Class not present on classpath (invalid class name)

Suggest edit
Updated on April 5, 2022

The Class not present on classpath (invalid class name) exception appears if a custom stream processing configuration is incorrect for a File data set.

Sample message:

com.pega.bigdata.dataset.file.repository.streamprocessing.CustomStreamProcessingInvalidException: Class com.pega.bigdata.dataset.fidf configured for stream processing was not found on classpath

Solution

  1. Verify that the class name that is configured in the File data set matches the class name that you implement in the .jar file.
  2. Ensure that your class definition is available on the classpath on every server node.
  3. If you upload your .jar file (codeset) into the Pega-EngineCode codeset, use the codeset version that the release supports.
