java - Passing date input when invoking via cxf jaxrs:client -

maybe trivial, somehow have not been able around finding why doesn't work!

i have service exposed via cxf's jaxrs:server directive

<jaxrs:server id="specialservicers"     address="http://localhost:8080/specialservicers">     <jaxrs:servicebeans>         <ref bean="specialservice" />     </jaxrs:servicebeans>     <jaxrs:providers>         <bean id="jaxbprovider"             class="org.apache.cxf.jaxrs.provider.jaxbelementprovider">             <property name="marshallasjaxbelement" value="true" />             <property name="unmarshallasjaxbelement" value="true" />         </bean>         <bean class="org.codehaus.jackson.jaxrs.jacksonjsonprovider">             <property name="mapper" ref="jacksonmapper" />         </bean>         <bean class="com.kilo.progressivedatehandler" />     </jaxrs:providers> </jaxrs:server> <bean id="jacksonmapper" class="org.codehaus.jackson.map.objectmapper">     <property name="serializationconfig.dateformat">         <bean class="java.text.simpledateformat">             <constructor-arg value="yyyymmddhh:mm:ss.s" />         </bean>     </property>     <property name="deserializationconfig.dateformat">         <bean class="java.text.simpledateformat">             <constructor-arg value="yyyymmddhh:mm:ss.s" />         </bean>     </property> </bean> 

to able handle dates correctly, added date handler - progressivedatehandler - parameterhandler , paramconverter. seems work fine when invoked via browser - when invoked via java based client configured via cxf's jaxrs:client directive,

<jaxrs:client id="specialserviceclient" serviceclass="com.kilo.specialserviceimpl"     address="http://localhost:8080/specialservicers">     <jaxrs:providers>         <bean class="org.codehaus.jackson.jaxrs.jacksonjsonprovider">             <property name="mapper" ref="jacksonmapper" />         </bean>         <bean class="com.kilo.progressivedatehandler" />     </jaxrs:providers> </jaxrs:client> <bean id="jacksonmapper" class="org.codehaus.jackson.map.objectmapper"> </bean> 

i following error:

on further debugging, looks using org.apache.cxf.jaxrs.provider.providerfactory$legacyparamconverter instead of paramconverter viz. progressivedatehandler. appreciate if point out going wrong - have configured incorrectly, because thisseems advertised working out of box when configuring handler.

thanks in advance!

p.s.: have test setup if wants see in action.

looks correct way use paramconverter implement paramconverterprovider interface indicated here.

@suppresswarnings("unchecked") @override public <t> paramconverter<t> getconverter(class<t> rawtype,         type generictype, annotation[] annotations) {     if (rawtype == date.class) {         return (paramconverter<t>) this;     }     return null; } 

not warming concept of 2 interfaces helping in achieving same thing sergey said on jsr-339 mailing list - got follow specs! :)

that seems rid of error - hope helps else well. also, if taking incorrect route, feel free correct me. thanks!
