javax.sql.DataSource

[Justin Chu]

If the above class is just an interface, how is it that I can specify javax.sql.DataSource in tomcat's server.xml file as follows

<Resource name="jdbc/PortalDb" auth="Container" type="javax.sql.DataSource"/>    
               <ResourceParams name="jdbc/TestDb">
                        <parameter>
                                <name>user</name>
                                <value>Tester</value>
                        </parameter>
                        <parameter>
                                <name>password</name>
                                <value>Tester</value>
                        </parameter>
                        <parameter>
                                <name>driverClassName</name>
                                <value>com.sybase.jdbc2.jdbc.SybDriver</value>
                        </parameter>
                        <parameter>
                                <name>driverName</name>
                                <value>jdbc:sybase:Tds:test.com:5000/chutan</value>
                        </parameter>
                </ResourceParams>

I'm not an expert with the tomcat config files but from what I know the Resource tag specifies a resource to be stored/available from a JNDI lookup. Just like in RMI, the type of the object returned is the type of the interface that the object implements.
hope that helps
