Opensaml error receiving correct unmarshaller

I am running this code at opensaml2.6

Element metadataRoot = document.getDocumentElement();

// Unmarshall
UnmarshallerFactory unmarshallerFactory = Configuration.getUnmarshallerFactory();
Unmarshaller unmarshaller = unmarshallerFactory.getUnmarshaller(metadataRoot);
if (unmarshaller == null) {
    System.out.println("Error receiving unmarshaller for this document.");
    return;
}

For the document

<?xml version="1.0" encoding="UTF-8"?><saml2:EncryptedAssertion xmlns:saml2="urn:oasis:names:tc:SAML:2.0:assertion">

Unmarshaller return a null, Can you help me to undertand how are the criterias to lookup the correct Unmarshaller and how this works at opensaml?

Solution

  • I found that there is not unmarshallers register as there is not initialization in the library:

    Important piece of code:

    // Initialize the library
DefaultBootstrap.bootstrap();
