XML Europe will be returning in Amsterdam this year, from April 18-21 in the RAI Centre. Proposals are due by January 5. I may submit one myself and attend this year for the first time. After all, it's in Amsterdam. :-)
The Big Faceless Organization has released the Big Faceless Report Generator 1.1.12, a $1200 payware Java application for converting XML documents to PDF. Unlike most similar tools it appears to be based on HTML and CSS rather than XSL Formatting Objects. This is mostly a bug fix release. Java 1.2 or later is required.
