  • Cannot get principal id on my Spock test

    - by Ant's
    I have a controller like this : @Secured(['ROLE_USER','IS_AUTHENTICATED_FULLY']) def userprofile(){ def user = User.get(springSecurityService.principal.id) params.id = user.id redirect (action : "show", params:params) } I want to test the controller above controller in spock, so I wrote a test code like this: def 'userProfile test'() { setup: mockDomain(User,[new User(username:"amtoasd",password:"blahblah")]) when: controller.userprofile() then: response.redirectUrl == "/user/show/1" } When I run my test, this test fails with this error message : java.lang.NullPointerException: Cannot get property 'principal' on null object at mnm.schedule.UserController.userprofile(UserController.groovy:33) And in case of Integration test: class UserSpec extends IntegrationSpec { def springSecurityService def 'userProfile test'() { setup: def userInstance = new User(username:"antoaravinth",password:"secrets").save() def userInstance2 = new User(username:"antoaravinthas",password:"secrets").save() def usercontroller = new UserController() usercontroller.springSecurityService = springSecurityService when: usercontroller.userprofile() then: response.redirectUrl == "/user/sho" } } I get the same error as well. What went wrong? Thanks in advance.

  • Java Thread Message Passing

    - by pkulak
    I'm writing an Android app. I have a main method, which creates and runs a new Thread using an anonymous inner Runnable class. The run() method, when it's done, calls a method on it's parent class (in the main thread) that calls notifyDataSetChanged() so that the main thread can redraw the new data. This is causing all kinds of trouble (ViewRoot$CalledFromWrongThreadException). The thing is, this method being called from the worker thread is on the class that's created in the UI thread. Shouldn't that be running on the UI thread? Or am I missing something? Here's some code about what I'm talking about: public class Mealfire extends Activity { @Override public void onCreate(Bundle icicle) { (new Thread() { public void run() { // Do a bunch of slow network stuff. update(); } }).start(); } private void update() { myAdapter.notifyDatasetChanged(); } }

  • Java Inheritance Concept Understanding

    - by Nirmal
    Hello All.... I am just refreshing the oops features of the java. So, I have a little confusion regarding inheritance concept. For that I have a following sample code : class Super{ int index = 5; public void printVal(){ System.out.println("Super"); } } class Sub extends Super{ int index = 2; public void printVal(){ System.out.println("Sub"); } } public class Runner { public static void main(String args[]){ Super sup = new Sub(); System.out.println(sup.index+","); sup.printVal(); } } Now above code is giving me output as : 5,Sub. Here, we are overriding printVal() method, so that is understandable that it is accessing child class method only. But I could not understand why it's accessing the value of x from Super class... Thanks in advance....

  • Guice child injector override binding

    - by Roman
    Hi All I am trying to to override a binding in a child injector that was already configured in a base injector. like that : public class PersistenceModule extends Abstract{ @Override protected void configure() { bind(IProductPersistenceHelper.class).to(ProductPersistenceHelper.class); } } then : Injector injector = Guice.createInjector(new PersistenceModule()); injector.createChildInjector(new AbstractModule(){ @Override protected void configure() { bind(IProductPersistenceHelper.class).to(MockProductPersistenceHelper.class); } }) Guice is complaining that it has already a binding for that. Are there any patterns or best practices for that problem ?

  • afterTransactionCompletion not working

    - by Attilah
    I created an hibernate interceptor : public class MyInterceptor extends EmptyInterceptor { private boolean isCanal=false; public boolean onSave(Object entity, Serializable arg1, Object[] arg2, String[] arg3, Type[] arg4) throws CallbackException { for(int i=0;i<100;i++){ System.out.println("Inside MyInterceptor(onSave) : "+entity.toString()); } if(entity instanceof Canal){ isCanal=true; } return false; } public void afterTransactionCompletion(Transaction tx){ if(tx.wasCommitted()&&(isCanal)){ for(int i=0;i<100;i++){ System.out.println("Inside MyInterceptor(afterTransactionCompletion) : Canal was saved to DB."); } } } but the method afterTransactionCompletion doesn't get executed after a transaction is commited. I've tried all the ways I know of but I can't make it work. What's more surprising is that the onSave method works fine. Help ! Could this be due to this bug ? : http://opensource.atlassian.com/projects/hibernate/browse/HHH-1956 How can I circumvent this bug if it's the cause ?

  • android thread management onPause

    - by Kwan Cheng
    I have a class that extends the Thread class and has its run method implemented as so. public void run(){ while(!terminate){ if(paused){ Thread.yield(); }else{ accummulator++; } } } This thread is spawned from the onCreate method. When my UI is hidden (when the Home key is pressed) my onPause method will set the paused flag to true and yield the tread. However in the DDMS I still see the uTime of the thread accumulate and its state as "running". So my question is. What is the proper way to stop the thread so that it does not use up CPU time?

  • What's the purpuse behind wildcards and how are they different from generics?

    - by Nazgulled
    Hi, I never heard about wildcars until a few days ago and after reading my teacher's Java book, I'm still not sure about what's it for and wwhy would I need to use it. Let's say I have a super class Animal and few sub classes like Dog, Cat, Parrot, etc... Now I need to have a list of animals, my first thought would be something like: List<Animal> listAnimals Instead, my colleagues are recommending something like: List<? extends Animal> listAnimals Why should I use wildcards instead of simple generics? Let's say I need to have a get/set method, should I use the former or the later? How are they so different?

