Last updated on SEPTEMBER 04, 2018

Applies to:

Web Services - Version and later
Information in this document applies to any platform.


A web service proxy generated using JPublisher calls a web service developed in-house.

After working for sometime, the following exception begins to occur with the callout:
ORA-29532: Java call terminated by uncaught Java exception: java.rmi.RemoteException: java.rmi.RemoteException:cannot locate service implementation class for service: package1.MyOutWSService_Impl (HugeClob) 3
The error occurs intermittently.  The services callouts work fine almost all the time.  Even when the error occurs, users can workaround the issue by closing the current connection and opening a new one.
