I am just getting started to learn about Web Apps and deploying them to Tomcat. So I started with a sample web app project - made up of struts, hibernate, etc., etc.
The ANT build was successful. Also, was able to deploy the web app through an xml under Catalina/host. I am able to open the web site with no issues.
This is the structure of my web app
-exploded -WEB-INF -classes -lib -web.xml -index.jsp -welcome.html
My question is
How does Tomcat know which is the first page / starting page / home page that it is supposed to open? Which file is this specified in?

ROOT folder has config files for 'Welcome' page for tomcat. You can copy it from the other tar file into ../webapps folder and you'll be good. Symlinking ROOT to your webapp's folder does a great job and adds a little bit more flexibility.
The easiest would be to have the Tomcat home page (TOMCAT_HOME/webapps/ROOT/index. jsp) perform a redirect to your start page. Or, if you have just a single web app, you can move that to the ROOT web app. Thanks a lot for the quick reply.
In any web application, there will be a web.xml in the WEB-INF/ folder.
If you dont have one in your web app, as it seems to be the case in your folder structure, the default Tomcat web.xml is under TOMCAT_HOME/conf/web.xml
Either way, the relevant lines of the web.xml are
<welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list> so any file matching this pattern when found will be shown as the home page.
In Tomcat, a web.xml setting within your web app will override the default, if present.
