  • Which is the best free ide/plugin for struts2?

    - by shahensha
    Hello friends, I have just learnt struts 2 and now I have taken up a full fledged project in it. I learnt the basics of struts 2 in Netbeans with it's struts2 plugin. But I am not at all happy with it, as it is very basic and I end up doing most of the work. It is obviously better than plain-vanilla text editor, but still not at all near to what netbeans provides for springs and hibernate. I know because netbeans provides native support for springs and hibernate, it is meant to be better. I don't mind changing my IDE if i get better support for struts2! So my questions are Please list all the free IDEs where native support for struts2 is provided. And if possible please compare them. Please list all the plugins that are available for eclipse for struts2 development. I have heard there are better plugins in eclipse. Also, if there are better plugins in any other IDE (other than netbeans or eclipse of course), please list them giving links. Please give me some tips which I'll need before starting a full blown project in Struts2. I haven't worked on any project on Struts2. I have just finished reading Struts 2 in Action of Manning publications. Thanking you in advance! regards shahensha

  • How to sync Ubuntu/software/configurations between N computers with free software and/or without a cloud?

    - by skanatek
    Note: this question is not about syncing data in a Dropbox-like way (files, folders), it is more about syncing configurations. I would like to have exactly the same version of Ubuntu with all the software installed and configured both on my Desktop PC and on my Laptop PC (and maybe on my small netbook PC) without using Ubuntu Sync and with minimal maintenance effort (setup once, run for a long time). The use case is the following: I work on my Laptop PC and do some changes to software configuration, for example: configure vim to have a new plugin update the Search Tracker / Recoll file search index configure Thunderbird to have an additional IMAP account ('remember password') add some new bookmarks in Firefox/Chrome change the desktop background image install new software with apt-get install build and install new software with checkinstall etc. I do some 'sync' operation I switch to my Desktop PC and get all the changes from (1) working on the Desktop PC I work on my Desktop PC and do some changes to software configuration, for example: add new directory to the list of directories to be backed up by DejaDup add a new check spelling dictionary to the Libreoffice Writer configure the Terminator software to have colored fonts install new font into the Ubuntu system configure Ekiga to make phone calls etc. I do some 'sync' operation I switch to my Laptop PC and get all the changes from (1) and (4) working on the Laptop PC. Question: What free/open-source software can I use to sync both machines' Ubuntu systems, installed software and configurations? Is it possible to do that without any cloud services? Complementary question: It is obvious that the Desktop PC and the Laptop PC have different hardware configurations. How does the 'sync software' in question deal with video drivers, wlan drivers and their configurations? Note: I do not need all the PCs to be synced at the same time, because I work with only one single machine at once. Note: I considered to use Chef to solve the problem, but it seems that it might be really cumbersome to maintain such a setup. Note: I also considered using a bootable USB with Ubuntu installed (portable Linux), but I am not sure that the video drivers will work then.

  • ADF Essentials - Available for free and certified on GlassFish!

    - by delabassee
    If you are an Oracle customer, you are probably familiar with Oracle ADF (Application Development Framework). If you are not, ADF is, in a nutshell, a Java EE based framework that simplifies the development of enterprise applications. It is the development framework that was used, among other things, to build Oracle Fusion Applications. Oracle has just released ADF Essentials, a free to develop and deploy version of Oracle ADF's core technologies. As a good news never come alone, GlassFish 3.1.2 is now a certified container for ADF Essentials! ADF Essentials leverage core ADF features and includes: Oracle ADF Faces - a set of more than 150 JSF 2.0 rich components that simplify the creation of rich Web user interfaces (charting, data vizualization, advanced tables, drag and drop, touch gesture support, extensive windowing capabilities, etc.) Oracle ADF Controller - an extension of the JSF controller that helps build reusable process flows and provides the ability to create dynamic regions within Web pages. Oracle ADF Binding - an XML-based, meta-data abstraction layer to connect user interfaces to business services. Oracle ADF Business Components – a declaratively-configured layer that simplifies developing business services against relational databases by providing reusable components that implement common design patterns. ADF is a highly declarative framework, it has always had a very good tooling support. Visual development for Oracle ADF Essentials is provided in Oracle JDeveloper 11.1.2.3. Eclispe support is planned for a later OEPE (Oracle Enterprise Pack for Eclipse) release. Here are some relevant links to quickly learn on how to use ADF Essentials on GlassFish: Video : Oracle ADF Essentials Overview and Demo Deploying Oracle ADF Essentials Applications to Glassfish OTN : Oracle ADF Essentials Ressources

  • Error -12 hibernation image. Not enough free memory (sometimes)

