  • Handling asynchronous responses

    - by James P.
    I'm building an FTP client from scratch and I've noticed that the response codes aren't immediate (which is no surprise). What would be a good approach for getting the corresponding code to a command? Below is an example of the output of Filezilla server. The response code is the three digits near the end of each line.

  • jasper Chart can't be displayed using tomcat

    - by Aru
    Hi, I am using jasperreports-3.5.0 to generate timeSeries chart. When I run it through eclipse it is working fine. But if I create .war file of project and run through tomcat by deploying the project into tomcat / webapps folder then chart can not be displayed. What could be the problem? code: PrintWriter out = response.getWriter(); response.setContentType("text/html"); JRDataSource dataSource = createReportDataSource(perfArrayListSample.toArray()); InputStream input = getServletConfig().getServletContext().getResourceAsStream("/CpuUsage.jrxml"); JasperDesign design = JRXmlLoader.load(input); JasperReport report = JasperCompileManager.compileReport(design); JasperPrint print = JasperFillManager.fillReport(report, new HashMap(), dataSource); JRHtmlExporter exporter = new JRHtmlExporter(); request.getSession().setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, print); exporter.setParameter(JRExporterParameter.JASPER_PRINT, print); exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out); exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "image?ver="+new Date().getTime() +"&image="); exporter.exportReport(); perfArrayListSample.clear();

  • Trouble parsing quotes with SAX parser (javax.xml.parsers.SAXParser)

    - by johnrock
    When using a SAX parser, parsing fails when there is a " in the node content. How can I resolve this? Do I need to convert all " characters? In other words, anytime I have a quote in a node: <node>characters in node containing "quotes"</node> That node gets butchered into multiple character arrays when the Handler is parsing it. Is this normal behaviour? Why should quotes cause such a problem? Here is the code I am using: import javax.xml.parsers.SAXParser; import javax.xml.parsers.SAXParserFactory; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.client.methods.HttpGet; import org.xml.sax.InputSource; import org.xml.sax.XMLReader; ... HttpGet httpget = new HttpGet(GATEWAY_URL + "/"+ question.getId()); httpget.setHeader("User-Agent", PayloadService.userAgent); httpget.setHeader("Content-Type", "application/xml"); HttpResponse response = PayloadService.getHttpclient().execute(httpget); HttpEntity entity = response.getEntity(); if(entity != null) { SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); XMLReader xr = sp.getXMLReader(); ConvoHandler convoHandler = new ConvoHandler(); xr.setContentHandler(convoHandler); xr.parse(new InputSource(entity.getContent())); entity.consumeContent(); messageList = convoHandler.getMessageList(); }

  • Asynchronous crawling F#

    - by jlezard
    When crawling on webpages I need to be careful as to not make too many requests to the same domain, for example I want to put 1 s between requests. From what I understand it is the time between requests that is important. So to speed things up I want to use async workflows in F#, the idea being make your requests with 1 sec interval but avoid blocking things while waiting for request response. let getHtmlPrimitiveAsyncTimer (uri : System.Uri) (timer:int) = async{ let req = (WebRequest.Create(uri)) :?> HttpWebRequest req.UserAgent<-"Mozilla" try Thread.Sleep(timer) let! resp = (req.AsyncGetResponse()) Console.WriteLine(uri.AbsoluteUri+" got response") use stream = resp.GetResponseStream() use reader = new StreamReader(stream) let html = reader.ReadToEnd() return html with | _ as ex -> return "Bad Link" } Then I do something like: let uri1 = System.Uri "http://rue89.com" let timer = 1000 let jobs = [|for i in 1..10 -> getHtmlPrimitiveAsyncTimer uri1 timer|] jobs |> Array.mapi(fun i job -> Console.WriteLine("Starting job "+string i) Async.StartAsTask(job).Result) Is this alright ? I am very unsure about 2 things: -Does the Thread.Sleep thing work for delaying the request ? -Is using StartTask a problem ? I am a beginner (as you may have noticed) in F# (coding in general actually ), and everything envolving Threads scares me :) Thanks !!

