Example

This example demonstrates how this works in a BBJSP web-page

<%
    REM == INITIALIZE SOME DATA
    #Request!.setAttribute("foo","This is FOO")
    #Request!.setAttribute("woo","This is WOO")
%>
<%@ taglib uri='/WEB-CFG/tld/core.tld' prefix='c' %>
<html>
    <body>
        <ul>
            <c:iterate data="<%= #getRequest().getAttributeNames() %>" id="name">
                <%
                    REM = Get the "name" from the page context
                    name$ = #PageContext!.getAttribute("name")
                %>
                <li><b>${name}</b> = <%= str(#getRequest().getAttribute(name$)) %>
            </c:iterate>
        </ul>
    </body>
</html>

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!.getAttributeNames()
    sz = vectNames!.size()
    if sz then
      s!.write("<ul>")
      for i = 0 to sz - 1
        name$ = vectNames!.get(i)
        s!.write("<li>" + name$ + #request!.getAttribute(name$))
      next i
      s!.write("</ul>")
    endif
    s!.write("</body></html>")
