  • Le W3C met à jour "Standards pour les Applications Web sur Mobile", un document qui fait l'état de l'art des spécifications

    Le W3C met à jour « Standards pour les Applications Web sur Mobile » Un document qui fait l'état de l'art des spécifications et leurs supports Ces dernières années, nous observons une progression nette des demandes de développements Web mobiles. Cela est dû au fait que de plus en plus d'utilisateurs optent pour des smartphones ou des tablettes pour accéder au Web via une multiplicité de navigateurs à maturités divergentes, véritable casse-tête pour le développeur.

  • AGPL License - does it apply in this scenario?

    - by user1645310
    There is an AGPLv3 based software (Client) that makes web service calls (using SOAP) to another software (Server - commercial, cloud based). There is no common code or any connection whatsoever between these two except for the web service calls being made. My questions - Does the Server need to be AGPL too? I guess not - but would like to confirm. Let us say the end point URL for the Server can be configured on the Client side (by editing an XML file) to connect it to different Servers (again, there is no connection other than the webservice calls being made) does it require any of these Servers being AGPL? Are there any issues in running the Client as a DLL that is loaded by other commercial applications on users' desktops? Does it require these other applications also to be AGPL?

  • Web Page Execution Internals

    - by octopusgrabbus
    My question is what is the subject area that covers web page execution/loading. I am looking to purchase a book by subject area that covers when things execute or load in a web page, whether it's straight html, html and Javascript, or a PHP page. Is that topic covered by a detailed html book, or should I expect to find information like that in a JavaScript of PHP book? I understand that PHP and Perl execute on the server and that Javascript is client side, and I know there is a lot of on-line documentation describing <html>, <head>, <body>, and so on. I'm just wondering what subject area a book would be in to cover all that, not a discussion of the best book or someone's favorite book, but the subject area.

  • Deploying Asp.net MVC web application [migrated]

    - by Pankaj Upadhyay
    I have been trying to find a neat tutorial, guide or step by step instructions for deploying an Asp.net MVC3 webapp but have found nothing so far. Everyone talks about his version of the stroy and different type of MVC versions. Right now, I have build a simple Asp.net MVC web application which i need to deploy on my shared hosting account. In a very simple manner, I need to know which files should i copy. Do i upload everything in my webproject directory to the server including the controller directory, views, models, content and bin directory ?. What about the Global.asax, web.config, packages.config, myapp.publish.xml. In short, I have no idea which files should be uploaded and which should be not. I am sure of one thing that i need few(MVC and Razor dlls) following dlls in bin directory. Just treat me as someone who has never deployed any website NOTE:- I don't have VS SP1 installed and it doesn't install either. Basically i need a manual procedure.

  • How should a JEE application store credentials for logging in to an external system?

    - by FGreg
    I am in a situation where I have a Web Application (WAR) that is accessing a REST service provided by another application. The REST service uses Basic HTTP Authentication. So that means the application calling the REST service needs to store user credentials somehow. To further complicate things, this is an enterprise, so there are different 'regions' the application moves through which will have different credentials for the same service (think local development, development region, integration region, user test region, production, etc...) My first instinct is that the credentials should be stored by the JEE container and the application should ask the container for the credentials (probably via JNDI?). I'm beginning to read about Java Authentication and Authorization Service (JAAS) but I'm not sure if that is the appropriate solution to this problem. How should a JEE application store credentials for logging in to an external system? A few more details about my WAR. It is a Spring-Integration project that has no front-end. The container I am working with is Websphere. I am using JEE 5 and Spring 4.0.1. To this point I have not needed to consider spring-security... does this situation mean I should re-evaluate that decision?

  • Why can't I expose an interface in a .NET asmx web service?

    - by mcliedtk
    I have a .NET web service (using asmx...have not upgraded to WCF yet) that exposes the following: public class WidgetVersion1 : IWidget {} public class WidgetVersion2 : IWidget {} When I attempt to bind to the web service, I get the following serialization error: Cannot serialize member WidgetVersion1 of type IWidget because it is an interface. I have tried adding various attributes to the IWidget interface (XmlIgnore, SoapIgnore, NonSerialized), but they are not valid on an interface. Does anyone know why I am unable to expose the interface? I assume WSDL does not support interfaces, but couldn't .NET get around this by simply not serializing the interface? Are there any ways around this apart from removing the IWidget interface from the WidgetVersion1 and WidgetVersion2 class definitions?

