Cause
This error occurs if JADE attempts to access a method (typically an external method) and the method has an undefined (null) library.
The definition of methods without a library is not permitted.
Details of the error (including the method name and the type on which it is defined) are written to the JADE messages log file (jommsg.log).
Action
Recompile the method. If the problem persists, this error can indicate an internal JADE error, and you should contact your local JADE support center or JADE Support if your JADE licenses include support.
