  • Java, let CookieHandler work on only one instance.

    - by user435657
    Hi all, I don't know how CookieHandler works system wide, I did view the source of CookieHandler but found no more information except the get/set methods. Where do TCP/HTTP connections use instance of CookieHandler, which I set by CookieHandler.setDefault(...) Which source file I should refer to? URLConnection & HttpURLConnection don't seem have things to do with it. Help, thanks in advance.

  • Is there a way to detect non-movement (touch events) ?

    - by hyn
    Is there a way to detect a finger's non-movement by using a combination of UITouch events? The event methods touchesEnded and touchesCancelled are only fired when the event is cancelled or the finger lifted. I would like to know when a touch has stopped moving, even while it is still touching the screen.

  • Is there a way to know when the index on uitableview is actually used?

    - by NoviceiPhoneProgrammer
    Is there a way to know when the index on uitableview is actually used? I can’t find any methods in the Apple documentation, but I was wondering if anyone else knows anything. I would basically like to make an animation in my table view that changes depending on what section is selected in the index, and I have no idea how to do this without accessing the table view index. Any help is greatly appreciated. Thanks.

  • Hibernate/Spring: getHibernateTemplate().save(...) Freezes/Hangs

    - by ashes999
    I'm using Hibernate and Spring with the DAO pattern (all Hibernate dependencies in a *DAO.java class). I have nine unit tests (JUnit) which create some business objects, save them, and perform operations on them; the objects are in a hash (so I'm reusing the same objects all the time). My JUnit setup method calls my DAO.deleteAllObjects() method which calls getSession().createSQLQuery("DELETE FROM <tablename>").executeUpdate() for my business object table (just one). One of my unit tests (#8/9) freezes. I presumed it was a database deadlock, because the Hibernate log file shows my delete statement last. However, debugging showed that it's simply HibernateTemplate.save(someObject) that's freezing. (Eclipse shows that it's freezing on HibernateTemplate.save(Object), line 694.) Also interesting to note is that running this test by itself (not in the suite of 9 tests) doesn't cause any problems. How on earth do I troubleshoot and fix this? Also, I'm using @Entity annotations, if that matters. Edit: I removed reuse of my business objects (use unique objects in every method) -- didn't make a difference (still freezes). Edit: This started trickling into other tests, too (can't run more than one test class without getting something freezing) Transaction configuration: <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <tx:advice id="txAdvice" transaction-manager="txManager"> <!-- the transactional semantics... --> <tx:attributes> <!-- all methods starting with 'get' are read-only --> <tx:method name="get*" read-only="true" /> <tx:method name="find*" read-only="true" /> <!-- other methods use the default transaction settings (see below) --> <tx:method name="*" /> </tx:attributes> </tx:advice> <!-- my bean which is exhibiting the hanging behavior --> <aop:config> <aop:pointcut id="beanNameHere" expression="execution(* com.blah.blah.IMyDAO.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="beanNameHere" /> </aop:config>

  • Is this a problem typically solved with IOC?

    - by Dirk
    My current application allows users to define custom web forms through a set of admin screens. it's essentially an EAV type application. As such, I can't hard code HTML or ASP.NET markup to render a given page. Instead, the UI requests an instance of a Form object from the service layer, which in turn constructs one using a several RDMBS tables. Form contains the kind of classes you would expect to see in such a context: Form= IEnumerable<FormSections>=IEnumerable<FormFields> Here's what the service layer looks like: public class MyFormService: IFormService{ public Form OpenForm(int formId){ //construct and return a concrete implementation of Form } } Everything works splendidly (for a while). The UI is none the wiser about what sections/fields exist in a given form: It happily renders the Form object it receives into a functional ASP.NET page. A few weeks later, I get a new requirement from the business: When viewing a non-editable (i.e. read-only) versions of a form, certain field values should be merged together and other contrived/calculated fields should are added. No problem I say. Simply amend my service class so that its methods are more explicit: public class MyFormService: IFormService{ public Form OpenFormForEditing(int formId){ //construct and return a concrete implementation of Form } public Form OpenFormForViewing(int formId){ //construct and a concrete implementation of Form //apply additional transformations to the form } } Again everything works great and balance has been restored to the force. The UI continues to be agnostic as to what is in the Form, and our separation of concerns is achieved. Only a few short weeks later, however, the business puts out a new requirement: in certain scenarios, we should apply only some of the form transformations I referenced above. At this point, it feels like the "explicit method" approach has reached a dead end, unless I want to end up with an explosion of methods (OpenFormViewingScenario1, OpenFormViewingScenario2, etc). Instead, I introduce another level of indirection: public interface IFormViewCreator{ void CreateView(Form form); } public class MyFormService: IFormService{ public Form OpenFormForEditing(int formId){ //construct and return a concrete implementation of Form } public Form OpenFormForViewing(int formId, IFormViewCreator formViewCreator){ //construct a concrete implementation of Form //apply transformations to the dynamic field list return formViewCreator.CreateView(form); } } On the surface, this seems like acceptable approach and yet there is a certain smell. Namely, the UI, which had been living in ignorant bliss about the implementation details of OpenFormForViewing, must possess knowledge of and create an instance of IFormViewCreator. My questions are twofold: Is there a better way to achieve the composability I'm after? (perhaps by using an IoC container or a home rolled factory to create the concrete IFormViewCreator)? Did I fundamentally screw up the abstraction here?

