Rapthor-
take a look at http://developer.mimer.com/howto/howto_29.htm
JDBCRealm is a technique for storing user information in a database.

Where JDBCRealm info is accessed via your connection handle (and hopefully 
acquired from connection pool ) defined within server.xml as in this example
<Resource name="jdbc/MimerPool" auth="Container" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/WhateverPoolYouAreUsing">
    <parameter>
        <name>user</name>
        <value>HOTELADM</value>
    </parameter>
    <parameter>
        <name>password</name>
        <value>HOTELADM</value>
    </parameter>
    <parameter>
        <name>driverClassName</name>
        <value>com.mimer.jdbc.Driver</value>
    </parameter>
    <parameter>
        <name>driverName</name>
        <value jdbc:mimer://localhost/UniqueNameForYourDriver</value>
    </parameter>
</ResourceParams

more specifically DataSource is defined within your app's web.xml as in 
<resource-ref>
        <resource-ref-name>jdbc/WhateverPoolYouAreUsing</resource-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
</resource-ref>

To quote mimer.com doc:
JDBCRealm is a technique for storing user information in a database. The first 
step to enable storing user information is to create the necessary tables. 
(The context is where the connection handle is typically stored..)

Context = new InitialContext(); 
Get a data source, for example:
DataSource ds = (DataSource) 
context.lookup("java:comp/env/jdbc/WhateverPoolYouAreUsing"); 
Get a connection, for example:
Connection con = ds.getConnection();
the connection handle will be used to access JDBCRealm information-
