  • Spring transaction management breaks hibernate cascade

    - by TimmyJ
    I'm having a problem where the addition of spring's transaction management to an application causes Hibernate to throw the following error: org.hibernate.HibernateException: A collection with cascade="all-delete-orphan" was no longer referenced by the owning entity instance: org.fstrf.masterpk.domain.ReportCriteriaBean.treatmentArms org.hibernate.engine.Collections.processDereferencedCollection(Collections.java:96) org.hibernate.engine.Collections.processUnreachableCollection(Collections.java:39) org.hibernate.event.def.AbstractFlushingEventListener.flushCollections(AbstractFlushingEventListener.java:218) org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:77) org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26) org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) org.springframework.orm.hibernate3.SpringSessionSynchronization.beforeCommit(SpringSessionSynchronization.java:135) org.springframework.transaction.support.TransactionSynchronizationUtils.triggerBeforeCommit(TransactionSynchronizationUtils.java:72) org.springframework.transaction.support.AbstractPlatformTransactionManager.triggerBeforeCommit(AbstractPlatformTransactionManager.java:905) org.springframework.transaction.support.AbstractPlatformTransactionManager.processCommit(AbstractPlatformTransactionManager.java:715) org.springframework.transaction.support.AbstractPlatformTransactionManager.commit(AbstractPlatformTransactionManager.java:701) org.springframework.transaction.interceptor.TransactionAspectSupport.commitTransactionAfterReturning(TransactionAspectSupport.java:321) org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:116) org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) $Proxy92.saveNewReportCriteria(Unknown Source) org.fstrf.masterpk.domain.logic.MasterPkFacade.saveNewReportCriteria(MasterPkFacade.java:134) org.fstrf.masterpk.controllers.ReportCriteriaController.setupReportType(ReportCriteriaController.java:302) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) java.lang.reflect.Method.invoke(Method.java:585) org.springframework.web.bind.annotation.support.HandlerMethodInvoker.doInvokeMethod(HandlerMethodInvoker.java:413) org.springframework.web.bind.annotation.support.HandlerMethodInvoker.invokeHandlerMethod(HandlerMethodInvoker.java:134) org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter.invokeHandlerMethod(AnnotationMethodHandlerAdapter.java:310) org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter.handle(AnnotationMethodHandlerAdapter.java:297) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:875) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:809) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:571) org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:511) javax.servlet.http.HttpServlet.service(HttpServlet.java:710) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) I'm using Spring 2.5 and annotations to implement this management.

  • .NET read binary contents of .lnk file

    - by Flores
    I want to read the binary contents of a .lnk file. As long as the target of the shortcut (lnk file) exists this works fine with IO.File.ReadAllBytes(string file). BUT If the target of the shortcut does not exist (believe me I want this) the method only returns zero's. I guess this is because the OS follows the link and if it does not exist it returns zero's Is there some way to bypass the fact that the framework follows the target of the .lnk before displaying the contents of the .lnk file?

  • md5sum of large files gives different results sometimes

    - by Emanuele
    I have an AMD quad core, 8 gb RAM, 1 SSD EXT2 (2 months old), 2 HDD EXT4, approximately 1 year old. I'm using Ubuntu 10.04 x86-64 and when I compute the md5sum of large files (9 GB) sometimes I get different values than the one stored on a reference file. Upon restarting and switching off the PC then I get the expected results no matter how many times I repeat it. But this is random. I've turn on ECC (the fastest possible settings) and the issue seems to be rarer, but I've run memtest86+ for 6+ hours without a glitch (and with ECC off!). Any idea? Should I update the BIOS of my motherboard (Asus EVO-something...don't remember it now)? I've tried all the rest apart this, but genuinely don't know what to do anymore... Any suggestion is appreciated!

  • Is there a software that can remap the keys for a speficic keyboard?

    - by Vilx-
    There are several keyboards attached to my computer. I'd like to remap the keys on ONE of them, but keep the rest as they were. Is there a software that does this? As for the "why" - I have this idea that I'd like to have a "multimedia keypad" which is separate from my main keyboard, but I could not find any online. So I think that I could take a typical USB numpad (they cost like 5$), and remap the keys on one of them. Add appropriate stickers, and I'm all seat, cheaply. I know that it's theoretically possible, but before I get my hands dirty and write my own software, I'd like to see if there's maybe an existing one out there. Oh, yes, I'm running Windows 7.

  • Unit testing MVC.net Redirection

    - by Dan
    How do I Unit Test a MVC redirection? public ActionResult Create(Product product) { _productTask.Save(product); return RedirectToAction("Success"); } public ActionResult Success() { return View(); } Is Ayende's approach still the best way to go, with preview 5: public static void RenderView(this Controller self, string action) { typeof(Controller).GetMethod("RenderView").Invoke(self,new object[] { action} ); } Seems odd to have to do this, especially as the MVC team have said they are writing the framework to be testable.

  • class vs structure c#

    - by Enriquev
    I'm doing course 3354 (Implementing System Types and Interfaces in the .NET Framework 2.0) and it is said that for simple classes, with members variables and functions, it is better to use a struct than a class because of overhead. I have never heard of such a thing, what is the validity of this claim?

  • What exactly can concrete domains be used to describe?

    - by Exander
    I have read the formal definition of a "concrete domain", but I still don't quite get it. Could someone explain it to me in simpler terms, preferably with some examples? The definition is available in Reasoning in Description Logics with a Concrete Domain in the Framework of Resolution by Ullrich Hustadt, Boris Motik, Ulrike Sattler. Page 1, Definition 1.

  • What is the right way to use Internet Sharing in OS X?

    - by Bob King
    For a while now I've been using the Wireless in my Mac Mini as a seperate WiFi access point because my main router doesn't quite cover my whole house. There is a dedicated CAT 5E line down to the Mini, which has a static IP address. I've turned Internet Sharing on, using Airport/WiFi but it seems my options for security are limited. Can I do WPA2? Also, it seems like my iPhone only connects 25% of the time, and the rest of the time it claims I've given a bad password. I've tried "Forget this network" repeatedly.

  • Virtual Box - not filling entire screen

    - by jdavis
    I am new to VirtualBox and am trying to set up an instance of Windows 7 64. I have the virtual machine instance running with Windows 7 now installed, but it only fills up a small portion of my screen. Even when I go full screen, the window stays the same size and the rest of the screen is filled with gray space. I have installed VirtualBox Guest Additions, which allowed me to go from a resolution of 800x600 to 1024x768, but this still isn't satisfactory as my laptop display is 1600x900. Any help on this would be most appreciated. Thanks.

  • Efficient storage/retrieval method for replayable comet style applications (Google Wave, Etherpad)

    - by Gareth Simpson
    I am considering a web application that would have the same kind of multi user, automatic saving, infinite undo / replay capabilities that you see in Google Wave and Etherpad (albeit on a drastically smaller scale and userbase). Before I go away and reinvent the wheel, is this something that has already been addressed as either a piece of technology or library, or even just a design pattern. I know this isn't necessarily the best Stack Overflow question as there is probably not a "right" answer, but my Google-fu has failed me and I'd just like a reading list! Ordinarily I would be developing under python/django but this is not a firm requirement just a preference :)

  • What Web design tool would make a good CityDesk replacement?

    - by Joshua Fox
    I am looking for a tool for building static template-based web sites, your typical brochure-ware for a non-profit or a personal site. I have used CityDesk, but that is out-of-date, unsupported, and has certain problems. Of course there are lots of tools out there, but I cannot find anything similar to CityDesk: WYSIWYG as well as HTML coding a templating system not overdesigned like, say, Dreamweaver built for developers who understand HTML/JS/CSS but easier to use than hand-coding of PHP, Ruby, or other templates in a text editor supporting the editing of pages by non-developers preferably free I'd also like it to be CSS-aware; and to have lots of free templates available. Or alternatively, static template-based sites are often developed nowadays on the Web using a CMS like Django; is that the way to go? Edit: Namo, DreamWeaver, NetObjects Fusion, Coffee Cup, Evrsoft First Page, and Microsoft Expression might be candidates. I'll appreciate comments on these based on the criteria above.

  • Suggestions for open source testing tool for cloud computing

    - by vikraman
    Hi, I want to know if there is any open source testing tool for cloud computing. We have built a cloud framework with Xen, Eucalyptus, Hadoop, HBase as different layers. I am not looking at testing each of these tools separately, but i want to test them from the perspective of fitting into a cloud environment (for example scalability of xen hypervisor to handle multiple VMs). Would be great if you can suggest me some tool (open source) for the above.

    I want to have a seperate project that runs my server communication code in a normal JVM for the purposes of integration testing. This code uses these libraries which are build into the Android Framework... http://developer.android.com/reference/org/apache/http/client/package-summary.html Does anybody know what version of Apache HTTP Client this is supposed to be? I want to run it without the Android tests which are painfully slow.

  • Stack recommendations for small/medium-sized web application in Python

    - by reto
    I'm looking for some recommendations for a python web application. We have some memory restrictions and we try to keep it small and lean. We thought about using WSGI (and a python webserver) and build the rest ourself. We already have a template engine we'd like to use, but we are open for some suggestions regarding the whole request handling (the controller). The application has to run in a single process and the requests have to be processed with multiple threads. We've looked at django, but we are a not sure if it fits into our memory budget. Your feedback is very welcome! Cheers, Reto

  • Same command on multiple servers

    - by w00t
    Hello everyone. I'm just wondering if there is any fellow sysadmin with the need to execute one command on multiple servers. If so, what technique are you using? I have grown tired to ssh-ing to 3-5 servers and executing the same thing over and over again, so I'm thinking to make my life easier. Also, I think I should create keys so I don't have to enter passwords anymore (though I'm using root). After 2 years of doing this, I kind of developed a laziness. I googled it up, I know about cssh, pssh, tentakel (this one seems cool), and the more pro-genre - Puppet (of which I just heard of, didn't invest the time to read the docs). BTW, I'm using XP+putty, so if there is any putty-cool-thingy available, that's welcome too. If not, I can always ssh to one server and from there start my rest-of-the-servers-conquest :) *evil* Hit me up. Thanks.

  • HTML Encoding with ASP.NET

    - by Corin
    I am currently html encoding all user entered text before inserting/updating a db table record. The problem is that on any subsequent updates, the previously encoded string is reencoded. This endless loop is starting to eat up alot of column space in my tables. I am using parameterized queries for all sql statements but am wondering would it be safe to just let the .NET Framework handle this part without the HTML Encoding?
