OpenSAML user discussion

Hi

Thanks for reply.

I have got the SAML with namespace and now am able to resolve the "SAXParseException".

 

String fileName = "C:/Users/SamlResponse.xml";

BasicParserPool ppMgr = new BasicParserPool();

ppMgr.setNamespaceAware(true);

Document inCommonMDDoc;

FileInputStream in = new FileInputStream(new File(fileName));

try{

inCommonMDDoc = ppMgr.parse(in);

Element responseRoot = inCommonMDDoc.getDocumentElement();

System.out.println("responseRoot  is:"+responseRoot);

 

UnmarshallerFactory unmarshallerFactory = Configuration.getUnmarshallerFactory();

Unmarshaller unmarshaller = unmarshallerFactory.getUnmarshaller(responseRoot);

 

Response samlresponse = (Response) unmarshaller.unmarshall(responseRoot);

 

}catch (XMLParserException e){

e.printStackTrace();

}catch (UnmarshallingException e){

e.printStackTrace();

}

When I ran the above piece of code, I am presenting with

responseRoot: null

"Exception in thread "main" java.lang.NullPointerException "

 

I am getting the "null", at this  line. Element responseRoot = inCommonMDDoc.getDocumentElement();

Please could you correct me if I am doing wrong in mycode.

 

Thanks

Regards

If your file data is literally as you originally posted, for example:

<Response IssueInstant="2009-09-04T13:37:33Z" MajorVersion="1"
MinorVersion="1" ID="1bc6d017-f9bd-4333-a618-a73cd4ea51ac">


then it is in fact invalid, b/c you don't have any namespace
declarations in there at all. SAML (both v1 and v 2) is always
namespace-qualified.  The schema validation is then correctly reporting
that it does not know about any declaration for a (non-namespace
qualified) Element called 'Response'.

You need to add the appropriate namespace declarations to you SAML data.
