Deploying my application at the root in Tomcat

Question

I have the war file of my application. I need to deploy this at the root level. The current URL is http://localhost:8080/war_name/application_name.

Answer 1

The fastest way.

1. Make sure you don't have ROOT app deployed, undeploy if you have one

2. Rename your war to ROOT.war, deploy, thats all, no configuration changes needed

Answer 2

You have a couple of options:

1. Remove the out-of-the-box ROOT/ directory from tomcat and rename your war file to ROOT.war before deploying it.

2. Deploy your war as (from your example) war_name.war and configure the context root in conf/server.xml to use your war file :

   <Context path="" docBase="war_name" debug="0" reloadable="true"></Context>
   

The first one is easier, but a little more kludgy. The second one is probably the more elegant way to do it.

Answer 3

In tomcat 7 with these changes, i'm able to access myAPP at / and ROOT at /ROOT

<Context path="" docBase="myAPP">
     <!-- Default set of monitored resources -->
     <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
<Context path="ROOT" docBase="ROOT">
     <!-- Default set of monitored resources -->
     <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>

Add above to the <Host> section in server.xml

Answer 4

In my server I am using this and root autodeploy works just fine:

   <Host name="mysite" autoDeploy="true" appBase="webapps" unpackWARs="true" deployOnStartup="true">
        <Alias>www.mysite.com</Alias>
        <Valve className="org.apache.catalina.valves.RemoteIpValve" protocolHeader="X-Forwarded-Proto"/>
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
           prefix="mysite_access_log." suffix=".txt"
           pattern="%h %l %u %t &quot;%r&quot; %s %b"/>
        <Context path="/mysite" docBase="mysite" reloadable="true"/>
    </Host>
