title: Pitfals of deploying/redploying app to Tomcat without restarting
body: <p>I have read that it is possible with Tomcat 5.5+ to deploy a war to a Tomcat server without a restart.  That sounds fantastic but I guess I am too skeptical about this functionality and it's reliability.  My previous experience (with Websphere) was that it was a best practice to restart the server to avoid memory problems, etc. So I wanted to get feedback as to what pitfalls might exist with Tomcat.  </p>
  
  <p>(To be clear about my experience, I developed java web apps for 5 years for a large company that partitioned the app developers from the app server engineers - we used Websphere - so I don't have a lot of experience with running/configuring any app servers myself)</p>
