Question about FOP 0.94 and 0.20.5

[Juanjo Alejandro]

I try to run in a seem application the two versions of fop 0.94 and
0.20.5.I rebuild version FOP 0.94 changing the names of folders
(org.apache.fop by
org.jcom.fop) and jars to let de ClassLoader upload both librarys. As a
result I get an error of type class not definition found for FopFactory and
another strange errors.
Is it posible to run both versions togheter?


Thanks In advance

Juanjo
