• With the advent of HTML 5, is there a point in using COMET anymore?

  - by h2g2java

  I am very tempted to use long wait http or periodic polling by the client to set up pseudo-sockets on the browser side, for an application that would be used publicly. But then on the 2nd thought, I am thinking HTML 5 is here. But on the 3rd thought, what is the percentage of browsers out there that remain non-HTML5 within 12 months, 24 months, 36 months? If there are at least 20% of browsers still incapable of HTML5, then I cannot depend on HTML5 because 20% of users not being able to access an application is a significant amount. What do you think, how would your advice be (to me and to developers in general)? Q1. Is there any point in rigging in COMET into an application anymore? I am thinking of gwt comet - http://code.google.com/p/gwt-comet/. Q2. Should we release a new public application within the next 2 months that is dependent on HTML5 sockets and tell non-HTML5 browser users "sorry, your browser version cannot access this application"? Or should we architect the apps to use communication like GWT RPC? Q3. I am also very distrustful of long wait http request. I have never used it before but I have a horrible feeling about it. I have been using 10 to 20 second client-side polling. Is long wait http request risky (risk of hanging a browser session)? Does long wait request present any additional security risk?

• Multiple login locations for an online app.

  - by Goro

  Hello, I am working on a browser based application that will have many users. The catch is that every user should have their own customized login page, but the actual application is the same for everyone, and needs to be in a central location. What is the most secure way of doing this? Would it make more sense to have a copy of the application for each user, and keep the database centralized? The projected number of users is not very high, probably around 20-80. Thank you,

• Can't use Visual Studio 2008 Designer with MVVMLight V3 SP1

  - by mcauthorn

  I wish I knew what I did to cause this, but I cannot use the Visual Studio 2008 Designer at all with with MVVMLight templates. I receive a "Could not create an instance of type 'ViewModelLocator'. in any of my xaml pages. The application builds and runs fine but only the designer is broken. In the App.xaml is <Application x:Class="ExcelReportGenerator.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:vm="clr-namespace:ExcelReportGenerator.ViewModel" xmlns:res="clr-namespace:ExcelReportGenerator.Resources" Startup="Application_Startup" mc:Ignorable="d"> <Application.Resources> <!--Global View Model Locator--> <vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True" /> </Application.Resources> I even receive the error when I create a brand new MVVMLight application. The interesting thing is if I use an express version of VS2010 I can view, edit and work in designer just fine. As much as I would love to go to VS2010, I can't right now convince IT to make that move.

• Audio/video streaming on Windows platform

  - by bushtucker

  I'm building an interactive language learning application to be used in a classroom environment. The idea is that a teacher should be able to talk to the students (=audio stream to all students), let students talk to each other (= audio P2P) in groups of two or more, let students watch a video coming from a the DVD player or coming from a media server. It should be possible to save the audio/video streams. The teacher should also be able to monitor, take-over or block the desktop of the students. The platform is Windows and it's a desktop application, no web application. The audio delay should be as minimal as poosible. Optionally a student sitting at home should be supported, but it's not a high priority. I am now finished with the classroom control part of the application (login, monitor, block, ...) and want to start the audio and video part. I've been evaluating several options like DirectX, GStreamer and SIP but now I have to make a decision. DirectX seems an obvious choice for the Windows platform, but it only lets me capture and playback audio and video. The encoding/decoding/network part I should do myself. GStreamer contains all kinds of options to capture/encode/stream/save audio and video streams. I've experimented a bit with it (ossbuild) and it does seem to involve a lot of trial and error to make something work: - microphone capture (via directsoundsrc) produces cracking noises on some computers - rtpL16 payloader didn't work well - streaming raw audio over the network only working at a sampling rate of 8000, no higher - there are a lot of errors when receiving mpeg4 video (bad I-frame), on some computers worse than others It is my impression that gstreamer is primary targetted at linux platforms. Development and support for the Windows platform seems to be a little behind. Nevertheless it's a powerful framework that could save me months and years of work. SIP seems to be able to do everything I want, but it is targeted towards telephony and IM. I don't know how flexible SIP is. It seems to me that the SIP layer would just be overhead as I already have a central (teacher) application that can control and setup all the streams. The interesting parts of frameworks like opalvoip and freeswitch are the actual audio/video capture, the encoding and transmission. Does anyone know how these interesting parts relate a framework like gstreamer? Are they easy to integrate into a custom application? Are they flexible enough? Does anyone have experience with all or one of these technologies? Maybe there are even other options I can look at? Many thanks for your advice

• Should I Solve this with Multithreading in Ruby?

