Error publishing endpoint

I have a NetWeaver 7.31 server with a service registry and I'm publishing a service from an ECC 605 system.  The service is active, has an endpoint and I can invoke it using the wsnavigator successfully.  When I publish to the registry from soamanager I get all green lights and messages saying everything was published successfully. However, the endpoint does not show up in the registry.  In the log I get these errors:

followed by:

I assume the second error (which appears to be the reason the endpoint doesn't show up in the registry) is a result of the first.  Can anyone help understand what that first error is?

Thanks,
