Calling secured Web Service

Question

Hi,
I am new in calling web service from PL/SQL block.
From the code I'm successfully able to call non-secured webservice like this "http://www.ignyte.com/webservices/ignyte.whatsshowing.webservice/moviefunctions.asmx?wsdl"
And also by setting the wallet I'm also able to call secured web service like this "https://www.docusign.net/api/3.0/Credential.asmx?WSDL" (ping method).
For calling this secured service I stored certs with chain into the wallet and that works.
But my problem is a different web service where that web service is authenticating me with my certificate. I have VeriSign certificate with private key and that web service has my public key. Whenever I will send SOAP request I need to send my certificate with the request. And communication will be over SSL.
I have created a wallet with complete chain from the PFX file I received from VeriSign and Wallet is in Ready state, also I have included web service's certificate also.
Whenever I am trying to make SOAP call I'm getting
ORA-00600: internal error code, arguments: [kgazmo_1], [], [], [], [], [], [], []
Please let me know where is the problem. May be I'm not able to send my certificate for authentication or may be I'm not able to establish SSL for communication from PL/SQL.
I'm using 10.1.2 as database. I also have 10g AS installed, if that can help in achieving this.
Code is as follows:
FUNCTION CallWS
RETURN xmltype
AS
l_request soap_api.t_request;
l_response soap_api.t_response;
l_url VARCHAR2(32767);
l_namespace VARCHAR2(32767);
l_method VARCHAR2(32767);
l_soap_action VARCHAR2(32767);
l_doc xmltype;
BEGIN
l_url := 'https://secured.webservice.com/WS/WebService.asmx';
l_namespace := 'xmlns="https://secured.webservice.com/WS"';
l_method := 'GetMe';
l_soap_action := 'https://secured.webservice.com/WS/GetMe';
utl_http.set_wallet('file:c:/wallets','pass123');
l_request := soap_api.new_request(p_method => l_method,
p_namespace => l_namespace);
soap_api.add_parameter(p_request => l_request,
p_name => 'param1',
p_type => 'xsd:string',
p_value => 'val1');
soap_api.add_parameter(p_request => l_request,
p_name => 'param2',
p_type => 'xsd:string',
p_value => 'val2');
l_response := soap_api.invoke(p_request => l_request,
p_url => l_url,
p_action => l_soap_action );
l_doc := l_response.doc;
RETURN l_doc;
END CallWS;
You can find SOAP_API package here [SOAP_API|http://www.oracle-base.com/dba/miscellaneous/soap_api.sql] .
Thanks in advance.

Thanks again Billy,
I have configured a wallet with all the necessary certificates. Actually I have purchased a VeriSign trusted certificate and convert that into Oracle Wallet (p12) using openssl with appropriate password. And I'm calling UTL_HTTP.set_wallet('<path_to_wallet>','<pass_to_open_it>');
I have send my public key to them (web service company) and they need me to send my certificate with every request so that they can authenticate.
You are saying we don't have to write any code for TLS/SSL UTL_HTTP will take care of that, thats really good.
One more thing I want to mention here...
In Internet Explorer - When I am importing my certificate without my private key and trying to access web service I'm getting 404 page not found error.
But when I'm importing my certificate with the private key, I can see WSDL and all other methods offered by that web service.
I'm guessing Oracle Wallet that I'm creating with my certificate will store private key also. B'coz it is showing me User Certificate in Ready state.
ORA-00600 is not giving me proper location where I can find any error in my code.
Thanks
