JSF Composite Component simple Example

Composite components can be better with little generics/reflection applied, after all the purpose is to write once and reuse it.

  • In this example I’ll pass an object to a component and it will print all its fields
  • The component will print only the fields belonging to that class not the ones inherited
  • If you want to get inherited fields use getFields instead of getDeclaredFields
  • How is this useful, in a previous article I showed how to sort a data table with ajax, but that applied only for one class, with this we can do the same for any class we declare
