If you have problems with Peter Colpaert's CPYPF2XLS read below,
it could be a help for you.
=================================================

I tried with POI 3.6 and got the same error.
I found the following:
http://community.jaspersoft.com/jasperreports-library/issues/3183-0

<snip>
The deprecated method has been removed into the latest version of POI, 
as of 3-Jan-06 POI now automatically handles Unicode without forcing the 
encoding.
Commenting the affected code line every things work correctly.
</snip>

so I just commended out the lines(6) containing:
setEncoding(cell:1);
recompiled and it worked for me when testing with the QIWS/QCUSTCDT file.
