  • Hibernate schema parameter doesn't work in @SequenceGenerator annotation

    - by tabdulin
    I hav the following code: @Entity @Table(name = "my_table", schema = "my_schema") @SequenceGenerator(name = "my_table_id_seq", sequenceName = "my_table_id_seq", schema = "my_schema") public class MyClass { @Id @GeneratedValue(generator = "my_table_id_seq", strategy = GenerationType.SEQUENCE) private int id; } Database: Postgresql 8.4, Hibernate annotations 3.5.0-Final. When saving the object of MyClass it generates the following SQL query: select nextval('my_table_id_seq') So there is no schema prefix and therefore the sequence cannot be found. When I write the sequenceName like sequenceName = "my_schema.my_table_id_seq" everything works. Do I have misunderstandings for meaning of schema parameter or is it a bug? Any ideas how to make schema parameter working?

  • UdpClient receiving and sending at the same time

    - by SoMoS
    Hello, I am maintaining other's code and its using the class UdpClient. The code declares one instance of UdpClient and receives data continuosly using the UdpClient.Receive(). When data is received it is processed in another thread and the UdpClient calls Receive() again. At the same time when the data is processed the same client is sending a response back. Question: Is this a bug? I think so because UdpClient is not thread safe so you can not call two methods at the same time. Anyways code is working fine but ...

  • Flowplayer: Clicking on the player forces is to reload.

    - by PaulDavis
    Hey everyone, I've got this damn annoying bug (or wrong setting) that makes the player reload whenever it's clicked. It's set to play when you click, so when you click it, it reloads. The circle begins.... The reloading only happens in Firefox. In Safari (and I assume Chrome), the video opens in its own window. Not ideal, but it still plays. Here's the code for the player: (I can't share the link unfortunately, NDAs etc etc.) flashembed("player", "/flowplayer.commercial-3.0.7.swf", { config: { key: '#@xxxxxx', clip: { autoPlay: false, autoBuffering: true, url: "http://myvid.com/url.mp4", wmode: 'opaque' } } }); This site is full of complete geniuses, I hope one of you can help me out!

  • recv returns old data

    - by anon
    This loop is supposed to take data from a socket line by line and put it in a buffer. For some reason, when there is no new data to return, recv returns the last couple lines it got. I was able to stop the bug by commenting out the first recv, but then I cant tell how long the next line will be. I know it's not a while(this->connected){ memset(buf, '\0', sizeof(buf)); recv(this->sock, buf, sizeof(buf), MSG_PEEK); //get length of next message ptr = strstr(buf, "\r\n"); if (ptr == NULL) continue; err = recv(this->sock, buf, (ptr-buf), NULL); //get next message printf("--%db\n%s\n", err, buf); tok[0] = strtok(buf, " "); for(i=1;tok[i-1]!=NULL;i++) tok[i] = strtok(NULL, " "); //do more stuff }

  • Exception thrown while working with JTabbedPane

    - by Halo
    I'm using a JTabbedPane in my application and I listen to its changes with ChangeListener so that I can know which tab is currently selected. So my stateChanged method is; public void stateChanged(ChangeEvent e) { currentPageIndex = jTabbedPane.getSelectedIndex(); } But while I'm adding new tabs to the JTabbedPane it throws an ArrayIndexOutOfBoundsException in the method above, I don't know why. Some suggested for a similar case that this is a bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4873983, but as you'll see some says the solution is to work with Swing from EventDispatchThread. What does it mean, do they mean the SwingUtilities.invokeLater thing? Can someone show me how I can modify my stateChanged method accordingly to avoid the exception?

  • How convince other developers not to ignore Exceptions?

    - by Mnementh
    Recently I encountered a bug in an application I took over from another developer. I debugged for the reason and over an hour later I realized, that the problem wasn't the code producing the exception, but some code executed before this returning wrong data. If I dived into this, I encountered the following: try { ... } catch (XYException e){} If the Exception would have been propagated (a change I did), I would have found the reason for the bugs in a few minutes, as the stacktrace had pointed me to the problem. So how can I convince other developers to never catch and ignore exceptions in this way?

  • Can I get the stack traces of all threads in my c# app?

