  • Does Java have an equivalent to .NET resource (.resx) files for localization?

    - by frankadelic
    Does Java have an equivalent to .NET resource (.resx) files for localization? In .NET, you can define resources as key-value pairs within a standard XML document. The resource files are named according to the culture. For example: myresources.resx myresources.en-us.resx myresources.fr-fr.resx myresources.de-de.resx Is there an equivalent in Java? Are the similar naming conventions used for files?

  • R Install/Update on Mac OS X (Snow Leopard): where does R put files during install/config?

    - by doug
    In sum, there's a stray preference-like file or two (probably just one) that i can't find. Here's the whole story: I recently attempted to update my R install from 2.10 to 2.11. As i have done before, i installed from source. I know that all of the dependencies are correctly installed and made available to R, because my prior install worked fine. When i upgraded to 2.11, i am unable to install packages (no exception thrown, it just doesn't appear to complete the install and is unresponsive so i have to quit + restart R. Given i install from source, there are any number of points in the process that i could have messed up. What i need to do now is "start over" which requires that i clear out my my prior install. I am having trouble doing that. There is still at least one preference file or something like that i can't find and one of these is causing the problem, so i need to find it and terminate it with extreme prejudice before i do a fresh install. Although i set a number of flags during the install, i have never opted out of the default install locations during the config step. There has to be one or more preference files still in my file structure (and that's also accessible to the new install of R) because after i follow all of the steps below, then do a fresh install, when i start R for the first time, some of my preferences have persisted (e.g., quartz settings, GUI background color, editor selection, etc.). Again, the problem is that i just cannot locate those files. Finally, the problem can't be that during my last install from source, i inadvertently caused a preference file to be sent to an off-spec location--because again, a fresh R install (whether from source or from the OS X binaries) is finding those files Here's what i've done prior to attempting a clean install of R: Removed files from these locations: ~/.RData ~/.RHistory /Applications/R64.app /Applications/R.app /Library/Frameworks/R.framework (i also removed all symlinks from these) Cleared all RAM and disk caches, in particular the directory where i know R caches: ~/Library/Caches/R* (in fact i've cleared this entire directory) Checked for all 'hidden' files in the OS X directories where login/startup files are often placed: /etc/ ~/ In addition, i've checked R-help, and i've also read through the relevant portions of 'R Installation and Administration'--no luck. I've also searched searched my file structure using the various bash utilities, which nearly always solves problems of this sort quite easily, but in this case obviously searching by name or even pattern is more problematic.

  • iphone: how do I obtain a list of all files with a given extension on the app's document folder?

    - by Mike
    I have saved all my files using something like this NSString *fileName = [NSString stringWithFormat:@"%@.plist", myName]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *appFile = [documentsDirectory stringByAppendingPathComponent:fileName]; [myDict writeToFile:appFile atomically:YES]) //where myDic is a dictionary containing the value of all parameters I would like to save. All these files were saved with the .plist extension. The same directory contains several JPG and PNG files. Now, how do I retrieve the list of all .plist files on that directory? thanks for any help.

    - by Lance711
    Welcome to OpenWorld! OpenWorld 2012 got underway today with a series of meetings with the members of the WebCenter Customer Advisory Board. Led by the WebCenter Product Management team, these meetings are a great way for the product team and customers to directly interact and discuss real-life business challenges, product details and to discuss upcoming features and functionality. This year, board members participated in discussions around live demos around product enhancements that will be featured throughout the coming week. Highlights included a variety of new mobile and social solutions, a great new user interface for WebCenter Content plus new Portal and Sites functionality that makes the experience for the everyday user a lot more pleasant. The day kicked off with Roel Stalman, VP of Product Management, giving a detailed overview of what’s new in WebCenter. Given all the improvements to discuss, this session went over 2 hours! Roel showcased the brand new UI for Content, Portal and Sites. He also gave live demos of the new mobile apps for WebCenter Content, Portal and the Oracle Social Network.  The attendees then broke into sub-groups in order to deep-dive with Product Management for the Portal, Sites, and Content product areas on specific functionality and application integrations. If you are here in San Francisco this week for OpenWorld, I definitely recommend stopping by the WebCenter area in the Moscone West Exhibition Hall to see some of this new functionality for yourself. And be sure to check out the WebCenter sessions throughout the week as those give us a chance to discuss direction and strategy, answer your questions and get your feedback and ideas. For those of you could not make it to OpenWorld this year, we miss you! You can stay in touch with what is happening via this blog and by following #oow and #webcenter on Twitter. Additionally, we will be rolling out details on upcoming products and release info over the coming months via this blog and web seminars. Stay tuned!

