how to build Document/Literal (Wrapped)

[everjava]

I didn't understand very well the example from docs. My doubt is about  @RequestWrapper and @ResponseWrapper.  How is the SubmitPO and SubmitPOResponde implementation ?

@WebService
public class DocWrappedServiceImpl
{
   @WebMethod
   @RequestWrapper (className="org.somepackage.SubmitPO")
   @ResponseWrapper (className="org.somepackage.SubmitPOResponse")
   public String submitPO(String product, int quantity)
   {
      ...
   }
}

I have this code below. I'm using jboss 5.1 + esb4.9 + jbossws native  3.1.2.GA. But I got the error

"Endpoint .... does not contain operation meta data for ..."

myMethod(object param) gets an array from client written in php

@WebService(name="PessoaWS" ,targetNamespace="http://scxx" )

@SOAPBinding(style = Style.DOCUMENT, use=Use.LITERAL, parameterStyle=ParameterStyle.WRAPPED)

public class PessoaWS {

    @WebMethod

    public void myMethod( Object param){

        try {

            Message esbMessage = SOAPProcessor.getMessage();

            String soap = esbMessage.getBody().get().toString();

            System.out.println(soap);

        } catch (Exception e) {

            e.printStackTrace();

        }

    }
