2) http://host:7778/fagcs_320_C106_sfoaix04/domain/
The submit_form works perfectly fine for second link but not the first one.
I'm getting this error/status "Couldn't submit form:500::500 Server closed connection without sending any data back".
Please guide me as to why it would no work for first case,how do i diagonize the issue?
Please not that,i can manually login to both pages with same usrname and pswd.

use strict; 
use WWW::Mechanize; 

my $url = 'http://host:7777/fagcs_302_C600_sfosun05/domain/'; 
#my $url = 'http://host:7778/fagcs_320_C106_sfoaix04/domain/'; 
my $username = 'usrname'; 
my $password = 'pswd'; 

my $agent = WWW::Mechanize->new(); 
$agent->get ($url); 
#print $agent->content(); 
if($agent->success()){ 
eval { $agent->submit_form ( 
form_number => 0, 
fields => { 
'j_username' => $username, 
'j_password' => $password,

500 implies that there is a server error of some sort. I would check the error.log of the second server. To verify the 500 Server error I would manually attempt to access the web page with the values you are trying to pass. You might be sending what you think you are.

Since you seem to be using autocheck, you should write your program like this

The error "500 Server closed connection without sending any data back" indicates a problem with the server. You should try to see if it works from a browser like Firefox (Firebug), and if it does, you should install livehttpheaders, and compare what firefox sends to what your program(mechanize) sends.

Hello folks, thanks for the replies.
I wasn't able to test the suggestion you provided.
I shall hope to try out your suggestions by EOD tommorow.

My special thanks to the anonymous monk,that is something new to me.

Will update you folks on the same.

Hey folks please help me.
Its a critical task for me now.
Now the script is throwing this error message
"Error POSTing http://host:12501/adhoc_sfosun05/login/login.do"
What should we understand when we get "Error POSTing". I can't seem to get around with this task.
Seems like when script executes submit_form statement than it throws the above message.
Please help me.

If both ports are on the same server, I'ld guess one of them may be a https - port.
Try telnet host 7777 and once connected, type GET / HTTP/1.0 and press ENTER/RETURN twice. Read the reply and try again using the other port.
