I've been looking around the Apache/Jakarta site, and I can't find the
Realm-related stuff (I understand it's separate from Tomcat). We're
running Tomcat 4, and I'd like to hack the query JDBCRealm sends to
Oracle so username checks are not case insensitive. Btw, which JAR in
my Tomcat
Here's our server.xml's Realm element:
Realm className=org.apache.catalina.realm.JDBCRealm debug=99
driverName=oracle.jdbc.driver.OracleDriver
connectionURL=jdbc:oracle:thin:@192.168.1.144:1523:orcl
connectionName=scott connectionPassword=tiger userTable=users
userNameCol=username
Right now, we have one domain that goes to our web application, and we
want to another new domain to point to the same web app (it already
does). Naturally, if you access the site via the new domain, it tells
the browser that the certificate issued by the site doesn't match the
name of the site,
Wait a second...Tomcat will determine which cert to send down based upon
the IP address that the browser went to? I guess that makes sense...so
does the web server never get to see what domain the browser was looking
up to come to the site, or is that info available?

Hey there--just wondering if JDBCRealm with Tomcat 4 ever closes

Hello everyone, we're running Tomcat 4.1.27 and my conf/web.xml has a
