PLSQL Procedure to invoke WebService

Question

Hi,
We have a requirement to invoke a webservice(ESB\BPEL) using PLSQL Procedure.
we are trying to invoke service by getting details of service from a table like WSDL path, SOA Envelope and operation type.
If anybody has worked on the same requirements, please let us know ASAP.
With Regards,
Thanks

we did some tests last week and we came up with this (I hope it helps) we are 10g so utl_dbws was already installed
function our_calculator(p_operator in varchar2,p_operand_1 in number,p_operand_2 in number)
  return number as
  the_service    sys.utl_dbws.service;
  the_call       sys.utl_dbws.call;
  the_url        constant varchar2(256) := 'http://.../demo/soap/calculator_server.wsdl';
  service_name   constant sys.utl_dbws.qname := sys.utl_dbws.to_qname(null,'calculator_serverService');
  operation_name constant sys.utl_dbws.qname := sys.utl_dbws.to_qname(null,'calculator_server');
  input_params   sys.xmltype;
  the_result     sys.xmltype;
begin
  the_service := sys.utl_dbws.create_service(urifactory.geturi(the_url),service_name);
  the_call := sys.utl_dbws.create_call(the_service,null,operation_name);
  sys.utl_dbws.set_property(the_call,'OPERATION_STYLE','document');
  input_params := sys.xmltype('<calculator xmlns="' || the_url  || '">
                                 <op>'||p_operator||'</op>
                                 <p1>'||to_char(p_operand_1,'999999999.99')||'</p1>
                                 <p2>'||to_char(p_operand_2,'999999999.99')||'</p2>
                               </calculator>');
  the_result := sys.utl_dbws.invoke(the_call,input_params);
  the_result := the_result.extract('//n:ret/text()','xmlns:n="' || the_url  || '"');
  sys.utl_dbws.release_call(the_call);
  sys.utl_dbws.release_service(the_service);
  return to_number(the_result.getstringval(),'999999999.99');
end;
