Hi,
I had to use a custom httpBinding, since the DefaultHttpBinding
doWriteExceptionResponse always writes error code 500. I had to change
this because I wanted to have distinct error code depending on what
exactly went wrong. If the XSD validating fails, I return a 400 Bad
Request, when the queue is full I return a 504 Gateway timeout. The
client can than handle the response in different ways if he wants.
Is it intentionally that 500 is always returned by default or is there
a different way to specify the error code? I tried using the
Exchange.HTTP_RESPONSE_CODE header but this does only work for
non-exception cases.
@Override
public void doWriteExceptionResponse(Throwable exception,
HttpServletResponse response) throws IOException {
int errorCode = 500;
if (exception instanceof ValidationException) {
errorCode = HttpServletResponse.SC_BAD_REQUEST;
} else if (exception instanceof
org.apache.camel.ExchangeTimedOutException) {
errorCode = HttpServletResponse.SC_GATEWAY_TIMEOUT;
} else if (exception instanceof RollbackExchangeException) {
errorCode = HttpServletResponse.SC_SERVICE_UNAVAILABLE;
} else {
errorCode =
HttpServletResponse.SC_INTERNAL_SERVER_ERROR;
}
response.setStatus(errorCode); // 500 for internal server error
response.setContentType("text/plain");
// append the stacktrace as response
PrintWriter pw = response.getWriter();
exception.printStackTrace(pw);
pw.flush();
}
Regards,
Leen
