  • Building Visual Studio Setup Projects with TFS 2010 Team Build

    - by Jakob Ehn
    One of the most common complaints from people starting to use Team Build is that is doesn’t support building Microsoft’s own Setup and Deployment project (*.vdproj). When creating a default build definition that compiles a solution containing a setup project, you’ll get the following warning: The project file "MyProject.vdproj" is not supported by MSBuild and cannot be built.   This is what the problem is all about. MSBuild, that is used for compiling your projects, does not understand the proprietary vdproj format defined by Microsoft quite some time ago. Unfortunately there is no sign that this will change in the near future, in fact the setup projects has barely changed at all since they were introduced. VS 2010 brings no new features or improvements hen it comes to the setup projects. VS 2010 does include a limited version of InstallShield which promises to be more MSBuild friendly and with more or less the same features as VS setup projects. I hope to get a closer look at this installer project type soon. But, how do we go about to build a Visual Studio setup project and produce an MSI as part of a Team Build process? Well, since only one application known to man understands the vdproj projects, we will have to installa copy of Visual Studio on the build server. Sad but true. After doing this, we use the Visual Studio command line interface (devenv) to perform the build. In this post I will show how to do this by using the InvokeProcess activity directly in a build workflow template. You’ll want to run build your setup projects after you have successfully compiled the projects.   Install Visual Studio 2010 on the build server(s)   Open your build process template /remember to branch or copy the xaml file before modifying it!)   Locate the Try to Compile the Project activity   Drop an instance of the InvokeProcess activity from the toolbox onto the designer, after the Run MSBuild for Project activity   Drop an instance of the WriteBuildMessage activity inside the Handle Standard Output section. Set the Importance property to Microsoft.TeamFoundation.Build.Client.BuildMessageImportance.High (NB: This is necessary if you want the output from devenv to show up in the build log when running the build with the default verbosity) Set the Message property to stdOutput   Drop an instance of the WriteBuildError activity to the Handle Error Output section Set the Message property to errOutput   Select the InvokeProcess activity and set the values of the parameters to:     The finished workflow should look like this:     This will generate the MSI files, but they won’t be copied to the drop location. This is because we are using devenv and not MSBuild, so we have to do this explicitly   Drop a Sequence activity somewhere after the Copy to Drop location activity.   Create a variable in the Sequence activity of type IEnumerable<String> and call it GeneratedInstallers   Drop a FindMatchingFiles activity in the sequence activity and set the properties to:     Drop a ForEach<String> activity after the FindMatchingFiles activity. Set the Value property to GeneratedInstallers   Drop an InvokeProcess activity inside the ForEach activity.  FileName: “xcopy.exe” Arguments: String.Format("""{0}"" ""{1}""", item, BuildDetail.DropLocation) The Sequence activity should look like this:     Save the build process template and check it in.   Run the build and verify that the MSI’s is built and copied to the drop location.   Note 1: One of the drawback of using devenv like this in a team build is that since all the output from the default compilations is placed in the Binaries folder, the outputs is not avaialable when devenv is invoked, which causes the whole solution to rebuild again. In TFS 2008, this was pretty simple to fix by using the CustomizableOutDir property. In TFS 2010, the same feature is not avaialble. Jim Lamb blogged about this recently, have a look at it if you have a problem with this: http://blogs.msdn.com/jimlamb/archive/2010/04/13/customizableoutdir-in-tfs-2010.aspx   Note 2: Although the above solution works, a better approach is to wrap this in a custom activity that you can use in your builds. I will come back to this in a future post.

