Hi Alex,

thank you very much for your advice! I've found in one implementation of QName the following explanation:
   * <p>Due to a historical defect, QName was released with multiple
  |      * serialVersionUID values even though its serialization was the
  |      * same.</p>
  |      *
  |      * <p>To workaround this issue, serialVersionUID is set with either
  |      * a default value or a compatibility value.  To use the
  |      * compatiblity value, set the system property:</p>
  |      *
  |      * <code>com.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0</code>
  |      *
  |      * <p>This workaround was inspired by classes in the javax.management
  |      * package, e.g. ObjectName, etc.
  |      * See CR6267224 for original defect report.</p>
  |      */
  |     private static final long serialVersionUID;
  |     /**
  |      * <p>Default <code>serialVersionUID</code> value.</p>
  |      */
  |     private static final long defaultSerialVersionUID = -9120448754896609940L;
  |     /**
  |      * <p>Compatibility <code>serialVersionUID</code> value.</p>
  |      */
  |     private static final long compatibleSerialVersionUID = 4418622981026545151L;
  |     /**
  |      * <p>Flag to use default or campatible serialVersionUID.</p>
  |      */
  |     private static boolean useDefaultSerialVersionUID = true;
  | 

In my test code I inserted the value 1.0 for the system property com.sun.xml.namespace.QName.useCompatibleSerialVersionUID:
public void test()
  | {
  |   try {	  
  |     Properties system = System.getProperties();
  |     system.put("com.sun.xml.namespace.QName.useCompatibleSerialVersionUID", "1.0");
  |     System.setProperties(system);
  | 
  |     Properties properties = new Properties();
  |     properties.setProperty("java.naming.provider.url","jnp://localhost:1099");
  | properties.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
  |     properties.setProperty("java.naming.factory.url.pkgs","org.jboss.naming.client");
  |     properties.setProperty("j2ee.clientName", "jbpmbpel-client");
  |     Service service = null;
  |     if (service == null) {
  |       InitialContext iniCtx = new InitialContext(properties);
  |       Object object = iniCtx.lookup("java:comp/env/service/Hello");
  |       service = (Service)object;
  |       String portTypeNS = "http://jbpm.org/examples/hello";
  |       Call call = service.createCall(new QName(portTypeNS, "GreeterPort"),"sayHello");
  |       String greeting = (String) call.invoke(new Object[] { "Olive" });			    
  |       System.out.println("Greeting: "+greeting);
  |     }
  |   } catch (Exception e) {
  |       e.printStackTrace();
  |   }
  | }
With this code code I got an answer:
