In this case we have default and custom (Jackson) application/json
providers. The custom one has a higher priority.
For more info see sections 4.2.1 and 4.2.2 of the spec:

What is the criteria for preference ?

Question 1) To serialize my domain object containing a hashmap, I am
using
org.apache.cxf.jaxrs.provider.json.JSONProvider but getting this error
"No
message body writer has been found for class java.util.HashMap,
ContentType:
application/json". How can I fix this ?
<jaxrs:server id="restContainer" address="/">
<jaxrs:serviceBeans>
<ref bean="myService" />
</jaxrs:serviceBeans>
<jaxrs:providers>
<bean id="jsonProvider"
class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
<property name="serializeAsArray" value="true" />
</bean>
</jaxrs:providers>
</jaxrs:server>
The default provider only operates on JAXB beans.
Question 2) If I add JacksonProvider in addition to JSONProvider, then
serializing of domain object containing hashmap works fine. My question
here
is when we provide more than one json providers which one does the cxf
container uses ? Is there some preference we can set ?
<jaxrs:server id="restContainer" address="/">
<jaxrs:serviceBeans>
<ref bean="myService" />
</jaxrs:serviceBeans>
<jaxrs:providers>
<bean id="jsonProvider"
class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
<property name="serializeAsArray" value="true" />
</bean>
<bean
class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"/>
</jaxrs:providers>
</jaxrs:server>
The custom provider is preferred by the runtime.
