A little help debugging a JTree

Question

I'm pretty much a first time JTree maker, and I can't seem to find the error in my code keeping me from adding into my categories I was hopeing someone in here would help.
I have a vector containing objects constructed from a text file like so:
try
   *The job of this is to read a file to make items in the
   *categories below.
  fr = new FileReader (myfile);
  br = new BufferedReader (fr);
  line = br.readLine ();
  while (line != null)
   underWho = line;
   name = br.readLine ();
   desc = br.readLine ();
   img = br.readLine ();
   subInfo.addElement (new ProSubTools (underWho, name, desc, img));
   line = br.readLine ();
catch (IOException ioe)
   System.out.println (ioe);
}from here I use the following method to construct my nodes, the first set is made using a String array called categories. ProSubTools is basically a container class so that I can keep info like what node to put them under (underWho), their name and so on.
private void createNodes (DefaultMutableTreeNode top)
  DefaultMutableTreeNode category = null;
  DefaultMutableTreeNode item = null;
  for (int i = 0; i < categories.length; i++)
    category = new DefaultMutableTreeNode (categories );
for (int j = 0; j < subInfo.size (); j++)
{ /*I know the error is in here some where*/
/*This is supposed to make another node for the tree*/
ProSubTools temp = (ProSubTools)subInfo.elementAt (j);
item = new DefaultMutableTreeNode (temp.toString ());
/*fileTo () returns a String saying where to put this node*/
if(temp.fileTo ().equals (categories [i]))
category.add (item);
top.add (category);

Turns out there was nothing wrong, apparently I saved it as my text file as Unicode. sorry
