• PHP problem with getimagesize()

  - by RobHardgood

  I'm using the getimagesize() function in PHP and it keeps returning an error: getimagesize(image.php?name=username&pic=picture) [function.getimagesize]: failed to open stream: No such file or directory I'm not doing anything strange with it. The only problem I can imagine is that the path URL is another PHP script that returns a page with an image header, and there is an ampersand in that URL. Here is my code: $location = "image.php?name=username&pic=picture"; $size = getimagesize($location);

• Two collections and a for loop. (Urgent help needed) Checking an object variable against an inputted

  - by Elliott

  Hi there, I'm relatively new to java, I'm certain the error is trivial. But can't for the life of me spot it. I have an end of term exam on monday and currently trying to get to grips with past papers! Anyway heregoes, in another method (ALGO_1) I search over elements of and check the value H_NAME equals a value entered in the main. When I attempt to run the code I get a null pointer exception, also upon trying to print (with System.out.println etc) the H_NAME value after each for loop in the snippet I also get a null statement returned to me. I am fairly certain that the collection is simply not storing the data gathered up by the Scanner. But then again when I check the collection size with size() it is about the right size. Either way I'm pretty lost and would appreciate the help. Main questions I guess to ask are: from the readBackground method is the data.add in the wrong place? is the snippet simply structured wrongly? oh and another point when I use System.out.println to check the Background object values name, starttime, increment etc they print out fine. Thanks in advance.(PS im guessing the formatting is terrible, apologies.) snippet of code: for(Hydro hd: hydros){ System.out.println(hd.H_NAME); for(Background back : backgs){ System.out.println(back.H_NAME); if(back.H_NAME.equals(hydroName)){ //get error here public static Collection<Background> readBackground(String url) throws IOException { URL u = new URL(url); InputStream is = u.openStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader b = new BufferedReader(isr); String line =""; Vector<Background> data = new Vector<Background>(); while((line = b.readLine())!= null){ Scanner s = new Scanner(line); String name = s.next(); double starttime = Double.parseDouble(s.next()); double increment = Double.parseDouble(s.next()); double sum = 0; double p = 0; double nterms = 0; while((s.hasNextDouble())){ p = Double.parseDouble(s.next()); nterms++; sum += p; } double pbmean = sum/nterms; Background SAMP = new Background(name, starttime, increment, pbmean); data.add(SAMP); } return data; } Edit/Delete Message

• Trying to run multiple HTTP requests in parallel, but being limited by Windows (registry)

  - by Nailuj

  I'm developing an application (winforms C# .NET 4.0) where I access a lookup functionality from a 3rd party through a simple HTTP request. I call an url with a parameter, and in return I get a small string with the result of the lookup. Simple enough. The challenge is however, that I have to do lots of these lookups (a couple of thousands), and I would like to limit the time needed. Therefore I would like to run requests in parallel (say 10-20). I use a ThreadPool to do this, and the short version of my code looks like this: public void startAsyncLookup(Action<LookupResult> returnLookupResult) { this.returnLookupResult = returnLookupResult; foreach (string number in numbersToLookup) { ThreadPool.QueueUserWorkItem(lookupNumber, number); } } public void lookupNumber(Object threadContext) { string numberToLookup = (string)threadContext; string url = @"http://some.url.com/?number=" + numberToLookup; WebClient webClient = new WebClient(); Stream responseData = webClient.OpenRead(url); LookupResult lookupResult = parseLookupResult(responseData); returnLookupResult(lookupResult); } I fill up numbersToLookup (a List<String>) from another place, call startAsyncLookup and provide it with a call-back function returnLookupResult to return each result. This works, but I found that I'm not getting the throughput I want. Initially I thought it might be the 3rd party having a poor system on their end, but I excluded this by trying to run the same code from two different machines at the same time. Each of the two took as long as one did alone, so I could rule out that one. A colleague then tipped me that this might be a limitation in Windows. I googled a bit, and found amongst others this post saying that by default Windows limits the number of simultaneous request to the same web server to 4 for HTTP 1.0 and to 2 for HTTP 1.1 (for HTTP 1.1 this is actually according to the specification (RFC2068)). The same post referred to above also provided a way to increase these limits. By adding two registry values to [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings] (MaxConnectionsPerServer and MaxConnectionsPer1_0Server), I could control this myself. So, I tried this (sat both to 20), restarted my computer, and tried to run my program again. Sadly though, it didn't seem to help any. I also kept an eye on the Resource Monitor (see screen shot) while running my batch lookup, and I noticed that my application (the one with the title blacked out) still only was using two TCP connections. So, the question is, why isn't this working? Is the post I linked to using the wrong registry values? Is this perhaps not possible to "hack" in Windows any longer (I'm on Windows 7)? Any ideas would be highly appreciated :) And just in case anyone should wonder, I have also tried with different settings for MaxThreads on ThreadPool (everyting from 10 to 100), and this didn't seem to affect my throughput at all, so the problem shouldn't be there either.

