这是需要靠应用服务器来支持的。tomcat的管理界面已经有相应功能了。
当然支持class reload特性的应用服务器也是可以的（比如resin），但前提是更新jar足够快，需要在一个刷新时间内替换完旧的jar。

偶觉得严格意义上的持续服务是很难的。如果能做到不停止web application而完成升级也就能满足大部分应用需求了。

Posted by: snowbug Posted on: 2002-11-27 04:53 or you can 1. upload all the files to a temp directory first, for example, webapps/tempjute - takes a long time but the existing web app still works 2. then run a small script to rename the directories - takes no time 3. reload the application from tomcat admin - takes no time The interruption will be about 2 sec. if you are fast

good idea! the only shortcoming is uploading time is longer.
