[keycloak-dev] changing adapter error handling

Any servlet based adapter will now be using HttpServletResponse.sendError with the appropriate Http status code of the protocol. To handle errors, users will have to add the appropriate error code handlers in web.xml. I should have done that in the first place, but quite honestly, I didn't even know that existed in the servlet spec. I'll be setting a request attribute that contains a protocol specific object so that people can view the error code, message, or anything else the protocol provides (i.e. SAML errors can be quite complex and can have their own document). Hopefully I"ll have this done by tomorrow. -- Bill Burke JBoss, a division of Red Hat http://bill.burkecentral.com
