Hi Jim, all I can say is, that I was not able to unmarshal the anonymous
array containing a anonymous object returned from a POST to traverse/path.
All I got was a ArrayOutOfBounds exception (I used the
maven jersey-json dependency). Maybe just an issue with the combination of
Jersey and JAXB.
Normally this code should work:
GenericType<Collection<Traverse>> genericType = new
GenericType<Collection<Traverse>>() {};
Collection<Traverse> ja = webResource.path("node/3/traverse/path")
.accept(MediaType.APPLICATION_JSON)
.type(MediaType.APPLICATION_JSON)
.post(genericType, "{\"order\":\"depth first\", \"max
depth\": 1}");
for this JAXB Entity:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement
public class Traverse {
public String start;
. . .
}
And I did not get any answer from the Jersey users list.
Java.net is currently down once again :-( so I can not post the link to my
question.
