  • How to disable JSR-303 Hibernate Validation in Spring3

    - by Pinchy
    After putting hibernate-validator.jar and javax.validation-api.jar in my classpath the org.springframework.dao.DataIntegrityViolationException is replaced by org.hibernate.exception.ConstraintViolationException and this is causing a lot of issues. I have to put this two jars to be able to upgrade Jersey to 2.4, it has dependency on these two jars. Putting these properties into hibernate.properties file doesn't help, hibernate simply ignores them but it loads the properties on start-up loaded properties from resource hibernate.properties: {hibernate.validator.apply_to_ddl=false,hibernate.validator.autoregister_listeners=false etc} javax.persistence.validation.mode=none hibernate.validator.autoregister_listeners=false hibernate.validator.apply_to_ddl=false I am using Spring 3.2.4 with SessionFactory and mapping resources from hbm.xml files with constraints in it, hibernate 3.6.9.final, hibernate-validator 5.0.final, javax.validator-api 1.1.0.Final I just can't figure out how to disable hibernate validation, any help will be much appreciated.

  • What does Rails script/server -d do differently that would cause a cells template to not be found

    - by Brian Deterling
    I'm using cells. I used the generator to create a cell so the path to my template was automatically chosen to be app/cells/displayer/table.html.erb where displayer is the name of the cell and table is the name of the state. When I run script/server in the foreground, everything works perfectly. But when I run script/server -d, I get "Missing template displayer/table.erb in view path app/cells:app/cells/layouts". Even if I change table.html.erb to table.erb, I see the same message - the ActionView code is checking both but not finding either. Even if you're not familiar with cells, does anyone know what happens differently in daemon mode related to view paths? In this case, it appears that the plugin is not correctly registering the view path.

  • Are concurrency issues possible when using the WCF Service Behavoir attribute set to ConcurrencyMode

    - by Brandon Linton
    We have a WCF service that makes a good deal of transactional NHibernate calls. Occasionally we were seeing SQL timeouts, even though the calls were updating different rows and the tables were set to row level locking. After digging into the logs, it looks like different threads were entering the same point in the code (our transaction using block), and an update was hanging on commit. It didn't make sense, though, because we believed that the following service class attribute was forcing a unique execution thread per service call: [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerCall)] We recently changed the concurrency mode to ConcurrencyMode.Single and haven't yet run into any issues, but the bug was very difficult to reproduce (if anyone has any thoughts on flushing a bug like that out, let me know!). Anyway, that all brings me to my question: shouldn't an InstanceContextMode of PerCall enforce thread-safety within the service, even if the ConcurrencyMode is set to multiple? How would it be possible for two calls to be serviced by the same service instance? Thanks!

  • Can a client determine whether the server has accept()'d a unix socket?

    - by Havoc P
    I'm dealing with a buggy server that will sometimes fail to accept() connections (but leaves its listening socket open). This is on Linux with unix domain sockets. Currently the only way to detect this is that after sending a bunch of data, the buffer fills up and blocks, and the server isn't sending any replies. This long-after-the-fact failure mode is hard to distinguish from other bugs - the server could be unresponsive for other reasons. Especially for unix domain sockets it seems the kernel should know whether accept() has occurred; is there any way to find this out? Can the client block until accept() happens somehow, or at least check whether it has? This is just for debugging purposes so it can be a little ugly.

  • Fast read of certain bytes of multiple files in C/C++

    - by Alejandro Cámara
    I've been searching in the web about this question and although there are many similar questions about read/write in C/C++, I haven't found about this specific task. I want to be able to read from multiple files (256x256 files) only sizeof(double) bytes located in a certain position of each file. Right now my solution is, for each file: Open the file (read, binary mode): fstream fTest("current_file", ios_base::out | ios_base::binary); Seek the position I want to read: fTest.seekg(position*sizeof(test_value), ios_base::beg); Read the bytes: fTest.read((char *) &(output[i][j]), sizeof(test_value)); And close the file: fTest.close(); This takes about 350 ms to run inside a for{ for {} } structure with 256x256 iterations (one for each file). Q: Do you think there is a better way to implement this operation? How would you do it?

  • Application lifecycle. How to run something only when application starts

    - by David
    I have a dialog popup to indicate how long I want an activity to run. Seems simple enough, but its difficult to determine when the activity is really starting. If the user opens the keyboard on a G1 and thereby goes into landscape, that reruns the activities onCreate method. I can't have a static for the class or even create an application class, because I can't determine when the 'application' goes away. Even after destroying the only activity, the application is apparently still alive. Is there a way to determine that onCreate has been called because of the keyboard being extended or landscape mode invoked? Thanks