  • EPIPE blocks server

    - by timn
    I have written a single-threaded asynchronous server in C running on Linux: The socket is non-blocking and as for polling, I am using epoll. Benchmarks show that the server performs fine and according to Valgrind, there are no memory leaks or other problems. The only problem is that when a write() command is interrupted (because the client closed the connection), the server will encounter a SIGPIPE. I am doing the interrupted artifically by running the benchmarking utility "siege" with the parameter -b. It does lots of requests in a row which all work perfectly. Now I press CTRL-C and restart the "siege". Sometimes I am lucky and the server does not manage to send the full response because the client's fd is invalid. As expected errno is set to EPIPE. I handle this situation, execute close() on the fd and then free the memory related to the connection. Now the problem is that the server blocks and does not answer properly anymore. Here is the strace output: accept(3, {sa_family=AF_INET, sin_port=htons(50611), sin_addr=inet_addr("127.0.0.1")}, [16]) = 5 fcntl64(5, F_GETFD) = 0 fcntl64(5, F_SETFL, O_RDONLY|O_NONBLOCK) = 0 epoll_ctl(4, EPOLL_CTL_ADD, 5, {EPOLLIN|EPOLLERR|EPOLLHUP|EPOLLET, {u32=158310248, u64=158310248}}) = 0 epoll_wait(4, {{EPOLLIN, {u32=158310248, u64=158310248}}}, 128, -1) = 1 read(5, "GET /user/register HTTP/1.1\r\nHos"..., 4096) = 161 write(5, "HTTP/1.1 200 OK\r\nContent-Type: t"..., 106) = 106 <<<<< write(5, "00001000\r\n", 10) = -1 EPIPE (Broken pipe) <<<<< Why did the previous write() work fine but not this one? --- SIGPIPE (Broken pipe) @ 0 (0) --- As you can see, the client establishes a new connection which consequently is accepted. Then, it's added to the EPOLL queue. epoll_wait() signalises that the client sent data (EPOLLIN). The request is parsed and and a response is composed. Sending the headers works fine but when it comes to the body, write() results in an EPIPE. It is not a bug in "siege" because it blocks any incoming connections, no matter from which client.

  • How do I use Perl's WWW::Facebook::API to publish to a user's newsfeed?

    - by Russell C.
    We use Facebook Connect on our site in conjunction with the WWW::Facebook::API CPAN module to publish to our users newsfeed when requested by the user. So far we've been able to successfully update the user's status using the following code: use WWW::Facebook::API; my $facebook = WWW::Facebook::API->new( desktop => 0, api_key => $fb_api_key, secret => $fb_secret, session_key => $query->cookie($fb_api_key.'_session_key'), session_expires => $query->cookie($fb_api_key.'_expires'), session_uid => $query->cookie($fb_api_key.'_user') ); my $response = $facebook->stream->publish( message => qq|Test status message|, ); However, when we try to update the code above so we can publish newsfeed stories that include attachments and action links as specified in the Facebook API documentation for Stream.Publish, we have tried about 100 different ways without any success. According to the CPAN documentation all we should have to do is update our code to something like the following and pass the attachments & action links appropriately which doesn't seem to work: my $response = $facebook->stream->publish( message => qq|Test status message|, attachment => $json, action_links => [@links], ); For example, we are passing the above arguments as follows: $json = qq|{ 'name': 'i\'m bursting with joy', 'href': ' http://bit.ly/187gO1', 'caption': '{*actor*} rated the lolcat 5 stars', 'description': 'a funny looking cat', 'properties': { 'category': { 'text': 'humor', 'href': 'http://bit.ly/KYbaN'}, 'ratings': '5 stars' }, 'media': [{ 'type': 'image', 'src': 'http://icanhascheezburger.files.wordpress.com/2009/03/funny-pictures-your-cat-is-bursting-with-joy1.jpg', 'href': 'http://bit.ly/187gO1'}] }|; @links = ["{'text':'Link 1', 'href':'http://www.link1.com'}","{'text':'Link 2', 'href':'http://www.link2.com'}"]; The above, nor any of the other representations we tried seem to work. I'm hoping some other perl developer out there has this working and can explain how to create the attachment and action_links variables appropriately in Perl for posting to the Facebook news feed through WWW::Facebook::API. Thanks in advance for your help!

