Hi,

We are facing an issue with IBM BPM (BAW) on two separate environments (Office Server & Client Server). Both are experiencing AppCluster failure with the following errors:

[2/24/25 16:58:05:257 PKT] 00000138 BusinessExcep E   CNTR0020E: EJB threw an unexpected (non-declared) exception during invocation of method "start" on bean "BeanId(IBM_BPM_Teamworks_FBLDev.AppCluster#twcore-StartupBeans.jar#NotificationListenerRegistrationStartupBean, null)". Exception data: java.lang.NoClassDefFoundError: com.ibm.bpm.embeddedecm.internal.EmbeddedECMInternalUtils (initialization failure)

javax.ejb.NoSuchEJBException: An error occurred during initialization of singleton session bean IBM_BPM_Teamworks_FBLDev.AppCluster#twcore-StartupBeans.jar#NotificationListenerRegistrationStartupBean, resulting in the discarding of the singleton instance.; nested exception is: javax.ejb.EJBException: See nested exception; nested exception is: java.lang.Exception: See nested Throwable

Troubleshooting Steps Taken:

✔ Restarted BPM & WebSphere servers
✔ Verified JDBC connections – no issues found

Would appreciate any insights or solutions. Thanks in advance!
