jsf - @Inject-ed value null in @FacesComponent -


i have impression cdi not working classes have @javax.faces.component.facescomponent. true?

here's example, doesn't work. myinjectableclass used @ other points in code injection not problem, must @facescomponent annotation think.

the class want inject:

@named @stateful public class myinjectableclass implements serializable {      private static final long serialversionuid = 4556482219775071397l; }

the component uses class;

@facescomponent(value = "mycomponents.mytag") public class mycomponent extends uicomponentbase implements serializable {      private static final long serialversionuid = -5656806814384095309l;      @inject     protected myinjectableclass injectedinstance;       @override     public void encodebegin(facescontext context) throws ioexception {         /* injectedinstance null here */     } }

unfortunately, jsf 2.2 @facescomponent, @facesvalidator , @facesconverter not valid injection targets (read what's new in jsf 2.2? arjan tijms more details). arjan points out:

it’s taken consideration jsf 2.3 though.

what can now? well, you've got 2 choices:

  1. handle cdi injection via lookup, or switch ejb , simpler ejb lookup;
  2. annotate tour class @named instead of @facescomponent, @inject component way did , register component in faces-config.xml.

and, way, you've got 2 issues you've got far: (1) meant @named @stateful when former cdi world , latter ejb world , (2) sure intend keep state in faces component that's recreated on every request?

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
