Programmatically call ADF Webservice (dynamic Call)

Question

Hi All,
My requirement is to call/Invoke a webservice(Sync ADF Webservice) in ApplicationModuleImpl Class. The service WSDL name & method name are sent to my method as params.
how to invoke it programmatically?
Note: These params are known at runtime only. And there are many services  in Dev environment.
Thanks in Advance.

Hello,
Here is an example of a utility that I use to submit SOAP requests dynamically.  Focus on the createSOAPRequest() and sendRequest() methods.  The execute method is used for implementing this object as a Quartz Job.
The execute() method contains several getString method calls - this is what makes the requests dynamic:
            String endpointUrl = dataMap.getString("endpointUrl");
            String soapAction = dataMap.getString("soapAction");
            String requestXml = dataMap.getString("requestXml");
            String resultPath = dataMap.getString("resultPath");
Here are examples of what would be in each of these strings:
endpointUrl -  http://hostname:port/endpointurl
requestXml -
<soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
    <soap:Body>
        <ns1:process xmlns:ns1=""http://xmlns.oracle.com/yournamespace"">
            <ns1:input />
        </ns1:process>
    </soap:Body>
</soap:Envelope>
resultPath - result
soapAction - process
