  • Netbeans platform projects - problems with wrapped jar files that have dependencies

    - by I82Much
    For starters, this question is not so much about programming in the NetBeans IDE as developing a NetBeans project (e.g. using the NetBeans Platform framework). I am attempting to use the BeanUtils library to introspect my domain models and provide the properties to display in a property sheet. Sample code: public class MyNode extends AbstractNode implements PropertyChangeListener { private static final PropertyUtilsBean bean = new PropertyUtilsBean(); // snip protected Sheet createSheet() { Sheet sheet = Sheet.createDefault(); Sheet.Set set = Sheet.createPropertiesSet(); APIObject obj = getLookup().lookup (APIObject.class); PropertyDescriptor[] descriptors = bean.getPropertyDescriptors(obj); for (PropertyDescriptor d : descriptors) { Method readMethod = d.getReadMethod(); Method writeMethod = d.getWriteMethod(); Class valueType = d.getClass(); Property p = new PropertySupport.Reflection(obj, valueType, readMethod, writeMethod); set.put(p); } sheet.put(set); return sheet; } I have created a wrapper module around commons-beanutils-1.8.3.jar, and added a dependency on the module in my module containing the above code. Everything compiles fine. When I attempt to run the program and open the property sheet view (i.e.. the above code actually gets run), I get the following error: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:319) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:254) at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:259) Caused: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory starting from ModuleCL@64e48e45[org.apache.commons.beanutils] with possible defining loaders [ModuleCL@75da931b[org.netbeans.libs.commons_logging]] and declared parents [] at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:261) at java.lang.ClassLoader.loadClass(ClassLoader.java:254) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:399) Caused: java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at org.apache.commons.beanutils.PropertyUtilsBean.<init>(PropertyUtilsBean.java:132) at org.myorg.myeditor.MyNode.<clinit>(MyNode.java:35) at org.myorg.myeditor.MyEditor.<init>(MyEditor.java:33) at org.myorg.myeditor.OpenEditorAction.actionPerformed(OpenEditorAction.java:13) at org.openide.awt.AlwaysEnabledAction$1.run(AlwaysEnabledAction.java:139) at org.netbeans.modules.openide.util.ActionsBridge.implPerformAction(ActionsBridge.java:83) at org.netbeans.modules.openide.util.ActionsBridge.doPerformAction(ActionsBridge.java:67) at org.openide.awt.AlwaysEnabledAction.actionPerformed(AlwaysEnabledAction.java:142) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2028) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2351) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:387) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:242) at javax.swing.AbstractButton.doClick(AbstractButton.java:389) at com.apple.laf.ScreenMenuItem.actionPerformed(ScreenMenuItem.java:95) at java.awt.MenuItem.processActionEvent(MenuItem.java:627) at java.awt.MenuItem.processEvent(MenuItem.java:586) at java.awt.MenuComponent.dispatchEventImpl(MenuComponent.java:317) at java.awt.MenuComponent.dispatchEvent(MenuComponent.java:305) [catch] at java.awt.EventQueue.dispatchEvent(EventQueue.java:638) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:125) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:296) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:211) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:196) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:188) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122) I understand that beanutils is using the commons-logging component. I have tried adding the commons-logging component in two different ways (creating a wrapper library around the commons-logging library, and putting a dependency on the Commons Logging Integration library). Neither solves the problem. I noticed that the same problem occurs with other wrapped libraries; if they themselves have external dependencies, the ClassNotFoundExceptions propagate like mad, even if I've wrapped the jars of the libraries they require and added them as dependencies to the original wrapped library module. Pictorially: I'm at my wits end here. I noticed similar problems while googling: Is there a known bug on NB Module dependency Same issue I'm facing but when wrapping a different jar NetBeans stance on this - none of the 3 apply to me. None conclusively help me. Thank you, Nick

  • NDepend tool – Why every developer working with Visual Studio.NET must try it!