  • A simple WCF Service (POX) without complex serialization

    - by jammer59
    I'm a complete WCF novice. I'm trying to build a deploy a very, very simple IIS 7.0 hosted web service. For reasons outside of my control it must be WCF and not ASMX. It's a wrapper service for a pre-existing web application that simply does the following: 1) Receives a POST request with the request body XML-encapsulated form elements. Something like valuevalue. This is untyped XML and the XML is atomic (a form) and not a list of records/objects. 2) Add a couple of tags to the request XML and the invoke another HTTP-based service with a simple POST + bare XML -- this will actually be added by some internal SQL ops but that isn't the issue. 3) Receive the XML response from the 3rd party service and relay it as the response to the original calling client in Step 1. The clients (step 1) will be some sort of web-based scripting but could be anything .aspx, python, php, etc. I can't have SOAP and the usual WCF-based REST examples with their contracts and serialization have me confused. This seems like a very common and very simple problem conceptually. It would be easy to implement in code but IIS-hosted WCF is a requirement. Any pointers?

  • How test that ASP.NET MVC route redirects to other site?

    - by Matt Lacey
    Due to a prinitng error in some promotional material I have a site that is receiving a lot of requests which should be for one site arriving at another. i.e. The valid sites are http://site1.com/abc & http://site2.com/def but people are being told to go to http://site1.com/def. I have control over site1 but not site2. site1 contains logic for checking that the first part of the route is valid in an actionfilter, like this: public override void OnActionExecuting(ActionExecutingContext filterContext) { base.OnActionExecuting(filterContext); if ((!filterContext.ActionParameters.ContainsKey("id")) || (!manager.WhiteLabelExists(filterContext.ActionParameters["id"].ToString()))) { if (filterContext.ActionParameters["id"].ToString().ToLowerInvariant().Equals("def")) { filterContext.HttpContext.Response.Redirect("http://site2.com/def", true); } filterContext.Result = new ViewResult { ViewName = "NoWhiteLabel" }; filterContext.HttpContext.Response.Clear(); } } I'm not sure how to test the redirection to the other site though. I already have tests for redirecting to "NoWhiteLabel" using the MvcContrib Test Helpers, but these aren't able to handle (as far as I can see) this situation. How do I test the redirection to antoher site?

  • accessing parsed JSON on the iPhone SDK

    - by itai alter
    Hello All! I've been following the great tutorial about (iPhone, json and Flickr API and I did manage to access the parsed json info just fine. Now I'm trying to do the same thing with the Twitter API, and I am able to get the json info and parse it, but I can't seem to access it like in Flickr. I noticed that the json info that is retrieved from Twitter is a little different from Flickr. The Flickr json info starts straight with a curly braces ({), while the Twitter json info starts with a square bracket and then a curly braces ([{). I understand that it means it's an array inside the json info, but I don't know how to access it. In the Flickr example, I access the objects like so (the second line takes the number of pages Flickr has reported): NSDictionary *results = [jsonString JSONValue]; pagesString = [[results objectForKey:@"photos"] objectForKey:@"pages"]; but I can't seem to access the Twitter response in the same way... Does anyone know of a solution? (here's an example of the Twitter JSON response: api.twitter.com/1/statuses/public_timeline.json ) Thanks a bunch!

  • Looping through a SimpleXML object, or turning the whole thing into an array.

    - by Coffee Cup
    I'm trying to work out how to iterate though a returned SimpleXML object. I'm using a toolkit called Tarzan AWS, which connects to Amazon Web Services (SimpleDB, S3, EC2, etc). I'm specifically using SimpleDB. I can put data into the Amazon SimpleDB service, and I can get it back. I just don't know how to handle the SimpleXML object that is returned. The Tarzan AWS documentation says this: Look at the response to navigate through the headers and body of the response. Note that this is an object, not an array, and that the body is a SimpleXML object. Here's a sample of the returned SimpleXML object: [body] = SimpleXMLElement Object ( [QueryWithAttributesResult] = SimpleXMLElement Object ( [Item] = Array ( [0] = SimpleXMLElement Object ( [Name] = message12413344443260 [Attribute] = Array ( [0] = SimpleXMLElement Object ( [Name] = active [Value] = 1 ) [1] = SimpleXMLElement Object ( [Name] = user [Value] = john ) [2] = SimpleXMLElement Object ( [Name] = message [Value] = This is a message. ) [3] = SimpleXMLElement Object ( [Name] = time [Value] = 1241334444 ) [4] = SimpleXMLElement Object ( [Name] = id [Value] = 12413344443260 ) [5] = SimpleXMLElement Object ( [Name] = ip [Value] = 10.10.10.1 ) ) ) [1] = SimpleXMLElement Object ( [Name] = message12413346907303 [Attribute] = Array ( [0] = SimpleXMLElement Object ( [Name] = active [Value] = 1 ) [1] = SimpleXMLElement Object ( [Name] = user [Value] = fred ) [2] = SimpleXMLElement Object ( [Name] = message [Value] = This is another message ) [3] = SimpleXMLElement Object ( [Name] = time [Value] = 1241334690 ) [4] = SimpleXMLElement Object ( [Name] = id [Value] = 12413346907303 ) [5] = SimpleXMLElement Object ( [Name] = ip [Value] = 10.10.10.2 ) ) ) ) So what code do I need to get through each of the object items? I'd like to loop through each of them and handle it like a returned mySQL query. For example, I can query SimpleDB and then loop though the SimpleXML so I can display the results on the page. Alternatively, how do you turn the whole shebang into an array? I'm new to SimpleXML, so I apologise if my questions aren't specific enough.

