CEMEM0001E The object associated with the emitter factory JNDI lookup is empty.

Explanation
The runtime was unable to locate the Common Event Infrastructure (CEI) emitter factory using the Java Naming and Directory Interface (JNDI) location specified.  A likely cause of the problem is that the JNDI location specified in the configuration of the Common Event Infrastructure (CEI) default emitter has a value that is not valid.
User response
In the administrative console, in the configuration of the CEI default emitter, change the JNDI location to a valid value.  For a standalone server this value is usually set to com/ibm/events/configuration/emitter/Default, however in a clustered environment this needs to be set to the CEI server in the cluster that is configured to emit events.