    - by hajan
    In the past two months, I have had a chance to test the capabilities and features of the amazing NDepend tool designed to help you make your .NET code better, more beautiful and achieve high code quality. In other words, this tool will definitely help you harmonize your code. I mean, you’ve probably heard about Chaos Theory. Experienced developers and architects are already advocates of the programming chaos that happens when working with complex project architecture, the matrix of relationships between objects which simply even if you are the one who have written all that code, you know how hard is to visualize everything what does the code do. When the application get more and more complex, you will start missing a lot of details in your code… NDepend will help you visualize all the details on a clever way that will help you make smart moves to make your code better. The NDepend tool supports many features, such as: Code Query Language – which will help you write custom rules and query your own code! Imagine, you want to find all your methods which have more than 100 lines of code :)! That’s something simple! However, I will dig much deeper in one of my next blogs which I’m going to dedicate to the NDepend’s CQL (Code Query Language) Architecture Visualization – You are an architect and want to visualize your application’s architecture? I’m thinking how many architects will be really surprised from their architectures since NDepend shows your whole architecture showing each piece of it. NDepend will show you how your code is structured. It shows the architecture in graphs, but if you have very complex architecture, you can see it in Dependency Matrix which is more suited to display large architecture Code Metrics – Using NDepend’s panel, you can see the code base according to Code Metrics. You can do some additional filtering, like selecting the top code elements ordered by their current code metric value. You can use the CQL language for this purpose too. Smart Search – NDepend has great searching ability, which is again based on the CQL (Code Query Language). However, you have some options to search using dropdown lists and text boxes and it will generate the appropriate CQL code on fly. Moreover, you can modify the CQL code if you want it to fit some more advanced searching tasks. Compare Builds and Code Difference – NDepend will also help you compare previous versions of your code with the current one at one of the most clever ways I’ve seen till now. Create Custom Rules – using CQL you can create custom rules and let NDepend warn you on each build if you break a rule Reporting – NDepend can automatically generate reports with detailed stats, graph representation, dependency matrixes and some additional advanced reporting features that will simply explain you everything related to your application’s code, architecture and what you’ve done. And that’s not all. As I’ve seen, there are many other features that NDepend supports. I will dig more in the upcoming days and will blog more about it. The team who built the NDepend have also created good documentation, which you can find on the NDepend website. On their website, you can also find some good videos that will help you get started quite fast. It’s easy to install and what is very important it is fully integrated with Visual Studio. To get you started, you can watch the following Getting Started Online Demo and Tutorial with explanations and screenshots. If you are interested to know more about how to use the features of this tool, either visit their website or wait for my next blogs where I will show some real examples of using the tool and how it helps make your code better. And the last thing for this blog, I would like to copy one sentence from the NDepend’s home page which says: ‘Hence the software design becomes concrete, code reviews are effective, large refactoring are easy and evolution is mastered.’ Website: www.ndepend.com Getting Started: http://www.ndepend.com/GettingStarted.aspx Features: http://www.ndepend.com/Features.aspx Download: http://www.ndepend.com/NDependDownload.aspx Hope you like it! Please do let me know your feedback by providing comments to my blog post. Kind Regards, Hajan

    - by Aamir Hasan
     Microsoft SQL Server 2008 is a new version released in the first half of 2008 introducing new properties and capabilities to SQL Server product family. All these new and enhanced capabilities can be defined as the classic words like secure, reliable, scalable and manageable. SQL Server 2008 is secure. It is reliable. SQL2008 is scalable and is more manageable when compared to previous releases. Now we will have a look at the features that are making MS SQL Server 2008 more secure, more reliable, more scalable, etc. in details.Microsoft SQL Server 2008 provides T-SQL enhancements that improve performance and reliability.

  • A debugging experience with "highly compatible" ASP.NET 4.5

    - by Jeff
    I have to admit that I will pretty much upgrade software for no reason other than being on the latest version. I won't do it if it's super expensive (Adobe gets money from me about once every three or four years at best), but particularly with frameworks and stuff generally available as part of my MSDN subscription, I'll be bleeding edge. CoasterBuzz was running on the MVC 4 framework pretty much as soon as they did a "go live" license for it. I didn't really jump in head-first with Windows 8 and Visual Studio 2012, in part because I just wasn't interested in doing the reinstalls for each new version. Turns out there weren't that many revisions anyway. But when the final versions were released a week and a half ago, I jumped in. I saw on one of the Microsoft sites that .Net 4.5 was a "highly compatible in-place update" to the framework. Good enough for me. I was obviously running it by default in Windows 8, and installed it on my production server. I suppose it's "highly compatible," except when it isn't. Three of my sites are running with various flavors of the MVC version of POP Forums. All of them stopped working under ASP.NET 4.5. It was not immediately obvious what the problem might be beyond an exception indicating that there were no repository classes registered with Ninject, which I use for dependency injection in the forums. This was made all the more weird by the fact that it ran fine locally in the dev Web host. My first instinct was to spin up a Windows Server VM on my local box and put the remote debugger on it. (Side note: running multiple VM's on a Retina MacBook Pro with 16 gigs of RAM is pretty much the most awesome thing ever. I can't believe this computer is for real, and not a 50-pound tower under my desk.) What might have been going on in IIS that doesn't happen in Visual Studio? In the debugging process, I realized that I might be looking in the wrong place. POP Forums creates a Ninject container using a method called from a PreApplicationStartMethod attribute, and at that time registers a module (what Ninject uses to map interfaces to implementations) that maps all of the core dependencies. It also creates an instance of an HttpModule that originally hosted the "services" (search indexing, mailer, etc.), but now just records errors. That's all well and good, but the actual repository mapping, where data is actually read or persisted, happens in Application_Start() in global.asax. The idea there is that you can swap out the SqlSingleWebServer repos for something tuned for multiple servers, Oracle or something else. Of course, if I used something like StructureMap, which does convention-based mapping for dependency injection (a class implementing ISettingsRepository called SettingsRepository is automagically mapped), I wouldn't have to worry about it. In any case, the HttpModule, being instantiated before Application_Start() gets to run, would throw because there was no repo mapped where it could get settings from the database. This makes total sense. The fix is sort of a hack, where I don't setup the innards of the HttpModule until a call to its BeginRequest is made. I say it's a hack, because its primary function, logging exceptions, won't work until the app has warmed up. Still, this brings up an interesting question about the race condition, and what changed in 4.5 when it's running in IIS. In ASP.NET 4, it would appear that the code called via the PreApplicationStartMethod was either failing silently, and running again later, or it was getting to that code after Application_Start was called. In any case, weird thing. The real pain point I'm experiencing now is a bug in MVC 4 that is extremely serious because it renders the mobile/alternate view functionality very much broken.

