  • What's the difference between the code inside a finally clause and the code located after catch clause?

    - by facebook-100005613813158
    My java code is just like below: public void check()throws MissingParamException{ ...... } public static void main(){ PrintWriter out = response.getWriter(); try { check(); } catch (MissingParamException e) { // TODO Auto-generated catch block out.println("message:"+e.getMessage()); e.printStackTrace(); out.close(); }finally{ out.close(); } //out.close(); } Then, my confusion is: what the difference if I put out.close() in a finally code block or if I just remove finally code block and put out.close() behind catch clause (which has been commented in the code). I know that in both ways, the out.close() will be executed because I know that whether the exception happened, the code behind the catch clause will always be executed.

  • System.getProperty("user.dir") cannot get my project root path ,but the path which my eclipse is located

    - by facebook-100005613813158
    As the title goes , I have class named GetException.java,inside it ,I read a xml file in a static code block like(Because this document is shared): static{ ... document = db.parse(new File(System.getProperty("user.dir")+"/src/exception/ExceptionCode.xml")); ... } To test if the file path is correct, I write a main function just inside GetException.java, it proves that the path is correct ,xml file can be read successfully. My project root dir is "/home/wuchang/workspace/MongodbI". But When this Class is loaded from other class,such as I called one of its static functions , it reports the error message: /home/mrs/??/eclipse/src/exception/ExceptionCode.xml (No such file or directory) /home/mrs/??/eclipse/ is actually my eclipse installation directory.So , I wander how System.getProperty("user.dir") returned the eclipse installation directory to me ,instead of my project root directory?

    Hi I would like to get the contents of my FB app's wall into my iPhone app. The contents on the wall are directly posted there by me and not obtained from any database. Can someone please point me to the documentation where I can get the information for accessing these messages/their comments from my iPhone app? I searched on the Facebook wiki, but it takes me to the github page for FB-Connect on iPhone, nothing where I can see all the API calls possible. Thanks.

  • HTTP Builder/Groovy - lost 302 (redirect) handling?

    - by Misha Koshelev
    Dear All: I am reading here http://groovy.codehaus.org/modules/http-builder/doc/handlers.html "In cases where a response sends a redirect status code, this is handled internally by Apache HttpClient, which by default will simply follow the redirect by re-sending the request to the new URL. You do not need to do anything special in order to follow 302 responses." This seems to work fine when I simply use the get() or post() methods without a closure. However, when I use a closure, I seem to lose 302 handling. Is there some way I can handle this myself? Thank you p.s. Here is my log output showing it is a 302 response [java] FINER: resp.statusLine: "HTTP/1.1 302 Found" Here is the relevant code: // Copyright (C) 2010 Misha Koshelev.

  • How does Facebook chat avoid continuous polling of the server?

    - by Chad Johnson
    I am trying to understand how Facebook's chat feature receives messages without continuously poling the server. Firebug shows me a single GET XmlHttpRequest continuously sitting there, waiting for a response from the server. After 5 minutes, this never timed out. How are they preventing timeout? An AJAX request can just sit there like that indefinitely, waiting for a response? Can I do this with JSONRequest? I see this at json.org: JSONRequest is designed to support duplex connections. This permits applications in which the server can asynchronously initiate transmissions. This is done by using two simultaneous requests: one to send and the other to receive. By using the timeout parameter, a POST request can be left pending until the server determines that it has timely data to send. Or is there another way to let an AJAX call just sit there, waiting, besides using JSONRequest?

  • iphone poll application to sync with myspace or facebook poll.

    - by Zach
    Hi, We are developing an iphone application, which requires us to add polling(survey) functionality in the app. We also have same poll in either MySpace or Facebook. We have to sync the polling data to our iphone application. How can we achieve this? We have found some third party polling service provider like Zoomerang, Poll Daddy polls, etc., but they don't have supporting API for iphone application or at least one we are not aware of. If anyone can shed light on this on how to proceed with this, it will be really very helpful. Thanks in advance. Zach.

  • Why Shouldn't I Programmatically Submit Username/Password to Facebook/Twitter/Amazon/etc?

