I am writing a sample web application through session clustering with jetty using this article session-clustering-jetty
I have a apache httpd mod_proxy_balancer load balancer in front of two jetty instances running. My jetty-jdbc-sessions.xml file looks like this
<Set name="sessionIdManager">
<New id="idMgr" class="org.eclipse.jetty.server.session.JDBCSessionIdManager">
<Arg>
<Ref refid="Server"/>
</Arg>
<Set name="workerName"><Property name="jetty.jdbcSession.workerName" default="node1"/></Set>
<Set name="workerName"><Property name="jetty.jdbcSession.workerName" default="node2"/></Set>
<Set name="scavengeInterval"><Property name="jetty.jdbcSession.scavenge" default="1800"/></Set>
<!-- ===================================================================== -->
<!-- Uncomment either the datasource or driver setup and configure -->
<!-- ===================================================================== -->
<!--
<Set name="DatasourceName"><Property name="jetty.jdbcSession.datasource" default="javax.sql.DataSource/default"/></Set>
-->
<Call name="setDriverInfo">
<Arg><Property name="jetty.jdbcSession.driverClass"/></Arg>
<Arg><Property name="jetty.jdbcSession.connectionURL"/></Arg>
</Call>
</New>
</Set>
My deployable.xml file looks like below
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN"
"http://www.eclipse.org/jetty/configure_9_0.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
<Ref id="Server">
<Call id="idMgr" name="getSessionIdManager"/>
</Ref>
<Set name="sessionHandler">
<New class="org.eclipse.jetty.server.session.SessionHandler">
<Arg>
<New id="jdbcmgr" class="org.eclipse.jetty.server.session.JDBCSessionManager">
<Set name="sessionIdManager">
<Ref id="idMgr"/>
</Set>
</New>
</Arg>
</New>
</Set>
</Configure>
When I run my application and try to read session id from HttpServletRequest like below
String sessionId = request.getSession().getId();
I keep getting an exception
java.lang.ClassCastException: org.eclipse.jetty.server.session.HashedSession cannot be cast to org.eclipse.jetty.server.session.JDBCSessionManager$Session

Not sure what I am doing wrong here? JDBCSessionIdManager.addSession uses HttpSession and that's what I get in HttpServletRequest.