  • Google présente Chrome Web Store, son magasin d'applications a quelques similitudes avec celui d'App

    Google présente son Chrome Web Store, son magasin d'applications a quelques similitudes avec celui d'Apple La semaine dernière, Google a enchainé les annonces importantes lors de sa conférence de développement I/O. La firme semble mettre en place diverses nouveautés qui s'articulent autour de la sortie prochaine de son système d'exploitation Chrome OS. Vendredi a été présenté le Chrome Web Store, une boutique d'application qui commercialisera (ou offrira) des programmes pour les smartphones et terminaux mobiles utilisant Chrome ainsi que pour les ordinateurs équipés de Chrome OS (jeux, applications, plug-ins pour Chrome, etc.). A Mountain View, on semble donc vouloir fortement concurrence l'App Store. D'ailleurs, le...

  • Is ignoring clients data during an automatic upgrading acceptable?

    - by A competent translator
    I recently faced a deletion of my calendar and notes data inside a third party application ( Horde ) on my online space. When I told the web hosting provider they replied that they were doing an upgrade to system software (!!) and client third party applications are not within their reach or backup policy. They don't even have a backup of my data. Is this practice acceptable from a web hosting provider, even for an individual clients ? I know that backing up my data is my responsibility but I anticipated that backup copies done by the host would be available when needed.

  • Where to place web.xml outside WAR file for secure redirect?

    - by Silverhalide
    I am running Tomcat 7 and am deploying a bunch of applications delivered to me by a third party as WAR files. I'd like to force some of those apps to always use SSL. (All the "SSL" apps are in one service; other apps outside this discussion are in another service.) I've figured out how to use conf\web.xml to redirect apps from HTTP to HTTPS, but that applies to all applications hosted by Tomcat. I've also figured out how to put web.xml in an unpacked app's web-inf directory; that does the trick for that specific app, but runs the risk of being overwritten if our vendor gives us a new war file to deploy. I've also tried placing the web.xml file in various places under conf\service\host, or under appbase, but none seem to work. Is it possible to redirect some apps to SSL without forcing all apps to redirect, or to put the web.xml file inside the extracted WAR file? Here's my server.xml: <Service name="secure"> <Connector port="80" connectionTimeout="20000" redirectPort="443" URIEncoding="UTF-8" enableLookups="false" compression="on" protocol="org.apache.coyote.http11.Http11Protocol" compressableMimeType="text/html,text/xml,text/plain,text/javascript,application/json,text/css"/> <Connector port="443" URIEncoding="UTF-8" enableLookups="false" compression="on" protocol="org.apache.coyote.http11.Http11Protocol" compressableMimeType="text/html,text/xml,text/plain,text/javascript,application/json,text/css" scheme="https" secure="true" SSLEnabled="true" sslProtocol="TLS" keystoreFile="..." keystorePass="..." keystoreType="PKCS12" truststoreFile="..." truststorePass="..." truststoreType="JKS" clientAuth="false" ciphers="SSL_RSA_WITH_RC4_128_MD5,SSL_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_DSS_WITH_AES_128_CBC_SHA,SSL_RSA_WITH_AES_128_CBC_SHA"/> <Engine name="secure" defaultHost="localhost"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> <Host name="localhost" appBase="webapps" unpackWARs="false" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> </Host> </Engine> </Service> <Service name="mutual-secure"> ... </Service> The content of the web.xml files I'm playing with is: <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0" metadata-complete="true"> <security-constraint> <web-resource-collection> <web-resource-name>All applications</web-resource-name> <url-pattern>/*</url-pattern> </web-resource-collection> <user-data-constraint> <description>Redirect all requests to HTTPS</description> <transport-guarantee>CONFIDENTIAL</transport-guarantee> </user-data-constraint> </security-constraint> </web-app> (For conf\web.xml the security-constraint is added just before the end of the existing file, rather than create a new file.) My webapps directory (currently) contains only the WAR files.