    - by user99306
    I am having a problem with hibernation in Ubuntu 12.10, it had worked fine in 12.04. When I try and hibernate it sometimes appears to hibernate throws up an error and returns me to the desktop. The error I get is this: PM: Creating hibernation image: PM: Need to copy 375021 pages PM: Normal pages needed: 117957 + 1024, available pages: 110205 PM: Not enough free memory PM: Error -12 creating hibernation image Now I understand what the error means, but it doesn't make sense. My swap file is 5GB and is seldom ever used as I have 4GB of RAM. I know it is recommended to have 1.5 times more swap than RAM etc, but space doesn't seem to be the problem, despite the error. For example, I rarely use more than about 25%-30% of my RAM, yet still have the problem above. Moreover on a fresh boot and login, with no programs open and using only about 12% of RAM, I can get the above error - yet at other times I can hibernate whilst using 25% of my RAM. Also if I keep trying to hibernate, it eventually does after throwing up the above error four or five times. A successful hibernation looks like this: PM: Creating hibernation image: PM: Need to copy 295511 pages PM: Normal pages needed: 95534 + 1024, available pages: 132627 Is there some setting that I need to tweak or something I need to do before hibernating to avoid this problem? I guess the question could be better interpreted as: Is there some way of safely flushing the buffers and the cache before hibernation? Other than attempting to hibernate several times until it is successful! Thanks in advance.

  • Lock down PC so only a few programs can be used?

    - by user1413
    I'm interested in locking down my PC so that only a few programs can be used. For example, when I'm writing a paper I only want to be able to use Word. No Firefox or DVD player because I will be distracted. I want to have various modes (one for writing a paper, another for doing taxes) that will prevent me from using any program except for the ones I need to perform a task. Is there a program that will do that? Can be free or commercial.

  • java threads don't see shared boolean changes

    - by andymur
    Here the code class Aux implements Runnable { private Boolean isOn = false; private String statusMessage; private final Object lock; public Aux(String message, Object lock) { this.lock = lock; this.statusMessage = message; } @Override public void run() { for (;;) { synchronized (lock) { if (isOn && "left".equals(this.statusMessage)) { isOn = false; System.out.println(statusMessage); } else if (!isOn && "right".equals(this.statusMessage)) { isOn = true; System.out.println(statusMessage); } if ("left".equals(this.statusMessage)) { System.out.println("left " + isOn); } } } } } public class Question { public static void main(String [] args) { Object lock = new Object(); new Thread(new Aux("left", lock)).start(); new Thread(new Aux("right", lock)).start(); } } In this code I expect to see: left, right, left right and so on, but when Thread with "left" message changes isOn to false, Thread with "right" message don't see it and I get ("right true" and "left false" console messages), left thread don't get isOn in true, but right Thread can't change it cause it always see old isOn value (true). When i add volatile modifier to isOn nothing changes, but if I change isOn to some class with boolean field and change this field then threads are see changes and it works fine Thanks in advance.

  • How to enable iPhone auto lock during MPMoviePlayer playback?

    - by obiwahn
    When I play a video with MPMoviePlayerController in my app my iPhone does not auto lock (tested OS 3.0 & 3.1.2). However, the application.idleTimerDisabled = NO, so this setting is not affected by MPMoviePlayerController. How can I get my iPhone to sleep normally (e.g. after 3 min screen dims, then goes dark) when my app is running and playing a video?

  • Possible to lock attribute write access by Doors User?

    - by Philip Nguyen
    Is it possible to programmatically lock certain attributes based on the user? So certain attributes can be written to by User2 and certain attributes cannot be written to by User2. However, User1 may have write access to all attributes. What is the most efficient way of accomplishing this? I have to worry about not taking up too many computational resources, as I would like this to be able to work on quite large modules.

  • How can I lock the cursor to the inside of a window on Mac OS X?

    - by ZorbaTHut
    I'm trying to put together a game for Mac OS X which involves a lot of fast action and flinging around of the mouse cursor. If the user wants to play in windowed mode, I'd quite like to lock the cursor to the inside of the window to avoid accidentally changing programs in the heat of battle (obviously this will cancel itself if the user changes programs or hits escape for the pause menu.) On Windows, this can be accomplished easily with ClipCursor(). I can't find an equivalent on Mac OS X. Is there one?

  • When using emacs do you rebind caps-lock to CTRL?

    - by Wayne Werner
    This question is, as indicated, for those who use Emacs. When you do, do you rebind the caps-lock key to CTRL, or do you use the "normal" ctrl key? I've recently learned some Emacs commands and was using the Visual Studio 2008 emacs commands for a while, and of course I used a caps-rebind tool, but I'm curious how many other people do. On a side note, the emacs bindings for VS are severely incomplete :(
