• Django website on Apache with wsgi failing

  - by notagain

  I have a website I've built in django that I'm trying to get working on our corporate Apache server (on debian) for our intranet at my workplace. Unfortunately, Apache keeps returning server errors whenever I try to navigate to my site. Although I can navigate to the statics folder. My Apache config and wsgi script look like the following... lbirdf.wsgi import os import sys sys.path.append('/home/lbi/rdfweb/web') sys.path.append('/home/lbi/rdfweb/lbirdf') os.environ['DJANGO_SETTINGS_MODULE'] = 'lbirdf.settings_production' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() Apache config Listen 8080 <VirtualHost *:8080> ServerName server1 WSGIScriptAlias /rdfweb /home/lbi/rdfweb/web/lbirdf/apache/lbirdf.wsgi Alias /statics /home/lbi/rdfweb/web/lbirdf/statics Alias /admin_media /home/lbi/rdfweb/web/lbirdf/admin_media <Directory /home/lbi/rdfweb/web/lbirdf/apache> Order allow,deny Allow from all </Directory> <Directory /home/lbi/rdfweb/web/lbirdf/admin_media> Order allow,deny Allow from all </Directory> </VirtualHost> Any ideas on where I might be going wrong?

• PropertyPlaceholderConfigurer vs Filters -- Spring Beans

  - by John

  Hi there. I've got a question regarding the difference between PropertyPlaceholderConfigurer (org.springframework.beans.factory.config.PropertyPlaceholderConfigurer) and normal filters defined in my pom.xml. I've been looking at examples, and it seems that even though filters are defined and marked to be active by default in the pom.xml they still make use of PropertyPlaceholderConfigurer in Spring's applicationContext.xml. This means that the pom.xml has a reference to a filter-LOCAL.properties while applicationContext.xml has a reference to application.properties and they both contain the same settings. Why is that? Is that how it is supposed to be done? I'm able to run the goal mvn jetty:run without the application.properties present, but if I add settings to the application.properties that differ from the filter-LOCAL.properties they don't seem to override. Here's an example of what I mean: pom.xml <profiles <profile <idLOCAL <activation <activeByDefaulttrue </activation <properties <envLOCAL </properties </profile </profiles applicationContext.xml <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" <property name="locations" <list <valueclasspath:application.properties </list </property <property name="ignoreResourceNotFound" value="true"/ </bean <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" <property name="driverClassName" value="${jdbc.driver}"/ <property name="url" value="${jdbc.url}"/ <property name="username" value="${jdbc.username}"/ <property name="password" value="${jdbc.password}"/ </bean an example of the content of application.properties and filters-LOCAL.properties jdbc.driver=org.postgresql.Driver jdbc.url=jdbc:postgresql://localhost/shoutbox_dev jdbc.username=tester jdbc.password=tester Can I remove the propertyConfigurer from the applicationContext, create a PROD filter and disregard the application.properties file, or will that give me issues when deploying to the production server?

• How to use a getter with a nullable?

  - by Desmond Lost

  I am reading a bunch of queries from a database. I had an issue with the queries not closing, so I added a CommandTimeout. Now, the individual queries read from the config file each time they are run. How would I make the code cache the int from the config file only once using a static nullable and getter. I was thinking of doing something along the lines of: static int? var; get{ var = null; if (var.HasValue) ...(i dont know how to complete the rest) My actual code: private object ExecuteQuery(string dbConnStr, bool fixIt) { object result = false; using (SqlConnection connection = new SqlConnection(dbConnStr)) { connection.Open(); using (SqlCommand sqlCmd = new SqlCommand()) { AddSQLParms(sqlCmd); sqlCmd.CommandTimeout = 30; sqlCmd.CommandText = _cmdText; sqlCmd.Connection = connection; sqlCmd.CommandType = System.Data.CommandType.Text; sqlCmd.ExecuteNonQuery(); } connection.Close(); } return result; }}

• nServiceBus - Not all commands being received by handler

  - by SimonB

  In a test project based of the nServiceBus pub/sub sample, I've replace the bus.publish with bus.send in the server. The server sends 50 messages with a 1sec wait after each 5 (ie 10 burst of 5 messages). The client does not get all the messages. The soln has 3 projects - Server, Client, and common messages. The server and client are hosted via the nServiceBus generic host. Only a single bus is defined. Both client and server are configured to use StructureMap builder and BinarySerialisation. Server Endpoint: public class EndPointConfig : AsA_Publisher, IConfigureThisEndpoint, IWantCustomInitialization { public void Init() { NServiceBus.Configure.With() .StructureMapBuilder() .BinarySerializer(); } } Server Code : for (var nextId = 1; nextId <= 50; nextId++) { Console.WriteLine("Sending {0}", nextId); IDataMsg msg = new DataMsg { Id = nextId, Body = string.Format("Batch Msg #{0}", nextId) }; _bus.SendLocal(msg); Console.WriteLine(" ...sent {0}", nextId); if ((nextId % 5) == 0) Thread.Sleep(1000); } Client Endpoint: public class EndPointConfig : AsA_Client, IConfigureThisEndpoint, IWantCustomInitialization { public void Init() { NServiceBus.Configure.With() .StructureMapBuilder() .BinarySerializer(); } } Client Clode: public class DataMsgHandler : IMessageHandler<IDataMsg> { public void Handle(IDataMsg msg) { Console.WriteLine("DataMsgHandler.Handle({0}, {1}) - ({2})", msg.Id, msg.Body, Thread.CurrentThread.ManagedThreadId); } } Client and Server App.Config: <MsmqTransportConfig InputQueue="nsbt02a" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig DistributorControlAddress="" DistributorDataAddress=""> <MessageEndpointMappings> <add Messages="Test02.Messages" Endpoint="nsbt02a" /> </MessageEndpointMappings> </UnicastBusConfig> All run via VisualStudio 2008. All 50 messages are sent - but after the 1st or 2nd batch. only 1 msg per batch is sent? Any ideas? I'm assuming config or misuse but ....?

• Maven: trying to get my submodule's poms to NOT inherit a plugin in the parent

  - by jobrahms

  My project has a parent pom and several submodule poms. I've put a plugin in the parent that is responsible for building our installer distributables (using install4j). It doesn't make sense to have this plugin run on the submodules, so I've put false in the plugin's config, as seen below. The problem is, when I run mvn clean install install4j:compile it cleans, compiles, and runs the install4j plugin on the parent, but then it tries to run it on the child modules and crashes. Here's the plugin config <plugin> <groupId>com.google.code.maven-install4j</groupId> <artifactId>maven-install4j-plugin</artifactId> <version>0.1.1</version> <inherited>false</inherited> <configuration> <executable>${devenv.install4jc}</executable> <configFile>${basedir}/newinstaller/ehd-demo.install4j</configFile> <releaseId>${project.version}</releaseId> <attach>false</attach> <skipOnMissingExecutable>true</skipOnMissingExecutable> </configuration> </plugin> Am I misunderstanding the purpose of inherited=false? What is the correct way to get this to work? I'm using maven 2.2.0.

• Why is log4j not behaving as expected?

  - by Kieveli

  I have a co-worker who is trying to get log4j to behave as follows: Log to Stdout By default, disable most output Show only messages from java.sql.PrepareStatement at level debug and up He's getting caught up in the 'level' vs 'priority'. Here is his config file: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration SYSTEM "D:/Java/apache-log4j-1.2.15/src/main/resources/org/apache/log4j/xml/log4j.dtd" > <log4j:configuration> <!-- Appenders --> <appender name="stdout" class="org.apache.log4j.ConsoleAppender"> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%5p %d{ISO8601} [%t][%x] %c - %m%n" /> </layout> </appender> <!-- Loggers for ibatus and JDBC database --> <logger name="java.sql.PreparedStatement"> <level value="debug"/> </logger> <!-- The Root Logger --> <root> <level value="error"/> <appender-ref ref="stdout"/> </root> </log4j:configuration> The output from this shows no messages in the log output. How does he need to change his log4j.xml config file to make it behave as he's expecting?

