title: Tomcat: hot deploying new jars
body: <p>Can you hot deploy JAR files on Tomcat 5? The idea is to avoid restarting Tomcat and still be able to load (via reflection) some class from a newly added JAR.
  Can it be done? How? Is it unadvisable for a production system? 
  Thanks</p>
  
  <p><strong>Edit</strong>: my scenario requires the addition of new JAR files for which the names aren't known in advance. Can the server be "watching" a directory of JARs rather than specific JARs?</p>
