• django powering multiple shops from one code base on a single domain

  - by imanc

  Hey, I am new to django and python and am trying to figure out how to modify an existing app to run multiple shops through a single domain. Django's sites middleware seems inappropriate in this particular case because it manages different domains, not sites run through the same domain, e.g. : domain.com/uk domain.com/us domain.com/es etc. Each site will need translated content - and minor template changes. The solution needs to be flexible enough to allow for easy modification of templates. The forms will also need to vary a bit, e.g minor variances in fields and validation for each country specific shop. I am thinking along the lines of the following as a solution and would love some feedback from experienced django-ers: In short: same codebase, but separate country specific urls files, separate templates and separate database Create a middleware class that does IP localisation, determines the country based on the URL and creates a database connection, e.g. /au/ will point to the au specific database and so on. in root urls.py have routes that point to a separate country specific routing file, e..g (r'^au/',include('urls_au')), (r'^es/',include('urls_es')), use a single template directory but in that directory have a localised directory structure, e.g. /base.html and /uk/base.html and write a custom template loader that looks for local templates first. (or have a separate directory for each shop and set the template directory path in middleware) use the django internationalisation to manage translation strings throughout slight variances in forms and models (e.g. ZA has an ID field, France has 'door code' and 'floor' etc.) I am unsure how to handle these variations but I suspect the tables will contain all fields but allowing nulls and the model will have all fields but allowing nulls. The forms will to be modified slightly for each shop. Anyway, I am keen to get feedback on the best way to go about achieving this multi site solution. It seems like it would work, but feels a bit "hackish" and I wonder if there's a more elegant way of getting this solution to work. Thanks, imanc

• Why won't VS2010 RC use my existing types when I add a service reference?

  - by Johan Driessen

  I have a huge problem getting services references in VS2010 RC to use existing assemblies. Even though I have a class library with all the data contracts (classes marked with DataContract and properties with DataMember) that is shared between the service project and the consuming project (which is a class library), when I add a service reference, the data contracts are regenerated withing the service reference instead of using the existing types. When I was using VS2010 beta 2, this worked fine, and I have existing service references using the very same data contracts. But if I add a new service reference, or even update an old one, it won't use the existing types anymore. I have made a mini-test-solution, with one service, one data contract type and one console app as a consumer (all in the same solution), and there it seems to work, but that's no great comfort to me. Is there any way to see why it can't use the existing types? Edit to clearify. It works to generate the proxy classes with svcutil.exe, and point to the data contracts dll, like this: svcutil.exe http://localhost/MyService.svc /reference:[Path To DataContracts]\DataContracts.dll /n:*,MyProject.MyServiceReference /ct:System.Collections.Generic.List`1 The question is, what possible reason could there be for Visual Studio to generate its own datacontracts instead of using the existing ones even though the "reuse" checkbox is checked and the datacontracts assembly is referenced.

• How to verify the SSL connection when calling a URI?

  - by robertokl

  Hello, I am developing a web application that is authenticated using CAS (A single-sign-on solution: http://www.ja-sig.org/wiki/display/CAS/Home). For security reasons, I need two things to work: The communication between CAS and my application needs to be secure My application needs to accept the certification coming from CAS, so that I can guarantee that the CAS responding is the real CAS server This is what I got so far: uri = URI.parse("https://www.google.com/accounts") https = Net::HTTP.new(uri.host, uri.port) https.use_ssl = (uri.scheme == 'https') https.verify_mode = (OpenSSL::SSL::VERIFY_PEER) raw_res = https.start do |conn| conn.get("#{uri.path}?#{uri.query}") end This works just great in Mac OS X. When I try to reach an insecure URI, it raises an exception, and when I try to reach a secure URI, it allows me normally, just like expected. The problem starts when I deploy my application on my Linux server. I tried in both Ubuntu and Red Hat. Independent of what URI I try to reach, it always raises this exception: OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:553:in `do_start' from /usr/local/lib/ruby/1.8/net/http.rb:542:in `start' from (irb):7 I think this have something to do with my installed OpenSSL package, but I can't be sure. This are my installed OpenSSL packages: openssl.x86_64 0.9.8e-12.el5 installed openssl-devel.x86_64 0.9.8e-12.el5 installed I tried using HTTParty as well, but it just ignores the SSL certificate. I hope someone can help me, or tell me about a gem that works the way I need. Thanks.

