Hi everyone,

in case someone else should need it, in the meanwhile I found a solution for suppressing the beep when typing <ENTER> in a readonly (non-editable) JEditorPane:

        editorPane.getActionMap().put("insert-break", new AbstractAction(){      
                        public void actionPerformed(ActionEvent e) {}
                }); //suppress beep on <ENTER> key

So the trick is entering an empty action for 'insert-break' (a funny name for pressing the ENTER key; the other actions have more meaningful names).  Having an empty 'beep' action did not help.
