Hi James,
I've been using this precise setup for years, first on a dedicated
hosted server and recently on EC2/Linux2. I use mod_jk.
The first step is to make sure httpd recognizes all of the domain names
and subdomains. That includes the vhost definitions of all of the
domains and

Did you look in the changelog?
Hint
I've encountered some very strange behavior in a new TC instance. It's
not actually 'new'. I cloned an Amazon EC2 that had a fully functional
ApacheHTTPD/Tomcat. I replaced the domain on the clone with a new
domain. Otherwise, nothing was changed. I use JSTL extensively on both

I need some advice. I need to maintain a set of long-running threads.
When a request comes in, I need to determine if I have a thread started

So moving the database or moving the client (app server) with

If the client always adjusts both ways, there shouldn't be any
