  • Execute Ant task with Maven

    - by Gonzalo
    Hi, I'm trying to execute with Maven some test written using Ant tasks. I generated the files required to import the task into Maven, but I can't execute them. My POM is defined this way: <build> <plugins> <plugin> <artifactId>maven-ant-plugin</artifactId> <version>2.1</version> <executions> <execution> <phase>generate-sources</phase> <configuration> <tasks> <echo message="Hello, maven"/> </tasks> </configuration> <goals> <goal>run</goal> </goals> </execution> </executions> </plugin> </plugins> </build> I try to execute that message, but I get an error with run: [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] 'run' was specified in an execution, but not found in the plugin But, if I run: "mvn antrun:run", I know that this can not run the task. An if I've different targets, how do I call them from Maven? I've the pom.xml, and build.xml with the ant tasks. Thanks. Gonzalo

  • Data Collection (Offline - no internet) and then syncing it to generate reports from server

    - by Nishant
    So, I have a new project I am planning on taking, and needed to know what skills will be required to achieve this project. The project is to do intensive data collection in the field where they don't have internet access. As part of the data collection, images will be uploaded as part of the data collection which will have to be resized, etc. Once the data collection occurs, this data needs to be consolidated and reported on. I am thinking there are two ways of generating the report. 1. Into a PDF that can be designed. 2. Is there a way to generate an executable file (since the PDF will be huge due to multiple images, etc) and the executable file is navigation friendly with drop-downs etc. It might not be an executable file, but could be a web page or some way that this can be delivered to the client in a friendly professional way. The PDF will have to be generated somehow so that it can be printed as a hard copy. What languages and skill sets will I need to accomplish this project?

  • Templates vs. coded HTML

    - by Alan Harris-Reid
    I have a web-app consisting of some html forms for maintaining some tables (SQlite, with CherryPy for web-server stuff). First I did it entirely 'the Python way', and generated html strings via. code, with common headers, footers, etc. defined as functions in a separate module. I also like the idea of templates, so I tried Jinja2, which I find quite developer-friendly. In the beginning I thought templates were the way to go, but that was when pages were simple. Once .css and .js files were introduced (not necessarily in the same folder as the .html files), and an ever-increasing number of {{...}} variables and {%...%} commands were introduced, things started getting messy at design-time, even though they looked great at run-time. Things got even more difficult when I needed additional javascript in the or sections. As far as I can see, the main advantages of using templates are: Non-dynamic elements of page can easily be viewed in browser during design. Except for {} placeholders, html is kept separate from python code. If your company has a web-page designer, they can still design without knowing Python. while some disadvantages are: {{}} delimiters visible when viewed at design-time in browser Associated .css and .js files have to be in same folder to see effects in browser at design-time. Data, variables, lists, etc., must be prepared in advanced and either declared globally or passed as parameters to render() function. So - when to use 'hard-coded' HTML, and when to use templates? I am not sure of the best way to go, so I would be interested to hear other developers' views. TIA, Alan

  • TeamCity and pending Git merge branch commit keeps build with failed tests

    - by Vladimir
    We use TeamCity for continuous integration and Git for source control. Generally it works pretty well - convenient, modern and good us quick feedback when tests fails. There is a strange behavior related to Git merge specifics. Here are steps of the case: First developer pulls from master repo. Second developer pulls from master repo. First developer makes commit A locally. Second developer makes commit B locally; Second developer pushes commit B. First developer want to push commit A but unable because he have to pull commit B first. First developer pull's from remote reposity. First developer pushes commit A and generated merge branch commit. The history of commits in master repo is following: B second developer A first developer merge branch first developer. Now let's assume that Second Developer fixed some failing tests in his commit B. What TeamCity will do is following: Commit B arrives - TeamCity makes build #1 with all tests passed Commit A arrives - TeamCity makes build #2 (without commit B) test bar becomes Red! TeamCity thought that Pending "Merge Branch" commit doesn't contain any changes (any new files) - but it actually does contain the merge of commit B, so the TeamCity don't want to make new build here and make tests green. Here are two problems: 1. In our case we have failed tests returning back in second commit (commit A) 2. TeamCity don't want to make a new build and make tests back green. Does anybody know how to fix both of this problems. I consider some reasonable general approach.

  • How does Subsonic handle connections?

    - by Quintin Par
    In Nhibernate you start a session by creating it during a BeginRequest and close at EndRequest public class Global: System.Web.HttpApplication { public static ISessionFactory SessionFactory = CreateSessionFactory(); protected static ISessionFactory CreateSessionFactory() { return new Configuration() .Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "hibernate.cfg.xml")) .BuildSessionFactory(); } public static ISession CurrentSession { get{ return (ISession)HttpContext.Current.Items["current.session"]; } set { HttpContext.Current.Items["current.session"] = value; } } protected void Global() { BeginRequest += delegate { CurrentSession = SessionFactory.OpenSession(); }; EndRequest += delegate { if(CurrentSession != null) CurrentSession.Dispose(); }; } } What’s the equivalent in Subsonic? The way I understand, Nhibernate will close all the connections at endrequest. Reason: While trouble shooting some legacy code in a Subsonic project I get a lot of MySQL timeouts,suggesting that the code is not closing the connections MySql.Data.MySqlClient.MySqlException: error connecting: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.

  • web service - client classes

    The web service that I implemented is up and running, when I try to run the client I get the following error with regard to the classes that were generated using wsimport, Caused by: java.security.PrivilegedActionException: com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 4 counts of IllegalAnnotationExceptions Two classes have the same XML type name "{http://server.agency.hw2/}userJoined".

  • Why can't Doctrine retrieve my model data?

    - by scottm
    So, I'm trying to use Doctrine to retrieve some data. I have some basic code like this: $conn = Doctrine_Manager::connection(CONNECTION_STRING); $site = Doctrine_Core::getTable('Site')->find('00024'); echo $site->SiteName; However, this keeps throwing a SQL error that 'column siteid does not exist'. When I look at the exception the SQL query is this (you can see the error is that the inner_tbl alias for siteid is set to s__siteid, so querying inner_tabl.siteid is what's broken): SELECT TOP 1 [inner_tbl].[siteid] AS [s__siteid] FROM (SELECT TOP 1 [s].[siteid] AS [s__siteid], [s].[name] AS [s__name], [s].[address] AS [s__address], [s].[city] AS [s__city], [s].[zip] AS [s__zip], [s].[state] AS [s__state], [s].[region] AS [s__region], [s].[callprocessor] AS [s__callprocessor], [s].[active] AS [s__active], [s].[dateadded] AS [s__dateadded] FROM [Sites] [s] WHERE ([s].[siteid] = '00024') ) AS [inner_tbl] Why is the query being generated this way?

  • Blueprint CSS & Boks: strange behavior with prepend and append in FF and Chrome

    - by Shyam
    Hi, I am working a bit with Blueprint CSS framework and I stumbled upon Boks. I am pretty unfamiliar with the BPCSS framework, but it seems that when using prepend and append, Firefox and Chrome (both) are not liking the input. I generated the code from Boks and for my newbe eye-sight, I can't directly see what went wrong in the export. Even though the span-sizes are correct, they are mutated :S Please help me! <div class="container showgrid"> <!-- first row --> <div class="span-3 prepend-2" id="bar-menuitems"> </div> <div class="span-6 prepend-4" id="banner-logo"> </div> <div class="span-3 prepend-4 append-2 last" id="bar-socialmedia"> </div> <!-- second row --> <div class="clear span-20 prepend-2 append-2 last" id="pane-graphics"> </div> <!-- third row --> <div class="clear span-5 prepend-2" id="banner-xx1"> </div> <div class="span-5" id="banner-xx2"> </div> <div class="span-5" id="banner-xx3"> </div> <div class="span-5 append-2 last" id="banner-xx4"> </div> <!-- last row --> <div class="clear span-6 prepend-9 append-9 last" id="bar-footer"> </div> </div>

