Good day,
While trying to get a Tomcat instance started up, I keep getting the
stacktrace listed below. Note that this error only occurs when attempting
to start the server in $CATALINA_BASE. If I set CATALINA_BASE =
CATALINA_HOME, the server starts up fine.
Further, the tomcat-users (see below) is identical (copies, not links)
between CATALINA_HOME/conf/tomcat-users.xml &
CATALINA_BASE/conf/tomcat-users.
I can see nothing wrong in either of my server.xml's or my tomcat-user file.
Any help would be appreciated in this matter.. Its quite frustratring.
Thank you!
Regards,
Lorin
