BasicDataSource data source usage.

[Anthony Mutiso 2 <an...@utilitynet.net>]

The struts javadoc page for GenericDataSource says to use BasicDataSource.

When I configure a struts data-source with BasicDataSource, my struts 1.1 b2
application fails work with a 

java.sql.SQLException: Cannot load JDBC driver class 'null'

On the appplication startup

While if I remove the "type" attribute all appears well.

This dies
  <data-source key="SiteCatalogDataSource"
type="org.apache.commons.dbcp.BasicDataSource">

This works
  <data-source key="SiteCatalogDataSource">

Why do I want a BasicDataSource? The docs implie that I can do it, and
GenericDataSource's methods are all deprecated.

I wanted to get the at the DriveClassName within the app to print out in the
logs the application configuration.

Thanks

Anthony

Without seeing your nested property setter elements, it's impossible to
know for sure, but I'd bet that you didn't adjust the property names to
match.  For example, in DBCP the JDBC driver class is set by the
"driverClassName"  property, while for GenericDataSource it's
"driverClass".

For backwards compatibility, GenericDataSource in 1.1 is just a wrapper
around BasicDataSource.  The wrapper adapts automatically to the property
name differences, so old 1.0 apps continue to work.