• Why is there unreachable code here?

  - by Richard

  I am writing a c# app and want to output error messages to either the console or a messagebox (Depending on the app type: enum AppTypeChoice { Console, Windows } ), and also control wether the app keeps running or not ( bool StopOnError ). I came up with this method that will check all the criteria, but I'm getting an "unreachable code detected" warning. I can't see why! Here is the whole method (Brace yourselves for some hobbyist code!) public void OutputError(string message) { string standardMessage = "Something went WRONG!. [ But I'm not telling you what! ]"; string defaultMsgBoxTitle = "Aaaaarrrggggggggggg!!!!!"; string dosBoxOutput = "\n\n*** " + defaultMsgBoxTitle + " *** \n\n Message was: '" + message + "'\n\n"; AppTypeChoice appType = DataDefs.AppType; DebugLevelChoice level = DataDefs.DebugLevel; // Decide how much info we should give out here... if (level != DebugLevelChoice.None) { // Give some info.... if (appType == AppTypeChoice.Windows) MessageBox.Show(message, defaultMsgBoxTitle, MessageBoxButtons.OK, MessageBoxIcon.Error); else Console.WriteLine(dosBoxOutput); } else { // Be very secretive... if (appType == AppTypeChoice.Windows) MessageBox.Show(standardMessage, defaultMsgBoxTitle, MessageBoxButtons.OK, MessageBoxIcon.Error); else Console.WriteLine(standardMessage); } // Decide if app falls over or not.. if (DataDefs.StopOnError == true) Environment.Exit(0); // UNREACHABLE CODE HERE } Also, while I have your attention, to get the app type, I'm just using a constant at the top of the file (ie. AppTypeChoice.Console in a Console app etc) - is there a better way of doing this (i mean finding out in code if it is a DOS or Windows app)? Also, I noticed that I can use a messagebox with a fully-qualified path in a Console app...How bad is is to do that ( I mean, will I get tarred and feathered when other developers see it?!) Thanks for your help

I have tried both and gotten the same error. If anyone knows why this is happening help is really appreciated.

• Sinatra application running on Dreamhost suddenly not working

  - by jbrennan

  My Sinatra application was running fine on Dreamhost until a few days ago (I'm not sure precisely when it went bad). Now when I visit my app I get this error: can't activate rack (~> 1.1, runtime) for ["sinatra-1.1.2"], already activated rack-1.2.1 for [] I have no idea how to fix this. I've tried updating all my gems, then touching the app/tmp/restart.txt file, but still no fix. I hadn't touched any files of my app, nor my Dreamhost account. It just busted on its own (my guess is DH changed something on their server which caused the bust). When I originally deployed my app, I had to go through some hoops to get it working, and I seem to think I was using gems in a custom location, but I can't remember exactly where or how. I don't know my way around Rack/Passenger very well. Here's my config.ru: (mostly grafted from around the web, I don't fully understand it) ENV['RACK_ENV'] = 'development' if ENV['RACK_ENV'].empty? #### Make sure my own gem path is included first ENV['GEM_HOME'] = "#{ENV['HOME']}/.gems" ENV['GEM_PATH'] = "#{ENV['HOME']}/.gems:" require 'rubygems' Gem.clear_paths ## NB! key part require 'sinatra' set :env, :production disable :run require 'MY_APP_NAME.rb' run Sinatra::Application

• Beyond the @Produces annotation, how does Jersey (JAX-RS) know to treat a POJO as a specific mime ty

