NullPointerException on linux but not win2000
Apologies if I've missed something obvious.
The test jsp page below works on windows 2000 with tomcat 4.0.4, but throws
a NullPointerException (see the stack trace below) under Debian linux with
tomcat 4.0.4. (N.B. This is the same problem as described by Adam Lipscombe
in an earlier message.)

Any ideas?

I am able to run an equivalent test program from the command line which
suggests that it the problem may be caused by tomcat's security manager.
