  • How to provide i18n service for developer and end user

    - by user247245
    Many android applications have quite poor i18n-support, and for an understandable reason, as it adds much work for the developer. From a both intuitive and cultural point of view it would be a good thing if end-users could translate the apps themself, and OTA share the translation, without reinstalling the app itself. In concept; as wikipedia, some add content easily, others only use what's there. It's of course important that the service is as easy as possible to use, both for app-developers, and people willing to transcribe. To keep it simple, this is the solution I'm concidering; Developer perspective: Developer uses a customized setContentView when open activities/layouts that will seach for thanslations of xml-entries. (below) The customized version is provided as a free downloadable library/class..., turning the i18n feature to more or less a one liner. User perspective: User downloads app without any translation As app launches, it checks locale running at phone, and will look for a translated xml-file at shared space in SD. If no or old transcribed xml (above), try to download new from internet-service (ansync). This is all done by library above, no need for intents. Translator perspective: Separate app to provide translations for any app using the i18n service above. (Could be just a webapp), with some form of QA on translators/input. QUESTION: Now, for this to work efficiently, it has to be AeasyAP for the developer to even bother, and the most fluent solution would be a customized version of setContentView, that simply loads the translated values from external xml, instead of the ones in the apk. Is this possible at all, and if not, what's your suggested solutions? (And of course, Happy New Year, feliz ano novo, blwyddyn newydd dda, Gott Nytt År, kontan ane nouvo, szczesliwego nowego roku ...) Regards, /T

  • Hibernate: fetching multiple bags efficiently

    - by Jens Jansson
    Hi! I'm developing a multilingual application. For this reason many objects have in their name and description fields collections of something I call LocalizedStrings instead of plain strings. Every LocalizedString is basically a pair of a locale and a string localized to that locale. Let's take an example an entity, let's say a book -object. public class Book{ @OneToMany private List<LocalizedString> names; @OneToMany private List<LocalizedString> description; //and so on... } When a user asks for a list of books, it does a query to get all the books, fetches the name and description of every book in the locale the user has selected to run the app in, and displays it back to the user. This works but it is a major performance issue. For the moment hibernate makes one query to fetch all the books, and after that it goes through every single object and asks hibernate for the localized strings for that specific object, resulting in a "n+1 select problem". Fetching a list of 50 entities produces about 6000 rows of sql commands in my server log. I tried making the collections eager but that lead me to the "cannot simultaneously fetch multiple bags"-issue. Then I tried setting the fetch strategy on the collections to subselect, hoping that it would do one query for all books, and after that do one query that fetches all LocalizedStrings for all the books. Subselects didn't work in this case how i would have hoped and it basically just did exactly the same as my first case. I'm starting to run out of ideas on how to optimize this. So in short, what fetching strategy alternatives are there when you are fetching a collection and every element in that collection has one or multiple collections in itself, which has to be fetch simultaneously.

  • Calling and consuming a JBoss Web Service from JavaScript (AJAX)

    - by Andreas Grech
    I am fiddling around with JBOSS's Web Services, and I have created the following: http://127.0.0.1:8080/IM/TestService?wsdl Now I need to access Web Methods from that Web Service from JavaScript. Say I have a web method named foo in TestService, how do I make an ajax call to it? I tried accessing the method via http://127.0.0.1:8080/IM/TestService/foo, but I'm getting an HTTP Status 404.

  • Is there a way to wrap some local cache around a URLConnection

    - by Michael Neale
    I am using a URLConnection class - I want to be able to grab a stream to a given URL even if said URL is unavailable (ie cache the last known cope of the content on a URL, to some local file system dir) - now I have written this code a few times (never happy with it) and was wondering if there is something better out there that might be able to do this.

  • How do I prevent use of beta classes from google guava library?

    - by mjlee
    We have been using Google collections in the production for several months. We would like to start using guava for additional functions. However, I'm afraid to bring guava into our product stack b/c some developers may start to use 'beta' classes. We have various unit-tests in our code but at this point, I prefer not to include 'beta' class b/c it is subject to change in the future. Is there any easy way to do detect if the project includes any 'beta' guava classes?

    Suppose I have the following class. public class gen<T> { public gen(){ } Class<T> class(){ //something that figures out what T is. } } How can I implement the class() function without pass any additional information? What I did is here, but I have to pass a object of T into the object gen. public class gen<T> { public gen(){ } Class<T> class(T var){ return (Class<T>) var.getClass(); } }

  • How do I insert this subclass into my code?

