[gatein-dev] PortalClusteredSSOSupportValve issue in Tomcat

[Marek Posolda]

Hi Julien,

is there something special which could be done to reproduce the issue? I 
tried to verify with latest GateIn master and Tomcat 7.0.32 but not 
seeing any problems. Do I need to use some web application with servlet 
3.0 descriptor? Do you have some app to share which could be use to 
reproduce this?

Actually picketlink-jbas7 is not part of Tomcat packaging. I am not 
seeing it in GATEIN_TOMCAT_HOME/lib/ . But SSODelegateValve is part of 
sso-integration-1.3.1.Final.jar which is part of Tomcat packaging...

Thing is that signature of PortalClusteredSSOSupportValve is:
{code}
public class PortalClusteredSSOSupportValve extends ValveBase implements 
Lifecycle {
{code}

but signature of SSODelegateValve is:
{code}
public class SSODelegateValve implements Valve, Contained, 
MBeanRegistration, Lifecycle
{code}

So it seems that your issue with "class 
org.exoplatform.web.login.PortalClusteredSSOSupportValve overrides final 
method start.()" really won't happen for SSODelegateValve. Hard to say 
without being able
to reproduce...

So it seems that moving single PortalClusteredSSOSupportValve to packaging/jboss-as7 won't be sufficient...
