Diagnostic JAR File for Data Source Connection Issues
This TechNote provides a diagnostic JAR file that enables ColdFusion MX to provide the proper error message for any issue preventing a successful connection to the data source. This diagnostic tool is included in ColdFusion MX Updater Release 3 or higher, so you don't need to download in this TechNote if Updater 3 or MX 6.1 has been installed.
