Tomcat documentation states:
If the web application is packaged as a WAR then /META-INF/context.xml will be copied to $CATALINA_BASE/conf/ [enginename] / [hostname] / and renamed to match the application's context path .
For a Maven project, put context.xml in src/main/webapp/META-INF/ .

For Tomcat 6, there's no default manager username and password. You do have to set it up yourself, though it's pretty straightforward. The Tomcat manager webapp is restricted to users with a role named manager . So you'll need to create a user and assign the manager role to it.
Edit $CATALINA_BASE/conf/tomcat-users.xml to read:
<?xml version='1.0' encoding='utf-8'?>
<!--
...
For tomcat 7:
<tomcat-users>
<role rolename="manager"/>
