i would really appreciate some help. this is the situation. i have developed an android app that enables a user to purchase and download a file from a server. the purchase is verified by amazon server. so, i need a java server page (installed on my server) to do the following: the android app sends a token and a user id (both strings) to my server. my server then appends a secret code and forwards this to the amazon server. the amazon server then responds with a response code (200, 400, 404 or whatever). my server then either releases the file for download or notifies the android app that the verification failed.
unfortunately, i don't know anything about java server pages or servlets. i can get by with html and java (which i use in android programming) but i don't have the time to learn how to create a page (as described above). so i would really appreciate some help that could speed things up a bit , like some similar code examples that i could edit to my liking or maybe someone that's willing to do the job for a reasonable fee perhaps?