  • Optional route parameters in ASP.NET 4 RTM no longer work as before

    - by Simon_Weaver
    I upgraded my project to ASP.NET 4 RTM with ASP.NET MVC 2.0 RTM today. I was previously using ASP.NET 3.5 with ASP.NET MVC 2.0 RTM. Some of my routes don't work suddenly and I don't know why. I'm not sure if something changed between 3.5 and 4.0 - or if this was a regression type issue in the 4.0 RTM. (I never previously tested my app with 4.0). I like to use Url.RouteUrl("route-name", routeParams) to avoid ambiguity when generating URLs. Here's my route definition for a gallery page. I want imageID to be optional (you get a thumbnail page if you don't specify it). // gallery id routes.MapRoute( "gallery-route", "gallery/{galleryID}/{imageID}/{title}", new { controller = "Gallery", action = "Index", galleryID = (string) null, imageID = (string) null, title = (string) null} ); In .NET 3.5 / ASP.NET 2.0 RTM / IIS7 Url.RouteUrl("gallery-route", "cats") => /gallery/cats Url.RouteUrl("gallery-route", "cats", 4) => /gallery/cats/4 Url.RouteUrl("gallery-route", "cats", 4, "tiddles") => /gallery/cats/4/tiddles In .NET 4.0 RTM / ASP.NET 2.0 RTM / IIS7 Url.RouteUrl("gallery-route", "cats") => null Url.RouteUrl("gallery-route", "cats", 4) => /gallery/cats/4 Url.RouteUrl("gallery-route", "cats", 4, "tiddles") => /gallery/cats/4/tiddles Previously I could supply only the galleryID and everything else would be ignored in the generated URL. But now it's looking like I need to specify all the parameters up until title - or it gives up in determining the URL. Incoming URLs work fine for /gallery/cats and that is correctly mapped through this rule with imageID and title both being assigned null in my controller. I also tested the INCOMING routes with http://haacked.com/archive/2008/03/13/url-routing-debugger.aspx and they all work fine.

  • How to use Svn Version Task to set the Version of a vb project

    - by SchlaWiener
    I have a Visual Studio 2008 Solution where the main output exe is a VB.Net Winforms exe which has several VB.Net and C# dll's linked from the same solution. The whole solution is under version control with subversion. Now I want to automagically update by generated files with the current svn revision number. For this purpose I found this neat project: http://svnversiontasks.codeplex.com/ You also need the MSBuild.Communuity.Tasks for this to work. There was a msbuild example on how to update the rev number for every single project in your solution which I use: <Import Project="$(MSBuildExtensionsPath)\SvnTools.Targets\SvnTools.Tasks.VersionManagement.Tasks" /> <Target Name="build"> <CreateItem Include="../**/AssemblyInfo.vb;../**/AssemblyInfo.cs;../**/Properties/AssemblyInfo.cs"> <Output TaskParameter="Include" ItemName="AssemblyInfoFiles" /> </CreateItem> <CreateItem Include="../**/*.vdproj;*.vdproj"> <Output TaskParameter="Include" ItemName="DeploymentProjectFiles" /> </CreateItem> <UpdateVersion AssemblyInfoFiles="@(AssemblyInfoFiles)" DeploymentProjectFiles="@(DeploymentProjectFiles)" Format="yyyy.mm.dd.rev" /> <Exec Command="&quot;$(VS90COMNTOOLS)..\IDE\devenv&quot; ..\MyApp.sln /build" /> <RevertVersionChange AssemblyInfoFiles="@(AssemblyInfoFiles)" DeploymentProjectFiles="@(DeploymentProjectFiles)" /> </Target> I modified the original file to also include the AssemblyInfo.vb file and saved it as a msbuild.proj file. However if I execute msbuild from the console I see that the C# projects are updated (I can also confirm that from the properties of the output dll but my vb project remains unchanged: Reverting version number change: ../App1\AssemblyInfo.vb Updating version number (to rev 0) for file: ../App1\AssemblyInfo.vb D:\Source\MyApp\MyAppDeploy\MyAppDeploy.csproj : warning : Version attribute not found, file not updated. Reverting version number change: ../App2\Properties\AssemblyInfo.cs Updating version number (to rev 0) for file: ../App2\Properties\AssemblyInfo.cs Successfully updated file. Maybe the task does not support VB.Net. But maybe someone has a solution for this...