  • Oracle’s New Approach to Cloud-based Applications User Experiences

    - by Oracle OpenWorld Blog Team
    By Misha Vaughan It was an exciting Oracle OpenWorld this year for customers and partners, as they got to see what their input into the Oracle user experience research and development process has produced for cloud-delivered applications. The result of all this engagement and listening is a focus on simplicity, mobility, and extensibility. These were the core themes across Oracle OpenWorld sessions, executive roundtables, and analyst briefings given by Jeremy Ashley, Oracle's vice president of user experience. The highlight of every meeting with a customer featured the new simplified UI for Oracle’s cloud applications.    Attendees at some sessions and events also saw a vision of what is coming next in the Oracle user experience, and they gave direct feedback on whether this would help solve their business problems.  What did attendees think of what they saw this year? Rebecca Wettemann of Nucleus Research was part of  an analyst briefing on next-generation user experiences from Oracle. Here’s what she told CRM Buyer in an interview just after the event:  “Many of the improvements are incremental, which is not surprising, as Oracle regularly updates its application,” Rebecca Wettemann, vice president of Nucleus Research, told CRM Buyer. "Still, there are distinct themes to this latest set of changes. One is usability. Oracle Sales Cloud, for example, is designed to have zero training for onboarding sales reps, which it does," she explained. "It is quite impressive, actually—the intuitive nature of the application and the design work they have done with this goal in mind. The software uses as few buttons and fields as possible," she pointed out. "The sales rep doesn't have to ask, 'what is the next step?' because she can see what it is."  What else did we hear? Oracle OpenWorld is a time when we can take a broader pulse of our customers’ and partners’ concerns. This year we heard some common user experience themes on the following: · A desire to continue to simplify widely used self-service tasks · A need to understand how customers or partners could take some of the UX lessons learned on simplicity and mobility into their own custom areas and projects  · The continuing challenge of needing to support bring-your-own-device and corporate-provided mobile devices to end users · A desire to harmonize user experiences across platforms for specific business-use cases  What does this mean for next year? Well, there were a lot of things we could only show to smaller groups of customers in our Oracle OpenWorld usability labs and HQ lab tours, to partners at our Expo, and to analysts under non-disclosure agreements. But we used these events as a way to get some early feedback about where we are focusing for the year ahead. Attendees gave us a positive response: @bkhan Saw some excellent UX innovations at the expo “@usableapps: Great job @mishavaughan and @vinoskey on #oow13 UX partner expo!” @WarnerTim @usableapps @mishavaughan @vinoskey @ultan Thanks for an interesting afternoon definitely liked the UX tool kits for partners. You can expect Oracle to continue pushing themes of simplicity, mobility, and extensibility even more aggressively in the next year.  If you are interested to find out what really goes on in the UX labs, such as what we are doing with smartphones, tablets, heads-up displays, and the AppsLab robots, feel free to reach out to me for more information: Misha Vaughan or on Twitter: @mishavaughan.

  • Best way to use GIT to maintain web application template

    - by Darren
    I am a sole developer and I have a web application template that I have created in Visual Studio. I am using GIT for source control, but only on my development machine. Presently I have a master and I create branches for new features, merging them back in to the master as I complete the features. I am at a point now where I am ready to use the template for deployments, and of course I want to continue adding new features via branching/merging. My question is: what would be the typical/recommended way for me to create application deployments based on the master? Should I clone the repository into a new directory that is for a particular web application? Or should I also use branching to do project development based on the main project? The projects would never be merged back into the master. However, it would be nice if I could merge future features into the master and have the ability to incorporate them into previously completed projects if desired. For more specific details of my environment: I am using TortoiseGIT in Windows 7, Visual Studio 2012, ASP.NET Web Pages. Obviously the main differences between deployments would simply be differing pages, CSS files and jQuery scripts. I found this post as I was writing this one. In order to do this should I clone the master repository and checkout from it?

  • Deploying Oracle ADF Essentials Applications to Glassfish

    - by Shay Shmeltzer
    With the new Oracle ADF Essentials offering you can now deploy applications that leverage Oracle ADF on the open source Glassfish 3.1 server. Deployment is documented in the official JDeveloper and ADF documentation (here) but below is a summary of the steps and a video of the steps you'll need to take to get a basic Oracle ADF Essentials application to work on GlassFish. Note - to make starting/stopping GlassFish easier for my demo I used my GlassFish extension that you can get here. First we'll install some ADF Runtime libraries on GlassFish Download and install Glassfish (Note - if you also have an Oracle DB on the same machine, you'll want to switch GlassFish's HTTP port to something else instead of 8080). Download the Oracle ADF Essentials packaging - this will get you an adf_essentials.zip file. Copy the adf_essentials.zip to the lib directory of your Glassfish domain - on a default windows install this would be: C:\glassfish3\glassfish\domains\domain1\lib Go the the above lib directory and issue a unzip -j adf_essentials.zip This will extract the ADF libraries to the directory. Now you can start the Glassfish server. Now let's configure Glassfish to handle applications of the ADF type: Invoke the admin console of glassfish (http://localhost:4848) and log into your admin account. Go to Configurations->Server-config->JVM Settings and choose the JVM Options tab Add the following entries: -XX:MaxPermSize=512m (note this entry should already exist so just make sure it has a big enough value) -Doracle.mds.cache=simple While we are in the admin console, we can also define JDBC connections that will be used by our application. Go into Resources->JDBC->JDBC Connection Pools and click to create a New one Give it a name and choose the resource type to be javax.sql.XADataSource and choose Oracle as the Database Driver vendor. Click Next Scroll down to the Additional Properties section and start filling in the information for your database. The values for an Oracle XE will be (user=hr, databaseName = XE, Password=hr, ServerName=localhost, DriverType=thin, PortNumber=1521) Click Finish Click Ping to check your connection works. Now define a new JDBC Resource that will use the pool you just defined. In my example I called the resource jdbc/HRDS You will need this name to match the name in your Application Module connection configuraiton.Now you can re-start the Glassfish server for the changes to take effect. Get an ADF application going (you can use the regular Fusion Application template for this) Go into the project properties of your viewController project, under the deployment section click to edit the deployment profile that is defined there. Go to Platform and choose Glassfish 3.1 from the drop down list. Click ok to go back to your project. Go to Application -> Application Properties-> Deployment Go to Platform and choose Glassfish 3.1 from the drop down list. Click ok to go back to your project. This step will make sure that JDeveloper will autoamtically add the necessary ADF libraries to the EAR file that is being generated for deployment on Glassfish  Go to your Application->Deploy and deploy either to an EAR file or directly to a Glassfish server connection that you created. Things should just work, but if they don't then look up the server.log in the log directory and check out what error is in there. Here is a video demo of the various steps: Note - right now the deployment of an ADF application takes about 2 minutes on my machine we are hoping to be able to improve this timing in the future. People who are more familiar with Glassfish might want to explore using exploded directory deployment and see if they can get it to work.

