Thomas, Thank you.
I develop xslt files on xp using XMLSpy and fop.bat. But the real application is on Solaris 8 using fop.sh. We actually treat the text as within a text area and we position the text area. In other words, it is just to map html <div> section to <svg:text> section. We thus have problem to use the same x/y coordinates for svg:text section. I really got too many problems with FOP. I think I made wrong decision to use FO approach for a real application. Other small fop errors I got are: (1) if the table cell width is too small, fop crash (2) if the number table columns used is greater than the number of columns defined, FOP stops with ERROR: NULL on XP and ERROR: -2 on Solaris, but without real error reason. Sorry I keep bothering you guys. And thank you for always response to my emails.