    - by Drew Shafer
    I'm debugging an apparent concurrency issue in a largish app that I hack on at work. The bug in question only manifests on certain lower-performance machines after running for many (12+) hours, and I have never reproduced it in the debugger. Because of this, my debugging tools are basically limited to analyzing log files. C# makes it easy to get the stack trace of the thread throwing the exception, but I'd like to additionally get the stack traces of every other thread currently executing in my AppDomain at the time the exception was thrown. Is this possible?

  • Occasional InterruptedException when quitting a Swing application

    - by Joonas Pulakka
    I recently updated my computer to a more powerful one, with a quad-core hyperthreading processor (i7), thus plenty of real concurrency available. Now I'm occasionally getting the following error when quitting (System.exit(0)) an application (with a Swing GUI) that I'm developing: Exception while removing reference: java.lang.InterruptedException java.lang.InterruptedException at java.lang.Object.wait(Native Method) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:118) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:134) at sun.java2d.Disposer.run(Disposer.java:125) at java.lang.Thread.run(Thread.java:619) Well, given that it started to happen with a more concurrency-capable hardware, and it has to do with threads, and it happens occasionally, it's obviously some kind of timing thing. But the problem is that the stack trace is so short. All I have is the listing above. It doesn't include my own code at all, so it's somewhat hard to guess where the bug is. Has anyone experienced something like this before? Any ideas how to start solving it?

  • (iPhone) Instruments can't "Attach to Process"

    - by AlexLive
    Actually, I'm using a second generation Ipod Touch. What I'm trying to do is to debug my app on XCode and look for any memory leaks on Instruments at the same time. Is it even possible? Because the "Attach to Process" submenu lists when my app is running (or debugging in this case) but all the items inside this menu are disabled. All I can do is start the app from Instruments but later I come across some bug and I want to see the variables and properties affected. I'm also new to Instruments. Please, could someone give me any advice? Help would be greatly appreciated!

  • C# Windows Forms Print Dialog box click OK twice to respond

    - by sbartlett007
    I'm using Visual Studio 2008, .net Framework 3.5 for a Windows forms client-server app that I'm working on. There is a weird bug when I run the program and try to print. The print dialog box opens, but I have to click the OK button twice for it to work. After the second click it works fine, no errors. When I put a breakpoint on: if (result == DialogResult.OK) , the breakpoint doesn't trigger until the second click. Here is the code: private void tbPrint_Click(object sender, EventArgs e) { try { printDialog1.Document = pDoc; DialogResult result = printDialog1.ShowDialog(); if (result == DialogResult.OK) { pDoc.PrinterSettings.PrinterName = printDialog1.PrinterSettings.PrinterName; pDoc.Print(); } ... This is driving me crazy, and I can't see anything else that would interfere with it.

  • Should I distinguish OpenIDs based on protocol prefix or not? http vs https

    - by Joannes Vermorel
    I have implemented a straightforward OpenID support for my ASP.NET app with DotNetOpenAuth. Yet I recently realized that the implementation was treating http://johndoe.example.com/ as a distinct user compared to https://johndoe.example.com. This lead to quite a few confused users. I am unsure what to do at this point. Is this a bug or a feature? Indeed, I can consider this behavior as a feature: if the user specifies the HTTPS, the user might not want the system to accept HTTP auth in the first place. On the other hand: if the user specifies HTTPS out of sheer cluelessness (the casual web visitor is clueless concerning the purpose of the "S" part), then rejecting it's authentication attempt is confusing. What is considered as the best practice?

  • Why don't web fonts in Firefox don't work on a different domain?

    - by mikez302
    I was experimenting with the fancy new OpenType font capability in Firefox 3.5 and I ran into a problem. I was trying to embed a font on a different domain than the page it would be used on, and it didn't work. I thought it may have been a bug, but from what I read on the MDC reference page, I noticed this note: In Gecko, web fonts are subject to the same domain restriction (font files must be on the same domain as the page using them), unless HTTP access controls are used to relax this restriction. It looks like they designed the browser that way on purpose. Out of curiosity, why would they do that? Is there any security risk with embedding a font? Or is it for legal trademark or copyright issues? Or something else?

  • How do I give MacPorts privileges?

