void doPatch(javax.servlet.http.HttpServletRequest request,

      throws javax.servlet.ServletException,

    Perform a HTTP PATCH operation. The PATCH method requests that a set of changes described in the request entity be applied to the resource identified by the Request-URI. The set of changes is represented in a format called a "patch document" identified by a media type. The server MUST apply the entire set of changes atomically and never provide (e.g., in response to a GET during this operation) a partially modified representation. If the entire patch document cannot be successfully applied, then the server MUST NOT apply any of the changes.
    
    Parameters:
    
    request - an HttpServletRequest object that contains the request the client has made of the servlet
    
    response - an HttpServletResponse object that contains the response the servlet sends to the client
    
    Throws:
    
    java.io.IOException - if an input or output error is detected when the servlet handles the PATCH request
    
    javax.servlet.ServletException - if the request for the PATCH could not be handled
