Hi,
I tried the option you had suggested(switched the "addProvider" and
recompiled FOP...I also tried with imt.addProvider(jpegImageIOImage)
commented). Didn't make any difference.
Yes. I have only one page-sequence and i use with "page x of y".
I use fo:external-graphic and i use a servlet to pipe my image thats stored
as BLOB in my DB.
Do i have any other options to either clear the image files OR prevent FOP
from creating these tmp files?
Appreciate your help.
Regards,
John
