Re: [Resteasy-developers] Could not find MessageBodyWriter for response object of type: java.util.ArrayList of media type: application/xml

[Xavier C. <xc...@gm...>]

Hello Heiko,

Can you try with a GenericEntity wrapper to your list of domain entities ?

Response foo() {
  GenericEntity<List<MyType>>  x = new GenericEntity<List<MyType>>();
  ...
  return Response.ok(x).build();
}

HTH
Best regards,
/Xavier
