UTL_DBWS – Consuming Web Services…


I was messing around with the UTL_DBWS package when Oracle 10g was first released and I must admit, I completely missed the point. The other day I came across my draft article and with some fresh eyes noticed what I was doing wrong. So here it is:

UTL_DBWS – Consuming Web Services in Oracle 10g

  1. Hi,

    I am trying to consume a web service using the utl_dbws package. I am getting the following error:

    port: does not contain operation: Envelope
    at oracle.j2ee.ws.client.dii.ConfiguredCall.configureCall(ConfiguredCall.java:154)

    This is the way I am making a call:

    l_namespace :=
    ‘http://my url’;
    l_service_qname :=
    SYS.UTL_DBWS.to_qname (l_namespace, ‘myService’);
    l_port_qname :=
    SYS.UTL_DBWS.to_qname (l_namespace, ‘myServiceEndpointPort’);
    l_operation_qname := SYS.UTL_DBWS.to_qname (l_namespace, ‘check’);
    l_service :=
    (wsdl_document_location => urifactory.geturi
    service_name => l_service_qname

    l_call :=
    SYS.UTL_DBWS.create_call (service_handle => l_service,
    port_name => l_port_qname,
    operation_name => l_operation_qname);

    SYS.UTL_DBWS.set_property (l_call, ‘SOAPACTION_USE’, ‘TRUE’);
    SYS.UTL_DBWS.set_property (l_call, ‘SOAPACTION_URI’, ”);
    SYS.utl_dbws.set_property(l_call, ‘OPERATION_STYLE’, ‘DOCUMENT’);

    sys.utl_dbws.set_property(l_call, ‘ENCODINGSTYLE_URI’, ‘http://schemas.xmlsoap.org/soap/encoding/’);

    sys.utl_dbws.to_qname(‘http://www.w3.org/2001/XMLSchema’, ‘string’);
    ws_request_xml :=
    SYS.XMLTYPE.createxml (create_xml (control_nb,
    –DBMS_OUTPUT.put_line (ws_request_xml.getstringval);
    ws_response_xml := SYS.UTL_DBWS.invoke (l_call, ws_request_xml);
    DBMS_OUTPUT.put_line (‘3*****************’);
    — call_handle => l_call,
    — input_params => l_input_params);
    SYS.UTL_DBWS.release_call (call_handle => l_call);
    SYS.UTL_DBWS.release_service (service_handle => l_service);
    DBMS_OUTPUT.put_line (ws_response_xml.getstringval);

  2. Hi sridevi,

    I am going through your post , i have some questions .. what does the below function do in your post :

    SYS.XMLTYPE.createxml (create_xml (control_nb,

    Will it create xml documnet…..

  3. It’s not my code. I have no idea what it will do. 🙂

    I assume the “create_xml” function is a custom written function returns some XML, that is then passed to the “XMLTYPE.createxml” function to convert the XML document into an XMLTYPE.

    But as I said, it’s not my code so I have no idea about it.



  4. I can’t seem to call this (or any other) web service from Oracle. I get the following error message. (The first couple of lines are in Swedish, and are telling me politely that I have an error and an uncaught java exception). Does anyone know what may be causing this?
