Request/Response cycle.
There is no any "<% ... %>" in the audit jsp. Below is one simple
example of such file:
<%@ include file="/common/all.include.jsp" %>
<c:if test="${ audit != null }" >
<log:info msg="${ audit.event } : ${ audit.userName }" />
<security:login loginName="${ audit.userName }" event="$
{ audit.event }" sessionId="${ audit.sessionId }" />
</c:if>
"audit" is a hashtable object in session. it has all information
needed ( "event" - login|logout| .... , "userName", "sessionId" ).
<security:login> is a custom tag which does not have any <% ... %> in
it either just some <sql:...> tags.
This is actually what made me go this way. With ability to define new
tags using JSP (taglib) it is truly possible to have "java-less" JSP
application. Audit is the only spot which required some java coding,
with this JSPAudit valve I can code it once and then delegate all
actual audit business logic to JSP writer.