  • How to walk through two files simultaneously in Perl?

    - by Alex Reynolds
    I have two text files that contain columnar data of the variety position-value. Here is an example of the first file (file A): 100 1 101 1 102 0 103 2 104 1 ... Here is an example of the second file (B): 20 0 21 0 ... 100 2 101 1 192 3 193 1 ... Instead of reading one of the two files into a hash table, which is prohibitive due to memory constraints, what I would like to do is walk through two files simultaneously, in a stepwise fashion. What this means is that I would like to stream through lines of either A or B and compare position values. If the two positions are equal, then I perform a calculation on the values associated with that position. Otherwise, if the positions are not equal, I move through lines of file A or file B until the positions are equal (when I again perform my calculation) or I reach EOF of both files. Is there a way to do this in Perl?

  • Java EE and GlassFish Server Roadmap Update

    - by John Clingan
    2013 has been a stellar year for both the Java EE and GlassFish Server communities. On June 12, Oracle and its partners announced the release of Java EE 7, which delivers on three major themes – HTML5, developer productivity, and meeting enterprise demands. The online event attracted over 10,000 views in the first two days! During the online event, Oracle also announced the availability of GlassFish Server Open Source Edition 4, the world's first Java EE 7 compatible application server. The primary role of GlassFish Server Open Source Edition has been, and continues to be, driving adoption of the latest release of the Java Platform, Enterprise Edition. Oracle also announced the Java EE 7 SDK, which bundles GlassFish Server Open Source Edition 4, as a Java EE 7 learning aid. Last, Oracle publicly announced the Java EE 7 reference implementation based on GlassFish Server Open Source Edition 4. Java EE is a popular platform, as evidenced by the 20+ Java EE 6 compatible implementations available to choose from. After the launch of Java EE 7 and GlassFish Server Open Source Edition 4, we began planning the Java EE 8 roadmap, which was covered during the JavaOne Strategy Keynote. To summarize, there is a lot of interest in improving on HTML5 support, Cloud, and investigating NoSQL support. We received a lot of great feedback from the community and customers on what they would like to see in Java EE 8. As we approached JavaOne 2013, we started planning the GlassFish Server roadmap. What we announced at JavaOne was that GlassFish Server Open Source Edition 4.1 is scheduled for 2014. Here is an update to that roadmap. GlassFish Server Open Source Edition 4.1 is scheduled for 2014 We are planning updates as needed to GlassFish Server Open Source Edition, which is commercially unsupported As we head towards Java EE 8: The trunk will eventually transition to GlassFish Server Open Source Edition 5 as a Java EE 8 implementation The Java EE 8 Reference Implementation will be derived from GlassFish Server Open Source Edition 5. This replicates what has been done in past Java EE and GlassFish Server releases. Oracle will no longer release future major releases of Oracle GlassFish Server with commercial support – specifically Oracle GlassFish Server 4.x with commercial Java EE 7 support will not be released. Commercial Java EE 7 support will be provided from WebLogic Server. Oracle GlassFish Server will not be releasing a 4.x commercial version Expanding on that last bullet, new and existing Oracle GlassFish Server 2.1.x and 3.1.x commercial customers will continue to be supported according to the Oracle Lifetime Support Policy. Oracle recommends that existing commercial Oracle GlassFish Server customers begin planning to move to Oracle WebLogic Server, which is a natural technical and license migration path forward: Applications developed to Java EE standards can be deployed to both GlassFish Server and Oracle WebLogic Server GlassFish Server and Oracle WebLogic Server have implementation-specific deployment descriptor interoperability (here and here). GlassFish Server 3.x and Oracle WebLogic Server share quite a bit of code, so there are quite a bit of configuration and (extended) feature similarities. Shared code includes JPA, JAX-RS, WebSockets (pre JSR 356 in both cases), CDI, Bean Validation, JAX-WS, JAXB, and WS-AT. Both Oracle GlassFish Server 3.x and Oracle WebLogic Server 12c support Oracle Access Manager, Oracle Coherence, Oracle Directory Server, Oracle Virtual Directory, Oracle Database, Oracle Enterprise Manager and are entitled to support for the underlying Oracle JDK. To summarize, Oracle is committed to the future of Java EE.  Java EE 7 has been released and planning for Java EE 8 has begun. GlassFish Server Open Source Edition continues to be the strategic foundation for Java EE reference implementation going forward. And for developers, updates will be delivered as needed to continue to deliver a great developer experience for GlassFish Server Open Source Edition. We are planning for GlassFish Server Open Source Edition 5 as the foundation for the Java EE 8 reference implementation, as well as bundling GlassFish Server Open Source Edition 5 in a Java EE 8 SDK, which is the most popular distribution of GlassFish. This will allow GlassFish releases to be more focused on the Java EE platform and community-driven requirements. We continue to encourage community contributions, bug reports, participation on the GlassFish forum, etc. Going forward, Oracle WebLogic Server will be the single strategic commercially supported application server from Oracle. Disclaimer: The preceding is intended to outline our general product direction. It is intended for information purposes only, and may not be incorporated into any contract.It is not a commitment to deliver any material, code, or functionality, and should not be relied upon in making purchasing decisions.

