Not unless your code has a class of memory leaks that can cause ClassLoaders to be "pinned" in memory. If you do, you'll find that re-deploying your web application wastes a lot of memory, and ultimately you will get OOME after several reloads. > sometimes i did observe that there are certain cache issues which > make the application refers the old code even when new code has > been deployed,this usually get fixed with cleaning work & temp > directories, is this the expected behavior ?? No. If you have things like context-started threads still running after the web application should have been shut down, you can get problems like this. A Tomcat restart is the only thing that will clear those away. The work directory is likely not related unless your code uses the work directory for something. > does work & temp directories get recreated every time on > restart??,,can you help me in understand that under what scenarios > work & temp directories are created because at times at saw if i > delete work & temp directories then work is getting created not > temp directory on a restart. Work and temp directories are created whenever Tomcat needs them. The temp directory is guaranteed to be available by the servlet spec, so it's created if it does not exist. The rules for whether the work directory is required or not are unclear to me. > how work & temp is being used by a Tomcat ?? The temp dir is required by the servlet spec. I don't believe Tomcat uses it for anything. The work directory is used to cache resources from WAR files, to compile .jsp files into .java and ultimately .class files, etc. > how important is a temp directory for a code to run? Pretty important. Are you having some kind of problem with it? > I do see issues in the past in case temp directory is not present > in a catalina_base then the application throws error .while > startup.
