Personally I use the Tomcat Management Application - it lets you unload and reload a specific web application. According to the specs, reloadable="true" should work by monitoring the timestamps on the .class and .jar files - I dunno why it doesn't in some installations. Bill
There are some known problems in Tomcat 4 (specifically with 4.1.27 if I recall) with reloading. Tomcat 5 seems to have solved these issues (and I believe there is a patch for 4.1.27 but I can't vouch for it).
