I did an install of 6.1sp2 on HP-UX, fulfilled all pre-reqs in the
release notes. Some jsp apps that worked on 6.0 are failing to compile
on 6.1 sp2.

I installed the /simple apps that ship with the web server and most of
those also give a server error. Before looking into my own apps I
would like to know that all of the samples that use beans work.
Anybody seen anything where the /simple sample apps for 6.1 sp2 fail.
Here is the error log when adding something to the shopping cart on
the cart sample:
