Birodh, you probably need one since you are flying Jet.  As far as I know, if you are connecting between Cathay and Dragon, you are exempt provided that the transit time does not exceed 12 hours (also see the previous posts).  Also, I think, recently RA passengers were also granted exemption (I assume this applies to passengers traveling selected routes and connecting from selected airlines).  You may want to apply for your visa ASAP or change your route since you are traveling next week.  Good luck!!!
