• Android application listed as compatible with Sony Xperia S but still filtered from google play

  - by mlidal

  I have published an Android application and some users are complaining that it is listed as not compatible with Sony Xperia S. According to the developer console Xperia S (LT26i) is listed as compatible. Do anyone know of any reason why the app is still filtered from google play? I have seen people reporting problems with big apk files. This app is about 20Mb in size, with the largest file being 14Mb. Quite a bit but not enough to cause problems I think... Here is the output from aapt dump badging: package: name='no.bouvet.nrkut' versionCode='4' versionName='1.0' sdkVersion:'4' targetSdkVersion:'13' uses-permission:'android.permission.ACCESS_FINE_LOCATION' uses-permission:'android.permission.ACCESS_COARSE_LOCATION' uses-permission:'android.permission.ACCESS_WIFI_STATE' uses-permission:'android.permission.ACCESS_NETWORK_STATE' uses-permission:'android.permission.INTERNET' uses-permission:'android.permission.WRITE_EXTERNAL_STORAGE' application-label:'UT.no' application-icon-120:'res/drawable-ldpi/utno_launcher.png' application-icon-160:'res/drawable-mdpi/utno_launcher.png' application-icon-240:'res/drawable-hdpi/utno_launcher.png' application-icon-320:'res/drawable-xhdpi/utno_launcher.png' application: label='UT.no' icon='res/drawable-mdpi/utno_launcher.png' launchable-activity: name='no.bouvet.nrkut.MainActivity' label='UT.no' icon='' uses-feature:'android.hardware.location' uses-feature:'android.hardware.location.gps' uses-feature:'android.hardware.location.network' uses-feature:'android.hardware.wifi' uses-feature:'android.hardware.touchscreen' uses-feature:'android.hardware.screen.portrait' main other-activities search supports-screens: 'small' 'normal' 'large' 'xlarge' supports-any-density: 'true' locales: '--_--' densities: '120' '160' '240' '320'

• iPhone Adding Controls (UIButton, UILabel etc.) on a Playing Video!

  - by Taimur Hamza

  I have been assigned an 'easy' task of adding a button over a playing video. I m terming it easy as i have got the sample code downloaded from Apple's sample code. http://rapidshare.com/files/393248642/MoviePlayer_iPhone.zip Anybody who wants to reply to my query and intends to help should download this project and run it otherwise it wudnt be easy to understand my problem. Thanks! And now the weird problem i am facing is: In the sample project developer has added the view ( UILabel and UIButton ) in the Appdelegate. And i want it other xib files not the App delegate . Fine i added a view 'myButtonABC' instead of 'My Overlay View'. And added this code in my xib file's implementation file. (void)viewDidLoad { TaimurAppDelegate *appDelegate = (TaimurAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate initAndPlayMovie:[self localMovieURL]]; NSArray *windows = [[UIApplication sharedApplication] windows]; if ([windows count] 1) { UIWindow *moviePlayerWindow = [[UIApplication sharedApplication] keyWindow]; [moviePlayerWindow addSubview:self.myABC]; } } Now my question is do i need to declare a UIWindow object in the header file here. As i am not working in the app delegate class. As i said previously i have to add this button over a video in other screen and not on the main screen. The third question is can anyone, which in fact is the most imp of all. In my view , if i am able to do this one my problem would be solved. As i have spend considerable amount of time on this task so far. The question is " How can i connect myABCButton (which is a view added to my xib file ) to the File's Owner. Thanks for your patience. Replies Appreciated ! Taimur

• Design issue in Iphone Dev - Generic implementation for Game Bonuses

  - by Idan

  So, I thought consulting you guys about my design, cause I sense there might be a better way of doing it. I need to implement game bonuses mechanism in my app. Currently there are 9 bonuses available, each one is based of different param of the MainGame Object. What I had in mind was at app startup to initialize 9 objects of GameBonus while each one will have different SEL (shouldBonus) which will be responsible for checking if the bonus is valid. So, every end of game I will just run over the bonuses array and call the isBonusValid() function with the MainGame object(which is different after every game). How's that sound ? The only issue I have currently, is that I need to make sure that if some bonuses are accepted some other won't (inner stuff)... any advice how to do that and still maintain generic implementation ? @interface GameBonus : NSObject { int bonusId; NSString* name; NSString* description; UIImage* img; SEL shouldBonus; } @implementation GameBonus -(BOOL) isBonusValid(MainGame*)mainGame { [self shouldBonus:mainGame]; } @end

• How do I send text to a UITextView?

