What can I do to see changes in my Java code immediately in the browser?

• Inserting variable into routes - map.resources :posts, :as => X - is this possible?

  - by bgadoci

  Ok, so I am working on a blog application of sorts. Thus far, it allows for a user to sign up for their own account, create posts, tags, comments, etc. I have just implemented the ability to use www.myapp.com/brandon to set @user to find by username and therefore correctly display the users information at each url. So when you go to www.myapp.com/brandon you see all Brandon's posts, tags, and comments associated with those posts, etc. Works great. I'm implementing this URL mapping through the routes.rb file by adding the following: map.username_link '/:username', :controller => 'posts', :action => 'index' And then just setting the @user variable in the PostController and corresponding views to find_by_username. Now the issue is this. Once at www.myapp.com/brandon when you click on a post title, it sends to myapp.com/posts/id without the username in the URL. How do I tell rails to replace the /posts with /username. Is it even possible to insert the user_username variable into this code? map.resources :posts, :as => [what goes here]

• PHP XML Validation

  - by efritz

  What's the best way to validate an XML file (or a portion of it) against multiple XSD files? For example, I have the following schema for a configuration loader: <xsd:schema xmlns="http://www.kauriproject.org/schema/configuration" xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.kauriproject.org/schema/configuration" elementFormDefault="qualified"> <xsd:element name="configuration" type="configuration" /> <xsd:complexType name="configuration"> <xsd:choice maxOccurs="unbounded"> <xsd:element name="import" type="import" minOccurs="0" maxOccurs="unbounded" /> <xsd:element name="section" type="section" /> </xsd:choice> </xsd:complexType> <xsd:complexType name="section"> <xsd:sequence> <xsd:any minOccurs="0" maxOccurs="unbounded" processContents="lax" /> </xsd:sequence> <xsd:attribute name="name" type="xsd:string" use="required" /> <xsd:attribute name="type" type="xsd:string" use="required" /> </xsd:complexType> <xsd:complexType name="import" mixed="true"> <xsd:attribute name="resource" type="xsd:string" /> </xsd:complexType> </xsd:schema> As the Configuration class exists now, it lets one add a <section> tag with a define concrete parser class (much like custom configuration sections in ASP.NET). However, I'm unsure of how to validate the section being parsed. If it possible to validate just this section of code with an XSD file/string without writing it back to a file?

• How to deploy a Java web application? [closed]

  - by Yatendra Goel

  I have developed a Java Web Application and I want to show it to my client by hosting it on a server. I tried to run it on my localpc through web-browser and it worked fine. I gave the hostname as "localhost" in the URL of my webApplication. Now I want to show it to my client who is on other computer on internet. I tried to replace the "localhost" from my webApplication's url to my current ip address. But when I put that URL on my own browser, it didn't work. How can I show that web-application to my client. I have my own domain name but do not own any web-hosting. I don't want to purchase a web-hosting plan. One more problem: I don't have static IP address. My IP changes almost everytime when I connect to my ISP.

• Back button loop with IFRAMES

  - by Tim Jackson

  In my (school) website we use Iframes to display class blogs (on blogger). This works well EXCEPT if the user then clicks on (say) a photo inside the iframe. Blogger (in this case) then displays the photo in the whole browser window and the back button loops; that is if the back button is hit, the browser (IE, FF, Chrome) stays on the same page. The only way out is for the user to jump back two pages (which many of our users don't know how to do). I've read a lot of posts on back buttons and iframes and there doesn't appear to be a simple solution. Bear in mind that I don't have control over the iframe content (so no embedded back buttons in the frame are possible). Ideas anyone?

• Unsupported operand types when value is integer

  - by Adam Tester

  I'm getting this error when trying to add 2 to an integer. I am using the Codeigniter framework. Fatal error: Unsupported operand types in D:\wamp\www\application\libraries\Gen_images.php on line 180 Here is where its called: // Now process the image var_dump($this->upload->data('image_width')); $this->gen_login->resize($file_name, $this->upload->data('image_width'), $this->upload->data('image_height')); I get the error on line 180 which is: $config['width'] = $width + 2; So I thought $width must be an array or string so I wouldn't be able to add to it, but the var dump shows this: array 'file_name' => string 'genyx_1341414096.jpg' (length=20) 'file_type' => string 'image/jpeg' (length=10) 'file_path' => string 'D:/wamp/www/beer/uploads/' (length=25) 'full_path' => string 'D:/wamp/www/beer/uploads/genyx_1341414096.jpg' (length=45) 'raw_name' => string 'genyx_1341414096' (length=16) 'orig_name' => string 'genyx_1341414096.jpg' (length=20) 'client_name' => string '294207_177080222375077_100002193022560_361510_991268937_s.jpg' (length=61) 'file_ext' => string '.jpg' (length=4) 'file_size' => float 55.85 'is_image' => boolean true 'image_width' => int 720 'image_height' => int 479 'image_type' => string 'jpeg' (length=4) 'image_size_str' => string 'width="720" height="479"' (length=24) Can anyone help me?