  • HTG Explains: How Hackers Take Over Web Sites with SQL Injection / DDoS

    - by Jason Faulkner
    Even if you’ve only loosely followed the events of the hacker groups Anonymous and LulzSec, you’ve probably heard about web sites and services being hacked, like the infamous Sony hacks. Have you ever wondered how they do it? There are a number of tools and techniques that these groups use, and while we’re not trying to give you a manual to do this yourself, it’s useful to understand what’s going on. Two of the attacks you consistently hear about them using are “(Distributed) Denial of Service” (DDoS) and “SQL Injections” (SQLI). Here’s how they work.

  • Modelling in Agile Development

    - by bertzzie
    I'm writing a bachelor dissertation report where I'm developing a system with Agile methodology. Given that the development is an one man show, of course the "Agile" I did was not really agile at all (from my understanding at least). So I want some perspective from SO crowds, who is of course a professional, real world, developer with tons of experience. I think real world experience is better than the theory and experiments that I did. My question is: Do we model during development time when using Agile? UML? DFD? Or a Functional Specification is enough1? If modelling is not really necessary, what do we use to communicate to the user, as the user almost always won't understand UML or DFD? For my system, I use UI & UX Design with heavy prototyping, but then I don't have time to draw UML any more. Which one is better? 1 http://www.joelonsoftware.com/articles/fog0000000036.html I hope the question's not "subjective and argumentative" as I know this question exist because of my lack of understanding in the agile development. If it is, could someone just give me a pointer or reference about that? Possible duplicate: Do you use UML in Agile development practices?

  • How can Excel 2007 / 2010 consume a REST web service?

    - by jallen
    What options exist to consume a REST web service from within Excel 2007 / 2010? I can use XML Maps to consume a basic XML list, but that doesn't let me build a dynamic URL (so I could include parameters). For example, I can add an XML Map to Excel for http://machine/service/level/5 and display the values in the workbook just fine - no problem there. The real question is, how can I dynamically change the /5 part of the URL to come from another cell in excel? That way I can have a couple of cells that have the options (what ID, what name, etc.) and whenever those values change (ideally) a new dynamic URL would be constructed and the XML map would be refreshed. Is such a thing possible? Does anyone else have a better way to take some parameters, call a web service (REST or SOAP, I'm not picky) and shove the results back into excel for further manipulation?

  • Tips for Using Multiple Development Systems

    - by Tim Lytle
    When I travel, I don't pack up the desktop I use in the office and take it with me. Maybe I should, but I don't. However, since I'm a contract programmer I like to be able to work wherever I am: I'm mostly thinking of web development here. Version Control goes a long way in keeping sane and working on multiple projects on multiple systems (two or three computers); however, there are the issues of: IDE settings - different display sizes mean the IDE settings can't be completely synced, if at all. Database - if the database is 'external' (even if it's running on the same system, it's not in version control), how do you maintain the needed syncs of structure. Development Stack - Some projects need non-standard extensions, libraries, etc installed. Just an overview of some of the hassle involved with developing on multiple systems. I'll probably end up asking some specific questions, but I thought a CW style tips might reveal some things I would even think to ask about. Update: I guess this would also address tips to make upgrading/replacing your development system easier (something I've just done). So, one tip per answer please, so the 'top' tips are easy to find. How do you make it easier to develop on multiple systems, or to transfer work after upgrading/replaceing a development system?

  • Where to prepare (legal) "embeded" documents for the web [on hold]

    - by WHITECOLOR
    Say I have to have terms of use on site, a place the text as marked up html. Where it is better to prepare this document initially if it is going to placed to the web? Considering that such documents are prepared and changed by lawyers, it is not very applicable for them to use text editor. And it is not very efficient to manually process content to prepare it for the web as it is changed. For now my solution is: Prepare document text in google docs keeping some simple structure (title, ordered lit of features, simple paragraphs), save as html (it will contain some unnecessary markup) and then use custom conversion tool (some script) to convert saved html from google docs to simple html and inject new version to the site. What is common practiceses for this problem? What is the workflow of preparing and publishing such documents.

  • Is it possible to programmatically control c# health monitoring without using the web.config file?

    - by Adam
    I have developed my own custom provider for the health monitoring; however, I use parameters in the constructor and this is not allowed when using the health monitoring from the web.config file. Does anyone know if I can turn on/off the monitoring and have it watch properly through code (possibly in my global.asax file on application startup). Or, is it possible for me to create my own watcher that will do the same thing as the health monitor. Or, finally - can I just pass variables from the web.config setup (i'm not familiar with the public token part of the provider type declaration). Thanks in advance
