thnaks for the help - it works. Only problem:
if connection to toUri fails, MyErrorhandler is
invoked; but if connection to fromUri fails,
MyErrorHandler not invoked!
for example,
from("file://a.log").onException(Exception.class).process(MyErrHandler).to("ftp://u...@server?....";).end()
is working if I cant connect to ftp server; but
from("ftp://u...@server?....";).onException(Exception.class).process(MyErrHandler).to("file://a.log").end()
not invoking MyErrHandler if server not online.
why this difference in behavior?
