  • Spring 3.0 REST implementation or Jersey?

    - by hnilsen
    Hi, SO! I'm currently trying to figure out which implementation of JSR-311 I'm going to recommend further up the food chain. I've pretty much narrowed it down to two options - Spring 3.0 with it's native support for REST - or use Sun's own Jersey (Restlets might also be an option). To me it doesn't seem to be much of a difference in the actual syntax, but there might be issues with performance that I haven't figured out yet. The service is meant to replace some heavy-duty EJB's and make a RESTful Webservice instead. The load is expected to be rather high, up in the 100k users per day (max) range, but will be seriously load balanced. Thanks for all your insights.

  • S3 browser upload via POST: unable to handle errors gracefully

    - by samf
    I am writing an app where I want the customer to be able to upload to Amazon S3 straight from the browser. I can make this work just fine. But when errors occur, I want to handle them more gracefully than splattering an XML document on the customer's screen. I have a scheme that I think would work, but it's failing. Here's what I'm trying: Create a form to do the upload, and store the form on S3 itself, in the same domain as the "action" attribute of the form. Redirect the customer to this form. Now their browser is sitting on https://<bucket>.s3.amazonaws.com/something. The page contains a hidden iframe. The form sets its target to the iframe. The load event handler looks at the contents of the iframe, and acts upon it. So, something like this: <iframe id="foo" name="foo" style="display: none" /> <form target="foo" action="https://<bucket>.s3.amazonaws.com/"> <input type="hidden" name="..." value="..." /> <input type="file" name="file" /> </form> with this javascript (using jquery): function handler() { var message = $("#foo").contents().find('message').text(); alert(message); } $("#foo").load(handler); Using firebug, I can see that the iframe contains an XML document, that contains a "message" node. However, the .find('message') always fails to find anything within the XML document. Notice that the action of the form has the same domain, port, and scheme as the document itself. So, I don't think that I should be running afoul of the same-origin policy. Right? But it fails every time. This is using Firefox and Google Chrome browsers. Thanks for any advice!

  • Change web service url for a suds client on runtime (keeping the wsdl)

    - by patanpatan
    Hi. First of all, my question is similar to this one But it's a little bit different. What we have is a series of environments, with the same set of services. For some environments (the local ones) we can get access to the wsdl, and thus generating the suds client. For external environment, we cannot access the wsdl. But being the same, I was hoping I can change just the URL without regenerating the client. I've tried cloning the client, but it doesn't work.

  • Ordering .each results in the view...

    - by bgadoci
    I am wondering if it is possible to dictate the order (i.e. :order = 'created_at DESC') within the view. I realize that logic in the view is not ideal but I seem to be having some problems locating where to affect this output. For instance, here is my code: <% @user.questions.each do |question| %> <%= link_to_unless_current h (question.title), question %> Created about <%= time_ago_in_words h(question.created_at) %> ago Updated about <%= time_ago_in_words h(question.updated_at) %> ago <%= link_to 'Edit', edit_question_path(question) %> | <%= link_to 'Destroy', question, :confirm => 'Are you sure?', :method => :delete %> <% end %> In my QuestionsController I have the following index action but it is not affecting the output from the code above. class QuestionsController < ApplicationController def index @questions = Question.all(:order => 'created_at DESC', :limit => 20) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @questions } end end end

  • Are your redirects HTTP compliant (absolute URI)?

    - by webbiedave
    In the Hypertext Transfer Protocol 1.1 spec, it states for the Location header: The field value consists of a single absolute URI. Location = "Location" ":" absoluteURI An example is: Location: http://www.w3.org/pub/WWW/People.html I have coded many an app that doesn't include the scheme and domain (i.e., /thankyou/) and every browser I've ever tested with redirects correctly. I'm wondering if it's imperative to go back and change all my redirect code or just ignore this part of the spec. Have many of you produced code that doesn't comply and will you go back and change it? Or will you just trust that clients will continue to resolve them well into the future? (going forward I will certainly adhere to this)

  • 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.

  • 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.

If i keep on moving from one page to another then a ajax request is made.. This request stops responding after 4 to 5 request... Why is it happening?

  • 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.

  • When asked "How do I make a website?" how do you answer?

    - by Luke CK
    A (non-technical) friend of mine has asked me how to make a website. I get this question all the time. After a few questions I found out that she has an idea that could turn into a commercial site. I described three options to her: a) Get a book/enroll in a class/follow some online tutorials and learn how to do it. She's pretty smart and her personality seems like a good match for this sort of thing so I'm sure she could learn but she doesn't have a lot of time spare. Maybe if she started with one of those WYSIWYG editors at first? I stressed that this would take a longer than a couple of weekends of playing around. b) Hire someone to build it. Ranges from ultra cheap to ultra expensive, crappy to good and everything in between. I didn't mention sites like Rentacoder because she hasn't worked on a project like this before and doesn't know what to ask for. At this stage she'd likely ask for a Youtube-MySpace-Google for a few hundred bucks because she doesn't yet understand just how much is involved. c) Find someone technical and partner up with them. I explained that this can either work really well or be a disaster because she'd have to give up some of her ownership of the idea. How do you respond in these situations?

  • 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?

  • what do you expect from flash in the near future?

    - by algro
    The recent article of steve jobs link made me think about the future of flash. I'm learning actionscript 3.0 in my studies but is it the right decision still to go for it? I was pretty sure that I will be able to build application in as3 for iphones/ipads in the near future. It seems to me, while I would stay with flash, the market will be polarized by apple and adobe and you will always work double for both clientele, or just lose half of them. Which decision would you take as a designer, if you were still at university and you intend to become a freelancer?

  • Widget_Controller for different types of data (MVC)

    - by steve-o
    Hello, I have a few widgets I need to show on a site - they are all relating to different types of data (e.g user, house). Each type of data and its relations is represented in specific models, but as far as a controller or helper is concerned, is it an ok plan to have a generic Widget controller/helper which generates the necessary widgets, even though each widget is dealing with distinct data? I don't really want to generate these widgets within the User and House controllers, as these controllers are dealing with different types of functionality. I'd imagine that the Widget_Controller could just contain static methods for generating these widgets, e.g: Widget_Controller::user_panel(); Does that make sense? Cheers!
