Apparant java catch-22

[Gene]

I've been trying to get java installed for some months now and I can't
get past the point shown below. It seems that the port is looking for an
already installed version of java. I've looked at various how-tos, and
the java pages at freebsd.org, but no help. Is there some way around
this catch-22?

Thanks
