learnbrl throws StringIndexOutOfBoundsException

[Jake M. <jac...@gm...>]

Hello.  I'm trying to get learnbrl running under Tomcat 4 on os x
10.4.  Using Tomcat 4 because that's what my servlet host will be
using (FuturePoint.com - they look good).  I've set up learnbrl.local
as a virtual host in /etc/hosts and in tomcat's server.xml, and when I
go to http://learnbrl.local:8080/index.brl I get a brl error page that
says Error: String index out of range: -1.  The exception stack trace
is below.  Does anyone recognize this situation?  I just unpacked
learnbrl.war, haven't touched it.  JAVA_HOME is pointing to jdk 1.5.
My CLASSPATH variable is blank at the moment.  I know I've run
learnbrl before, but I don't remember what was different.  I was using
a different version of tomcat - would that make a difference?

Thanks for any help.

- Jake
