How to handle page maintenance with spring MVC

Does anyone have expirience with maintenance page using spring MVC? What I am currently doing is I have one shell script which copies index.html and css to web app root folder, and when they are done with copying the maintanence site is displayed.

In meantime I do changes I delete classes and upload the开发者_开发技巧 new ones and then delete html and css files and everything is back to normal. This works on tomcat server, but when I tried this on jboss server, I get 404 page which is trying to point to index.jsp which naturally doesn't exist.

Is there a way to handle this more elegantly? I'm sure there must be, can someone share their expirience with this? thank you

Put an Apache HTTPD server in front which uses the Tomcat Connector (als known as mod_jk) to delegate the requests to Tomcat/JBoss. Configure Apache HTTPD to display the desired maintenance page as 404/503 error page.

have a look at this - fully programmatic - solution:
