You can only cast an Object[] to a Hashtable[] if the array was originally
made at a Hashtable[] (Or something to that effect, I read it in the JDC
forums)
To do what you want to do, add code to the following effect at the end of
your method:
Hastable[] hashArray = new Hashtable[stuff.size()];
stuff.copyInto(hashArray);
return hashArray;
Good luck,
