To use a JDBC driver that is not included with ColdFusion MX 7 (such as SQLAnywhere or PostgreSQL) you must configure it and add a data source for it.
For more information, see Managing ColdFusion MX 7.
Note: In Windows, ensure that you restart all of the ColdFusion MX 7 services; these are listed in Overview of services.
For more information, see the chapter on data source management in Configuring and Administering ColdFusion MX.
You can now connect to an external JDBC Type 4 data source.
