Change Version of Tomcat?

[kkttt]

My reply in thread
http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t=forums/ seem to be appearing...

Anyway, the Tomcat crossContext bug seems to have reappeared in 4.1.12
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=10544

Is there a way to change the version of Tomcat after installing the JBoss+Tomcat package? Can we replace the tomcat with another version?

Or is it possible to install JBoss alone and install our own version of Tomcat?

Thanks.