  • IE6 image scaling with bicubic filter

    - by thehuby
    I have a project where I have to resize some images in the actual browser side. IE8, FF3 et al all apply a filter to smooth the resizing of the image, so in these browsers everything looks good. In IE7 I have applied the following fix which works great: -ms-interpolation-mode:bicubic; In IE6 however I can only find references to the AlphaImage Filter (the same one used to enable alpha transparency on PNG files). However I can't find an example of how to use it, nor have I been able to get it working myself. Can anyone provide me with an example? Preferably applied to actual img tags, though I could use background images if required. MSDN link (for what its worth): http://msdn.microsoft.com/en-us/library/ms532969%28VS.85%29.aspx The code I am using in my CSS is applied to the img, though I've tried applying it to the img container as well (with no effect): #provider-list li img { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src="/image.gif", sizingMethod="scale"); } A thousand thank you's in advance :) Rick

  • Removing WS_BORDER and WS_CAPTION from windows styles doesn't work

    - by lordfrikk
    Hello, I created a small app in C# that removes border and caption from window, then it sets size to the user's resolution and centers it. It's a utility for me to use when I want to play games in windowed mode without being annoyed by the borders. Everything works fine with most games, but I tried to use it on a recently released game Alpha Protocol and it doesn't work. I could almost say that the game reverts my changes, but I'm not sure how to tell if that's true or not. I'm using imported API functions MoveWindow, SetWindowLong and SetWindowPos. Snippet: Win32.MoveWindow(hWnd, 0, 0, Convert.ToInt32(sizeXText.Text), Convert.ToInt32(sizeYText.Text), true); Win32.SetWindowLong(hWnd, GWL_STYLE, Win32.GetWindowLong(hWnd, GWL_STYLE) & ~WS_CAPTION & ~WS_BORDER); Win32.SetWindowPos(hWnd, 0, 0, 0, 0, SWP_NOZORDER|SWP_NOMOVE|SWP_NOSIZE|SWP_NOACTIVATE|SWP_DRAWFRAME);

  • Get C# Templates For VS 2008 Shell

    - by Onorio Catenacci
    I've got VS 2008 Shell Integrated mode; I've got F# 2.0 on that installation. Till now this has worked fine for me because I've been hacking at F# code. Now though, I want to install Intellifactory's WebSharper. It looks like the Intellifactory templates assume that C# templates will be available because while it will create the F# portion of the solution it will not create the Web project in the solution with the complaint A problem was encountered creating the sub project 'Web Application'. The template specified cannot be found. Is there any place where I can get the C# stuff to add to this instance of VS 2008 Shell? Apologies in advance if this is a dup question but I've googled without much luck and I don't seem to find this here either. I've seen that about devenv /installvstemplates but that also fails with a message about needing to elevate privileges (which is odd since I try it under an admin user).

  • How to allow netNamedPipeBinding to work with requiring UAC?

    - by Rohit
    I have a service running under Local system account. I have an application that run in a non-UAC mode. Both interact with each other as both act as server and client. Application as client can communicate with Service. But Service as client cannot communicate with application. If I run with UAC the problem is solved. <customBinding> <binding name="net.pipe"> <namedPipeTransport /> </binding> </customBinding>

  • Qt for Symbian - Detecting touch/non-touch devices...

    - by Nikos
    I'm porting a game for Symbian which supports both a touch & non-touch UI. I need to be able to tell if the device has a touch screen on start-up so I can enable the appropriate mode. After googling for hours and going though the Qt Docs I found QSysInfo but this merely provides the version of the Symbian device. Is there a way to get the actual capabilities of the device? There must be a way to tell if the device has a touch screen...! I'm using the latest QtCreator with the NokiaSDK. Thank you in advance, Nikos.

  • CSS for mobile sometimes reverts back to original

    - by Jessie
    So most of the time my stylesheets appear properly. The standard/original one always works flawlessly, however it seems sometimes the mobile one is disregarded when looked at from a mobile device I have them designated as follows: <link runat="server" href="CustomStyleSheets/Menu.css" rel="stylesheet" type="text/css" /> <link href="CustomStyleSheets/mobile.css" rel="stylesheet" type="text/css" media="only screen and (max-device-width: 799px)" /> I'm using a Droid X to view the page, in portrait mode, so the device width shouldn't be exceeding the max-width specified above, but sometimes, randomly, it still reverts back to the original css page. Any way to keep it from doing so?

  • LINQ-to-XML to DataGridView: Cannot edit fields -- How to fix?

    - by Pretzel
    I am currently doing LINQ-to-XML and populating a DataGridView with my query just fine. The trouble I am running into is that once loaded into the DataGridView, the values appear to be Un-editable (ReadOnly). Here's my code: var barcodes = (from src in xmldoc.Descendants("Container") where src.Descendants().Count() > 0 select new { Id = (string)src.Element("Id"), Barcode = (string)src.Element("Barcode"), Quantity = float.Parse((string)src.Element("Quantity").Attribute("value")) }).Distinct(); dataGridView1.DataSource = barcodes.ToList(); I read somewhere that the "DataGridView will be in ReadOnly mode when you use Anonymous types." But I couldn't find an explanation why or exactly what to do about it. Any ideas?