  • Learning AES: the KeyBytes

    - by Tom Brito
    I got the following example from here: import java.security.Security; import javax.crypto.Cipher; import javax.crypto.spec.SecretKeySpec; public class MainClass { public static void main(String[] args) throws Exception { Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); byte[] input = "www.java2s.com".getBytes(); byte[] keyBytes = new byte[] { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17 }; SecretKeySpec key = new SecretKeySpec(keyBytes, "AES"); Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding", "BC"); System.out.println(new String(input)); // encryption pass cipher.init(Cipher.ENCRYPT_MODE, key); byte[] cipherText = new byte[cipher.getOutputSize(input.length)]; int ctLength = cipher.update(input, 0, input.length, cipherText, 0); ctLength += cipher.doFinal(cipherText, ctLength); System.out.println(new String(cipherText)); System.out.println(ctLength); // decryption pass cipher.init(Cipher.DECRYPT_MODE, key); byte[] plainText = new byte[cipher.getOutputSize(ctLength)]; int ptLength = cipher.update(cipherText, 0, ctLength, plainText, 0); ptLength += cipher.doFinal(plainText, ptLength); System.out.println(new String(plainText)); System.out.println(ptLength); } } I imagine that the byte[] keyBytes should be random generated, so I gone to test the max size before do it. When adding one more byte 0x18 to the array, the exception raised: InvalidKeyException: Key length not 128/192/256 bits. But the original 18 bytes (from 0 to 17) are not multiple of nither 128, 192 or 256. I would like to understand the math here.. can anyone explain me? Thanks!

  • symfony get data from array

    - by iggnition
    Hi, I'm trying to use an SQL query to get data from my database into the template of a symfony project. my query: SQL: SELECT l.loc_id AS l__loc_id, l.naam AS l__naam, l.straat AS l__straat, l.huisnummer AS l__huisnummer, l.plaats AS l__plaats, l.postcode AS l__postcode, l.telefoon AS l__telefoon, l.opmerking AS l__opmerking, o.org_id AS o__org_id, o.naam AS o__naam FROM locatie l LEFT JOIN organisatie o ON l.org_id = o.org_id This is generated by this DQL: DQL: $this->q = Doctrine_Query::create() ->select('l.naam, o.naam, l.straat, l.huisnummer, l.plaats, l.postcode, l.telefoon, l.opmerking') ->from('Locatie l') ->leftJoin('l.Organisatie o') ->execute(); But now when i try to acces this data in the template by either doing: <?php foreach ($q as $locatie): ?> <?php echo $locatie['o.naam'] ?> or <?php foreach ($q as $locatie): ?> <?php echo $locatie['o__naam'] ?> i get the error from symfony: 500 | Internal Server Error | Doctrine_Record_UnknownPropertyException Unknown record property / related component "o__naam" on "Locatie" Does anyone know what is going wrong here? i dont know how to call the value from the array if the names in both query's dont work.

  • Question about registering COM server and Add Reference to it in a C# project

    - by smwikipedia
    I build a COM server in raw C++, here is the procedure: (1) write an IDL file to define the interface and library. (2) use msidl.exe to compile the IDL file to necessary .h, .c, .tlb files. (3) implement the COM server in C++ and build a .dll file. (4) add the following registry entris: [HKEY_CLASSES_ROOT\RawComCarLib.ComCar.1\CurVer] @="RawComCarLib.ComCar.1" ;CLSID [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}] @="RawComCarLib.ComCar.1" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\InprocServer32] @="D:\com\Project01.dll" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\ProgID] @="RawComCarLib.ComCar.1" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\TypeLib] @="{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}" ;TypeLib [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}] [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0] @="Car Server Type Lib" [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0] [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0\win32] @="D:\com\Project01.tlb" [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\FLAGS] @="0" [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0\win32] @="C:\Windows\System32\msdatsrc.tlb" (5) I try to add reference to the COM by click the Add Reference in the C# project. (6) In the COM tab, I saw my "Car Server Type Lib", it's ok until now. I try to use the Object Browser to browse my COM lib, but the Visual Studio said "the following components could not be browsed", and I noticed that there's no new reference added to the list in the C# project Reference. I can use the tlbimp.exe to generate a interop.CarCom.dll, and then use the COM through this interop dll, but I want this interop assembly to be generated automatically when I just add reference to the COM. Could someone tell me what's wrong? Many thanks.

