Hi everyone,
i have a problem in studying El...
when i create a Map in <% %> area:
<%
SortedMap map = new SortedMap;
map.put("key", "value");
%>
and want to display the data by using EL
${map.key}
but it show me nothing....
what is the reason?
it can show me ${header["user-agent"]}
that mean the page can run El at my
tomcat..
also, do EL only for display the date?
(for replace the <%= XX %> tag)
how do i create instance by using EL?
i always get confuse with the format ${aaa.bbb.ccc}
thanks
