Hi Everyone, I am using the SAML2.0 module in my application. It is a 9.2.0 app so I have had to export the SAML module in version 8.*, and then import it into my 9.2 app. That seemed to go fine, but then when trying to run the app I get an error: Unable to add RequestHandler to path 'SSO/': and then when trying to go to the /SSO URL, I get: 404 - file not found for file: SSO/ (obviously because of the first error. Is there anything that I can do? I really don’t want to take weeks redeveloping my application in 8.*. Am I able to maybe write a custom Java function that would handle the RequestHandler? Has anyone else experienced this? Help!! The full first error is: java.lang.ClassCastException: class org.opensaml.core.xml.schema.impl.XSAnyBuilder cannot be cast to class org.opensaml.xml.XMLObjectBuilder

I had the same error migrating from Mx8 to Mx9.2.0 and updating to SAML20 version 3.0.5.
Ultimately I was able to resolve it by deleting "org.apache.servicemix.bundles.opensaml-2.6.0_3.jar". In general: I searched for 'SAML' in the userlib directory. Files were either recent from the app store update or old from earlier version. I cleaned any SAML reference with an old date.

That looks like a version conflict to me.
You might have multiple versions of opensaml in your userlib directory. Look for files starting with opensaml and drop all of them that have a version number below 3.4.5 (assuming you’re using the latest released SAML module).
