Spring Data makes spring unable to find JAXRS's @Provider

[smallufo]

I am using Spring + Jersey to build an API service .
Recently , I try to incorporate Spring Data to my server .
I haven't truly use any Repositories in my running code , just add one line in my app.xml :

<jpa:repositories base-package="destiny.web" entity-manager-factory-ref="entityManagerFactoryApp" />

But ! I notice my API not working , complaining "A message body writer for Java class xxx , and Java type class xxx , and MIME media type application/json was not found"

If I remove the "jpa:repositories ..." line in my xml , everything works fine !
and , all provider classes are registered by spring :

{http://*:8080-1} Registering Spring bean, apiResultJsonWriter, of type destiny.web.api.ApiResultJsonWriter as a provider class
{http://*:8080-1} Registering Spring bean, webApi, of type destiny.web.api.WebApi as a root resource class
{http://*:8080-1} Initiating Jersey application, version 'Jersey: 1.8 06/24/2011 12:17 PM'

But , if I add "jpa:repositories..." line in my XML , only "root resources class" are registered :

{http://*:8080-1} CDI support is enabled
{http://*:8080-1} Using default applicationContext
{http://*:8080-1} Registering Spring bean, webApi, of type destiny.web.api.WebApi as a root resource class
{http://*:8080-1} Initiating Jersey application, version 'Jersey: 1.8 06/24/2011 12:17 PM'

I don't know if it is Spring-Data's bug ?
And how to solve it ?
