Using Anchor Component for creating custom anchor tag

[Manoj Dhore]

Hi,

 

 I am trying to create a custom anchor component using
org.apache.struts2.components.Anchor. This is done inside a custom
component that I am creating.
 
Method that initializes Anchor component is as follows :
 

      private void createLink(String action, Containable item, Writer
writer) {

       

 Component a = createAnchor(action, item);

       a.start(writer);

       a.end(writer, item.getName());

        }

 

private Anchor createAnchor(String action, Containable item){

Anchor a = new Anchor(stack, req, resp);

a.setHref(action);

return a;

}
 
However, if my code tries to create a link I get follwing error :
 

java.lang.NullPointerException

Could you please guide me what is the problem with template ? Do I need
to create a custom template or need to set a default template ?

 

Thanks in advance.
