While testing the DataApp Sample with NetBeans 7.1 RC1, and JavaFX 2.0.2, we ran into the following error.
This same error occurs either:
1) When trying to build DataAppPreloader, which has a preloader.css file. Since I'm building with NB 7.1. RC1, I also
create new NB projects for all of the DataApp sample, including DataAppPreloader and DataAppServer.
2) When trying to run DataAppServer in this same environment. Since DataApp is an end-to-end solution that has both
a JavaFX client and server code that runs on Glassfish, "run" implies deployment to the Glassfish server.

The error message is(note: the CSS conversion error msg and stacktrace exist, regardless of the "msvcr100.dll" msg):