  • Adventures in MVVM &ndash; ViewModel Location and Creation

    - by Brian Genisio's House Of Bilz
    More Adventures in MVVM In this post, I am going to explore how I prefer to attach ViewModels to my Views.  I have published the code to my ViewModelSupport project on CodePlex in case you'd like to see how it works along with some examples.  Some History My approach to View-First ViewModel creation has evolved over time.  I have constructed ViewModels in code-behind.  I have instantiated ViewModels in the resources sectoin of the view. I have used Prism to resolve ViewModels via Dependency Injection. I have created attached properties that use Dependency Injection containers underneath.  Of all these approaches, I continue to find issues either in composability, blendability or maintainability.  Laurent Bugnion came up with a pretty good approach in MVVM Light Toolkit with his ViewModelLocator, but as John Papa points out, it has maintenance issues.  John paired up with Glen Block to make the ViewModelLocator more generic by using MEF to compose ViewModels.  It is a great approach, but I don’t like baking in specific resolution technologies into the ViewModelSupport project. I bring these people up, not to name drop, but to give them credit for the place I finally landed in my journey to resolve ViewModels.  I have come up with my own version of the ViewModelLocator that is both generic and container agnostic.  The solution is blendable, configurable and simple to use.  Use any resolution mechanism you want: MEF, Unity, Ninject, Activator.Create, Lookup Tables, new, whatever. How to use the locator 1. Create a class to contain your resolution configuration: public class YourViewModelResolver: IViewModelResolver { private YourFavoriteContainer container = new YourFavoriteContainer(); public YourViewModelResolver() { // Configure your container } public object Resolve(string viewModelName) { return container.Resolve(viewModelName); } } Examples of doing this are on CodePlex for MEF, Unity and Activator.CreateInstance. 2. Create your ViewModelLocator with your custom resolver in App.xaml: <VMS:ViewModelLocator x:Key="ViewModelLocator"> <VMS:ViewModelLocator.Resolver> <local:YourViewModelResolver /> </VMS:ViewModelLocator.Resolver> </VMS:ViewModelLocator> 3. Hook up your data context whenever you want a ViewModel (WPF): <Border DataContext="{Binding YourViewModelName, Source={StaticResource ViewModelLocator}}"> This example uses dynamic properties on the ViewModelLocator and passes the name to your resolver to figure out how to compose it. 4. What about Silverlight? Good question.  You can't bind to dynamic properties in Silverlight 4 (crossing my fingers for Silverlight 5), but you CAN use string indexing: <Border DataContext="{Binding [YourViewModelName], Source={StaticResource ViewModelLocator}}"> But, as John Papa points out in his article, there is a silly bug in Silverlight 4 (as of this writing) that will call into the indexer 6 times when it binds.  While this is little more than a nuisance when getting most properties, it can be much more of an issue when you are resolving ViewModels six times.  If this gets in your way, the solution (as pointed out by John), is to use an IndexConverter (instantiated in App.xaml and also included in the project): <Border DataContext="{Binding Source={StaticResource ViewModelLocator}, Converter={StaticResource IndexConverter}, ConverterParameter=YourViewModelName}"> It is a bit uglier than the WPF version (this method will also work in WPF if you prefer), but it is still not all that bad.  Conclusion This approach works really well (I suppose I am a bit biased).  It allows for composability from any mechanisim you choose.  It is blendable (consider serving up different objects in Design Mode if you wish... or different constructors… whatever makes sense to you).  It works in Cider.  It is configurable.  It is flexible.  It is the best way I have found to manage View-First ViewModel hookups.  Thanks to the guys mentioned in this article for getting me to something I love using.  Enjoy.

  • MvcExtensions - ActionFilter

    - by kazimanzurrashid
    One of the thing that people often complains is dependency injection in Action Filters. Since the standard way of applying action filters is to either decorate the Controller or the Action methods, there is no way you can inject dependencies in the action filter constructors. There are quite a few posts on this subject, which shows the property injection with a custom action invoker, but all of them suffers from the same small bug (you will find the BuildUp is called more than once if the filter implements multiple interface e.g. both IActionFilter and IResultFilter). The MvcExtensions supports both property injection as well as fluent filter configuration api. There are a number of benefits of this fluent filter configuration api over the regular attribute based filter decoration. You can pass your dependencies in the constructor rather than property. Lets say, you want to create an action filter which will update the User Last Activity Date, you can create a filter like the following: public class UpdateUserLastActivityAttribute : FilterAttribute, IResultFilter { public UpdateUserLastActivityAttribute(IUserService userService) { Check.Argument.IsNotNull(userService, "userService"); UserService = userService; } public IUserService UserService { get; private set; } public void OnResultExecuting(ResultExecutingContext filterContext) { // Do nothing, just sleep. } public void OnResultExecuted(ResultExecutedContext filterContext) { Check.Argument.IsNotNull(filterContext, "filterContext"); string userName = filterContext.HttpContext.User.Identity.IsAuthenticated ? filterContext.HttpContext.User.Identity.Name : null; if (!string.IsNullOrEmpty(userName)) { UserService.UpdateLastActivity(userName); } } } As you can see, it is nothing different than a regular filter except that we are passing the dependency in the constructor. Next, we have to configure this filter for which Controller/Action methods will execute: public class ConfigureFilters : ConfigureFiltersBase { protected override void Configure(IFilterRegistry registry) { registry.Register<HomeController, UpdateUserLastActivityAttribute>(); } } You can register more than one filter for the same Controller/Action Methods: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(); You can register the filters for a specific Action method instead of the whole controller: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(c => c.Index()); You can even set various properties of the filter: registry.Register<ControlPanelController, CustomAuthorizeAttribute>( attribute => { attribute.AllowedRole = Role.Administrator; }); The Fluent Filter registration also reduces the number of base controllers in your application. It is very common that we create a base controller and decorate it with action filters and then we create concrete controller(s) so that the base controllers action filters are also executed in the concrete controller. You can do the  same with a single line statement with the fluent filter registration: Registering the Filters for All Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type))); Registering Filters for selected Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type) && (type.Name.StartsWith("Home") || type.Name.StartsWith("Post")))); You can also use the built-in filters in the fluent registration, for example: registry.Register<HomeController, OutputCacheAttribute>(attribute => { attribute.Duration = 60; }); With the fluent filter configuration you can even apply filters to controllers that source code is not available to you (may be the controller is a part of a third part component). That’s it for today, in the next post we will discuss about the Model binding support in MvcExtensions. So stay tuned.

