• Why can't I access a web app running on my Mac via my iPhone?

  - by bpapa

  I'm developing an iPhone app that has a network component. I'm developing the app in Java (Google App Engine actually), running on port 8080. And it works, when I test my app in the iPhone simulator. But now I am trying to test on the device, and I can't hit my Jetty instance. I can certainly access my Mac via the iPhone because I'm able to hit http://10.0.1.7/~brianpapa/ and view my Home Folder when Web Sharing is turned on. But when I try to hit http://10.0.1.7:8080/, it says it can't connect to the server. Interestingly, if I try to hit http://10.0.1.7:8080/ from my mac, it doesn't work either - I have to use localhost as the hostname instead, then it's fine. Has anybody ever encountered this before, and know how to fix it?

• Silverlight, Flash, or JavaScript for web app that runs client-side, or just stick with C#?

  - by Sootah

  Silverlight, Flash, and JavaScript, oh my.. I have a couple of applications that I need to develop for one of my business partners that will be distributed to dozens of people. These applications will need to be able to query information from the internet (query via Google, grab feeds from our other sites, just general web access) and save files to their computer. The reason I want to host the application is so that it all can be centrally managed, and any updates would be instantly deployed to everyone that uses the service. There always seems to be headaches with developing a pure desktop app in a language like C# with regards to making sure people use the latest version, don't have some odd problem with the installer, etc. Since we don't want to tie up our server's CPU I want effectively all of the processing done client-side. Meaning that they would log into their account, access the app, and then all the work done within the app is all handled by their machine. Only specific data would be sent back to the server. So - which language is best for this? Microsoft's Silverlight, Adobe's Flash, or Sun's JavaScript? I've heard a lot of good things about Silverlight and have wanted to try it for some time. I've only done extremely limited JavaScript programming, and absolutely none with Flash. Or, with my main requirement being that the client does all of its own processing should I just stick with C#? Also, is there any way to integrate a C# app into a webpage? I've never even considered it (or have any idea if it's even possible) until just now. Thanks in advance! -Sootah

• How to read a (SharePoint) custom web part property before the page loads?

  - by Josh

  I have a custom web part in SharePoint that has one property. Here is it: // Specify report path private string _report_path = string.Empty; [WebBrowsable(true), Personalizable(true), WebDisplayName("Enter Path"), WebDescription("Embeds an OBIEE Report in the portal"), SPWebCategoryName("Report")] public string ReportPath { get { return _report_path; } set { _report_path = value; } } The problem is that, I have to refresh the page manually a second time for the property to get set. Apparently, I need to put the method inside a PreRender event. Does anyone know how I can do this? Thanks.

• Can a signed Java Applet/Web Start manipulate content in a cross-site IFRAME?

  - by etoleb

  Is it possible for a signed Java Applet or Web Start app to write to the DOM of an IFRAME under a different domain? Does the fact that they're a signed applet/javaws allow them to ignore browsers' standard cross-browser security? If this does work, how well is it supported across the major browsers? Thanks! EDIT: My motivation is to add a browser plugin-like tool to third-party websites I don't control. It's not required that I use Java at all---any ideas or suggestions are encouraged.

• What are the pros/cons to these 2 ways of defining parameters for a web service method

  - by Antony Scott

  I have an existing web service I need to expand, but it has not gone into production yet. So, I am free to change the contracts as I see fit. But I am not sure of the best way to define the methods. I am leaning towards Method 2 for no other reason than I cannot think of good names to give the parameters classes! Are there any major disadvantages to using Method 2 over Method 1? Method 1 [DataContract(Namespace = Constants.ServiceNamespace)] public class MyParameters { [DataMember(Order = 1, IsRequired = true)] public int CompanyID { get; set; } [DataMember(Order = 2, IsRequired = true)] public string Filter { get; set; } } [ServiceContract(Namespace = Constants.ServiceNamespace)] public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(MyParameters params); } Method 2 public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(int companyID, string filter); }

• How do you set up your web server & document's html to correctly serve HTML5 documents?

  - by joedevon

  Maybe I'm an idiot but I don't quite get what goes in the header of my HTML to use XHTML w/ HTML5. Is this still good and we just add the HTML5 tags?: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html dir="ltr" lang="eng" xmlns="http://www.w3.org/1999/xhtml"> Or is it <!DOCTYPE html> or what? Then at A List Apart they say: If you do go with XHTML 5, remember that your server must deliver the documents with a MIME type of application/xhtml+xml or text/xml. Please explain to me as if I was stupid :) what that means in a practical sense? "deliver the documents"? Meaning html? What happens to php? What are the steps required to set up your web server this way?

• How do I tell which account is trying to access an ASP.NET web service?

