After you have created a configuration file for a connector and modified it, make sure that the connector can locate the configuration file when the connector starts up.
To do so, open the startup file used for the connector, and verify that the location and file name used for the connector configuration file match exactly the name you have given the file and the directory or path where you have placed it. for more information on the startup file, see the appropriate section of your adapter user guide as well as the User Guide for IBM WebSphere Business Integration Express for Item Synchronization.
