javax (jws) WebService, get String of the input parameters (Password: value)

Hello!

I have a set of services in Java, that I call them by SOAP and I want to register the input parameters. For example: 

@WebMethod(operationName = "getObject")
public MyObject getObject(
        @WebParam(name = "param1") final Short param1,
        @WebParam(name = "param2") final Short param2,
        @WebParam(name = "param3") final Short param3,
        @WebParam(name = "param4") final Short param4,
        @WebParam(name = "param5") final Short param5,
        @WebParam(name = "param6") final Short param6,
        @WebParam(name = "param7") final Integer param7,
        @WebParam(name = "param8") final String param8,
        @WebParam(name = "param9") final Date param9,
        @WebParam(name = "param10") final Date param10,
        @WebParam(name = "param11") final Date param11,
        @WebParam(name = "param12") final Date param12)

Once in the function I do this to collect and save in a log file what I have entered: 

logTracking.request("param1: " + param1 + " - param2: " + param2
                + " - param3: " + param3 + " - param4: " + param4
                + " - param5: " + param5 + " - param6: " + param6
                + " - param7: " + param7 + " - param8: " + param8
                + " - param9: " + param9 + " - param10: " + param10
                + " - param11: " + param11 + " - param12: " + param12);

We have many methods and do in each of these, is cumbersome, and every time you add or remove some parameter you have to change the log. (Obviously the parameters have a more appropriate name, I put it as an example.)

Is there any way to collect this in a single string and thus save it in the log in String format? I have seen something of WebServiceContext , I have tried something and it has not worked for me, it always comes empty or zero values: link

Thank you very much.

One option would be Handler s, which is the equivalent in JAX-WS at HttpFilter ; small modules that run before or after the main logic. 

public class SOAPLogger implements SOAPHandler<SOAPMessageContext>{
  @Override
  public boolean handleMessage(SOAPMessageContext context) {
      SOAPMessage soapMessage = context.getMessage();
      ...
  }
}

From here you can play with soapMessage to extract the SOAP (or if you prefer, take a more detailed tour of the content of the request). For example, with getSOAPBody , getSOAPPart , etc.

The handlers go in handler "chains", which are declared in a file: 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<javaee:handler-chains
   xmlns:javaee="http://java.sun.com/xml/ns/javaee"
   xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <javaee:handler-chain>
      <javaee:handler>
         <javaee:handler-class>miPackage.SOAPLogger</javaee:handler-class>
     </javaee:handler>
   </javaee:handler-chain>
</javaee:handler-chains>

To indicate that a WS uses a handler chain , you use @HandlerChain 

@WebService
@HandlerChain(file="handler-chain.xml")
public class MiWebService{

   @WebMethod(operationName = "getObject")
   public MyObject getObject(

Another option, much simpler but much less flexible, is to use the system of logs that the platform can offer. For example in WildFly, in the file logging.properties : 
logger.org.apache.cxf.services.MiWebService.level=INFO
logger.org.apache.cxf.services.MiWebService.useParentHandlers=true
