title: How to call the post method of a servlet?
body: <p>Am I able to create an object of the servlet and call the post method and pass the required arguments or do I have to declare it inside the web.xml and if I do declare it inside the web.xml file, do I still have to create an object from the servlet, how does this work? 
  Im trying to use Google Cloud Storage, I already compiled the dependency in one of my modules, I also have the servlet class provided by google. thank you!</p>
