  • Best way to delay access to static web pages until services become available with J2EE

    - by Dean Povey
    I have a J2EE application front-ended by a bunch of GWT pages. When the server is starting up, it is possible that these static pages can be accessed before the services required to implement the GWT RPC calls (database etc) are available. I wondering what the best approach is to prevent a user accessing this static content before these services become available. For the purpose of this exercise, assume that there is an isInitialized() method somewhere. I am happy with either a page displaying an error message or simply refusing the connection.

  • JQuery: Read each line of an element

    - by Sarfraz
    Hello, Suppose I have this html markup: <div id="wrapper"> $(function(){ // hide all links except for the first $('ul.child:not(:first)').hide(); $("a.slide:first").css("background-color","#FF9900"); $('ul.parent a.slide').click(function(){ $('ul.parent a.slide').css("background-color","#3399FF"); $('ul.parent a.slide').mouseout(function(){ $(this).css("background-color","#3399FF"); }); $('ul.parent a.slide').mouseover(function(){ $(this).css("background-color","#66CC66"); }); }); }); </div> What is the easiest way to read each line of code present in the div. How do I extract each line of code from that div or loop over each line styling in any way I want. Thanks

  • Challenging yourself as a programmer?

    - by Kevin
    We used to be a Coldfusion development shop before hopping over to PHP in 2008, now we primarily develop custom Drupal websites. I enjoyed going from CF to PHP, but I feel like I am getting a bit stale. I have been looking at different things like Ruby, Python, Obj C (iPhone). The problem is, there just isn't enough time in the day. What would be a fun new thing to learn that would refresh me a bit and challenge myself to learn more?

  • Socket Programming for the Web

    - by Benny
    I have to interact with a legacy system that accepts socket communication and messages. My goal is to make the application cross-platform, but I need the ability to push messages to the client (i.e. - .NET's WCF, Java's Comet) and detect when the user closes out of their browser to destroy the socket. I have built a prototype of .NET wrapper + WCF + Silverlight but it is so disconnected it is difficult to manage the state of the user and seems to be a nightmare to support. All of that considered, what would be my best option?

  • Displaying message if no photo present...

    - by bgadoci
    I am using the code: <%= image_tag site.photo.url(:small) if site.photo.file? %> to tell my app to display nothing if there is no photo associated with a particular post (site in this case). Is there a way to render a message along w/ this. For instance "no image with the post". I tried simply doing <%= if site.photo.file? %> <p> no image with this site </p> <% end %> But that doesn't seem to work. New to ruby and rails if you can't tell.

  • MySQL Query, Date Range From "Blacklist"

    - by erbaker
    I have 2 databases. One is properties and the other is dates. In dates I have associated the land_id and a date (In YYYYMMDD format) which means that the date is not available. I need to formulate a query that a user can specify a start and end date, and then choose a property for which dates are available (not in the date database). How do airline and hotel websites do this kind of logic? I was thinking about taking the date range and picking all days in between and doing a query where the dates do not match and ordering it by number of results, but I can see how that could easily turn into an intense query. CREATE TABLE IF NOT EXISTS `dates` ( `id` int(11) NOT NULL AUTO_INCREMENT, `land_id` int(11) NOT NULL, `date` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=44 ; -- -- Dumping data for table `dates` -- INSERT INTO `dates` (`id`, `land_id`, `date`) VALUES (43, 1, '20100526'), (39, 1, '20100522'), (40, 1, '20100523'), (41, 1, '20100521'), (42, 1, '20100525');

  • The Wheel Invention - Beneficial For Learning?

    - by Sarfraz
    Hello, Chris Coyier of css-tricks.com has written a good article titled Regarding Wheel Invention. In a paragraph he says: On the “reinventing” side, you benefit from complete control and learning from the process. And on the very next line he says: On the other side, you benefit from speed, reliability, and familiarity. Also often at odds are time spent and cost. He is right in both statements I think. I really like his first statement. I do actually sometimes re-invent the wheel to learn more and gain complete control over what I am inventing. I wonder why people are so much against that or rather biased. Isn't there the benefit of learning and getting complete control or probably some other benefits too. I would love to see what you have to say about this.

  • Virtual PC (XPMode) - How to access Webserver on guest from host

    - by sannoble
    I have Windows XP running inside Windows 7 via Virtual PC (XPMode) and installed Zend Server CE on the virtual XP guest. The webserver is running and can be accessed on the guest, but I cannot access the webserver from the Win7 host. I configured a static IP address and subnet of 255.255.255.0 on the guest and can ping this IP from the guest but not from the host. The other way it works fine, i.e. I can ping the host from the guest. I can also access the internet from the virtual XP guest. I tried different Network Options in the VirtualPC settings, but nothing helps. Googling the topic I couldn't find anything helpful yet. Any idea, what I could try to access the webserver on the virtual XP guest from the Win7 host?

  • What are the typical reasons Javascript developed on IE fails on Firefox?

