Usage

From source file:com.bios.controller.services.UpdateBidService.java

/**
* Handles the HTTP <code>GET</code> method which updates a bid. Firstly, the token
* is checked for its validity. If the token is valid, the method then goes into the
* respective DAOs to look for the bid. If the bid is valid and can be deleted, the
* bid is then deleted from the DAO and the database. Subsequentyly, a json object
* with the status "success" will be created. If any errors occur such as an
* invalid course or missing token is detected, a json object with the status "error"
* will be created with a json array of the erros that caused the failure to update.
* @param request servlet request//w ww  .j a  va  2  s  .  c om
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