  - by hal10001

  I see a lot of examples for Jersey that look something like this: public class ItemResource { @GET @Path("/items") @Produces({"text/xml", "application/json"}) public List<Item> getItems() { List<Item> items = new ArrayList<Item>(); Item item = new Item(); item.setItemName("My Item Name!"); items.add(item); return items; } } But then I have trouble dissecting Item, and how Jersey knows how to translate an Item to either XML or JSON. I've seen very basic examples that just return a String of constructed HTML or XML, which makes more sense to me, but I'm missing the next step. I looked at the samples, and one of them stood out (the json-from-jaxb sample), since the object was marked with these types of annotations: @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "", propOrder = { "flight" }) @XmlRootElement(name = "flights") I'm looking for tutorials that cover this "translation" step-by-step, or an explanation here of how to translate a POJO to output as a specific mime type. Thanks!

• How to modify/replace option set file when building from command line?

  - by Heinrich Ulbricht

  I build packages from a batch file using commands like: msbuild ..\lib\Package.dproj /target:Build /p:config=%1 The packages' settings are dependent on an option set: <Import Project="..\optionsets\COND_Defined.optset" Condition="'$(Base)'!='' And Exists('..\optionsets\COND_Defined.optset')"/> This option set defines a conditional symbol many of my packages depend on. The file looks like this: <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <DCC_Define>CONDITION;$(DCC_Define)</DCC_Define> </PropertyGroup> <ProjectExtensions> <Borland.Personality>Delphi.Personality.12</Borland.Personality> <Borland.ProjectType>OptionSet</Borland.ProjectType> <BorlandProject> <Delphi.Personality/> </BorlandProject> <ProjectFileVersion>12</ProjectFileVersion> </ProjectExtensions> </Project> Now I need two builds: one with the condition defined and one without. My attack vector would be the option set file. I have some ideas on what to do: write a program which modifies the option set file, run this before batch build fiddle with the project files and modify the option set path to contain an environment variable, then have different option sets in different locations But before starting to reinvent the wheel I'd like to ask how you would tackle this task? Maybe there are already means meant to support such a case (like certain command line switches, things I could configure in Delphi or batch file magic).

• Rubygems on Debian: Gems won't load (LoadError)

• Need Help with wxPython & pyGame

  - by Xavier

  Hi Guys, I'm actually in need of your help and advice here on my assignment that I am working on. First of all, I was task to do a program that runs langton's ant simulation. For that, I've managed to get the source code (from snippets.dzone.com/posts/show/5143) and edited it accordingly to my requirements. This was done and ran in pygame module extension. In addition, my task requires a GUI to interface for users to run and navigate through the screens effectively with the langton's ant program running. I used wxPython with the help of an IDE called BOA constructor to create the frames, buttons, textboxes, etc. Basically, all the stuff needed in the interfaces. However, I've ran into some problems listed below: Found problem integrating pyGame with wxPython. On this note, I've research the internet for answers and tutorials where I found out from website: wiki.wxpython.org/IntegratingPyGame & aspn.activestate.com/ASPN/Mail/Message/wxpython-users/3178042. I understand from the sites that integrating pyGame with wxPython will be a difficult task where it has caused common problems like the inability to placing other controls into the frames as the pyGame application will cover the entire panel. I really hope that you can clarify my doubts on this and advise me on the path that I should take from here. Therefore, I ask the following questions: Is it feasible to integrate pyGame with wxPython? If it is not feasible to integrate pyGame with wxPython, what other alternatives do I have to create a GUI interface integrating pyGame into it. If so how do I go about? If it is possible to go about integrating pyGame with wxPython, how do I go about doing so? Really need you guys opinion on this.

