Well ..sort of The recommended way of creating a web application is to create a webapp .war and deploy it to %TOMCAT_HOME%\webapps once you accomplish this objective Tomcat will note the new war and create folder %TOMCAT_HOME\webapps\NameOfWebApplicationWar wait a minute ..how does Tomcat handle 'temp' and or 'work' files ??? Tomcat has a 'work' folder located at %TOMCAT_HOME%\work\Catalina\ServerWhereDeployed\WebAppName this is where the REAL work is being done by tomcat..you will notice that after copying a new class or a new jar or a new war your new class is not taking hold? that is because the work folder %TOMCAT_HOME%\work\Catalina\ServerWhereDeployed\WebAppName has not been updated doing a specific undeploy and then deploy will fix this (as well as re-reading your web.xml) of course there is shutting down Tomcat and starting Tomcat should re-reploy the webapps