• Using Cucumber With Modular Sinatra Apps

  - by Rob Conery

  I'm building out a medium-sized application using Sinatra and all was well when I had a single app.rb file and I followed Aslak's guidance up on Github: http://wiki.github.com/aslakhellesoy/cucumber/sinatra As the app grew a bit larger and the app.rb file started to bulge, I refactored out a lot of of the bits into "middleware" style modules using Sinatra::Base, mapping things using a rack-up file (config.ru) etc. The app works nicely - but my specs blew up as there was no more app.rb file for webrat to run against (as defined in the link above). I've tried to find examples on how to work this - and I think I'm just not used to the internal guts of Cuke just yet as I can't find a single way to have it cover all the apps. I tried just pointing to "config.ru" instead of app.rb - but that doesn't work. What I ended up doing - which is completely hackish - is to have a separate app.rb file in my support directory, which has all the requires stuff so I can at least test the model stuff. I can also specify routes in there - but that's not at all what I want to do. So - the question is: how can I get Cucumber to properly work with the modular app approach?

• python gui events out of order

  - by dave

  from Tkinter import * from tkMessageBox import * class Gui: def __init__(self, root): self.container = Frame(root) self.container.grid() self.inputText = Text(self.container, width=50, height=8) self.outputText = Text(self.container, width=50, height=8, bg='#E0E0E0', state=DISABLED) self.inputText.grid(row=0, column=0) self.outputText.grid(row=0, column=1) self.inputText.bind("<Key>", self.translate) def translate(self, event): input = self.inputText.get(0.0, END) output = self.outputText.get(0.0, END) self.outputText.config(state=NORMAL) self.outputText.delete(0.0, END) self.outputText.insert(INSERT, input) self.outputText.config(state=DISABLED) showinfo(message="Input: %s characters\nOutput: %s characters" % (len(input), len(input))) root = Tk() #toplevel object app = Gui(root) #call to the class where gui is defined root.mainloop() #enter event loop Working on a gui in tkinter I'm a little confused as to the sequence the event handlers are run. If you run the above code you'll hopefully see... 1) Editing the text widget triggers the event handler but it seems to fire it off without registering the actual change, 2) Even when the text widget is cleared (ie, keep pressing BackSpace) it still seems to have a one character length string, 3) The output widget only receives its update when the NEXT event trigger is fired despite the fact the data came on the previous event. Is this just how bindings work in tkinter or am i missing something here? The behaviour i would like when updating the input widget is: 1) Show the change, 2) Enter event handler, 3) Update output widget, 4) Show message box.

• Web development scheme for staging and production servers using Git Push

  - by ServAce85

  I am using git to manage a dynamic website (PHP + MySQL) and I want to send my files from my localhost to my staging and development servers in the most efficient and hassle-free way. I am currently convinced that the best way for me to approach this problem is to use this git branching model to organize my local git repo. From there, I will use the release branches to push to my staging server for testing. Once I am happy that the release code works on the staging server, I can then merge with my master branch and push that to my production server. Pushing to Staging Server: As noted in many introductory git posts, I could run into problems pushing into a non-bare repo, so, as suggested in this response, I plan to push the release branch to a bare repo on the server and have a post-receive hook that clones the bare repo to a non-bare repo that also acts as the web-hosted directory. Pushing to Production Server: Here's my newest source of confusion... In the response that I cited above, it made me curious as to why @Paul states that it's a completely different story when pushing to a live, development server. I guess I don't see the problem. Would it be safe and hassle-free to follow the same steps as above, but for the master branch? Where are the potential pit-falls? Config Files: With respect to configuration files that are unique to each environment (.htaccess, config.php, etc), it seems simplest to .gitignore each of those files in their respective repos on their respective servers. Can you see anything immediately wrong with this? Better solutions? Accessing Data: Finally, as I initially stated, the site uses MySQL databases to store data. How would you suggest I access that data (for testing purposes) from the staging server and localhost? I realize that I may have asked way too many questions for a single post, but since they're all related to the best way to set up this development scheme, I thought it was necessary.

