This example demonstrates how this works in a BBJSP servlet

class public MyServlet

  field private BBjspWebRequest request!
  field private BBjspWebResponse response!
  field private BBjspWebSession session!

  method public void service(BBjspServletContext context!)

    #request! = context!.getRequest()
    #response! = context!.getResponse()

    #session! = #request!.getSession()
    s! = #response!.getOutputStream()

    #response!.setContentType("text/html")

    s!.write("<html><body><h1>Hello from BBJSP</h1>")
    names! = #session!.getAttributeNames()
    if (names!.size()>0) then
      s!.write("<ul>")
      for i = 1 to names!.size()
        name$ = names!.get(i-1)
        s!.write("<li>"+name$ + ":" + session!.getAttribute(name$))
      next i
      s!.write("</ul>")
    else
      s!.write("<br/>No session variables!<br/>")
    endif
    s!.write("</body></html>")
