  • How to solve lazy initialization exception using JPA and Hibernate as provider

    - by rupertin
    I am working on a project for a customer who wants to use lazy initialization. They always get "lazy initialization exception" when mapping classes with the default lazy loading mode. @JoinTable(name = "join_profilo_funzionalita", joinColumns = {@JoinColumn(name = "profilo_id", referencedColumnName = "profilo_id")}, inverseJoinColumns = {@JoinColumn(name = "funzionalita_id", referencedColumnName = "funzionalita_id")}) //@ManyToMany(fetch=FetchType.EAGER) - no exceptions if uncommented @ManyToMany private Collection<Funzionalita> funzionalitaIdCollection; Is there a standard pattern using JPA classes to avoid this error? Snippets are welcome, thanks a lot for your time.

  • Dynamically building and updating Histograms with JFreeChart

    - by job
    I've got a stream of incoming data that I would like to plot using a simple histogram. I don't know the range of values, or the proper resolution or bin width to use for the histogram. SimpleHistogramDataset provides some of this functionality, but I don't want to have to deal with catching exceptions in order to add new bins if the new value isn't covered. In addition, it doesn't easily allow me to rebuild the histogram using a different bin width (perhaps an integer multiples of some initial set width). Is there an easy way to accomplish this with JFreeChart or some alternate charting library, or am I going to have to write my own class here?

  • WMIprvse process leaks memory on 2008 server R2

    - by Dani Fischer
    I have a Windows 2008 R2 server running on a VM machine. My .NET service is running on this server periodically querying WMI, for example: SELECT ProcessId FROM Win32_Service WHERE ... After a day or two WMIprvse takes up to 500M memory and WMI queries start getting out of memory exceptions. This article seems to be talking about this issue: "http://support.microsoft.com/kb/958124" I've seen other articles saying that Microsoft is aware of the problem and not going to issue a fix until the next major release. http://social.msdn.microsoft.com/Forums/en/netfxbcl/thread/256eb40c-d050-4278-a3d8-863e30db02a0 I'd appreciate any suggestions and insights on this.

  • ExceptionPolicy.HandleException does not install Event Source for Logging in Registry if XBAP run ou

    - by Neo
    I am using the Logging Application Block (of Microsoft Enterprise Library) to log exceptions in the Event Viewer that occur in my WPF XBAP application. If I run the XBAP in the debugger from Visual Studio, an Event Source entry for my application is automatically created in the Registry at: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MyApp This occurs at the point ExceptionPolicy.HandleException() is called. However, if I run the XBAP outside of the IDE directly from the file system or from its published location, the Registry entry isn't added. Therefore, no logging takes place. I can only assume this is a security issue with running XBAP applications and they do not have access to write to the Registry. Is this a setting within my project? Any idea on why this might be happening? Any help much appreciated.

  • What can't I build in Silverlight?

    - by Refracted Paladin
    First, I know that Silverlight needs to be embedded in a website, usually an asp page. I understand I need a delivery boy. My question is this; What types of apps/projects are so filled with technological hurdles as to make them ridiculous to do in Silverlight versus ASP.net? I know that with perseverance and flexibility I can probably make EVERY app in Silverlight, in some version or another, but which ones would be blatantly simple in, say ASP.net(or even WPF) but quite complicated in Silverlight? Basically what I am asking is if there is any reason I shouldn't consider Silverlight my first stop for every problem, obvious exceptions not with standing(a service or console). For me specifically, at this point, I am only building in house apps.

  • Python-MySQLdb problem: wrong ELF class: ELFCLASS32

    - by jsalonen
    As part of trying out django CMS (http://www.django-cms.org/), I'm struggling with getting Python-MySQLdb to work (http://pypi.python.org/pypi/MySQL-python/). I have installed Django CMS and all of its dependencies (Python 2.5, Django, django-south, MySQL server) I'm trying out the example code within Django CMS code with MySQL as chosen database type When I execute python manage.py syncdb, the following error occurs: django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: /root/.python-eggs/MySQL_python-1.2.3c1-py2.5-linux-i686.egg-tmp/_mysql.so: wrong ELF class: ELFCLASS32 I have been able to trace the problem specifically to python-mySQLdb (as also visible in the stack trace). Other than that, I am completely puzzled. I don't have a clue what ELFCLASS32 means, or what ELF class is anyway. I suspect that this error could have something to do with the fact that I am running 64-bit version of Debian 5 (on a VPS). Any good ideas how to troubleshoot?

  • Java Web Service - Faulty Services - ClassNotFound Exception

    - by Epitaph
    My Project has 2 java files (A.java and B.java in same package). A.java uses methods in B.java. And, an external jar has been added in the project build path. In order to create a web service (bottom up) from the class, I created a new Dynamic Web Project in Eclipse with axis2 as the runtime platform, and imported A.java and B.java source files. Next, since all my methods that need to be exposed are contained in A.java, I right click on it and created web service using the standard settings. When I deploy the web service on my apache, I get "Fault Service" and a few ClassNotFound Exceptions for some of the classes in my external jar file (I have already imported it as an external jar). Does the external jar needs to be imported in another way?

  • Very simple Error handling with NServiceBus

    - by andy
    hey guys, here's a simple scenario NServiceBus Client/Server setup. The "Message" is a custom Class I wrote. The Client sends a request message. The Server receives the message, and the server does this: Bus.Reply(new UserDataResponseMessage { ID = Guid.NewGuid(), Response = users }); Then nothing. The Client never receives a response. Exception: By trawling through the log4net NServiceBus logs I find an exception, and it turns out that my customs class "users" is not marked as Serializable. Ok, how does one got about "throwing" or "handling" that kind of error? NServiceBus seems to promote the idea of not handling errors, but in this scenario its obvious to see some kind of "throw" would have saved a lot of time. How do I handle such exceptions, where do they occur, where do they go?

  • NHibernate 2.1.2 in medium trust.

    - by John
    I'm trying to configure nhibernate 2.1.2 to run in medium trust, without any luck. I have tried follwing the suggestions to run in medium trust and pre-generating the proxies. I then tried to remove all references to lazy loading setting the default-lazy="false" on all classes and bags. However this threw an exception asking me to configure the proxyfactory.factory_class None of these methds worked as they kept throwing generic security exceptions or throwing easying that libraries do not allow AllowPartiallyTrustedCallers. Am I using the wrong version of NHibernate if I want to run in medium trust? Is there a specific set of binaries, or source, which I should be using.

  • Invalid UTF-8 for Postgres, Perl thinks they're ok

    - by gorilla
    I'm running perl 5.10.0 and Postgres 8.4.3, and strings into a database, which is behind a DBIx::Class. These strings should be in UTF-8, and therefore my database is running in UTF-8. Unfortunatly some of these strings are bad, containing malformed UTF-8, so when I run it I'm getting an exception DBI Exception: DBD::Pg::st execute failed: ERROR: invalid byte sequence for encoding "UTF8": 0xb5 I thought that I could simply ignore the invalid ones, and worry about the malformed UTF-8 later, so using this code, it should flag & ignore the bad titles. if(not utf8::valid($title)){ $title="Invalid UTF-8"; } $data->title($title); $data->update(); However perl seems to think that the strings are valid, but it still throws the exceptions. How can I get perl to detect the bad UTF-8?

  • JAutodoc for Eclipse

    - by bizso09
    Hi, I'm trying to generate javadoc with JAutodoc 1.7 for Eclipse 3.5. I've sucessfully created templates for files, classes, methods. However, on parameters and exceptions I get the default @param and @throws tags generated even if I change the template in preferences/JAutodoc/templates/parameters. This is incompatible with the coding standards they have given us. Any help? Btw, I tried to use the default eclipse comment template but I couldn't find any enclosing_method_arguments variable in my version. Any ideas why that might be?

  • Does the CLR store small values in 'natural' sized locations?

    - by izb
    In Java, a byte or short is stored in the JVM's 'natural' word length, i.e. for the most part, 32-bits. An exception would be an array of bytes, where each byte occupies a byte of memory. Does the CLR do the same thing? If it does do this, in what situations are there exceptions to this? E.g. How much memory does this occupy? struct MyStruct { short s1; short s2; }

  • Problem restoring a SQL Server backup

    - by Elmex
    I have a SQL Server 2008, which is part of a domain. Now I make a backup of a database of this server and restore it on a SQL Server, which is not part of a domain. I have an C# application, which uses this database. On the NON-Domain machine I get now exceptions like this: "Cannot execute as the database prinzipal because the principial "dbo" does not exist, this type of principal cannot be impersonatedm or you don not have the permission" I think, the problem is, that the database owner is a domain user and this user doesn't exist on the target machine (backup machine)!? How can I solve this ?

  • ASP.NET HTTPHandler

    - by josephj1989
    I have an HttpHandler class (implements IHttphandler) where the path defined for the handler in web.config is *.jpg. I am requesting a Jpg image in my page. Within the HTTP Handler I am writing to a file in the filesystem. By mistake I was trying to write to a non existant directory. This should have thrown an exception but the execution simply proceeds.Ofcourse no file is writte. But if I give a proper directory the file is written correctly.Is there anything special about HttpHandler Exceptions. See part of the code public void ProcessRequest(HttpContext context){ File.WriteAllLines(context.Request.ApplicationPath+@"\"+"resul.log",new string[]{"Entered JPG Handler"});

  • Having trouble with match wildcards in array

    - by Senthil
    I've a master text file and exceptions file and I want to match all the words in exception file with master file and increase counter, but the trick is with wildcards. I'm able to do without wildcards with this: words = %w(aaa aab acc ccc AAA) stop = %q(/aa./) words.each do |x| if x.match(/aa./) puts "yes for #{x}" else puts "no for #{x}" end end = yes for aaa yes for aab no for acc no for ccc yes for AAA Also which would be the best way to go about this, using arrays or some other way. Edit: Sorry for the confusion. Yes stop has multiple wildcards and I want to match all words based on those wildcards. words = %w(aaa aab acc ccc AAA) stop = %q(aa* ac* ab*) Thanks

  • What is the right tool to detect VMT or heap corruption in Delphi ?

    - by Roland Bengtsson
    I'm a member in a team that use Delphi 2007 for a larger application and we suspect heap corruption because sometimes there are strange bugs that have no other explanation. I believe that the Rangechecking option for the compiler is only for arrays. I want a tool that give an exception or log when there is a write on a memory address that is not allocated by the application. Regards EDIT: The error is of type: Error: Access violation at address 00404E78 in module 'BoatLogisticsAMCAttracsServer.exe'. Read of address FFFFFFDD EDIT2: Thanks for all suggestions. Unfortunately I think that the solution is deeper than that. We use a patched version of Bold for Delphi as we own the source. Probably there are some errors introduced in the Bold framwork. Yes we have a log with callstacks that are handled by JCL and also trace messages. So a callstack with the exception can lock like this: 20091210 16:02:29 (2356) [EXCEPTION] Raised EBold: Failed to derive ServerSession.mayDropSession: Boolean OCL expression: not active and not idle and timeout and (ApplicationKernel.allinstances->first.CurrentSession <> self) Error: Access violation at address 00404E78 in module 'BoatLogisticsAMCAttracsServer.exe'.

EDIT3: The theory right now is that the Virtual Memory Table (VMT) is somehow broken. When this happen there is no indication of it. Only when a method is called an exception is raised (ALWAYS on address FFFFFFDD, -35 decimal) but then it is too late. You don't know the real cause for the error. Any hint of how to catch a bug like this is really appreciated!!! We have tried with SafeMM, but the problem is that the memory consumption is too high even when the 3 GB flag is used. So now I try to give a bounty to the SO community :) EDIT4: One hint is that according the log there is often (or even always) another exception before this. It can be for example optimistic locking in the database. We have tried to raise exceptions by force but in test environment it just works fine. EDIT5: Story continues... I did a search on the logs for the last 30 days now. The result: "Read of address FFFFFFDB" 0 "Read of address FFFFFFDC" 24 "Read of address FFFFFFDD" 270 "Read of address FFFFFFDE" 22 "Read of address FFFFFFDF" 7 "Read of address FFFFFFE0" 20 "Read of address FFFFFFE1" 0 So the current theory is that an enum (there is a lots in Bold) overwrite a pointer. I got 5 hits with different address above. It could mean that the enum holds 5 values where the second one is most used. If there is an exception a rollback should occur for the database and Boldobjects should be destroyed. Maybe there is a chance that not everything is destroyed and a enum still can write to an address location. If this is true maybe it is possible to search the code by a regexpr for an enum with 5 values ? EDIT6: To summarize, no there is no solution to the problem yet. I realize that I may mislead you a bit with the callstack. Yes there are a timer in that but there are other callstacks without a timer. Sorry for that. But there are 2 common factors. An exception with Read of address FFFFFFxx. Top of callstack is System.TObject.InheritsFrom (sys\system.pas:9237) This convince me that VilleK best describe the problem. I'm also convinced that the problem is somewhere in the Bold framework. But the BIG question is, how can problems like this be solved ? It is not enough to have an Assert like VilleK suggest as the damage has already happened and the callstack is gone at that moment. So to describe my view of what may cause the error: Somewhere a pointer is assigned a bad value 1, but it can be also 0, 2, 3 etc. An object is assigned to that pointer. There is method call in the objects baseclass. This cause method TObject.InheritsForm to be called and an exception appear on address FFFFFFDD. Those 3 events can be together in the code but they may also be used much later. I think this is true for the last method call. EDIT7: We work closely with the the author of Bold Jan Norden and he recently found a bug in the OCL-evaluator in Bold framework. When this was fixed these kinds of exceptions decreased a lot but they still occasionally come. But it is a big relief that this is almost solved.

  • How do I dinamically load raw assemblies that contains unmanaged code?(bypassing 'Unverifiable code

    I'm going to give an example of using System.Data.SQLite.DLL which is a mixed assembly with unmanaged code: If I execute this : var assembly= Assembly.LoadFrom("System.Data.SQLite.DLL") No exceptions are thrown, but if I do this : var rawAssembly = File.ReadAllBytes("System.Data.SQLite.DLL"); var assembly = Assembly.Load(rawAssembly); The CLR throws a FileLoadException with "Unverifiable code failed policy check. (Exception from HRESULT: 0x80131402)". Let's say I'm trying to load this assembly on a child AppDomain, how can I customize the AppDomain's security to allow me pass the policy check?

  • How to dispose NHibernate ISession in an ASP.NET MVC App

    - by Joe Young
    I have NHibernate hooked up in my asp.net mvc app. Everything works fine, if I DON'T dispose the ISession. I have read however that you should dispose, but when I do, I get random "Session is closed" exceptions. I am injecting the ISession into my other objects with Windsor. Here is my current NHModule: public class NHibernateHttpModule : IHttpModule { public void Init(HttpApplication context) { context.BeginRequest += context_BeginRequest; context.EndRequest += context_EndRequest; } static void context_EndRequest(object sender, EventArgs e) { CurrentSessionContext.Unbind(MvcApplication.SessionFactory); } static void context_BeginRequest(object sender, EventArgs e) { CurrentSessionContext.Bind(MvcApplication.SessionFactory.OpenSession()); } public void Dispose() { // do nothing } } Registering the ISession: container .Register(Component.For<ISession>() .UsingFactoryMethod(() => MvcApplication.SessionFactory.GetCurrentSession()).LifeStyle.Transient); The error happens when I tack the Dispose on the unbind in the module. Since I keep getting the session is closed error I assume this is not the correct way to do this, so what is the correct way? Thanks, Joe

  • Parsing C#, finding methods and putting try/catch to all methods

    - by erdogany
    I know it sounds weird but I am required to put a wrapping try catch block to every method to catch all exceptions. We have thousands of methods and I need to do it in an automated way. What do you suggest? I am planning to parse all cs files and detect methods and insert a try catch block with an application. Can you suggest me any parser that I can easily use? or anything that will help me... every method has its unique number like 5006 public static LogEntry Authenticate(....) { LogEntry logEntry = null; try { .... return logEntry; } catch (CompanyException) { throw; } catch (Exception ex) { logEntry = new LogEntry( "5006", RC.GetString("5006"), EventLogEntryType.Error, LogEntryCategory.Foo); throw new CompanyException(logEntry, ex); } } I created this for this; http://thinkoutofthenet.com/index.php/2009/01/12/batch-code-method-manipulation/

    Hi, the below code was working till few days back, but all of the sudden it started giving exception <cfpop action="getall" name="qMessage" server="mail.forestweb.com" port="995" username="email***@industryintel.com" password="******" timeout="30" /> I am running this code every 10 minutes to fetch the emails. And getting following exceptions: Message: An exception occurred when setting up mail server parameters. Detail : This exception was caused by: javax.mail.MessagingException: Connect failed; nested exception is: java.net.SocketTimeoutException: Read timed out. Can anyone please tell me why this is happening and if it has any solutions. Thanks in advance!!

  • NLog not logging messages on XP SP3 with .NET 3.5 Client Profile

    - by oltman
    I'm writing a program that is targeting the .NET 3.5 Client Profile and using NLog. I configure my logger programmatically on start up (no config file.) It works perfectly on Vista and Windows 7, but when running on a fresh install of XP SP3 with the .NET Client Profile installed, it will not log any of the variables in the layout string. For example, with the layout string set to: target.Layout = "MESSAGE: ${longdate}|${level}|${message}"; It will log "MESSAGE: | | |" Again, this only happens on XP SP3, and the logger is set to throw exceptions. Any ideas what may be causing this?

  • ctypes and PySide

    - by Timothy Baldridge
    I'm building an app with PySide, there's some image manipulation that needs to be done and using Python code for this is way too slow. Therefore I hacked out a .dll file that will do it for me. The function definition is as follows: extern "C" { QRectF get_image_slant(QImage *img, float slantangle, float offset) { Now I can load this function in via ctypes. But I can't seem to get ctypes to accept a QImage. I tried calling it like this: ext.get_image_slant(QImage(), 0, 0) And the reply I get is: File "<stdin>", line 1, in <module> ctypes.ArgumentError: argument 1: <type 'exceptions.TypeError'>: Don't know how to convert parameter 1 I tired casting the QImage to a c_void_p and it doesn't like that either. From what I can tell QImage() in python should map exactly to a QImage * in C, but Python doesn't seem to understand that.. Is there any way to force the casting?
