Jackson Jaxb Json with Apache CXf - json

Question

I am using Jackson Jaxb JSON in my REST project with Apache CXF
JacksonJaxb version . 1.7.0
Apache CXF 2.3.1
I am using following code to return from my method.
#GET
#Consumes({ "application/json", "application/xml", "text/xml" })
#Path("/job/autosuggest")
#Override
public Response getSuggestions(String searchField, Integer resPerPage, String typeCont)
{
List<String> respo = new ArrayList<String>();
respo.add("Atish");
respo.add("Narlawar");
respo.add("India");
return Response.ok(respo).build();
}
Now issue is coming when I compile and run the code on jetty, I get stuck with
DEBUG o.s.b.f.s.DefaultListableBeanFactory [] Finished creating instance of bean 'org.apache.cxf.phase.PhaseManager'
org.codehaus.jackson.map.JsonMappingException: Incompatible types: declared root type ([simple type, class javax.ws.rs.core.Response]) vs java.util.ArrayList
This is not particular to array or wrapper, but any object If I pass rather than String in Response.ok(object) fails to parse.
My configuration is
<util:map id="jsonNamespaceMap" map-class="java.util.Hashtable">
<entry key="http://services.institute.com" value=""/>
<entry key="http://cxf.apache.org/bindings/xformat" value="cxf"/>
</util:map>
<bean id="jsonInputFactory" class="org.codehaus.jettison.mapped.MappedXMLInputFactory">
<constructor-arg ref="jsonNamespaceMap"/>
</bean>
<bean id="jsonOutputFactory" class="org.codehaus.jettison.mapped.MappedXMLOutputFactory">
<constructor-arg ref="jsonNamespaceMap"/>
</bean>
<bean id="jsonProvider" class="org.codehaus.jackson.jaxrs.JacksonJaxbJsonProvider"/>
<jaxrs:server id="jobsearch" address="/">
<jaxrs:serviceBeans>
<ref bean="jobSearchService" />
</jaxrs:serviceBeans>
<jaxrs:extensionMappings>
<entry key="text" value="text/xml"/>
<entry key="xml" value="application/xml"/>
<entry key="json" value="application/json"/>
</jaxrs:extensionMappings>
<jaxrs:languageMappings/>
<jaxrs:properties>
<entry key="javax.xml.stream.XMLInputFactory">
<ref bean="jsonInputFactory"/>
</entry>
<entry key="javax.xml.stream.XMLOutputFactory">
<ref bean="jsonOutputFactory"/>
</entry>
</jaxrs:properties>
<jaxrs:providers>
<ref bean="jsonProvider"/>
</jaxrs:providers>
</jaxrs:server>
</beans>
I am not sure how to proceed on this issue. I already lost 1/2 day to get some workaround. Any help will be appreciated.
Thanks in advance !

Answer 1

At last I got the answer.
The issue is with the version itself.
JacksonJaxb has reported bug in 1.7.0.
I updated the version to higher...in my case it is 1.8.5 and it got fixed.
Hope this helps.
Thanks