  - by Lee

  I'm new to iphone development. I'm a VB programmer who is trying to convert a VB application to an ipad app. I need some help with sending text to a UITextView. I want to first have a UIPickerView and then once the user hits a UIButton, a UITextView appears and the text is then generated by my source code code, line by line. The code would constantly be concatenating strings to the text. It would sort of go like this-- 1) User makes selections with UIPickerView. 2) User then hits UIButton. 3) UIPickerView is replaced on the screen with a UITextView. 4) The code does stuff. 5) The code adds the 1st line of text into the UITextView. 6) The code does more stuff. 7) The code then adds the 2nd line of text into the UITextView, retaining the 1st line that was already there. Steps 6 and 7 are repeated until the code is done. Does anyone know of any examples of this that I could look at? I am mostly interested in finding something like a youtube video, a webpage that explains the code or even a good book that covers this particular topic. I am finding that the sample codes that Apple has on this site goes over my head. In fact, I could probably benefit from a good book. But, I am looking for one that I would already know covers this particular topic, since it is so essential to the app that I am trying to build.

• Django does not load internal .css files

  I have created a Django project in local which runs without any kind of problem.

• uiview's controls unresponsive.. or how to foul up a view hierarchy

  - by user293139

  Hello all, I'm working on an app that has two sections, a config section and a results section. My config section needs to be 2 separate views (horizontal and vert, and yes, I can hear the intake of breath from here), with one rotatable view for the results. b/c of layout restraints and a lot of pain around rotation, I'm not using a navigation controller. I've been experiencing the joys of rotation experimentation and have settled upon keeping my views contained as subviews of my view controller. i.e. view controller.view.subviews = configH, configV, and results. I then use the controller.view bringSubviewToFront to bring the either the configH, configV, or the result view to the front. Rotation works-queue(humor intended) the angelic choirs... almost. What's happening is that my configV button's are responsive, but when the device (or simulator) is rotated, my configH controls are not. (configV is the second subview added, but the first one to be brought to the front because app comes up in portrait mode) The controls on the results view also work. Plan B was to assign the controller.view to configH, configV, or results. All of my controls now work, but rotation is now fouled up. Question 1: Is there a better way to do this? (a horizontal and vertical config view and a rotatable results view) Question 2: Does the above suggest a design issue, or is it more likely that my addled brain is just missing something in my own code. (nothing from the peanut gallery please) many thanks!

• Problems running XNA game on 64-bit Windows 7

  - by Tesserex

  I'm having problems getting my game engine to run on my brother's machine, which is running 64-bit Windows 7. I'm developing on 32-bit XP SP2. My app uses XNA, FMOD.NET, and another dll I wrote entirely in C#. Everything is targeted to x86, not AnyCPU. I've read that this is required for XNA to work because there is no 64-bit xna framework. I recompiled FMOD.NET as x86 as well and made sure to be using the 32-bit version of the native dll. So I don't see any problems there. However when he tries to run my app, it gives an error which is mysterious, but not unheard of. A FileNotFoundException with an empty file name, and the top of the stack trace is in my main form constructor. The message is The specified module could not be found. (Exception from HRESULT: 0x8007007E) I found some threads online about this error, all with very vague, mixed, and fuzzy responses that don't really help me. Most remind people to target x86. Some say check that they have all the dlls necessary. I gave my brother Microsoft.Xna.Framework.dll, but does he need to install the entire XNA redistributable package? When I take everything I sent him and stick it in a random directory, it still runs fine for me. I developed the game in VS2008, not in game studio, using XNA 3.0 and a Windows Forms control that uses XNA drawing which I found in an msdn tutorial. I would also like to avoid requiring a full installer if possible. Any insight? Please?

• Extend the bootstrap-typeahead in order to take an object instead of a string

• Why Android for enterprise applications?

