Unable to eradicate 'Error ListenerStart'

[Vasanth Jayabalan, modificado hace 12 años.]

Hi,

I created a very simple portlet in grails using portlet plugins available for the framework. When I deployed the war to a Liferay instance running Tomcat 6.x, I got the following error during startup:

16:16:47,383 INFO [PortletAutoDeployListener:81] Portlets for /srv/liferay/liferay-portal-6.0.6/deploy/demo-portlets.war copied successfully. Deployment will start in a few seconds.
Oct 24, 2011 4:16:49 PM org.apache.catalina.startup.HostConfig deployDirectory
INFO: Deploying web application directory demo-portlets
Oct 24, 2011 4:16:50 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Oct 24, 2011 4:16:50 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/demo-portlets] startup failed due to previous errors

A lot of posts in some forums mentioned that the app may have a conflicting servlet.jar file that tomcat has in it's lib directory and that any j2ee specific jars should be removed from the app. I totally agree to this statement. However, I don't have any j2ee specific jars in my app. Then why would I get this error?

thanks,
Vasanth
