Subject Re: Moving to Tomcat 4.1.18
Date Thu, 13 Feb 2003 07:13:51 GMT
Ben's timeline is a good one.  The problems that will bite you first is if
you have any custom Interceptors (e.g. Realms) in your 3.2.x app.  These
won't port without a total re-write.  If your not accessing Tomcat
internals, then the port should be painless (famous last words :).
