You need to set the Response encapsulated in the WebApplicationException, e.g. by using this constructor:
https://jsr311.dev.java.net/nonav/releases/1.0/javax/ws/rs/WebApplicationException.html#WebApplicationException(java.lang.Throwable,%20javax.ws.rs.core.Response)
The Response should contain the desired status code and a body that contains any additional information you want to send to the client.
An alternative to using WebApplicationException as below is to provide an ExceptionMapper<CustomException>:
https://jsr311.dev.java.net/nonav/releases/1.0/javax/ws/rs/ext/ExceptionMapper.html
The ExceptionMapper will be called to convert a CustomException into a Response so your resource methods can just throw CustomException directly.
