  • Seam cache provider with ehcache null

    - by Cateno Viglio
    Hi every one, I'm trying to configure seam/ehcache following the tutorial from jboss page: http://docs.jboss.org/seam/2.1.2/reference/en-US/html/cache.html I put the ehcache.1.2.3.jar in project.ear/lib and injected CacheProvider as especified, but the CacheProvider always return null. The documentation doesn't show any aditional configuration for ehcache, just for jboss cache. I am probably doing something wrong, it's impossible be so easy :). besides put the jar in /lib, i created the following seam component to test: @Scope(ScopeType.SESSION) @Name("cacheBean") public class CacheSeamBean implements java.io.Serializable { @In(required=false, create=true) private EntityManager em; @Logger private Log log; @In private Events events; @In CacheProvider cacheProvider; Boolean blLoaded = Boolean.FALSE; @Create public void buscar() { if (!blLoaded){ List<Parametro> lstParametro = em.createQuery("select p from Parametro p").getResultList(); for (Parametro parametro : lstParametro){ cacheProvider.put(parametro.getCodigo(), parametro.getValor()); } blLoaded= Boolean.TRUE; } } } Thanks

  • Action Filter Dependency Injection in ASP.NET MVC 3 RC2 with StructureMap

    - by Ben
    Hi, I've been playing with the DI support in ASP.NET MVC RC2. I have implemented session per request for NHibernate and need to inject ISession into my "Unit of work" action filter. If I reference the StructureMap container directly (ObjectFactory.GetInstance) or use DependencyResolver to get my session instance, everything works fine: ISession Session { get { return DependencyResolver.Current.GetService<ISession>(); } } However if I attempt to use my StructureMap filter provider (inherits FilterAttributeFilterProvider) I have problems with committing the NHibernate transaction at the end of the request. It is as if ISession objects are being shared between requests. I am seeing this frequently as all my images are loaded via an MVC controller so I get 20 or so NHibernate sessions created on a normal page load. I added the following to my action filter: ISession Session { get { return DependencyResolver.Current.GetService<ISession>(); } } public ISession SessionTest { get; set; } public override void OnResultExecuted(System.Web.Mvc.ResultExecutedContext filterContext) { bool sessionsMatch = (this.Session == this.SessionTest); SessionTest is injected using the StructureMap Filter provider. I found that on a page with 20 images, "sessionsMatch" was false for 2-3 of the requests. My StructureMap configuration for session management is as follows: For<ISessionFactory>().Singleton().Use(new NHibernateSessionFactory().GetSessionFactory()); For<ISession>().HttpContextScoped().Use(ctx => ctx.GetInstance<ISessionFactory>().OpenSession()); In global.asax I call the following at the end of each request: public Global() { EndRequest += (sender, e) => { ObjectFactory.ReleaseAndDisposeAllHttpScopedObjects(); }; } Is this configuration thread safe? Previously I was injecting dependencies into the same filter using a custom IActionInvoker. This worked fine until MVC 3 RC2 when I started experiencing the problem above, which is why I thought I would try using a filter provider instead. Any help would be appreciated Ben P.S. I'm using NHibernate 3 RC and the latest version of StructureMap

  • Setting spring bean property value using ref-bean

    - by Apache Fan
    Hi, I am trying to set a property value using spring. <bean id="velocityPropsBean" class="com.test.CustomProperties" abstract="false" singleton="true" lazy-init="false" autowire="default" dependency-check="default"> <property name="properties"> <props> <prop key="resource.loader">file</prop> <prop key="file.resource.loader.cache">true</prop> <prop key="file.resource.loader.class">org.apache.velocity.runtime.resource.loader.FileResourceLoader</prop> <prop key="file.resource.loader.path">NEED TO INSERT VALUE AT STARTUP</prop> </props> </property> </bean> <bean id="velocityResourcePath" class="java.lang.String" factory-bean="velocityHelper" factory-method="getLoaderPath"/> Now what i need to do is insert the result from getLoaderPath into file.resource.loader.path. The value of getLoaderPath changes so it has to be loaded at server startup. Any thoughts how i can inset the velocityResourcePath value to the property?

  • How to transfer url parameters to repoze custom predicate checkers

    - by user281521
    I would like to create a repoze custom predicate checker that is capable to access url parameters and validate something. But I would like to use allow_only to set this permission checker in all the controller's scope. Something like: class MyController(BaseController): allow_only = All(not_anonymous(msg=l_(u'You must be logged on')), my_custom_predicate(msg=l_(u'something wrong'))) def index(self, **kw): return dict() then, my_custom_predicate should check the url paramters for every request in every MyController method, and do whatever it do. The problem is just that: how to allow my_custom_predicate to check the url parameters, using it in that way I wrote above.

  • How do I start up an NSRunLoop, and ensure that it has an NSAutoreleasePool that gets emptied?

    - by Nick Forge
    I have a "sync" task that relies on several "sub-tasks", which include asynchronous network operations, but which all require access to a single NSManagedObjectContext. Due to the threading requirements of NSManagedObjectContexts, I need every one of these sub-tasks to execute on the same thread. Due to the amount of processing being done in some of these tasks, I need them to be on a background thread. At the moment, I'm launching a new thread by doing this in my singleton SyncEngine object's -init method: [self performSelectorInBackground:@selector(initializeSyncThread) withObject:nil]; The -initializeSyncThread method looks like this: - (void)initializeSyncThread { self.syncThread = [NSThread currentThread]; self.managedObjectContext = [(MyAppDelegate *)[UIApplication sharedApplication].delegate createManagedObjectContext]; NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; [runLoop run]; } Is this the correct way to start up the NSRunLoop for this thread? Is there a better way to do it? The run loop only needs to handle 'performSelector' sources, and it (and its thread) should be around for the lifetime of the process. When it comes to setting up an NSAutoreleasePool, should I do this by using Run Loop Observers to create the autorelease pool and drain it after every run-through?

  • Splitting EJBs and interfaces into separate module -- deployment fails

    - by Hank
    I'm having trouble following this guide to "extract" my interfaces and entities from my EAR to use them from another Web Application: I use NetBeans 6.8 and Glassfish 3.0.1 "Java Class Library" project contains all the entities and interfaces "Java EE Application" project class library added to the project, is packaged into the EAR contains EJB implementations, MDBs, Test "Java Web Application" project class library added to the project, is packaged into the WAR contains REST interface When I build and deploy the Web Application, all goes well. When I build the JEE application, I can see the jar-file (interfaces, entities) being included. But when I try to deploy the EAR, Glassfish refuses it with a java.lang.NoClassDefFoundError error: [#|2010-03-28T18:25:59.875+0200|WARNING|glassfishv3.0|javax.enterprise.system.tools.deployment.org.glassfish.deployment.common|_ThreadID=28;_ThreadName=Thread-1;|Error in annotation processing: java.lang.NoClassDefFoundError: mvs/core/StoreServiceLocal|#] [#|2010-03-28T18:25:59.876+0200|SEVERE|glassfishv3.0|javax.enterprise.system.core.com.sun.enterprise.v3.server|_ThreadID=28;_ThreadName=Thread-1;|Exception while deploying the app java.lang.IllegalArgumentException: Invalid ejb jar [CoreServer]: it contains zero ejb.

  • The cost of nested methods

    - by Palimondo
    In Scala one might define methods inside other methods. This limits their scope of use to inside of definition block. I use them to improve readability of code that uses several higher-order functions. In contrast to anonymous function literals, this allows me to give them meaningful names before passing them on. For example: class AggregatedPerson extends HashSet[PersonRecord] { def mostFrequentName: String = { type NameCount = (String, Int) def moreFirst(a: NameCount, b: NameCount) = a._2 > b._2 def countOccurrences(nameGroup: (String, List[PersonRecord])) = (nameGroup._1, nameGroup._2.size) iterator.toList.groupBy(_.fullName). map(countOccurrences).iterator.toList. sortWith(moreFirst).head._1 } } Is there any runtime cost because of the nested method definition I should be aware of? Does the answer differ for closures?

  • Override Devise Sign-in with reCaptcha

    - by Bashar Abdullah
    I'm trying to override the Rails devise login to include recaptcha. I followed the steps here http://presentations.royvandewater.com/authentication-with-devise.html#8 however for some reason, authentication always fails. To isolate the problem, I removed all my code and called super directly class SessionsController < Devise::SessionsController def create super end end file is at: Rails.root/app/controllers/sessions_controller.rb the slide suggest Rails.root/app/controllers/sessions.rb but I assume that was just a mistake. Trying it out didn't help either. I even copied the full Sessions Controller code into my own, still gives the problem. Authentication fails here specifically: resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new") Any idea what I might be doing wrong?

  • What is lifetime of lambda-derived implicit functors in C++ ?

    - by Fyodor Soikin
    The question is simple: what is lifetime of that functor object that is automatically generated for me by the C++ compiler when I write a lambda-expression? I did a quick search, but couldn't find a satisfactory answer. In particular, if I pass the lambda somewhere, and it gets remembered there, and then I go out of scope, what's going to happen once my lambda is called later and tries to access my stack-allocated, but no longer alive, captured variables? Or does the compiler prevent such situation in some way? Or what?

  • Exception when programmatically copying content type

    - by BeraCim
    Hi all: I'm getting exceptions when copying content type from one web to another: foreach (SPContentType destinationWebCt in destinationWeb.ContentTypes) { destinationWeb.ContentTypes.Add(existingWebCt); destinationWeb.Update(); } existingWebCt is the content type from another web e.g. /Site/Web. destinationWeb is the web that I wish to copy the content type to e.g. /Site/DestinationWeb. I got the SPException that says something like could not copy content type to scope. Then I decided to replace all "ContentTypes" to "AvailableContentTypes", but then I got the SPException saying this collcetion could not be modified. So how can I copy a content type to another web? Thanks.

  • Why do C compilers prepend underscores to external names?

    - by Michael Burr
    I've been working in C for so long that the fact that compilers typically add an underscore to the start of an extern is just understood... However, another SO question today got me wondering about the real reason why the underscore is added. A wikipedia article claims that a reason is: It was common practice for C compilers to prepend a leading underscore to all external scope program identifiers to avert clashes with contributions from runtime language support I think there's at least a kernel of truth to this, but also it seems to no really answer the question, since if the underscore is added to all externs it won't help much with preventing clashes. Does anyone have good information on the rationale for the leading underscore? Is the added underscore part of the reason that the Unix creat() system call doesn't end with an 'e'? I've heard that early linkers on some platforms had a limit of 6 characters for names. If that's the case, then prepending an underscore to external names would seem to be a downright crazy idea (now I only have 5 characters to play with...).

  • jQuery Plugin Overwriting Parameters

    - by Travis
    Hey Everyone, This maybe a very mundane question, but this is the first jQuery plugin that I write and I'm a bit fuzzy on understanding the scope rules in Javascript. I'm trying to write an simple jQuery plugin that wraps around the Stack Overflow API. I'm starting off by trying to work with the Flair API. I wanted to make the plugin as configurable as possible so that you can easily pass it the domain and user id, and generate multiple Flairs. var superUser = $.jStackOverflow.flair({domain:"superuser.com", id: 30162, parentId:'#su-flair'}); var stackOverflow = $.jStackOverflow.flair({domain:"stackoverflow.com", id: 55954, parentId:'#so-flair'}); The problem is, when it makes the second call, its somehow using the correct domain and id parameters, but the parentId field that it's using in the callback function to create the html, is using the first parameter. You can see the plugin here and the html here

  • Django-allauth redirected to connections

    - by camara90100
    I'm using django-allauth to signup users with Facebook, and I'm setting the ACCOUNT_EMAIL_REQUIRED to True so when a user doesn't have email saved on his account I get redirected to the allauth/templates/socialaccount/Signup.html and when I use a test user to enter a valid email, I get redirect to "connections.html" which then asks me to choose one of the social accounts and remove it. and the form action method is set to 'connections url' so it becomes an infinite loop. anyone knows what's wrong? here's my settings SOCIALACCOUNT_PROVIDERS = \ { 'facebook': { 'SCOPE': ['email', 'publish_stream'], # 'AUTH_PARAMS': { 'auth_type': 'reauthenticate' }, 'METHOD': 'js_sdk' , 'LOCALE_FUNC': lambda request: 'en_US'}} ACCOUNT_EMAIL_REQUIRED =True ACCOUNT_ADAPTER = 'profiles.adapter.MyAccountAdapter' SOCIALACCOUNT_ADAPTER ='profiles.adapter.MySocialAccountAdapter'

  • Block declared variable visible outside?

    If I declare a variable within a block (see below) is there a way to specify that its visible outside the block if need be? if(turbine_RPM > 0) { int intResult = [sensorNumber:1]; NSNumber *result = [NSNumber numberWithInt:intResult]; } return result; or is the way just to declare outside the block scope? NSNumber *result; if(turbine_RPM > 0) { int intResult = [sensorNumber:1]; result = [NSNumber numberWithInt:intResult]; } return result; many thanks gary

  • Do jQuery and JavaScript have different namespaces?

    - by Brett
    I have this code in jQuery.. $(document).ready(function(){ var fieldCounter = 0; ... I have a jQuery function that increments this value. This works, but I can't access this value on the page from a non-jQuery function? The reverse is also true, if I scope it in JavaScript e.g. <script type="text/javascript"> var fieldCounter = 0; I can access it from javascript but jQuery can't view it? I'm probably doing something really dumb?

  • Is it good to use .settings for storing controls text data?

    - by Zenya
    In my WinForms applications I often put the controls text data (form title, labels texts, button captions, etc.) into a .settings (feature automatically generated by Visual Studio - based on the ApplicationSettingsBase class). In particular, Add a form or a control. In Solution Explorer add a new string item into the application scope of the settings file. Bind the control text property with the corresponding item of the settings file (through the property binding). Good point of this is that all my text data is collected in one place and easy to check and edit. Also it is convenient when I want to use the same text for several controls. However, I haven't heard that somebody uses the .settings such way. In tutorials for creating multilingual applications, for example, it is recommended to enter texts directly into the control property. So, is it good practice to use .settings for storing controls text data? Brief conclusion from the answers: Storing controls text data in the .settings is not common practice.

  • making certain cells of an ExtJS GridPanel un-editable

    - by synchronicity
    I currently have a GridPanel with the Ext.ux.RowEditor plugin. Four fields exist in the row editor: port, ip address, subnet and DHCP. If the DHCP field (checkbox) of the selected row is checked, I need to make the other three fields un-editable. I've been trying to perform this code when the beforeedit event is triggered, but to no avail... I've only found ways to make the entire column un-editable. My code so far: this.rowEditor.on({ scope: this, beforeedit: this.checkIfEditable }); checkIfEditable:function(rowEditor, rowIndex) { if(this.getStore().getAt(rowIndex).get('dhcp')) { // this function makes the entire column un-editable: this.getColumnModel().setEditable(2, false); // I want to make only the other three fields of the current row // uneditable. } } Please let me know if any clarification is needed. Any help potentially extending RowEditor to accomplish the target functionality would be greatly appreciated as well!

  • Exchange 2003 Public Folder Replica list

    - by Niall
    Hi, I am trying to update a replica list on a Exchange 2003 public folder. I am using the WMI namespace exchange_publicfolder to try and add an Exchange server (using the servers DN) to the AddReplica procedure. Every time I run this I get an invalid parameter as an exception. Below is the code that I am using to do this. WMI.Connect(Server, credentials) Using WMISearcher As New ManagementObjectSearcher(WMI.Scope, & _ New ObjectQuery(String.Format("SELECT * FROM Exchange_Publicfolder WHERE path='{0}'", Name))) Using PublicFolder As ManagementObjectCollection = WMISearcher.Get For Each Folder As ManagementObject In PublicFolder Dim BaseFolder As ManagementBaseObject = Folder.GetMethodParameters("AddReplica") BaseFolder("path") = ServerDN Folder.InvokeMethod("AddReplica", BaseFolder, Nothing) Next End Using End Using I have used WMI before and I can see that the call is connecting to the correct public folder because i can itterate through the properies once the query has executed. I am not sure what I am doing wrong here. If anyone has any ideas or comments the please let me know. Thanks Niall

  • Is dependency injection possible for JSP beans?

    - by kazanaki
    This may be a long shot question.. I am working on an application that is based on JSP/Javascript only (without a Web framework!) Is there a way to have depencency injection for JSP beans? By jsp beans I mean beans defined like this <jsp:useBean id="cart" scope="session" class="session.Carts" /> Is there a way/library/hack to intercept the bean creation so that when "cart" is referenced for the first time, some some of injection takes place? Can I define somewhere a "listener" for JSP beans (like you can do for JSF beans for example)? I am free to do anything I want in the back-end, but I cannot add a web framework in the front-end (Don't ask!)

  • Need to get back form controls' information externally

    - by Tom
    Are there any tutorials or guides out there that anyone knows of that will show me how to read forms from an external program and get back information about the controls on the form? Currently, I can get the handle to the form, and I can get the class name, but I need to get more information such as a persistent name and contained data. Thanks. Edit: I now have a way to read the contained data (with the WM_GETTEXT message), however, I still need a persistent name/ID that I can be sure will not change from instance to instance. One way I can think of for doing this is to take the handle, find the position of the control on the window, and then get the handle from the position from then on. Another way is to determine a static ID for the control and then use that to get the handle from then on. The new scope of my problem is how to implement either of these. Any Ideas?

  • validates_uniqueness_of with HABTM relationship

    I've got a HABTM relationship between two models: Publication and Author. I want to ensure that one cannot create a publication with the same title, year, and author list. However, if I try something like this: class Publication < ActiveRecord::Base validates_uniqueness_of :title, :scope => [:year, :authors] end This obviously won't work since there is no authors column. Can this be done with validates_uniqueness_of, or do I need a custom validator? Thank you.

  • Simplest way to update a client-side javascript array variable during a ASP.NET AJAX postback in an

    - by Noel
    If I want to inject a globally scoped array variable into a page's client-side javascript during a full page postback, I can use: this.Page.ClientScript.RegisterArrayDeclaration("WorkCalendar", "\"" + date.ToShortDateString() + "\""); to declare and populate a client-side javascript array on the page. Nice and simple. But I want to do the same from a async postback from an UpdatePanel. The closest I can figure so far is to create a .js file that just contains the var declaration, update the file during the async postback, and then use a ScriptManagerProxy.Scripts.Add to add the .js file to the page's global scope. Is there anything simpler? r iz doin it wrong?

  • Why is the modal dialog in MFC actually internally modeless?

    - by pythiyam
    This question arose in my miind after reading this article: http://www.codeproject.com/Articles/3911/The-singular-non-modality-of-MFC-modal-dialogs. He mentions that the modal dialog in MFC is not strictly modal, but implemented as a modeless dialog(internally) with bells and whistles to make it behave as a modal one. Specifically, he says: The MFC command routing mechanism uses a combination of message maps and virtual functions to achieve what it does and a true modal dialog will totally wreck this mechanism because then the modal message loop is controlled outside the scope of the MFC command routing machinery Could anyone elucidate this statement? An example of what would have gone wrong if they had tried to implement a truly modal dialog would greatly clear things up.

  • How does CDI injection work in MDBs and @Scheduled beans?

    - by Nils-Petter Nilsen
    I'm working on a large Java EE 6 application that is deployed on JBoss 6 Final. My current tasks involve using @Inject consistently instead of @EJB, but I'm running into some problems on some types of beans, specifically @MessageDriven beans and beans with @Scheduled methods. What happens is that if I'm unlucky with the timing (for @Schedule) or if there are messages in the MDBs' queues at startup, instantiation of the beans will fail because the injected resources (which are EJBs themselves) are not bound yet. Because I use @Inject, I'm guessing that the EJB container considers my beans to be ready, since the container itself does not care about @Inject; it probably simply assumes that since there are no @EJB injections, the beans are ready for use. The injected CDI proxies will then fail because the resources to inject aren't actually bound yet. Tiny example: @Stateless @LocalBean public class MySupportingBean { public void doSomething() { ... } } @Singleton public class MyScheduledBean { @Inject private MySupportingBean supportingBean; @Schedule(second = "*/1", hour = "*", minute = "*", persistent = false) public void onTimeout() { supportingBean.doSomething(); } } The above example will probably not fail often because there are only two beans, but the project I'm working on binds lots of EJBs, which will amplify the problem. But it might fail because there is no guarantee that MySupportingBean is bound first, and if onTimeout is invoked before MySupportingBean is bound, then instantiation of MyScheduledBean will fail. If I used @EJB instead, MyScheduledBean wouldn't be bound until the dependency to MySupportingBean was satisfied. Note that the example will not fail in onTimeout itself, but when CDI attempts to inject MySupportingBean. I've read a lot of posts on different forums where many people argue that @Inject is always better. Generally, I agree, but how do they handle @Schedule or @MessageDriven combined with @Inject? In my experience, it comes down to dumb luck whether the beans will work or not in those cases, and the beans will fail arbitrarily, depending on which order the EJBs are deployed in, and when @Schedule or onMessage are invoked.
