OpenSAML user discussion

[<>]

Hi, Can you please help me with this issue. Thank you so much in advance.

I used below code to read the SAML response:

      HTTPPostDecoder decode = new HTTPPostDecoder( new BasicParserPool() );
      HttpServletRequestAdapter adapter = new
HttpServletRequestAdapter(request);
      BasicSAMLMessageContext context = new BasicSAMLMessageContext();
      context.setInboundMessageTransport(adapter);
      decode.decode(context);
      relayState = adapter.getParameterValue(this.RELAY_STATE_PARAM); //
decode.getRelayState();
      // Only decode the relay state if there is one
      if ((relayState != null) && (relayState.equalsIgnoreCase("") == false))
{
         relayState = new String(Base64.decode(relayState));
      }

    XMLObjectBuilderFactory builderFactory =
org.opensaml.Configuration.getBuilderFactory();
     ResponseBuilder rspBldr = (ResponseBuilder)
builderFactory.getBuilder(Response.DEFAULT_ELEMENT_NAME);       
     Response rsp = rspBldr.buildObject();
     rsp = (Response) context.getInboundMessage();
     this.inResponseTo = rsp.getInResponseTo();
     LOGGER.debug("Completed Step1");
     if(inResponseTo != null) {
     LOGGER.debug(inResponseTo.toString());
     }

This code is working without any problem for below xml:

But it is not able to read samlp:Response tag. Any idea where I can define the
name space and read this samlp:Response xml object