  - by Andrew Lewis

  I'm getting a 401 (access denied) calling a method on an internal web service. I'm calling it from an ASP.NET page on our company intranet. I've checked all the configuration and it should be using integrated security with an account that has access to that service, but I'm trying to figure out how to confirm which account it's connecting under. Unfortunately I can't debug the code on the production network. In our dev environment everything is working fine. I know there has to be a difference in the settings, but I'm at a loss with where to start. Any recommendations?

• Do Url shorteners such as bit.ly serve any purpose in web development?

  - by gath

  I might be missing something here but am unable to understand the true purpose of link shortener services like bit.ly or is it just a lot of hype! Truly if you type nyti.ms on your URL bar on the browser it takes you to www.nytimes.com, but still what is so hard in typing "nytimes.com! which is far much comprehensible to read and understand leave alone to remember! Does shortening URL serve any purpose in web development? Why should someone want use obscure shortened URL?

• Are there any OSGi web service / SOAP clients out there?

  - by James Carr

  I'm looking for any webservice client that can be run inside an OSGi container and connect to a simple web service using SOAP, doesn't sound so hard does it? Oh, and it has to work under Java 1.5, so the JRE jax-ws wont be present. The problem is I've tried a few solutions now, and although each solution works in standard Java using it from within OSGi doesn't. the springsource JAX-WS bundles seem to have dependency issues the CXF bundles get me as far as calling the service, but then can seem to find the stub methods in the proxy Is there anyone out there who has successfully created an OSGi webservice client?

• Do people create and use Web Parts connections?

  - by Javaman59

  I've been writing some SharePoint web parts wich connect (as providers and consumers). I've found many difficulties, and (comparatively*) little material from the web, from books, or from microsoft.com, which is quite surprising as Web Parts have been around since 2003. This is making me think that although web part connections look like a first class feature in SharePoint, that in practice few people write connecting web parts, and few SharePoint users use them. Is this the case - that few developers write connecting web parts, and few users use them? *comparitively: A subjective impression. With each specific problem i usually find only a handful of web pages which address it, and as my problems seem to be fundamental ones (such which data type to wrap in an IWebPartRow), I expect a lot more search results.

• Missing on-screen keyboard for Flash/Flex web application on Android?

  - by HDave

  I have an enterprise Flex web application, served up over https, that runs fine on Flash player 10.0 and beyond from a desktop computer/browser. However, when I run it from my HTC Incredible with Android 2.2 the app loads fine, but there is no on-screen keyboard and so I cannot log in. I can see the blinking cursor inside the username and password text fields. I can switch between them. I can even hit the login button and see an authentication error! According to Adobe this should Just Work. Any ideas? I wanna show off our spanking new app to strangers at the bus stop!

• BDD-testing using a UI driver (e.g. Selenium for a web-application)

  - by jonathanconway

  Can BDD (Behavior Driven Design) tests be implemented using a UI driver? For example, given a web application, instead of: Writing tests for the back-end, and then more tests in Javascript for the front-end Should I: Write the tests as Selenium macros, which simulate mouse-clicks, etc in the actual browser? The advantages I see in doing it this way are: The tests are written in one language, rather than several They're focussed on the UI, which gets developers thinking outside-in They run in the real execution environment (the browser), which allows us to Test different browsers Test different servers Get insight into real-world performance Thoughts?

• Products combining framework and visual IDE for web development?

  - by Tom Hubbard

  We are looking for some tools to help us with our web development speed. The two main areas that we have pinpointed as parts of the problem are "Framework/Flow Management" and "Visual/Layout Development" Ideally we would find a tool that handles both rather well. However, it seems like there are few tools that handle the middle ground well. Usually it is just a Framework, or and IDE, not both. The best thing we have found so far is Agile Platform. Are we missing any obvious products? Platform at this point is not a huge concern. We can migrate to the best tool.

• How do you determine up/down latency of a web app.

  - by Brodie

  I am trying to work out how to calculate the latency of requests through a web-app (Javascript) to a .net webservice. Currently I am essentially trying to sync both client and server time, which when hitting the webservice I can look at the offset (which would accurately show the 'up' latency. The problem is - when you sync the time's, you have to factor in latency for that also. So currently I am timeing the sync request (round trip) and dividing by 2, in an attempt to get the 'up' latency...and then modify the sync accordingly. This works on the assumption that latency is symmetrical, which it isn't. Does anyone know a procedure that would be able to determine specifically the up/down latency of a JS http request to a .net service? If it needs to involve multiple handshakes thats fine, what ever is as accurate as possible. Thanks!!

• .pl or .cgi for perl web script file,which one is more popular?