    - by BamsBamx
    This is a very noob question so I hope you can help me with this... This is my built code: public class PantallaOpciones extends PreferenceActivity { private SharedPreferences preferences; @Override public void onCreate(Bundle savedInstanceState) { preferences = PreferenceManager.getDefaultSharedPreferences(this); findPreference("speechkeycode").setOnPreferenceClickListener(keycodedialog); Preference.OnPreferenceClickListener keycodedialog = new Preference.OnPreferenceClickListener(){ public boolean onPreferenceClick(Preference preference){ keycodedialog(); return false; }}; } private void keycodedialog(){ final Dialog dialog = new Dialog(this); dialog.setContentView(R.layout.keycodedialog); dialog.setTitle("Speech keycode"); final TextView keypresstext = (TextView) findViewById(R.id.keypresstext); Button savekeycode = (Button) dialog.findViewById(R.id.btnsavekeycode); savekeycode.setOnClickListener(new OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); Button resetkeycode = (Button) dialog.findViewById(R.id.btnresetvalue); resetkeycode.setOnClickListener(new OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); dialog.show(); } Okay, now I want to add this code to dialog: public boolean onKeyDown(int keyCode, KeyEvent event) { //SOME STUFF return super.onKeyDown(keyCode, event); } So I want to listen to a keypress when dialog is opened and show the keycode of hardware press by using textview.settext()... The question is: how do I insert public boolean onKeyDown into the dialog??? Thanks in advance!! :)

  • any way to use ajax with jstl customtags without duplicating tags in javascript?

    - by CodeMonkeyB
    I am working on a page where part of the content is loaded normally and the pages are rendered using jsps. The product images and links generated on that page are by custom jstl tags. When the user scrolls more products are requested from the server in a JSON response and then using UnderscoreJS templates they are rendered and added to the bottom of the page. Is there any way I can use the JSTL tags in Javascript without recreating them using a javascript function (it won't be possible to re-create all of them in javascript). What is the best way to handle this scenario? I guess I could return a rendered html response for the ajax call, but that would mean I have some ajax requests which use json and some that use rendered html...

  • Creating a fancy search bar with Swing components

    - by Kavon Farvardin
    I'm trying to come up with an elegant recreation of the search bar component in Thunderbird. The clear button doesn't appear until there is text in the box, so that screen-shot is a bit inaccurate. Should I use a layered pane and get some buttons to float above the box? (but then getting the text to not appear below the buttons would be hacky) Maybe just put buttons at the ends of the search bar and have it somehow blend in? Any ideas or maybe a style reconsideration is welcome, thank you.

  • Why isn't the @Deprecated annotation triggering a compiler warning about a method?

    - by Scooter
    I am trying to use the @Deprecated annotation. The @Deprecated documentation says that: "Compilers warn when a deprecated program element is used or overridden in non-deprecated code". I would think this should trigger it, but it did not. javac version 1.7.0_09 and compiled using and not using -Xlint and -deprecation. public class test_annotations { public static void main(String[] args) { test_annotations theApp = new test_annotations(); theApp.this_is_deprecated(); } @Deprecated public void this_is_deprecated() { System.out.println("doing it the old way"); } }

  • How can I make a workspace-folder level build script visible in the Eclipse Project Explorer?

    - by Chris
    I have a number of interdependent projects in an Eclipse workspace. Eclipse manages dependencies between them within the IDE but I'm starting work on a master build script that will sit in the folder about all the projects (the workspace folder). I haven't decided on if I will use Maven, Gradle or Ant/Ivy tet, but my question is, is there a way so that I can see a build script in the workspace folder in the Project/Package explorer? Currently it only shows me projects, but assuming I decide on an Ant build, I want to be able to see the main build.xml file in this window. I've played around with settings to no avail. Is it possible? If not, should I just set up an external run configuration instead?

  • Triggering Quartz job from JSF (Any front end)- How to wait for the job execution to be over

    - by Maximus
    I am developing a front end to trigger a quartz job on the fly. I have a form in the JSF page whose click action will dynamically trigger a quartz job. The job is invoked by the following statement, the job is triggered and everything works fine. scheduler.triggerJob("Job1",Scheduler.DEFAULT_GROUP,jobDataMap); From what I understand the job seems to run in a separate thread and the execution of the calling function does not wait for the job to be over. Since I am invoking the job from front end, I would like to wait till the job is over before I navigate to a different JSF page. So I can display an error message if the job fails. I would also like to display a message to the user, "Processing job, please wait.." until the job is actually over. Any ideas on how to accomplish this will be appreciated. Thanks !

  • Is it possible to apply inheritance to a Singleton class?

    - by Bragaadeesh
    Hi, Today I faced one question in interview. Is it possible to apply inheritance concept on Singleton Classes. I said since the constructor is private, we cannot extend that Singleton class (can someone please validate this). Next thing he asked me is to apply inheritance on that Singleton class. So, I made the Singleton's constructor as protected thinking that child's constructor also has be protected. But I was wrong the child can have a modifier either equal to or higher than that. So, I asked him to give a real world example on such a case. He was not able to give me one and said that I cant ask questions and wanted me to tell whether this scenario is possible or not. I went kind of blank. My question here is, Is this possible? Even if its possible, what is the use of it? What real world scenario would demand such a use. Thanks
