there is a faq-entry at jguru.com (swing faq) which explains how to find 
out where a link points to the mouse clicked at. That's helpful in that 
matter, but it leaves out some tags for some reasons (h3 e.g.). You'd 
have to have an iterator run over all tags like
  Vector elementMap;
    ElementIterator iterator = new ElementIterator(htmldoc);
    while ((element=iterator.next())!=null)
    {
      if (!element.getName().equals("content"))
       {
        System.out.println("Element "+element.getName()+" goes from 
"+Integer.toString(element.getStartOffset()) +" to 
"+Integer.toString(element.getEndOffset()));
        elementMap.add(element);
       }
    }
and then look for 
element[i].getStartOffset<=caretPos&&element[i].getEndOffset>=caretPos.
I haven't tested this but i assume it is quite time-consuming. So either 
you do it only on command or you determine when to rebuild your 
elementmap very good (probably at every change of the document).

good luck