  - by Nano HE

  HI. I created two files 'hello.pl' and 'hello.cgi' with the code below. #!/usr/bin/perl print "Content-type:text/html\n\n"; print "hello world"; I can view the page via both http://www.mydomain.com/cgi-bin/hello.pl and http://www.mydomain.com/cgi-bin/hello.cgi. Which one is more sense in Perl web dev? BTW, the directory of 'cgi-bin' created by my VPS server, Do I need contact with my VPS support to remove it or just remain it like this URL style? Maybe http://www.mydomain.com/perDev/hello.cgi is better?

• How does my ASP.NET app get the SMTP settings automatically from web.config?

  - by Ryan

  I noticed that we always just are like: SmtpClient mSmtpClient = new SmtpClient(); // Send the mail message mSmtpClient.Send(mMailMessage); And the only place the credentials are set are in web.config: <system.net> <mailSettings> <smtp> <network host="xxx.xx.xxx.229" userName="xxxxxxxx" password="xxxxxxxx"/> </smtp> </mailSettings> </system.net> So my question is, how does it automagically get them out?

• How can I access the copy buffer on the web?

  - by Ólafur Waage

  Wild question here. Is it possible to access the copy buffer on the web. What I mean is. Can I go into Photoshop. Select a piece of a photo. Copy that piece and paste it into some element. That something would be like a Java applet or Flash or Silverlight or anything. I am just wondering if it is possible and if someone could point me in a direction. Since a few google searches have only found where you can copy files and paste via a Java applet.

• Microsoft Excel; Two conditions have to be true then be counted

  - by Chris Jones

  I'm working on a spreadsheet that two conditions have to true in order to be counted. If the month is January, and the number next to it is less than or equal to 30, then it's counted. Same rule applies for all the other months. Thus far, I have: =COUNTIFS(Sheet1!D2:D7,(SUMPRODUCT(--(MONTH(D2:D7)=1))),Sheet1!E2:E7,(COUNTIFS(E2:E7,"<=30"))) For example: Column D Jan 1, 2014 Feb 3, 2014 Feb 16, 2014 Mar 5, 2014 Mar 13, 2014 Mar 29, 2014 Column E 37 25 30 31 1 16 Outcome Jan 0 Feb 2 Mar 2

• Will using a VCS help me as a web dev?

  - by jsims281

  I'm thinking of trying a VCS such as subversion, to manage my next project, but I'm not sure if will offer any real benefits for me as a web developer. As I understand it, one of the major benefits of a VCS is that a group of people can work on a project at once. Reading material on the subject seems pretty one sided: "Using a version control system is an absolute must for a developer of a project above a few hundred lines of code" ...and I've got a feeling it could become a chore, with not many benefits. I work on development server on the local network, so any amount of people can work on the files already. If anyone needs to get in remotely, they use FTP. What would a modern version control system give me on top of this?

• Do you use a grid system when designing a web page?

  - by johnny

  I'm trying to figure out why I would use a grid system. I have read some but I just don't get it. I'm used to just putting stuff in html on a page and beind done with it but I have a new project and would like to use a grid because apparently it is a best practice. I read in one article referenced in another SO question and it said that grid design was in all sorts of development, even application form design. That made me think of things like snap to grid, etc. and I didn't know if the grid in the web design sphere was the same. I was hoping someone could give me a brief but not overly complicated view and not a link to Google which I have used already. Thank you for any help.

• coldfusion class path for multiple services - only recognizing first directory

  - by ffc

  Hi, I am trying to use multiple web services on a single CF page. I have entered the stubs directory for each of the web services in the ColdFusion Class Path within administrator server settings java and jvm paths are listed separated by commas: c:\coldfusion9\stubs\ws1,c:\coldfusion9\stubs\ws2 for some reason, only the web service whose stub path is listed first will work. When I try to call the second web service, I get a "web service operation ... cannot be found" but if i switch the order of paths listed in the admin settings and restart the service, the web service listed first now will work. any ideas on how to manage multiple web services and their stubs ? thanks!

• ASP.NET web services leak memory when (de)serializing disposable objects?

  - by Serilla

  In the following two cases, if Customer is disposable (implementing IDisposable), I believe it will not be disposed by ASP.NET, potentially being the cause of a memory leak: [WebMethod] public Customer FetchCustomer(int id) { return new Customer(id); } [WebMethod] public void SaveCustomer(Customer value) { // save it } This flaw applies to any IDisposable object. So returning a DataSet from a ASP.NET web service, for example, will also result in a memory leak - the DataSet will not be disposed. In my case, Customer opened a database connection which was cleaned up in Dispose - except Dispose was never called resulting in loads of unclosed database connections. I realise there a whole bunch of bad practices being followed here (its only an example anyway), but the point is that ASP.NET - the (de)serializer - is responsible for disposing these objects, so why doesn't it? This is an issue I was aware of for a while, but never got to the bottom of. I'm hoping somebody can confirm what I have found, and perhaps explain if there is a way of dealing with it.
