  • Should I use Google Web Toolkit for my new webapp?

    - by balint.miklos
    I would like to create a database backed interactive AJAX webapp which has a custom (specific kind of events, editing) calendaring system. This would involve quite a lot of JavaScript and AJAX, and I thought about Google Web Toolkit for the interface and Ruby on Rails for server side. Is Google Web Toolkit reliable and good? What hidden risks might be if I choose Google Web Toolkit? Can one easily combine it with Ruby on Rails on server side? Or should I try to use directly a JavaScript library like jQuery? I have no experience in web development except some HTML, but I am an experienced programmer (c++, java, c#), and I would like to use only free tools for this project.

  • How to handle BL cache for multiple web applications?

    - by Eran Betzalel
    I recently received a project that contains multiple web applications with no MVC structure. For starters I've created a library (DLL) that will contain the main Business Logic. The problem is with Caching - If I use the current web context cache object than I might end up with duplicate caching (as the web context will be different for every application). I'm currently thinking about implementing a simple caching mechanism with a singleton pattern that will allow the different web sites (aka different application domains) to share their "caching wisdom". I'd like to know what is the best way to solve this problem.

  • Has glassfish 2.1.1 a bug handling http request and handle them twice?

    - by marabol
    I'm using glassfish 2.1.1. I've watched a mysterious http/webservice-call handling. It seams an http request is handled by two different threads. After http basic authentication the first thread is faster. Persisting some data end, but writing response fails in glassfish internal. The second thread fails, because it tries to persist identical data and there are (unique) constrain failures. The response (the failure) of second thread was delivered to client. I don't won't discuss the behavior with the unique constrain failure. I've improve the webservice, so it can handle this better, because it could be happen anytime, that the client send the ws call a second time. But I think, glassfish 2.1.1 has an bug handling http request. Is there any known issue? Have I done an mistake?

  • Need strategy to phone home to a Pyton web app and check licensing information for a commercial Wind

    - by Cornish
    What's a good strategy for building licensing checking into a Windows desktop app using a Python web application? This is a very open ended question because I don't have the slightest clue how to start to build this feature. What I do have is a number of general concerns: I have developed a commercial Windows desktop application and I want to make money from it but I don't want to build the licensing into the app since it's inevitable that someone will create a keygen or a crack, circulate it online and then it's 'game over' for me. So my idea was to create a web application where people could purchase a license key that is generated by the web app and every time the desktop application is started up, it will 'phone home' to the web app to check whether the license is valid and whether it seems to be in use at multiple locations. I'm just not sure how to do this. Would appreciate any general technical strategies and/or pointers to libraries/modules that might be of use.

  • Good php editor

    - by Web Developer
    i have seen through other questions on the topic but most are a bit old. I looking for a good editor for developing on PHP in Linux(ubuntu). Here is my requirements Basic editor features Free Light-Weight Syntax highlighting Code Folding (class,function,if/else/while/foreach block) Code completion Invalid Syntax/Error highlighting as you type Auto code intending Snippet support(pieces of custom or language specific codes that i can insert) Extendable support It would be great if it had the following Debugging support WYSIWYG Code formatting Framework support(cakephp/yii/zend/smarty) Testing support Todo Native look and feel(Gnome) Flex/ROR support is welcome but not a requirement Mysql support I have tried the following editors Netbeans - it bloated, resource hogging and doesnt not have a native look and feel. Eclipse is okay but i cant fold if/while blocks and slow. Gedit can be extended and i have tried it but still i could not fold code or show error. I currently use Geany but it doesn't inform me of syntax errors as i type. If you have ways to solve the problems with above editors they too are also welcome

  • Different database for Membership and our web data or use just one?

    - by Jesus Rodriguez
    Is better to keep our Membership stuff on the DefaultConnection and create another connection (another database) for our data? Or just one database for all? If I have a MyAppContext and I want migrations for that context, It seems that I cannot have migrations for UserContext (In other words, I can just migrate one context) So, having two different databases I can migrate or the users (maybe membership migration is weird) or the web data. Or, I can mix the UserContext and MyAppContext in one UserAndAppContext and migrate all in one place, but this mixing also seems weird. What's the normal way to do this, one or two databases and what should be migrated?