    - by cojadate
    I tried to install PostgreSQL server development libraries using MacPorts and got the following: Warning: MacPorts running without privileges. You may be unable to complete certain actions (e.g. install). ---> Computing dependencies for postgresql-server-devel ---> Dependencies to be installed: postgresql-devel ---> Building postgresql-devel Error: Target org.macports.build returned: shell command failed Error: The following dependencies failed to build: postgresql-devel Error: Status 1 encountered during processing. To report a bug, see <http://guide.macports.org/#project.tickets> So I guess that means I need to running MacPorts with privileges and try again. Unfortunately I've no idea how to give MacPorts privileges. I'm running OS X 10.6.3

  • Perl "Day too big" - root cause

    - by azp74
    I have been helping someone debug some code where the error message was "Day too big". I know that this springs from localtime and the Y2038 bug (most google results appear to be people dealing with cookies expiring well into the future). We appear to have 'fixed' the problem by using time to get the current date. However, given that none of our original dates should have hit the 2038 issue I'm sceptical that we've actually fixed the problem ... Are there other instances that anyone knows of where one would hit "day too big"?

  • Base64 Android encode to PHP decode make error

    - by studio lambda
    I'm a french guy, so, I'm sorry for my english... I'm developing an Android App which communicate with a PHP REST service. So, when I try to encode an image file into Base64 like this : InputStream fileInputStream = context.getContentResolver().openInputStream(uri); BufferedInputStream in = new BufferedInputStream(fileInputStream); StringWriter out = new StringWriter(); int b; while ((b = in.read()) != -1) out.write(b); out.flush(); out.close(); in.close(); String encoded = new String(android.util.Base64.encode(out.toString() .getBytes(), android.util.Base64.DEFAULT)); On server side, I make : $data=base64_decode(chunk_split($base64BinaryData)); The result is that my image file is corrupted! INFO : the image is made by an Intent to android.provider.MediaStore.ACTION_IMAGE_CAPTURE Activity in Emulator mode (avd 5554) I've already read lots of discussions about similar problem but nothing fix my bug. thanks for help Regards,

  • Is Stopwatch really broken?

    - by Jakub Šturc
    At MSDN page for Stopwatch class I discovered link to interesting article which makes following statement about Stopwatch: However there are some serious issues: This can be unreliable on a PC with multiple processors. Due to a bug in the BIOS, Start() and Stop() must be executed on the same processor to get a correct result. This is unreliable on processors that do not have a constant clock speed (most processors can reduce the clock speed to conserve energy). This is explained in detail here. I am little confused. I've seen tons of examples of using Stopwatch and nobody mention this drawbacks. How serious is this? Should I avoid using Stopwatch?

  • Casting to generic type in Java doesn't raise ClassCastException?

    - by Kip
    I have come across a strange behavior of Java that seems like a bug. Is it? Casting an Object to a generic type (say, K) does not throw a ClassCastException even if the object is not an instance of K. Here is an example: import java.util.*; public final class Test { private static<K,V> void addToMap(Map<K,V> map, Object ... vals) { for(int i = 0; i < vals.length; i += 2) map.put((K)vals[i], (V)vals[i+1]); //Never throws ClassCastException! } public static void main(String[] args) { Map<String,Integer> m = new HashMap<String,Integer>(); addToMap(m, "hello", "world"); //No exception System.out.println(m.get("hello")); //Prints "world", which is NOT an Integer!! } }

  • Activate different Maven profiles depending on current module?

    - by Yaba
    We have a multi module build with modules using different technologies, like Java and Flex. Is it somehow possible to activate different profiles based on the module that is compiled currently? I tried it with an activation like <profile> <id>flex</id> <activation> <file> <exists>${basedir}/src/main/flex</exists> </file> </activation> ... </profile But it didn't work, although the use of ${basedir} is documented in the Maven documentation (this is a bug in Maven). Is there a different possibility to have different activations based on the current module? Or does Maven only allow to activate a profile for all modules or not at all?

