Subject Re: Digested Passwords and the server/lib/catalina.jar file
Date Tue, 10 Sep 2002 17:50:29 GMT
Ok I've not followed the entire thread, but many moons ago (using Tomcat
4.0.3) I did just this and I simply imported
org.apache.catalina.realm.JDBCRealm into my struts action and called
executed the following to get a hashed value for the user's new password.


Where ud is a class that needs its password set in hashed format, and tf is
the web form that has the new password.

On my server catalina.jar is in $TOMCAT/server/lib which I think is the
usual home for it.  Not sure if this is what you wanted but there it is if
you need it.
