Disabling Session Persistence

Since JBoss-3.2.6RC1:

The default tomcat session manager will persist sessions. This can lead to problems when restarting jboss or redeploying a war if the session contains non-serializable data.

To disable session persistence, you create a WEB-INF/context.xml with a Manager element that sets the pathname to an empty value:

<Context>
   <Manager className="org.apache.catalina.session.StandardManager"
      pathname="" ></Manager>
</Context>

JBoss-3.2.5 and earlier do not read the WEB-INF/context.xml file.

JBoss 4.0.3 has this disabled by default.  See /jboss-4.0.3/server/default/deploy/jbossweb-tomcat55.sar/context.xml
