Hello Everybody,

In order to test Post Binding I wrote a small test program using HttpPostEncoder. In oder to decode on server end I am using HttpPostDecoder. However I get following error:

23:15:22,938 DEBUG [Configuration] VM using JAXP parser org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

23:15:22,949 DEBUG [BaseMessageDecoder] Beginning to decode message from inbound transport of type: org.opensaml.ws.transport.http.HttpServletRequestAdapter

23:15:22,950 DEBUG [HTTPPostDecoder] Decoded SAML relay state of: null

23:15:22,950 DEBUG [HTTPPostDecoder] Getting Base64 encoded message from request

23:15:22,950 ERROR [HTTPPostDecoder] Request did not contain either a SAMLRequest or SAMLResponse paramter.  Invalid request for SAML 2 HTTP POST binding.

23:15:22,952 ERROR [STDERR] org.opensaml.ws.message.decoder.MessageDecodingException: No SAML message present in request

am I doing something wrong.? Your input will be highly appreciated.

Thank you.

Encoding end looks like following:

public FooHTTPPostEncoder( String templateId,String key,String cert, HttpServletResponse response ) throws Exception

{

   velocityEngine = new VelocityEngine();

       velocityEngine.setProperty(RuntimeConstants.ENCODING_DEFAULT, "UTF-8");

       velocityEngine.setProperty(RuntimeConstants.OUTPUT_ENCODING, "UTF-8");

       velocityEngine.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");

       velocityEngine.setProperty("classpath.resource.loader.class",

               "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");

       velocityEngine.init();

       this.setTemplateString(templateId);

   

   ................................

        ............................

                < build AuthnRequest using available builders>

 

        authnRequest=samlAuthnRequest.buildAuthnRequest();

 this.basicSAMLMessageContext=new BasicSAMLMessageContext();

 Endpoint endPoint=samlAuthnRequest.getEndPoint(this.actionURL);

 

 this.basicSAMLMessageContext.setPeerEntityEndpoint(endPoint);

 this.basicSAMLMessageContext.setOutboundSAMLMessage(authnRequest);

  

 HttpServletResponseAdapter adapter = new HttpServletResponseAdapter(response,false);

 this.basicSAMLMessageContext.setOutboundMessageTransport(adapter);

 this.basicSAMLMessageContext.setOutboundSAMLMessageSigningCredential(this.samlAuthnRequest.getSamlCommon().getCredential());

       

}

     public String getTemplateString()

{

return templateString;

}

public void setTemplateString( String templateString)

{

this.templateString = templateString;

}

public void encode() throws MessageEncodingException{

     HTTPPostEncoder encoder = new HTTPPostEncoder(velocityEngine,

         this.templateString);

         encoder.encode(this.basicSAMLMessageContext);

     }

Decoding:

                HTTPPostDecoder decode = new HTTPPostDecoder( new BasicParserPool() );

       HttpServletRequestAdapter adapter = new HttpServletRequestAdapter(request);

       context = new BasicSAMLMessageContext();

        context.setInboundMessageTransport(adapter);

                 decode.decode(context);

     

      samlRequest = (AuthnRequest) context.getInboundMessage();