  • What are all things that do/can happen when a user enters in a web page's URL?

    - by Job
    Sorry if this is a naive title. I am trying to break into web development, which is so far a foreign world to me. I have taken a basic intro to OS, intro to Networking as part of my bachelors degree several years ago. I cannot say that we went into things deeply, beyond academic assignments. I would like to understand things much better regarding to this specific task (e.g what goes on in at the OS level, at networking level, what are other computers involved, where do proxy servers and hackers come in). Again, at the very basic level this has been covered, but I would like to review this specific thing better. Are there chapter(s) os a specific book, or specific SHORT reading that you recommend? I have nothing against your list of 20 favorite books, but I want to understand this one thing better in 2-3 weeks of reading after work / on the weekends (realistically 5-10 hrs per week, so I am looking for about 15-20 hrs of reading material, NO MORE). I am not a fast reader :) Thanks.

  • How can I debug solutions in Visual Studio 2010 from a network share?

    - by alastairs
    I've recently got a new Mac laptop and am running VS2010 in a Parallels virtual machine. It's mostly working out well for me, but I'm having some problems with debugging specific project types, related to the fact that the projects are being accessed via a network share. Test projects don't run because the test runner can't load the tests' DLL. Web projects fail to run in the Visual Studio mini web server, throwing the following exception: 'An error occurred loading a configuration file: Failed to start monitoring changes to path\to\web.config'. I've spent the evening trawling the web with little luck on this. After reading these two posts, I tried out the usual CasPol changes, but then found this post from one of the early VS2010 betas indicating that CasPol is no longer needed/supported in .NET 4.0 and VS2010. The network share is accessible via both a mapped drive and the UNC path. The virtual machine runs its applications under the administrator account, which appears to have all the necessary permissions on the network share to create, read, write and delete files and folders. I say "appears to have" as I can't view the Security Properties of the appropriate folder via Explorer: the Security tab just isn't present. Has anyone managed to successfully load and debug web and test projects from a network share in VS2010?

  • How to configure IIS for SVG and web testing with Visual Studio?

    - by macias
    Let's say I have a simple web page with svg image in it: <img src="foobar.svg" alt="not working" /> If I make this page as static html page and view it directly svg is displayed. If I type the address of this svg -- it is displayed. But when I make this as .aspx page and launch it dynamically from Visual Studio I get alt text. If I type the address of this svg (from localhost, not as a local file) -- browser tries to download it instead of displaying. I already defined mime type in IIS (for entire server -- "image/svg+xml") and restarted IIS. Same effect as before. Question: what should I do more? Update WireShark won't work (it is in documentation), I tried also RawCap, but it cannot trace my connection (odd), luckily Fiddler worked: From client: GET http://127.0.0.1:1731/svg/document_edit.svg HTTP/1.1 Host: 127.0.0.1:1731 User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Answer from server: HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Thu, 16 Feb 2012 11:14:38 GMT X-AspNet-Version: 4.0.30319 Cache-Control: private Content-Type: application/octet-stream Content-Length: 87924 Connection: Close <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!-- Created with Inkscape (http://www.inkscape.org/) --> <svg xmlns: *** FIDDLER: RawDisplay truncated at 128 characters.

  • Single Sign On with 3 applications

    - by John H.
    I'm building three web applications in .NET that will all share a users database and login information. Lets pretend that application 1 is the "parent" application and applications "A" and "B" are the "child" applications. All users have to be logged into application 1 to have access to applications A and B. Authorization, Authentication, and MachineKey sections of all web configs are present and work correctly. I have the correct web.config settings in all applications to achieve Single Sign On except one problem remains: what do I put in the "loginUrl" attribute of the forms tag in Applications A and B. Assume that the url for the login to application 1 is "www.johnsapp.com/login.aspx" How can I get applications A and B to send the user back to application 1 for authentication using only settings in web.config?

