FW: stunnel and java ---

Hi
      I am new to stunnel.....I need some help .....i want to write some 
adapter for mycustomer....They opened stunnel for my ipaddress but we did not 
open an stunnel from ourside  (Thats why i am currently using https to connect 
to their site .Once S-tunnel enabled from ourside then i should connect only 
with http ) .So i am currently using  this url in browser.

https://123.456.789.123:12038/lic.cgi?msisdn=+491771234567&serviceid=13&type=getcobyno
 ..i am getting results

but i am unable to get the results if i am using java program ..... 


i am using jdk1.4.1 on windows 2000 ...i hope when we use stunnel there is no 
necessary to send certificates to server for handshake?Then how should i 
proceed.

I am not sure whether i should miss something here....like basic steps to 
enable stunnel.



please find the  source code and exception ...
