Getting a 32-bit COM client for working with a 64-bit server outside the processor using Java / JaCoB

This question indicates that a 32-bit COM client can talk to a 64-bit COM server (and vice versa) if the server is down. I am trying to implement a client using the Java Com Bridge (JaCoB) library so that I can talk to a third-party off-processor server, which should be possible in accordance with this question . The test code used is successfully executed if I map the process architectures (32-bit or 32-bit or 64-bit, 64-bit), but with an error for any cross-combination with this exception:

Exception in thread "main" com.jacob.com.ComFailException: A COM exception has been encountered:
At Invoke of: Execute
Description: Invalid callee.

    at com.jacob.com.Dispatch.invokev(Native Method)
    at com.jacob.com.Dispatch.invokev(Dispatch.java:858)
    at com.jacob.com.Dispatch.callN(Dispatch.java:455)
    at com.jacob.com.Dispatch.call(Dispatch.java:544)
    at com.jacob.activeX.ActiveXComponent.invoke(ActiveXComponent.java:447)
    ...

Any ideas?
