Issue with line-breaks in SOAPUi-generated request

Hi,

I'm currently working on a webservice using a service provider (javax.xml.ws.Provider).

In order to test it rapidly, it thought about using SOAPUi. The thing is the requests sent by SOAPUi contain line-breaks and for an unknown reason
my service provider doesn't succeed to get the content of the request correctly.

After many testing and internet searches, I finally found that the same request without line-breaks is working whereas with line-breaks it is not.

Is there an option to force the removal of the line-breaks in the RAW version of the request in SOAPUi ?

OR

Is there something to do in my code to make it able to correctly work?

Thank you for any indication!

Here is a part of my code :

@WebServiceProvider(portName = "serviceSOAP", serviceName = "service", targetNamespace = "http://www.example.net/")
@ServiceMode(value = javax.xml.ws.Service.Mode.MESSAGE)
public class ServiceIO implements Provider<SOAPMessage> {

 private static Logger log = Logger.getLogger(ServiceIO.class);

 @Override
 public SOAPMessage invoke(SOAPMessage request) {
   try {
    
    request.writeTo(System.out); //Here I'm checking if the request arrived correctly
 
    Node root = request.getSOAPBody().getFirstChild(); // Getting the real message from the SOAPMessage,
                  // IT DOESN'T WORK IF THE MESSAGE COMES FROM SOAPUI

    String operation = root.getLocalName();

    if (operation == null) { //The operation is always null if the request is not "inline"
     log.debug("invoke Exception : no operation name");
     throw new ServiceIOFault("No Operation Name");
    }
                                else{
                                       System.out.println("Operation : "+operation);
                                }
                     }catch(Exception e){
                                e.printStackTrace();
                     }
            }
}
