Hi,
why the cxfrs producer not accept null query params? Should I set an
additional parameter to pass null value?
My route:
from("cxfrs:http://localhost:8080/tua";
+ "?resourceClasses="
+ "hu.fornax.tua.kodtar.protocol.rest.KodtarREST"
+ "&loggingFeatureEnabled=true"
+ "&providers=#jsonProvider")
.removeHeader("Content-Type")
.setHeader("CamelCxfRsUsingHttpAPI", constant("false"))
.log(ESBLog.ESB + "REST request: ${headers}")
.to("cxfrs:http://localhost:8080/tua-kodtar/rest";
+
"?resourceClasses=hu.fornax.tua.kodtar.protocol.rest.KodtarREST&throwExceptionOnFailure=false&loggingFeatureEnabled=true&providers=#jsonProvider")
.otherwise()
The rest interface:
@Path("/{type}")
public List<KodtarDto> getKodtarElemListByType(@PathParam("type")
KodtarType type, @QueryParam("id") Long id);
If I call the consumer (cxfrs://http://localhost:8080/tua) to proxy the request:
13:23:34,882 ERROR [org.apache.camel.processor.DefaultErrorHandler]

If the queryparam is set with value that is not null the route works
and calling the service consumer directly without adding "id" it works
as well (cxfrs:http://localhost:8080/tua-kodtar/rest)....
If I want to proxy the request getting NullPointerException.
env: WildFly-Camel 4.9.0
Thanks for your help!
