In play1, we can package the project to a war, then put it in a tomcat:
play war
But how to do the same in play2? play war
doesn't work, it reports war
is not a valid task.

It's not still supported, support won't be released until Play 2.1 (as per current plan)
PS: I know your comment says so, but it's better to have it as an answer for people finding this page.
其他提示
as pointed out by @Freewind, officialy, it's not supported, this is because they need the Servlet 3.1 specifications to support all the nice websocket and other advanced features that play2 provides.
However, if you do not use that, there is a plugin on github to provide play war
and be able to deploy on some cloud servers, etc:
https://github.com/dlecan/play2-war-plugin/
WAR Plugin for Play framework 2.0 bring this feature.
This project is a module for Play framework 2 to package your apps into standard WAR packages. It can be used with Servlet 3.0 and 2.5 containers (Tomcat 6/7, Jetty 7/8/9, JBoss 5/6/7, ...)
offered by the official site, if you just want to publish your website, there may be some alternative ways to achieve the goal.
Creating a standalone version of your application
Or, you can use with lighttpd
or nginx
, here is the configuration doc:
Set-up a front-end HTTP server
If you plan to host several applications in the same server or load balance several instances of your application for scalability or fault tolerance, you can use a front-end HTTP server.
