Re: Classpath Problems w/ Camel Based Class In Shared Library

[slew <st...@mauda.freeserve.co.uk>]

I'd like to do something similar, have a custom processor in a shared
library, but hit the same problem.  Is there a way to do this as I don't
want to have to copy/paste the processors everywhere?

Thanks.
