Oracle Forms

Hi,
My requirement is to generate a CSV file(or .XLS) on the client machine ie local drive with the details shown in a form.
Oracle version -
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0 - Production
CORE 11.1.0.7.0 Production
TNS for Solaris: Version 11.1.0.7.0 - Production
NLSRTL Version 11.1.0.7.0 - Production.

I have searched the web for last couple of days and got to know that TEXT_IO is to be used to generate files on client machine. However, when I tried TEXT_IO, it was not able to generate the file on client rather it was able to generate on database server. After further browsing on this, there was a link which said that we need to use CLIENT_TEXT_IO to generate file on client side. For this, i was required to subclass the webutil.pll which i did and corrected the code to use CLIENT_TEXT_IO. The form was unable to compile and was not able to find "webutil_core" package.
I am very confused with the disparity in the information available on the web as in what to use to generate a file on client side. If anyone has use it in the past, can he/she please detail what to use to get things sorted.

Thanks,
R
