Hi Dan, Angelo Having references to beans is also supported in DOSGI CXF 1.3,
Please see the example from Jeff at the very top here: http://cxf.547215.n5.nabble.com/Custom-interceptors-with-DOSGi-td5143924.html#a5152563 The same should would for rs providers Angelo, can you try it please ? Thanks, Sergey On 19/03/12 15:49, Daniel Kulp wrote:
For (1), you may be able to just add @XmlSeeAlso annotation onto the the @Page class to point at the various other types. When working with subclasses in JAXB, you have to do the same thing to let JAXB know about the potential subclasses and such. Thus, that alone may fix that issue. Not really sure though. (2) sounds like a potential enhancement. Patches are more than welcome. :-) Dan On Sunday, March 18, 2012 12:52:15 PM Angelo zerr wrote:Hi CXF Team, I have a problem with JAXBContext with type of class MyClass<T>. When I have MyClass<MySecondClass>, JAXBContext is poupulated with only MyClass and not with MySecondClass. I have resolved my problem, but I find it's not a clean solution. Let's me explain more my case. I have a service wich uses Spring Data Page+Pageable (to manage pagination with Spring Data JPA) in OSGi context : -------------------------------------------------------------------------- ---------------------------------------------- package org.akrogen.services; import org.akrogen.domain.User; import org.springframework.data.domain.Page; import org.springframework.data.domain.Pageable; public interface UserService { Page<User> findAll(Pageable pageable); } -------------------------------------------------------------------------- ---------------------------------------------- I wish call this services with remoting by using DOSGi with REST (I'm using JSONProvider). So I have created XmlAdapter for Spring Data Page+Pageable + add REST annotations : -------------------------------------------------------------------------- ---------------------------------------------- package org.akrogen.services; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter; import org.akrogen.domain.User; import org.akrogen.services.adapater.PageXmlAdapter; import org.akrogen.services.adapater.PageableXmlAdapter; import org.springframework.data.domain.Page; import org.springframework.data.domain.Pageable; @Path("/user") public interface UserService { @GET @Path("/findAll/{pageable}") @Produces("application/json") @XmlJavaTypeAdapter(PageXmlAdapter.class) Page<User> findAll(@XmlJavaTypeAdapter(PageableXmlAdapter.class) @PathParam("pageable") Pageable pageable); } -------------------------------------------------------------------------- ---------------------------------------------- To export my service (with REST) I use DOSGi : -------------------------------------------------------------------------- ----------------------------------------------<osgi:reference id="userService" interface="org.akrogen.services.UserService" /> <osgi:service interface="org.akrogen.services.UserService"> <osgi:service-properties> <entry key="service.exported.interfaces" value="*" /> <entry key="service.exported.configs" value="org.apache.cxf.rs" /> <entry key="service.exported.intents" value="HTTP" /> <entry key="org.apache.cxf.rs.address" value=" http://localhost:9090/a"; /> <entry key="org.apache.cxf.rs.databinding" value="jaxb" /> </osgi:service-properties> <ref bean="userService" /> </osgi:service> -------------------------------------------------------------------------- ---------------------------------------------- So the provider used is the default Jettison JSONProvider. When I access to my service I have this error : -------------------------------------------------------------------------- ---------------------------------------------- JAXBException occurred : class org.akrogen.domain.User nor any of its super class is known to this context.. class org.akrogen.domain.User nor any of its super class is known to this context.. -------------------------------------------------------------------------- ---------------------------------------------- Which means that JAXBContext is not populate with User class. To resolve my problem, I has to create My own JSONProvider wich add extra classes : -------------------------------------------------------------------------- ---------------------------------------------- package org.akrogen.cxf; import org.akrogen.domain.User; import org.apache.cxf.jaxrs.provider.JSONProvider; public class MyJSONProvider extends JSONProvider { public MyJSONProvider() { Class[] userExtraClass = new Class[1]; userExtraClass[0] = User.class; super.setExtraClass(userExtraClass); } } -------------------------------------------------------------------------- ---------------------------------------------- And I use it like this : -------------------------------------------------------------------------- --------------- <osgi:service interface="org.akrogen.services.UserService"> <osgi:service-properties> <entry key="service.exported.interfaces" value="*" /> <entry key="service.exported.configs"value="org.apache.cxf.rs" />*<entry key="org.apache.cxf.rs.provider" value="org.akrogen.cxf.MyJSONProvider" /> * <entry key="service.exported.intents" value="HTTP" /> <entry key="org.apache.cxf.rs.address"value="http://localhost:9090/a";/> <entry key="org.apache.cxf.rs.databinding" value="jaxb" /> <!--<entry key="org.apache.cxf.rs.httpservice.context"value="/rest"/> --> </osgi:service-properties> <ref bean="userService" /> </osgi:service> -------------------------------------------------------------------------- --------------- And it works great. But I find it's not a clean solution. Here the 2 problems : 1) Cannot controlling JAXBCOntext with DOSGi With DOSgi, it seems we cannot configure JAXBContent liek explained in the doc : ------------------------------ <bean id="jaxbProvider" class="org.apache.cxf.jaxrs.provider.JSONProvider"> <property name="singleJaxbContext" value="true" /> <property name="extraClass"> <list> <value>org.akrogen.domain.User</value> </list> </property> </bean> ------------------------------ Because value is class name and nor Spring bean: ------------------------------ *<entry key="org.apache.cxf.rs.provider" value="org.akrogen.cxf.MyJSONProvider" /> * ------------------------------ I think it should be cool, if we can set a Spring bean is the property o*rg.apache.cxf.rs.provider *2) *AbstractJAXBProvider* should populate Generic Type? But I think to resolve the problem, it should be cool if ------------------------------ AbstractJAXBProvider#JAXBContext getJAXBContext(Class<?> type, Type genericType) throws JAXBException ------------------------------ populate the JAXBContext with the genericType too. Is it a reason that genericType is never used? Thank a lot for your help. Regards Angelo
