Hi Giorgio,
Do keep in mind that logback-access is for access logging, i.e. logs
generated by the container to inform the administator about requests
made to the container.

A rypical access log entry looks like the following (on one line):

127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET /apache_pb.gif \
  HTTP/1.0" 200 2326

Logback-access is installed at the container level, in your case
Tomcat. In contrast, logback-classic is installed at the level of the
web-application to handle logs generated by your software via calls
made to the slf4j api.

Does this help?