• Apache - "dynamic" rewrite rule

  - by Christian A. Rasmussen

  Hi there. I'm working on a Zend Framework project where I've stumbled across a bit of a problem. The problem originates from the fact that modules are 2nd class citizens in Zend Framework. In my project, I'd like for each module to have a folder containing files which are to be accessed from the outside - files such as stylesheets, javascripts and images. Now, how is this to be done. With a Zend Framework project I have a folder structure which looks like this: application/ modules/ moduleOne/ public/ stylesheet.css moduleTwo/ moduleThree/ public/ index.php The standard .htaccess file located in the public/ folder holds this: SetEnv APPLICATION_ENV development RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L] The way it works, is that the project's apache DocumentRoot is the public/ folder. All requests gets redirected through the index.php file where Zend Framework's router component takes over. Now, I'm by no means an expert with Apache nor mod_rewrite so pardon me if this is just silly. I imagine that I implement an extra step in the existing rewrite rule so that if I request http://project/public/moduleOne/stylesheet.css it will for instance resolve to /var/www/project/application/modules/moduleOne/public/stylesheet.css. So the steps which need to be done is to check if the first element in the URI is public/ if it is, we take the next segment as the modules name and use that in the path we're trying to resolve to and attempt to serve the file. Is this at all possible or does anyone have a better suggestion? Thank you for your time Christian Rasmussen

• Call WCF Service Through Javascript, AJAX, or JQuery

  - by obautista

  I created a number of standard WCF Services (Service Contract and Host (svc) are in separate assemblies). I fired up a Web Site in IIS to host the Services (i.e., address is http://services:1000/wcfservices.svc). Then in my Web Site project I added the reference. I am able to call the services normally. I am needed to call some of the services client side. Not sure if I should be looking at articles calling WCF services through AJAX, JQuery, or JSON enabled WCF Services. Can anyone provide any thoughts or experience with configuring as such? Some of the changes I made was adding the following to the Operation Contract: [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "SetFoo")] void SetFoo(string Id); Then this above the implementation of the interface: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] Then in the service webconfig I have this (parens are angle brackets): <serviceHostingEnvironment aspNetCompatibilityEnabled="true"> <baseAddressPrefixFilters> <add prefix="http://services:1000/wcfservices.svc/"/>> </baseAddressPrefixFilters> </serviceHostingEnvironment> <serviceHostingEnvironment multipleSiteBindingsEnabled="false" /> Then in the client side I attempted this: <asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server"> <compositeScript> <Scripts> <asp:ScriptReference Path="http://Flixsit:1000/FlixsitWebServices.svc" /> </Scripts> </CompositeScript> </asp:ScriptManagerProxy> I am attempting to call the service like this in javascript: wcfservices.SetFoo(string Id); Nothing is working. If it is idea or a better solution to call JSON enable, JQuery, etc....I am willing to make any changes. Thanks for any suggestions/tips provided....

• Avoiding Service Locator with AutoFac 2

  - by Page Brooks

  I'm building an application which uses AutoFac 2 for DI. I've been reading that using a static IoCHelper (Service Locator) should be avoided. IoCHelper.cs public static class IoCHelper { private static AutofacDependencyResolver _resolver; public static void InitializeWith(AutofacDependencyResolver resolver) { _resolver = resolver; } public static T Resolve<T>() { return _resolver.Resolve<T>(); } } From answers to a previous question, I found a way to help reduce the need for using my IoCHelper in my UnitOfWork through the use of Auto-generated Factories. Continuing down this path, I'm curious if I can completely eliminate my IoCHelper. Here is the scenario: I have a static Settings class that serves as a wrapper around my configuration implementation. Since the Settings class is a dependency to a majority of my other classes, the wrapper keeps me from having to inject the settings class all over my application. Settings.cs public static class Settings { public static IAppSettings AppSettings { get { return IoCHelper.Resolve<IAppSettings>(); } } } public interface IAppSettings { string Setting1 { get; } string Setting2 { get; } } public class AppSettings : IAppSettings { public string Setting1 { get { return GetSettings().AppSettings["setting1"]; } } public string Setting2 { get { return GetSettings().AppSettings["setting2"]; } } protected static IConfigurationSettings GetSettings() { return IoCHelper.Resolve<IConfigurationSettings>(); } } Is there a way to handle this without using a service locator and without having to resort to injecting AppSettings into each and every class? Listed below are the 3 areas in which I keep leaning on ServiceLocator instead of constructor injection: AppSettings Logging Caching