  - by mcabral

  Recently one of our clients is considering the posibility of picking up an old WinMobile 5.0 project. Several features are to be added to the point it will be a major version update. The client is worried about the mobile market, and thinks there's a chance all the effort put in this development will have to be thrown away in a couple of year due to the dinamics of the mobile market and the deprecation of mobile devices. So, the client is not sure whether he should continue with Windows Mobile (changing from WM 5.0 to 6.X) or starting from scratch with another technology. From our part we have been studing the mobile market, looking for clues for which will be the winning horse. The safe move seems to continue with WM just because re writing an entire application from scratch involves more risks and delays. On the other hand WM seems to be losing market and the ghost of an exit on their part is growing stronger everyday. But what can be say about Android? Everyone is talking about it and is growing at full speed but what avantagies will it bring to the table? Why should we start a fresh applicaction on this technology? So the question remains the same.. is Andriod mature enough for an enterprise application? Will you recomend it to one of your clients? Will you port/rewrite a WM application to Andriod? What's the trade-off? EDIT: Addressing commentaries. The app is entirely built with C# and Compact Framework. The app is for logistics/management.

• Is there a limit for the number of files in a directory on an SD card?

  - by jamesh

  I have a project written for Android devices. It generates a large number of files, each day. These are all text files and images. The app uses a database to reference these files. The app is supposed to clear up these files after a little use (perhaps after a few days), but this process may or may not be working. This is not the subject of this question. Due to a historic accident, the organization of the files are somewhat naive: everything is in the same directory; a .hidden directory which contains a zero byte .nomedia file to prevent the MediaScanner indexing it. Today, I am seeing an error reported: java.io.IOException: Cannot create: /sdcard/.hidden/file-4200.html at java.io.File.createNewFile(File.java:1263) Regarding the sdcard, I see it has plenty of storage left, but counting $ cd /Volumes/NO_NAME/.hidden $ ls | wc -w 9058 Deleting a number of files seems to have allowed the file creation for today to proceed. Regrettably, I did not try touching a new file to try and reproduce the error on a commandline; I also deleted several hundred files rather than a handful. However, my question is: are there hard limits on filesize or number of files in a directory? am I even on the right track here? Nota Bene: The SD card is as-is - i.e. I haven't formatted it, so I would guess it would be a FAT-* format. The FAT-32 format has hard limits of filesize of 2GB (well above the filesizes I am dealing with) and a limit of number of files in the root directory. I am definitely not writing files in the root directory.

• How do I add two alternating UITableViews to an existing UINavigationController view?

  - by Ron Flax

  I'm new to iPhone development and I am writing an iPhone app that needs two different table views, which are selectable using a button bar or tab bar. These table views are both the same size, but only cover about two thirds of the screen from the bottom up. The top portion of the screen remains the same when either of these tables is displayed. I'd also like to animate (flip) these views when the user selects one or the other. The view that these two tables will be displayed on is the detail view of my app where the user has already selected an item from the primary screen's table. I'm using a UINavigationController to manage the primary and detail views and I have this working. I also have the first of these two detail tables working as part of my detail view, but I think it makes more sense to isolate the code for these two tables and not duplicate all of the code for the part of the detail view that doesn't change. I don't really care how these two table views are created (either in code or via IB). I've tried several things and I can't seem to figure it out. Any help or ideas (with sample code) would be greatly appreciated!

• Customers angry, fighting unknown DLL dependencies

  - by wheaties

  I'm a one man show developing a C++ Windows application for a customer. Over the past several months we've been running to the same problems with missing DLL dependencies on customer machines. Despite my best efforts something keeps going wrong and we get angry emails back. My boss and my boss's boss are angry with me and the customers aren't happy. I'm hoping you guys can help out and give suggestions/ideas on how to get the deliverables in order. Before some of the obvious: I have no test machine. That is, I can't replicate the customer environment nor attempt to install the app on a "clean" system to catch gotchas before shipping. I've tried using depends.exe to track down what versions of the DLLs my project is dependent upon. I'm shipping our code with the redistributables I've been able to find that way. After that it's an angry customer email waiting game. I'm required to use a third-party DLL which can not be registered (it's buggy as hell.) I'm not supposed to use Install Shield, any other automated installer, or write an install script. I provide written instructions on how to get the app installed (unzip, double click exe file.) I'm tired of taking heat for this stuff. What am I missing that I could be doing? What should I ask in terms of support from my employer? How should I ask for that support in a way that they'll provide it?

