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()     #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>")   methodend classend