• Powershell - Splitting string into seperate components

  - by TheD

  I am writing a script which will basically do the following: Read from a text file some arguements: DriveLetter ThreeLetterCode ServerName VolumeLetter Integer Eg. W MSS SERVER01 C 1 These values happen to form a folder destination W:\MSS\, and a filename which works in the following naming convention: SERVERNAME_VOLUMELETTER_VOL-b00X-iYYY.spi - Where The X is the Integer above The value Y I need to work out later, as this happens to be the value of the incremental image (backups) and I need to work out the latest incremental. So at the moment -- Count lines in file, and loop for this many lines. $lines = Get-Content -Path PostBackupCheck-Textfile.txt | Measure-Object -Line for ($i=0; $i -le $lines.Lines; $i++) Within this loop I need to do a Get-Content to read off the line I am currently looking at i.e. line 0, line 1, line 2, as there will be multiple lines in the format I wrote at the beginning and split the line into an array, whereby each part of the file, as seen above naming convention, is in a[0], a[1], a[2]. etc The reason for this is because, I need to then sort the folder that contains these, find the latest file, by date, and take the _iXXX.spi part and place this into the array value a[X] so I then have a complete filename to mount. This value will replace iYYY.spi It's a little complex because I also have to make sure when I do a Get-ChildItem with -Include before I sort it all by date, I am only including the filename that matches the arguements fed to it from the text file : So, SERVER01_C_VOL-b001-iYYY.spi and not anything else. i.e. not SERVER01_D_VOL-b001-iYYY.spi Then take the iYYY value from the sort on the Get-ChildItem -Include and place that into the appropriate array item. I've literally no idea where to start, so any ideas are appreciated! Hopefully I've explained in enough detail. I have also placed the code on Pastebin: http://pastebin.com/vtFifTW6 Thanks!

• IO operation taking long time for files in remote server

  - by user841311

  I have files of size 150 MB each in a remote server in a different domain in the network. I am accessing them thorugh UNC path. I want to read the file content and perform a basic string search. When I try reading the files line by line, the operation just don't finish and takes long time, more than 30 minutes. However when I copy those files to my local machine, the same code reads and performs the string search in less than 5 seconds. I don't have .NET framework installed in the server so I have to do this from my machine. I want to perform all this through C# code in .NET framework 3.5 so I don't want to explictly ftp all the files to my machine before performing this operation. Sample Code DirectoryInfo dir = new DirectoryInfo(@strFilePath); FileInfo[] fiArray = dir.getFiles("*.txt"); foreach (FileInfo fi in fiArray) { //reading file content from server takes long time but fast in local machine //perform string search } Let me know if my requirement is not clear. Thanks in advance!

• In IIS6, how to provide authenticated access to static files on remote server

  - by frankadelic

  We have a library of ZIP files that we would like to make available for download at an ASP.NET site. The files are sitting on a NAS device that is accessible from out web farm. Here is our initial strategy: Map an IIS virtual directory to the shared drive at path /zipfiles Users can download the zip files when given the URL However, if users share links to the files, anyone can download them. We would instead like to make use of the ASP.NET forms authentication in our site to validate users' requests before initiating the file transfer. A few problems: A request for a zip file is handled by IIS, not ASP.NET. So it is not subject to forms authentication. In addition, we don't want ASP.NET to handle the request, because it uses up an ASP.NET thread and is not scalable for download of large files. So, configuring the asp.net dll to handle *.zip requests is not an option. Any ideas on this? One idea we've tossed around is this: Initial request for download will be for an ashx handler. This handler will, after authentication, generate a download token which is saved to a database. Then, the user is redirected to the file with token appended in QueryString (e.g. /files/xyz.zip?token=123456789). An ISAPI plugin will be used to check the token. Also, the token will expire after x amount of time. Any thoughts on this? I have not implemented an ISAPI plugin so I'm not sure if this will even work. I would like to avoid custom coding since security is an issue and I'd prefer to use a time-tested solution.

