用于大型SOAP响应的jax-ws流

Question

我有一个要求在Stream中提供SOAP响应，因为soap resoponse非常大并且可能导致Outofmemory异常。假设我有一个实体由20个字段组成，没有记录大约10万字节。任何人都知道该怎么做.. ???

public class ReportResponse{

private String name;
private String address;
private String number;

}


  @WebService
  @SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
  @SchemaValidation(handler = SchemaValidationCustomErrorHandler.class)
  public class MyServiceEndpoint {

 @Resource
private final ReportDispatcher dispatcher;

@Resource
WebServiceContext wsContext;

@WebMethod(operationName = "GetReport")
    public List<ReportResponse> getReport()
        throws GenericSoapFault {

    final MessageContext messageContext = this.wsContext.getMessageContext();
     final SAXParseException errorException = (SAXParseException)      messageContext.get(SchemaValidationCustomErrorHandler.ERROR);
    final SAXParseException fatalErrorException = (SAXParseException) messageContext.get(SchemaValidationCustomErrorHandler.FATAL_ERROR);

    String errorMessage = null;

    if (errorException != null) {
        errorMessage = errorException.getMessage();
    } else if (fatalErrorException != null) {
        errorMessage = fatalErrorException.getMessage();
    }

    if (errorMessage != null) {
        if (checkIfDateRangeError(errorMessage)) {
            responseBuilder.withException(new ExceptionBuilder().withInvalidDatesError().build());
            return responseBuilder.build();
        }
        throw new GenericSoapFault(errorMessage);

    }

    return this.dispatcher.generateReport();

  }



}

这里generateReport函数提供的结果大约有几十万。我需要使用Streeaming ...我找到了StreamingDataHandler类......但不知道如何使用它。
