  • Where to start when digging into an existing J2EE codebase?

    - by Jacob Krustchinsky
    I work for a company that produces enterprise applications to be used by schools and districts to manage all of their tests and standards data. Their existing application is written in J2EE and is very large. I personally am a seasoned PHP and Ruby = RoR developer and I have been asked to attempt to implement easily added but crucial features to an existing J2EE codebase. I am very familiar with Java SE and know the architecture of a web application well. What I am asking for is, will this suffice for the task ahead and what tips can you give me in digging into the code base and actually efficiently adding these new features? Is there anything important I need to know before beginning and what can I expect in terms of problems and issues coming from a Java SE, PHP, RoR background? Time isn't too much of an issue, I should have plenty of time to familiarize myself with J2EE.Please also note, syntax will not be a problem here.

  • Ubuntu 14.04 LTS AMD64 randomly uninstals packages / applications

    - by Jacob Lindeen
    I am having a strange issue. Occasionally when installing new packages, I will get a system crash notification which I will report. The environment then becomes unstable, unity crashes and all open windows, loose title bars, and the main launcher shuts down. I usually have to run the command unity --replace to restore functionality, but ultimately end up having to reboot. Upon booting back up I find all of my user-installed packages are gone and I have to reinstall them via apt. Please tell me someone else is having this issue, because this is the second system and third install I have had this issue on.

  • determine an application's process name on linux (ubuntu)

    - by Jacob
    This is the situation: Working on (the next version of) a Unity quicklist editor, I would like to add a reliable way of "restarting" launcher icons. To do so, I need to remove the icon (editing gsettings) and replace it on the same position. So far no problem. However, if the application in question is running, user will possibly lose data, as the application will quit when it's icon is removed from the launcher. What I need is a reliable way to find an application's process name, to let the editor check in the list of running processes if the application is running, and send a warning message to the user that the icon can not be restarted if the application is running. What i did so far is make the editor look into the desktop file, to read the command, also read the command, stripped from the directory section, and furthermore look into possible remote scripts the desktop file command might refer to, looking for strings starting with "./" Although te method seems to work well with all applications I tested it on, I have the feeling there must be an easier way to cover the problem in an "all in one" way... Is there? also suggestions to catch more exceptional situations are welcome!

  • building a gl3 app under cygwin

    - by user445264
    i've got a small opengl 3.2 app that i've been developing on linux using the standard gnu tools (gmake/gcc). the code seems pretty portable--i had no problems running it on osx until i started using gl3 features that the mac mini gl drivers don't seem to support. i've got a bootcamp partition with windows xp on the same mini, and i'd like to run my app there if possible. the windows drivers definitely support gl 3.2, but i'm having trouble linking. this seems like a really common issue, but i haven't found any answers online that address using opengl 1.2 under cygwin. i'm using glew-1.5.5 and linking like so: g++ -o glToy *.o -L/cygdrive/c/Program\ Files/glew-1.5.5/lib -lglew32 -lglut32 -lglu32 -lopengl32 but i get a whole lot of this sort of output: Program.o:/home/Jacob/glToy/Program.cpp:134: undefined reference to `__imp____glewUseProgram' Program.o:/home/Jacob/glToy/Program.cpp:235: undefined reference to `__imp____glewActiveTexture' Program.o:/home/Jacob/glToy/Program.cpp:73: undefined reference to `__imp____glewGetShaderiv' ... any ideas what i'm doing wrong? or perhaps this isn't a workable setup? other ideas for getting this going on the mac mini (2009 version)? thanks!

  • I install Ubuntu 13.10 and reboot and im on KDE desktop?

    - by jgamer578
    Hi I'm Jacob and I have no idea what's going on. I installed Ubuntu 13.10 today and was playing around with it for a while and dl'd a bunch of apps from software center and stuff. Eventually I installed steam and (finally) got it working. I downloaded TF2 and had some weird issue where the screen got so distorted to the point I could not play. So I dl'd a driver for my graphics card from the additional drivers app (or whatever it's called) and when it was done I restarted my computer (because it said to.) When the PC booted up it loaded the KDE desktop and I have no idea why. I had unity before I rebooted. Ubuntu 13.10 is the only OS installed on my PC, and I still have all the apps that I downloaded, but I kinda like unity (I started using Ubuntu after they switched to unity) and want it back. Thanks for reading and any help in advance, Jacob.