  - by viatropos

  I have a strange case, here's the sequence of actions: User edits a document and hits save Application sends GET request to service Service sends POST request back to application in the middle of responding to the GET request Application, in the same state as when it made the GET request, responds to the POST request (sends document data) to service. Service sends data back to Application (responding to original GET request) Application handles the rest... The use case is this: I was thinking how can I make Yahoo Pipes POST data? Specifically, I want it to be able to update Google Docs when a user makes a change locally (on a custom editor). So user edits doc, makes GET request to Yahoo Pipes, Pipes makes a POST request back to App to get the document (Pipes can only make this type of POST request), App sends doc, Pipes formats data according to the Google API, Pipes responds to GET request with Google API formatted XML, App makes the post request. Theoretically, how would I accomplish this? It seems that I need to create a separate ruby Process for the GET request, and when Pipes sends the POST request, I find that process and send its output, then I'm stuck. This would cut out the need for a database for this particular case (I could save the stuff temporarily in a database, but that doesn't seem right). Any ideas? This would make it so I don't have to format things to the Google API in ruby, I could leave that to Pipes.

• WCF: Proxy open and close - whaaa?

  - by MikeMalter

  I am maintaing a windows form application using WCF and are using net.tcp internally. The lifecycle of our connections is GET/USE/CLOSE. We are having a problem with the application pool crashing with no trace. In looking at netstat, I can see when I come into the application as we have a login service. However, even though we are creating the proxy in a using statement, the connection in netstat does not go away until I physically close the application. Is this right? Should I be doing something diffent on the client to force the connection to close? So if the connection stays open, does it stay open for the duration of the openTimeout setting and then gets torn down? Thanks.

• Accessing the DI container from anywhere

  - by ChrisR

  I've implemented the Symfony2 Dependency Injection container in my Zend Framework project and it works fine in the MVC layer of my application. I've initialized the DIC in my bootstrap and can access it anywhere by calling: Zend_Controller_Front::getInstance()->getParam('bootstrap')->getDic() The problem is that there are some parts of my application that do not utilize the Zend Framework application/MVC layer. My CLI tools for example. I could perfectly initialize a new DIC there but that would just be some copy paste work from the Bootstrap file which is asking for trouble down the road (DRY principles, etc) Is it a better solution to make my DIC available in the Zend_Registry or as a singleton called by a static method DIC::getInstance() for example? I know Registry and singletons are considered bad things but the DIC is such a high level part of the application that I will probably never run into the problems that make it a bad thing. Is this a good solution or are there better ways of accomplishing a globally accessible DIC?

• Can't reach the new zend controller/view

  - by Zakaria

  Hi, I've installed Zend Studio 7.1.1 that contains 1.9 framework. For the server side, I use easyphp (very similar to wamp) When I create the project, I obviously obtain this architecture: MyProject |-- application | |-- Bootstrap.php | |-- configs | | `-- application.ini | |-- controllers | | |-- ErrorController.php | | `-- IndexController.php | |-- models | `-- views | |-- helpers | `-- scripts | |-- error | | `-- error.phtml | `-- index | `-- index.phtml |-- library |-- public | |-- .htaccess | `-- index.php `-- tests |-- application | `-- bootstrap.php |-- library | `-- bootstrap.php `-- phpunit.xml To launch the project, I enter: http://127.0.0.1/MonProjet/public/index.php But when I create a new controller (TestController.php) and the associated view (application.views/test/index.phtml) and when I enter: http://127.0.0.1/MonProjet/public/test the browser returns the error : object not found (404). although I activated the mod_rewrite LoadModule rewrite_module modules/mod_rewrite.so So, how can I set the routing mechanism to reach the new controllers and their views? Thank you very much, regards.

• Hibernate or JPA or JDBC or ???

  - by Yatendra Goel

  I am developing a Java Desktop Application but have some confusions in choosing a technology for my persistence layer. Till now, I have been using JDBC for DB operations. Now, Recently I learnt Hibernate and JPA but still I am a novice on these technologies. Now my question is What to use for my Java Desktop Application from the following? JPA Hibernate JDBC DAO any other suggestion from you... I know that there is no best choice from them and it totally depends on the complexity and the requeirements of the project so below are the requirements of my project It's not a complex application. It contains only 5 tables (and 5 entities) I wan't to make my code flexible so that I can change the database later easily The size of the application should remain as small as possible as I will have to distribute it to my clients through internet. It must be free to use in commercial development and distribution.

• SMS war continues, ideas welcome

  - by Pavel Radzivilovsky

  I am trying to make U9 telit modem send SMS messages. I think I handle protocol correctly, at least, I manage to send them, but only under these circumstances: the native application was executed beforehand, and killed by task manager (without giving it a chance to initialize things). It looks like the supplied application is good at doing certain initialization/deinitialization which is critical. I also see the difference between the two states in output of AT+CIND command. When I am trying to do things on my own, it returns zeroes (including signal quality), but when I run the same command after killing the native application, the output looks reasonable. I am out nearly of ideas. I have tried many things, including attempts to spy at modem's COM ports (didn't work). Haven't tried setting windows hooks to see what the application is trying to get thru. Perhaps you have encountered a similar situation?

