Clientprotocolexception when attempting to submit a request to soap wsdlrequest through Java setting user name and password

My goal is to create a soap UI project with a given WSDL URL, save it and send all requests through Java methods I received org apache. http. client. ClientProtocolException ….. Caused by the following reasons: org apache. http. Protocolexception: when I try to submit a request by setting the user name and password of the operation, an error has occurred in the content length header Find my java method to send the request

public void runSoap() throws Exception
{
        String projectFile = "SoapUIProjects/TestProjectA-soapui-project.xml";
    SoapUI.setSoapUICore(new StandaloneSoapUICore(true));
    WsdlProject project = new WsdlProject(projectFile);

    int c = project.getInterfaceCount();
    System.out.println("The interface count   ="+c);

    for(int i=0;i<c;i++)
    {
        WsdlInterface wsdl = (WsdlInterface) project.getInterfaceAt(i);
        String soapVersion = wsdl.getSoapVersion().toString();
        int opc = wsdl.getOperationCount();
        String result="";

        for(int j=0;j<opc;j++)
        {
            WsdlOperation op = wsdl.getOperationAt(j);
                String opName = op.getName();
                System.out.println("OPERATION:"+opName);

                WsdlRequest req = op.getRequestByName("Req_"+soapVersion+"_"+opName);

                //Assigning correct u/p to an operation: Generate
                if(opName.equals("Generate"))
                {
                    System.out.println("The operation is Generate.");
                    req.setUsername("u1");//Setting username
                    req.setPassword("u1");//Setting password
               }

               WsdlSubmitContext wsdlSubmitContext = new WsdlSubmitContext(req);
               WsdlSubmit<?> submit = (WsdlSubmit<?>) req.submit(wsdlSubmitContext,false);
               Response response = submit.getResponse();
               result = response.getContentAsString();
               System.out.println("The result ="+result);
        }
    }
}
