java.lang.ClassNotFoundException at runtime when trying to run an MFT Custom Callout (Doc ID 2270836.1)

Last updated on MAY 15, 2023

Applies to:

Oracle Managed File Transfer - Version and later
Information in this document applies to any platform.


When MFT tries to invoke a Custom Callout for file preprocessing, it fails with a ClassNotFoundException.

This happens even though the necessary jar file, and config XML file, are correctly located in the configured MFT Server Properties -> Callout Directory :-

If the same files are copied to a different directory, eg. /tmp (and the MFT Server Properties -> Callout Directory configured appropriately) then the custom callout can be called by MFT successfully.