  • How Does MVC Handle Missing Data Requirements

    - by Don Bakke
    I'm teaching myself MVC concepts in hopes of applying them to a non-OO/procedural development environment. I am pretty sure I understand simple View - Request - Controller - Request - Model - Response - Controller - Response - View flow. What I am struggling with is understanding more complex scenarios. For instance, let's say I have a shopping cart form with a button for 'Calculate Shipping'. Normally a click on this button will follow the above flow. But what if there is missing data, like the zip code? Should the View verify this first and alert the user before making a 'Calculate Shipping' request? Or should the request be made and the Model returns a notification that critical data is missing? If the latter, does the Controller instruct the View to alert the user? What if I wanted to prompt the user for the missing zip code (perhaps in a popup input display) and then automatically request the 'Calculate Shipping' method again? I suppose this gets into the question of how smart a View ought to be. It seems that MVC has evolved due to richer UI and automation (such as with data-binding) and this muddies the water from a purist MVC perspective. Any thoughts are greatly appreciated.

  • WCF and streaming requests and responses

    - by Cheeso
    Is it correct that in WCF, I cannot have a service write to a stream that is received by the client? My understanding is that streaming is supported in WCF for requests, responses, or both. Is it true that in all cases, the receiver of the stream must invoke Read ? I would like to support a scenario where the receiver of the stream can Write on it. Is this supported? Let me show it this way. The simplest example of Streaming in WCF is the service returning a FileStream to a client. This is a streamed response. The server code is like this: [ServiceContract] public interface IStreamService { [OperationContract] Stream GetData(string fileName); } public class StreamService : IStreamService { public Stream GetData(string filename) { FileStream fs = new FileStream(filename, FileMode.Open) return fs; } } And the client code is like this: StreamDemo.StreamServiceClient client = new WcfStreamDemoClient.StreamDemo.StreamServiceClient(); Stream str = client.GetData(@"c:\path\to\myfile.dat"); do { b = str.ReadByte(); //read next byte from stream ... } while (b != -1); (example taken from http://blog.joachim.at/?p=33) Clear, right? The server returns the Stream to the client, and the client invokes Read on it. Is it possible for the client to provide a Stream, and the server to invoke Write on it? In other words, rather than a pull model - where the client pulls data from the server - it is a push model, where the client provides the "sink" stream and the server writes into it. Is this possible in WCF, and if so, how? What are the config settings required for the binding, interface, etc? The analogy is the Response.OutputStream from an ASP.NET request. In ASPNET, any page can invoke Write on the output stream, and the content is received by the client. Can I do something similar in WCF? Thanks.

  • Authorize.net Parameters with activemerchant

    - by rpflo
    I'm using authorize.net and activemerchant in a rails app. When I make a purchase authorize.net sends back an email with information about the purchase. I should be able to send them the billing and shipping address information and have that returned in the email, but it's not returning any of the information, obviously I've got the varable names wrong, anybody know what they should be? I've been pouring over the authorize.net api docs and activemerchant's but can't find what I need. My purchase method on an orders model looks like this: def purchase purchase_options = { :ip => ip_address, :first_name => first_name, :last_name => last_name, :address => billing_street_address, :city => billing_city, :state => billing_state, :country => "US", :zip => billing_zip, :ship_to_first_name => first_name, :ship_to_last_name => last_name, :ship_to_address => shipping_street_address, :ship_to_city => shipping_city, :ship_to_state => shipping_state, :ship_to_country => "US", :ship_to_zip => shipping_zip } response = GATEWAY.purchase(price_in_cents, credit_card, purchase_options) # other transaction stuff response.success? end