  • JSF action, value and binding catalog generator

    - by BBSnowman
    I am looking for a simple tool that generates a catalog of all used action methods, values and bindings. I'm working on a big JSF/RichFaces project and I have lost the overview of the used links to the beans. Therefore I need a tool (would be nice if it is a Eclipse plugin) that generates a simple list of all used EL expressions. Is there something out there?

  • Method parameters confusion

    - by elec
    Often time methods take more than 3 parameters which are all of the same type, eg. void mymethod (String param1, String param2, String param3) then it's very easy for the client to mix up the parameters orders, for instance inverting param1 and param2: mymethod (param2, param1, param3); ...which can be the cause of much time spent debugging what should be a trivial matter. Any tips on how to avoid this sort of mistake (apart from unit tests) ?

  • Navigating to rootViewController of non-visible UINavigationController CRASH

    - by Bertie
    First off I'n not sure if this is exactly the issue... but it appears to be central to the problem. There are vast gaps in what I know and this may be something very obvious. I have a split view controller with various Master and Detail Views. From one 'menu' branch I want to return to the rootView of both the Master & Detail Navigation Controllers when the user taps a 'Done' button. Initially I had the button positioned on the navigation bar of the master view. This is the code I was using: - (IBAction)doneClicked:(id)sender { UINavigationController *detailNav = [self.splitViewController.viewControllers objectAtIndex:1]; NSArray *allDetailViewControllers = detailNav.viewControllers; HomePage *destinationDetailVC = [allDetailViewControllers objectAtIndex:0]; destinationDetailVC.splitViewBarButtonItem = self.splitViewButton; [detailNav popToRootViewControllerAnimated:NO]; [self.navigationController popToRootViewControllerAnimated:NO]; } That works fine but if the device is in portrait mode it means the user has to open the menus to access the button. So I decided to put the 'Done' button onto the detail view NavBar instead. Using a delegate declared in the detailVC and adopted by the masterVC I am now using this method: - (void)theUserClickedDoneInTheDetailView:(DetailVC *)controller withButton:(UIBarButtonItem *)splitViewButton { UINavigationController *detailNav = [self.splitViewController.viewControllers objectAtIndex:1]; NSArray *allDetailViewControllers = detailNav.viewControllers; HomePage *destinationDetailVC = [allDetailViewControllers objectAtIndex:0]; destinationDetailVC.splitViewBarButtonItem = splitViewButton; [detailNav popToRootViewControllerAnimated: NO]; [self.navigationController popToRootViewControllerAnimated:NO]; } Both methods are in the MasterVC.m file The only difference between the two is that on is passed a UIBarButtonItem to use and the other has already had it passed when it is set in the detail view. That seems to be working because I do get a button. When the device is in Landscape mode both methods work fine. All behaviour as expected. When the device is in Portrait the first method still works fine. The second appears to work fine and the detail view is the rootView, the button for the menus is there BUT, as soon as I turn the device to landscape it crashes. The only thing I can think of is that it is because the masterView is hidden. Can anyone help...?

  • How do I fix my Unit Test to have global access to everything?

    - by SLC
    Usually when you add one (in Visual Basic), it pops up a message asking if you want to enable an option that lets the test access things like private methods etc. However, I am editing a solution that does not have this enabled. I'd like to enable it so my unit tests will work, but I can't find the setting. Can anyone tell me how to enable it after the project has been created?

  • can I have an abstract base class with the key attribute being generic

    - by Greg
    Hi, I want to create a re-usable library. I was going to use extension methods however I run into some issues in some cases for the client to have to specify in the calling method the types. QUESTION - If I use an abstract base class as the basis, can I specify an attribute/property in the class to be generic (e.g. the key property might be an 'int' in one case, or a 'string' in another)?

  • Perl Regular Expression [] for <>

    - by bmucklow
    So I am trying to read an XML file into a string in Perl and send it as part of a SOAP message. I know this is not ideal as there are methods for SOAP sending files, however, I am limited to having to use the SOAP that is set up, and it is not set up for sending with file support. Therefore I need to parse out the markup tags < and replace them with []. What is the best way to do this?

  • declerative_authorization on User problem

    - by Webpain
    I am trying to block all default methods except create and update in my users controller using declerative_authorization. But at the time I add filter_resource_access or filter_access_to into my usersController i always get "Couldn't find User without an ID". Anyone care to explain why this could be happening? class UsersController :new end end def show @user = @current_user end def edit @user = @current_user end def update @user = @current_user # makes our views "cleaner" and more consistent if @user.update_attributes(params[:user]) flash[:notice] = "Account updated!" redirect_to account_url else render :action = :edit end end end
