Hi all, I have this code in server side :

Code:
	
@RequestMapping(method=RequestMethod.DELETE,value="/{id}/blabla/{name:.*}")
     public @ResponseBody PersonnalObjectResponse delete(@PathVariable(value="id") String id,@PathVariable(value="name") String name, HttpServletRequest request, HttpServletResponse response) throws Exception {
		//SOME DELETE CODE who throw exception
		return new PersonnalObjectResponse();

	}


@ExceptionHandler(Exception.class)
	public @ResponseBody PersonnalObjectResponse handleException(Exception ex, HttpServletRequest request, HttpServletResponse response) {
		response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
		return new PersonnalObjectResponse();
	}
when i call /someID/blabla/file => My DELETE CODE throw EXCEPTION => My Exception Handler Catch this and return a PersonnalObjectResponse => response is correctly send in JSON.

when i call /someID/blabla/file.txt => My DELETE CODE throw EXCEPTION => My Exception Handler Catch this and return a PersonnalObjectResponse => HttpMediaTypeNotAcceptableException ?!?.
