  • How to enable reading non-ascii characters in Servlets

    - by Daziplqa
    How to make the servlet accept non-ascii (Arabian, chines, etc) characters passed from JSPs? I've tried to add the following to top of JSPs: <%@page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> And to add the following in each post/get method in the servlet: request.setCharacterEncoding("UTF-8"); response.setCharacterEncoding("UTF-8"); I've tried to add a Filter that executes the above two statements instead of in the servlet. To be quite honest, these was working in the past, but now it doesn't work anymore. I am using tomcat 5.0.28/6.x.x on JDK1.6 on both Win & Linux boxes.

  • How can I optimize MVC and IIS pipeline to obtain higher speed?

    - by Andy
    Hi, I am doing performance tweaking of a simple app that uses MVC on IIS 7.5. I have a StopWatch starting up in Application_BeginRequest and I take a snapshot at Controller.OnActionExecuting. So I measure the time spend in the entire IIS pipeline: from request receipt to the moment execution finally gets to my controller. I obtain 700 microseconds on my 3GHz quad-core (project compiled Release x64), and I wonder where the bottleneck is, especially hearing some people say that one can get up to 8000 page loads per second with MVC. How can I optimize MVC and IIS pipeline to obtain higher speed?

  • JSON.Stringify data including boolean values

    - by ancdev
    What I'm trying to do is to pass JSON object to a WebAPI ajax call and mapped to a strongly typed object on the server side. String values are being posted perfectly however when it comes to boolean values, they are not being passed at all. Below is my code: var gsGasolineField = $('.gsGasoline').val(); blData = { Gasoline: gsGasolineField }; var json = JSON.stringify(blData); $.ajax({ type: "POST", url: url, data: json, contentType: "application/json", dataType: "json", statusCode: { 201 /*Created"*/: function (data) { $("#BusinessLayerDialog").dialog("close"); ClearForm("#BusinessLayerForm"); }, 400: /*Bad request - validation error*/ function (data) { $("#BusinessLayerForm").validate().form(); }, 500: function (data) { alert('err'); } }, beforeSend: setHeader }); Gasoline property is of type boolean on the server side.

  • How can I make the Rails 3 router localize URLs using localization files?

    - by edgerunner
    What I'd like to be able to do is: in config/routes.rb resources :posts in config/locale/en.yml en: resources: posts: "posts" new: "new" edit: "edit" in config/locale/tr.yml tr: resources: posts: "yazilar" new: "yeni" edit: "duzenle" and get I18n.locale = :en edit_post_path(3) #=> /posts/3/edit I18n.locale = :tr edit_post_path(3) #=> /yazilar/3/duzenle I'd also like Rails to match any of these routes anytime and pass the associated locale in the params hash such that when I navigate to /yazilar , the request should be routed to the posts#index action with the :tr locale in the params hash. Any simple or complex way of doing that?

  • Java Security filter together with thickbox pop-ups

    - by user197127
    Hi, I have a java application that uses a security filter to protect certain resources. If there is no user logged on, it will keep in session the request path and redirect to a logon page. After a successful logon, user is redirected to the original requested page. I have now added some thickbox (ajax bases pop-up) popups to the application. Unfortunately, when I get now a popup that is "secure" the filter redirects to a logon page (which is not a popup) and makes the whole application messy. Anyone with ideas on how to solve this? Thanks

  • How do I retrieve and display html/asp/aspx page on different host using jQuery ajax?

    - by user717236
    I have an html page, which is a dynamically created asp/aspx page on http://host2.mydomain.com. I have no control over the html page. I cannot modify it in any such way. I cannot modify this page; so, setting document.domain is out of the question, unfortunately. I want to retrieve and display this page on http://host1.mydomain.com/page1.jsp using Ajax. FYI: host1 is being served by IIS 7 and Apache Tomcat (for JSP pages). And host2 is using IIS 7 and ASP. How can I retrieve this page using a Ajax POST request? Thank you.