    - by viatropos
    I wish there was a central, fully customizable, open source, universal login system that allowed you to login and manage all of your online accounts (maybe there is?)... I just found RPXNow today after starting to build a Sinatra app to login to Google, Facebook, Twitter, Amazon, OpenID, and EventBrite, and it looks like it might save some time. But I keep wondering, not being an authentication guru, why couldn't I just have a sleek login page saying "Enter username and password, and check your login service", and then in the background either scrape the login page from say EventBrite and programmatically submit the form with Mechanize, or use an API if there was one? It would be so much cleaner and such a better user experience if they didn't have to go through popups and redirects and they could use any previously existing accounts. My question is: What are the reasons why I shouldn't do something like that? I don't know much about the serious details of cookies/sessions/security, so if you could be descriptive or point me to some helpful links that would be awesome. Thanks!

  • Twitter and Facebook on iPhone - save sessions across app launches?

    - by lostInTransit
    Hi I am using OAuth for twitter and fb-connect for facebook authentication in my iPhone app. Is it possible to save the user sessions across app launches? i.e. if the user logs in once, the next time they launch the app, we log them in automatically from some state saved the last time the app closed? For Twitter would it work if I just save the auth_token and use it every time the user wants to use twitter from my app? Or do I need to do anything else? I could not get it to work like that so wondering if I was doing something wrong. Thanks.

  • What data should I use to create an autofill "destination" field like Facebook or the Trip Advisor s

    - by sbar
    In order to create a “destination” auto filter input field on our website, I need a data source that provides a hierarchical data set of Region, Country, County/State, City and Town (plus an area like the Peak District National Park if at all possible) I know sites like Trip Advisor and Facebook seem to have very robust datasets for this. When you type, it brings up a match list with the hierarchy displayed (e.g. if you type Boston you get 6 results as there are multiply places called Boston – the hierarchy allows you to pick the correct option) There are many data sources out there but they either lack hierarchy or do not seem to be easily updatable or complete. I had expected this to be an easy task given the amount of site that have a destination or location autofill field. However, i cannot find a datasource or method that works. any help would be much appreciated. Tks,

  • How to implement partial refresh like facebook like/comments?

    - by shillong
    We have java web application. Summary page will display list of rows. For each row, user can vote and add comments. Vote or add comments will commit immediately and refresh total vote number and comments count. We want to refresh current row instead of whole table just like Facebook does. If need, we can show the list of data with form format (iterator List of data) instead of table format. How to implement this feature base on JSF?

  • How to do comments in Activity Stream? (like Facebook)

    - by fesja
    Hi, I'm starting to develop an activity stream. I've read both How to implement the activity stream in a social network and What’s the best manner of implementing a social activity stream?. What I haven't found is the best way to add comments to the activities. As in facebook, each comment can be commented by another person. If each activity comment is saved as another activity, then I would not be able to get the activity of that comment without doing a query. So the solution I'm thinking is to save the comments inside the serialize data field of each activity. If the user wants to delete his comment, I would have to update that activity. Is this the correct solution? Is there a better approach? Thanks!

  • I would like to know how to put a "change image" layer like in facebook on a mouseover event

    - by netadictos
    Hello: I have a photo gallery I would like that every time a user does mouseover the image, there is a button on the top of this image that appears. The user can click on it. But every time that the user mouse out of the photo it must disappear. It works like the "change photo" in Facebook, with the photo of your profile. The problem I am having is that when I try to get over the button that appears (in my code is a link), it disappear because javascript understands that the mouse is just out of the image, even if this button/link is over the image. The image that I use is positioned absolutely over the image. This is my code, where you can see that I create a dom element that I append on the link of the image and then when there is a mouseout, I remove it. $('a.ftelement').mouseover(function() { var fav = $('<a></a>'); fav.attr("class","imgfavorito"); fav.attr("id","fav"+$J(this).attr("id")).html("<img src=\"/im/favorito.gif\"/>"); fav.appendTo(this); }); $('a.ftelement').mouseout(function() { $("a.imgfavorito").remove() }); The result is this graphically (http://www.freeimagehosting.net/uploads/41fbac8994.gif):