    - by lwburk
    Inspired by this post it occurs to me that I often suffer from the opposite problem. That is, I've got code in a legacy application designed only for Internet Explorer and I need to get it to work in Firefox. For example, I recently worked on an app that made heavy use of manually simulating click events, like this: select.options[0].click(); ...which completely broke the application in Firefox. But you wouldn't find that information in the answers to the other question, because that's not something you'd ever even attempt if your app first targeted Firefox. What other things should a developer updating a legacy IE-only application look for when migrating to modern browsers?

  • Changing overflow from div dynamically [closed]

    - by user552669
    Hello comunnity! I am filling a div using JQuery. This div has the CSS property 'overflow' set to 'auto' (to display scrollbars because the div has a lot of HTML inside). But the DIV doesn't display the scrollbars. I think that the problem is that I'm setting the CSS property using CSS and the DIV is filling dynamically. How can I do to display scrollbars if the HTML inside the DIV doesn't fit, but dynamically? I'm trying to set the property manually after fill the div, but didn't work: function createWB(tag){ // Fill the div // ... // Set the scrollbars $('.tab_content').css('overflow','auto'); } If a set the property to 'scroll', the scrollbars appear, but disabled. Thanks in advance! :)

  • Visual Studio 2008 - Assemblies are not loaded into Modules after relocating the website and project

    - by user296861
    I recently moved the asp.net website solution folder (along with class projects) to different location. As the result, visual studio doesn't stop at break points, and I could not able to debug. I see none of my assemblies at Debug Windows Modules; only microsoft assemblies are loaded. I have also deleted all bin folder and re-referenced all projects. But still no luck. Thanks in advance!

  • steam condenser java errors

    - by w0rm
    I've been working on a little project involving Steam Condenser, a Steam API written in Java, but I haven't been able to actually do anything with it. I'll explain. This is what the wiki tells me: SteamId id = new SteamId("demomenz"); GameStats stats = id.getGameStats("tf2"); List achievements = stats.getAchievements(); The problem is, eclipse doesn't like it apparently, as it spits out this error: The constructor SteamId(String) is undefined and it gives me the option to change it to: SteamId id = new SteamId("demomenz", false); But at this point a different error comes out: The constructor SteamId(Object, boolean) is not visible So, I'm assuming this function is internal to the API, and should not be called from the outside. If anyone is familiar with this, or has a clue on why I'm getting this error (I'm fairly new to Java development), an answer would be greatly appreciated. UPDATE: The constructor SteamId(String) is undefined This is if I use SteamId.create(ConvertedID); (ConvertedID is a String containing the Steam64 ID). At this point I believe this API is not that well written, at least for java. Any other idea?

  • a question related to Google Translate

    - by Robert
    Hi all, it works perfectly fine if I paste the following URL directly into my IE address bar: http://translate.google.cn/translate?hl=zh-CN&sl=zh-CN&tl=en&u=http%3A%2F%2Fnews.baidu.com%2Fns%3Fword%3D%25B0%25C2%25B0%25CD%25C2%25ED it will translate some Chinese news pages into English ones. but if I call this address in a Java program like: Process q=Runtime.getRuntime().exec("cmd /c start http://translate.google.cn/translate?hl=zh-CN&sl=zh-CN&tl=en&u=http%3A%2F%2Fnews.baidu.com%2Fns%3Fword%3D%25B0%25C2%25B0%25CD%25C2%25ED"); It will only return to the Google translate main page. Wonder what went wrong there. and it would be great if you help me how to realize this(opening the Google translated result page simplying by supplying the URL,in a Java program). Many thanks.

  • How do I serve a large file using Pylons?

    - by Chris R
    I am writing a Pylons-based download gateway. The gateway's client will address files by ID: /file_gw/download/1 Internally, the file itself is accessed via HTTP from an internal file server: http://internal-srv/path/to/file_1.content The files may be quite large, so I want to stream the content. I store metadata about the file in a StoredFile model object: class StoredFile(Base): id = Column(Integer, primary_key=True) name = Column(String) size = Column(Integer) content_type = Column(String) url = Column(String) Given this, what's the best (ie: most architecturally-sound, performant, et al) way to write my file_gw controller?

  • Are there any new Eclipse distributions?

    - by leeand00
    I've been using EasyEclispe for a long time, and I've noticed that they haven't really kept up-to-date with the main Eclipse distro. So I was wondering if anybody knew of an EasyEclipse-like distribution that would contain common things people in different areas of Java/Groovy development might need.

  • Slick PHP based image manager for managing user profile images

    - by franko75
    Hi, I'm just throwing this out there as I'm plodding my way through creating a Member Photo album on a site i'm working on, where they can login and upload their photos to a personal gallery. I want this to be nice and lightweight, but still slick and "modern" with a modal based interface for the user. I'm surprised though that there is seemingly nothing open source out there which fits the bill - I've done a few searches on Google to no avail and can't seem to find anything. Lots of bloated photo galleries out there but nothing looks like it has been developed using more recent technologies. Is anyone aware of anything which might suit what I'm looking for? I'm fully prepared to try and code it myself but I'd be delighted if I didn't have to! Pure laziness you might say, but there's no point reinventing the wheel.