  • Blend for Visual Studio 2013 Prototyping Applications with SketchFlow

    - by T
    Originally posted on: http://geekswithblogs.net/tburger/archive/2014/08/10/blend-for-visual-studio-2013-prototyping-applications-with-sketchflow.aspxSketchFlow enables rapid creating of dynamic interface mockups very quickly. The SketchFlow workspace is the same as the standard Blend workspace with the inclusion of three panels: the SketchFlow Feedback panel, the SketchFlow Animation panel and the SketchFlow Map panel. By using SketchFlow to prototype, you can get feedback early in the process. It helps to surface possible issues, lower development iterations, and increase stakeholder buy in. SketchFlow prototypes not only provide an initial look but also provide a way to add additional ideas and input and make sure the team is on track prior to investing in complete development. When you have completed the prototyping, you can discard the prototype and just use the lessons learned to design the application from or extract individual elements from your prototype and include them in the application. I don’t recommend trying to transition the entire project into a development project. Objects that you add with the SketchFlow style have a hand-sketched look. The sketch style is used to remind stakeholders that this is a prototype. This encourages them to focus on the flow and functionality without getting distracted by design details. The sketchflow assets are under sketchflow in the asset panel and are identifiable by the postfix “–Sketch”. For example “Button-Sketch”. You can mix sketch and standard controls in your interface, if required. Be creative, if there is a missing control or your interface has a different look and feel than the out of the box one, reuse other sketch controls to mimic the functionality or look and feel. Only use standard controls if it doesn’t distract from the idea that this is a prototype and not a standard application. The SketchFlow Map panel provides information about the structure of your application. To create a new screen in your prototype: Right-click the map surface and choose “Create a Connected Screen”. Name the screens with names that are meaningful to the stakeholders. The start screen is the one that has the green arrow. To change the start screen, right click on any other screen and set to start screen. Only one screen can be the start screen at a time. Rounded screen are component screens to mimic reusable custom controls that will be built into the final application. You can change the colors of all of the boxes and should use colors to create functional groupings. The groupings can be identified in the SketchFlow Project Settings. To add connections between screens in the SketchFlow Map panel. Move the mouse over a screen in the SketchFlow and a menu will appear at the bottom of the screen node. In the menu, click Connect to an existing screen. Drag the arrow to another screen on the Map. You add navigation to your prototype by adding connections on the SketchFlow map or by adding navigation directly to items on your interface. To add navigation from objects on the artboard, right click the item then from the menu, choose “Navigate to”. This will expose a sub-menu with available screens, backward, or forward. When the map has connected screens, the SketchFlow Player displays the connected screens on the Navigate sidebar. All screens show in the SketchFlow Player Map. To see the SketchFlow Player, run your SketchFlow prototype. The Navigation sidebar is meant to show the desired user work flow. The map can be used to view the different screens regardless of suggested navigation in the navigation bar. The map is able to be hidden and shown. As mentioned, a component screen is a shared screen that is used in more than one screen and generally represents what will be a custom object in the application. To create a component screen, you can create a screen, right click on it in the SketchFlow Map and choose “Make into component screen”. You can mouse over a screen and from the menu that appears underneath, choose create and insert component screen. To use an existing screen, select if from the Asset panel under SketchFlow, Components. You can use Storyboards and Visual State animations in your SketchFlow project. However, SketchFlow also offers its own animation technique that is simpler and better suited for prototyping. The SketchFlow Animation panel is above your artboard by default. In SketchFlow animation, you create frames and then position the elements on your interface for each frame. You then specify elapsed time and any effects you want to apply to the transition. The + at the top is what creates new frames. Once you have a new Frame, select it and change the property you want to animate. In the example above, I changed the Text of the result box. You can adjust the time between frames in the lower area between the frames. The easing and effects functions are changed in the center between each frame. You edit the hold time for frames by clicking the clock icon in the lower left and the hold time will appear on each frame and can be edited. The FluidLayout icon (also located in the lower left) will create smooth transitions. Next to the FluidLayout icon is the name of that Animation. You can rename the animation by clicking on it and editing the name. The down arrow chevrons next to the name allow you to view the list of all animations in this prototype and select them for editing. To add the animation to the interface object (such as a button to start the animation), select the PlaySketchFlowAnimationAction from the SketchFlow behaviors in the Assets menu and drag it to an object on your interface. With the PlaySketchFlowAnimationAction that you just added selected in the Objects and Timeline, edit the properties to change the EventName to the event you want and choose the SketchFlowAnimation you want from the drop down list. You may want to add additional information to your screens that isn’t really part of the prototype but is relevant information or a request for clarification or feedback from the reviewer. You do this with annotations or notes. Both appear on the user interface, however, annotations can be switched on or off at design and review time. Notes cannot be switched off. To add an Annotation, chose the Create Annotation from the Tools menu. The annotation appears on the UI where you will add the notes. To display or Hide annotations, click the annotation toggle at the bottom right on the artboard . After to toggle annotations on, the identifier of the person who created them appears on the artboard and you must click that to expand the notes. To add a note to the artboard, simply select the Note-Sketch from Assets ->SketchFlow ->Styles ->Sketch Styles. Drag and drop it to the artboard and place where you want it. When you are ready for users to review the prototype, you have a few options available. Click File -> Export and choose one of the options from the list: Publish to Sharepoint, Package SketchFlowProject, Export to Microsoft Word, or Export as Images. I suggest you play with as many of the options as you can to see what they do. Both the Sharepoint and Packaged SketchFlowProject allow you to collect feedback from one or more users that you can import into the project. The user can make notes on the UI and in the Feedback area in the bottom left corner of the player. When the user is done adding feedback, it is exported from the right most folder icon in the My Feedback panel. Feeback is imported on a panel named SketchFlow Feedback. To get that panel to show up, select Window -> SketchFlow Feedback. Once you have the panel showing, click the + in the upper right of the panel and find the notes you exported. When imported, they will show up in a list and on the artboard. To document your prototype, use the Export to Microsoft Word option from the File menu. That should get you started with prototyping.

