Hi David,
Can you send me:
1) the log output from the server including the the complete exception
stack trace; and
3) the code of the resource method that returns the JAXB artifacts.
Even better would be a simple maven project that reproduces the error
(send me privately if you like).
Just adding OurResolver to your application with nothing else changing
should not result in the type of error you are observing, so i need to
understand what your complete application is.
Paul.