  • null pointer exception on list.add

    - by Eric
    I've been working on this one error for a few hours so I thought I'd pick the brains of some pros. I am getting a null pointer exception at the modelData.add(i, es) method. I know from debugging that es isn't null. I'm really confused, thanks. public class EventTableModel extends AbstractTableModel { //private int rowCount = 0; protected List<EventSeat> modelData; private static final int COLUMN_COUNT = 3; private Event e; Event j = GUIpos.m; int i = 1; public EventTableModel(Event e) { this.e = e; try { System.out.println(modelData); for (EventSeat es : e.getEventSeats()) { modelData.add(i, es); i++; } } catch (DataException ex) { Logger.getLogger(EventTableModel.class.getName()).log(Level.SEVERE, null, ex); } }

  • Validation of method parameters

    - by Anton Tsivarev
    I have a RESTful web service. For implementation using JAX-RS (Jersey). Have the following method: public void foo (@PathParam ("name") String uuid) { ... } I need to do validation of input parameters. And if data invalid throw WebApplicationException. I added my custom annotation CheckUuid (extends ): public void foo (@PathParam ("name") @CheckUuid String uuid) { ... } Is it possible to do validation using annotations on a stage when the method chosen, but not yet called? For example using PreProcessInterceptor?

  • ImageView Force closes my application

    - by BlueFireLady
    Hi there I am really a beginner, and I have been fighting with this problem for 3 days. :( I am able to get an image to show using a grid view and an adapter as in the grid view tutorial, but I wanted to be able to just use ImageView in the xml. public class HelloImage extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView gridview = (ImageView) findViewById(R.id.gridview); gridview.setLayoutParams(new GridView.LayoutParams(85, 85)); gridview.setScaleType(ImageView.ScaleType.CENTER_CROP); gridview.setPadding(8, 8, 8, 8); gridview.setImageResource(R.drawable.hand_tool); } } When I run this it causes the app to force close when loading.

  • Nested Dynamic PHP Class

    - by user338844
    Alright, I may just need a terminology update, but I have been playing in Magento and Joomla, and they do references like $mage = new Mage; $mage->block('blockname'); where class Mage through some process I am failing to figure out is calling: class blockname extends something{ } Don't quote me on that code, however I am looking to do something like that where I have a file that I can do $myscript-block('blockname'); and it will load and call the file with class blockname. I hope that is not too confusing, but any help is appreciated. Thanks in advance!

  • Click Listener not invoked within ListFragment

    - by membersound
    I'm extending a SherlockListFragment, but it should not matter as my question seems to be more general related to Fragments. Now, I implement a simple click listener for my list, but it does not get called. public class MyListFragment extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.list, container, false); v.setOnClickListener(new OnClickListener() { public void onClick(View view) { Log.i("debug", "single click"); } }); return v; } } Is anything wrong with this? //Solution: listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.i("debug", "single click"); } });

  • Overload and hide methods in Java

    - by Marco
    Hi, i have an abstract class BaseClass with a public insert() method: public abstract class BaseClass { public void insert(Object object) { // Do something } } which is extended by many other classes. For some of those classes, however, the insert() method must have additional parameters, so that they instead of overriding it I overload the method of the base class with the parameters required, for example: public class SampleClass extends BaseClass { public void insert(Object object, Long param){ // Do Something } } Now, if i instantiate the SampleClass class, i have two insert() methods: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object); sampleClass.insert(Object object, Long param); what i'd like to do is to hide the insert() method defined in the base class, so that just the overload would be visible: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object, Long param); Could this be done in OOP?

  • How can I send Data from BroadcastReceiver to Widget?

    - by Yverman
    I have a BroadcastReceiver which loads data from the Internet and then it should send them back to a Widget. But how can I do this? What I've already done is updating the Widget directly from the Broadcast, but I like to just send de data back. public class UpdateManager extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); ComponentName thisWidget = new ComponentName(context, Widget.class); remoteViews.setTextViewText(R.id.widget_textview, "UPDATE DONE"); appWidgetManager.updateAppWidget(thisWidget, remoteViews); } }

  • PHP: How do I access child properties from a method in a base object?

    - by Nick
    I'd like for all of my objects to be able to return a JSON string of themselves. So I created a base class for all of my objects to extend, with an AsJSON() method: class BaseObject { public function AsJSON() { $JSON=array(); foreach ($this as $key = $value) { if(is_null($value)) continue; $JSON[$key] = $value; } return json_encode($JSON); } } And then extend my child classes from that: class Package extends BaseObject { ... } So in my code, I expect to do this: $Box = new Package; $Box-SetID('123'); $Box-SetName('12x8x6'); $Box-SetBoxX('12'); $Box-SetBoxY('8'); $Box-SetBoxZ('6'); echo $Box-AsJSON(); But the JSON string it returns only contains the BaseClass's properties, not the child properties. How do I modify my AsJSON() function so that $this refers to the child's properties, not the parent's?

  • Can a plain servlet be configured as a seam component?

    - by stacker
    I created a plain servlet within a seam-gen (2.1.2) application, now I would like to use injection. Thus I annotated it with @Name and it's recognized as component: INFO [Component] Component: ConfigReport, scope: EVENT, type: JAVA_BEAN, class: com.mycompany.servlet.ConfigReport Unfortunatly the injection of the logger doesn't work NullPointerException in init() import org.jboss.seam.annotations.Logger; import org.jboss.seam.annotations.Name; import org.jboss.seam.log.Log; @Name("ConfigReport") public class ConfigReport extends HttpServlet { @Logger private Log log; public void init(ServletConfig config) throws ServletException { log.info( "BOOM" ); } } Is my approach abusive? What would be the alternatives (the client sending requests to the servlet is curl, not a browser)?
