In the end I wipped up something like this, which seem to be serving the
purpose.
Now I need to figure out how to do something similar on the Soap side.
public class RestExceptionMapper implements ExceptionMapper<Exception>
{
private static Log logger = LogFactory.getLog(RestExceptionMapper.class);
private static final ResourceBundle BUNDLE =
BundleUtils.getBundle(WebApplicationExceptionMapper.class);
public Response toResponse(Exception exception)
{
logger.error("REST exception: ", exception);
if (exception instanceof WSAuthException)
{
// do not give details on auth failure
return Response.status(Response.Status.FORBIDDEN).build();
}
else if (exception instanceof WSBaseException)
{
// let custom port exception out
return
Response.status(Response.Status.INTERNAL_SERVER_ERROR).type(MediaType.TEXT_PLAIN).entity(
exception.getLocalizedMessage()).build();
}
else if (exception instanceof WebApplicationException)
{
return toResponse2((WebApplicationException) exception);
}
//TODO: add one more for platform level exceptions
// the rest are server errors..
return Response.status(Response.Status.INTERNAL_SERVER_ERROR).build();
}
public Response toResponse2(WebApplicationException ex)
{
if (logger.isWarnEnabled())
{
String message = ex.getCause() == null ? ex.getMessage() :
ex.getCause().getMessage();
if (message == null)
{
if (ex.getCause() != null)
{
message = "cause is " + ex.getCause().getClass().getName();
}
else
{
message = "no cause is available";
}
}
org.apache.cxf.common.i18n.Message errorMsg =
new org.apache.cxf.common.i18n.Message("WEB_APP_EXCEPTION",
BUNDLE, message);
logger.warn(errorMsg.toString());
}
Response r = ex.getResponse();
if (r == null)
{
String message = null;
if (ex.getCause() == null)
{
message = new
org.apache.cxf.common.i18n.Message("DEFAULT_EXCEPTION_MESSAGE",
BUNDLE).toString();
}
else
{
message = ex.getCause().getMessage();
if (message == null)
{
message = ex.getCause().getClass().getName();
}
}
r =
Response.status(Response.Status.INTERNAL_SERVER_ERROR).type(MediaType.TEXT_PLAIN).entity(message).build();
}
return r;
}
}