  • WebSocket Applications using Java: JSR 356 Early Draft Now Available (TOTD #183)

    - by arungupta
    WebSocket provide a full-duplex and bi-directional communication protocol over a single TCP connection. JSR 356 is defining a standard API for creating WebSocket applications in the Java EE 7 Platform. This Tip Of The Day (TOTD) will provide an introduction to WebSocket and how the JSR is evolving to support the programming model. First, a little primer on WebSocket! WebSocket is a combination of IETF RFC 6455 Protocol and W3C JavaScript API (still a Candidate Recommendation). The protocol defines an opening handshake and data transfer. The API enables Web pages to use the WebSocket protocol for two-way communication with the remote host. Unlike HTTP, there is no need to create a new TCP connection and send a chock-full of headers for every message exchange between client and server. The WebSocket protocol defines basic message framing, layered over TCP. Once the initial handshake happens using HTTP Upgrade, the client and server can send messages to each other, independent from the other. There are no pre-defined message exchange patterns of request/response or one-way between client and and server. These need to be explicitly defined over the basic protocol. The communication between client and server is pretty symmetric but there are two differences: A client initiates a connection to a server that is listening for a WebSocket request. A client connects to one server using a URI. A server may listen to requests from multiple clients on the same URI. Other than these two difference, the client and server behave symmetrically after the opening handshake. In that sense, they are considered as "peers". After a successful handshake, clients and servers transfer data back and forth in conceptual units referred as "messages". On the wire, a message is composed of one or more frames. Application frames carry payload intended for the application and can be text or binary data. Control frames carry data intended for protocol-level signaling. Now lets talk about the JSR! The Java API for WebSocket is worked upon as JSR 356 in the Java Community Process. This will define a standard API for building WebSocket applications. This JSR will provide support for: Creating WebSocket Java components to handle bi-directional WebSocket conversations Initiating and intercepting WebSocket events Creation and consumption of WebSocket text and binary messages The ability to define WebSocket protocols and content models for an application Configuration and management of WebSocket sessions, like timeouts, retries, cookies, connection pooling Specification of how WebSocket application will work within the Java EE security model Tyrus is the Reference Implementation for JSR 356 and is already integrated in GlassFish 4.0 Promoted Builds. And finally some code! The API allows to create WebSocket endpoints using annotations and interface. This TOTD will show a simple sample using annotations. A subsequent blog will show more advanced samples. A POJO can be converted to a WebSocket endpoint by specifying @WebSocketEndpoint and @WebSocketMessage. @WebSocketEndpoint(path="/hello")public class HelloBean {     @WebSocketMessage    public String sayHello(String name) {         return "Hello " + name + "!";     }} @WebSocketEndpoint marks this class as a WebSocket endpoint listening at URI defined by the path attribute. The @WebSocketMessage identifies the method that will receive the incoming WebSocket message. This first method parameter is injected with payload of the incoming message. In this case it is assumed that the payload is text-based. It can also be of the type byte[] in case the payload is binary. A custom object may be specified if decoders attribute is specified in the @WebSocketEndpoint. This attribute will provide a list of classes that define how a custom object can be decoded. This method can also take an optional Session parameter. This is injected by the runtime and capture a conversation between two endpoints. The return type of the method can be String, byte[] or a custom object. The encoders attribute on @WebSocketEndpoint need to define how a custom object can be encoded. The client side is an index.jsp with embedded JavaScript. The JSP body looks like: <div style="text-align: center;"> <form action="">     <input onclick="say_hello()" value="Say Hello" type="button">         <input id="nameField" name="name" value="WebSocket" type="text"><br>    </form> </div> <div id="output"></div> The code is relatively straight forward. It has an HTML form with a button that invokes say_hello() method and a text field named nameField. A div placeholder is available for displaying the output. Now, lets take a look at some JavaScript code: <script language="javascript" type="text/javascript"> var wsUri = "ws://localhost:8080/HelloWebSocket/hello";     var websocket = new WebSocket(wsUri);     websocket.onopen = function(evt) { onOpen(evt) };     websocket.onmessage = function(evt) { onMessage(evt) };     websocket.onerror = function(evt) { onError(evt) };     function init() {         output = document.getElementById("output");     }     function say_hello() {      websocket.send(nameField.value);         writeToScreen("SENT: " + nameField.value);     } This application is deployed as "HelloWebSocket.war" (download here) on GlassFish 4.0 promoted build 57. So the WebSocket endpoint is listening at "ws://localhost:8080/HelloWebSocket/hello". A new WebSocket connection is initiated by specifying the URI to connect to. The JavaScript API defines callback methods that are invoked when the connection is opened (onOpen), closed (onClose), error received (onError), or a message from the endpoint is received (onMessage). The client API has several send methods that transmit data over the connection. This particular script sends text data in the say_hello method using nameField's value from the HTML shown earlier. Each click on the button sends the textbox content to the endpoint over a WebSocket connection and receives a response based upon implementation in the sayHello method shown above. How to test this out ? Download the entire source project here or just the WAR file. Download GlassFish4.0 build 57 or later and unzip. Start GlassFish as "asadmin start-domain". Deploy the WAR file as "asadmin deploy HelloWebSocket.war". Access the application at http://localhost:8080/HelloWebSocket/index.jsp. After clicking on "Say Hello" button, the output would look like: Here are some references for you: WebSocket - Protocol and JavaScript API JSR 356: Java API for WebSocket - Specification (Early Draft) and Implementation (already integrated in GlassFish 4 promoted builds) Subsequent blogs will discuss the following topics (not necessary in that order) ...