  • How do I copy new binaries to C:\Program Files?

    - by Michael L Perry
    I'm creating a Windows app that automatically updates itself. I'm not using ClickOnce for a variety of reasons. When I try to File.Move() my updated files to C:\Program Files on Windows 7, I get the following error: Access to the path 'C:\Program Files\<company>\<app>\<app.exe>' is denied. I am not given a UAC prompt. The exe that I am trying to update is not currently running.

  • How do you stop a user-instance of Sql Server? (Sql Express user instance database files locked, eve

    - by Bittercoder
    When using SQL Server Express 2005's User Instance feature with a connection string like this: <add name="Default" connectionString="Data Source=.\SQLExpress; AttachDbFilename=C:\My App\Data\MyApp.mdf; Initial Catalog=MyApp; User Instance=True; MultipleActiveResultSets=true; Trusted_Connection=Yes;" /> We find that we can't copy the database files MyApp.mdf and MyApp_Log.ldf (because they're locked) even after stopping the SqlExpress service, and have to resort to setting the SqlExpress service from automatic to manual startup mode, and then restarting the machine, before we can then copy the files. It was my understanding that stopping the SqlExpress service should stop all the user instances as well, which should release the locks on those files. But this does not seem to be the case - could anyone shed some light on how to stop a user instance, such that it's database files are no longer locked? Update OK, I stopped being lazy and fired up Process Explorer. Lock was held by sqlserver.exe - but there are two instances of sql server: sqlserver.exe PID: 4680 User Name: DefaultAppPool sqlserver.exe PID: 4644 User Name: NETWORK SERVICE The file is open by the sqlserver.exe instance with the PID: 4680 Stopping the "SQL Server (SQLEXPRESS)" service, killed off the process with PID: 4644, but left PID: 4680 alone. Seeing as the owner of the remaining process was DefaultAppPool, next thing I tried was stopping IIS (this database is being used from an ASP.Net application). Unfortunately this didn't kill the process off either. Manually killing off the remaining sql server process does remove the open file handle on the database files, allowing them to be copied/moved. Unfortunately I wish to copy/restore those files in some pre/post install tasks of a WiX installer - as such I was hoping there might be a way to achieve this by stopping a windows service, rather then having to shell out to kill all instances of sqlserver.exe as that poses some problems: Killing all the sqlserver.exe instances may have undesirable consequencies for users with other Sql Server instances on their machines. I can't restart those instances easily. Introduces additional complexities into the installer. Does anyone have any further thoughts on how to shutdown instances of sql server associated with a specific user instance?

  • How can I sync files in two different git repositories (not clones) and maintain history?

