Hi Paul,
Thanks for the quick reply and suggestions. I tried using the 1.1.5 version
of the jersey-spring jar along with spring 2.5 and the behavior is still the
same. The spring bean and jersey resource both get instantiated when the
container starts but when I perform a request against the resource they are
instantiated again. So instead of a singleton instance existing, an
instance is created per resource request. The configuration (spring-jersey
jar addition) was what you suggested correct?