  • multiline gtk.Label ignores xalign=0.5

    - by thomas
    A gtk.Label can't be aligned in center when line-wrap is turned on. Example code: import pygtk pygtk.require('2.0') import gtk class testwin(gtk.Window): def __init__(self): gtk.Window.__init__(self) width,height = 300,300 self.set_size_request(width,height) self.set_position(gtk.WIN_POS_CENTER) self.set_title("test window") label = gtk.Label("test text") label.set_line_wrap(True) label.set_justify(gtk.JUSTIFY_CENTER) label.set_alignment(0.5,0.5) label.connect("size-allocate",lambda l,s: l.set_size_request(s.width-1, -1)) self.add(label) self.connect("destroy", gtk.main_quit) self.show_all() testwin() gtk.main() It looks like this, that means, it's aligned left: http://m45.img-up.net/?up=pic122x97.png If you comment out line 14 (set_line_wrap) everything is perfectly fine: http://o54.img-up.net/?up=pic2y00p9.png Please note that yalign works fine. So it seems like the first argument in the gtk.Misc.set_alignment-function has no effect when line wrap is turned on. Using Fedora 16, 64bit, gtk 3.2.4, pygtk 2.24.0, python 2.7.2 Question: Is this intended or a bug? How is it supposed to be made or is a workaround available?

  • SML/NJ incomplete match

    - by dimvar
    I wonder how people handle nonexhaustive match warnings in the SML/NJ compiler. For example, I may define a datatype datatype DT = FOO of int | BAR of string and then have a function that I know only takes FOOs fun baz (FOO n) = n + 1 The compiler will give a warning stdIn:1.5-1.24 Warning: match nonexhaustive FOO n = ... val baz = fn : DT - int I don't wanna see warnings for incomplete matches I did on purpose, because then I have to scan through the output to find a warning that might actually be a bug. I can write the function like this fun baz (FOO n) = n + 1 | baz _ = raise Fail "baz" but this clutters the code. What do people usually do in this situation?

  • Howto troubleshoot vb6 dll 800a01ad error in c# application

    - by phq
    I have a dll that I created from a VB6 project that I am now using in a c# project. This has worked before but now when I try to return to the c# project to fix a bug, the program get a COMException stating roughly translated: Could not create an instance of COM-component with CLSID {085E3494-9F78-47D5-B0E6-FA460FD3CBED} from IClassFactory because of the following error: 800a01ad. So I try to create a new empty c# project with only one line in the main function: OurNamespace.OurClass foo = new OurNamespace.OurClass(); Which fails with the same error. I have registered the dll but that did not change the outcome of the problem. The problem only occurs on the machine I am currently at, still I'm interested to understand the problem so that I know how to fix it if it occurs on a customers computer.

  • Blackberry JDE generating bad .jad file (does not match compiled .cod file)

    - by matkas
    I Have a BB application that gets compiled into 3 siblings cod file. ( actualy one cod fil contaning 3 sub cod files). app.cod |--app.cod |--app-1.cod |--app-2.cod which is normal. the jad refers to those 3 inner .cod files. Now I have add some feature to my app, it is getting a little bit bigger. the jad now refers to 4 inner .cod files. but there is still 3 inside the app.cod that is generated. so I now still have app.cod |--app.cod |--app-1.cod |--app-2.cod but with the jad refering to app.cod app-1.cod app-2.cod AND app-3.cod. what is wrong the my compiled program? is it a bug from the JDE? I am using JDE 4.5.

  • Is Android AVD's firewall somehow more restricted to real Android firewall?

    - by hhh
    I have a TCP server running in AVD and a TCP client running in AVD. AVD client dies because the connection refused so we are doubting some restricted firewall settings. I turned off the firewall in my Debian -laptop with this here but it did not fix the problem so some issue with Android -emulator, intro here. How can I make a TCP connection from one AVD to another AVD in the same laptop in Android? Grap the code & Minimal Working Example: You can find the sources here: import to Eclipse, set up two pieces of 2.3.3 AVDs, set up Test-running-configurations for server and client. Then "Run as Configuration" and you should see this bug. I don't have a physical Android -phone to test the code so I cannot comment whether it works with real Androids.

  • Strategies for Error Handling in .NET Web Services

    - by Jarrod
    I have a fairly substantial library of web services built in .NET that I use as a data model for our company web sites. In most .NET applications I use the Global ASAX file for profiling, logging, and creating bug reports for all exceptions thrown by the application. Global ASAX isn't available for web services so I'm curious as to what other strategies people have come up with to work around this limitation. Currently I just do something along these lines: <WebMethod()> _ Public Function MyServiceMethod(ByVal code As Integer) As String Try Return processCode(code) Catch ex As Exception CustomExHandler(ex) 'call a custom function every time to log exceptions Return errorObject End Try End Function Anybody have a better way of doing things besides calling a function inside the Catch?
