Hi,

obviously your client code uses the RMI/IIOP locator policy.
This protocol is not reliable and not usable for production environment.
Therefore the support has been deprecated in MQWF 3.5 and removed in MQWF
3.6.

The reason for your particular error is located outside of the MQWF API.
There seems to be a protocol error in the RMI protocol.
Use the LOC locator policy to logon to MQWF.
The MQWF error codes are described in the Programming Guide.
However RC=100 means Internal Error and does not help much.