    - by brian d foy
    I maintain two different git repos that need to share some files, and I'd like the commits in one repo to show up in the other. What's a good way to do that for ongoing maintenance? I've been one of the maintainers of the perlfaq (Github), and recently I fell into the role of maintaining the Perl core documentation, which is also in git. Long before I started maintaining the perlfaq, it lived in a separate source control repository. I recently converted that to git. Periodically, one of the perl5-porters would sync the shared files in the perlfaq repo and the perl repo. Since we've switched to git, we'e been a bit lazy converting the tools, and I'm now the one who does that. For the time being, the two repos are going to stay separate. Currently, to sync the FAQ for a new (monthly) release of perl, I'm almost ashamed to say that I merely copy the perlfaq*.pod files in the perlfaq repo and overlay them in the perl repo. That loses history, etc. Additionally, sometimes someone makes a change to those files in the perl repo and I end up overwriting it (yes, check git diff you idiot!). The files do not have the same paths in the repo, but that's something that I could change, I think. What I'd like to do, in the magical universe of rainbows and ponies, is pull the objects from the perlfaq repo and apply them in the perl repo, and vice-versa, so the history and commit ids correspond in each. Creating patches works, but it's also a lot work to manage it Git submodules seem to only work to pull in the entire external repo I haven't found something like svn's file externals, but that would work in both directions anyway I'd love to just fetch objects from one and cherry-pick them in the other What's a good way to manage this?

  • Which SCM/VCS cope well with moving text between files?

    - by pfctdayelise
    We are having havoc with our project at work, because our VCS is doing some awful merging when we move information across files. The scenario is thus: You have lots of files that, say, contain information about terms from a dictionary, so you have a file for each letter of the alphabet. Users entering terms blindly follow the dictionary order, so they will put an entry like "kick the bucket" under B if that is where the dictionary happened to list it (or it might have been listed under both B, bucket and K, kick). Later, other users move the terms to their correct files. Lots of work is being done on the dictionary terms all the time. e.g. User A may have taken the B file and elaborated on the "kick the bucket" entry. User B took the B and K files, and moved the "kick the bucket" entry to the K file. Whichever order they end up getting committed in, the VCS will probably lose entries and not "figure out" that an entry has been moved. (These entries are later automatically converted to an SQL database. But they are kept in a "human friendly" form for working on them, with lots of comments, examples etc. So it is not acceptable to say "make your users enter SQL directly".) It is so bad that we have taken to almost manually merging these kinds of files now, because we can't trust our VCS. :( So what is the solution? I would love to hear that there is a VCS that could cope with this. Or a better merge algorithm? Or otherwise, maybe someone can suggest a better workflow or file arrangement to try and avoid this problem?

  • Any downsides to UPX-ing my 32-bit Python 2.6.4 development environment EXE/PYD/DLL files?

    - by Malcolm
    Are there any downsides to UPX-ing my 32-bit Python 2.6.4 development environment EXE/PYD/DLL files? The reason I'm asking is that I frequently use a custom PY2EXE script that UPX's copies of these files on every build. Yes, I could get fancy and try to cache UPXed files, but I think a simpler, safer, and higher performance solution would be for me to just UPX my Python 2.6.4 directory once and be done with it. Thoughts? Malcolm

  • Why does this script not open parallel gnome-terminals on a server?

    - by broiyan
    Why am I not able to have parallel gnome-terminals on my server while I can on my client. Here is a test that illustrates the problem. #!/bin/bash # this is the parent script gnome-terminal --command "./left.sh" sleep 10 gnome-terminal --command "./right.sh" #!/bin/bash echo "this is the left script" read -p "press any key to close this terminal" key #!/bin/bash echo "this is the right script" read -p "press any key to close this terminal" key When I run this on a regular ubuntu desktop (maverick) I see two terminals after 10 seconds. When I run this on a maverick server at a server farm, the second window does not appear until after I close the first one and wait 10 seconds. I am using tightvncserver to view the server desktop. (I could have simplified a bit more. The 10 second sleep is extraneous to the problem. In my real world application I need the first terminal to do some real work before starting the second. The problem probably still exists even if there is no sleep.)

  • Ever since installing Ubuntu Accomplishments, RSSOwl won't open without crashing. Why?

