Web service call from pl/sql 10g

Question

I am having problems in calling a web service from pl/sql. This is what I followed
Here is my wsdl
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://svc" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://svc" xmlns:intf="http://svc" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<wsdl:types>
<schema elementFormDefault="qualified" targetNamespace="http://svc" xmlns="http://www.w3.org/2001/XMLSchema">
<element name="name" type="xsd:string"/>

</wsdl:types>
<wsdl:message name="getGreetingResponse">
<wsdl:part element="impl:getGreetingReturn" name="getGreetingReturn"/>
</wsdl:message>
<wsdl:message name="getGreetingRequest">

<wsdl:part element="impl:location" name="location"/>
</wsdl:message>
<wsdl:portType name="PlsqlS">

</wsdl:portType>
<wsdl:binding name="PlsqlSSoapBinding" type="impl:PlsqlS">

</wsdl:input>
<wsdl:output name="getGreetingResponse">

</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="PlsqlSService">
<wsdl:port binding="impl:PlsqlSSoapBinding" name="PlsqlS">
<wsdlsoap:address location="http://myServer:7001/plsqlsvc/services/PlsqlS"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
Here is my pl/sql
package body pkg_my_webservice as
vg_funciton_fnc VARCHAR2(256) := 'getGreeting';
vg_ws_address VARCHAR2(255) := 'http://myServer:7001/plsqlsvc/services/PlsqlS';
FUNCTION call_myfuntion(
vp_parameter1 VARCHAR2,
vp_parameter2 VARCHAR2)
RETURN VARCHAR2 AS
ol_req soap_api.t_request;
ol_resp soap_api.t_response;
BEGIN
-- we initilize a new request
ol_req := soap_api.new_request(vg_funciton_fnc,
'xmlns="' || vg_ws_address || '"');
-- we started to add parameters
soap_api.add_parameter(ol_req,'name', 'partns:string',
vp_parameter1);
soap_api.add_parameter(ol_req,'location', 'partns:string',
vp_parameter2);
ol_resp := soap_api.invoke(ol_req, vg_ws_address, vg_funciton_fnc);
-- we get back the results
RETURN soap_api.get_return_value(ol_resp, 'getGreetingReturn', -- result tag name
'xmlns:m="' || vg_ws_address || '"');
exception WHEN others then
dbms_output.put_line ( Utl_Http.get_detailed_sqlcode || Utl_Http.Get_Detailed_Sqlerrm);
return 'exception happened';
END call_myfuntion;
end pkg_my_webservice;
Here is the error

It was found out that the server port was not open from the data-tier.
