Prologue: Rest Service Tutorial

Starting new tutorial series, on Rest services. Rest-Services will act as rest-end points for fecthing and querying the data from database, and will give you an ease to assemble the endpoint services for all the major operation, to perform on your database. I’ll try to make these services, scalable, and secure enough to run them from anywhere, and you will get ease to operate and modify them as per your ease.

Initial Set of technology:

  • Java 1.5
  • JAX-RS
  • Restful Services
  • Mongo DB
  • Spring Framework
  • Tomcat
  • Misc .. as we go ahead
