PL/SQL doesn't work with SOAP webservice

Question

PL/SQL SOAP Call doesn't work and i am using Oracle 11g It gives the output like:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org /soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<soapenv:Fault>
<faultcode xmlns:ns1="http://xml.apache.org/axis/">ns1:Client.NoSOAPAction</faultcode>
<faultstring>no SOAPAction header!</faultstring>
<detail>
<ns2:hostname xmlns:ns2="http://xml.apache.org/axis/">testvm564.de.test.com</ns2:hostname>
</detail>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>

And the PL/SQL is(WHICH Works fine in SOAP UI):

declare
soap_request  VARCHAR2(30000);
soap_respond  CLOB;
http_req      utl_http.req;
http_resp     utl_http.resp;
resp          XMLType;
soap_err      exception;
v_code        VARCHAR2(200);
v_msg         VARCHAR2(1800);
v_len number;
v_txt Varchar2(32767);
BEGIN

-- Define the SOAP request according the the definition of the web service being called
soap_request:= '<?xml version = "1.0" encoding = "UTF-8"?>'||
               '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.test.com/dta/TestData/2/0" xmlns:urn="urn:core.bo.service.sim.test.com">'||
               '<soapenv:Header/>'||
               '  <soapenv:Body>'||
               '    <ns:GetRoleAssignmentRequest>'||
               '      <ns:auth>'||
               '      <urn:user>'||'testUser'||'</urn:user>'||
               '      <urn:password>'||'testPass'||'</urn:password>'||
               '      </ns:auth>'||
               '    </ns:GetRoleAssignmentRequest>'||
               '  </soapenv:Body>'||
               '</soapenv:Envelope>';
http_req:= utl_http.begin_request
          ( 'http://test.test.com/testWebService/services/testService20SOAP?wsdl/getRoleAssignment'
          , 'POST'
          , 'HTTP/1.1'
          );
utl_http.set_header(http_req, 'Content-Type', 'text/xml');
utl_http.set_header(http_req, 'Content-Length', length(soap_request));
utl_http.set_header(http_req, 'Download', ''); -- header requirements of particular web service
utl_http.write_text(http_req, soap_request);
http_resp:= utl_http.get_response(http_req);
utl_http.get_header_by_name(http_resp, 'Content-Length', v_len, 1); -- Obtain the length of the response
FOR i in 1..CEIL(v_len/32767) -- obtain response in 32K blocks just in case it is greater than 32K
LOOP
    utl_http.read_text(http_resp, v_txt, case when i < CEIL(v_len/32767) then 32767 else mod(v_len,32767) end);
    soap_respond := soap_respond || v_txt; -- build up CLOB
    dbms_output.put_line('Aneesh'||soap_respond);
END LOOP;
utl_http.end_response(http_resp);
resp:= XMLType.createXML(soap_respond); -- Convert CLOB to XMLTYPE

END;

Please extend your help (I can add the expected output if it is required) (I can add the expected output if it is required)

Add SOAPAction Header to your HTTP request:

utl_http.set_header(http_req, 'SOAPAction', 'yourHeader');

you will find SOAPAction value in service WSDL:

<wsdl:operation name="yourOperation">
  <soap:operation soapAction="yourSoapAction" ... />
