Thanks for the pointer. I made the necessary changes to my route but still
unable to make it work!
from("file:.?fileName=my.xml").unmarshal(jaxb).bean(new
ProcessorBean()).to("file:.?fileName=my1.xml");
For convenient sake, I changed the name of the target file (my1.xml). Why
would my ProcessorBean not invoked? Also how can I see that my.xml was
picked up by Camel in the from clause?
Regards,
Jothi