  • Can I retain a Google apps session token permanently for a specific user who logs into my google app

    - by Ali
    Hi guys, is it possible to retain upon authorization a single session token for a user who signs into my gogle application. CUrrently my application seems to every now and then require the user to authenticate into google apps. I think it has to do with session dying out or so. I have the following code: function getCurrentUrl() { global $_SERVER; $php_request_uri = htmlentities(substr($_SERVER['REQUEST_URI'], 0, strcspn($_SERVER['REQUEST_URI'], "\n\r")), ENT_QUOTES); if (isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on') { $protocol = 'https://'; } else { $protocol = 'http://'; } $host = $_SERVER['HTTP_HOST']; if ($_SERVER['SERVER_PORT'] != '' && (($protocol == 'http://' && $_SERVER['SERVER_PORT'] != '80') || ($protocol == 'https://' && $_SERVER['SERVER_PORT'] != '443'))) { $port = ':' . $_SERVER['SERVER_PORT']; } else { $port = ''; } return $protocol . $host . $port . $php_request_uri; } function getAuthSubUrl($n=false) { $next = $n?$n:getCurrentUrl(); $scope = 'http://docs.google.com/feeds/documents https://www.google.com/calendar/feeds/ https://spreadsheets.google.com/feeds/ https://www.google.com/m8/feeds/ https://mail.google.com/mail/feed/atom/'; $secure = false; $session = true; //echo Zend_Gdata_AuthSub::getAuthSubTokenUri($next, $scope, $secure, $session);; return Zend_Gdata_AuthSub::getAuthSubTokenUri($next, $scope, $secure, $session).(isset($_SESSION['domain'])?'&hd='.$_SESSION['domain']:''); } function _regenerate_token() { global $BASE_URL; if(!$_SESSION['token']) { if(isset($_GET['token'])): $_SESSION['token'] = Zend_Gdata_AuthSub::getAuthSubSessionToken($_GET['token']); return; else: _regenerate_sessions(); _redirect(getAuthSubUrl($BASE_URL . '/index.php?'.$_SERVER['QUERY_STRING'])); endif; } } _regenerate_token(); I know I'm doing it all wrong here and I don't know why :( I have a CONSUMER SECRET code but only use it whereever I need to access a google service. However something is wrong with my authentication as the user has to periodically 'grant access to my application' and reauthorise himself... help please

  • What Happens to Commit Logs on a Branch After Merging?

    - by Levi Hackwith
    Scenario: Programmer creates a branch for project 'foo' called 'my_foo' at revision 5 Programmer makes multiple changes to multiple files as he works on the 'my_foo' feature. At the end of each major step, say adding several new functions to class, the programmer does an svn commit on the appropriate files therefore committing them to the branch After several weeks and many commits later (each commit having a commit log describing what he did), the programmer merges the branch back into the trunk: #Assume the following is being done from inside a working copy of the trunk: svn merge -r 5:15 file:///path/to/repo/branches/my_foo Hazzah! he's merged all his changes back into trunk! There's much rejoicing and drinking of Mountain Dew. Now let's say another programmer comes along a week later and updates their working copy from revision 5 to revision 15. "Wow", they say. "I wonder what's changed since revision 5". The programmer then does an svn status on their working copy and they get something like this: ------------------------------------------------------------------------ r15 | programmer1 | 2010-03-20 21:27:04 -0400 (Sat, 20 Mar 2010) | 1 line Merging Version 2.0 Changes into trunk ------------------------------------------------------------------------ r5 | programmer2 | 2010-02-15 10:59:55 -0500 (Mon, 15 Feb 2010) | 1 line Added assets/images/tumblr_icon.png to trunk What the heck happened to all the notes that the other programmer put in with all of his commits in his branch? Do those not get pulled over during a merge? Am I crazy or just forgetting something?

  • What is a quick way to indent a block of text with spaces for use within a web browser?

    - by ændrük
    I occasionally have the need to indent a block of text with spaces for use within a web browser, for example, when formatting a code block on this site or in a post on Launchpad. So far I've just done it by hand by copying four spaces to the clipboard and then mashing keys really fast: ?, Home, Ctrl+V (repeat) What is a quicker way to accomplish this, e.g. copying and pasting to another program? a Firefox or Chrome browser extension? a command to directly modify the clipboard contents? an auto-typing program?

  • Anyone have an XSL to convert Boost.Test XML logs to a presentable format?

