Zimbra.web.xml.in ZimbraAdmin.web.xml.in and Tomcat

[xxtigerxx]

I am new to zimbra and I am very excited about this product it seems like a great suite. I am just trying to figure out how all the pieces work together. It appears to me that you are using the zimbra.web.xml.in and ZimbraAdmin.web.xml.in files intestead of web.xml file to set the Welcome-file for Tomcat.

Zimbra.web.xml.in
<welcome-file-list>
<welcome-file>public/Login.jsp</welcome-file>
</welcome-file-list>

Zimbraadmin.web.xml.in
<welcome-file-list>
<welcome-file>public/Login.jsp</welcome-file>
<welcome-file>public/admin.jsp</welcome-file>
</welcome-file-list>

I cannot find reference to these two files anywhere so my questions are.
First of all is this correct that these files set the welcome file-list instead of web.xml, and

secondly if it is correct then how is tomcat directed to use these files, and

finally it looks like the web.xml file is used and then one or the other of the web.in files. This choice of web.in files I assume, is dependent weather the user is loging into the mail suite or the admin suite. Where is the IF THEN to choose which web.in file to use.

Thanks any help would be appreciated.

These files are templates. When you start tomcat the start scripts put them in place named as web.xml