• How to add deploy.jar to classpath?

  - by dma_k

  I am facing the problem: I need to add ${java.home}/lib/deploy.jar JAR file to classpath in the runtime (dynamically from java). The solution with Thread#setContextClassLoader(ClassLoader) (mentioned here) does not work because of this bug (if somebody can explain what is really a problem – you are welcome). The solution with -Xbootclasspath/a:"%JAVA_HOME%/jre/lib/deploy.jar" does not work well for me, because I want to have "pure executable jar" as a deliverable: no wrapping scripts please (more over %JAVA_HOME% may not be defined in user's environment in Windows for example, plus I need to write a script per platform) The solution with merging deploy.jar file into my deliverable works only if I make a build on Windows platform. Unfortunately, when the deliverable is produced on build server running on Linux, I got Linux-dependant JAR, which does not execute on Windows – it fails with the trace below. I have read How the Java Launcher Finds Classes and Java programming dynamics: Java classes and class loading articles but I've got no extra ideas, how to correctly handle this situation. Any advices or solutions are very welcomed. Trace: java.lang.NoClassDefFoundError: Could not initialize class com.sun.deploy.config.Config at com.sun.deploy.net.proxy.UserDefinedProxyConfig.getBrowserProxyInfo(UserDefinedProxyConfig.java:43) at com.sun.deploy.net.proxy.DynamicProxyManager.reset(DynamicProxyManager.java:235) at com.sun.deploy.net.proxy.DeployProxySelector.reset(DeployProxySelector.java:59) ... java.lang.NullPointerException at com.sun.deploy.net.proxy.DynamicProxyManager.getProxyList(DynamicProxyManager.java:63) at com.sun.deploy.net.proxy.DeployProxySelector.select(DeployProxySelector.java:166)

• Stop CDATA tags from being output-escaped when writing to XML in C#

  - by Smallgods

  We're creating a system outputting some data to an XML schema. Some of the fields in this schema need their formatting preserved, as it will be parsed by the end system into potentially a Word doc layout. To do this we're using <![CDATA[Some formatted text]]> tags inside of the App.Config file, then putting that into an appropriate property field in a xsd.exe generated class from our schema. Ideally the formatting wouldn't be out problem, but unfortunately thats just how the system is going. The App.Config section looks as follows: <header> <![CDATA[Some sample formatted data]]> </header> The data assignment looks as follows: HeaderSection header = ConfigurationManager.GetSection("header") as HeaderSection; report.header = "<[CDATA[" + header.Header + "]]>"; Finally, the Xml output is handled as follows: xs = new XmlSerializer(typeof(report)); fs = new FileStream (reportLocation, FileMode.Create); xs.Serialize(fs, report); fs.Flush(); fs.Close(); This should in theory produce in the final Xml a section that has information with CDATA tags around it. However, the angled brackets are being converted into &lt; and &gt; I've looked at ways of disabling Outout Escaping, but so far can only find references to XSLT sheets. I've also tried @"<[CDATA[" with the strings, but again no luck. Any help would be appreciated!

• how to change ASP.NET Configuration tool connection string

  - by Zviadi

  Hello, how can I change ASP.NET Configuration tool-s connection string name? (Which connection string will ASP.NET Configuration tool will use) I'm learning ASP.NET and everywhere and in book that I'm reading now theres connection string named: LocalSqlServer. I want to use my local sql server database instead of sql express to store Roles, Membership and other data. I have used aspnet_regsql.exe to create needed data structures in my database. after that I changed my web.config to look like: <connectionStrings> <remove name="LocalSqlServer"/> <add name="LocalSqlServer" connectionString="Server=(LOCAL); Database=MyDatabase;Integrated Security=True" providerName="System.Data.SqlClient" /> </connectionStrings> but when I run ASP.NET Configuration tool it says that: "The connection name 'ApplicationServices' was not found in the applications configuration or the connection string is empty." ASP.NET Configuration tool uses connection string named: ApplicationServices not LocalSqlServer. cause of that I have to modify web.config to: <connectionStrings> <add name="ApplicationServices" connectionString="Server=(LOCAL); Database=MyDatabase;Integrated Security=True" providerName="System.Data.SqlClient" /> </connectionStrings> and everything works fine. I wish to know why the hell my web site uses connection string named: ApplicationServices and all books and online documentations uses LocalSqlServer? and how to change it to LocalSqlServer? I have: Windows 7 Sql Server 2008 R2 Visual Studio 2010 Premium Project type is website