  • Using ThreadPool.QueueUserWorkItem - thread unexpectedly exits

    - by alex
    I have the following method: public void PutFile(string ID, Stream content) { try { ThreadPool.QueueUserWorkItem(o => putFileWorker(ID, content)); } catch (Exception ex) { OnPutFileError(this, new ExceptionEventArgs { Exception = ex }); } } The putFileWorker method looks like this: private void putFileWorker(string ID, Stream content) { //Get bucket name: var bucketName = getBucketName(ID) .ToLower(); //get file key var fileKey = getFileKey(ID); try { //if the bucket doesn't exist, create it if (!Amazon.S3.Util.AmazonS3Util.DoesS3BucketExist(bucketName, s3client)) s3client.PutBucket(new PutBucketRequest { BucketName = bucketName, BucketRegion = S3Region.EU }); PutObjectRequest request = new PutObjectRequest(); request.WithBucketName(bucketName) .WithKey(fileKey) .WithInputStream(content); S3Response response = s3client.PutObject(request); var xx = response.Headers; OnPutFileCompleted(this, new ValueEventArgs { Value = ID }); } catch (Exception e) { OnPutFileError(this, new ExceptionEventArgs { Exception = e }); } } I've created a little console app to test this. I wire up event handlers for the OnPutFileError and OnPutFileCompleted events. If I call my PutFile method, and step into this, it gets to the "//if the bucket doesn't exist, create it" line, then exits. No exception, no errors, nothing. It doesn't complete (i've set breakpoints on my event handlers too) - it just exits. If I run the same method without the ThreadPool.QueueUserWorkItem then it runs fine... Am I missing something?

  • How to build Graceful Degradation AJAX web page?

    - by Morgan Cheng
    I want to build web page with "Graceful Degradation". That is, the web page functions even javascript is disabled. Now I have to make design decision on the format of AJAX response. If javascript is disabled, each HTTP request to server will generate HTML as response. The browser refreshes with the returned HTML. That's fine. If javascript is enabled, each AJAX HTTP request to server will generate ... well, JSON or HTML. If it is HTML, it is easy to implement. Just have javascript to replace part of page with the returned HTML. And, in server side, not much code change is needed. If it is JSON, then I have to implement JSON-to-html logic in javascript again which is almost duplicate of server side logic. Duplication is evil. I really don't like it. The benefit is that the bandwidth usage is better than HTML, which brings better performance. So, what's the best solution to Graceful Degradation? AJAX request better to return JSON or HTML?

  • 406 Not Acceptable error when using Jquery $.post in Firefox but not in Safari or Chrome

    - by jlfenaux
    I'm using Jquery (1.3.2) $.post command to trigger an ajax call to a rails server. The code works great on Safari and on Google Chrome (mac), but when I tried it on Firefox (3.5.7), I got a weird '406 Not Acceptable' error. When I look at the headers, it Firefox indicated that it accepted only ' text/javascript' responses. And the response Content-Type was 'text/html; charset=utf-8'. In Chrome the accepted types were 'application/json, text/javascript, /, text/javascript' and the response Content-Type was 'application/json; charset=utf-8'. I tried to force the content type in rails to 'text/javascript' format.json do render :json => @races.to_json, :content_type => 'text/javascript' end The content type is indeed changed in Chrome, but not in Firefox where it remains 'text/html'. Here is the code I used to trigger the ajax call. $.post( "/locator", params, function(data){...}, "json" ); Is there something I can do to make this work in Firefox? Thanks

  • Trouble Shoot JavaScript Function in IE

    - by CreativeNotice
    So this function works fine in geko and webkit browsers, but not IE7. I've busted my brain trying to spot the issue. Anything stick out for you? Basic premise is you pass in a data object (in this case a response from jQuery's $.getJSON) we check for a response code, set the notification's class, append a layer and show it to the user. Then reverse the process after a time limit. function userNotice(data){ // change class based on error code returned var myClass = ''; if(data.code == 200){ myClass='success'; } else if(data.code == 400){ myClass='error'; } else{ myClass='notice'; } // create message html, add to DOM, FadeIn var myNotice = '<div id="notice" class="ajaxMsg '+myClass+'">'+data.msg+'</div>'; $("body").append(myNotice); $("#notice").fadeIn('fast'); // fadeout and remove from DOM after delay var t = setTimeout(function(){ $("#notice").fadeOut('slow',function(){ $(this).remove(); }); },5000); }