  • Implementing a modern web application with Web API on top of old services

    - by Gaui
    My company has many WCF services which may or may not be replaced in the near future. The old web application is written in WebForms and communicates straight with these services via SOAP and returns DataTables. Now I am designing a new modern web application in a modern style, an AngularJS client which communicates with an ASP.NET Web API via JSON. The Web API then communicates with the WCF services via SOAP. In the future I want to let the Web API handle all requests and go straight to the database, but because the business logic implemented in the WCF services is complicated it's going to take some time to rewrite and replace it. Now to the problem: I'm trying to make it easy in the near future to replace the WCF services with some other data storage, e.g. another endpoint, database or whatever. I also want to make it easy to unit test the business logic. That's why I have structured the Web API with a repository layer and a service layer. The repository layer has a straight communication with the data storage (WCF service, database, or whatever) and the service layer then uses the repository (Dependency Injection) to get the data. It doesn't care where it gets the data from. Later on I can be in control and structure the data returned from the data storage (DataTable to POCO) and be able to test the logic in the service layer with some mock repository (using Dependency Injection). Below is some code to explain where I'm going with this. But my question is, does this all make sense? Am I making this overly complicated and could this be simplified in any way possible? Does this simplicity make this too complicated to maintain? My main goal is to make it as easy as possible to switch to another data storage later on, e.g. an ORM and be able to test the logic in the service layer. And because the majority of the business logic is implemented in these WCF services (and they return DataTables), I want to be in control of the data and the structure returned to the client. Any advice is greatly appreciated. Update 20/08/14 I created a repository factory, so services would all share repositories. Now it's easy to mock a repository, add it to the factory and create a provider using that factory. Any advice is much appreciated. I want to know if I'm making things more complicated than they should be. So it looks like this: 1. Repository Factory public class RepositoryFactory { private Dictionary<Type, IServiceRepository> repositories; public RepositoryFactory() { this.repositories = new Dictionary<Type, IServiceRepository>(); } public void AddRepository<T>(IServiceRepository repo) where T : class { if (this.repositories.ContainsKey(typeof(T))) { this.repositories.Remove(typeof(T)); } this.repositories.Add(typeof(T), repo); } public dynamic GetRepository<T>() { if (this.repositories.ContainsKey(typeof(T))) { return this.repositories[typeof(T)]; } throw new RepositoryNotFoundException("No repository found for " + typeof(T).Name); } } I'm not very fond of dynamic but I don't know how to retrieve that repository otherwise. 2. Repository and service // Service repository interface // All repository interfaces extend this public interface IServiceRepository { } // Invoice repository interface // Makes it easy to mock the repository later on public interface IInvoiceServiceRepository : IServiceRepository { List<Invoice> GetInvoices(); } // Invoice repository // Connects to some data storage to retrieve invoices public class InvoiceServiceRepository : IInvoiceServiceRepository { public List<Invoice> GetInvoices() { // Get the invoices from somewhere // This could be a WCF, a database, or whatever using(InvoiceServiceClient proxy = new InvoiceServiceClient()) { return proxy.GetInvoices(); } } } // Invoice service // Service that handles talking to a real or a mock repository public class InvoiceService { // Repository factory RepositoryFactory repoFactory; // Default constructor // Default connects to the real repository public InvoiceService(RepositoryFactory repo) { repoFactory = repo; } // Service function that gets all invoices from some repository (mock or real) public List<Invoice> GetInvoices() { // Query the repository return repoFactory.GetRepository<IInvoiceServiceRepository>().GetInvoices(); } }

So the ExampleTest.java has a todo list at its begining: /* TODO to make this test work:  - add test dependency on Java Hints Test API (and JUnit 4)  - to ensure that the newest Java language features supported by the IDE are available,   regardless of which JDK you build the module with:  -- for Ant-based modules, add "requires.nb.javac=true" into nbproject/project.properties  -- for Maven-based modules, use dependency:copy in validate phase to create   target/endorsed/org-netbeans-libs-javacapi-*.jar and add to endorseddirs   in maven-compiler-plugin configuration  */Warning: if this is a project for which tests never existed before, you may need to close&reopen the project, so that "Unit Test Libraries" node appears - a bug in apisupport projects, as far as I can tell.  Thanks to Jan Lahoda for the above rough guide.

Master Data Management: A Foundation for Big Data Analysis | Manouj Tahiliani "Businesses that have embraced MDM to get a single, enriched and unified view of Master data by resolving semantic discrepancies and augmenting the explicit master data information from within the enterprise with implicit data from outside the enterprise like social profiles will have a leg up in embracing Big Data solutions. This is especially true for large and medium-sized businesses in industries like Retail, Communications, Financial Services, etc that would find it very challenging to get comprehensive analytical coverage and derive long-term success without resolving the limitations of the heterogeneous topology that leads to disparate, fragmented and incomplete master data." — Manouj Tahiliani Architect Day: Boston - Agenda Update Here's the latest updated information on the session schedule and content for Oracle Technology Network Architect Day in Boston, MA on September 12, 2012.

Integrating Coherence & Java EE 6 Applications using ActiveCache | Ricardo Ferreira The seamless integration between Oracle Coherence and Oracle WebLogic Server "provides a comprehensive environment to develop applications without the complexity of extra Java code to manage cache as a dependency," explains Ricardo Ferreira, "since Oracle provides a DI (Dependency Injection) mechanism for Coherence, the same DI mechanism available in standard Java EE applications. This feature is called ActiveCache." Ricardo shows you how to configure ActiveCache in WebLogic and your Java EE application. Cloud Infrastructure has a new standard from the DMTF "Unlike a de facto standard where typically one vendor has change control over the interface, and everyone else has to reverse engineer the inner workings of it, [Cloud Infrastructure Management Interface (CIMI)] is a de jure standard that is under change control of a standards body. One reason the standard took two years to create is that we factored in use cases, requirements and contributed APIs from multiple vendors. These vendors have products shipping today and as a result CIMI has a strong foundation in real world experience."

  • How to remove synaptic without installing all the unwanted packages?

    - by Jay
    I am trying to uninstall synaptic. I prefer using apt-get and other command line tools to manage my packages. So I do not need synaptic and the software manager. I'm trying to remove both of them using apt-get. Its a new box. Recently installed Linux Mint mate 15. After installation, the only thing I did was, sudo apt-get update and sudo apt-get dist-upgrade After that, I did this command for removing synaptic, sudo apt-get remove --purge synaptic But this gives me a very weird output, Reading package lists...

  • Package management system corrupted. Cannot install or remove packages. U12.04LTS

    - by user271490
    Having read other posts, I believe that this may be less about samba than about update system. Below is the log file of the failed installation of Samba. I have been trying without success to install/outstall samba so that I could install anything else ... I cannot either install or remove samba using either update-manager or apt-get (nor indeed Software Centre). One of the errors that I have had to correct is the presence after "removal" (failed) of /usr/share/system-config-samba directory which finally allowed itself to be deleted. That, however was then ... I have U12.04LTS. running on release 63 because I allowed the upgrade to 64 this morning which fell over - no output to monitor - obviously even less support for my graphic chip than I am suffering already (see other posts in this forum). According to my interpretation of the dpkg returned errors there may be some problem with the package files, but if this is the case then it is on servers 'main', 'nantes uni fr' and 'best fr' at the very least if not everywhere. The suggestions offered at Package operation failed and elsewhere have not worked for me. This linked post suggests that a similar error is present in other packages, or that the error is in the 'update system' I have tried ... sudo apt-get remove samba ... autoremove ... install samba ... clean ... update -f all of the above In update-manager I have tried the "reload packages list" which fails to terminate because of the error. I have tried to install and remove samba from the software centre ... :( I am at a loss ... I need help, please! Firstly to recover my apt-get/update-manager/Software Centre so that I can at least carry on with my continuing installation - up to communicating with home network hence need for samba - which brings me to my second requirement ... samba. PS is the issue about "MaxReports" associated or apart? UPDATE! Being heartily sick of restarting FF every 5 seconds I thought I'd try again with Chromium ... and got the same errors from dpkg about corrupt compressed package - coincidence? Of course this was no longer in clipboard when I got here because apport has just errored ... AAARRRGGGH!!! Why does every error clear the clipboard?

  • Converting .docx to pdf (or .doc to pdf, or .doc to odt, etc.) with libreoffice on a webserver on the fly using php

