Hi.
I am new to this portal development, recently I started working on deploying a JSF application to Liferay Portal
using Apache jsf-portlet-bridge, able to deploy the application but I get this exception when trying to access the portlet.

13:41:56,777 ERROR [ETagFilter:136] java.lang.ClassCastException: org.apache.catalina.session.StandardSessionFacade cannot be cast to javax.portlet.PortletSession
java.lang.ClassCastException: org.apache.catalina.session.StandardSessionFacade cannot be cast to javax.portlet.PortletSession
at com.sun.faces.portlet.LifecycleImpl.restore(LifecycleImpl.java:387)
at com.sun.faces.portlet.LifecycleImpl.execute(LifecycleImpl.java:207)
at javax.faces.webapp.FacesServlet.service(FacesServlet.java:213)
Removed some of the exception trace.

This is the jar files list, I am using
commons-beanutils.jar
commons-codec-1.3.jar
commons-collections.jar
commons-digester.jar
commons-el.jar
commons-httpclient-3.1.jar
commons-lang.jar
commons-logging.jar
jaxb-api.jar
jaxb-impl.jar
jaxb-xjc.jar
jaxb1-impl.jar
jdom-b8.jar
jsf-api.jar
jsf-impl.jar
jsf-portlet.jar
jstl.jar
portals-bridges-common-1.0.jar
portals-bridges-jsf-1.0.jar

This how my JSP page looks
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>

<f:view>
<meta http-equiv="KEYWORDS" content="shipment, tracking, trace, rail, freight, union, pacific, railroad">

<h:form id="f">

<div align="center">
<table cellpadding="0" cellspacing="0" border="0" width="100%">
<tr>
<td class="txt"><span style="font-size: small"><ul>
<li><a href="TraceForm.jas?trace=trace"><h:outputText value="Trace"/></a></li>
<li><a href="/wet/secure/ListMaint.jas?6"><h:outputText value="Browse Lists"/></a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</li>
</ul></span>
</td>
</tr>
</table>


</div>
</h:form>

</f:view>
