I've implemented a SAML2 SSO integration with Spring security, and now I'm trying to create a SAMLObject Response from a string() for testing and creating a more robust and safe integration. I've been following multiple projects on Github:
- https://github.com/jrowny/java-saml/blob/master/src/com/onelogin/saml/Response.java
- https://github.com/oaeproject/SAMLParser/blob/master/src/main/java/org/sakaiproject/SAMLParser/SAMLParser.java
and I've came up with this code:
public static XMLObject stringToSAMLResponse(String samlResponse) throws Exception {
BasicParserPool parser = new BasicParserPool();
parser.setNamespaceAware(true);
StringReader reader = new StringReader(samlResponse);
Document doc = parser.parse(reader);
Element samlElement = doc.getDocumentElement();
UnmarshallerFactory unmarshallerFactory = Configuration.getUnmarshallerFactory();
Unmarshaller unmarshaller = unmarshallerFactory.getUnmarshaller(samlElement);
if (unmarshaller == null) {
throw new Exception("Failed to unmarshal");
}
return unmarshaller.unmarshall(samlElement);
}
Unfortunately, this method just doesn't work, I'm getting the following stack trace:
java.lang.Exception: Failed to unmarshal

The String I'm trying to parse is something like this:
