17.7.2. Possible Problems with Jettison Provider
If you have the
resteasy-jackson-provider-xxx.jar
in your classpath, the Jackson JSON provider will be triggered. This is problematic for code that depends upon the Jettison JAXB or JSON provider. To correct this, you must either remove Jackson from your WEB-INF/lib
or classpath, or use the @NoJackson
annotation on your JAXB classes.
