Is there any way to configure Tomcat to use updated class files with restarting the server? The main point is that if I create a new version of the class file and then FTP this version to the correct directory on the server, the server apparently continues to use the older version of the class file. One way to solve this is by refreshing the server. However, we do not want to refresh the server as this may cause complications for clients who are already connected. Is there any way to accomplish this without refreshing the server?