• Why I get this error in CXF

  - by Milan

  I want to make dynamic web service invoker in JSF with CXF. But when I load this simple code I get error. The code: JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance(); Client client = dcf.createClient("http://ws.strikeiron.com/IPLookup2?wsdl"); The error: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions! If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml. A typical config looks like this; org.apache.myfaces.webapp.StartupServletContextListener Caused by: java.lang.IllegalStateException - No Factories configured for this Application.

• I just need one dependent module , but don't need its dependencies (Maven)

  - by smallufo

  In my project , there is a spring XML config that utilizes ehcache to cache method returns. xml snippet : http://www.springmodules.org/schema/ehcache http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd <ehcache:config configLocation="classpath:ehcache.xml"/> <ehcache:proxy id="explainRetriever" refId="explainRetrieverImpl"> <ehcache:caching methodName="get*" cacheName="explainCache"/> </ehcache:proxy> but in runtime , server complains it cannot find definitions of http://www.springmodules.org/schema/ehcache , I know I have to add "spring-modules-cache.jar" to WEB-INF/lib directory. But my project is maintained by maven , if I add "spring-modules-cache" to the runtime dependency , it will bring a lot of dependencies to my WAR file , filling my WAR with a lot of unnecessary jars. I just need one declaration in it , not all of its dependencies ... Is there any way to tell maven not to include its dependencies to the project ? Or ... another way , when packaging WAR , just copy another prepared spring-modules-cache.jar to WEB-INF/lib , how to do this ? Thanks !

• Visual Studio crashes when I add a .settings file in a C++ Windows form application

  - by Ant

  I'm trying to add a .settings file in a windows form application by adding a (whatever) file in the project and have it named smthng.settings. Right after it is created, it crashes (if I look into the project's directory the file is there, but it's not "in" the project). Am I doing it wrong or could it be that the problem lies elsewhere? Edit: It seems that it's the settings designer that crashes. Partially Solved:If I add a (whatever).config file, then rename it to .settings and change it's file type to C/C++ Code (don't ask how I figured this out..) then I can add to it settings, but if I do add something that has any connection to the form then automatically a (whatever).config with thew same name spawns (which is identical to the (whatever).setting even if change one of them) and at the stdafx.cpp a #include '(whatever).h' appears, which is a problem, because there is not such a header. (if I erase it or just create a blank (whatever).h it doesn't work. Apparently I have to somehow connect all the data in the (w/e).settings to (w/e).h as well or maybe something else) Anyone had this problem before? Anyone has any ideas?

• Updating section in ConfigParser (or an alternative)

  - by lyrae

  I am making a plugin for another program and so I am trying to make thing as lightweight as possible. What i need to do is be able to update the name of a section in the ConfigParser's config file. [project name] author:john doe email: [email protected] year: 2010 I then have text fields where user can edit project's name, author, email and year. I don't think changing [project name] is possible, so I have thought of two solutions: 1 -Have my config file like this: [0] projectname: foobar author:john doe email: [email protected] year: 2010 that way i can change project's name just like another option. But the problem is, i would need the section # to be auto incremented. And to do this i would have to get every section, sort of, and figure out what the next number should be. The other option would be to delete the entire section and its value, and re-add it with the updated values which would require a little more work as well, such as passing a variable that holds the old section name through functions, etc, but i wouldn't mind if it's faster. Which of the two is best? or is there another way? I am willing to go with the fastest/lightweight solution possible, doesn't matter if it requires more work or not.

• Precompile assets for a rails engine

  - by Peter Ehrlich

  In a standard app, I have this line in my production.rb, which creates endpoints for non-default precompiled assets: config.assets.precompile += %w( mobile.css ) My rails engine is a standard Sinatra app. It has its own assets. When on development, these assets are served fine, presumably the web requests are handled by rails and sprockets. On production I'm getting 404s on the assets, and think I have to manually tell sprockets to provide the files. How can this be done without tightly linking? It isin't evident how to set up env-specific initializers for engines. Is this done? Not only, for example, is config/development.rb within the engine not loaded, but there's no way to get the application class itself without knowing its name, in order to modify configuration. And even if there was, it seems that having any engine able to reconfigure the main app would be very bad idea. So maybe its better to let assets handling be done by sinatra itself? Or another instance of sprockets for the engine? How do other engines handle this?

• Why does Rails screw up timezones when I am editing a resource?

  - by DJTripleThreat

  Steps to produce this: prompt>rails test_app prompt>cd test_app prompt>script/generate scaffold date_test my_date:datetime prompt>rake db:migrate now edit your app/views/date_tests/edit.html.erb: <h1>Editing date_test</h1> <% form_for(@date_test) do |f| %> <%= f.error_messages %> <p> RIGHT!<br/> <%= text_field_tag @date_test, f.object.my_date %> </p> <p> WRONG!<br /> <%= f.text_field :my_date %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> <%= link_to 'Show', @date_test %> | <%= link_to 'Back', date_tests_path %> now edit your config/environment.rb: #add this config.time_zone = 'Central Time (US & Canada)' This recreates the problem I am having in my actual app. The problem with my app is that I'm storing a date in a hidden field and rendering a "user friendly" version. Creating a resource works fine but as soon as I try to edit it the time changes (it adds the difference between my current time zone configuration and UTC). go to http://localhost:3000/date_tests/new and save the time then go to reedit it and you will have two different representations of the date/time one which will save incorrectly and the other that will.

• Structuring the UI code of a single-page EXTjs Web app using Rails?

  - by Daniel Beardsley

  I’m in the process of creating a large single-page web-app using ext-js for the UI components with Rails on the backend. I’ve come to good solutions for transferring data using Whorm gem and Rails support of RESTful Resources. What I haven’t come to a conclusion on is how to structure the UI and business logic aspects of the application. I’ve had a look at a few options, including Netzke but haven’t seen anything that I really think fits my needs. How should a web-application that uses ext-js components, layouts, and controls in the browser and Rails on the server best implement UI component re-use, good organization, and maintainability while maintaining a flexible layout design. Specifically I’m looking for best-practice suggestions for structuring the code that creates and configures UI components (many UI config options will be based on user data) Should EXT classes be extended in static JS for often re-used customizations and then instantiated with various configuration options by generated JS within html partials? Should partials create javascript blocks that instantiate EXT components? Should partials call helpers that return ruby hashes for EXT component config which is then dumped to Json? Something else entirely? There are many options and I'd love to hear from people who've been down this road and found some methodology that worked for them.

• How to make NSIS create a file in an %APPDATA% of another user?

  - by SCO

  I wrote an NSIS installer script for postgresql 9.1. The installer works properly, but after the reboot, the service is not started (right after the install, the database started properly though) I guess this is because the postgres service user has no pgpass.conf file in its %APPDATA%. As far as I understand my install script, the pgpass.conf file is added to the %APPDATA% of the user running the installer (an administrator account in my case). This will not help. I tried the following, to add the pgpass.conf to all users, bt I guess this adds it to a kind of wildcard, not to the %APPDATA% of each user : SetShellVarContext "all" SetOutPath "$APPDATA\postgresql" File config\pgpass.conf SetShellVarContext "current" SetOutPath "$APPDATA\postgresql" File config\pgpass.conf I couldn't find the macro name for c:/Users/postgres in the documentation. This could be a way to achieve it. But with WindowsXP, 7, I wish I need a portable way to address the /Users directory. I wish I could use something like SetShellVarContext "postgres", and then have NSIS write the pgpass.conf file in c:\Users\postgres\AppData\postgresql. Is there a way to do this ? Thnk you !