So I'm working in the interface but I get error when I click on the button I directs me to the signup page can somebody please help me with this error this is the code of the mainuserinterface.java for the mainuserinterface.xml file where the button resides. and the signupform.class is the java file for the next activity triggered when the button is clicked the error I receive is the application is unexpectedly stopped.. Hope I make it clear for you guys package com.mohammed.watzIslam; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; public class mainuserinterface extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.mainuserinterface); // this is the button where I receive errors when I click Button forum = (Button) findViewById(R.id.next); forum.setOnClickListener(new View.OnClickListener() { public void onClick(View view){ Intent myIntent = new Intent (view.getContext(), signupform.class); startActivityForResult (myIntent, 0); } }); //these two button still not directing to any next activity yet Button button1 = (Button) findViewById(R.id.next); forum.setOnClickListener(new View.OnClickListener() { public void onClick(View view){ Intent myIntent1 = new Intent (view.getContext(), signupform.class); startActivityForResult (myIntent1, 0); } }); Button button2 = (Button) findViewById(R.id.next); forum.setOnClickListener(new View.OnClickListener() { public void onClick(View view){ Intent myIntent2 = new Intent (view.getContext(), signupform.class); startActivityForResult (myIntent2, 0); } }); } }

  • What is the correct date format for a Date column in YUI DataTable ?

    - by giulio
    I have produced a data table. All the columns are sortable. It has a date in one column which I formatted dd/mm/yyyy hh:mm:ss . This is different from the default format as defined in the doco, but I should be able to define my own format for non-american formats. (See below) The DataTable class provides a set of built-in static functions to format certain well-known types of data. In your Column definition, if you set a Column's formatter to YAHOO.widget.DataTable.formatDate, that function will render data of type Date with the default syntax of "MM/DD/YYYY". If you would like to bypass a built-in formatter in favor of your own, you can point a Column's formatter to a custom function that you define. The table is generated from HTML Markup, so the data is held within "" tags. This gives me some more clues about compatible string dates for javascript: In general, the RecordSet expects to hold data in native JavaScript types. For instance, a date is expected to be a JavaScript Date instance, not a string like "4/26/2005" in order to sort properly. Converting data types as data comes into your RecordSet is enabled through the parser property in the fields array of your DataSource's responseSchema I suspect that the I'm missing something in the date format. So what is an acceptable string date for javascript, that Yui dataTable will recognise, given that I want format it as "dd/mm/yyyy hh:mm:ss" ?

  • Invalidating Memcached Keys on save() in Django

    - by Zack
    I've got a view in Django that uses memcached to cache data for the more highly trafficked views that rely on a relatively static set of data. The key word is relatively: I need invalidate the memcached key for that particular URL's data when it's changed in the database. To be as clear as possible, here's the meat an' potatoes of the view (Person is a model, cache is django.core.cache.cache): def person_detail(request, slug): if request.is_ajax(): cache_key = "%s_ABOUT_%s" % settings.SITE_PREFIX, slug # Check the cache to see if we've already got this result made. json_dict = cache.get(cache_key) # Was it a cache hit? if json_dict is None: # That's a negative Ghost Rider person = get_object_or_404(Person, display = True, slug = slug) json_dict = { 'name' : person.name, 'bio' : person.bio_html, 'image' : person.image.extra_thumbnails['large'].absolute_url, } cache.set(cache_key) # json_dict will now exist, whether it's from the cache or not response = HttpResponse() response['Content-Type'] = 'text/javascript' response.write(simpljson.dumps(json_dict)) # Make sure it's all properly formatted for JS by using simplejson return response else: # This is where the fully templated response is generated What I want to do is get at that cache_key variable in it's "unformatted" form, but I'm not sure how to do this--if it can be done at all. Just in case there's already something to do this, here's what I want to do with it (this is from the Person model's hypothetical save method) def save(self): # If this is an update, the key will be cached, otherwise it won't, let's see if we can't find me try: old_self = Person.objects.get(pk=self.id) cache_key = # Voodoo magic to get that variable old_key = cache_key.format(settings.SITE_PREFIX, old_self.slug) # Generate the key currently cached cache.delete(old_key) # Hit it with both barrels of rock salt # Turns out this doesn't already exist, let's make that first request even faster by making this cache right now except DoesNotExist: # I haven't gotten to this yet. super(Person, self).save() I'm thinking about making a view class for this sorta stuff, and having functions in it like remove_cache or generate_cache since I do this sorta stuff a lot. Would that be a better idea? If so, how would I call the views in the URLconf if they're in a class?