    - by Edd Baisley
    I'm running Ubuntu 12.04 on an older machine, so I am accustomed to not being able to run resource-heavy apps well, or at all. However, RSSOwl had been running like a champ up until the moment I installed Ubuntu Accomplishments. I'm not the most code savvy, but I don't see what one of these would have to do with the other. I have already tried removing and re-installing RSSOwl, to no avail, and I'd rather not have to uninstall Accomplishments, because I love trophies of all kinds. Any ideas?

  • Why would it be a bad idea to have database connection open between client requests?

    - by AspOnMyNet
    1) Book I’m reading argues that connections shouldn’t be opened between client requests, since they are a finite resource. I realize that max pool size can quickly be reached and thus any further attempts to open a connection will be queued until connection becomes available and for that reason it would be imperative that we release connection as soon as possible. But assuming all request will open connection to the same DB, then I’m not sure how having a connection open between two client requests would be any less efficient than having each request first acquiring a connection from connection pool and later returning that object to connection pool? 2) Book also recommends that when database code is encapsulated in a dedicated data access class, then method M opening a database connection should also close that connection. a) I assume one reason why M should also close it, is because if method M opening the connection doesn’t also close it, but instead this connection object is used inside several methods, then it’s more likely that a programmer will forget to close it. b) Are there any other reasons why a method opening the connection should also close it? thanx

  • Where Are the Release Versions of ASP.Net AJAX 4.0 Templating Files?

    - by Lee Richardson
    I'm trying to get the production version of ASP.Net AJAX 4.0 Templating working and can't find the JavaScript files. With the beta version I needed to reference MicrosoftAjaxTemplates.js, MicrosoftAjaxAdoNet.js, and MicrosoftAjaxDataContext.js. I can get everything to work with the beta CDN versions (e.g. http://ajax.microsoft.com/ajax/beta/0911/MicrosoftAjaxTemplates.js). But for the life of me I can't find 1. The release CDN versions of these files or 2. Where to download the whole Release ASP.Net AJAX 4.0 JavaScript package. The files certainly are not listed on the ASP.Net AJAX 4.0 CDN at http://www.asp.net/ajaxlibrary/CDNAjax4.ashx. Maybe the files have been renamed? Theoretically this should be a rediculously easy question and I'm a little embarrased to even ask it on StackOverflow, but I've had no luck finding an answer on my own. Any help would be much appreciated. Thanks, - Lee

  • How can I copy/paste files via RDP in Kubuntu?

    - by Dai
    I recently installed the latest Kubuntu (x64) on my work machine as I am trying to migrate away from Windows. Unfortunately I use RDP very frequently to connect to customer's servers and need to be able to copy files across. I have tried the following packages with no luck: remmina rdesktop xfreerdp My latest attempt to solve this involved connecting one of my folders to the remote server, here is the command I used to launch rdesktop: rdesktop -5 -K -r disk:home=/home/dai -r clipboard:CLIPBOARD -r sound:off -x l -P 192.168.0.2 -u "administrator" -p pass The servers are not all running the same version of Windows, the one I've been trying so far is running Server 2003 R2. Customer servers range from Server 2000 to Server 2008. I've been Googling this like mad but all the solutions I find seem to fail, maybe because almost all the help out there assumes that I'm running Gnome. Sorry if this is a stupid question. Thanks in advance for your help. Edit: Copying and pasting text seems to work just fine, but that's not what I need.

Let me give an example - When I want to add an image to an article on my blog, I click "Browse" button in the image uploader, and then upload the image to the blog. The problem is, when I want to upload another image to my blog, I want the browser to look into the same directory; but it's always takes me to the "Recently Used" directory. Is there a way to change this? I hope I have made myself clear enough. EDIT: I only use Chrome, so I am referring to it.

  • Should tests be in the same ruby file or in separeted ruby files?

