  • GWT now has spring roo support, what will this mean to GWT developers?

    - by Mark M
    I have been using GWT with App Engine for a while now. Recently there was an announcement that GWT will support Spring Roo and SpringSource Tool Suite (http://googlewebtoolkit.blogspot.com/2010/05/gwt-21-milestone-1-is-now-available.html). I am having trouble seeing the big picture from the Google announcement page. For those without much knowledge of Spring what does this mean for GWT developers used to building swing-like gui's?

  • iPhone app rejected because of Beta word is used

    - by arielcamus
    Hi, I was using the text "We are currently on Beta. Please, enter our website and ask for an invitation" when a user click on "Register" on our app. However, Apple has rejected our app because it can not has any disabled featured and can not contains word "Beta". What would you do in this situation? I don't know if hide this option and show it only when an API call response says "registerEnabled = YES" or just change the text and use: "You need and invitation to access OUR_APP. Visit our website to get one." Except for registering, our app is fully functional. Thank you, A

  • How to open different App version for one given file extension

    - by Erik Lenaerts
    We have a data files with an extension ".ppx" for our business app here. Users will typically have multiple versions of the application installed (side by side) for example version 1 and version 2. The ppx files are xml files and they contain the version of the app they were created from (v1 or v2). Lets say that we have AFileCreatedWithAppv1.ppx and AFileCreatedWithAppv2.ppx opens with version 1 or version 2 of our app respectivly when they both have the same file extension? It must be doable since that is what Visual Studio does. In fact, they even provide different icons for the same .sln extension to indicate what Visual Studio version it will open with. I learned that Visual Studio is using the Selector or Launcher in between, but then again, how do they change the icons in Windows? cheers :)

  • iPhone tethering app source

    - by jamone
    I know there are a few apps that allow a jail broken iPhone to tether over WiFi to a computer so the computer can use the iPhone's 3G. What I want to know is if anyone knows of any open source apps that do this, or partial code to handle the majority of this that I could make in to a minimal app? I don't want to jail break since I do official development, but would like to be able to compile and sideload an app on my personal phone to do this. Even without jail broken privileges an app could use an existing wifi connection (adhoc created by the computer) to share its 3G.

  • Replacing Resource files on new BlackBerry app version

    - by Jeff
    Hello, I am maintaining an existing BlackBerry application (implemented as a MIDlet). The application contains a number of data files that get bundled with the app as resources. Some of these data files need to be updated for a new version of the app. When the user goes to install a new version of the application (via URL of Jad file), it prompts them with the following message "Persistent data exists for the application. Would you like to retain this data? " If the user selects "Yes", it looks like the app continues to use the old resource files. This is so surprising to me. First of all, am I losing my mind or will an upgrade really not overwrite existing resource files? Is there any way I can force it to? Thanks, Jeff

  • BIRT Viewer with Rails App

    - by anoojrajan
    Has anyone tried using BIRT for reporting on a Rails app.. I am working on a pretty big app on ROR. I was trying to get BIRT to work happily with the app. Since the BIRT Report Designer cannot be used with Rails, I decided to use BIRT Viewer alone and give the links to the reports on the page and have BIRT Viewer running on Tomcat on the same box to render the reports. This has a big problem of not being able to allow the user to create any custom reports. Has anybody tried anything even remotely close to this??? If yes do you have any tips for me on any part of this endeavor? Thanks in advance for all the help.

  • Looking to eventually build a smartphone app...

    - by Brian L
    Hi all- I'm a young, inexperienced programmer (I've had a year of Java, some MATLAB, and HTML/CSS in school) but I've decided that to get better, I'm making it my goal to produce a simple smartphone app of some kind this year- probably either webOS or Android since I'm on a PC and can't afford a Mac just to write an iPhone app. So my question is, where do I start? I've read the threads about How to Write for Android and such, but I'm not sure I have enough Java experience to just jump right in. And then there's webOS which is based on JavaScript, correct? I guess I'd just like some input from more experienced folks. I have some Barnes and Noble book credit I'm looking to get rid of too, so if there's a guide you think would be useful, feel free to request. tl;dr: Programming newbie ultimately wants to build a simple smartphone app. Where do I start?

  • Creating your own UTI for an iOS app.

    - by Kalle
    Hello all, The app I'm developing has a custom file format for its files, and I'd like to be able to use the "Open In ..." feature of iOS which lets users e.g. email each other a file and then open it directly in the app. I've gotten as far as adding the CFBundleDocumentType stuff in the Info.plist file, but the problem is the LSItemContentTypes. From what I've read, I need to provide the actual file as a UTI, rather than just saying ".myfileextension", and I can't find a lot about how to create UTI's in a iOS app. Anyone know?