• Unable to find reference to std library math function inside library

  - by Alex Marshall

  Hello, I've got several programs that use shared libraries. Those shared libraries in turn use various standard C libraries. ie Program A and Program B both use Shared Library S. Shared Library S uses std C math. I want to be able to statically link Shared Library S against the standard library, and then statically link Programs A and B against S so that I don't have to be dragging around the library files, because these programs are going to be running on an embedded system running BusyBox 0.61. However, when I try to statically link the programs against Shared Library S, I get an error message from GCC stating : ../lib/libgainscalecalc.a(gainscalecalc.): In function 'float2gs': [path to my C file].c:73: undefined reference to 'log' Can somebody please help me out ?

  I produced a text file and is saved to a location in the project folder. How do I redirect them to the url that contains that text file, so they can download the text file. CreateCSVFile creates the csv file to a file path based on a datatable. Calling: string pth = ("C:\\Work\\PG\\AI Handheld Website\\AI Handheld Website\\Reports\\Files\\report.txt"); CreateCSVFile(data, pth); And the function: public void CreateCSVFile(DataTable dt, string strFilePath) { StreamWriter sw = new StreamWriter(strFilePath, false); int iColCount = dt.Columns.Count; for (int i = 0; i < iColCount; i++) { sw.Write(dt.Columns[i]); if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); // Now write all the rows. foreach (DataRow dr in dt.Rows) { for (int i = 0; i < iColCount; i++) { if (!Convert.IsDBNull(dr[i])) { sw.Write(dr[i].ToString()); } if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); } sw.Close(); Response.WriteFile(strFilePath); FileInfo fileInfo = new FileInfo(strFilePath); if (fileInfo.Exists) { //Response.Clear(); //Response.AddHeader("Content-Disposition", "attachment; filename=" + fileInfo.Name); //Response.AddHeader("Content-Length", fileInfo.Length.ToString()); //Response.ContentType = "application/octet-stream"; //Response.Flush(); //Response.TransmitFile(fileInfo.FullName); } }

• Adding a ServiceReference programmatically during async postback

  - by Oliver

  Is it possible to add a new ServiceReference instance to the ScriptManager on the Page during an asynchronous postback so that subsequently I can use the referenced web service through client side script? I'm trying to do this inside a UserControl that sits inside a Repeater, that's why adding the ScriptReference programmatically during Page_Load does not work here. EDIT 2: This is the code I call from my UserControl which does not do what I expect (adding the ServiceReference to the ScriptManager during the async postback): private void RegisterWebservice(Type webserviceType) { var scm = ScriptManager.GetCurrent(Page); if (scm == null) throw new InvalidOperationException("ScriptManager needed on the Page!"); scm.Services.Add(new ServiceReference("~/" + webserviceType.Name + ".asmx")); } My goal is for my my UserControl to be as unobtrusive to the surrounding application as possible; otherwise I would have to statically define the ServiceReference in a ScriptManagerProxy on the containing Page, which is not what I want. EDIT: I must have been tired when I wrote this post... because I meant to write ServiceReference not ScriptReference. Updated the text above accordingly. Now I have: <asp:ScriptManagerProxy runat="server" ID="scmProxy"> <Services> <asp:ServiceReference Path="~/UsefulnessWebService.asmx" /> </Services> </asp:ScriptManagerProxy> but I want to register the webservice in the CodeBehind.

• C# client to Java web service

  - by tomislavg

  I have received wsdl file from outside company. I'm using VS2005 c#. With wsdl.exe I have created class containing methods and types for the given web service. To connect to the service outside company requires that certificate from the smart card is inputed in the header. I think i have achieved this with service.ClientCertificates.Add("Path to exported cert" - at least for now, after probably later i will take it from Certificate Store When service is called there are three steps that are taken and visible by the Fidller(Web Debugging Proxy)). service is called on the url http://test.company.com/webservice.wsdl service redirects the request to certificate server and pin needs to be inputed to get cookie for the server service is again redirected to url http://test.company.com/webservice.wsdl At point 1. I can see that my request send to the server contains .... but at point 3. i can not see request` just a empty string. The exception is thrown Msg: Possible SOAP version mismatch: Envelope namespace http://schemas.xmlsoap.org/wsdl/ was unexpected. Expecting http://schemas.xmlsoap.org/soap/envelope/. Does somebody have an example how to connect to java web service with certificate and AlowRedirect enabled for the web service? Any ideas what i am doing wrong are more that welcome.