    - by jvcoach23
    I'm using VS 2010, vb.net and asp 3.5. I have a simple default.aspx page that has Dim ctx As HttpContext = HttpContext.Current Dim cookie As HttpCookie = ctx.Request.Cookies("SessionGUID") Me.lbl1.Text = cookie.Value.ToString the page loads fine when running it from within VS, but when i build the site and run the page, it doesn't load.. it doesn't give me an error, but nothing shows up. This is what the view source looks like HTMLHEAD META content="text/html; charset=windows-1252" http-equiv=Content-Type/HEAD BODY/BODY/HTML I took out the < in the tags so that it would display here... If i take out the Me.lbl1.Text = cookie.Value.ToString the page loads fine.. All i'm putting to the page is some text and the label control. anyone have any ideas

  • Hibernate: getting a record but it's being updated in the database?

    - by jack
    For some reason Hibernate seems to be keeping my session open and updating the object without me explicitely invoking a save/update/saveorupdate. I guess the session is staying open and it's beeing marked as dirty. However this is not the desired behaviour, so what's the cleanest way to fix this? The issue seems to occur because I store a phone number without formatting in the database but the getter of the object returns a formatted telephone number. My flow: go to a jsp = controller = service = dao DAO getter function if(userId != 0) { return (User)dbFactory.get(User.class, userId); } return null; The service just passes it to the controller and the controller puts te User object in the request scope. I display it on my JSP page using EL.

  • In Node.JS, how do I return an entire object from a separate .js file?

    - by Matthew Patrick Cashatt
    Thanks for looking. I am new to Node.js and trying to figure out how to request an object from a separate file (rather than just requesting a function) but everything I try--exports,module-exports,etc--is failing. So, for example, if I have foo.js: var methods = { Foobar:{ getFoo: function(){return "foo!!";}, getBar: function(){return "bar!!";} } }; And now I want to call a function within an object of foo.js from index.js: var m = require('./Methods'); function fooMain(){ return m.Foobar.getFoo(); }; How do I do this? I have tried all sorts of combinations of exports and module-exports but they seem to only work if I call a discrete function that is not part of an object. Thanks!

  • Sum in shell script

  • What is the current standard for authenticating Http requests (REST, Xml over Http)?

    - by CodeToGlory
    The standard should solve the following Authentication challenges like- Replay attacks Man in the Middle Plaintext attacks Dictionary attacks Brute force attacks Spoofing by counterfeit servers I have already looked at Amazon Web Services and that is one possibility. More importantly there seems to be two most common approaches: Use apiKey which is encoded in a similar fashion like AWS but is a post parameter to a request Use Http AuthenticationHeader and use a similar signature like AWS. Signature is typically obtained by signing a date stamp with an encrypted shared secret. This signature is therefore passed either as an apiKey or in the Http AuthenticationHeader. I would like to know weigh both the options from the community, who may have used one or more and would also like to explore other options that I am not considering. I would also use HTTPS to secure my services.

  • does a ruby on rails rack class get access to the entire rails environment?

    - by Andrew Arrow
    that is when the def call(env) method is invoked by hitting any url, can I inside that method make some ActiveRecord queries, use classes defined in lib, etc. etc. Or is it more like an irb console without the rails env loaded? Another way to put it with a rake task example: task :foo => :environment do # with env end task :foo2 do # without env end I would think rack classes would NOT get the environment so they are super fast and don't take all the overhead of a normal rails request. But that doesn't seem to be the case. I CAN make ActiveRecord queries inside my rack class. So what is the advantage of rack then?

  • Encoding with url and api

    - by user2950824
    So I have this web app set up and running and it works fine for any username that you request, but when i try http://mrcastelo.pythonanywhere.com/lol/euw/Nazaré, it simply doesnt work - the error that I get on the server is the following: iddata= getJSON(urllolbase+region+urlid+username) #SummonerID UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 5: ordinal not in range(128) It is annoying me greatly, I've tried some other threads but none of them came to a fix. The api that I am using (www.legendaryapi.com) does accept this because this works. Any idea on how to fix this?

  • Can Google App Engine be used for "check for updated" and download binary file web service?