  • Getting SSL to work with Apache/Passenger on OSX

    - by jonnii
    I use apache/passenger on my development machine, but need to add SSL support (something which isn't exposed through the control panel). I've done this before in production, but for some reason I can't seem to get it work on OSX. The steps I've followed so far are from a default apache osx install: Install passenger and passenger preference pane. Add my rails app (this works) Create my ca.key, server.crt and server.key as detailed on the apple website. At this point I need to start editing the apache configs, so I added: # Apache knows to listen on port 443 for ssl requests. Listen 443 Listen 80 I thought I'd try editing the passenger pref pane generated config first to get everything working, when I add: It starts off looking like this <VirtualHost *:80> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <Directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </Directory> </VirtualHost> I then append this: <VirtualHost *:443> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </directory> # SSL Configuration SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP SSLOptions +FakeBasicAuth +ExportCertData +StdEnvVars +StrictRequire #Self Signed certificates SSLCertificateFile /private/etc/apache2/ssl.key/server.crt SSLCertificateKeyFile /private/etc/apache2/ssl.key/server.key SSLCertificateChainFile /private/etc/apache2/ssl.key/ca.crt SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 </VirtualHost> The files referenced all exist (I doubled checked that), but now when I restart my apache I can't even get to myapp.local. However apache can still server the default page when I click on it in the sharing preference panel. Any help would be greatly appreciated.

  • Write binary data as a response in an ASP.NET MVC web control

    - by Lou Franco
    I am trying to get a control that I wrote for ASP.NET to work in an ASP.NET MVC environment. Normally, the control does the normal thing, and that works fine Sometimes it needs to respond by clearing the response, writing an image to the response stream and changing the content type. When you do this, you get an exception "OutputStream is not available when a custom TextWriter is used". If I were a page or controller, I see how I can create custom responses with binary data, but I can't see how to do this from inside a control's render functions. To simplify it -- imagine I want to make a web control that renders to: <img src="pageThatControlIsOn?controlImage"> And I know how to look at incoming requests and recognize query strings that should be routed to the control. Now the control is supposed to respond with a generated image (content-type: image/png -- and the encoded image). In ASP.NET, we: Response.Clear(); Response.OutputStream.Write(thePngData); // this throws in MVC // set the content type, etc Response.End(); How am I supposed to do that in an ASP.NET MVC control?

  • Issues with Rails, Amazon S3, and protected URLs

    - by Shpigford
    So I followed this little tutorial about protecting downloads of files that are uploaded to Amazon S3 with Paperclip. When I've developed locally, it's worked fine, but since pushing the exact same code to a production server...I now get this error from Amazon when I try to access the files: <Error> <Code>InvalidArgument</Code> <Message>Either the Signature query string parameter or the Authorization header should be specified, not both</Message> <ArgumentValue>Basic dGVjaHVrdWxlbGU6ZWxlbHVrdWhjZXQ=</ArgumentValue> <ArgumentName>Authorization</ArgumentName> <RequestId>F6E455857C54F95A</RequestId> <HostId>X4QA2pw9wpHtJtJ2T8qxCyINjq4PLHQVF4VrlYjpX7Ayh694BgQprh5p8H7NRCAt</HostId> </Error> Example URL: http://s3.amazonaws.com/media.example.com/assets/videos/1/original.mov?AWSAccessKeyId=MY_ACCESS_KEY&Expires=1271972624&Signature=7wWH2WYHPO0o9szwPJbimUMqAig%3D That URL is generated using AWS::S3::S3Object.url_for using the aws-s3 gem. So...not even sure where to start. The fact that it works fine when the app is running locally but not when in production really doesn't make sense. The production server is running Ubuntu 8.04.4 LTS (Hardy).

  • semi dynamic cdn

    - by dwi kristianto
    i'm developing couple of websites using php (directory script, etc.) and wordpress as cms. i need to improve its performance, by using cdn for static files (css, js, images). the problem is, css and javascript files are generated on the fly. i did that due to yahoo and some expert advice to combine the files into one file. also changing basic color of css files. for the time being, i use couple of small vps but still its not fast enough. i already contact maxcdn and the support guy said that they dont have such kind of services. what i need is: a cdn that will serve the request from user/visitor and there's no file in local disk, the cdn will redirect/fetch it from another domain/server. in vps, it could be done easily using combination of .htaccess and php, but NOT in the cdn. most of cdn only support purely static files. is there any such cdn that will server semi-dynamic files?

  • How can I attach a file using Wordpress custom fields / meta boxes?