• how to associate the activemq-core.xsd url with the activemq.xsd found in the jar file?

  - by livia

  Hello, Somebody knows how to associate the activemq-core.xsd url with the activemq.xsd found in the jar file (activemq-core-5.2.0.jar)? I dig some solution in internet but didn't work. I'm getting this error: Caused by: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 19 in XML document from class path resource [jms-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'amq:broker'. at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:404) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:342) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:310) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:143) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:178) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:149) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:212) at org.springframework.test.context.support.AbstractGenericContextLoader.loadContext(AbstractGenericContextLoader.java:81) at org.springframework.test.context.support.AbstractGenericContextLoader.loadContext(AbstractGenericContextLoader.java:42) at org.springframework.test.context.TestContext.loadApplicationContext(TestContext.java:173) at org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:197) This shoud me hapening because we remove the URL from the schemaLocation (http://activemq.apache.org/schema/core classpath:activemq.xsd), and we are using localy. But I don't know why XML are not finding the activemq.xsd during the build process. I add the JAR file in the classpath, should not work like that?? Thanks in advance for any help

• Ignore LD_LIBRARY_PATH and stick with library given through -rpath at link time

  - by roe

  I'm sitting in an environment which I have no real control over (it's not just me, so basically, I can't change the environment or it won't work for anyone else), the only thing I can affect is how the binary is built. My problem is, the environment specifies an LD_LIBRARY_PATH containing a libstdc++ which is not compatible with the compiler being used. I tried compiling it statically, but that doesn't seem possible for g++ (version 4.2.3, seems to have been work done in this direction in later versions though which are not available, -static-libstdc++ or something like that). Now I've arrived at using rpath to bake the absolute path name into the executable (would work, all machines it's supposed to run on are identical). Unfortunately it appears as though LD_LIBRARY_PATH takes precedence over rpath (resetting LD_LIBRARY_PATH confirmed that it's able to find the library, but as stated above, LD_LIBRARY_PATH will be set for everyone, and I cannot change that). Is there any way I can make rpath take precedence over LD_LIBRARY_PATH, or are there any other possible solutions to my problem? Note that I'm talking about dynamic linking at runtime, I am able to control the command line at compile and link time. Thanks.

• Git : Failed at pushing to remote server, ' REPOSITORY_PATH ' is not a git command

  - by Judarkness

  I'm using Git with TortoiseGit on Windows XP, and I have a remote bare repository on Windows Vista 64bit version. When I tried to push my local files to remote bare repository, I got the following error message. git.exe push "origin" master:master git: 'C:/Git_Repository/.git' is not a git command. See 'git --help'. fatal: The remote end hung up unexpectedly the arbitrary URL is : username@serverip:C:/Git_Repository/.git The same arbitrary URL worked just fine while doing clone/fetch/pull. Access from a local directory in remote machine to this bare repository has no problem either so I belive there is something wrong with my path. I can push/pull at GitHub correctly but I was using URL provide by GitHub. Does anyone know what's wrong with my configuration? Here is my remote .git/config [core] repositoryformatversion = 0 filemode = false bare = true logallrefupdates = true ignorecase = true hideDotFiles = dotGitOnly Here is my local .git/config [core] repositoryformatversion = 0 filemode = false bare = false logallrefupdates = true symlinks = false ignorecase = true hideDotFiles = dotGitOnly [remote "origin"] fetch = +refs/heads url = username@serverip:C:/Git_Repository/.git [branch "master"] remote = origin merge = refs/heads/master Thanks for the reminding
