Just wanted to let everyone know that got all this resolved.  For
testapp2 and introspect, I didn't have template-root set correctly.
For testapp3, it didn't recognize static-string, so I changed it to
text-area, and it worked fine.  For echo-app, area in class echoer was
getting initialized to nil, so I changed

        (write-string area stream)

to

        (when area
          (write-string area stream))

in the render-html method, and everything was fine.

Thanks to all who replied,