• Weird Qt SSL issue -- error "No Error" shows up, nothing else, and if I ignore it, everything works

  - by houbysoft

  The issue is as follows : in my Qt app, I have a QWebView, which I use to load a HTTPS page. Everything worked fine on my development machine, so I'm now trying to get it to run on a test machine. I ran the app, but the page didn't load (the QWebView was blank). After much debugging, I found the problem is that an SSL error shows up, and the sslErrors() signal is fired. Here is my sslErrors() handling code: void blah::sslErrors(QNetworkReply *reply, const QList<QSslError> &errors) { foreach(QSslError error, errors) { qDebug() << error.errorString() << endl; } reply->ignoreSslErrors(); } The only thing the above code prints is: "No error" So there's no error, but unless I call reply->ignoreSslErrors(), the page doesn't load (on the test machine, on my developer computer no error is reported). Huh? Is this a bug? Is it safe to ignore the error, if I make sure it's of the type "No error"?

• CLLocationManager class method not calling in iPodTouch

  HI all, I was using a sample code which uses CLLocationManager class to determine the current location of user. when i run this app on iPad i am getting the correct location but when i run the same app on iPod Touch i am getting a blank label i.e nothing is displayed on the label .although wi-fi signal strength is good in both iPod and iPad.The code looks like... - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{ int degrees = newLocation.coordinate.latitude; double decimal = fabs(newLocation.coordinate.latitude - degrees); int minutes = decimal * 60; double seconds = decimal * 3600 - minutes * 60; NSString *lat = [NSString stringWithFormat:@"%d° %d' %1.4f\"", degrees, minutes, seconds]; latLabel.text = lat; [latLocationArray addObject:lat]; degrees = newLocation.coordinate.longitude; decimal = fabs(newLocation.coordinate.longitude - degrees); minutes = decimal * 60; seconds = decimal * 3600 - minutes * 60; NSString *longt = [NSString stringWithFormat:@"%d° %d' %1.4f\"", degrees, minutes, seconds]; longLabel.text = longt; [longLocationArray addObject:longt]; }

• Occasional weird Glassfish errors, resolved by a restart?

  - by Pooria

  I'm developing a web app using netbeans with GlassFishv3. Every once in a while when I add a new feature in my app, glassfish starts nagging with stupid errors, after a lot of time wasting and panicking, i restart glassfish and run my application again, then suddenly the errors all go away and my site starts acting correctly. (or in case I have made a real mistake, i receive a reasonable & descriptive error from GF.) [Edit: the rest of the question was revealed to have been my own mistake.] But the problems don't end there. Recently, i added the ability to write comments in a (JSF) page, after the user submits their comment, i add it to the database and redirect to the same page, so that hopefully the page refreshes with the new comment, but it wont! The underlying Mysql database shows that the new comment has been added, but the page just wont show the new comment! I've tried everything (e.g. deleting browser cache, using different browsers) but only after restarting GF is when the page shows the new comment! Do you have any idea what the problem could be? Could this be a Glassfish bug? What i am using: JSF2, EJB3.1, JPA, MySql

• EOFException in ObjectInputStream thrown accessing Servlet. Only for Webstart ?!

  - by Houtman

  Hi, My app. is started from both the commandline and by using an JNLP file. Im running java version 1.6.0_14 First i had the problem that i created the Buffered input and output streams in incorrect order. Found the solution here at StackOverflow . So starting from the commandline works fine now. But when starting the app using Webstart, it ends here java.io.EOFException at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source) at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown Source) at java.io.ObjectInputStream.readStreamHeader(Unknown Source) at java.io.ObjectInputStream.<init>(Unknown Source) at <..>remoting.thinclient.RemoteSocketChannel.<init>(RemoteSocketChannel.java:76) I found some posts regarding similar problems; at bugs.sun.com - identifies problem as solved in 6u10(b12)? at ibm.com - identifies cookies problem The latter suggests that there is a problem in Webstart with cookies. It doesn't seem to be acknowledged as a proper java bug though.. Still i am a bit lost in the solution provided regarding the cookies. Can anyone expand on the cookie solution? Many thanks.