  • Need a little help with sound in a JApplet

    - by jacob schuschel
    I am working on a solitaire game in Java, and i need to implement sound when the desk is shuffled, card flipped, etc. I used the following sites as reference to try and get it to work, but i am getting Null Pointer Exceptions or mishandled URL exception (depending on what i tweak). here Also, i am using netbeans 6.7.1 as my IDE. I will try to break down the code and explain: package cardgame; import java.applet.*; import java.util.logging.Level; import java.util.logging.Logger; import javax.swing.JApplet; import javax.swing.*; import java.io.*; import java.net.*; /** * * @author jacob */ public class Sound extends JApplet { private AudioClip song; // Sound player private String URL = null; private URL songPath; // Sound path /* *sound_1 = shuffling cards *sound_2 = to discard *sound_3 = from discard *sound_4 = cardflip 1 *sound_5 = cardflip 2 */ Sound(String filename) { try { songPath = new URL(getCodeBase(),filename); // Get the Sound URL } catch (MalformedURLException ex) { Logger.getLogger(Sound.class.getName()).log(Level.SEVERE, null, ex); } song = getAudioClip(songPath); // Load the Sound } Sound(int i) { URL = "./sounds/sound_" + i + ".wav"; System.out.println(URL); try { songPath = new URL(URL); // Get the Sound URL song = getAudioClip(songPath); } catch (MalformedURLException ex) { Logger.getLogger(Sound.class.getName()).log(Level.SEVERE, null, ex); } } public void playSound() { song.loop(); // Play } public void stopSound() { song.stop(); // Stop } public void playSoundOnce() { song.play(); // Play only once } } The 2 different construcors are for different ways i tried to implement this. The first one creates the filepath, and passes it in. The second one builds the filepath in the constructor, given a sound # (i made a list of what numbers correspond to what sound for reference). I am getting the followig errors out: ./sounds/sound_1.wav Nov 16, 2009 4:14:13 PM cardgame.Sound ./sounds/sound_2.wav SEVERE: null java.net.MalformedURLException: no protocol: ./sounds/sound_1.wav ./sounds/sound_3.wav at java.net.URL.(URL.java:583) at java.net.URL.(URL.java:480) at java.net.URL.(URL.java:429) ./sounds/sound_4.wav ./sounds/sound_5.wav at cardgame.Sound.(Sound.java:46) at cardgame.Game.loadSounds(Game.java:712) at cardgame.Game.(Game.java:62) at cardgame.Main.main(Main.java:25) Nov 16, 2009 4:14:13 PM cardgame.Sound SEVERE: null java.net.MalformedURLException: no protocol: ./sounds/sound_2.wav at java.net.URL.(URL.java:583) at java.net.URL.(URL.java:480) at java.net.URL.(URL.java:429) at cardgame.Sound.(Sound.java:46) at cardgame.Game.loadSounds(Game.java:712) at cardgame.Game.(Game.java:62) at cardgame.Main.main(Main.java:25) Nov 16, 2009 4:14:13 PM cardgame.Sound SEVERE: null java.net.MalformedURLException: no protocol: ./sounds/sound_3.wav at java.net.URL.(URL.java:583) at java.net.URL.(URL.java:480) at java.net.URL.(URL.java:429) at cardgame.Sound.(Sound.java:46) at cardgame.Game.loadSounds(Game.java:712) at cardgame.Game.(Game.java:62) at cardgame.Main.main(Main.java:25) Nov 16, 2009 4:14:13 PM cardgame.Sound SEVERE: null java.net.MalformedURLException: no protocol: ./sounds/sound_4.wav at java.net.URL.(URL.java:583) at java.net.URL.(URL.java:480) at java.net.URL.(URL.java:429) at cardgame.Sound.(Sound.java:46) at cardgame.Game.loadSounds(Game.java:712) at cardgame.Game.(Game.java:62) at cardgame.Main.main(Main.java:25) Nov 16, 2009 4:14:13 PM cardgame.Sound SEVERE: null java.net.MalformedURLException: no protocol: ./sounds/sound_5.wav at java.net.URL.(URL.java:583) at java.net.URL.(URL.java:480) at java.net.URL.(URL.java:429) at cardgame.Sound.(Sound.java:46) at cardgame.Game.loadSounds(Game.java:712) at cardgame.Game.(Game.java:62) at cardgame.Main.main(Main.java:25) Thanks for those who read and more thanks to those who help.

