In my server I am using this and root autodeploy works just fine       lt Host name  mysite  autoDeploy  true  appBase  webapps  unpackWARs  true  deployOnStartup  true  gt           lt Alias gt www mysite com lt  Alias gt           lt Valve className  org apache catalina valves RemoteIpValve  protocolHeader  X-Forwarded-Proto   gt           lt Valve className  org apache catalina valves AccessLogValve  directory  logs             prefix  mysite access log   suffix   txt             pattern   h  l  u  t  amp quot  r amp quot   s  b   gt           lt Context path   mysite  docBase  mysite  reloadable  true   gt       lt  Host gt

You have a couple of options    Remove the out-of-the-box ROOT  directory from tomcat and rename your war file to ROOT war before deploying it  Deploy your war as  from your example  war name war and configure the context root in conf server xml to use your war file     lt Context path    docBase  war name  debug  0  reloadable  true  gt  lt  Context gt     The first one is easier  but a little more kludgy  The second one is probably the more elegant way to do it

Remove  CATALINA HOME webapps ROOT  Update  CATALINA HOME conf server xml  make sure that Host element look like the following text    lt Host name  localhost   appBase  webapps        unpackWARs  true  autoDeploy  false  deployOnStartup  false  gt     lt Context path    docBase  myApp  gt  lt  Context gt    It works with Tomcat 8  autoDeploy and deployOnStartup need to set to false to prevent tomcat from deploying myApp twice

on tomcat v 7  vanilla installation   in your conf server xml add the following bit towards the end of the file  just before the  lt  Host gt  closing tag    lt Context path    docBase  app name  gt       lt  -- Default set of monitored resources -- gt       lt WatchedResource gt WEB-INF web xml lt  WatchedResource gt   lt  Context gt    Note that docBase attribute  It s the important bit  You either make sure you ve deployed app name before you change your root web app  or just copy your unpacked webapp  app name  into your tomcat s webapps folder  Startup  visit root  see your app name there

I know that my answer is kind of overlapping with some of the other answer  but this is a complete solution that has some advantages  This works on Tomcat 8    The main application is served from the root The deployment of war files through the web interface is maintained  The main application will run on port 80 while only the admins have access to the managment folders  I realize that  nix systems require superuser for binding to 80  but on windows this is not an issue     This means that you only have to restart the tomcat once  and after updated war files can be deployed without a problem   Step 1  In the server xml file  find the connector entry and replace it with    lt Connector      port  8080      protocol  HTTP 1 1      connectionTimeout  20000      redirectPort  8443    gt    lt Connector     port  80      protocol  HTTP 1 1      connectionTimeout  20000      redirectPort  8443    gt    Step 2  Define contexts within the  lt Host     gt  tag    lt Context path     docBase  CAS  gt       lt WatchedResource gt WEB-INF web xml lt  WatchedResource gt   lt  Context gt   lt Context path   ROOT  docBase  ROOT  gt       lt WatchedResource gt WEB-INF web xml lt  WatchedResource gt   lt  Context gt   lt Context path   manager  docBase  manager  privileged  true  gt       lt WatchedResource gt WEB-INF web xml lt  WatchedResource gt   lt  Context gt   lt Context path   host-manager  docBase  host-manager  privileged  true  gt       lt WatchedResource gt WEB-INF web xml lt  WatchedResource gt   lt  Context gt    Note that I addressed all apps in the webapp folder  The first effectively switch the root and the main app from position  ROOT is now on http   example com ROOT and the the main application is on http   example com   The webapps that are password protected require the privileged  true  attribute   When you deploy a CAS war file that matches with the root   lt Context path     docBase  CAS  gt  you have to reload that one in the admin panel as it does not refresh with the deployment   Do not include the  lt Context path   CAS  docBase  CAS  gt  in your contexts as it disables the manager option to deploy war files  This means that you can access the app in two ways  http   example com  and http   example com APP   Step 3  In order to prevent unwanted access to the root and manager folder  add a valve to those context tags like this    lt Context path   manager  docBase  manager  privileged  true  gt       lt WatchedResource gt WEB-INF web xml lt  WatchedResource gt       lt Valve className  org apache catalina valves RemoteAddrValve          addConnectorPort  true          allow  143  21  2   d  8080 127  0  0  1 8080   1 8080 0 0 0 0 0 0 0 1 8080   gt   lt  Context gt    This essentially limits access to the admin web app folder to people from my own domain  fake IP address  and localhost when they use the default port 8080 and maintains the ability to dynamically deploy the war files through the web interface   If you want to use this for multiple apps that are using different IP addresses  you can add the IP address to the connector  address  143 21 2 1     If you want to run multiple web apps from the root  you can duplicate the Service tag  use a different name for the second  and change the docbase of the  lt Context path     docBase  CAS  gt  to for example  lt Context path     docBase  ICR  gt

open tomact manager url  - http   localhost 8080 manager html   then in applications you see a application having path as     is deployed  simply Undeploy this   Rename your application s war file as ROOT war and just place at path  - C  Program Files Apache Software Foundation Tomcat 8 5 webapps start your Tomcat No extra configuration needed  Now we can see our application home page or configured url at http   localhost 8080
