Do you care about your Oracle System Support experience?

  - by user12244613

  It has been a while since I blogged about Systems Support within Oracle. I want to take this opportunity to raise awareness of how Oracle is communicating out to its systems customers. Previously every item to be communicated was sent independently via an email message however, not all messages appear to be being getting the attention they require. In an effort to ensure Oracle is reaching all of our Sun and Oracle System customers, we have created the Oracle Systems Support Newsletter. This monthly newsletter will have a summary of customer support relevant information for you to use and will cover topics that impact your support experience. For example: 1. Did you know that sending explorer content to email addresses with @sun.com is going away soon? For more information, review the Document 1362484.1 2. Are you an Auto Service Request (ASR) user? If yes, here are the latest changes: · ASR Manager accepts My Oracle Support User Name (email address) and password. [Doc ID 1345484.1] · ASR IP Address for secure file transfer has changed [Doc ID 1338575.1] · ASR No Heartbeat Status - Find out how to resolve [Doc ID 1346328.1] 3. Did you notice we have changed the Service Request options for Hardware and introduced a new problem category called “Automated Diagnosis”? This service streamlines the data you send in and then automatically provides an update of known issues found in your My Oracle Support Service Request. This feature also fast tracks hardware failures by sending parts as soon as the data is analyzed. Have you used this new feature? If yes tell us about it – take the 5minute survey 4. Are you being proactive or are you still ‘fire fighting’ in the reactive mode? If you are being proactive for your Oracle System products you might have used Oracle Sun System Analysis. Did you finding this helpful? Can we improve it? You tell us, take the 5minute survey 5. Are you aware that if you attach files to your Service Request it enables the support engineer to start work straight away? For a summary of products and files review the Newsletter. 6. Are you struggling to find patches or firmware or product downloads? If yes, these types of issues are all addressed in the Newsletter. If this is the type of information you want to know about each month, then take time to read the Newsletter link and bookmark it in My Oracle Support so you can stay informed. Thanks for your time.

• When following SRP, how should I deal with validating and saving entities?

  - by Kristof Claes

  I've been reading Clean Code and various online articles about SOLID lately, and the more I read about it, the more I feel like I don't know anything. Let's say I'm building a web application using ASP.NET MVC 3. Let's say I have a UsersController with a Create action like this: public class UsersController : Controller { public ActionResult Create(CreateUserViewModel viewModel) { } } In that action method I want to save a user to the database if the data that was entered is valid. Now, according to the Single Responsibility Principle an object should have a single responsibility, and that responsibility should be entirely encapsulated by the class. All its services should be narrowly aligned with that responsibility. Since validation and saving to the database are two separate responsibilities, I guess I should create to separate class to handle them like this: public class UsersController : Controller { private ICreateUserValidator validator; private IUserService service; public UsersController(ICreateUserValidator validator, IUserService service) { this.validator = validator; this.service= service; } public ActionResult Create(CreateUserViewModel viewModel) { ValidationResult result = validator.IsValid(viewModel); if (result.IsValid) { service.CreateUser(viewModel); return RedirectToAction("Index"); } else { foreach (var errorMessage in result.ErrorMessages) { ModelState.AddModelError(String.Empty, errorMessage); } return View(viewModel); } } } That makes some sense to me, but I'm not at all sure that this is the right way to handle things like this. It is for example entirely possible to pass an invalid instance of CreateUserViewModel to the IUserService class. I know I could use the built in DataAnnotations, but what when they aren't enough? Image that my ICreateUserValidator checks the database to see if there already is another user with the same name... Another option is to let the IUserService take care of the validation like this: public class UserService : IUserService { private ICreateUserValidator validator; public UserService(ICreateUserValidator validator) { this.validator = validator; } public ValidationResult CreateUser(CreateUserViewModel viewModel) { var result = validator.IsValid(viewModel); if (result.IsValid) { // Save the user } return result; } } But I feel I'm violating the Single Responsibility Principle here. How should I deal with something like this?

• When to use SOAP over REST

  So, how does REST based services differ from SOAP based services, and when should you use SOAP? Representational State Transfer (REST) implements the standard HTTP/HTTPS as an interface allowing clients to obtain access to resources based on requested URIs. An example of a URI may look like this http://mydomain.com/service/method?parameter=var1&parameter=var2. It is important to note that REST based services are stateless because http/https is natively stateless. One of the many benefits for implementing HTTP/HTTPS as an interface is can be found in caching. Caching can be done on a web service much like caching is done on requested web pages. Caching allows for reduced web server processing and increased response times because content is already processed and stored for immediate access. Typical actions performed by REST based services include generic CRUD (Create, Read, Update, and Delete) operations and operations that do not require state. Simple Object Access Protocol (SOAP) on the other hand uses a generic interface in order to transport messages. Unlike REST, SOAP can use HTTP/HTTPS, SMTP, JMS, or any other standard transport protocols. Furthermore, SOAP utilizes XML in the following ways: Define a message Defines how a message is to be processed Defines the encoding of a message Lays out procedure calls and responses As REST aligns more with a Resource View, SOAP aligns more with a Method View in that business logic is exposed as methods typically through SOAP web service because they can retain state. In addition, SOAP requests are not cached therefore every request will be processed by the server. As stated before Soap does retain state and this gives it a special advantage over REST for services that need to preform transactions where multiple calls to a service are need in order to complete a task. Additionally, SOAP is more ideal for enterprise level services that implement standard exchange formats in the form of contracts due to the fact that REST does not currently support this. A real world example of where SOAP is preferred over REST can be seen in the banking industry where money is transferred from one account to another. SOAP would allow a bank to perform a transaction on an account and if the transaction failed, SOAP would automatically retry the transaction ensuring that the request was completed. Unfortunately, with REST, failed service calls must be handled manually by the requesting application. References: Francia, S. (2010). SOAP vs. REST.