• @synthesize with UITabBarController?

• Java Can't Find File when Running through Eclipse

  - by derekerdmann

  When I run a Java application that should be reading from a file in Eclipse, I get a java.io.FileNotFoundException, even though the file is in the correct directory. I can compile and run the application from the command line just fine; the problem only occurs in Eclipse, with more than one project and application. Is there a setting I need to change in the run configurations or build paths to get it to find the file correctly?

• Separation of static and dynamic content in Java EE applications

  - by Dan

  We work with IBM products and we typically use IBM Http Servers (read Apache) as a reverse proxy for our application servers. For performance reasons we serve static content (.gif, .jpg, .css, .html etc.) from our http servers, to ease the burden a bit from the application server. So far, we have to distribute files to http server and configure it manually (writing custom scripts at best.) The problem is the effort needed to keep everything in synch, especially when you need to update the app. Does any Java EE product support this “out of the box”? Is there a way to have application server do this automatically, like in cluster configuration for example, where master node is in charge of distributing the application to other nodes and for keeping everything in synch.

• Advantages/disadvantages of browser-based interface vs. graphics

  - by Josh

  Hello everyone, I'm in the design phase for a desktop-based application. Because of the nature of this particular application, I believe it would benefit greatly from a web-based approach (i.e., allowing a user to interface with the application through a browser running in kiosk mode) in order to leverage the simplicity of HTML/CSS/JS and the availability of many great JS interface plugins. Does taking this approach (rather than coding in a native or cross-platform graphics library) come with any gotchas?

• memory issue iPad 4.2 crashes

  - by Manoj Kumar

  I am developing a application which receives 600-700 KB of XML data from the server. I have to do some manipulations in that data so once received the data the memory increases to 600 KB to 2 M.B. Already view occupied 4 M.B of memory in the application. So while processing the XML data i m doing some manipulation(pre-parsing) and the memory increases to 600 K.B to 2 M.B and finally decreases to 600 K.B. due to increase in memory, application gives the memory warning. While getting memory warning i m releasing all the views in the navigation controller but it releases only 1 M.B of memory. Even though I release all the views the application is crashing. Please help me out in this issue. It happens in iPad 4.2. Thanks in advance

• Zend Framework command line see errors

  - by sims

  I'm using a method outline by gregor (http://stackoverflow.com/questions/143320/create-cronjob-with-zend-framework) to create command line execution for parts of my application such as cron jobs, admin tasks, and the like. It works, however, no errors get reported when I create a new object that has not been defined (misspelling) and other such mistakes. I would have thought that php would report an error, but it fails silently. What is the reason for this? Is there a better way to achieve my goal? Or how can I implement this so that I can see errors? Many thanks! Here is the code: in public/index.php if(!defined('RUN_APP') || RUN_APP == true) { $application->bootstrap()->run(); } application/cron.php define("RUN_APP",false); require(realpath('/var/www/domain/public/index.php')); $application->bootstrap(); //the rest

• Can a war file be deployed on any server?

  - by Roshan

  Please pardon me if this question is silly. Suppose I develop a j2ee web application using srping framework and a MS SQL Server database, using a Webspphere application server. I later create a war file for this application. Can I deploy this war file on a tomcat server without any change in code? Or my question is can this be hosted by web hosting which provides only Tomcat servers? If yes, is there any change in code required? If it cannot be deployed, can you please suggest me what to do, because I havent developed any application on a tomcat server. All the applications that I have developed have been on Websphere App Server using RAD.

• NETBEANS JAVADB - How do I integrate a JavaDB DataBase into my main Java Package

  - by Stefanos Kargas

  JAVA I am working on a desktop application which uses JavaDB. I am using NetBeans 6.8 and JDK 6 Update 20 I created the database I need and connected to it through my application using ClientDriver: String driver = "org.apache.derby.jdbc.ClientDriver"; String connectionURL = "jdbc:derby://localhost:1527/myDB;create=true;user=user;password=pass"; try { Class.forName(driver); } catch (java.lang.ClassNotFoundException e) { e.printStackTrace(); } try { schedoDBConnection = DriverManager.getConnection(connectionURL); } catch (Exception e) { e.printStackTrace(); } This works fine. But in that case the service of the database comes from NetBeans. If I move my application to another PC I won't be able to access my database. How can I integrate my JavaDB into my application?
