Could PlainDocument set Foreground Color Attribute?

Question

PlainDocument class has a method called
insertString(int pos,String str,AttributeSet a)
It looks like we could add attributes to PlainDocument ,but
when I assign it a Attribute Set ,the foreground color doesn't
change, could anyone tell me how to change attributes
in PlainDocument?
Thanks a lot!

Yes, I tried these two already,but it still doesn,t work.
I found whether I use JEditorPane or JTextPane ,it does not change anything.
In the subclass of the JEditorPane ,called SubEditorPane, I write the code
setContentType("text/plain"); -->to get the DefaultEditor instance for SubEditorPane
PlainDocument doc = (PlainDocument)getEditorKit().createDefaultDocument();
-->to get PlainDocument instance
then I use doc.insertString(0,"This is a Test Words",style);
where the style is a NamedStyle instance :
StyleContext sct = new StyleContext();
Style style = sct.addStyle("test",null);
style.addAttribute(StyleConstants.Foreground,Color.blue);
But it doesn't change anything :foreground color is still black!!
I don't know where I do the wrong thing ,style instance or else ?
Thanks!
