First you need to setup each tomcat to support this, plus the war app needs to support clustering, otherwise you will need to deploy the war on both tomcats manually.

Read this:

http://www.mulesoft.com/tomcat-clustering
http://tomcat.apache.org/tomcat-6.0-...ter-howto.html
http://www.easywayserver.com/impleme...clustering.htm

If you set the tomcats up like this and deploy the war file only on one of them it should deploy them on all tomcats, but only if the applications supports it, otherwise you can't do it, no matter whats the config.

Quote:
Add distributed tag in web.xml

Next step to do add distributed tag in web.xml to switching session among the tomcat clustering instance

Make any application, e.g we are making cluster as application folder in webapps

1. TomcatA - > webapps - > cluster -> WEB-INF -> web.xml
2. TomcatB - > webapps - > cluster -> WEB-INF -> web.xml
3. TomcatC - > webapps - > cluster -> WEB-INF -> web.xml

Add <distributable /> in all three web.xml file



<?xml version="1.0" encoding="ISO-8859-1"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<distributable />

</web-app>
