[Trinidad] problem when deploy trinidad-demo-1.2.14.war or trinidad-blank-1.2.14.war on Tomcat 6

[Fahmi Hachicha]

Hello,

When deploying the examples of the Trinidad 1.2.14 on a Tomcat 6 Web Server,
the WebApp does not start due to an error :

org.apache.catalina.core.StandardContext start
GRAVE: Error filterStart
22 févr. 2011 20:29:40 org.apache.catalina.core.StandardContext start
GRAVE: Erreur de démarrage du contexte [/trinidad-demo-1.2.14] suite aux
erreurs précédentes

How must I configure Tomcat 6 Server to be able to run these demo examples ?

Thanks
Fahmi