• How do I position an element so that it acts like both 'absolutely' & 'relatively' positioned at the same time? - CSS

  - by marcamillion

  You can see the implementation here: http://jsfiddle.net/BMWZd/25/ When you click on one of the names in Box#1, you will see the circle in the top left corner of the box move up and down. How do I stop that? While also, making sure that it shows in the top left corner of each of the boxes on all browser sizes? So position:absolute will keep it in one place regardless of what happens around it. But it won't put it in the exact same position (relatively) on diff browser sizes. But position:relative will. How do I get the best of both worlds?

• Javascript onbeforeunload Issue

  - by Nik

  Alright, I have an issue with the following code. What happens is when a user closes their browser, it should prompt them to either click OK or click CANCEL to leave the page. Clicking OK would trigger a window.location to redirect to another page for user tracking (and yes, to avoid flame wars, there is a secondary system in place to assure accurate tracking, in the event of the user killing the browser from the task manager (as mentioned in similar questions)). CANCEL would remain on the page, the issue being that no matter what button you hit, you get redirected as if you wanted to leave the page. The relevant code is below. window.onbeforeunload = confirmExit; function confirmExit() { var where_to = confirm("Click OK to exit, Click CANCEL to stay."); if (where_to == true) { window.location="logout.php"; } if (where_to == false){ alert("Returning..."); } }

• Establish context with Watin

  - by Ian Quigley

  Feel free to tell me I'm doing this wrong but... I have the Watin attribute [Browser("IE")] and want to extend this attribute so that it will perform an action (login) to establish the context for the test (setup). I've created public class LoggedInBrowserAttribute : BrowserAttribute which takes URL, username, password and performs the login steps. However, if for some reason the username/password won't login to the system I don't want to perform the test. In the GetBrowser method I'm doing an Assert (is logged in) which seems wrong. What is the correct way to establish this context / abort the test? I don't want to return null from GetBrowser and then have if (browser == null) at the top of my test.

• A PHP script to stream internet radio?

  - by Honus Wagner

  I've been searching and searching and I haven't yet come up with a solution to host my own streaming audio player. I'm looking for a way to host an internet radio player that connects to whatever streams I enter in and plays them. I'm not looking to play my MP3s or anything like that. I'm looking to play content from 181.fm or 1Club.fm, for example. I'd even settle for ShoutCast-only streams. I've been to www.wavestreaming.com but it didnt work for me. I'm guessing its because in the very first box where you enter your website url, it leads in for you: http//www. then you fill in the rest. My site is https:// and does not contain a www. in the URL. I'm guessing that has something to do with it. Any links, suggestions for search topics, or even a brief technical overview of what I should be looking into would be greatly appreciated. Thanks for your time.

• OData / WCF Data Service - HTTP 500 Error

  - by Eric

  I have created an OData/WCF service using Visual Studio 2010 on Windows XP SP3 with all current patches installed. When I click on "view in browser", the service opens and I see the 3 tables from my EF model. However, when I add a table name ("Commands" in this case) to the end of the query string, rather than seeing the data from the table, I get an HTTP 500 error. (This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.). I have not only followed the examples from 2 sites, but have also tried running the sample application that the blog poster sent me (that works on his machine), and still am not having any luck. The blog post is at Exposing OData from an Entity Framework Model Does anyone have an idea why this is occurring and how to resolve it? Here is the output of the "View in Browser": <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:1883/VistaDBCommandService.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> - <collection href="Commands"> <atom:title>Commands</atom:title> </collection> - <collection href="Databases"> <atom:title>Databases</atom:title> </collection> - <collection href="Statuses"> <atom:title>Statuses</atom:title> </collection> </workspace> </service> ============================= Thanks, Eric

