Queue Processor does not recognize the External class



An external class is imported to the RSI codeset and is referenced in an Activity step. The activity fails when run through a Queue Processor. The activity compiles and runs correctly when executed directly.

Error Messages

java.lang.NoClassDefFoundError: com/rs/es/security/EsSecurityFactory

Steps to Reproduce

  1. Import a third-party JAR.
  2. Reference the external classes in the Java step of an activity.
  3. Execute the activity using a Queue Processor.

Root Cause

A defect or configuration issue in the operating environment.
The Util nodes where the Queue Processor runs, are not restarted after the external classes JAR file is imported.


As a local-change, restart all the nodes.