  • errors with gae-sessions and nose

    - by Kekito
    I'm running into a few problems with adding gae-sessions to a relatively mature GAE app. I followed the readme carefully and also looked at the demo. First, just adding the gaesesions directory to my app causes the following error when running tests with nose and nose-gae: Exception ImportError: 'No module named threading' in <bound method local.__del__ of <_threading_local.local object at 0x103e10628>> ignored All the tests run fine so not a big problem but suggests that something isn't right. Next, if I add the following two lines of code: from gaesessions import get_current_session session = get_current_session() I get the following error: Traceback (most recent call last): File "/Users/.../unit_tests.py", line 1421, in testParseFBRequest data = tasks.parse_fb_request(sr) File "/Users/.../tasks.py", line 220, in parse_fb_request session = get_current_session() File "/Users/.../gaesessions/__init__.py", line 36, in get_current_session return _tls.current_session File "/Library/.../python2.7/_threading_local.py", line 193, in __getattribute__ return object.__getattribute__(self, name) AttributeError: 'local' object has no attribute 'current_session' Any suggestions on fixing the above would be greatly appreciated.

  • Linker Error: iPhone Unit Test Bundle referencing App classes

    - by ohhorob
    Starting with an app already in development, I have carried out the instructions in the iPhone Development Guide – Unit Testing Applications I can successfully include and use my App's classes in Application-style tests that run on the device, and output their results to the console. If I add the following line of code: STAssertTrue([viewController isKindOfClass:[LoginViewController class]], @"Top view controller is not LoginViewController"); The following build error is generated: Undefined symbols: "_OBJC_CLASS_$_LoginViewController", referenced from: __objc_classrefs__DATA@0 in LoginViewTest.o ld: symbol(s) not found collect2: ld returned 1 exit status I can provide more configuration information for the project and the Testing target, but the setup works file without the [LoginViewController class] line in the test source. Without that line, I can reference the class, use it's properties and send it messages successfully. Is there a linking build setting, or bundle loading option that is required when attempting to use an App class in this fashion? Or should I find another type of test to confirm that the class of an object is the expected one?

  • Is a JID a user identifier as well as an application address?

    - by zxc
    In the App Engine docs, a JID is defined like this: An application can send and receive messages using several kinds of addresses, or "JIDs." On Wikipedia, however, a JID is defined like this: Every user on the (XMPP) network has a unique Jabber ID (usually abbreviated as JID). So, a JID is both a user identifier and an application address?

  • Lookig for "GAE-TaskQueues" in Asp.net

    - by Fabrizio
    I normally works in asp.net. But recently I was testing Google App Engine and I found TaskQueues: it's very interesting and powerful. Does anyone know a similar service for asp.net? I know MSQueue but it's not what I need. I need something like GAE TaskQueue: I put an URL in queue and the URL is triggered (based on queue config).

  • How do you validate a URL with a regular expression in Python?

    - by Zachary Spencer
    I'm building a Google App Engine app, and I have a class to represent an RSS Feed. I have a method called setUrl which is part of the feed class. It accepts a url as an input. I'm trying to use the re python module to validate off of the RFC 3986 Reg-ex (http://www.ietf.org/rfc/rfc3986.txt) Below is a snipped which should work, right? I'm incredibly new to Python and have been beating my head against this for the past 3 days. p = re.compile('^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?') m = p.match(url) if m: self.url = url return url

  • press button to open web page from app

    - by Lee
    I have an app that I want to interact with a web page. Basically I want to press a button and the web page will open in a new view... Sorry I wasn't clear, I am developing on a Mac for an iPhone. Currently I have a "locate me" app that displays your Latitude and Longitude. I want to use those variables to populate 2 of the blanks on a PHP web page/form I have developed. I have added a label and button to my current app, when the button is pressed the URL with the Lat and Long (as passed vars) are displayed in the label. I want those vars to appear on my web page. Hope this is clearer... Solved: I just added these lines of code I found here: NSURL *url = [ [ NSURL alloc ] initWithString: @"http://www.cnn.com" ]; [[UIApplication sharedApplication] openURL:url];

  • iOS 5 - Coredata Sqlite DB losing data after killing app

    - by Brian Boyle
    I'm using coredata with a sqlite DB to persist data in my app. However, each time I kill my app I lose any data that was saved in the DB. I'm pretty sure its because the .sqlite file for my DB is just being replaced by a fresh one each time my app starts, but I can't seem to find any code that will just use the existing one thats there. It would be great if anyone could point me towards some code that could handle this for me. Cheers B - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (__persistentStoreCoordinator != nil) { return __persistentStoreCoordinator; } NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil]; NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"FlickrCoreData.sqlite"]; NSError *error = nil; __persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; if (![__persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } return __persistentStoreCoordinator; }
