You are setting the content type as application/json and I don't see where you're translating from JSON to a java object server side.
The payload from angular isn't going to come as a parameter, you're going to have to pull the payload, use something like jackson to go from JSON to java object, and then pass it down to your database calls. You also have issues with case sensitivity. On Friday, August 14, 2015 at 2:42:21 AM UTC-4, Ratanveer Singh wrote: > > My angularjs code is not properly call the servlet.
