SQL & PL/SQL :: Error Occurred Calling A Web Service Using UTL_HTTP

I'm calling a web service with HTTPS protocol from a pl/sql program and i'm using the UTL_HTTP package for do this.

I have a Oracle DB installation 11g Enterprise Edition Release 11.2.0.1.0 on my personal computer with a Windows XP OS, and when i run the code it works fine and returns the result I expect. But, when i run the same code on the Oracle DB of my work (Oracle 10g Enterprise Edition Release 10.2.0.4.0 and OS HP-UX) it fails and give me an error, i think that the error has to do with the configuration of the wallet and the certificates in it, because i consume the WS from Os prompt using the command WGET and works fine and i test consuming a WS with HTTP no secure and works fine too.

This is the code and the result in the Oracle DB 11g on my computer:

Connected to Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
Connected as oe@oRCL

SQL>
SQL> declare
2 v_debug_mode boolean := false;
3 v_req utl_http.req;

[Code]....

PL/SQL procedure successfully completed

SQL>

And this is the code(Is the same, the only difference is the path of the wallet) and the error resultant:

Connected to Oracle Database 10g Enterprise Edition Release 10.2.0.4.0
Connected as gpacheco@acseld

SQL>
SQL> declare
2 v_debug_mode boolean := false;
3 v_req utl_http.req;
