[Bioperl-l] How to set the proxy information?

[weiych@sina.com]

Sorry, I made a mistake in the subject.

Hi,
I am a newbie behind my firewall and have to use proxy 
for utilize bioperl. 
I wander whether the LWP support in Bio::DB::WebDBSeqI 
really work. As the doc of Bio::DB::WebDBSeqI noted, I
modified the examples/getGenBank.pl as the following:

...
use Bio::DB::GenBank;
use Bio::SeqIO;

my $gb = new Bio::DB::GenBank;
# $gb->proxy(['http'.'ftp'],'http://xx.xx.xx.xx:8080');
# or
$gb->ua->proxy(['http'.'ftp'], 'http://xx.xx.xx.xx:8080');
# or $gb->proxy(['http'.'ftp'],'http://usrname:passwd@xx.xx.xx.xx:8080'); 
...

But it did not work at all.
The error message is presented here:
[eacheon@neuro examples]$ perl getGenBank.pl

I tried a long time, but can not figure out how to establish
the connection with GenBank. Anyone can help me?
