OpenSAML user discussion

[lakshmi narasimhan <>]

Hi,

 

I'm able to get over the bootstrap initialization problem. However, when I try to parse the Base64-decoded SAML, the document object is coming up as null. Here's the code snippet which I'm using for this purpose:

 

String samlResponseB64Str = (String)session.getAttribute("samlToken"); 
 DefaultBootstrap.bootstrap();      
   
    // Decodage URL encoding with Base64
    String samlResponseStr = new String(Base64.decode(samlResponseB64Str),"UTF-8");
    out.println("<br/> Base64 decode of SAML: "+samlResponseStr);
  
 // Get parser pool manager
    BasicParserPool pp = new BasicParserPool();
    pp.setNamespaceAware(true);
       
 Document doc = pp.parse(new StringReader(samlResponseStr)); 
 out.println("Document is: "+doc); 

 

Any thoughts please?

 

Thanks,

Laks.

This comes from having an older version of Xalan or Xerces on your classpath somewhere.  You'll need to examine your classpath and make sure that you have only one version, and that that version is up to date.

Hi,

I'm trying to parse a SAML token and while initializing bootstrap(DefaultBootstrap.bootstrap();), I'm encountering the error message pasted below. I'm using xalan-2.7.0.jar in my classpath. I tried using xalan-2.6.0.jar too but was getting the same error message. Any suggestions would be gratefully received.
