hi....I use my client to call a web service binding with a my ejb. The client is:

1 URL url = new URL(
2 "http://brodo:8080/EsempioJ2EE/EsempioWS/EsempioWebService?wsdl");
3
4 QName qname = new QName("http://brodo:8080/", "EsemploWebService");
5
6 ServiceFactory factory = ServiceFactory.newInstance();
7 Service service = factory.createService(url, qname);
8
9 EsempioWebService endpoint = (EsempioWebService) service
10 .getPort(EsempioWebService.class);
11
12 System.out.println(endpoint.somma(1, 1));

until the 12 row it's all ok. When I go in the 12 row I have this error:

Exception in thread "main" java.rmi.RemoteException: null; nested exception is:

I've gone into the code and I've seen that the problem is in org.jboss.axis.encoding.DeserializationContextImpl class in the .parse() method:

/**

• Create a parser and parse the inputSource
  */
  1 public void parse() throws SAXException
  2 {
  3 if (inputSource != null)
  4 {
  5 SAXParser parser = XMLUtils.getSAXParser();
  6 try
  7
  Unknown macro: {8 parser.setProperty("http}

  21 catch (IOException e)
  22

  { 23 throw new SAXException(e); 24 }

  25 inputSource = null;
  26 }
  27 }

if I use jdk 1.5 automaticallly I use the jaxp 1.3 implementation by sun. Indeed the "parser" variable in my case is equal to com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl and it cannot to accept a null parameter in the setProperty method because it return a NullPointerException
