{I already posted this problem deep inside another thread but didn't get an
answer. I'd really like one so I'll try again.)
I have Mathematica 5.2 on Windows XP
While I can import data from the Web from a sufficiently "simple" URL, e.g.
Import["http://public.web.cern.ch/public/";, "Lines"]
I find that when I try a less "simple" URL such as
Import["http://ichart.finance.yahoo.com/table.csv?s=%5EDJI&a=09&b=1&c=2000&d=...","CSV";]
then I just get errors like
Java::excptn: A Java exception occurred: java.io.IOException: The filename,
\
directory name, or volume label syntax is incorrect
at java.io.WinNTFileSystem.createFileExclusively(Native Method)
at java.io.File.checkAndCreate(File.java:1314)

This was the example URL from the earlier posting. Apparently it works fine
for other people. In fact, it also works for me if I switch to a remote
kernel running on a Linux computer.
Can anyone suggest what might be wrong in my setup ? I would really like
to be able to use this kind of data access.
(As mentioned in my earlier post the J/Link example notebook GetURL seems to
work.)
Thanks,
John Jowett