  • sorting content of a text file in python

    - by rabidmachine9
    I have this small script that sorts the content of a text file # The built-in function `open` opens a file and returns a file object. # Read mode opens a file for reading only. try: f = open("tracks.txt", "r") try: # Read the entire contents of a file at once. # string = f.read() # OR read one line at a time. #line = f.readline() # OR read all the lines into a list. lines = f.readlines() lines.sort() f = open('tracks.txt', 'w') f.writelines(lines) # Write a sequence of strings to a file finally: f.close() except IOError: pass the only problem is that the text is displayed at the bottom of the text file everytime it's sortened... I assume it also sorts the blank lines...anybody knows why? thanks in advance

  • Is there a cleaner way to Bind property to owner's DataContext?

    - by Dan Bryant
    I have some code that looks like this: <Expander Header="{Binding SelectedSlot.Name}" Visibility="{Binding ShowGroupSlot, Converter={StaticResource BooleanToVisibility}}"> <Controls:GroupPrototypeSlotControl Slot="{Binding DataContext.SelectedSlot, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Expander}}}" /> </Expander> This works, but the ugliness of the Slot Binding bothers me. This is required because the GroupPrototypeSlotControl has a GroupPrototypeViewModel as its DataContext. If I simply use {Binding SelectedSlot}, it attempts to resolve it on the 'child' ViewModel, which fails. I get around this by explicitly looking at the DataContext of my parent control. Is there a cleaner way to do this type of binding?

  • textures and vertex arrays with OpenGL?

    - by user146780
    Basically what I'd like to do is make textured NGONS. I also want to use a tesselator (GLU) to make concave and multicontour objects. I was wondering how the texture comes into play though. I think that the tesselator will return verticies so I will add these to my array, that's fine. But my vertex array will contain more than one polygon object so then how can I tell it when to bind the texture like in immediate mode? Right now I feel stuck with one call to bind. How can this be done? Thanks

  • Getting Raw XML From SOAPMessage in Java

    - by Daniel Lew
    I've set up a SOAP WebServiceProvider in JAX-WS, but I'm having trouble figuring out how to get the raw XML from a SOAPMessage (or any Node) object. Here's a sample of the code I've got right now, and where I'm trying to grab the XML: @WebServiceProvider(wsdlLocation="SoapService.wsdl") @ServiceMode(value=Service.Mode.MESSAGE) public class SoapProvider implements Provider<SOAPMessage> { public SOAPMessage invoke(SOAPMessage msg) { // How do I get the raw XML here? } } Is there a simple way to get the XML of the original request? If there's a way to get the raw XML by setting up a different type of Provider (such as Source), I'd be willing to do that, too.

  • Praat scripting

    - by Binaryrespawn
    Hi all, I am trying to write a praat script to do preprocessing on hundreds of speach samples. I need to extract speech features from each sample and feed these as imputs into a feed-forward neural network. I have already constructed the network using math-lab. However, learing to script in praat is proving to be quite a challenge given my time constraints. Some of my samples are 0.01 to 0.03 seconds in length, I was looking at standardising the duration for all samples using Pitch Synchronous OverLap-Add(PSOLA). However this will be very tedious if I were to do this for every sample. Is there any script that can read in all of my files and perform the operations in a batch mode? Any guidance will be surelly appreaciated. Regards.

  • How to set timeout for exclusive lock in PostgreSQL

    - by Low Kian Seong
    I have an import script that was failing because of the 'Exclusive nowait' option I set my script. This caused the script to error out the first time it could not get the exclusive lock on the table. My script did it this way: "LOCK TABLE %s IN EXCLUSIVE MODE NOWAIT" Now my script works it's just that I want to be able to set the timeout for PostgreSQL instead of having it wait for the maximum time which is 15mins. I prefer to set it in posgresql.conf. Is there a way to do this?

  • iphone/ipad application - taking screen shot

    I successfully implemented an application that works on ipad as well as on iphone. In that I provided option to user to send the screen shot of the application as mail attachment. Even that is functioning well. But my code is taking screen shot irrespective of orientation. The image i'm getting is always in portrait mode. I want to take the screen shot depending on the orientation of ipad/iphone and send the image as attachment. I'm using following code to take the screen shot. UIGraphicsBeginImageContext(screenWindow.frame.size); [screenWindow.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *screenshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext();

  • ASP.Net: Finding the cause of OutOfMemoryExpcetions

    - by Keith Bloom
    I trying to track down the cause of an OutOfMemory for a website. This site has ~12,000 .aspx pages and the last time it crashed I captured a memory dump using adplus. After some investigation I found a lot of heap fragmentation, there are around 100MB of Free blocks which can't be assigned. Digging deeper one of the Large Object Heaps is fragmented and the causes seems to be String interning as described [here][1] Could this be caused by the number of pages in the site? As they are all compiled they sit in memory and by looking at the dump they are interned and PINNED which I think means they stick around for a while. I would find this odd as there are many sites with more pages, but dynamic compilation could account for the growth in memory. What other methods are there for finding the cause of the memory leak? I have tried to capture a dump using adplus in hang mode but this fails and the IIS worker process get recycled. [1]: • http://stackoverflow.com/questions/686950/large-object-heap-fragmentation
