how to log in Tomcat administration page
downloaded apache-tomcat-6.0.10
OS:window xp
Tomcat's servlets/JSPs execute fine, but Tomcat denies access to the Tomcat Manager, Tomcat Administration to log in for web application with database connection.
The respective webapps and manager.xml and admin.xml are available and seem to look fine.
Tomcat even seems to log in my default user
tomcat and password tomcat or admin | admin .
error message;invalid user and password.
how can I log in?