  • Missing help files for Microsoft.WindowsMobile in Visual Studio 2008 help system

    - by Johann Gerell
    I've just installed the Windows Mobile 6.5.3 DTK, both standard and professional. Before that I had the standard and professional Windows Mobile 6 SDKs. All Windows Mobile help pages are missing in Visual Studio 2008's help system - in particular everything in the Microsoft.WindowsMobile namespace. Microsoft.WindowsMobile.DirectX is there, but it's not part of the Windows Mobile 6 SDK or 6.5.3 DTK. If I open the WM6 docs from the freshly created program group, then it's all fine and dandy, but there doesn't seem to have been a proper integration with VS during installation. Any ideas what's gone wrong and how to fix it?

  • Using IOC in a remoting scenario

    - by Christoph
    I'm struggling with getting IOC to work in a remoting scenario. I have my application server set up to publish Services (SingleCall) which are configured via XML. This works just like this as we all know: RemotingConfiguration.Configure(ConfigFile, true); lets say my service looks like that (pseudocode) public class TourService : ITourService { IRepository _repository; public TourService() { _repository = new SqlServerRepository(); } } But what I rather would like to have sure looks like this: public class TourService : ITourService { IRepository _repository; public TourService(IRepository repository) { _repository = repository; } } On the client side we do something like that (pseudocode again): (ITourService)Activator.GetObject(ITourService, tcp://server/uri); This prompts the server to create a new instance of my TourService class... However this doesn't seem to work out well because the .NET Remoting Infrastructure want's to know the type it should publish but I would rather like to point it to the way how it could retrieve the object it should publish. In other words, route it through the IOC process pipe of - let's say windsor castle - for example. Currently I'm a bit lost on that task...

  • PROPSHEETHEADER and PSH_PIVOT to get the horizontal pivot scroll?

    - by Johann Gerell
    Windows Mobile 6.5.3 has a "touch friendlier" pivot at the top of the screen instead of tabs at the bottom. In the docs for PROPSHEETHEADER, the dwFlag value PSH_PIVOT is documented: PSH_PIVOT Applies to Windows Mobile 6.5.3 Replaces dialog box tabs with a simple pivot (horizontal spinner). It's supposed to bed defined in prsht.h, but it's not. My 6.5.3 and 6 headers differ only in this: #define PSM_GETPIVOTCONTROL (WM_USER + 119) #define PropSheet_GetPivotControl(hDlg) \ (HWND)SNDMSG(hDlg, PSM_GETPIVOTCONTROL, 0, 0) which is in the 6.5.3 prsht.h, but not in the 6 one. What's the value of PSH_PIVOT? Did they forget to include it?

  • Unit testing .Net CF apps on Windows Mobile 6.5.3 in Visual Studio 2008

    - by Johann Gerell
    Did anyone get that to work? I mean, unit testing .Net CF apps on Windows Mobile 6.5.3 in Visual Studio 2008. It works great for a WM 6 Pro target, but not for a WM 6.5.3 target. I get this error: The test adapter ('Microsoft.VisualStudio.TestTools.TestTypes.Unit.UnitTestAdapter, Microsoft.VisualStudio.QualityTools.Tips.UnitTest.Adapter, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a') required to execute this test could not be loaded. Check that the test adapter is installed properly. Not enough storage is available to process this command. Yes, I can read the error text, but I don't understand the failed run. Any clues?

  • Why isn't the reference counter in boost::shared_ptr volatile?

    - by Johann Gerell
    In the boost::shared_ptr destructor, this is done: if(--*pn == 0) { boost::checked_delete(px); delete pn; } where pn is a pointer to the reference counter, which is typedefed as shared_ptr::count_type -> detail::atomic_count -> long I would have expected the long to be volatile long, given threaded usage and the non-atomic 0-check-and-deletion in the shared_ptr destructor above. Why isn't it volatile?

