hi Arne ,thank you for your response ,i used the 2nd issue to manually parse the soap response and it gives me errors in this line (System.out.println(n1.getNodeValue());) 
I have even added the namespace context by adding this code       NamespaceContext ctx = new NamespaceContext() {

            public String getNamespaceURI(String prefix) {
                String uri;
                if (prefix.equals("ns1")) {
                    uri = "uri of ns1";
                } else {
                    uri = null;
                }
                return uri;
            }

            public String getPrefix(String namespaceURI) {
                throw new UnsupportedOperationException("Not supported yet.");
            }

            public Iterator getPrefixes(String namespaceURI) {
                throw new UnsupportedOperationException("Not supported yet.");
            }
        };
and still haven't succeed to get the values .
Thanks in advance for your help .
