The tomcat.conf configuration file for tomcat RPMs has an invalid javax.sql.DataSource.Factory set by default. Attempting to use the Factory would cause a CNFE, but causes no adverse issues unless users try to use it.

The property should be updated to javax.sql.DataSource.Factory=org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory instead to point to the correct BasicDataSourceFactory class and commented out as it is really just an example and is already the default factory that tomcat uses.
