If you are looking for a tool to create PDF files on the fly, and are not looking to spend alot of money, consider using Crystal.Net.
It comes with Visual Studio and allows you to make reports exportable to PDF in a relatively easy process.
You can read more about this on Microsoft's site:

Hello David,

In Visual Studio .net, there is a report design feature that will allow you to create reports for use in your Visual Studio .NET applications. You can use you application as a thick-client application which means that all report processing for the application occurs on the computer of the end user and not on the server. Once you create the PDF report, you can save it on your website for users to view.

.NET is also compatible with the Crystal Reports server but that needs installation on the server side.

Good Luck

David,

Coldfusion also offers a way to create PDF files on the fly using the cfcontent tag. You can find more information on this tag at:

Since you are running Coldfusion 5 on our servers you would have to use the cfcontent workaround, its almost the same as using the tag itself. You can find the workaround at this link:

The Mime type for PDF is "application/PDF"

I hope that helps.\
