Hi
When calling a service using PathParam with an object containing
java.util.Date, the custom ParamConverter is NOT getting invoked.
That is, getUserByDateRange2(GetUserByDateRangeRequest2 request) does NOT call
SomeDateConverter in code below.
Instead gives following error on Server.log;
--------------------------------------------------------------------
Payload: Parameter Class com.my.demo.rest.services.GetUserByDateRangeRequest2
has no constructor with single String parameter, static valueOf(String) or
fromString(String) methods
--------------------------------------------------------------------
This is a server side error message, not the client side one.
Do you have the converter registered on the server too ?
Cheers, Sergey
However, it is correctly getting invoked when using MatrixParam. That is,
getUserByDateRange(GetUserByDateRange request) calls SomeDateConverter as
expected.
Code tested using Apache CXF 3.0.2-SNAPSHOT (because it has fix for the needed
Date marshalling)
Am I missing something?
Appreciate greatly any help/pointers.
Thanks
Srini
