There is nothing wrong with that code snippet.
But the actual output depends upon what options
you have used when loading the Xy-pic package,
and how you are viewing that output.

Are you using a PostScript back-end?
If so, then arrowheads may not appear in a DVI-viewer,
but will be in the PostScript or PDF document,
after doing a standard conversion to these formats.

In the absence of seeing your full LaTeX source file,
the .log file for your job should indicate whether you are
using a PostScript back-end, by showing which support files
have been loaded, and with some other messages perhaps.

Please reply to the Xy-pic mailing list, copied on this reply,
so that others may be able to help you sooner than myself.