  • C++ Development Cinder/Visual Studio

    - by jayReegs
    I'm currently taking a Data Structures course that involves the development of C++ applications using microsoft visual studio express c++, an application called Cinder, and we turn in assignments via GitHub. I know Mac users in the class use X code to develop to our needs although some small issues arise with compilation that needs some debug work to be done. Windows just isn't cutting it for me anymore...I've welcomed myself to the darkside...I'm wondering if Linux distros have any development tools that would be compatible to create and run these types of applications?

  • How do I add a header to a VB.NET 2008 SOAP request? [migrated]

    - by robokev
    I have a VB.NET 2008 program that accesses a Siebel web service defined by a WSDL and using the SOAP protocol. The Siebel web service requires that a header containing the username, password and session type be included with the service request, but the header is not defined in the WSDL. So, when I test the WSDL using the soapUI utility, the request as defined by the WSDL looks like this: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:lov="http://www.siebel.com/xml/LOVService" xmlns:lis="http://www.siebel.com/xml/ListQuery"> <soapenv:Header/> <soapenv:Body> <lov:EAILOVGetListOfValues_Input> <lis:ListsQuery> <lis:ListQuery> <lis:Active>Y</lis:Active> <lis:LanguageCode>ENU</lis:LanguageCode> <lis:Type>CUT_ACCOUNT_TYPE</lis:Type> </lis:ListQuery> </lis:ListsQuery> </lov:EAILOVGetListOfValues_Input> </soapenv:Body> </soapenv:Envelope> But the above does not work because it contains an empty header that is missing user and session credentials. It only works if I manually replace <soapenv:Header/> with a header containing the username, password, and session type as follows: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:lov="http://www.siebel.com/xml/LOVService" xmlns:lis="http://www.siebel.com/xml/ListQuery"> <soapenv:Header> <UsernameToken xmlns="http://siebel.com/webservices">TESTUSER</UsernameToken> <PasswordText xmlns="http://siebel.com/webservices">TESTPASSWORD</PasswordText> <SessionType xmlns="http://siebel.com/webservices">None</SessionType> </soapenv:Header> <soapenv:Body> <lov:EAILOVGetListOfValues_Input> <lis:ListsQuery> <lis:ListQuery> <lis:Active>Y</lis:Active> <lis:LanguageCode>ENU</lis:LanguageCode> <lis:Type>CUT_ACCOUNT_TYPE</lis:Type> </lis:ListQuery> </lis:ListsQuery> </lov:EAILOVGetListOfValues_Input> </soapenv:Body> </soapenv:Envelope> My problem is that I cannot sort out how to translate the above into VB.NET 2008 code. I have no problem importing the WSDL into Visual Studio 2008, defining the service in VB code and referencing the web service methods. However, I cannot sort out how to define the web service in VB such that the updated header in included in the web service request instead of the empty header. Consequently all my service requests from VB fail. I can define a class that inherits from the SoapHeader class... Public Class MySoapHeader : Inherits System.Web.Services.Protocols.SoapHeader Public Username As String Public Password As String Public SessionType As String End Class ...but how do I include this header in the SOAP request made from VB?

  • User roles in GWT applications

    - by csaffi
    Hi everybody, I'm wondering if you could suggest me any way to implement "user roles" in GWT applications. I would like to implement a GWT application where users log in and are assigned "roles". Based on their role, they would be able to see and use different application areas. Here are two possible solution I thought: 1) A possible solution could be to make an RPC call to the server during onModuleLoad. This RPC call would generate the necessary Widgets and/or place them on a panel and then return this panel to the client end. 2) Another possible solution could be to make an RPC call on login retrieving from server users roles and inspecting them to see what the user can do. What do you think about? Thank you very much in advance for your help!