  • How to get "all" (or the MAIN/LAUNCHER) android intent

    - by Christoph Jerolimov
    Hey, i want receive all start app intents (i think MAIN/LAUNCHER, see below) to log how often i used the application. So i do not want create an activity... I tried several receiver blocks, but for now nothing works: with, without priority, only the action, both, only the category and so on.. <receiver android:name=".Receiver" android:enabled="true" android:process=".e"> <intent-filter priority="100000" android:priority="100000"> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </receiver> Have anyone an idea? Thanks

  • Is there a better way to convert SQL datetime from hh:mm:ss to hhmmss?

    - by Johann J.
    I have to write an SQL view that returns the time part of a datetime column as a string in the format hhmmss (apparently SAP BW doesn't understand hh:mm:ss). This code is the SAP recommended way to do this, but I think there must be a better, more elegant way to accomplish this TIME = case len(convert(varchar(2), datepart(hh, timecolumn))) when 1 then /* Hour Part of TIMES */ case convert(varchar(2), datepart(hh, timecolumn)) when '0' then '24' /* Map 00 to 24 ( TIMES ) */ else '0' + convert(varchar(1), datepart(hh, timecolumn)) end else convert(varchar(2), datepart(hh, timecolumn)) end + case len(convert(varchar(2), datepart(mi, timecolumn))) when 1 then '0' + convert(varchar(1), datepart(mi, timecolumn)) else convert(varchar(2), datepart(mi, timecolumn)) end + case len(convert(varchar(2), datepart(ss, timecolumn))) when 1 then '0' + convert(varchar(1), datepart(ss, timecolumn)) else convert(varchar(2), datepart(ss, timecolumn)) end This accomplishes the desired result, 21:10:45 is displayed as 211045. I'd love for something more compact and easily readable but so far I've come up with nothing that works.

  • boost smart pointers and BOOST_NO_MEMBER_TEMPLATES

    - by Johann Gerell
    After some struggling I managed to get boost smart pointers to build for Windows CE/Mobile at warning level 4. I found the least-resistance-way to get rid of compile errors and warnings to be #define BOOST_NO_MEMBER_TEMPLATES What does it actually mean? Did I sell my soul to the devil? Will all hell break loose when I actually use the types?

  • VS2010 always thinks project is out of date but nothing has changed

    - by Christoph Ungersböck
    I have a very simmilar problem as described here. I also upgraded a mixed solution of C++/CLI and C# projects from VS2008 to VS2010. And one C++/CLI project always runs out of date. Even if it has been compiled and linked just before and F5 is hit the messagebox "The project is out of date. Would you like to build it?" appears. My pdb settings are set to default value (suggested solution of this problem). Any ideas?

  • Wordpress "Home" link

    - by Johann
    Hi all, I'm working on a Sandbox based Wordpress theme and I would like to add a home link as a first item in the navigation. I know I should change the function in "sandbox_globalnav" in the functions.php file, which is: // Produces a list of pages in the header without whitespace function sandbox_globalnav() { if ( $menu = str_replace( array( "\r", "\n", "\t" ), '', wp_list_pages('title_li=&sort_column=menu_order&echo=0') ) ) $menu = '<ul>' . $menu . '</ul>'; $menu = '<div id="menu">' . $menu . "</div>\n"; echo apply_filters( 'globalnav_menu', $menu ); // Filter to override default globalnav: globalnav_menu } However, my PHP skills are really basic and I'm not sure where I should override this. Thanks!

  • How do I MOVE a circle drawn in a subclass of UIView by overwriting the method "drawRect"??

