question about marshalling using openSAML2 in a servlet environment

[Chad La Joie]

Please start with the opensaml documentation[1] that describes it's
basic usage.  It discusses how to initialize the library (which is the
error you're seeing right now) and how to properly do the marshalling
(which you're not doing right now).

In order to do that I am trying to marshall the SAML Authentication Request using 'org.opensaml.saml2.core.impl.AuthnRequestMarshaller#marshall(AuthnRequest)'.

However when I run it as a servlet component I get an error saying "No marshaller available for {urn:oasis:names:tc:SAML:2.0:assertion}Issuer, child of {urn:oasis:names:tc:SAML:2.0:protocol}AuthnRequest", where Issuer is a component of the AuthnRequest object.
