title: Is there a way to deploy a jar without restarting in Tomcat 9?
body: <p>I know this question has came up before here, however this is in regards to tomcat 9.</p>
  
  <p>Is there anything that has changed in latest tomcat releases that allows to deploy a jar file without restarting tomcat ? We have been using tomcat 7 in our development and all developers restarting tomcat has been time consuming. Its application that has 700 java files that gets built in to a .jar file and about 1000 jsp files that rely on those .jar file, we are not using war. Can WatchedResource be used for this ?</p>
