Thanks, I'll give it a try.  I think that's the one combination I have 
*not* tried yet.  :-)

This worked for us.

Problem defining JNDI data source.

2005-09-26 Thread David C. Hicks 
I'm having difficulty defining a JNDI data source using C3P0 pooling in 
Tomcat 5.5.9.  Here is the context descriptor for my app:



   verbosity="4" timestamp="true"/>
   reloadable="true" debug="1"/>

   


Here is the resource-ref portion of my application descriptor:

 
 Database Connection
   jdbc/EmsDb
   javax.sql.DataSource
   Container
 

And here is the error I get from Tomcat when deploying the application:
2005-09-27 00:55:33,559 [http-8080-Processor25] ERROR 
JDBCExceptionReporter - Cannot create JDBC driver of class '' for 
connect URL 'null'


It almost seems as if the resource-ref is somehow overriding the 
Resource definition in the application context.

Any suggestions?

Thanks,
Dave