    - by shipshape
    I am using Wordpress's add_meta_box() function to add customized meta fields to the Add New Post page, like this. I want one of these fields to allow the user to upload a file, so that a single image, pdf, audio file, or video can be associated with the post. The closest example I've seen is this one. Unfortunately it does not suit my needs, as I want my file to be processed by Wordpress's Media Uploader - so it should appear in the Media Library afterwards, and thumbnails should be generated according to the Media settings. I think ideally there would be a way to tap into Wordpress's existing Add Media dialog, and simply output the URL of the uploaded file into a text box, but I don't see how to do that. This question is similar, but the answers are a little clunky - I would like to keep this super simple for my end users. How can I accomplish this? Please do not recommend plugins such as Flutter or Magic Fields - I have tried these and they do not suit my purposes (I want the images to be processed by Wordpress's Media Uploader). I am using Wordpress 3.0-alpha. Thanks!

  • In Seam what's the difference between injected EntityManager and getEntityManager from EntityHome

    - by Navi
    I am testing a Seam application using the needle test API. In my code I am using the getEntityManager() method from EntityHome. When I run the unit tests against an in memory database I get the following exception: java.lang.IllegalStateException: No application context active at org.jboss.seam.Component.forName(Component.java:1945) at org.jboss.seam.Component.getInstance(Component.java:2005) at org.jboss.seam.Component.getInstance(Component.java:1983) at org.jboss.seam.Component.getInstance(Component.java:1977) at org.jboss.seam.Component.getInstance(Component.java:1972) at org.jboss.seam.framework.Controller.getComponentInstance(Controller.java:272) at org.jboss.seam.framework.PersistenceController.getPersistenceContext(PersistenceController.java:20) at org.jboss.seam.framework.EntityHome.getEntityManager(EntityHome.java:177) etc .. I can resolve some of these errors by injecting the EntityManager with @In EntityManager entityManager; Unfortunately the persist method of EntityHome also calls the getEntityManager. This means a lot of mocks or rewriting the code somehow. Is there any workaround and why is this exception thrown anyway? I am using Seam 2.2.0 GA by the way. There is nothing special about the components. They are generated by seam-gen. The test is performed with in memory database - I followed the examples in http://jbosscc-needle.sourceforge.net/jbosscc-needle/1.0/db-util.html.

  • haskell: a data structure for storing ascending integers with a very fast lookup

    - by valya
    Hello! (This question is related to my previous question, or rather to my answer to it.) I want to store all qubes of natural numbers in a structure and look up specific integers to see if they are perfect cubes. For example, cubes = map (\x -> x*x*x) [1..] is_cube n = n == (head $ dropWhile (<n) cubes) It is much faster than calculating the cube root, but It has complexity of O(n^(1/3)) (am I right?). I think, using a more complex data structure would be better. For example, in C I could store a length of an already generated array (not list - for faster indexing) and do a binary search. It would be O(log n) with lower ?oefficient than in another answer to that question. The problem is, I can't express it in Haskell (and I don't think I should). Or I can use a hash function (like mod). But I think it would be much more memory consuming to have several lists (or a list of lists), and it won't lower the complexity of lookup (still O(n^(1/3))), only a coefficient. I thought about a kind of a tree, but without any clever ideas (sadly I've never studied CS). I think, the fact that all integers are ascending will make my tree ill-balanced for lookups. And I'm pretty sure this fact about ascending integers can be a great advantage for lookups, but I don't know how to use it properly (see my first solution which I can't express in Haskell).

  • Spelling correction for data normalization in Java

    - by dareios
    I am looking for a Java library to do some initial spell checking / data normalization on user generated text content, imagine the interests entered in a Facebook profile. This text will be tokenized at some point (before or after spell correction, whatever works better) and some of it used as keys to search for (exact match). It would be nice to cut down misspellings and the like to produce more matches. It would be even better if the correction would perform well on tokens longer than just one word, e.g. "trinking coffee" would become "drinking coffee" and not "thinking coffee". I found the following Java libraries for doing spelling correction: JAZZY does not seem to be under active development. Also, the dictionary-distance based approach seems inadequate because of the use of non-standard language in social network profiles and multi-word tokens. APACHE LUCENE seems to have a statistical spell checker that should be much more suited. Question here would how to create a good dictionary? (We are not using Lucene otherwise, so there is no existing index.) Any suggestions are welcome!
