The byteArray is a Java array object, so CF's arrayLen() function would not
work on it. You'd need to use the array's length method like this:
response.setContentLength(byteArray.length());
Java's file class also has a length() method that returns the file size in
bytes.

Does CFFILE have a file size limit?
There is no specific limit on file size for CFFILE. However, CFFILE loads
the file into the server's memory, so you will get an error if the file size
exceeds the amount of free RAM.
Also note,
On a more "personal style" note, I generally do a cfparam on all my form
variables and then loop over the form structure and trim() all the values.
I then do not have to check for existence or trim when checking length.
