Client Jersey and RESTful put with list of object - rest

Question

In my application I'm using the library jersey and Apache CXF for the implementation of the REST calls . In particular, I have created my DTO, a service and a dao to insert a record into a database through the put method.
The code below is working, but my problem is when certain to pass a list of DTO that the client reports an error:
/* Client Rest */
WebResource service = clientJersey.get().resource(this.baseURI);
GaraDTO garaDTO = new GaraDTO();
garaDTO.setVersion("0");
..........................
ClientResponse response = service.path("rest").path("gare").accept(this.mediaType).put(ClientResponse.class, garaDTO);
/* DTO */
#XmlRootElement(name = "gara")
public class GaraDTO {
private Integer version;
. . . . . . . . . . . .
public GaraDTO(){
}
#XmlElement
public Integer getVersion() {
return version;
}
public void setVersion(Integer version) {
this.version = version;
}
. . . . . . . . . . . .
}
/* Service */
#Override
#PUT
#Consumes(MediaType.APPLICATION_XML)
public void putInsert(GaraDTO garaDto){
....................
//insert DB
....................
}
If, after having created an ArrayList of DTO, step this list to the client I get an error.
List<GaraDTO> listGaraDTO = new ArrayList();
listGaraDTO.add(garaDTO1);
listGaraDTO.add(garaDTO2);
..............................
ClientResponse response = service.path("rest").path("gare").accept(this.mediaType).put(ClientResponse.class, listGaraDTO);
How can I pass a list of DTO?
thanks

Answer 1

If you want your API to accept a List, you need to make it actually accept a List, and not a single GaraDTO.
