javax.ejb.EJBException: Unable to locate implementation of PegaRULES Engine class for EngineBMT
Steps to Reproduce
Not Applicable
Root Cause
A defect or configuration issue in the operating environment, likely due to the fact that there were messages in the queue during server startup.
Depending on the timing of the message processing, the Pega engine may not be ready, and hence the error described above.
Resolution
Ensure that all the messages in the queue are drained before restarting the server.