    - by robertphyatt
    Ok, so I needed to convert .docx files to .pdf files on the fly, but none of the free php libraries that were available let me do it on my server (a webservice was not good enough). Basically either I needed to pay for a library (and have it maybe suck) or just deal with the free ones that didn't convert the formatting well enough. Not good enough! I found that LibreOffice (OpenOffice's successor) allows command line conversion using the LibreOffice conversion engine (which DID preserve the formatting like I wanted and generally worked great). I loaded the latest version of Ubuntu (http://www.ubuntu.com/download/ubuntu/download) onto my Virtual Box (https://www.virtualbox.org/wiki/Downloads) on my computer and found that I was able to easily convert files using the commandline like this: libreoffice --headless -convert-to pdf fileToConvert.docx -outdir output/path/for/pdf I thought: sweet...but I don't have admin rights on my host's web server. I tried to use a "portable" version of LibreOffice that I obtained from http://portablelinuxapps.org/ but I was unable to get it to work on my host's webserver, because my host's webserver didn't have all the dependencies (Dependency Hell! http://en.wikipedia.org/wiki/Dependency_hell) I was at a loss of how to make it work, until I ran across a cool project made by a Ph.D. student (Philip J. Guo) at Stanford called CDE: http://www.stanford.edu/~pgbovine/cde.html I will let you look at his explanations of how it works (I followed what he did in http://www.youtube.com/watch?feature=player_embedded&v=6XdwHo1BWwY, starting at about 32:00 as well as the directions on his site), but in short, it allows one to avoid dependency hell by copying all the files used when you run certain commands, recreating the linux environment where the command worked. I was able to use this to run LibreOffice without having to resort to someone's portable version of it, and it worked just like it did when I did it on Ubuntu with the command above, with a tweak: I needed to run the wrapper of LibreOffice the CDE generated. So, below is my PHP code that calls it. In this code snippet, the filename to be copied is passed in as $_POST["filename"]. I copy the file to the same spot where I originally converted the file, convert it, copy it back and then delete all the files (so that it doesn't start growing exponentially). I did it this way because I wasn't able to make it work otherwise on the webserver. If there is a linux + webserver ninja out there that can figure out how to make it work without doing this, I would be interested to know what you did. Please post a comment or something if you did that. <?php //first copy the file to the magic place where we can convert it to a pdf on the fly copy($time.$_POST["filename"], "../LibreOffice/cde-package/cde-root/home/robert/Desktop/".$_POST["filename"]); //change to that directory chdir('../LibreOffice/cde-package/cde-root/home/robert'); //the magic command that does the conversion $myCommand = "./libreoffice.cde --headless -convert-to pdf Desktop/".$_POST["filename"]." -outdir Desktop/"; exec ($myCommand); //copy the file back copy("Desktop/".str_replace(".docx", ".pdf", $_POST["filename"]), "../../../../../documents/".str_replace(".docx", ".pdf", $_POST["filename"])); //delete all the files out of the magic place where we can convert it to a pdf on the fly $files1 = scandir('Desktop'); //my files that I generated all happened to start with a number. $pattern = '/^[0-9]/'; foreach ($files1 as $value) { preg_match($pattern, $value, $matches); if(count($matches) ?> 0) { unlink("Desktop/".$value); } } //changing the header to the location of the file makes it work well on androids header( 'Location: '.str_replace(".docx", ".pdf", $_POST["filename"]) ); ?> And here is the tar.gz file I generated I generated with CDE. To duplicate what I did exactly, put the tar.gz file in a folder somewhere. I will call that folder the "root". Make a new folder called "documents" in the "root" folder. Unpack the tar.gz and run the php script above from the "documents" folder. Success! I made a truly portable version of LibreOffice that can convert files on the fly on a webserver using 100% free, open source software!

  • broken upgrade from 10.04 to 12.04 on a VPS - recoverable?

    - by HorusKol
    I have a VPS hosted 1500 km away. It originally came with 9.10 - and this morning I decided that I really should get to an LTS release, and figured I'd jump to 12.04. Researching, I discovered that there is no direct path between 9.10 and 12.04, but that I could upgrade via 10.04. After backing up my data, I dove in. The upgrade to 10.04 was successful, and I proceeded to upgrade to 12.04. Things started to go wrong. First, I got an error with GLIBC - I retried and got the same error. That's when I stopped the upgrade. I then tried another round of apt-get update && apt-get upgrade and got a list of "unmet dependencies": apt: Depends: ubuntu-keyring but it is not going to be installed Depends: libc6 (>= 2.15) but 2.11.1-0ubuntu7.11 is to be installed Depends: libstdc++6 (>= 4.6) but 4.4.3-4ubuntu5.1 is to be installed PreDepends: dpkg (>= 1.15.7.2) but 1.15.5.6ubuntu4.6 is to be installed apt-utils: Depends: libapt-pkg-libc6.10-6-4.8 libapt-inst1.4: Depends: libc6 (>= 2.14) but 2.11.1-0ubuntu7.11 is to be installed libapt-pkg4.12: Depends: libc6 (>= 2.15) but 2.11.1-0ubuntu7.11 is to be installed Depends: libstdc++6 (>= 4.6) but 4.4.3-4ubuntu5.1 is to be installed libc6: Depends: libc-bin (= 2.11.1-0ubuntu7.11) but 2.15-0ubuntu10.2 is to be installed libept0: Depends: libapt-pkg-libc6.10-6-4.8 libnih-dbus1: Depends: libnih1 (= 1.0.3-4ubuntu9) but 1.0.1-1 is to be installed I tried to see if I could do something about these - using apt-get -f install. This told me that I would need to upgrade my kernel. I found instructions on how to do this, but when I ran apt-get to install the new linux headers, I got the same dependency errors. I found another answer here where someone else had had an interruption in their upgrade - and tried the solution that worked for them: sudo apt-get -f dist-upgrade This resulted in the error: E: Could not perform immediate configuration on 'python2.7-minimal'.Please see man 5 apt.conf under APT::Immediate-Configure for details. (2) I tried to resolve this by: apt-get install -o APT::Immediate-Configure=false -f apt python-minimal But this simply ended up with this last list of dependency errors: apt: Depends: ubuntu-keyring but it is not going to be installed Depends: libc6 (>= 2.15) but 2.11.1-0ubuntu7.11 is to be installed Depends: libstdc++6 (>= 4.6) but 4.4.3-4ubuntu5.1 is to be installed PreDepends: dpkg (>= 1.15.7.2) but 1.15.5.6ubuntu4.6 is to be installed apt-utils: Depends: libapt-pkg-libc6.10-6-4.8 libapt-inst1.4: Depends: libc6 (>= 2.14) but 2.11.1-0ubuntu7.11 is to be installed libapt-pkg4.12: Depends: libc6 (>= 2.15) but 2.11.1-0ubuntu7.11 is to be installed Depends: libstdc++6 (>= 4.6) but 4.4.3-4ubuntu5.1 is to be installed libc6: Depends: libc-bin (= 2.11.1-0ubuntu7.11) but 2.15-0ubuntu10.2 is to be installed libept0: Depends: libapt-pkg-libc6.10-6-4.8 libnih-dbus1: Depends: libnih1 (= 1.0.3-4ubuntu9) but 1.0.1-1 is to be installed python: Depends: python-minimal (= 2.6.5-0ubuntu1) but 2.7.3-0ubuntu2 is to be installed python-apt: Depends: libapt-pkg-libc6.10-6-4.8 python-minimal: Depends: python2.7-minimal (>= 2.7.3) but it is not going to be installed Breaks: python-support (< 1.0.10ubuntu2) but 1.0.4ubuntu1 is to be installed synaptic: Depends: libapt-pkg-libc6.10-6-4.8 Any ideas on how to dig out of this hole?

