I start from begining - 
  - download struts-faces-20040407.tar.gz
  - add jsf libraries  in WEB-INF/lib and jsf tlds WEB-INF

all libraries are from struts-faces and JSF 1.0 final - I add only log4j-1.2.8.jar
(I have one applications from dbforms distribution - bookstore.war and after deploy this application
I have to have commons-loggings and log4j libs in all applications - I don't know why)

tomcat 5.0.19 start struts-faces fine
 - call localhost:8080/struts-faces and this work
 - register users work fine (I try empty filed and get errors fine)
 - I register user abcd (4 char) and it work fine)
 - log off
 - log on with abcd (password abcd) work fine
 - log off
 - log on and click button 'Log on' with empty username and password and this is error :