• NSUserDefaults: Saved Number Always 0, iPhone

  - by Stumf

  Hello all, I have looked at other answers and the docs. Maybe I am missing something, or maybe I have another issue. I am trying to save a number on exiting the app, and then when the app is loaded I want to check if this value exists and take action accordingly. This is what I have tried: To save on exiting: - (void)applicationWillTerminate: (UIApplication *) application { double save = [label.text doubleValue]; [[NSUserDefaults standardUserDefaults] setDouble: save forKey: @"savedNumber"]; [[NSUserDefaults standardUserDefaults] synchronize]; } To check: - (IBAction)buttonclickSkip{ double save = [[NSUserDefaults standardUserDefaults] doubleForKey: @"savedNumber"]; if (save == 0) { [self performSelector:@selector(displayAlert) withObject:nil]; test.enabled = YES; test.alpha = 1.0; skip.enabled = NO; skip.alpha = 0.0; } else { label.text = [NSString stringWithFormat:@"%.1f %%", save]; } } The problem is I always get my alert message displayed, the saved value is not put into the label so somehow == 0 is always true. If it makes any difference I am testing this on the iPhone simulator. Many thanks, Stu

• The uncatchable exception, pt 2

  - by chaiguy

  Ok I've done some testing and I've reduced the problem to something very simple: i. Create a method in a new class that throws an exception: public class Class1 { public void CallMe() { string blah = null; blah.ToLower(); } } ii. Create a MethodInfo that points to this method somewhere else: Type class1 = typeof( Class1 ); Class1 obj = new Class1(); MethodInfo method = class1.GetMethod( "CallMe" ); iii. Wrap a call to Invoke() in a try/catch block: try { method.Invoke( obj, null ); // exception is not being caught! } catch { } iv. Run the program without the debugger (works fine). v. Now run the program with the debugger. The debugger will halt the program when the exception occurs, even though it's wrapped in a catch handler that tries to ignore it. (Even if you put a breakpoint in the catch block it will halt before it reaches it!) In fact, the exception is happening when you run it without the debugger too. In a simple test project it's getting ignored at some other level, but if your app has any kind of global exception handling, it will get triggered there as well. This is causing me a real headache because it keeps triggering my app's crash-handler, not to mention the pain it is to attempt to debug.

• CakePHP: Missing database table

  - by Justin

  I have a CakePHP application that is running fine locally. I uploaded it to a production server and the first page that uses a database connection gives the "Missing Database Table" error. When I look at the controller dump, it's complaining about the first table. I've tried a variety of things to fix this problem, with no luck: I've confirmed that at the command line I can login with the given MySQL credentials in database.php I've confirmed this table exists I've tried using the MySQL root credentials (temporarily) to see if the problem lies with permissions of the user. The same error appeared. My debug level is currently set to 3 I've deleted the entire contents of /app/tmp/cache I've set 777 permissions on /app/tmp* I've confirmed that I can run DESCRIBE commands at the commant line MySQL when logged in with the MySQL credentials used by by the application I've verified that the CakePHP log file only contains the error I'm setting in the browser window. I've tried all the suggestions I could find in similar postings on SO I've Googled around and didn't find any other ideas I think I've eliminating the obvious problems and my research isn't turning anything up. I feel like I'm missing something obvious. Any ideas?

• ListCtrl - wxPython / Python

  - by Francisco Aleixo

  Hello everyone. My question is if we can assign/bind some value to a certain item and hide that value(or if we can do the same thing in another way). Example: Lets say the columns on ListCtrl are "Name" and "Description": self.lc = wx.ListCtrl(self, -1, style=wx.LC_REPORT) self.lc.InsertColumn(0, 'Name') self.lc.InsertColumn(1, 'Description') And when I add a item I want them to show the Name parameter and the description: num_items = self.lc.GetItemCount() self.lc.InsertStringItem(num_items, "Randomname") self.lc.SetStringItem(num_items, 1, "Some description here") Now what I want to do is basically assign something to that item that is not shown so I can access later on the app. So I would like to add something that is not shown on the app but is on the item value like: hiddendescription = "Somerandomthing" Still didn't undestand? Well lets say I add a button to add a item with some other TextCtrls to set the parameters and the TextCtrls parameters are: "Name" "Description" "Hiddendescription" So then the user fills this textctrls out and clicks the button to create the item, and I basically want only to show the Name and Description and hide the "HiddenDescription" but to do it so I can use it later. Sorry for explaining more than 1 time on this post but I want to make sure you understand what I pretend to do.

• Why does a simple ApplicationSetting PropertyBinding for a Form does not work in C#?

