Hi,
This may be an installation problem.
Did you modify the pom.xml of the samples so that jersey dependencies
are in the scope of provided?
The latter exception is a fundamental error implying something is
wrong with the installation. Do you also get such a ClassCastException
for OneApplication as well, before the NullPointerException when that
application is serviced?
Can you send me the complete log?
It seems that the servlet 3.0 layer may still be utilizing the servlet
even though the initialization failed.
Paul.
