Hi Xiwei,

Are you behind a firewall?
Keep in mind that the current biomaRt will try to do MySQL queries to 
the databases,
if you are behind a firewall then these queries won't go through and you 
get the error you show.
You can either ask your systems to enable mysql queries or install a 
local version of the BioMart database you want to query with biomaRt.

best,
Steffen

On which platform are you working? Do you have the XML package installed?
