Hi,
What is the following class doing:
yjava.ws.util.jaxb.JAXBContextWrapper
? can you share the code ? (feel free to send me it privately if you
do not want to send to the public list).
Do you have a ContextResolver<JAXBContext> in your application ?
I am wondering if you compiled some Java source using Jersey 1.1.0-ea
and are reusing those classes with Jersey 1.1.1-ea. For 1.1.1-ea we
refactored the JSON JAXB code to make it reusable, thus the class
com.sun.jersey.json.impl.JSONUnmarshaller was refactored to become
com.sun.jersey.api.json.JSONUnmarshaller:
https://jersey.dev.java.net/nonav/apidocs/1.1.1-ea/jersey/com/sun/jersey/api/json/JSONUnmarshaller.html
https://jersey.dev.java.net/nonav/apidocs/1.1.1-ea/jersey/com/sun/jersey/api/json/JSONJAXBContext.html
