  • getHeaderField("WWW-Authenticate") giving improper value in J2ME

    - by kehers
    I'm building a client for an api that uses http digest access authentication for authentication. I have studied the rfc to know the setup the required response headers and this works well on my emulator. Problem however is when I test on my phone (nokia E5), I found out that getting the www-authenticate header from the returned headers doesnt get the full value [code] // c = (HttpConnection) Connector.open(url) and other declarations String digest = c.getHeaderField("WWW-Authenticate"); System.out.println(digest); // gives only: Digest //no realm, qop and others [/code] I'm I doing something wrong or it is from the phone? What are my other options?

  • Simple Java library for storing statistical observations and calculating statistics such as stddev,

    - by knorv
    For logging purposes I want to collect the response times of an external system, and periodically fetch various statistics (such as min/max/stddev) of the response times. I'm looking for a pure in-memory solution. What Java library can help me with this simple task? I'm looking for an API that would ideally look something along the lines of: StatisticsCollector s = new StatisticsCollector(); while (...) { double responseTime = ...; s.addObservation(responseTime); } double stddev = s.getStandardDeviation(); double mean = s.getMean();

  • Java Thread wait() => blocked?

    - by Chris
    According to http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Thread.State.html calling wait() will result a thread to go in BLOCKED state. However this piece of code will result (after being called) in a Thread in WAITING State. class bThread extends Thread { public synchronized void run() { try { wait(); } catch (InterruptedException e) { e.printStackTrace(); } } } Have I got something wrong? Can anybody explain this behaviour to me? Any help would be appreciated!

  • If I write a framework that gets information from the Internet, should I make a degelate or use blocks?

    - by Time Machine
    Say I'm writing a publicly available framework for the Vimeo API. This framework needs to get information from the Internet. Because this can take some time, I need to use threadin to prevent the UI from hanging. Foundation uses delegates for this, like NSURLConnectionDelegate. However, Game Kit uses blocks as callback functions. What is the recommended way of doing this? I know blocks aren't supported in standard GCC versions, but they require less, much less code for the one that uses my framework. Delegates, on the other hand, are real methods and when protocols are used, I'm sure the methods are implemented. Thanks.

    - by Myat
    I have three models User, Activity and ActivityRecord. class User < ActiveRecord::Base # Include default devise modules.

    - by tomaszsobczak
    Hi, I want to know number of rows that will be affected by UPDATE query in BEFORE per statement trigger . Is that possible? The problem is that i want to allow only queries that will update up to 4 rows. If affected rows count is 5 or more i want to raise error. I don't want to do this in code because i need this check on db level. Is this at all possible? Thanks in advance for any clues on that

  • Is there any way around the Chrome 5 breakage of Ajax for local files?

    - by nikow
    The recent Chrome 5.0 release completely blocks XMLHTTPRequest requests for local files comming from a local file. Here is just one of the many related bug reports and here is the code change (there is also a SO question caused by this). This breaks a lot of production code, e.g. for documentation systems. Users must be able to browse local documentation without the need to install anything or run executables. My question is if there is any way around this restriction? I'm only interested in solutions that don't require any fancy actions on the users side (nothing beyond a confirmation dialog). Is there any way the HTML5 File API could be used, or maybe postMessage()? Of course this whole issue is very frustrating for many people. Firefox takes a fare more reasonable approach and allows requests inside the directory. So it seems unlikely that other browser vendors will follow Chrome.

  • require user to login in at login screen before giving access to iPhone app that accesses secure web

    - by MikeN
    On iPhone, how do I show a login screen to get username and password before giving access to iPhone app? Also, does the iPhone store a cookie to the secure website like a web browser? I was thinking of giving users to my website a long API key to store in the settings of their iPhone instead of asking them to login with a username/password (seems to be the Slicehost iPhone app approach.) Which is the best way to get a user to login securely? I have full control over the design of the iPhone app and website so have a lot of flexibility.

  • J2ME linking interfaces.

    - by user554031
    Hey guys, I've been working with J2ME for a short while, however I've been unable to find anything regarding my query. I'm wanting to link interfaces, I.E A to B to C. Similar to a card layout. Information on each interface changes based on the choices the user made previously. For example City - Cinema - Cinema Listings. The eventual target is to create a MIDlet that displays information from a database (I understand a midlet needs to connect to a servlet which connects to the DB). Thanks in advance for you're time.

  • Restful client on Codeigniter issue

    - by user1852837
    This is weird. I don't know what is problem on my website. My website works on local server but not on live server. Login page works on first signin but after logout then re-login again message says: "invalid username and password" since it works on first attempt. I found out when I debugging that http://xxxxx.com/api/authentication/sign not found. It display 404 page not found. Sometimes you can login and sometimes not. In my local it works. I contact the web server admin and I ask what is the status of the session on the server and How does it execute it's web requests? (Sockets, file_get_contents, curl?). They said that No problems reproduced with Server Sessions and PHP Curl works fine. I know it's weird but can somebody here can figure it out what is the problem behind of it.

  • SQL Server 2008. Allow Remote Connections?

