How Can I Deploy a Tomcat Application to the Web Root?

Deploying Application at the Web Root in Tomcat

When deploying war files in Tomcat, they are typically accessible via a URL pattern like http://localhost:8080/war_name/application_name. However, there are instances where you may want your application to be accessible at the root level of the domain, without the need for a supplementary directory.

To achieve this, there are two primary approaches.

Modifying Configuration and Renaming WAR File

One option is to remove the pre-existing ROOT directory from Tomcat and rename your war file to ROOT.war before deploying it. This effectively replaces the default ROOT application with your own war file.

Configuring Context Root in server.xml

Alternatively, you can deploy your war file under a different name, such as war_name.war. Modify the conf/server.xml configuration file and add the following context root within the element:

<context path="" docbase="war_name" debug="0" reloadable="true"></context>

This configuration redirects the default root context to your war file.

The first approach is simpler but may involve additional modifications; the second approach is more customizable and allows you to access your application using a different name. Choose the method that best suits your requirements.
