Cause
This error occurs when a reference is made to an entry point that is not exported from the Dynamic Link Library (DLL). This occurs when a class is being opened and one of its methods or database methods is not defined in the DLL associated with the method.
Some platforms support a reduced feature set and are shipped without some of the usual JADE DLLs. This error could occur is you attempt to use a feature that is not available on these platforms.
Action
Ensure that the external method or function specifies the correct entry point name. If the entry point name is correct, check that the DLL contains an entry point of the specified name and that it is exported.
Refer to the JADE messages log file (jommsg.log) for information that will help identify the library, entry point, and externalMethod involved.
