Hi Sergey,
I'm testing also other endPoints after their RESTization and I've found
another problem connected to particular input parameters...
I've this ws method:
@GET
@Path("/parseGenCommandArgs")
@ApiOperation(value = "Parses the given set of arguments according to
the
data model of the given command in order to prepare the XML to be sent to
Dory for the realization of the given generic command.",
notes = "Returns a String representing the
XML to be sent to Dory.",
response = String.class, produces
="application/xml,application/json")
public String parseGenCommandArgs(
@ApiParam(value = "appGardenID", required = true)
@WebParam(name =
"appGardenID") @QueryParam("appGardenID")
@CxfWSAuthGrain(type=authType.appGarden) int appGardenID,
@ApiParam(value = "protType", required = true)
@WebParam(name =
"protType") @QueryParam("protType") short protType,
@ApiParam(value = "profileID", required = true)
@WebParam(name =
"profileID") @QueryParam("profileID") int profileID,
@ApiParam(value = "objectIDhigh", required = true)
@WebParam(name =
"objectIDhigh") @QueryParam("objectIDhigh") int objectIDhigh,
@ApiParam(value = "objectIDlow", required = true)
@WebParam(name =
"objectIDlow") @QueryParam("objectIDlow") int objectIDlow,
@ApiParam(value = "args", required = true) @WebParam(name =
"args")
@QueryParam("args") List<String[]> args) throws Exception;
and when I call the method the exception:
java.lang.ClassCastException:
sun.reflect.generics.reflectiveObjects.GenericArrayTypeImpl cannot be cast
to java.lang.Class
occurs on server side, before arriving in the ws method implementor.
It is due to the serialization of the List<String[]> input parameter.
I've tried to remove the annotation @QueryParam("args") but in this case it
continue to not work and a class cast exception occurs client side.
Any idea about this problem?
First of all, thanks for testing the way the JAX-RS runtime maps the
request info to various parameters. In this specific case, same as with
the byte[] case, I'd rather see a different type of exception, as
opposed to ClassCastException, which is a bug.
On the other hand, I don't think a query parameter can be meaningfully
represented as List<String[]>, I don't know what it means :-). As I said
the runtime should probably throw a better exception, I need to think
about it...
IMHO, having SOAP interfaces reused to accept non-SOAP requests works
reasonably well for simple enough interfaces. When we have complex
signatures then it'd be better to create a simple RS wrapper which would
accept the request via some straightforward parameters, then prepare
parameters in a form expected by a SOAP service implementation, and then
delegate...
That said, I'll try to get to updating the runtime to behave a bit
better in cases like this one
Cheers, Sergey
Thanks,
Andrea
P.S.
For the previous problem it is solved using the Byte[] or removing the
@QueryParam annotation.
