Class WebApplicationExceptionMapper

java.lang.Object
org.gcube.informationsystem.resourceregistry.rest.providers.WebApplicationExceptionMapper
All Implemented Interfaces:
jakarta.ws.rs.ext.ExceptionMapper<jakarta.ws.rs.WebApplicationException>
@Provider public class WebApplicationExceptionMapper extends Object implements jakarta.ws.rs.ext.ExceptionMapper<jakarta.ws.rs.WebApplicationException>
Global JAX-RS ExceptionMapper giving the JSON error body of the service to the WebApplicationExceptions: the 401 and 403 of the Policy Enforcement Points, and the errors of the JAX-RS runtime itself (e.g. 404 for an unknown path, 405). Without it, the container answers them with its own HTML error page.

The status and the headers of the exception's response are kept (e.g. the WWW-Authenticate challenge of a 401); the body is built by ErrorResponseBody from the exception's message. A response that already carries an entity, or whose status is not an error, is returned unchanged.
