I know LogSupport classes is missing tried using LogSupport classes , javax.mail and activation-1.0.2, but not finding the  LogSupport classes.

Any idea what could be solution.

Thanks

Hi @murali2425, Were you able to find a solution/workaround to this problem? I am experiencing the same error on the PutEmail processor and can't seem to find a solution.

Hi @murali2425 and @cgag,

probably late but this helped in my case:

<nifi-folder>/lib/java11

try replace

javax.activation-api-1.2.0.jar

with

javax.activation-1.2.0.jar

Thank you so much. That was also the case with my NiFi instance. The replacement of this .jar package saved me lots of time.
