Re: Messagebodywriter issue for RESTful web services

[Sergey Beryozkin]

Hi, thanks for the confirmation....
You can also explicitly register a JAXB provider and instruct it to 
'marshalAsJaxbElement' and then you can avoid setting this annotation

cheers, Sergey

  I found the issue. I forgot to add "@XmlRootElement(name = 
"UserContactResponse")" above the class

  @XmlRootElement(name = "UserContactResponse")

  public class UserContactResponse {

  I am getting the following error and I tried all options. I remember that 
similar code was working few months back without any custom Serializers

  1) Error in log

  2) Interface class
  package com.xxx.ws.rest;

  import java.util.List;

  import javax.ws.rs.Consumes;
  import javax.ws.rs.GET;
  import javax.ws.rs.Path;
  import javax.ws.rs.PathParam;
  import javax.ws.rs.Produces;
  import javax.ws.rs.core.PathSegment;

  import com.xxx.ws.soap.PatientMatchResp;
  import com.xxx.ws.soap.UserContactResponse;

  @Path("/patientmatch/")

  @Consumes( {  "application/xml" })
  @Produces( {  "application/xml" })
  public interface XXXService {


   
     @GET
       @Path("/{userid}/contacts/{contactId}")
       public UserContactResponse getContact(@PathParam("userid")
       String userGuid, @PathParam("contactId")
       String contactId);
  }

  3) Impl class


  @WebService(endpointInterface = "com.xxx.ws.rest.XXXService", serviceName = 
"/")
  public class XXXServiceImpl implements XXXService {

   private static Logger log = Logger.getLogger(XXXServiceImpl .class);

  public UserContactResponse getContact(String userid, String contactId) {
    // TODO Auto-generated method stub
    UserContactResponse ucr = new UserContactResponse();
    UserContact uc = new UserContact();
    uc.setCity("fremont");
    uc.setActive(true);
    uc.setAptNumber("11");
    uc.setChkPmtToCo(true);
    uc.setCompany("fff");
    ucr.setUserContact(uc);
    return ucr;
   }
    
  }

  4) UserContactResponse (this contains UserContact which has few String and 
Long fieds. Thats all. No arrays or List)

  import javax.xml.bind.annotation.XmlAccessType;
  import javax.xml.bind.annotation.XmlAccessorType;
  import javax.xml.bind.annotation.XmlElement;
  import javax.xml.bind.annotation.XmlType;

  @XmlAccessorType(XmlAccessType.FIELD)
  @XmlType(name = "UserContactResponse", propOrder = { "userContact"
  })
  public class UserContactResponse {

   @XmlElement(name = "UserContact", required = true)
   UserContact userContact;

   public UserContact getUserContact() {
    return userContact;
   }

   public void setUserContact(UserContact userContact) {
    this.userContact = userContact;
   }


   }



  4) cxf-bean.xml file
  <jaxws:endpoint 

  id="XXXService" 

  implementor="com.xxx.ws.soap.XXXServiceImpl" 

  address="/XXXService"/>


  <bean id="xxxRestService" class="com.xxx.ws.rest.XXXServiceImpl" />
