I'm using tomcat 5.5, and for this kind of things i'm creating a xml file in
the {TOMCATHOME}/conf/Catalina/localhost/AppName.xml
With a content like this:
# cat /etc/tomcat-5.5/Catalina/localhost/AppName.xml
<Context path="/AppName" docBase="AppName" debug="5" reloadable="true"
crossContext="true">
        <Resource name="jdbc/conexion" auth="Container"
type="javax.sql.DataSource"
                driverClassName="oracle.jdbc.driver.OracleDriver"
        url="jdbc:oracle:thin:@192.168.1.1:1521:SIDBD" username="scott"
password="tiger"
        maxActiVe="3" maxIdle="1" maxWait="-1" />
</Context>
