Summary: Session is lost when application is reloaded through
touching the war file
Product: Tomcat 6
Version: 6.0.18
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: adrian...@gmail.com

Example project
I tried a very basic example, based on Maven quickstart. web.xml is almost
empty, and a jsp page:
=================
<html>
<body>
<%
String x = (String) request.getSession(true).getAttribute("x");
if (x == null)
x = "0";
int y = Integer.valueOf(x) + 1;
request.getSession(true).setAttribute("x", String.valueOf(y));
%>
<%= y %>
</body>
</html>
=================
So I start reloading the page. The number increments. I can stop/start or
reload the app. The number continue incrementing.
Then I touch (with gnuwin32 touch utility) the war file. The Tomcat console
displays:
=================
26/03/2009 11:11:28 org.apache.catalina.core.StandardContext reload
INFO: Reloading this Context has started
26/03/2009 11:12:02 org.apache.catalina.startup.HostConfig checkResources
INFO: Undeploying context [/example]
26/03/2009 11:12:02 org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive example.war
=================
You see, it undeployed, and the counter has reseted.
Now, I tried delete webapps/example. After some seconds, the war is exploded
and same thing as above happens.
Then I tried to delete webapps/example/*, leaving the directory empty. This
way, I can manually extract the war there, and session is preserved.
Charles (Chuck) Caldarale, said this is an inconsistency worth registering.