• Agile and Scrum burning me down please help me figuring out the truth

  - by jadook

  hi all, in the last while I installed MS-TFS 2008 then started to get myself prepared to use Agile Process Guidance template shipped with the TFS. with little googling I passed through Mike Cohn materials: I watched his conference in youtube "sponsored by google: http://www.youtube.com/watch?v=fb9Rzyi8b90 http://www.youtube.com/watch?v=jeT0pOVg0EI Read his book "Agile Estimating and Planning" Watching the video series in his website: http://www.mountaingoatsoftware.com/presentations-tag/video-recorded I was very happy while absorbing and eating the techniques he is using with the teams and how agile and scrum is such a great software process/methodology until I saw Mike answering a question regarding an architect role and talking about the requirements document... at that point everything start falling apart due to the following: Last year I had been assigned to make full analysis "including requirements gathering" for big project "very high priority project". within 2 months of hardwork, dedication and commitment I delivered the whole analysis with full satisfaction of the customer and my BOSS and ZERO amendments. Later on, the project entered the architecting, development ... phases. due to the fact that the system included many competitive and exciting features I requested patenting it and its going in the process... so imagine you are the kind of person who used to love facing all kind of challenges and returning with excellent experience and results for the stakeholders and yourself, How fairly agile and scrum processes will credit and admit your talent and passion while the scrum master/coach treat the team as one unit that accomplish user stories and converge through trial and error approach??!!!! with that dark thoughts about agile and scrum I found many people "anti agile" and on top of them is "Crispin Rogers Johnson": http://agile-crispin.blogspot.com/ that guy made anti statement for everything Mike Cohn used to talk about. I really don't know what to do next! so any guidance will be appreciated. Thanks,

• IMetadataExchange endpoint purpose

  - by Paresh.Bijvani

  What is the purpose of IMetadataExchange endpoint. Some places i found that if i dont define this endpoint, adding service reference will not work OR creating proxy using svcutil wont work. But both of this working without having IMetadataExchange defined. If we have other endpoint with httpGetEnabled = true, we are able to create proxy from client. Also, some article says that we should delete IMetadataExchange before moving code to production and it should development period only so that other client cant see metadata. Doesnt this stop the behaviour of service having self describing itself? And if I have defined this IMetadataExchange endpoint, how can i see that on browser. Address whoch i have provided for this endpoint is not pulling any metadata in browser.

• Debugging asp.net with firefox and visual studio.net - very slow compared to IE

  - by john

  Debugging asp.net websites/web projects in visual studio.net 2005 with Firefox is loads slower than using IE. I've read something somewhere that there is a way of fixing this but i can't for the life of me find it again. Does anyone know what i'm on about and can point me in the right direction please? Cheers John edit sorry rob i haven't explained myself very well(again). I prefer Firefox for debugging (firebug etc) hitting F5 when debugging with IE the browser launches really quickly and clicking around my web application is almost instant and when a breakpont is hit i get to my code straight away with no delays. hitting F5 when debugging with FireFox the browser launches really slowly (ok i have plugins that slow FF loading) but clicking around my web application is really really slow and when a breakpoint is hit it takes ages to break into code. i swear i've read something somewhere that there is a setting in Firefox (about:config maybe?) that when changed to some magic setting sorts all this out.

• IE9 syntax on jquery crossbrowser with jsonp and FF, Chrome

  - by Andrew Walker

  I have the following code and i have a problem in ensuring part of it is used when a IE browser is used, and remove it when any other browser is used: $.ajax({ url: 'http://mapit.mysociety.org/areas/'+ulo, type: 'GET', cache: false, crossDomain: true, dataType: 'jsonp', success: function(response) { This works fine in IE9 because I have put the dataType as jsonp. But this will not work on Chrome or FF. So I need to remove the dataType. I tried this: <!--[IF IE]> dataType: 'jsonp', <![endif]--> But it did not work. It's worth noting, it does not need the dataType set when in FF or Chrome as it's json. Whats the correct syntax to have this work ? Thanks Andrew

• Firefox session cookies

  - by meandmycode

  Generally speaking, when given a cookie that has no expiration period, modern browsers will consider this cookie to be a 'session cookie', they will remove the cookie at the end of the browsing session (generally when the browser instance closes). IE, Opera, Safari and Chrome all support this behavior. However firefox (3.0.9 latest proper release) appears not to follow this rule, from what I can tell it doesn't expire the cookies when the browser is closed, or when the user logs off or restarts the OS.. So, why does firefox refer to these as session cookies, when they last aparently indefinitely? Does anyone know how Firefox handles session cookie expiration?

• Getting started with Windows Azure

  - by jonhobbs

  Hi All, I'm going to sound like a complete newbie here but here goes... I've just signed up for a Windows Azure account and was hoping to get a simple hello world aspx page up and running in a browser to see how it all works but I can't seem to find a simple guide to getting a very simple web application running. I've got as far as setting up a "service" and going onto the "deploy" page but it's asking me upload an "application package". I've looked on MSDN but there aren't any simple guides, just reams of documentation talking about "roles" and "development fabric". For somebody that is proficient in HTML/CSS and knows a little abit about asp.net it may just as well be in another language. So, does anybody know how to upload a simple aspx page and then access it in a browser? Jon
