Subject Re: Authenticator valve at the host level, not possible?
Date Mon, 10 Nov 2003 15:46:46 GMT
Your valve is supposed to be initialized with a loginConfig object, itself
initialized from the security constraints defined in a web.xml file.
How can tomcat configure your valvle if it is not attached to a context (i.e. no
web.xml)?
