How to set context path in Tomcat 8

I have a war file named FooBar.war, now I want to set context path "/" point to this web apps. It means Users can access the webapp via URL: localhost:8080/ To do that I add a file called ROOT.xml in <catalina_home>/conf/Catalina/localhost/with content

<Context docBase="/opt/mywebapps/FooBar" path="" reloadable="true" />

And I also put FooBar.war into folder /opt/mywebapps/ then set all permissions for this folder:

chmod -R 777 /opt/mywebapps/

After starting Tomcat server, the server can not deploy the war file:

<Context docBase="/opt/mywebapps/FooBar" path="" reloadable="true" />

And I also put FooBar.war into folder /opt/mywebapps/

Note that you now have /opt/mywebapps/FooBar.war, while you're referencing /opt/mywebapps/FooBar. (note the difference in ".war")

As you're not in Tomcat's own webapps folder, where (with the default configuration) WAR files will be automatically unzipped, Tomcat just signals that the location that you've configured simply doesn't exist.
