Benjamin,

The webapp web.xml was modified to use the filters you pointed out
below, using /* as the filter mapping.

We are getting the following stacktrace in the filter:

org.apache.catalina.core.StandardWrapperValve invoke
GRAVE: "Servlet.service()" pour la servlet jsp a généré une exception
javax.servlet.ServletException: Could not initialize
PortalContainer.Current ExoContainer is:

Are there any other configuration items that need to be addressed in
the web.xml or is there some java code that needs to be written to
correctly initialize the webapp in the exo environment ?

Please let us know if any other code or configuration items are useful
to you so Michael can send them to you.

Thanks again,

Luis