  - by Mike Rosenblum

  My question involves this simple walkthrough shown in the article Preserve Size and Location of Windows Forms – Part I by Dennis Wallentin. This approach works 100% fine when using VB.NET. When using the same steps in C#, however, the settings within the Settings tab of the application's properties looks correct, and the app.config file looks right, but the values are not saved when you run it. The app.config file winds up looking like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="WindowsAppCs.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> </sectionGroup> </configSections> <userSettings> <WindowsAppCs.Properties.Settings> <setting name="Location" serializeAs="String"> <value>0, 0</value> </setting> <setting name="Size" serializeAs="String"> <value>284, 262</value> </setting> </WindowsAppCs.Properties.Settings> </userSettings> </configuration> It looks right to me, but the values do not update when running hosted within Visual Studio or when running the compiled EXE. I am sure that something very simple needs to be added or done, but I don't know what. Does anyone have any ideas here? Much thanks in advance...

• DotNetNuke and Subversion guidelines

  - by David Stratton

  I've Googled, Binged, and here at StackOverflow, looked through the related questions and searched, but I'm not finding what I'm looking for. I've also searched documentation on DNN. What I'm looking for is any guidance (tutorials, blogs, step-by-step instructions for setting up a repository) etc from people who are experienced in using DotNetNuke with SVN. We use SVN for all our source control, and have no problem with standard applications, because we pretty much built the repository and directory structure to work with our processes. This means when we do web sites, in Visual Studio, we do file based web sites, rather than setting them up in the local IIS. It just makes things easier for us. However, with DNN, it appears that even if you get the source code, it is expecting to be set up in the local IIS, which means additional headaches for us. For example, we are moving all of our source code off our local C drives, and onto a shared drive on a server. This is to enable backups in addition to our normal source control. (This was a management decision). So that means that we need to change the virtual web app when we make the move. Has anyone come up with a good way to work around this? Can DNN be set up so that the developer web server in Visual Studio can be used, so that we can treat it just like any normal web app? Am I missing something obvious? Edit - added I'm willing to accept answers like "We tried it and never got it to work", and "It can't be done" as answers. I'm always open to hearing "It can't be done the way you want. You need to change your procedures to match how it works" if necessary. I guess if you've got experience trying this and just couldn't get it to work, I can learn from your experience that way as well, but some detail would be good.

• how to make war file take up less memory

  - by Myy

  I need help on how to decrease the memory usage of my web app. so I can fit more into my webserver. so I'm building a java web app with JSF 2.0 developing in eclipse helios and running on an Apache tomcat Server. And I have a dedicated virtual server with a tomcat aswell where I deploy these war files. the webApp is about 35MB in size ( it has a lot of jars and such) but when I deploy it to my tomcat webserver, I can see it takes about 300MB of RAM, is this normal? my dedicated server only has 2GB of ram from which normally have 1 to use. so I as soon as I deploy 3 apps I get an OOM error, I've gotten permgen OOM and a out of swamp Memory error; to fix this I upped my MaxPermGen to about a gig and resytarted the server to get back some swamp space. so I tried deploying smaller older apps ( about 15MB) and they take up waay less memory. If I have 1 GB of ram I want to be able to fit more apps into my webserver without getting any OOM Errors. now I found this stack overflow Question, Can that be applied to my case? and if so, which are the common folders in the tomcat server? anyone done this before or have a different more effective, not so complicated approach? Any ideas, and or commets are more than appreciated. Thanks! Myy

• JTA or LOCAL transactions in JPA2+Hibernate 3.6.0?

  - by Pangea

  We are in the process of re-thinking our tech stack and below are our choices (We can't live without Spring and Hibernate due to the complexity etc of the app). We are also moving from J2EE 1.4 to JEE 5. Tech stack JEE 5 JPA 2.0 (I know JEE 5 only supports JPA 1.0 but we want to use Hibernate as the JPA provider) Hibernate 3.6.0 (We already have lots of hbm files with custom types etc. so we doesn't want to migrate them at this time to JPA. This means we want both jpa/hbm mappings work together and hence the Hibernate as the JPA provider instead of using the default that comes with App Server) Now the problems is that I want to stick with local transactions but other team members want to use JTA. I have been working with J2EE for last 9 years and I've heard time and again people suggesting to stick with local transactions if I doesn't need two phase commits. This is not only for performance reasons but debugging/troubleshooting a local transaction is lot easier than a distributed transaction. My suggestion is to use spring declarative transaction management + local transactions (HibernateTransactionManager) I want to make sure if I am being paranoid or I have a valid point. I'd like to hear what the rest of the JEE world thinks. Thank you.
