RE: ClassCastException in IFSFile

>From this trace and stack trace, it appears that your as-file server is
returning a data stream that is not expected by your JTOpen client.
Unfortunately, without a comm trace, it's difficult to tell exactly what
that is.  Even if we had a comm trace, since I don't know the exact format
of the messages passed to and from the as-file server, I really couldn't
help without major digging into the JTOpen guts.

I would suggest that you contact IBM and make sure that you're up to date on
your TCP/IP and host server PTFs.  From the archived posting that you
mention, it sounds like the as-file server is returning bad information and
that perhaps that was corrected in some maintenance.

Sorry I can't be of more help.