  • Patterns for a tree of persistent data with multiple storage options?

    - by Robin Winslow
    I have a real-world problem which I'll try to abstract into an illustrative example. So imagine I have data objects in a tree, where parent objects can access children, and children can access parents: // Interfaces interface IParent<TChild> { List<TChild> Children; } interface IChild<TParent> { TParent Parent; } // Classes class Top : IParent<Middle> {} class Middle : IParent<Bottom>, IChild<Top> {} class Bottom : IChild<Middle> {} // Usage var top = new Top(); var middles = top.Children; // List<Middle> foreach (var middle in middles) { var bottoms = middle.Children; // List<Bottom> foreach (var bottom in bottoms) { var middle = bottom.Parent; // Access the parent var top = middle.Parent; // Access the grandparent } } All three data objects have properties that are persisted in two data stores (e.g. a database and a web service), and they need to reflect and synchronise with the stores. Some objects only request from the web service, some only write to it. Data Mapper My favourite pattern for data access is Data Mapper, because it completely separates the data objects themselves from the communication with the data store: class TopMapper { public Top FetchById(int id) { var top = new Top(DataStore.TopDataById(id)); top.Children = MiddleMapper.FetchForTop(Top); return Top; } } class MiddleMapper { public Middle FetchById(int id) { var middle = new Middle(DataStore.MiddleDataById(id)); middle.Parent = TopMapper.FetchForMiddle(middle); middle.Children = BottomMapper.FetchForMiddle(bottom); return middle; } } This way I can have one mapper per data store, and build the object from the mapper I want, and then save it back using the mapper I want. There is a circular reference here, but I guess that's not a problem because most languages can just store memory references to the objects, so there won't actually be infinite data. The problem with this is that every time I want to construct a new Top, Middle or Bottom, it needs to build the entire object tree within that object's Parent or Children property, with all the data store requests and memory usage that that entails. And in real life my tree is much bigger than the one represented here, so that's a problem. Requests in the object In this the objects request their Parents and Children themselves: class Middle { private List<Bottom> _children = null; // cache public List<Bottom> Children { get { _children = _children ?? BottomMapper.FetchForMiddle(this); return _children; } set { BottomMapper.UpdateForMiddle(this, value); _children = value; } } } I think this is an example of the repository pattern. Is that correct? This solution seems neat - the data only gets requested from the data store when you need it, and thereafter it's stored in the object if you want to request it again, avoiding a further request. However, I have two different data sources. There's a database, but there's also a web service, and I need to be able to create an object from the web service and save it back to the database and then request it again from the database and update the web service. This also makes me uneasy because the data objects themselves are no longer ignorant of the data source. We've introduced a new dependency, not to mention a circular dependency, making it harder to test. And the objects now mask their communication with the database. Other solutions Are there any other solutions which could take care of the multiple stores problem but also mean that I don't need to build / request all the data every time?

  • Windows 7 UAC manifest file for some VB6 application

    - by Daniel
    Hi, all, I have an old VB6 application which should run on Windows 7 (with UAV set to the default level, 3 of 4 IMHO). It has the functionality to update itself, and Windows 7 is now complaining that it would modify the computer (At least windows 7 is right here). I was able to run it in Vista with some kind of manifest file, but this does not seem to work anymore (which is the intended behaviour if I think of it). The manifest file is this: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.1.0.24" processorArchitecture="X86" name="IKOfficeAppStarter" type="win32"/> <description>IKOffice Starter</description> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="X86" publicKeyToken="6595b64144ccf1df" language="*"/> </dependentAssembly> </dependency> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> <security> <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="true"/> </requestedPrivileges> </security> </trustInfo> </assembly> The manifest can be found near the exe "IKOffice Starter.exe" and is called "IKOffice Starter.exe.manifest", which should be okey. Currently the Shield Icon has gone from my .exe, but when try to start the software, i get the message "Der angeforderte Vorgang erfordert höhere Rechte", or translated to english "the requested operation requires elevation". What can I do to stop windows to bug me anymore, so I can install this application on our clients computers. Hey, I already told Windows to run it as Invoker, so why is it still complaining?

