title: Call REST GET Service from JSP
body: <p>I have a JSP that dynamically sets the page header of my application.</p>
  
  <p>However, I want to be able to call the REST Service that gets user details based on the system user. I already have the system user value but need to call the backend service to get the details from the database. This is already implemented but I don't know how to setup the JSP to do this. </p>
  
  <p>I do not want to use javascript as this is being used for the extjs side of things. </p>
