After being unsuccessful at my effort to make the above route to work, I
created the necessary inbox and outbox folders and my new route looks like
below:
from("file://Users/jothi/Desktop/inbox/filename=my.xml").unmarshal(jaxb).bean(new
ProcessorBean()).to("file://Users/jothi/Desktop/inbox/filename=my.xml");
Why does this not work either? What else should I tell Camel so that he
writes the my.xml to the outbox?
Regards,
Jothi