    - by Christoph v
    hi, I'm trying to figure out what i'm doing wrong but i just don't get it. Here is what i want to do: I want to draw a circle somewhere on the screen of the iphone and then i want the circle always to be displayed at the position where the user currently taps on the screen. I started by creating a subclass of UIView and adding the following lines into the "drawRect" method: - (void)drawRect:(CGRect)rect { //Create the main view! CGContextRef mainscreen = UIGraphicsGetCurrentContext(); //Draw the dot //will be a circle cause rectangle is a square CGRect dotRect = CGRectMake(50, 80, 100, 100); [[UIColor blueColor] set]; CGContextStrokeEllipseInRect(mainscreen, dotRect); CGContextFillEllipseInRect(mainscreen, dotRect); } The appears just fine but now i have no idea how to make it move around on the screen i've tried serveral things and nothing worked pls help!

  • Did anyone give these smart pointers (auto_any, scoped_any, shared_any) a test drive?

    - by Johann Gerell
    I'm investigating smart pointers with "shared" functionality for Windows CE and Mobile, where the VS 2008 tr1 std::shared_ptr cannot be used (due to linkage to a v.9 dll not present on CE, obviously, if I understand it correctly). There's a semi-old MSDN Magazine article with sources from a Microsoftie (Eric Niebler): Achieve More Reliable Resource Management with Our Custom C++ Classes. The reasoning, design and implementation of his shared_any looks solid, but I'm wondering if anyone ever actually tested the lot on any platform (not necessarily WinCe/WM)?

  • Ambiguous access to base class template member function

    - by Johann Gerell
    In Visual Studio 2008, the compiler cannot resolve the call to SetCustomer in _tmain below and make it unambiguous: template <typename TConsumer> struct Producer { void SetConsumer(TConsumer* consumer) { consumer_ = consumer; } TConsumer* consumer_; }; struct AppleConsumer { }; struct MeatConsumer { }; struct ShillyShallyProducer : public Producer<AppleConsumer>, public Producer<MeatConsumer> { }; int _tmain(int argc, _TCHAR* argv[]) { ShillyShallyProducer producer; AppleConsumer consumer; producer.SetConsumer(&consumer); // <--- Ambiguous call!! return 0; } This is the compilation error: // error C2385: ambiguous access of 'SetConsumer' // could be the 'SetConsumer' in base 'Producer<AppleConsumer>' // or could be the 'SetConsumer' in base 'Producer<MeatConsumer>' I thought the template argument lookup mechanism would be smart enough to deduce the correct base Producer. Why isn't it? I could get around this by changing Producer to template <typename TConsumer> struct Producer { template <typename TConsumer2> void SetConsumer(TConsumer2* consumer) { consumer_ = consumer; } TConsumer* consumer_; }; and call SetConsumer as producer.SetConsumer<AppleConsumer>(&consumer); // Unambiguous call!! but it would be nicer if I didn't have to...

  • Drawbacks with reading and writing a big file to or from disk at once instead of small chunks?

    - by Johann Gerell
    I work mainly on Windows and Windows CE based systems, where CreateFile, ReadFile and WriteFile are the work horses, no matter if I'm in native Win32 land or in managed .Net land. I have so far never had any obvious problem writing or reading big files in one chunk, as opposed to looping until several smaller chunks are processed. I usually delegate the IO work to a background thread that notifies me when it's done. But looking at file IO tutorials or "textbook examples", I often find the "loop with small chunks" used without any explanation of why it's used instead of the more obvious (I dare to say!) "do it all at once". Are there any drawbacks to the way I do that I haven't understood?

  • How long will an ASP.NET MVC application run

    - by Christoph
    I wonder how long will an ASP.NET (MVC) application run, when no new requests come in? Lets say I'm using an IOC Container ans have a Singleton Object serving to the clients. As far as I know it will serve different page requests. But how long will it live when no new request come in? Is there any timeout (maybe configured through IIS) that says when my app will shut down?

  • For programming content, what simple-to-use-and-setup PHP based blog are the preferred ones?

    - by Johann Gerell
    I've since long wanted a place I can toss my programming related nuggets at. Every day I feel I solve something that I'll surely hit again in a not so distant future, but by then I most certainly will have forgotten about the previous solution I came up with. So I need to blog it down, quick and dirty, for my own documentation and memory's sake. Must be easy to set up and use. Must handle code syntax and highlighting gracefully for a number of languages, but mainly C# and C++. Must be PHP-based, because that's what my host supplies. I know and have used WordPress (not for code, though), but is it really what I want or need?