  • Getting a Web Resource Url in non WebForms Applications

    - by Rick Strahl
    WebResources in ASP.NET are pretty useful feature. WebResources are resources that are embedded into a .NET assembly and can be loaded from the assembly via a special resource URL. WebForms includes a method on the ClientScriptManager (Page.ClientScript) and the ScriptManager object to retrieve URLs to these resources. For example you can do: ClientScript.GetWebResourceUrl(typeof(ControlResources), ControlResources.JQUERY_SCRIPT_RESOURCE); GetWebResourceUrl requires a type (which is used for the assembly lookup in which to find the resource) and the resource id to lookup. GetWebResourceUrl() then returns a nasty old long URL like this: WebResource.axd?d=-b6oWzgbpGb8uTaHDrCMv59VSmGhilZP5_T_B8anpGx7X-PmW_1eu1KoHDvox-XHqA1EEb-Tl2YAP3bBeebGN65tv-7-yAimtG4ZnoWH633pExpJor8Qp1aKbk-KQWSoNfRC7rQJHXVP4tC0reYzVw2&t=634533278261362212 While lately excessive resource usage has been frowned upon especially by MVC developers who tend to opt for content distributed as files, I still think that Web Resources have their place even in non-WebForms applications. Also if you have existing assemblies that include resources like scripts and common image links it sure would be nice to access them from non-WebForms pages like MVC views or even in plain old Razor Web Pages. Where's my Page object Dude? Unfortunately natively ASP.NET doesn't have a mechanism for retrieving WebResource Urls outside of the WebForms engine. It's a feature that's specifically baked into WebForms and that relies specifically on the Page HttpHandler implementation. Both Page.ClientScript (obviously) and ScriptManager rely on a hosting Page object in order to work and the various methods off these objects require control instances passed. The reason for this is that the script managers can inject scripts and links into Page content (think RegisterXXXX methods) and for that a Page instance is required. However, for many other methods - like GetWebResourceUrl() - that simply return resources or resource links the Page reference is really irrelevant. While there's a separate ClientScriptManager class, it's marked as sealed and doesn't have any public constructors so you can't create your own instance (without Reflection). Even if it did the internal constructor it does have requires a Page reference. No good… So, can we get access to a WebResourceUrl generically without running in a WebForms Page instance? We just have to create a Page instance ourselves and use it internally. There's nothing intrinsic about the use of the Page class in ClientScript, at least for retrieving resources and resource Urls so it's easy to create an instance of a Page for example in a static method. For our needs of retrieving ResourceUrls or even actually retrieving script resources we can use a canned, non-configured Page instance we create on our own. The following works just fine: public static string GetWebResourceUrl(Type type, string resource ) { Page page = new Page(); return page.ClientScript.GetWebResourceUrl(type, resource); } A slight optimization for this might be to cache the created Page instance. Page tends to be a pretty heavy object to create each time a URL is required so you might want to cache the instance: public class WebUtils { private static Page CachedPage { get { if (_CachedPage == null) _CachedPage = new Page(); return _CachedPage; } } private static Page _CachedPage; public static string GetWebResourceUrl(Type type, string resource) { return CachedPage.ClientScript.GetWebResourceUrl(type, resource); } } You can now use GetWebResourceUrl in a Razor page like this: <!DOCTYPE html> <html <head> <script src="@WebUtils.GetWebResourceUrl(typeof(ControlResources),ControlResources.JQUERY_SCRIPT_RESOURCE)"> </script> </head> <body> <div class="errordisplay"> <img src="@WebUtils.GetWebResourceUrl(typeof(ControlResources),ControlResources.WARNING_ICON_RESOURCE)" /> This is only a Test! </div> </body> </html> And voila - there you have WebResources served from a non-Page based application. WebResources may be a on the way out, but legacy apps have them embedded and for some situations, like fallback scripts and some common image resources I still like to use them. Being able to use them from non-WebForms applications should have been built into the core ASP.NETplatform IMHO, but seeing that it's not this workaround is easy enough to implement.© Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET  MVC   Tweet (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • How to block internet access for wine applications?

    - by YSN
    Hello! Is it possible to prevent specific wine applications or any wine application from accessing the internet? When using certain apps under Windows, they were trying to access the internet from time to time without any obvious reason. I was able to prevent that behaviour with a personal firewall back then. Unfortunately I did not find an application level firewall in Ubuntu up to now. This is especially annoying when I am abroad using data-roaming with my 3G modem. Is there a way to prevent my wine-apps sending or receiving data without my knowledge. Thanks in advance! YSN

  • Address Regulatory Mandates for Data Encryption Without Changing Your Applications

    - by Troy Kitch
    The Payment Card Industry Data Security Standard, US state-level data breach laws, and numerous data privacy regulations worldwide all call for data encryption to protect personally identifiable information (PII). However encrypting PII data in applications requires costly and complex application changes. Fortunately, since this data typically resides in the application database, using Oracle Advanced Security, PII can be encrypted transparently by the Oracle database without any application changes. In this ISACA webinar, learn how Oracle Advanced Security offers complete encryption for data at rest, in transit, and on backups, along with built-in key management to help organizations meet regulatory requirements and save money. You will also hear from TransUnion Interactive, the consumer subsidiary of TransUnion, a global leader in credit and information management, which maintains credit histories on an estimated 500 million consumers across the globe, about how they addressed PCI DSS encryption requirements using Oracle Database 11g with Oracle Advanced Security.

