text/html header not returned in response from Websphere when using ResponseEntity, works in Tomcat?

Question

Hi i have some code that works fine in Tomcat, but under Websphere the response being returned does not seem to take on the Content-Type header that I am specifically setting to 'text/html'

public ResponseEntity<?>  postAttachment(@ModelAttribute AttachmentDto attachmentDto) {
  HttpHeaders responseHeaders = new HttpHeaders();
  responseHeaders.setContentType(MediaType.TEXT_HTML);
  RestResponse<AttachmentDto> response = attachmentService.save(attachmentDto); 
  return new ResponseEntity<RestResponse<AttachmentDto>>(response, responseHeaders, HttpStatus.OK);

}

Any help appreciated.

Are you hitting WebSphere directly, or through an HTTP Server (such as IHS)? — Isaac

Please look at the Administrative Console more closely. You will find a view about mime types. WAS automatically sets mime types for everything that has defined suffixes and it ships with somewhat extensive list. These settings might overrule your application code.
