          Quick fix:
          Add the following code into your "Client.java" class "getInitialContext()" method

          public static Context getInitialContext()
          throws javax.naming.NamingException
          {
          Properties p = System.getProperties();
          p.put("com.sun.xml.namespace.QName.useCompatibleSerialVersionUID", "1.0");

          System.setProperties(system);

          return new javax.naming.InitialContext();
          }


          DO not forget to import:
          import java.util.Properties;

          Then, it should work.

            Sorry for the typo. Here is the right one:

            public static Context getInitialContext()
            throws javax.naming.NamingException
            {
            Properties p = System.getProperties();
            p.put("com.sun.xml.namespace.QName.useCompatibleSerialVersionUID", "1.0");

            System.setProperties(p);

            return new javax.naming.InitialContext();
            }