    - by Stuart Lange
    I have some C++ projects running through cruisecontrol.net. As a part of the build process, we compile and run Boost.Test unit test suites. I have these configured to dump XML log files. While the format is similar to JUnit/NUnit, it's not quite the same (and lacks some information), so cruisecontrol.net is unable to pick them up. I am wondering if anyone has created (or knows of) an existing XSL transform that will convert Boost.Test results to JUnit/NUnit format, or alternatively, directly to a presentable (html) format. Thanks!

  • How web server choose between unicode and utf-8 for accentued characters?

    - by jacques
    I have a web server with my ISP which replaces in the urls the accentued characters by their unicode values: for instance é (eacute) is translated to %e9 (dec 233). For testing I use locally Easyphp which translate those characters by their utf-8 equivalence: é is then replaced by the well known sequence %c3%a9 (é)... Browsers served by Easyphp don't decode unicode values but they do if running locally (utf-8 and non converted accent also)... I have been unable to find where this behavior is configured in the server. This is a problem as some urls are built by my application using the php rawurlencode() which seems to always encode with unicode values on both servers. Any idea? Thanks in advance.

  • Can a web app in xul:iframe access functions from its parent XUL file?

    - by oskar
    I want to deploy a web app as a self-contained program using XULRunner. I'm simply loading it in a xul:iframe tag within the main XUL file. It works, but I want the web app to have access to XUL components, specifically nsiFilePicker. My tentative solution is to run the xul:iframe with escalated privileges (by omitting the "type" attribute), wait for the xul:iframe to load, then define a javascript function that the web app will then call. <window id="main" width="800" height="600" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <iframe id="contentview" src="web/index.html" flex="1"/> <script> //listen for XUL window to load window.addEventListener("load",Listen,false); function Listen() { var frame = document.getElementById("contentview"); frame.addEventListener("DOMContentLoaded", DomLoadedEventHandler, true); } //listen for iframe to load function DomLoadedEventHandler() { //set function in iframe called testMe() var frame = document.getElementById("contentview"); frame.contentWindow.testMe = function () { alert("This is a test"); }; } </script> </window> ...and then in the index.html file of the web app... <script> testMe(); </script> This doesn't seem to work. Does anyone have any suggestions?

  • Can I use a *.tag from another *.tag file in the same /WEB-INF/tags folder?

    - by Ytsejammer
    Hello, I am trying to refactor my JSP code so that a small conditional test condition gets reused through a *.tag file. There are some big parts of my UI that depend on the value of a two-state property of an object present in the request. Let's say the property is 'gender' and the object is of type Person. Like I said, I would like to simplify & centralize the test on the gender property using a tag. For this purpose, I created two tag files: /WEB-INF/tags/if-male.tag /WEB-INF/tags/if-female.tag Now, I have another tiny spot that gets repeated in all over my application; let's say is the salutation to my site user. With this idea, I created a tag like this: /WEB-INF/tags/salutation.tag As you can imagine, I am trying to use the if-male/if-female test within the salutation.tag file to output 'Mrs.' or 'Mr.' like this: <%@ tag body-content="empty" %> <%@ taglib prefix="g" uri="/WEB-INF/tags" %> <g:if-male> Mr. </g:if-male> <g:if-female> Mrs. </g:if-female> Is the use of the if-male/if-female tags legal within the salutation.tag file? I have tried with such arrangement, but it looks like the JDeveloper 10.1.3.4 compiler gets confused and cannot deal with the salutation.tag tag invoking the other two tags in the same 'library' (folder under /WEB-INF/tags). The reference works perfectly in Jetty 6 and it looks like it works as well if I deploy the application to OC4J directly without relying on JDeveloper to pre-compile all my JSPs. I hope someone can shed some light on this. Thanks, YJ

  • Is there an alternative to javascript for the web that can do multi-threading and synchronous execution?

    - by rambodash
    I would like to program web applications as I do with desktop programming languages, where the code is synchronously executed and browser doesn't freeze when doing loops. Yes I know there are workarounds using callbacks and setTimeout, but they are all workarounds after all and they don't give the same flexibility when programming in the orthodox way I've been looking at Dart as a possibilty, but I can't seem to find where it says it can do either of these. The same with haxe, emscript, and the hundreds of other converters that try to circumvent javascript. In the end it gets converted to Javascript so you ultimately have to be conscious about asynchronous/multi threading.
