Jason:

available() will return how many bytes you can read without blocking. 
This will always vary.  What you need to do is something like:

Make a new File object from a string that points to the file (it has
to be on the server).

Use File.length() to get the length of the file.

Make a FileInputStream from the File (you may need to cast this to
InputStream to make the Applet happy).

Create a counter var to count bytes read.

while(bytes_read != file_length){
  bytes_read += xxx.read(...); // xxx is the InputStream
  ...
}

By using the counter var you won't stop reading until you've read the
entire file and don't get stuck on shifting values for available().

If you see something that looks like an opinion up there,
it's mine and mine alone.

Mail sent to me from the newsgroups won't bounce but will
