  field private BBjspWebResponse response!
  field private BBjspWebSession session!
  
  method public void service(BBjspServletContext context!)
       
    #request! = context!.getRequest()
    #response! = context!.getResponse()

    #response!.setContentType("text/html")
    s! = #response!.getOutputStream()
    
    #session! = #request!.getSession()
    
    s!.write("<html><body><h1>Hello from BBJSP</h1>")
    vectNames! = #request!.getHeaderNames()
    sz = vectNames!.size()
    if sz then
      s!.write("<ul>")
      for i = 0 to sz - 1
        name$ = vectNames!.get(i)
        s!.write("<li>" + name$ + #request!.getHeader(name$))
      next i
      s!.write("</ul>")
    endif
    s!.write("</body></html>")
