Since our system uses JBOSS3.2.3.To disable session persistence, we can create
an entry of Manager element that sets the pathname to an empty value in
\jboss-3.2.3\server\default\deploy\jbossweb-tomcat41.sar\META-INF\jboss-service.xml.
but if we put the above mentioned entry then it throws NullPointerException for
EmbeddedTomcatService.
snippet of log file is given below
