Velocity code not rendering in error.vm

[Wessel, Keith]

springContext sounds promising, but can I use it to pull in a variable that I'm defining on Jetty start-up with a java -Dfoo=bar arg? I can't see any easy way to do that with a blobal spring bean.

I'm starting to think that the easiest thing might be to skip displaying the IDP node name in my error template if $environment isn't defined. But I haven't give up yet.

I looked at the code, and I created a class that attempts to populate a few things of use through the MVC layer:

* request
* encoder
* springContext

The springContex variable in particular could probably get at global Spring beans by name.

More exotically, the class I built there (net.shibboleth.ext.spring.error.ExtendedMappingExceptionResolver) theoretically can take a function at build time that can dynamically add additional attributes to the view, but that isn't wired up at the moment. I suspect you can probably get enough done with the existing behavior.

And no, I didn't remember doing any of that when you first asked.