  • PreferenceActivity and theme not applying

    - by janfsd
    Hi all I have set the theme in the manifest file like this: android:theme="@android:style/Theme.Light" But I have a problem in the Preferences Activity, in the main preferences the theme shows ok, but if I get to a sub preference, the theme gets messy, it is not white as it should, it is all dark, and the font is black so you can't see much, and when I start clicking on any items they will get sometimes white as they should but revert to black soon after. This is only happens on 2.1, in both the real device and emulator. Tested on the emulator running 1.6 and it was working correctly. Here is part of the code of the preferences xml file: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceScreen android:title="@string/account"> <CheckBoxPreference android:key="enable_account" android:title="@string/account_use" android:summary="@string/account_summ" /> <EditTextPreference android:key="username" android:title="@string/login" android:dependency="enable_account" android:summary="@string/login_summ" /> <EditTextPreference android:key="password" android:title="@string/password" android:dependency="enable_account" android:summary="@string/password_summ" android:password="true" /> </PreferenceScreen> And here is a screenshot: Any workarounds?

  • sudo port install arm-elf-gcc3 fails with "No defined site for tag: gcc…"

    - by Scott Bayes
    Am trying to get the ARM plugin for Eclipse (http://sourceforge.net/projects/gnuarmeclipse/) going on iMac i7, OS 10.6.3, Xcode 3.2.2 (don't want to upgrade during my project). The plugin needs (IIRC) arm-elf-gcc3, which needs darwinports for "easy" install. Of course, probably due to leftovers when I moved from old MacBook to iMac, Darwin ports 1.8.2 wouldn't install till I built 1.7.1 from source and installed it. darwinports 1.8.1 appears to have been properly installed, but sudo port install arm-elf-gcc3 led to 5-10 minutes of dependencies installs, then the following, produced with port -d (starting from last dependency completion for brevity): DEBUG: Found Dependency: receipt exists for gettext DEBUG: Executing org.macports.main (arm-elf-gcc3) --- Fetching arm-elf-gcc3 DEBUG: Executing org.macports.fetch (arm-elf-gcc3) --- gcc-3.4.6.tar.bz2 doesn't seem to exist in /opt/local/var/macports/distfiles/gcc Error: No defined site for tag: gcc, using master_sites Error: Target org.macports.fetch returned: can't read "host": no such variable DEBUG: Backtrace: can't read "host": no such variable while executing "info exists seen($host)" (procedure "sortsites" line 25) invoked from within "sortsites fetch_urls" (procedure "portfetch::fetchfiles" line 49) invoked from within "portfetch::fetchfiles" (procedure "portfetch::fetch_main" line 16) invoked from within "$procedure $targetname" Warning: the following items did not execute (for arm-elf-gcc3): org.macports.activate org.macports.fetch org.macports.extract org.macports.checksum org.macports.patch org.macports.configure org.macports.build org.macports.destroot org.macports.install Error: Status 1 encountered during processing. (sorry if that's a mess, neither blockquote nor code sample tags seem to properly display cut/pasted text from Terminal.app in preview window). Can anyone advise me on how to get around this (or how to build/install arm-elf-gcc3 from source if necessary)? None of the darwinports FAQs or forums mentioned arm-elf-gcc3 anywhere that I saw.

  • jstl taglib not found, where have I gone wrong?

    - by James.Elsey
    I'm trying to add Google Maps onto my JSPs by using the googlemaps jstl taglib. I've added this into my maven pom <dependency> <groupId>com.lamatek</groupId> <artifactId>googlemaps</artifactId> <version>0.98c</version> <scope>provided<>/scope </dependency> This then included the googlemaps-0.98c library under my project libraries in NetBeans, I right clicked and selected Manually install artifact and located the googlemaps.jar file I had downloaded. I've then added this into my taglibs file <%@taglib prefix="googlemaps" uri="/WEB-INF/googlemaps" %> And have then included this where I actually want to show a map on my jsp <googlemaps:map id="map" width="250" height="300" version="2" type="STREET" zoom="12"> <googlemaps:key domain="localhost" key="xxxx"/> <googlemaps:point id="point1" address="74 Connors Lane" city="Elkton" state="MD" zipcode="21921" country="US"/> <googlemaps:marker id="marker1" point="point1"/> </googlemaps:map> But when I load up my application, I get the following error. org.apache.jasper.JasperException: /jsp/dashboard.jsp(1,1) /jsp/common/taglibs.jsp(6,56) PWC6117: File "/WEB-INF/googlemaps" not found root cause org.apache.jasper.JasperException: /jsp/common/taglibs.jsp(6,56) PWC6117: File "/WEB-INF/googlemaps" not found Have I missed something simple? I'm unable to spot what I've done wrong so far.. Thanks