  • JavaScript Intellisense Improvements with VS 2010

    - by ScottGu
    This is the twentieth in a series of blog posts I’m doing on the upcoming VS 2010 and .NET 4 release.  Today’s blog post covers some of the nice improvements coming with JavaScript intellisense with VS 2010 and the free Visual Web Developer 2010 Express.  You’ll find with VS 2010 that JavaScript Intellisense loads much faster for large script files and with large libraries, and that it now provides statement completion support for more advanced scenarios compared to previous versions of Visual Studio. [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Improved JavaScript Intellisense Providing Intellisense for a dynamic language like JavaScript is more involved than doing so with a statically typed language like VB or C#.  Correctly inferring the shape and structure of variables, methods, etc is pretty much impossible without pseudo-executing the actual code itself – since JavaScript as a language is flexible enough to dynamically modify and morph these things at runtime.  VS 2010’s JavaScript code editor now has the smarts to perform this type of pseudo-code execution as you type – which is how its intellisense completion is kept accurate and complete.  Below is a simple walkthrough that shows off how rich and flexible it is with the final release. Scenario 1: Basic Type Inference When you declare a variable in JavaScript you do not have to declare its type.  Instead, the type of the variable is based on the value assigned to it.  Because VS 2010 pseudo-executes the code within the editor, it can dynamically infer the type of a variable, and provide the appropriate code intellisense based on the value assigned to a variable. For example, notice below how VS 2010 provides statement completion for a string (because we assigned a string to the “foo” variable): If we later assign a numeric value to “foo” the statement completion (after this assignment) automatically changes to provide intellisense for a number: Scenario 2: Intellisense When Manipulating Browser Objects It is pretty common with JavaScript to manipulate the DOM of a page, as well as work against browser objects available on the client.  Previous versions of Visual Studio would provide JavaScript statement completion against the standard browser objects – but didn’t provide much help with more advanced scenarios (like creating dynamic variables and methods).  VS 2010’s pseudo-execution of code within the editor now allows us to provide rich intellisense for a much broader set of scenarios. For example, below we are using the browser’s window object to create a global variable named “bar”.  Notice how we can now get intellisense (with correct type inference for a string) with VS 2010 when we later try and use it: When we assign the “bar” variable as a number (instead of as a string) the VS 2010 intellisense engine correctly infers its type and modifies statement completion appropriately to be that of a number instead: Scenario 3: Showing Off Because VS 2010 is psudo-executing code within the editor, it is able to handle a bunch of scenarios (both practical and wacky) that you throw at it – and is still able to provide accurate type inference and intellisense. For example, below we are using a for-loop and the browser’s window object to dynamically create and name multiple dynamic variables (bar1, bar2, bar3…bar9).  Notice how the editor’s intellisense engine identifies and provides statement completion for them: Because variables added via the browser’s window object are also global variables – they also now show up in the global variable intellisense drop-down as well: Better yet – type inference is still fully supported.  So if we assign a string to a dynamically named variable we will get type inference for a string.  If we assign a number we’ll get type inference for a number.  Just for fun (and to show off!) we could adjust our for-loop to assign a string for even numbered variables (bar2, bar4, bar6, etc) and assign a number for odd numbered variables (bar1, bar3, bar5, etc): Notice above how we get statement completion for a string for the “bar2” variable.  Notice below how for “bar1” we get statement completion for a number:   This isn’t just a cool pet trick While the above example is a bit contrived, the approach of dynamically creating variables, methods and event handlers on the fly is pretty common with many Javascript libraries.  Many of the more popular libraries use these techniques to keep the size of script library downloads as small as possible.  VS 2010’s support for parsing and pseudo-executing libraries that use these techniques ensures that you get better code Intellisense out of the box when programming against them. Summary Visual Studio 2010 (and the free Visual Web Developer 2010 Express) now provide much richer JavaScript intellisense support.  This support works with pretty much all popular JavaScript libraries.  It should help provide a much better development experience when coding client-side JavaScript and enabling AJAX scenarios within your ASP.NET applications. Hope this helps, Scott P.S. You can read my previous blog post on VS 2008’s JavaScript Intellisense to learn more about our previous JavaScript intellisense (and some of the scenarios it supported).  VS 2010 obviously supports all of the scenarios previously enabled with VS 2008.