    - by Tofrizer
    Hi, I'm a Google App Engine newbie and would be grateful for any help. I have an iPhone app which sources data from an sqlite db stored localling on the device. I'd like to set up a Google App Engine web service which my iPhone client will talk to and check if there is a newer version of the sqlite database it needs to download. So iPhone client hits the web service with some kind of version number/timestamp and if there is a newer file, the App Engine will notify the client and the client will then request the new database to download which the App Engine will serve. Is it possible to set up a web service in Google App Engine to do this? Could anyone point me to any sample code / tutorials please? Many Thanks

  • Auto save changed text in richtextbox to database

    - by user2519407
    I have created one simple note taking application in jquery & php. Current functionality is like when user clicks save button it sends a ajax request with complete data to update it in db(mysql). All works well. But now I want to auto save only changed text while user typing. I don't want to send entire text to server again and again in text change event. It should send only text which has changed. For Ex: This is saved text. When user continues typing. This is saved text. Unsaved text.. It should be able to send only "Unsaved text.." to server to update in db. How can i implement this in jquery & server side script.? Any Idea..?

  • How to ensure YouTube API only returns videos that are playable on iPhone?

    - by prendio2
    I'm building some YouTube search functionality into an iPhone app and want to ensure that I only receive results that will be playable on the device. According to the Searching for videos section in the API reference doc this seems to be relatively straightforward: The format parameter specifies that videos must be available in a particular video format. Your request can specify any of the following formats: I've currently set my project to only return videos with "format=1" which will limit to: RTSP streaming URL for mobile video playback. H.263 video (up to 176x144) and AMR audio. I'd love if someone could confirm that this is in fact the appropriate setting or let me know if I'm missing something. Cheers.

  • Advanced queries in HBase

    - by Teflon Ted
    Given the following HBase schema scenario (from the official FAQ)... How would you design an Hbase table for many-to-many association between two entities, for example Student and Course? I would define two tables: Student: student id student data (name, address, ...) courses (use course ids as column qualifiers here) Course: course id course data (name, syllabus, ...) students (use student ids as column qualifiers here) This schema gives you fast access to the queries, show all classes for a student (student table, courses family), or all students for a class (courses table, students family). How would you satisfy the request: "Give me all the students that share at least two courses in common"? Can you build a "query" in HBase that will return that set, or do you have to retrieve all the pertinent data and crunch it yourself in code?

  • Detecting regional settings (List Separator) from web

    - by Toms Mikoss
    After having the unpleasant surprise that Comma Seperated Value (CSV) files are not necessarily comma-separated, I'm trying to find out if there is any way to detect what the regional settings list separator value is on the client machine from http request. Scenario is as follows: A user can download some data in CSV format from web site (RoR, if it matters). That CSV file is generated on the fly, sent to the user, and most of the time double-clicked and opened in MS Excel on Windows machine at the destination. Now, if the user has ',' set as the list separator, the data is properly arranged in columns, but if any other separator (';' is widely used here) is set, it all just gets thrown into a single column. So, is there any way to detect what separator is used on the client machine, and generate the file accordingly? I have a sinking feeling that it is not, but I'd like to be sure before I pass the 'can't be done, sorry' line to the customer :)

  • Validate XML instance document against WSDL

    - by Ice09
    Hi, I can easily validate a XML document against a XML Schema, eg. with XMLSpy or programmatically. Is it possible to do this with a WSDL file? It does not seem possible with XMLSpy or any other XML tool I know. For me the only possibility right now is to do it programmatically, eg. by generating Java code from the WSDL and starting a request, which is then marshalled correctly. If there is no tool / easy programmatic approach, is there a tool which can extract XML Schema from the WSDL? Best

  • Convert Google results object (pure js) to Python object

    - by colwilson
    So I'm trying to use Google Map suggest API to request place name suggestions. Unfortunately I can't find the docs for this bit. Here is an example URI: http://maps.google.com/maps/suggest?q=lon&cp=3&ll=55.0,-3.5&spn=11.9,1.2&hl=en&gl=uk&v=2 which returns: {suggestion:[{query:"London",... I want to use this in python (2.5). Now in proper JSON there would have been quotations around the keys like so: {"suggestion":[{"query":"London",... and I could have used simplejson or something, but as it is I'm a bit stuck. There are two possible solutions here; either I can get to the API code and find an option to return proper JSON, or I do that in python. Any ideas please.
