Using something like Cayenne for easy to use data access ... 
(http://www.objectstyle.org/cayenne/)

or 

You could use environmental entries in the web.xml:

    <env-entry>
       <env-entry-name>adminUsername</env-entry-name>
       <env-entry-value>admin</env-entry-value>
       <env-entry-type>java.lang.String</env-entry-type>
    </env-entry>

    <env-entry>
        <env-entry-name>adminPassword</env-entry-name>
        <env-entry-value>xxxxxxxxx</env-entry-value>
        <env-entry-type>java.lang.String</env-entry-type>
    </env-entry>

Then get them in your code by using .....

        String adminUsername = "";
        String adminPassword = "";

        javax.naming.Context ctx = null;

        try {
            ctx = new javax.naming.InitialContext();
            if (ctx == null) {
                System.out.println("Context is null in web.xml");
            }
        } catch (Exception e) {
            System.out.println(e);
        }

        try {

            adminUsername = (String) 
ctx.lookup("java:comp/env/adminUsername");
            adminPassword = (String) 
ctx.lookup("java:comp/env/adminPassword");

        } catch (Exception e) {
            System.out.println(e);
        }

or you could research how to read values from an xml file,  something 
which is not really related to Tapestry.
