GlobalNamingResources?
I sent up a data source for each app, like this:
<Context    path="/api-prototype"
            docBase="api-prototype.war"
            debug="1"
            reloadable="true"
            crossContext="true"
            useNaming="true">
    <Logger className="org.apache.catalina.logger.FileLogger"
            prefix="localhost-api-prototype-log."
            suffix=".txt"
            timestamp="true"/>
    <Resource   name="jdbc/APIPrototype"
                auth="Container"
                type="javax.sql.DataSource"/>
<!-- Oracle 9.2.0.1 data source -->
    <ResourceParams name="jdbc/APIPrototype">
        <parameter>
            <name>factory</name>
            <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
        </parameter>
        <parameter>
            <name>driverClassName</name>
            <value>oracle.jdbc.driver.OracleDriver</value>
        </parameter>
        <parameter>
            <name>url</name>
            <value>jdbc:oracle:thin:@elvis:1521:CAPP</value>
        </parameter>
        <parameter>
            <name>username</name>
            <value>api</value>
        </parameter>
        <parameter>
            <name>password</name>
            <value>mod</value>
        </parameter>
        <parameter>
            <name>maxActive</name>
            <value>20</value>
        </parameter>
        <parameter>
            <name>maxIdle</name>
            <value>0</value>
        </parameter>
        <parameter>
            <name>maxWait</name>
            <value>60000</value>
        </parameter>
        <parameter>
            <name>removeAbandoned</name>
            <value>true</value>
        </parameter>
        <parameter>
            <name>removeAbandonedTimeout</name>
            <value>300</value>
        </parameter>
    </ResourceParams>
</Context>This works fine on Tomcat 4.1.24. I don't know where you got that example from, but I'd recommend that you look at the Tomcat JNDI How-to:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html
Why go anywhere else? - MOD