  hi, I am developing a multi-language site in django. In order to improve SEO, i will give every language version a unique URL like below, english: www.foo.com/en/index.html french: www.foo.com/fr/index.html chinese: www.foo.com/zh/index.html However, Django looks for a "django_language" key in user's session or cookie to determine language in default, so,Despite which language user chose, URL is always the same. for instance: http://www.foo.com/index.html how to resolve this problem ? thank you!

• Querystring formatting in asp.net MVC 2

  - by Stuart

  Seems like a straitforward question but I can't quite figure it out myself... I have an actionlink like so Html.ActionLink( "Test", "test", new { q = "search+twitter" } ) This produces a url string as follows http://myserver/test?q=search%2Btwitter But i would like to preserve the plus sign (which i assume is being UrlPathEncoded) so that I get the following url http://myserver/test?q=search+twitter Is there an easy way to do this whilst still using Html.ActionLink ?

• JQuery.ajax(): Problem with parameter data when consuming a WCF Service

  - by Torben H.

  Hello, I'm using JQuery to consume a WCF Service. Actually this works fine: var para = ' { "Parameter" : { "ID" : "5", "Name" : "Peter" } }' $.ajax({ type: "POST", contentType: "application/json", data: para, url: url success: success }); But I don't want to pass the data parameter as String and I think it should be possible to pass ist as array in any way. Like that: var para = { "Parameter" : { "ID" : 5, "Name" : "Peter" } } But when I try this I'm getting an error. What I'm doing wrong? Thanks

• How to use jaxb_commons plugins from maven

The problem is that I can't seem to figure out how to do so from maven, the repository isn't clear from the documentation and the only example (bellow) doesn't work, it seems to ignore the plugin (maven reports no error about not finding it) or the plugin doesn't have all the adds-ons currently listed in the project documentation: <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <version>0.6.1</version> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <generatePackage>br.com.wonder.nfe.xml</generatePackage> <args> <arg>-Xifins</arg> </args> <plugins> <plugin> <groupId>org.jvnet.jaxb2_commons</groupId> <artifactId>basic</artifactId> <version>0.4.1.5</version> </plugin> </plugins> </configuration> </plugin> I have these in the root pom: <pluginRepositories> <pluginRepository> <id>maven2-repository.dev.java.net</id> <url>http://download.java.net/maven/2</url> </pluginRepository> <pluginRepository> <id>maven-repository.dev.java.net</id> <name>Java.net Maven 1 Repository (legacy)</name> <url>http://download.java.net/maven/1</url> <layout>legacy</layout> </pluginRepository> </pluginRepositories> Running that gives: Error while setting CmdLine options '[-Xifins, -episode, /home/administrador/JavaApp/wnfe3/wnfe-ejb/target/generated-sources/xjc/META-INF/sun-jaxb.episode]'!
