Cannot create JDBC driver of class '' for connect URL 'null'

[David McMinn]

Tomcat Server 5.5.15 - I searched for solutions and most mention a Context 
element in the server.xml.

I only have a DefaultContext tag within with I have my resouce tag:

<DefaultContext>
 <Resource 
                auth="Container" 
                driverClassName="com.mysql.jdbc.Driver" 
                logAbandoned="true" 
                maxActive="100" 
                maxIdle="30" 
                maxWait="10000" 
                name="jdbc/wroxTC5" 
                password="everypass" 
                removeAbandoned="true" 
                removeAbandonedTimeout="300" 
                type="javax.sql.DataSource" 
                
url="jdbc:mysql://localhost:3306/everycitizen?autoReconnect=true" 
                username="everyuser" 
        />
 </DefaultContext>

The actual failure is on the connection = ds.getConnection(); line in the jsp 
if that helps any.
