I am getting warning 

warning: [unchecked] unchecked call to add(E) as a member of the 
raw type java.util.List
    [javac]      listbox.getChildren().add(listaMenu);

where listaMenu is declared as

UISelectItems listaMenu = new UISelectItems();

and listbox is declared as 

HtmlSelectOneListbox listbox = new HtmlSelectOneListbox();

How can I get rid of this warning message when I compile using ant build tasks?

Thanks

Either get a new version of the Faces API implementation you're using (one that supports generics), or put @SuppressWarnings("unchecked") just before the start of the function (right before where public or private would go).

  • I have added as `@SuppressWarnings("unchecked") public HtmlSelectOneListbox myMethod() {` however I am still getting warning message when I compile my project. Thanks – Jacob Oct 21 '12 at 12:23
  • It needs to be applied to every function that makes unchecked calls (ie, add it to each function that's generating warnings, and I expect there'll be quite a few of them). Some IDEs (such as eclipse) may have an option somewhere to auto-add ('quick fix') the suppress warnings annotation. – bdonlan Oct 21 '12 at 12:24

Add an annotation to suppress the warning if the JSF API forces the use of unchecked casting:

@SuppressWarnings(value = "unchecked")

Similar to the answer(s) given here: Java [unchecked] unchecked case warning
