title: ServletFileUpload.parseRequest() wants RequestContext instead of HttpServletRequest request
body: <p>i am writing a web app and i want to upload a file to the servlet.
  i read that i can use ServletFileUpload.parseRequest(request)
  it works on one computer.
  but when i try to run the code on another computer i get an error that the function needs  RequestContext: ServletFileUpload.parseRequest(RequestContext)</p>
  
  <p>on the computer that the function works with HttpServletRequest i see the function with RequestContext. but i don't use it</p>
  
  <p>is there another way to upload files to servlet?</p>