Response: Content-Disposition:attachment; filename*=UTF-8''%D0%A1%D1%83%D0%BC%D0%BC%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5_2012.10.18-13.36.06.xls Content-Length:203776 Content-Type:application/vnd.ms-excel Date:Thu, 18 Oct 2012 09:36:06 GMT Server:ASP.NET Development Server/10.0.0.0 X-AspNet-Version:4.0.30319 X-AspNetMvc-Version:3.0 And from production server I download a file with the name of the controller's action + correct extension "Uploadfile.xls", which is wrong. Response: Content-Disposition:attachment; filename="=?utf-8?B?0KHRg9C80LzQuNGA0L7QstCw0L3QuNC1XzIwMTIuMTAuMTgtMTMuMzYu?=%0d%0a =?utf-8?B?NTUueGxz?=" Content-Length:203776 Content-Type:application/vnd.ms-excel Date:Thu, 18 Oct 2012 09:36:55 GMT Server:Microsoft-IIS/7.5 X-AspNet-Version:4.0.30319 X-AspNetMvc-Version:3.0 X-Powered-By:ASP.NET Web.config files are the same on both machines. Why does filename gets encoded differently for the same browser? Are there any kinds of default settings in web.config that are different on machines that I am missing?

  • ActiveScaffold custom action_link that should respond like update

    - by doug316
    I have a custom action link which is :inline and :post. It's a quick-link to update an attribute, and that part works just fine. After the action, my intent is to respond just like it was an update, so the row is re-rendered in the index. After the record is updated in my controller action, I call respond_to_action(:create) Just like in the create method in active scaffold. It seems like the content of the javascript response is returned correctly to the client, however, the problem: The content-type of the response header is "text/html" instead of "text/javascript", unlike with an actual update. So the JS is not executed and the row doesn't update. I can't figure out what the difference could possibly be here, I've traced extensively and even have replaced the respond_to_action with: respond_to do |format| format.js do render ... end end And it still won't set the content-type like every other action in the app. Anybody have a clue here? Something in active scaffold must be overriding the content-type and I can't figure out what it might be. Surprising this isn't documented, this doesn't seem like an unusual use-case, making an action a slave to the update re-render.

  • Calling a .net webservice from a plain HTML site using jQuery

    - by pwee167
    Hi guys, I wanted to know it is possible to call a hosted .net web service from a HTML page using jQuery? I tried this piece of code, but it doesn't work for me: $('#myForm').click(function() { $.ajax({ type: "POST", data: '{}', url: "http://localhost:49590/Service.asmx?op=HelloWorld", contentType: "application/json; charset=utf-8", dataType: "json", success: function(response) { alert(response.d); }, failure: function(result) { alert(result.status + ' ' + result.statusText); } }); }); And the webservice is as such: [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService] public class Service : System.Web.Services.WebService { [WebMethod] public string HelloWorld() { return "Hello World"; } } I have searched for this and found only examples where it is done from asp.net or asp.net mvc projects. I am not sure what I am missing but I thought this was possible from a plain HTML site with javascript, so can someone please point me in the right direction. Cheers!

  • Java resource closing

    - by Bob
    Hi, I'm writing an app that connect to a website and read one line from it. I do it like this: try{ URLConnection connection = new URL("www.example.com").openConnection(); BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream())); String response = rd.readLine(); rd.close(); }catch (Exception e) { //exception handling } Is it good? I mean, I close the BufferedReader in the last line, but I do not close the InputStreamReader. Should I create a standalone InputStreamReader from the connection.getInputStream, and a BufferedReader from the standalone InputStreamReader, than close all the two readers? I think it will be better to place the closing methods in the finally block like this: InputStreamReader isr = null; BufferedReader br = null; try{ URLConnection connection = new URL("www.example.com").openConnection(); isr = new InputStreamReader(connection.getInputStream()); br = new BufferedReader(isr); String response = br.readLine(); }catch (Exception e) { //exception handling }finally{ br.close(); isr.close(); } But it is ugly, because the closing methods can throw exception, so I have to handle or throw it. Which solution is better? Or what would be the best solution?
