维护期间更改Java EE应用程序上的欢迎页面

Question

I need to show a message to users like : "The application will be down for two hours". Until now I rename my index.htm , my login.jsp and I uploaded another index.html with that message. Also I upload another html page pointing to my renamed login.jsp to let me in. Is there any other way to do that, more simple?

My application server is SunONE 6.1

Answer 1

Web Application contains a file named web.xml also called Deployment Descriptor.

It contains below tag which will be default executed.

<welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
</welcome-file-list>

You can change default wel-come file list for maintenance hours and restart Web Server.

Answer 2

Define a default landing page in deployment descriptor file. When any visitor visits your page it should land on that page. Don't provide any link to navigate to other pages.
