I am adding a redis implementation (jedis) to my application. I have a
jedis implementation class that holds the connection pool and interfaces

referenced from that point on by all of the webapps in the host. Is
there an 'architected/correct' way to set this up?
I'd suggest configuring it as a global JNDI resource [1] and then using
resource links to make it available to the web applications that need
it. If every web application needs it, you can add the resource link to
$CATALINA_BASE/conf/context.xml and then will add the link to every web
application deployed on the Tomcat instance.