    - by George
    I have SQL Server 2000 and 2008 installed on a Windows XP Pro box. I can connect to both db instances locally. From another box, a Windows 7 box, I can connect to the SQL 2000 instance on the first box but I cannot connect to the 2008 instance using the same SQL Server authentication credentials that worked locally. Allow Remote Connections is set to TRUE for both the 2000 and 2008 database instances. What else can I look for to be able to connect to the remote 2008 instance from the Windows 7 box? I am trying to connect using Mgt Studio 2008.

  • How to remember last state with Jquery?

    - by AR
    I have a menu with submenus that can be toggled (hide/show type deal). Is there a relatively easy way to remember last state of the menu? (I hide/show submenu when clicking on a header and change a style of the header so the background arrow will change (up/down)). It works fine, but I'd like it to remember last state, so when user goes to another page on the site and gets back, the menu shows the same way as user left it. I'm not really good with cookies so any help will be appreciated. Yeah, menu is generated dynamically from the db using PHP. There are now only 2 headers with submenus, but there will be more so I'd need some method that's "scalable" for any number of submenus. There is also no need to remember it for longer then one visit. Current url is this: http://valleyofgeysers.com/geysers.php

  • Where is the best place to store globals in Rails app?

    - by Nick Gorbikoff
    Hello. I was wondering if there is the best practice on where to store global settings in a rails app. What I mean by that is i.e: I have a few globals defined that may change, but not likely and it seems inappropriate to store them in DB since they are used so much. For instance I have SYSTEM_EMAIL & SYSTEM_EMAIL_SIGNATURE & SYSTEM_STORAGE_ROOT. Right now I keep them in environment.rb, but I'm not sure if this is the right palce to store them. Thank you

  • Cant handle it (jQuery hanlder understanding needed)

    - by chainwork
    I'm embarrassed to even ask BUT could someone help me understand what a "handler" is. I am new to jQuery and the API constantly has references similar to the following: toggle( handler(eventObject), handler(eventObject), [ handler(eventObject) ] ) I scratch my head and say to myself "what the hell is a handler". Then I check my 2 jquery books and don't really see anything specific there. I get what an event handler does, it handles an event. But the word handler in the above context confuses me including "eventObject". I tried to google it but could not really find a really clear definition of what exactly a handler is as it relates to jquery. Thanks for your help =]

  • Rails - column not found for defined 'has_many' relationship

    - by Guanlun
    I define a Post class which can link or be linked to multiple posts. To do this I added a PostLink class which specifies post_to and post_from. I generated the PostLink class by rails g model post_link from_post:integer to_post:integer and of course rake db:migrate, and added belongs_to :from_post, :class_name => 'Post' belongs_to :to_post, :class_name => 'Post' to the class. And I also have has_many :post_links in my Post class. I ran rails console and Post.new.post_links and got nil printed out, which is expected. However after I save a Post using p = Post.new p.save and then run p.post_links, it prints out the following error message: SQLite3::SQLException: no such column: post_links.post_id: SELECT "post_links".* FROM "post_links" WHERE "post_links"."post_id" = 1 So anybody know why after saving it to the database post_link can not be accessed?

  • Rails: User specific sequential column

    - by Alex Marchant
    I have an inventory system, where a User has many inventory. We have a barcode column which needs to be sequential for each user. I run into a problem however when doing bulk association building. I end up getting several inventories for a user with the same barcode. For example: Inventory Table: id | user_id | barcode 1 | 1 | 1 2 | 1 | 2 3 | 2 | 1 4 | 2 | 2 5 | 1 | 3 In the Inventory model I have before_validation :assign_barcode, on: :create def assign_barcode self.barcode = (user.inventories.order(barcode: :desc).first.try(:barcode) || 0) + 1 end It generally works, but ran into a problem when seeding my db: (1..5).each do user.inventories.build(...) end user.save I end up with a bunch of inventories for user that have the same barcode. How can I ensure that inventories have unique barcodes even when adding inventories in bulk?

  • I can't upload a file with CGIHTTPServer

    - by sdemingo
    Hi all, I'm using the CGIHTTPServer to implement a simple cgi server. I'm trying to upload a file by a form with the post method and the multipart/form-data enctype but I have problems when I recover the value of the fields in the cgi script. When the script catch the form fields, the value of the file is a MiniFieldStorage with two fields only (key and file name), and I can't recover the content of the file. As the API doc shows, this content is in value field of a StorageField but in the MiniFieldStorage this field isn't exits. ¿How can I recover a StorageField with the content of the file instead a MiniStorageField? ¿There are other method to upload a file using CGIHTTPServer? Thanks a lot

  • Determining smallest number of samples for 99% accuracy

    - by test
    I'm trying to compare 100,000 records on a local database (L) with 100,000 records on a remote database (R). Basically I want to know if an elment in L exusts in R. To determine that, I have to make a request against the R for each L, which takes a long time (I know, there should be a better way, there isn't, that's the API I've got). So I would like to test a small sample of L against R, and then infer with some level of confidence how many are present in the whole R. How many do I have to test to have a 99% confidence level?