    While using Selenium and Ruby to do some functional tests, I am worried with the performance. So is it better to add all test methods in the same ruby file, or I should put each one in separated code files? Below a sample with all tests in the same file: # encoding: utf-8 require "selenium-webdriver" require "test/unit" class Tests < Test::Unit::TestCase def setup @driver = Selenium::WebDriver.for :firefox @base_url = "http://mysite" @driver.manage.timeouts.implicit_wait = 30 @verification_errors = [] @wait = Selenium::WebDriver::Wait.new :timeout => 10 end def teardown @driver.quit assert_equal [], @verification_errors end def element_present?(how, what) @driver.find_element(how, what) true rescue Selenium::WebDriver::Error::NoSuchElementError false end def verify(&blk) yield rescue Test::Unit::AssertionFailedError => ex @verification_errors << ex end def test_1 @driver.get(@base_url + "/") # a huge test here end def test_2 @driver.get(@base_url + "/") # a huge test here end def test_3 @driver.get(@base_url + "/") # a huge test here end def test_4 @driver.get(@base_url + "/") # a huge test here end def test_5 @driver.get(@base_url + "/") # a huge test here end end

  • Yippy &ndash; the F# MVVM Pattern

    - by MarkPearl
    I did a recent post on implementing WPF with F#. Today I would like to expand on this posting to give a simple implementation of the MVVM pattern in F#. A good read about this topic can also be found on Dean Chalk’s blog although my example of the pattern is possibly simpler. With the MVVM pattern one typically has 3 segments, the view, viewmodel and model. With the beauty of WPF binding one is able to link the state based viewmodel to the view. In my implementation I have kept the same principles. I have a view (MainView.xaml), and and a ViewModel (MainViewModel.fs).     What I would really like to illustrate in this posting is the binding between the View and the ViewModel so I am going to jump to that… In Program.fs I have the following code… module Program open System open System.Windows open System.Windows.Controls open System.Windows.Markup open myViewModels // Create the View and bind it to the View Model let myView = Application.LoadComponent(new System.Uri("/FSharpWPF;component/MainView.xaml", System.UriKind.Relative)) :?> Window myView.DataContext <- new MainViewModel() :> obj // Application Entry point [<STAThread>] [<EntryPoint>] let main(_) = (new Application()).Run(myView) You can see that I have simply created the view (myView) and then created an instance of my viewmodel (MainViewModel) and then bound it to the data context with the code… myView.DataContext <- new MainViewModel() :> obj If I have a look at my viewmodel (MainViewModel) it looks like this… module myViewModels open System open System.Windows open System.Windows.Input open System.ComponentModel open ViewModelBase type MainViewModel() = // private variables let mutable _title = "Bound Data to Textbox" // public properties member x.Title with get() = _title and set(v) = _title <- v // public commands member x.MyCommand = new FuncCommand ( (fun d -> true), (fun e -> x.ShowMessage) ) // public methods member public x.ShowMessage = let msg = MessageBox.Show(x.Title) () I have exposed a few things, namely a property called Title that is mutable, a command and a method called ShowMessage that simply pops up a message box when called. If I then look at my view which I have created in xaml (MainView.xaml) it looks as follows… <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="F# WPF MVVM" Height="350" Width="525"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <TextBox Text="{Binding Path=Title, Mode=TwoWay}" Grid.Row="0"/> <Button Command="{Binding MyCommand}" Grid.Row="1"> <TextBlock Text="Click Me"/> </Button> </Grid> </Window>   It is also very simple. It has a button that’s command is bound to the MyCommand and a textbox that has its text bound to the Title property. One other module that I have created is my ViewModelBase. Right now it is used to store my commanding function but I would look to expand on it at a later stage to implement other commonly used functions… module ViewModelBase open System open System.Windows open System.Windows.Input open System.ComponentModel type FuncCommand (canExec:(obj -> bool),doExec:(obj -> unit)) = let cecEvent = new DelegateEvent<EventHandler>() interface ICommand with [<CLIEvent>] member x.CanExecuteChanged = cecEvent.Publish member x.CanExecute arg = canExec(arg) member x.Execute arg = doExec(arg) Put this all together and you have a basic project that implements the MVVM pattern in F#. For me this is quite exciting as it turned out to be a lot simpler to do than I originally thought possible. Also because I have my view in XAML I can use the XAML designer to design forms in F# which I believe is a much cleaner way to go rather than implementing it all in code. Finally if I look at my viewmodel code, it is actually quite clean and compact…
