How to use action directly on the homepage of the Java EE website project

Before doing some website projects, most of them are home is login, directly into the homepage of not much, also did not notice, today just notice to remember. It's kind of a little trick.

<welcome-file>index.jsp</welcome-file> most people in the beginning to do the site is often configured in webxml so that you can directly use the site root directory to access the home page.

But the problem with this is that if your home page data is from the database (although the data is either cached or static for large sites), then you definitely want to call action directly.

<welcome-file>index.action</welcome-file>

This kind of writing certainly is not good, certainly will have 404.

There are two ways to solve this problem (simple processing)

One way is to write an empty page, as index.jsp, with the JS implementation to jump to the homepage.

Another way is to create a new file under the Webroot directory name is called index.action (blank file on the line)

Then <welcome-file>index.action</welcome-file> this will not cause 404.
