<%@ page import="com.opensymphony.xwork2.*"%> <%@ page import="com.opensymphony.xwork2.util.*"%> <%@ page import="java.util.*"%> <% ActionContext cxt = ActionContext.getContext(); out.println("<h2>ValueStack</h2>"); ValueStack stack = cxt.getValueStack(); List list = (List) stack.getRoot(); for (int i=0; i<list.size(); i++) { out.print("<FONT Color='Red'>" + list.get(i)+"</FONT>"); out.println("<BR/>"); } out.println("<h2>ContextMap</h2>"); Map map = cxt.getContextMap(); Set set = map.entrySet(); for (Iterator it = set.iterator(); it.hasNext();) { Map.Entry es = (Map.Entry) it.next(); // key out.print("<B><Font Color='Red'>"+es.getKey()+"</FONT></B>"); // value out.print("=" + es.getValue()); out.println("<br/>"); } %>
